Detailed Description
Referring to fig. 1 to 3, a water pressure regulating device includes a valve seat 100, a valve body 200, a spring 300, a valve core 400, and a valve cover 500.
The valve seat 100 includes a water inlet 110 at the side, a water outlet 120 at the bottom, and a fitting 130 at the top, and an L-shaped cavity 140 as a water flow passage is formed inside. The assembly opening is connected to the valve body 200. Within the valve seat 100 is a water outlet port 150, which is located below the mounting port 200. Referring to fig. 2, in the present embodiment, the water outlet valve port 140 is cylindrical and is disposed at a corner of the L-shaped cavity, and an upper end of the cylinder is higher than a bottom of the L-shaped horizontal cavity.
The water outlet is connected with a waterway device 600, and the waterway device comprises any one of a pressure stabilizing valve, a waterway switch and the like.
The lower end of the valve body 200 is screwed into the assembly opening 200, the valve body 200 is a hollow cylinder with openings at the upper and lower parts, and the interior is an assembly cavity 210.
In another embodiment, the valve seat 100 and the valve body 200 may also be integrally formed.
The upper half part of the valve core 400 is provided with a big end 410 with a cross section larger than that of the core body, the top of the big end 410 is provided with a circular groove 450, the side surface of the big end 410 is provided with a first sealing ring 420, the middle part of the valve core is provided with a second sealing ring 430, and the bottom end of the valve core is sleeved with a sealing gasket 440. The gasket 440 is in a cap shape.
The valve cover 500 includes a water inlet 510 and a water outlet 520, and an internal water flow path 530 is defined between the water inlet 510 and the water outlet 520. Wherein, the water inlet 510 is connected with the waterway device 600, and the water outlet 520 is communicated with the circular groove 450.
The valve core 400 is inserted into the assembly chamber 210 of the valve body and can move up and down along the assembly chamber 210. When the valve core 400 moves to the bottom position, the gasket 400 abuts against the water outlet port 150 to close the water flow passage in the valve seat. The first and second sealing rings 420 and 430 seal the gap between the outer wall of the valve cartridge and the inner wall of the valve body 200, respectively.
The spring 300 has one end abutting on the lower surface of the large end 410 and the other end abutting on the step 220 at the bottom of the assembly chamber 210 of the valve body 200.
The utility model discloses an use as follows:
referring to fig. 2, under normal water pressure, water enters from the water inlet 110, passes through the internal water outlet port 150, and finally flows out from the water outlet 120 to enter the waterway device 600. Wherein, the waterway device 600 has a waterway leading to the water inlet 510 of the valve cover 500; or the water path of the water outlet 120 is divided into two paths, one path enters the water path device 600, and the other path leads to the water inlet 510 of the valve cover 500.
The area from the inlet 110 to the outlet 150 is set to be a high pressure area, and the area from the outlet 150 to the outlet 120 is a low pressure area, with the outlet 150 as a boundary. Since the water outlet 120 and the water inlet 510 are communicated, the valve cover 500 and the area above the large end of the valve core are also low pressure areas.
When the water pressure of the inlet water is greater than a certain set value:
1. the waterway switch (waterway apparatus 600) is turned off.
The pressure in the low pressure chamber rises rapidly, the valve core 400 moves towards the water outlet valve port 150 until the valve core is attached, the spring 300 is compressed, the high pressure area and the low pressure area are separated, and the water path is in a closed state.
2. And opening the waterway switch.
The pressure in the low pressure chamber drops rapidly, the valve core moves away from the water outlet valve port 150 under the action of the high pressure area water pressure and the spring 300, the high pressure area is communicated with the low pressure area, and the water path is in a communicated state.
When the water pressure of inlet water is less than a certain set value
1. Closing the waterway switch.
The pressure generated by the low pressure cavity is insufficient, the valve core does not act, the high pressure area is communicated with the low pressure area, and the water path is in a communicated state.
2. And opening the waterway switch.
The pressure generated by the low-pressure cavity is insufficient, the valve core does not act, the high-pressure area is communicated with the low pressure, and the water way at the front end of the switch is in a communicated state.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
