Description

Technical Field

[0001] The present invention belongs to the technical field of valve equipment, and particularly relates to a water-saving valve. Background Art

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and regulate and control parameters (temperature, pressure, and flow rate) of the transported medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. A valve is a control component in a fluid transportation system and has functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest stop valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous. However, most of them achieve pipeline opening and closing control by controlling the movement direction of the internal valve flaps. When the fluid flowing in the pipeline is pure liquid, this kind of valve can achieve excellent control effects. But when the liquid flowing in the pipeline is mixed with particulate impurities such as sediment, most valves will have the problem that sediment gets stuck between the internal valve flaps, resulting in difficult opening and closing of the valve or even blockage, which will reduce the control effect and service life of the valve to varying degrees. Summary of the Invention

[0003] To overcome the deficiencies of the prior art, the present invention provides a water-saving valve, and its beneficial effect is that the present invention can maintain normal pipeline opening and closing control effects in pipelines mixed with particulate impurities such as sediment.

[0004] The technical solution adopted by the present invention to solve its technical problems is:

[0005] A water-saving valve includes two connecting pipe heads. A deformable pipe is hermetically and detachably connected between the two connecting pipe heads. A clamping structure is sleeved on the deformable pipe, and the clamping structure is installed inside the two connecting pipe heads. A driving structure is sleeved on the clamping structure. Rotating the driving structure can drive the clamping structure to squeeze the deformable pipe.

[0006] The clamping structure includes two clamping wheel hoops, which are respectively fixedly connected to the inner sides of the two connecting pipe heads. Three sets of extrusion sheets are rotatably connected between the two clamping wheel hoops. The three sets of extrusion sheets are staggered by 15° in the clockwise direction in turn, and the driving structure is sleeved on the two clamping wheel hoops.

[0007] The extrusion sheet includes five rotating rods. An adjusting blade is rotatably connected to the rotating rod. The inner end of the adjusting blade is in contact with the deformable pipe, and the outer end of the adjusting blade is cooperatively connected with the clamping structure. The five rotating rods are uniformly and circumferentially fixedly connected between the two clamping wheel hoops.

[0008] Two fixing buckles are arranged on the rotating rod, the adjusting blade in the first group of extrusion sheets is located between the clamping wheel hoop on the left and the fixing buckle on the left, the adjusting blade in the second group of extrusion sheets is located between the two fixing buckles, and the adjusting blade in the third group of extrusion sheets is located between the fixing buckle on the right and the clamping wheel hoop on the right.

[0009] The driving structure includes a rotating ring, which is fixed between a rotating left ring and a rotating right ring. The rotating left ring and the rotating right ring are respectively rotatably connected to two clamping wheel hoops. A plurality of blade openings are formed between the rotating left ring and the rotating right ring. The outer end of the adjusting blade passes through the blade opening. The outer end of the adjusting blade is located in a space formed by the rotating left ring, the rotating right ring and the rotating ring.

[0010] The outer end of the adjusting blade is fixedly connected with a toggle rod, the inner end of the adjusting blade and the inner end of the toggle rod are both arc-shaped surfaces, and the arc-shaped surface inside the toggle rod fits with the outer side surface of the circular ring formed by rotating the left ring and the right ring.

[0011] A circle of high-strength wear-resistant metal is arranged on the arc surface of the inner end of the adjusting blade.

[0012] An annular fixing plate for fastening the deformation tube is fixedly connected to the middle of the inner wall of the connecting pipe head, and a threaded portion for connecting with a water pipe is arranged at the outer end of the connecting pipe head.

[0027] As Figures 1 to 3 shown:

[0028] The water-saving valve includes two connecting pipe heads 110. A deformation pipe 120 is hermetically and detachably connected between the two connecting pipe heads 110. A clamping structure is sleeved on the deformation pipe 120. The clamping structure is installed inside the two connecting pipe heads 110. A drive structure is sleeved on the clamping structure. Rotating the drive structure can drive the clamping structure to squeeze the deformation pipe 120, so that the deformation pipe 120 is squeezed and converges and deforms inward, thereby achieving the effect of closing the pipeline; since it is the pipeline itself that generates deformation, there are no gaps or corners that are prone to accumulating particulate matter, so there will be no jamming phenomenon caused by the particulate matter contained in the liquid flowing through the pipeline. After the deformation is restored, the accumulated particulate matter will directly flow away along the pipeline normally. At the same time, by repeatedly squeezing the deformation pipe 120 to generate deformation, when the water-saving valve is reopened after being closed for a long time, the position of the semi-dry retained particulate matter can also be moved, so that it is easily driven away by the fluid and the pipeline is kept unobstructed.

[0029] As Figure 4 and Figure 5 shown:

[0030] The clamping structure includes two clamping wheel hoops 130. The two clamping wheel hoops 130 are respectively welded inside the two connecting pipe heads 110. Three groups of extrusion sheets are rotatably connected between the two clamping wheel hoops 130. The three groups of extrusion sheets are staggered by 15° in the clockwise direction in turn. The drive structure is sleeved on the two clamping wheel hoops 130;

[0031] When the pipeline needs to be closed, a single group of extrusion sheets squeezes the deformation pipe 120. The force-bearing area is too small, which easily causes the force on the deformation pipe 120 to be too concentrated along the circumferential direction of the deformation pipe 120 per unit area and cause damage. However, multiple groups of staggered extrusion sheets squeeze the deformation pipe 120 at the same time, which can increase the force-bearing area of the deformation pipe 120 and increase the deformation area of the deformation pipe 120.

[0032] Furthermore:

[0033] There are two fixing buckles 132 provided on the rotating rod 131. Among the first group of pressing pieces, the adjusting blade 140 is located between the clamping wheel hoop 130 on the left and the fixing buckle 132 on the left. Among the second group of pressing pieces, the adjusting blade 140 is located between the two fixing buckles 132. Among the third group of pressing pieces, the adjusting blade 140 is located between the fixing buckle 132 on the right and the clamping wheel hoop 130 on the right. The three groups of pressing pieces are staggered, enabling the force-bearing areas on the deformation tube 120 to be evenly distributed along the axial direction of the deformation tube 120, avoiding damage to the deformation tube 120 due to pressure and extending the service life of the water-saving valve at the same time.

[0034] As Figure 6 shown:

[0035] The pressing piece includes five rotating rods 131. An adjusting blade 140 is rotatably connected to the rotating rod 131. The inner end of the adjusting blade 140 is in contact with the deformation tube 120, and the outer end of the adjusting blade 140 is connected to the clamping structure in a matching manner. The five rotating rods 131 are evenly and fixedly connected in a surrounding manner between the two clamping wheel hoops 130;

[0036] Under normal conditions, when the pipeline needs to be closed, by rotating the driving structure, the adjusting blade 140 rotates around the rotating rod 131, causing the inner end of the adjusting blade 140 to move towards the center of the deformation tube 120, thereby squeezing the deformation tube 120 and deforming the deformation tube 120 to achieve the purpose of closing the pipeline. Secondly, multiple adjusting blades 120 evenly distributed in the circumferential direction rotate simultaneously, enabling the force deformation of each part of the deformation tube 120 to be uniform and extending the service life of the deformation tube 120.

[0037] As Figure 7 and Figure 8 shown:

[0038] The driving structure includes a rotating ring 150. The rotating ring 150 is welded between the rotating left ring 151 and the rotating right ring 152. The rotating left ring 151 and the rotating right ring 152 are respectively rotatably connected to the two clamping wheel hoops 130. A plurality of blade through openings 153 are formed between the rotating left ring 151 and the rotating right ring 152. The outer end of the adjusting blade 140 passes through the blade through opening 153, and the outer end of the adjusting blade 140 is located in the space formed by the rotating left ring 151, the rotating right ring 152 and the rotating ring 150; when installing the adjusting blade 140, it can only be installed at the position corresponding to the rotating rod 131 and the blade through opening 153, and the adjusting blade 140 is limited by the fixing buckle 132 on the rotating rod 131 and the blade through opening 153 to prevent the adjusting blade 140 from flipping under the lateral force or moving axially during rotation.

[0039] As Figure 8 and Figure 9 shown:

[0040] A shifting rod 141 is welded to the outer end of the adjusting vane 140. The inner end of the adjusting vane 140 and the inner side of the shifting rod 141 are arc-shaped surfaces. The arc-shaped surface on the inner side of the shifting rod 141 is in contact with the outer side surface of the circular ring formed by the rotating left ring 151 and the rotating right ring 152. When the shifting rod 141 is driven by the vane through-hole 153 to rotate, the arc-shaped surface of the shifting rod 141 can completely adhere to the outer side of the inner layer of the rotating ring 150, so that the adjusting vane 140 can maintain stability during rotation.

[0041] Furthermore:

[0042] A circle of high-strength wear-resistant metal is provided on the arc-shaped surface at the inner end of the adjusting vane 140. While ensuring the extrusion effect of the adjusting vane 140, it can reduce the wear of the adjusting vane 140 on the deformation tube 120.

[0043] As Figure 10 shown:

[0044] An annular fixing piece 111 for fastening the deformation tube 120 is welded to the middle of the inner wall of the connecting pipe head 110. A threaded portion 112 for connecting with a water pipe is provided at the outer end of the connecting pipe head 110;

[0045] Under normal conditions, both ends of the deformation tube 120 are respectively placed between the inner wall of the two connecting pipe heads 110 and the annular fixing piece 111 and clamped and fixed, so that the inside of the water-saving valve can be kept as smooth as possible, and there are no positions such as flanges or depressions that are likely to accumulate sediment. The threads 112 on the outer sides of the two connecting pipe heads 110 are connected to the water pipe heads to be connected, and the water-saving valve can be completely connected to the pipeline, which is convenient for disassembly at any time.

[0046] As Figure 11 and Figure 12 shown:

[0047] An L-shaped buckle 113 for fastening the deformation tube 120 is provided at the inner end of the annular fixing piece 111. L-shaped grooves 114 matching the L-shaped buckle 113 are provided at both ends of the deformation tube 120. When the deformation tube 120 is installed, the deformation tube 120 is placed between the inner wall of the connecting pipe head 110 and the annular fixing piece 111, and the annular fixing piece 111 is expanded and clamped. The L-shaped buckle 113 can be embedded inside the L-shaped groove 114, so that the deformation tube 120 will not slip due to the deformation during extrusion.

[0048] Furthermore:

[0049] The deformation tube 120 is made of high-elasticity wear-resistant rubber to provide sufficient deformation to close the pipeline.
