Description

Rubber-membrane-sealed dry-type gas holders with capacity indication

technical field

The utility model belongs to the field of gas cabinets, in particular to a rubber film-sealed dry gas cabinet with scales and a tank capacity indicating function.

Background technique

Rubber-membrane-sealed dry-type gas holders are widely used in the storage of industrial and civil gas, which realizes the throughput of gas through the up and down movement of the piston in the gas holder. For the operation and management personnel of the gas cabinet, it is very important to know the operating position of the gas cabinet piston and the gas storage volume of the gas cabinet. The rubber membrane sealed dry-type gas tank is also equipped with traditional tank capacity indication methods, mainly including optical fiber counter gauge, mechanical counter gauge, ultrasonic counter gauge and radar counter gauge. The principle of the optical fiber counter meter is to fix one end of the steel wire rope on the piston of the gas cabinet, and the other end is fixed on the measurement hinge wheel of the counter meter. When the piston moves, it drives the winch wheel to rotate, and the signal generated is converted into a cabinet compatible signal output. The principle of the mechanical counter gauge is to fix one end of the steel wire rope on the piston of the gas tank, and the other end is connected to the transmission gear of the counter gauge. When the piston moves, it drives the transmission gear to rotate, and the specific gear transmission ratio is set to convert the displacement of the steel wire rope into a counter The position of the pointer on the dial of the meter. The principle of the ultrasonic counter meter and the radar counter meter are similar. Both ultrasonic or radar sending and receiving devices are arranged on the top of the gas cabinet and the piston. By measuring the signal transmission time, the distance between the top of the cabinet and the piston is calculated, and then passed The formula converts it into a cabinet capacity signal and outputs it to the operator.

For the traditional tank capacity indication method, it is widely used in rubber membrane sealed dry gas tanks. However, practice has proved that there are many defects: (1) The principles of optical fiber counter gauges and mechanical counter gauges are complicated, and the installation accuracy is very high. They rely too much on key equipment such as measuring hinge wheels and transmission gears. (2) Ultrasonic counter gauges and radar counter gauges use ultrasonic or electromagnetic wave reflection technology, which is more accurate in ideal conditions, but the cost is high and the environment is very demanding , the anti-interference ability is weak. For example, because the piston tends to have a certain inclination, the reflected wave is often not well received or not accurate enough, so it cannot be applied to harsher working conditions.

Contents of the invention

In order to overcome the above-mentioned defects in the traditional tank capacity indication method, the technical problem to be solved by the utility model is: to provide a rubber membrane sealed dry gas tank with tank capacity indication, which is simple, practical, safe and reliable for tank capacity indication.

The technical scheme that the utility model takes for solving the problems of the technologies described above is:

A rubber-membrane-sealed dry-type gas cabinet with a cabinet capacity indication, characterized in that: the leveling counterweight is suspended outside the side wall of the gas cabinet by a leveling wire rope, and a cabinet capacity pointer is set on the leveling configuration; the other end of the leveling wire rope extends into In the gas tank, and connected to the gas tank piston in the gas tank; the leveling counterweight guide rail matched with the leveling counterweight is set on the outer wall of the gas tank; one side of the leveling guide rail is set on the outer surface of the side wall of the gas tank Cabinet capacity scale; the movement range of the cabinet capacity pointer is within the range of the cabinet capacity scale.

According to the above technical scheme, the movement direction of the balancing weight is opposite to that of the piston, but the movement displacement is equal.

According to the above-mentioned technical scheme, a group of cameras and their signal transmission system are arranged on the periphery of the gas cabinet body, and the shooting range of the cameras covers the pointer of the cabinet and the scale of the cabinet.

According to the above-mentioned technical scheme, the leveling counterweight is suspended by two leveling wire ropes, and the other ends of the two wire ropes are respectively connected with the gas tank piston.

The painting principle of the scale of the tank capacity is as follows: when the piston of the gas tank falls to the bottom and is inflated, the volume of the gas tank is regarded as 0 cubic meters at this time, and the position of the balance weight should also be marked as 0 cubic meters at this time; the piston of the gas tank rises At the moment when it reaches the top and touches the automatic relief valve, the volume of the gas tank is regarded as full volume at this time, and the position of the balance weight should also be marked as full volume at this time. The distance between the two is divided linearly again, and the distribution of the scale of the cabinet capacity is obtained at this time. The painting mark of the scale of the tank capacity should be carried out after the air adjustment of the gas tank, and the start and end points of the scale should be consistent with the landing position of the piston and the start of automatic release respectively.

When the gas holder is constantly filled with gas, the gas holder piston will continue to rise, and the balance weight will continue to fall. On the contrary, when the gas holder outputs gas, the piston will fall, but the piston weight will rise. The cabinet capacity pointer is set on the leveling counterweight, and the cabinet capacity scale is set on the side wall on the side of the leveling counterweight guide rail. The movement direction of the balance weight is opposite to that of the piston, but the resulting displacement is the same, so the position of the balance weight can represent the position of the piston, which can also represent the gas storage volume of the gas tank. This relationship is continuous, Linear and stable. Through the cabinet pointer and the cabinet scale, we transform this relationship into a specific value for reading. Real-time remote control can be realized by transmitting the data captured by the camera to the operator.

For newly-built or already built gas cabinets, the method of adding this cabinet capacity indicating device is very simple. It only needs to determine the relative relationship between the gas cabinet piston and counterweight, and the relationship between the piston position and the gas storage volume of the gas cabinet through calculation. Painting schemes for volumetric scales can be determined. Use paint to paint the volume scale on the edge of the side wall leveling weight guide rail according to the calculated rules, paint the pointer on the leveling weight, and then set up a camera and its signal transmission system. The whole system is simple and practical, reliable and durable, and low in cost.

The utility model utilizes the linear linkage relationship between the piston and the leveling counterweight, and converts the invisible movement of the piston inside the cabinet into the form of the movement of the leveling counterweight visible outside the cabinet, thereby realizing the cabinet capacity indicated function. The utility model has the characteristics of simplicity, practicability, reliability and durability, and low cost, and can be used as a beneficial supplement for gas tank capacity indication.

Detailed ways:

The new embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, a leveling counterweight 7 is vertically suspended outside the gas cabinet side wall 3 through a first leveling wire rope 5 and a second leveling wire rope 6, and a cabinet capacity pointer 9 is set on the leveling configuration; Flat wire rope 5 and the second leveling wire rope 6 extend into the gas holder respectively from the junction of the gas holder top 1 and the side wall of the gas holder, and are connected on the gas holder piston 2 in the gas holder.

As shown in Figure 2, the gas cabinet side wall 3 outside is vertically provided with the leveling counterweight guide rail 8 matching the leveling counterweight 7 from the gas cabinet bottom plate 4; The surface is coated with a cabinet scale 10; the moving range of the cabinet pointer 9 is within the range of the cabinet scale 10. Figure 2 takes a 100,000 cubic meter rubber-membrane-sealed dry-type gas tank as an example, showing the position of the counterweight when the piston is at the lowest and highest positions, that is, the indication of the tank capacity at this time.

The painting principle of the tank capacity scale 10 is: when the gas tank piston 2 falls to the bottom and is inflated, the volume of the gas tank is regarded as 0 cubic meters at this time, and the position of the balance weight should also be marked as 0 cubic meters at this time; The moment the piston rises to the top and touches the automatic relief valve, the volume of the gas tank is regarded as full volume at this time, and the position of the balance weight should also be marked as full volume at this time. The distance between the two is divided linearly again, and the distribution of the scale of the cabinet capacity is obtained at this time. The painting mark of the scale of the tank capacity should be carried out after the air adjustment of the gas tank, and the start and end points of the scale should be consistent with the landing position of the piston and the start of automatic release respectively.

A group of cameras and its signal transmission system are arranged around the gas cabinet body, and the indications of the cabinet capacity pointer 9 and the cabinet capacity scale 10 are transmitted to gas cabinet operators for real-time viewing.

By leveling the cabinet capacity pointer on the counterweight and leveling the cabinet capacity scale on the side wall of the edge of the counterweight guide rail, the reading of the gas tank capacity is realized.

When the gas holder is constantly filled with gas, the gas holder piston 2 will continue to rise, and the leveling counterweight 7 connected to the piston through the first leveling wire rope 5 and the second leveling wire rope 6 will continue to decline, otherwise, when When gas is output in the gas holder, the piston will descend, but the piston counterweight will rise. The cabinet capacity pointer 9 is arranged on the leveling counterweight, and the cabinet capacity scale 10 is arranged on the outer surface of the gas cabinet side wall 3 on the leveling counterweight guide rail 8 sides. The movement direction of the balance weight is opposite to that of the piston, but the resulting displacement is the same, so the position of the balance weight can represent the position of the piston, which can also represent the gas storage volume of the gas tank. This relationship is continuous, Linear and stable. Through the cabinet capacity pointer and the cabinet capacity scale, we transform this relationship into a specific value, which is captured and transmitted to the operator through the camera for reading.

For newly-built or already built gas cabinets, the method of adding this cabinet capacity indicating device is very simple. It only needs to determine the relative relationship between the gas cabinet piston and counterweight, and the relationship between the piston position and the gas storage volume of the gas cabinet through calculation. Painting schemes for volumetric scales can be determined. Use paint to paint the volume scale on the edge of the side wall leveling weight guide rail according to the calculated rules, paint the pointer on the leveling weight, and then set up a camera and its signal transmission system. The whole system is simple and practical, reliable and durable, and low in cost.

Above embodiment is only preferred embodiment of the present utility model, is not to do more restriction to the present utility model, every simple modification or equivalent change and modification are all still belonged to the scope of protection of the present utility model according to the technological essence of the present utility model .
