Abstract
Description
Technical Field
[0001] This invention relates to the field of water supply and drainage, and in particular to a quick-connect water pump valve. Background Technology
[0002] The water pump control valve is a multi-functional valve that uses a pilot-operated method to control flow. It is suitable for water distribution pipelines where flow and pressure need to be controlled, maintaining a predetermined flow rate, limiting excessive flow to a predetermined value, and appropriately reducing upstream high pressure. Even if the pressure upstream of the main valve changes, it will not affect the flow rate downstream of the main valve.
[0003] Due to environmental protection requirements, a large amount of wastewater used in the mine needs to be purified and recycled. Because there is a lot of dust and slag in the mine, even if filtered through a filter screen, a lot of dust will adhere to the filter screen, which will seriously affect the filtration efficiency. At this time, some dust enters the water pump valve, which can easily cause wear to the water pump valve, thereby affecting the sealing performance of the water pump valve. Therefore, the staff needs to maintain the water pump valve regularly and replace the filter screen. However, the disassembly and assembly of the water pump valve is complicated, which makes each maintenance take a lot of time. Summary of the Invention

[0032] Example 1
[0033] Reference Figure 1-5 This embodiment provides a quick-connect water pump valve, including a connecting assembly 100, comprising an inlet pipe 101, a rotating sleeve 102 fitted onto the inlet pipe 101, and the inlet pipe 101 connected to a water pump valve interface 103; a filter screen 101a is provided at the inlet of the inlet pipe 101, and a locking groove 101b, a connecting plate 101c, and a sliding groove 101d are sequentially provided on the outer wall of the inlet pipe 101; the connecting plate 101c has symmetrical openings 101c-1, and the openings 101c-1 have a first positioning surface 101c-2 and a second positioning surface 101c-3; the sliding groove 101d includes an inclined groove 101d-1 and a straight groove 101d-2; the rotating sleeve 102... The inner wall of the 02 is symmetrically provided with limiting posts 102a, and the outer side of the rotating sleeve 102 is provided with a rotating plate 102b. The rotating plate 102b is symmetrically provided with an arc groove 102b-1, and the arc groove 102b-1 is provided with a locking tongue 102c. The end face of the water pump valve interface 103 is symmetrically provided with a slot 103a, which is connected to the lifting chamber 103b. The lifting chamber 103b is provided with a pin 103c, and the pin 103c is provided with a locking hole 103c-1. The bottom of the pin 103c is provided with a lifting spring 103c-2. The side wall of the pin 103c is symmetrically provided with a limiting block 103c-3. The inner wall of the water pump valve interface 103 is provided with a spiral blade 103d.
[0034] Specifically, the filter screen 101a is detachably connected to the water inlet pipe 101. The filter screen 101a is made of flexible material, and it will deform when water flows and impacts it.
[0035] Preferably, the latch 102c is telescopic, and the side wall of the latch 102c is provided with a limiting member. The limiting member is fixed to the side wall of the arc groove 102b-1 to prevent the latch 102c from tilting. The diameter of the latch 102c is the same as the diameter of the lock hole 103c-1, and the width of the slot 103a is also the same as the diameter of the latch 102c. The limiting block 103c-3 can be embedded in the side wall of the lifting chamber 103b, so that the pin 103c can move up and down in the lifting chamber 103b.
[0036] Furthermore, the outer wall of the rotating sleeve 102 is provided with a toggle block, which makes it easier to rotate; the limiting post 102a is embedded in the slide groove 101d, and the rotating sleeve 102 can be driven to move along the slide groove 101d through the limiting post 102a, and the arc groove 102b-1 is a shape that gradually moves away from the center.
[0037] Furthermore, one end of the pin 103c is provided with a bevel. When the water inlet pipe 101 is inserted into the water pump valve interface 103, the water inlet pipe 101 contacts the bevel and pushes the pin 103c into the lifting chamber. After the water inlet pipe 101 is fully connected to the water pump valve interface 103, the pin 103c is pushed out by the lifting spring 103c-2, so that the bevel is inserted into the locking groove 101b, thus completing the fixed connection between the water inlet pipe 101 and the water pump valve interface 103.
[0038] Furthermore, when the inlet pipe 101 is connected to the water pump valve interface 103, the opening 101c-1 communicates with the slot 103a, and the first positioning surface 101c-2 coincides with the side wall of the slot 103a; the included angle formed by the first positioning surface 101c-2 and the second positioning surface 101c-3 is consistent with the angle swept by the arc length of the arc groove 102b-1. When the limiting post 102a moves to the end of the inclined groove 101d-1, the rotating sleeve 102 is just in close contact with the surface of the connecting plate 101c. At this time, the first positioning surface 101c-2 and the... The distance from the endpoint of the arc groove 102b-1 near the center is exactly equal to the diameter of the bolt 102c. By limiting the first positioning surface 101c-2, no matter where the bolt 102c is in the arc groove 102b-1, by rotating the rotating sleeve 102, the bolt 102c will eventually move to the position near the center of the arc groove 102b-1. Setting the first positioning surface 101c-2 can realize the positioning of the bolt 102c, ensuring that the bolt 102c is accurately inserted into the lock hole 103c-1, and completing the limiting of the pin 103c.
[0039] In this embodiment, the inlet pipe 101 and the water pump valve interface 103 are fixed by a pin 103c. Since the filter screen 101a inside the inlet pipe 101 needs to be replaced after a period of use, it can be unlocked by rotating the sleeve 102. When rotating the sleeve 102, the limiting post 102a first moves along the inclined groove 101d-1, driving the sleeve 102 closer to the connecting plate 101c, and extending the locking tongue 102c into the opening 101c-1. When the limiting post 102a moves to the end of the inclined groove 101d-1, the sleeve 102 and the connecting plate 101c are completely pressed together, and the locking tongue 102c passes through the slot 103a and is inserted into the lock hole 103c-1. At this time, when rotating the sleeve 102 in the opposite direction, the limiting post 102a enters the straight groove 101. Inside d-2, since the locking tongue 102c is locked when it is inserted into the lock hole 103c-1, the rotating sleeve 102 will drive the locking tongue 102c to move along the arc groove 102b-1 when it rotates. As the arc groove 102b-1 gradually moves away from the center, the locking tongue 102c will move away from the water inlet pipe 101. The movement of the locking tongue 102c will drive the pin 103c to retract into the lifting chamber 103b. At this time, the water inlet pipe 101 and the water pump valve interface 103 can be disassembled, thereby completing the replacement of the filter screen 101a.
[0040] The locking tongue 102c can be positioned by the first positioning surface 101c-2 to ensure that the locking tongue 102c is accurately inserted into the lock hole 103c-1 and to lock the pin 103c. This ensures accurate connection while enabling quick connection. By setting the connecting component 100, the water inlet pipe 101 and the water pump valve can be quickly connected and disassembled, which is convenient for staff to maintain the water pump valve and replace the filter screen, thus improving work efficiency.
[0041] Example 2
[0042] Reference Figure 6-7This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that: the control component 200 includes a valve body 201 connected to the water pump valve interface 103, a valve stem 202 is provided inside the valve body 201, and a diaphragm pressure plate 203, a slow-closing valve disc 204, a main valve disc 205 and a rotating component 206 are sequentially sleeved on the valve stem 202; a valve seat 201a is provided inside the valve body 201, and a partition plate 201b is also provided inside the valve body 201; both the inlet and outlet of the valve body 201 are provided with diversion pipes 201c; one end of the valve stem 202 is provided with an external thread 202a; the diaphragm pressure plate 203 includes an upper mold pressure plate 203a, a diaphragm 203b and a lower mold pressure plate 203c; the slow-closing valve disc... 204 is slidably connected to valve stem 202. A spring 204a is provided between slow-closing valve disc 204 and partition plate 201b. Slow-closing sealing plate 204b is provided at the lower end of slow-closing valve disc 204. A bushing 205a is provided on main valve disc 205. Bushing 205a is slidably connected to valve stem 202. A drain plate 205b is provided in the middle of main valve disc 205. Drain holes 205b-1 are provided on the upper ring of drain plate 205b. Sealing plate 205c is provided at the bottom of main valve disc 205. Rotating component 206 includes fixed ring 206a and fan blade 206b. Fixed ring 206a is fixedly connected to valve seat 201a. Connecting sleeve 206c is provided on fan blade 206b. Thread 206c-1 is provided on the inner wall of connecting sleeve 206c.
[0043] Specifically, the valve body 201 is divided into a flow chamber and a control chamber by a partition 201b. The diaphragm pressure plate 203 is placed in the control chamber, and the other parts are placed in the flow chamber. The control chamber is further divided into upper and lower parts. The diversion pipe 201c on the inlet side is connected to the lower control chamber, and the diversion pipe 201c on the outlet side is connected to the upper control chamber. The diaphragm 203b is made of flexible material and can be bent at will.
[0044] Preferably, when the slow-closing valve disc 204 is in close contact with the main valve disc 205, it is sealed by the slow-closing sealing plate 204b to prevent water from flowing through the gap; when the main valve disc 205 is in close contact with the valve seat 201a, it is sealed by the sealing plate 205c.
[0045] Furthermore, the external thread 202a on the valve stem 202 engages with the thread 206c-1 on the connecting sleeve 206c. Since the valve stem 202 can only move up and down, when the valve stem 202 is inserted into the connecting sleeve 206c, the engagement of the external thread 202a and the thread 206c-1 can drive the fan blade 206b to rotate.
[0046] In this embodiment, after the inlet pipe 101 is connected to the water pump valve interface 103, the water flowing out of the inlet pipe 101 enters the valve body 201. The water pressure pushes the main valve disc 205, which in turn drives the slow-closing valve disc 204 to rise and compresses the spring 204a. At the same time, a portion of the water from the inlet enters the lower control chamber from the diversion pipe 201c. As water continuously flows into the lower control chamber, it pushes the lower molding plate 203c to rise. The rise of the lower molding plate 203c drives the valve stem 202 to rise, further driving the main valve disc 205 and the slow-closing valve disc 204 to rise. At this time, water can enter the flow chamber and flow out from the outlet of the valve body 201. When the valve of the inlet pipe 101 is closed or the water... When the flow decreases, the weight of the main valve disc 205 is greater than the water pressure, causing the main valve disc 205 to descend and press against the valve seat 201a, blocking most of the water flow into the flow chamber. Since the water pressure at the inlet of the valve body 201 is less than the water pressure at the outlet, the flow rate in the branch pipe 201c at the outlet is greater than the flow rate in the branch pipe 201c at the inlet. The water pressure in the upper control chamber is greater than the water pressure in the lower control chamber, which can push the diaphragm plate 203 downward. The downward movement of the diaphragm plate 203 will drive the valve stem 202 downward. Through the push of the spring 204a, the slow-closing valve disc 204 will accelerate downward, while pushing some water back to the inlet of the valve body 201. Finally, the slow-closing valve disc 204 will press against the main valve disc 205, preventing water flow.
[0047] The control component 200 can monitor water pressure in real time. When the water pressure decreases or there is no water flow, the water pump valve can be closed to control the water flow.
[0048] Example 3
[0049] Reference Figure 1-8 This is the third embodiment of the present invention. This embodiment provides a quick-connect water pump valve. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: the water pump valve interface 103 has a slot 103a symmetrically provided on its end face. The slot 103a is connected to the lifting chamber 103b. The lifting chamber 103b is provided with a pin 103c. The pin 103c has a locking hole 103c-1. The bottom of the pin 103c is provided with a lifting spring 103c-2. The side wall of the pin 103c is symmetrically provided with a limiting block 103c-3. The inner wall of the water pump valve interface 103 is provided with a spiral blade 103d. The rotating component 206 includes a fixing ring 206a and a fan blade 206b. The fixing ring 206a is fixedly connected to the valve seat 201a. The fan blade 206b is provided with a connecting sleeve 206c. The inner wall of the connecting sleeve 206c is provided with a thread 206c-1.
[0050] Specifically, when water flows in through the inlet pipe 101, the water pressure causes the filter screen 101a to bulge outward; the inner wall of the water pump valve interface 103 is provided with a slope. When the valve body 201 experiences backflow, the slope reduces the pipe diameter, thereby increasing the backflow velocity. The impact of the backflow water causes the filter screen 101a to concave inward, which can remove the impurities attached to the filter screen 101a and achieve the cleaning of the filter screen 101a.
[0051] Furthermore, the pump valve interface 103 is also provided with a spiral blade 103d. When the return water passes through the spiral blade 103d, it can rotate and increase the flow rate, thereby increasing the pressure of the return water impacting the filter screen 101a, and further improving the cleaning efficiency of the filter screen 101a.
[0052] Furthermore, when the valve stem 202 descends, the fan blade 206b can rotate by engaging the external thread 202a with the thread 206c-1 of the connecting sleeve 206c, thereby increasing the flow rate of the return water.
[0053] By setting the rotating part 206 and the water pump valve interface 103, the flow rate of the return water can be greatly increased, thereby increasing the impact force of the return water on the filter screen 101a, removing the impurities attached to the filter screen 101a, realizing the self-cleaning of the filter screen 101a, and improving the service life of the filter screen 101a.
