Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a water-saving valve with dual control switches and high sealing performance. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, and their types and specifications are quite numerous.

[0003] Most existing valves use a single control mechanism, which wears down over time. This leads to poor sealing, causing water to leak and wasting water resources. Furthermore, due to prolonged use, gaps may appear between the valve's control screw and the valve's center line when the valve is open, allowing liquid or gas leakage and resulting in poor sealing. Utility Model Content

[0004] The purpose of this invention is to provide a water-saving valve with dual control switches and high sealing performance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-saving valve with dual control switches and high sealing performance, comprising a valve tube and a spring. A valve seat is connected to the middle of the outer surface of the top end of the valve tube, and a handle is provided on the outer surface of the top end of the valve seat. A filter screen is attached to the inner wall of the water inlet end of the valve tube. Dividing blocks are symmetrically arranged inside the valve tube below the valve seat, and the dividing blocks are arc-shaped. A through hole is provided at the connection between the dividing blocks. An installation ring is attached to the inner wall of the valve tube near the water outlet end, and the installation ring is sealed to the inner wall of the valve tube.

[0006] Preferably, a rotating rod is connected to the bottom outer surface of the handle, and one end of the rotating rod passes through the valve seat and is installed inside the top of the valve tube. The outer surface of the rotating rod near the top of the valve seat is provided with a thread, and a nut block is connected through the outer surface of the thread. The edge of the nut block is embedded in the inside of the valve seat.

[0007] The above technical solution enables the handle to rotate, which in turn drives the rotating rod to rotate, thereby causing the rotating rod to rise and fall.

[0008] Preferably, a sealing gasket is connected to one end of the rotating rod located inside the top of the valve tube, a sealing block is horizontally arranged in the cavity inside the top of the valve tube, and the edge of the sealing block is in close contact with the inner wall of the valve seat, and an annular groove is provided at the middle position of the bottom outer surface of the sealing block.

[0009] The above technical solution connects the rotating rod to the sealing gasket, rather than penetrating it, thus eliminating gaps between the sealing gasket and the rotating rod and resulting in high sealing performance.

[0010] Preferably, a connecting rod is connected to the middle position of the end of the sealing gasket away from the rotating rod, a sealing strip is embedded at the outer edge of the sealing gasket near the sealing block, and the outer surface of the sealing strip corresponds to the inner wall of the slot, and a piston is connected to the bottom end of the connecting rod, while the outer surface of the piston is in contact with the inner wall of the through hole provided at the middle connection of the partition block;

[0011] The above technical solution ensures that the sealing strip fits snugly against the groove, guaranteeing overall sealing performance.

[0012] Preferably, a cavity block is fitted inside the mounting ring, and the outer surface of the cavity block is fitted with the inner wall of the mounting ring. The cavity block is spherical, and a circular hole is provided through the outer surfaces of both sides of the cavity block. A sealing plug is provided inside the side of the circular hole near the valve tube, and the edge of one side of the outer surface of the sealing plug is fitted with the edge of the circular hole.

[0013] The above technical solution enables the sealing plug to block one side of the cavity block, preventing water that has seeped into the upper part of the piston from flowing out of the valve pipe and improving the sealing performance.

[0014] Preferably, a compression rod is symmetrically arranged on the other outer surface of the sealing plug, a rectangular limiting plate is longitudinally arranged inside the cavity block, one end of the compression rod penetrates one outer surface of the limiting plate, and a spring is sleeved on the outer surface of the compression rod between the limiting plate and the sealing plug.

[0015] The above technical solution allows water to quickly enter the front end of the cavity block after the piston is opened. Due to the pressure, the sealing plug is compressed by the spring, which causes the sealing plug to separate from the cavity block, allowing water to flow out from the valve pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this water-saving valve has a dual control switch and high sealing performance.

[0017] 1. It is equipped with a sealing gasket and a sealing strip. The sealing strip is embedded in the edge of the sealing gasket. When the rotating rod rotates and rises, it drives the sealing gasket and sealing strip to rise at the same time, so that the sealing strip is engaged into the inside of the groove. This prevents water from overflowing from the gap between the rotating rod and the center line of the sealing block when it flows through, thus improving its overall sealing performance.

[0018] 2. Equipped with a sealing plug and spring, when the piston's sealing performance deteriorates, a small amount of water slowly overflows to the top of the piston. At this time, due to the action of the sealing plug, the water is blocked a second time, thus preventing water from being discharged directly from the outlet of the valve pipe. At the same time, when the piston is fully opened, the water pressure pushes against the sealing plug, causing it to compress and open the round hole, allowing water to flow out. This makes the overall sealing and protection more effective and has a certain water-saving function.

[0019] 3. The rotating rod does not pass directly through the sealing gasket and the piston, but is connected by a connecting rod, so that there is no gap in the middle of the sealing gasket, thereby enhancing the overall sealing performance and preventing water from overflowing. At the same time, a filter screen is installed to filter the water entering the valve pipe, preventing impurities from clogging the internal groove and affecting the overall sealing performance.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a water-saving valve with dual control switches and high sealing performance, including a valve pipe 1, a valve seat 2, a handle 3, a rotating rod 4, a thread 5, a nut block 6, a sealing block 7, a groove 8, a sealing gasket 9, a sealing strip 10, a connecting rod 11, a piston 12, a partition block 13, a filter screen 14, a mounting ring 15, a cavity block 16, a round hole 17, a sealing plug 18, a compression rod 19, a spring 20, and a limiting plate 21. The valve seat 2 is connected to the middle position of the outer surface of the top end of the valve pipe 1, and the handle 3 is provided on the outer surface of the top end of the valve seat 2. The filter screen 14 is attached to the inner wall of the water inlet end of the valve pipe 1. The valve pipe 1 is located below the valve seat 2 and has symmetrically arranged partition blocks 13. The partition blocks 13 are arc-shaped and have through holes at the connection between the partition blocks 13. An installation ring 15 is fitted into the inner wall of the valve pipe 1 near the outlet end and is sealed to the inner wall of the valve pipe 1. When the valve pipe 1 is opened, the handle 3 is turned first, which causes the rotating rod 4 and the connecting rod 11 to drive the piston 12 to rise simultaneously. This opens the through hole between the partition blocks 13. At the same time, when the rotating rod 4 rises, it causes the sealing strip 10 at the upper end of the sealing gasket 9 to engage with the groove 8, which improves the sealing performance. Water enters the upper part of the partition block 13 through the through hole and flows to the front end of the sealing plug 18. Due to the water pressure, the sealing plug 18 is pushed open, and water flows from the inside of the cavity block 16 to the outlet of the valve pipe 1.

[0027] A rotating rod 4 is connected to the bottom outer surface of the handle 3, and one end of the rotating rod 4 passes through the valve seat 2 and is installed inside the top of the valve pipe 1. A thread 5 is provided on the outer surface of the rotating rod 4 near the top of the valve seat 2, and a nut block 6 is connected through the outer surface of the thread 5. The edge of the nut block 6 is embedded inside the valve seat 2. A sealing gasket 9 is connected to the end of the rotating rod 4 inside the top of the valve pipe 1. A sealing block 7 is horizontally arranged in the cavity inside the top of the valve pipe 1, and the edge of the sealing block 7 is fitted against the inner wall of the valve seat 2. A ring-shaped groove 8 is provided at the middle position of the bottom outer surface of the sealing block 7. A connecting rod 11 is connected to the middle position of the end of the sealing gasket 9 away from the rotating rod 4. A sealing strip 10 is embedded in the outer edge of the sealing gasket 9 near the sealing block 7, and the outer surface of the sealing strip 10 corresponds to the inner wall of the slot 8. A piston 12 is connected to the bottom end of the connecting rod 11, and the outer surface of the piston 12 is in contact with the inner wall of the through hole in the middle of the partition block 13. When the rotating rod 4 is rotated and raised, the sealing strip 10 at the upper end of the sealing gasket 9 is driven to rise, thereby engaging with the slot 8 at the lower end of the sealing block 7. This prevents water from overflowing from the gap between the rotating rod 4 and the sealing block 7, thus ensuring high overall sealing performance.

[0028] A cavity block 16 is fitted inside the mounting ring 15, and the outer surface of the cavity block 16 is fitted to the inner wall of the mounting ring 15. The cavity block 16 is spherical, and circular holes 17 are provided through the outer surfaces of both sides of the cavity block 16. A sealing plug 18 is provided inside the side of the circular hole 17 closest to the valve pipe 1, and the edge of one side of the outer surface of the sealing plug 18 is fitted to the edge of the circular hole 17. A compression rod 19 is symmetrically arranged on the other side of the outer surface of the sealing plug 18. A rectangular limiting plate 21 is longitudinally arranged inside the cavity block 16, and one end of the compression rod 19 passes through one side of the limiting plate 21. The outer surface of the compression rod 19 between the limiting plate 21 and the sealing plug 18 is fitted with a spring 20. When the piston 12 rises, the through hole provided at the middle connection of the partition block 13 opens, allowing water to flow to the upper end of the partition block 13, thereby allowing water to flow to the front end of the sealing plug 18. Through the pressure of the water, the sealing plug 18 is squeezed, causing the sealing plug 18 and the compression rod 19 to be compressed towards the outlet of the valve pipe 1 by the compression of the spring 20, thereby causing the sealing plug 18 to separate from the edge of the round hole 17 inside the cavity block 16, thereby allowing water to flow into the interior of the cavity block 16, and finally to the outlet of the valve pipe 1.

[0029] Working principle: When using this water-saving valve with dual control switches and high sealing performance, firstly... Figure 1-4As shown, when the sealing performance of piston 12 deteriorates, a small amount of water will overflow to the top of piston 12 and flow to the front end of cavity block 16. However, due to the low water pressure, the sealing plug 18 will not detach from the edge of the round hole 17 inside cavity block 16, thus preventing water from flowing out and playing a secondary control sealing role. Meanwhile, compression rod 19, spring 20 and limit plate 21 are all made of stainless steel and coated with rust inhibitor on the outer surface, making the whole structure less prone to rusting, extending service life and increasing overall practicality.
