Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a pressure pump that can easily extract air remaining in a container and inject air in order to smoothly pump a high viscosity material. This relates to improvements in equipment.

[Conventional technology]

2. Description of the Related Art Conventionally, as a pressure pump device for feeding high viscosity materials such as grease, the one shown in FIG. 9 is known. In this system, an inductor plate 2 provided with a wiper 3 is slidably and tightly fitted into a container 1 containing a high-viscosity material a, and an air discharge hole 26 is connected to a connector 6 connecting the pump body to the inductor plate 2.
A valve body 25 is provided in an inclined manner, and an operating rod 27 is screwed onto the valve body, and a check valve 28 for injecting air is attached to the connecting body 6. Rotate the rod 27 to open the air discharge hole 26 to remove the residual air, and when removing the inductor plate 2 from the container 1, open the check valve 28.
Compressed air is forced into the container.

[Problem that the invention seeks to solve]

However, since the operating rod 27 for air bleeding is installed in a sloping manner in a narrow space between the connecting body 6 of the pump body and the container 1, it is difficult to operate, and it is difficult to unscrew or screw in the operating rod 27. , the operation is time-consuming, and there is a risk that material may be ejected along with air, especially during unscrewing. Furthermore, the mechanical parts of check valves for air injection tend to become dirty, and the material leaks from the seat, causing problems such as sticking and impairing the function of the check valve.

Therefore, the present invention solves the above problems in view of the conventional problems, and makes it possible to perform the air bleeding operation and the air injection operation easily and quickly, reliably, and to make it robust and prevent malfunctions. There is no need to get any equipment.

[Means for solving problems]

As a means to achieve this, the high viscosity material pressure pump device of the present invention has a valve attached to the lower end of the operating rod in an air vent hole bored in an inductor plate fitted into a container containing the high viscosity material. The spring presses the packing of the valve body against the inductor plate, and the operating rod is biased so that the air vent hole automatically returns to the normally closed state, and the operating rod is tilted. It is characterized in that the duct plate is installed upright, and by tilting the operating rod, the air vent hole can be opened and the residual air in the container can be discharged.Furthermore, the operating rod is hollow and forms an air introduction path. A check valve is attached to the valve body at the lower end of the inductor plate so that air can be injected into the container, or a diaphragm-based check valve is installed in the air injection hole of the inductor plate to inject air into the container. It is designed so that it can be attached.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described in detail below.

1 to 7 show a first embodiment of the present invention, in which 1 is a container containing a high-viscosity material a, 2 is an inductor plate, and the wiper 3 attached to the outer periphery is used to wipe the container 1. Fits tightly and can move freely. Reference numeral 4 denotes an air vent hole formed in the inductor plate 2, into which a valve body 9 of an operating rod 7, which will be described later, is loosely fitted. 5
is a pump body attached to a connecting body 6 erected on an inductor plate. Reference numeral 7 designates an operating rod having an air introduction passage 8, a valve body 9 is attached to the lower end, it loosely fits into the air vent hole 4, and a packing 11 for a valve seat is attached on the stud 10 at the lower end. Tighten and fix the washer 12 with a nut,
A spring 13 is elastically installed between the washer 12 and the inductor plate 2, and the packing 11 is pressed against the air vent hole 4, so that the operating rod 7 can be tilted, and is normally biased to stand upright. do.
A joint 14 for introducing air is connected to the upper end of the operating rod 7, and a diaphragm 15 made of rubber, Teflon, etc. is shown in FIG. 4 to cover the lower end of the operating rod 7 and the lower surface of the stud 10 of the valve body 9. Fix the four corners of the stud 10 with screws 16 as shown.

The inductor plate 2 to which the pump body 5 is attached is fitted into the container 1, so that the high viscosity material a in the container 1 is pumped out.
When removing the residual air b in the container 1 on the lower surface of the inductor plate 2, press the upper end of the operating rod 7 sideways as shown in FIGS. 2 and 6. As a result, the operating rod 7 is tilted using the stud 10 of the valve body 9 at the lower end as a fulcrum, and a gap is formed between the packing 11 of the valve body 9 and the air vent hole 4. The residual air b in the container 1 is discharged to the outside in the direction of the arrow in FIG.

After the air has been released, when the pressure on the operating rod 7 is released, the operating rod 7 automatically returns to its upright position due to the elastic action of the spring 13, and the entire packing 11 of the stud 10 comes into pressure contact with the air vent hole 4. Container 1
The high viscosity material a inside is prevented from flowing out.

When removing the inductor plate 2 from the container 1, air is supplied from the outside into the operating rod 7 via the air introduction joint 14, as shown in FIGS. 3 and 5. This air passes through the hollow air introduction passage 8 in the operating rod 7 and reaches the diaphragm 15 attached to the stud 10 at the lower end, but since the diaphragm 15 is fixed at the four corners with screws 16, there are gaps between the fixed points. The diaphragm 15 of
As shown in the figure, it is spread out by air and distributed.
Injected into container 1. This increases the internal pressure within the container 1, allowing the inductor plate 2 to be easily removed from the container 1.

Note that when air is not injected, the diaphragm 15 is pressed against the stud 10 by the pressure of the high viscosity material and the gap is closed, so that the high viscosity material a does not flow back into the air circuit.

FIG. 8 shows a second embodiment of the present invention, and in this embodiment, the air bleed mechanism and the air injection mechanism are made independent.

The air bleeding mechanism is the inductor plate 2
An operating rod 17 is loosely fitted into the air vent hole 4 of the inductor plate 2, and a packing 19 is attached to the stud 18 connected to the lower end of the operating rod 17.
A coil spring 21 is installed between the spring receiver 20 attached to the operating rod 17 on the upper surface side and the inductor plate 2.
By elastically installing the packing 19, the packing 19 is brought into pressure contact with the air vent hole 4 to close the valve, and the operating rod 17 is erected in an upright position that can be tilted.

The air injection mechanism is the inductor plate 2
A boss 23 with a screw for an air coupling is attached to an air injection hole 22 bored in the air injection hole 22, and the lower surface of the air injection hole 22 is covered with a diaphragm 24 fixed at several points.

Therefore, when venting air, push the operating rod 17 and tilt it so that the stud 18 resists the coil spring 21.
By forming a gap between the container 1 and the inductor plate 2, residual air b in the container 1 can be discharged to the outside.

Furthermore, when injecting air, by injecting air into the boss 23 through the joint, air can be supplied into the container 1 by forming a gap between the attachment parts of the diaphragm 24, and the inductor Plate 2 can be easily removed from container 1.

〔Effect of the invention〕

As described above in detail with respect to various embodiments, the present invention allows the valve to open simply by manually pushing down the operating rod, allowing the residual air in the container to be reliably discharged, and the spring action to release the handle. The operating rod automatically returns to the upright position and closes quickly and securely, preventing the high viscosity material in the container from leaking out. Even when operating in a narrow space, the operating rod can be easily closed using the conventional screw type. It can be operated more quickly and reliably than other devices. In addition, the air-injected check valve uses a diaphragm that is fixed at several points around the periphery, so it does not become inoperable due to high viscosity materials, operates reliably, is easy to clean and disassemble, and is robust. Therefore, it is possible to obtain a device that does not cause any malfunction or the like.
