Background technique

At present, these joints mainly play the role of connection and do not have other functions. There are generally two ways to supply water to buildings at present, one is to use a booster pump to send water from bottom to top, and the other is to place a water tank on the roof and use the water level difference to transport water from top to bottom. Regardless of the water delivery method, the water pressure on different floors will be different, resulting in different water output on different floors. the

In the patent document with the application number 200910098530.3, a water-saving pipe joint and its opening or closing method are disclosed. The advantage is that it has the dual functions of the pipe joint and the shut-off valve. The disadvantage is that it does not have the ability to adjust pressure. the

In the process of using water, the water pipe joint can be automatically adjusted according to the change of water pressure, so that the water output can be kept within the set maximum range. The disadvantage is that in the process of use, since the setting of the maximum water output is adjusted from the water inlet, and the adjustment effect can only be seen when the water pipe joint is installed on the tap water pipe, when repeated adjustments are required to achieve a satisfactory water output, it is necessary to It is not convenient to adjust the water pipe joint repeatedly. the

Especially for home users, due to the different uses of each faucet, the requirements for water output are also different. It is enough to maintain the water output of the faucet at 4 liters per minute, while the water output of the shower head is required to be above 8 liters per minute. Therefore, the user also needs to adjust the maximum output of each faucet. The water pipe joint is installed on the tap water pipe in front of the faucet. In order to set the water output of each faucet, it is necessary to close the main gate, then remove the water pipe joint, and then install the water pipe joint after adjustment to see whether the water volume is appropriate. If If it is not suitable, it has to be removed and readjusted. Repeat this many times until a satisfactory water output is reached, and then install the faucet. It is troublesome to constantly switch the main gate to see the change of water volume, and the other is to affect the normal use of other faucets. the

Therefore, it is necessary to find a way to adjust the water output of each faucet without switching the main switch. the

Detailed ways

As shown in FIGS. 1 to 3 , the faucet faucet is installed on the spout of the faucet and mainly consists of a housing 1 , a valve core 2 , a bracket 3 , a spring 4 and a nut 5 . the

As shown in Figure 5, the spool 2 includes a valve head 21 and a valve stem 22. More than two drain holes 23 that penetrate the valve head are arranged on the valve head. External threads in the thread phase area.

An inwardly protruding valve seat 11 is provided on the inner wall of the middle part of the housing, and a through hole is provided in the center of the valve seat.

As shown in Figure 4, the bracket is composed of two concentric rings, the inner hole of the ring in the middle is a fixing hole for fixing the valve stem, and the two rings are connected by evenly arranged bracket arms 31, between the bracket arms A fan-shaped water hole is formed, and the outer wall of the bracket is provided with an outer thread matching the inner thread of the inner wall of the housing.

The valve stem is provided with a stop lug 25 around the valve stem. The diameter of the stop lug is greater than the diameter of the fixing hole inner hole of the bracket, so that the lug cannot enter the fixing hole and acts as a stop. The stop lug is preferably arranged at a position where the valve stem is close to the valve head.

A regulating arm 24 extending toward the direction of the valve stem is provided on the wall surface of the valve head at one end of the valve stem; Arms intersect.

Pass the valve stem through the fixing hole and then pass through the spring. At the same time, insert the adjusting arm into the water hole between the bracket arms, screw the nut 5 onto the valve stem, fix the spring between the nut and the bracket 3, and then insert the The bracket is screwed into a suitable position in the housing from the water inlet of the housing in the direction that the nut faces the water inlet to set the maximum water intake.

An adjustment device for adjusting the position of the bracket in the housing is provided on the wall of the valve head facing the water outlet. The adjusting device is an inner hexagonal groove or a slot or a cross recessed to the inner wall of the valve head, which matches with a corresponding inner hexagonal tool or a slotted or crossed tool. When it is necessary to adjust the maximum water output, insert the tool that matches the adjustment device into the adjustment device from the water outlet end of the shell, rotate the tool, and the valve head will rotate accordingly, thereby driving the adjustment arm to rotate, and the rotation of the adjustment arm will push and The intersecting bracket arm rotates, and the bracket arm rotation can change the position of the bracket in the valve body, thereby adjusting the water output.

The quantity of described adjusting arm 24 can be set to one or more, preferably double or twice the number of support arms, as shown in Figure 3 and Figure 4, when the quantity of adjusting arm 24 is identical with the quantity of support arm , the regulating arm is evenly distributed on the valve head. As shown in Figure 5, when the number of regulating arms is twice the number of support arms, the regulating arms are divided into two groups and evenly distributed on the valve head, and the distance between the two regulating arms of the same group is greater than that of the support arms The thickness, that is, a set of two adjustment arms sandwiches a support arm. The drain hole is preferably arranged on the valve head between two adjacent regulating arms. The length of the adjustment arm is usually less than the length of the valve stem, but must be able to intersect the bracket arm.

When assembling, the valve stem is first passed through the fixing hole of the bracket, and the adjusting arm is passed through the water hole. If you choose a cylindrical spring, put the spring on the valve stem so that the spring is located in the gap between the outer wall of the valve stem and the adjustment arm. If you choose a tower spring, put the spring on the valve stem to make the adjustment The arm is seated in the bore of the tower spring. Then screw the nut on the valve stem, and set the prestress of the spring accordingly according to the requirement of the maximum water output. The closer the nut is to the bracket, the greater the prestress of the spring.

The inner wall of the housing close to the valve seat 11 protrudes inward to form an annular platform 12 to prevent the bracket from getting too close to the valve seat. When the bracket is too close to the valve seat, the valve head enters the valve seat to block the valve seat, and the valve head cannot play the role of regulating the water output through the change of position.

The maximum diameter of the valve head is greater than the minimum diameter of the through hole, but smaller than the diameter of the inner hole of the platform, so that water can flow through the gap between the valve head and the inner wall of the housing.

The drain holes are evenly distributed on the valve head, and the drain holes are arranged in parallel with or inclined to the axis of the valve head from the water inlet end to the water outlet end. the

When the water flow pressure is normal, the strength of the water flow is not enough to overcome the prestress of the spring, so the position of the valve head will not change, and the water flows through the gap between the valve head and the inner wall of the housing; when the water flow pressure gradually increases beyond the spring When prestressed, the water flow pushes the valve head to move toward the valve seat, thereby compressing the spring. At this time, the valve head gradually enters the valve seat. When the water flow pressure is too high, the valve head completely enters the valve seat and blocks the valve seat. At this time, the water flow It can only flow through the drain hole on the valve head, which not only ensures the proper water flow, but also avoids waste caused by excessive flow due to excessive water pressure.

The regulating arm is parallel to the valve stem, so that the cylindrical spring can be stuck between the regulating arm and the valve stem.

When adjusting, inserting the adjustment device with a tool and rotating it can drive the bracket to rotate in the housing, thereby changing the position of the bracket in the housing, thereby adjusting the water output from the water outlet.

The faucet spout is installed on the spout of the faucet for use. The start and stop of the water can be controlled by the switch of the faucet, so the faucet does not need to be removed during adjustment, and the adjustment process will not affect the use of other faucets. In this way, the user can set the maximum water output of each faucet correspondingly according to the different requirements of use.

The above-mentioned embodiments are only used to illustrate and explain the purpose of the present invention, rather than to limit the present invention. Those of ordinary skill in the art may make various changes or substitutions within the essential scope of the present invention, which shall also belong to the present invention. scope of protection for inventions.
