Description

Technical Field

[0001] This utility model relates to the field of hose valve technology, specifically to quick-install hose valves. Background Technology

[0002] In the world of fluid transport, hose valves play a vital role. They are not only a component of piping systems, but also key to ensuring the safe and efficient transport of fluids.

[0003] However, existing flexible hose valves have certain drawbacks in use. They require modifications to existing pipelines, necessitating pre-installed interfaces or complex modifications, increasing installation difficulty, time, and costs. Furthermore, maintenance and replacement may require cutting the hose, adding to maintenance difficulty, waste, and additional replacement costs. The lack of a symmetrical design leads to uneven stress distribution and localized stress concentration, potentially reducing valve durability and reliability. In the closed state, existing valves cannot clamp the hose securely enough, resulting in poor flow control and potential leakage risks. They are also designed to withstand high pressure within the pipe, especially in situations requiring rapid fluid shut-off, potentially compromising sealing and reliability. Additionally, existing valves intrude into the hose's internal space, affecting its diameter and thus the cross-sectional area for fluid flow, increasing fluid resistance and pressure loss. Direct contact with the liquid inside the hose can increase the risk of valve damage and shorten its lifespan, especially for transporting corrosive liquids. Utility Model Content

[0004] In view of the problems in the prior art, this utility model provides a quick-installation hose valve.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a quick-install hose valve, including a main body, two clamping arms, a crank rod, and an operating rod. The main body is fixed on the hose. Bolts are provided in the middle of the two clamping arms. The two clamping arms are respectively hinged to the two sides of the main body through the bolts in the middle. A clamping cylinder is fixed to the bottom end of the two clamping arms. A connecting rod is hinged to the top of the two clamping arms. The two ends of the crank rod are respectively hinged to the top ends of the two connecting rods. The operating rod is rotatably fitted on the upper part of the main body. An elliptical cam is fixed on the operating rod. The main body of the quick-install hose valve is fixed on the hose. The clamping arms are respectively hinged to the two sides of the main body through the bolts in the middle. The operating rod is rotatably fitted on the upper part of the main body. An elliptical cam is fixed on the operating rod. By rotating the operating rod, the opening and closing of the valve can be quickly controlled, improving the convenience of operation. The design of the operating rod makes the opening and closing control of the valve simple. The user only needs to rotate the operating rod to control the crank rod and clamping arms through the cam, thereby quickly adjusting the on / off state of the hose and improving work efficiency.

[0006] The cam is located directly below the crank and between the two clamping arms. The cam can rotate with the operating lever. This design makes the valve opening and closing faster and more accurate, improving the efficiency of fluid control.

[0007] Preferably, the main body includes two supports, two pipe clamps, and two fixing plates. This compact design reduces the space occupied by the valve, making installation more flexible, especially suitable for space-constrained occasions. The two pipe clamps are fixed to the bottom of the two supports respectively, and the two supports are arranged in a figure-eight pattern. The two fixing plates are vertically fixed to the upper part of the two supports respectively. The two fixing plates are fixed together by bolts, and there is space between the two fixing plates. The crank rod, connecting rod, and cam are all located between the two fixing plates. The centralized layout makes the entire valve structure more compact.

[0008] Preferably, both clamps are circular ring structures, and the diameter of both clamps is adapted to the diameter of the installed hose, so that they can be directly inserted from one end of the hose.

[0009] Preferably, when the cam is in the vertical state, the curved rod is pushed upward by the cam, the lower halves of the two clamping arms are in an open state, the two clamping cylinders are separated from each other, and the hose remains unobstructed. This state keeps the hose unobstructed and allows the fluid to flow without hindrance. When the cam is in the horizontal state, the upper halves of the two clamping arms are撑开 by the cam, the lower halves of the two clamping arms are in a clamping state, the two clamping cylinders pinch the hose flat, and the inside of the hose is in a closed state, effectively cutting off the fluid flow, achieving precise fluid control. By different positions of the cam, precise control of the fluid in the hose can be achieved. Whether in the fully open or fully closed state, it can respond quickly to ensure the accuracy of fluid control. When it is necessary to urgently close or open the fluid, the cooperation of the cam and the operating rod can quickly change the valve state, reducing the response time and improving safety and reliability.

[0010] Preferably, the bottom of the curved rod has a radian. This design helps to disperse the force, reduce wear, and improve the durability of the valve. The cross-section of the clamping cylinder is of a flat-round structure. This structure helps to better clamp the hose and reduce wear during the clamping process.

[0011] Preferably, the operating rod consists of a rotating rod and a rotating handle. The rotating handle is in an inverted "U" shape structure. The two ends of the rotating rod are respectively fixed to the two bottom ends of the rotating handle. The rotating rod and the rotating handle as a whole are in a "mouth" shape structure. The rotating rod passes through the two brackets and two fixing plates of the main body, and the rotating rod is rotationally fitted on the main body. The cam is fixed in the middle of the rotating rod.

[0012] The beneficial effects of the present utility model are as follows:

[0013] (1) For the quick-install hose valve of the present utility model, the valve is fixed outside the hose by two pipe clamps on the main body without changing the existing pipeline, which is especially suitable for situations where it is necessary to temporarily adjust the flow rate or quickly cut off the fluid in an emergency. There is no need to pre-reserve an interface on the pipeline or carry out complex modifications, thus improving the convenience of installation. In addition, since the valve is installed outside the hose, it is not necessary to cut off the hose when maintaining and replacing the valve, which makes the maintenance work more convenient and reduces the maintenance time and cost.

[0014] (2) For the quick-install hose valve of the present utility model, the two clamping arms of the valve are respectively hinged and fitted on both sides of the main body through bolts in the middle, and clamping cylinders are fixed at the bottom ends. When the valve is closed, the lower halves of the two clamping arms are clamped, and the clamping cylinders pinch the hose flat. This symmetrical structural design makes the force more balanced. Connecting rods are hinged at the tops of both clamping arms, and the two ends of the curved rod are respectively hinged to the tops of the two connecting rods. This design makes the force transmission more uniform and reduces local stress concentration. In addition, when the valve is in the closed state, the two long ends of the cam can more stably撑开 the upper parts of the two clamping arms, so that the two clamping cylinders below the two clamping arms can clamp the hose more firmly and tightly, thereby making the throttling effect of the valve better and the valve more capable of withstanding high pressure inside the pipe.

[0015] (3) The quick-install hose valve described in this utility model is installed outside the hose for use. Since the valve is installed outside the hose, it will not intrude into the internal space of the hose. Therefore, when fully open, it will not affect the diameter inside the hose. This means that the cross-sectional area of ​​the fluid flow remains unchanged, thereby ensuring the continuity and efficiency of the fluid flow and reducing fluid resistance and pressure loss. At the same time, since the valve does not directly contact the liquid inside the hose, it is particularly suitable for conveying corrosive liquids. This design reduces the risk of valve damage due to contact with corrosive liquids and extends the service life of the valve.

[0016] (4) The quick-install hose valve of this utility model is fixed to the outside of the hose by two pipe clamps on the main body and the opening and closing effect of the valve is achieved by clamping the hose with two clamps. Since the valve is fixed to the outside of the hose by two pipe clamps on the main body, no destructive modification is required to the hose itself, thus ensuring the integrity and sealing of the hose and avoiding leakage problems that may be caused by installing the valve. In addition, for the transportation of corrosive liquids, the externally installed valve reduces the risk of leakage, because even if the valve fails, the liquid will not directly contact the outside of the valve, thus making the valve safer and more reliable for use in pipelines transporting corrosive liquids.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-6 As shown, the quick-install hose valve of this utility model includes a main body 1, two clamping arms 2, a crank rod 5, and an operating rod 6. The main body 1 is fixed to the hose. Bolts are provided in the middle of the two clamping arms 2, and the two clamping arms 2 are respectively hinged to the two sides of the main body 1 by the bolts in the middle. A clamping sleeve 3 is fixed to the bottom end of the two clamping arms 2, and a connecting rod 4 is hinged to the top of the two clamping arms 2. The two ends of the crank rod 5 are respectively hinged to the top of the two connecting rods 4. The two clamping arms 2 of the valve are respectively hinged to the two sides of the main body 1 by the bolts in the middle, and the clamping sleeve 3 is fixed to the bottom end. When the valve is closed, the lower half of the two clamping arms 2 clamps, and the clamping sleeve 3 flattens the hose. This symmetrical structural design makes the force more balanced. The top of the two clamping arms 2 is hinged to the connecting rod 4, and the two ends of the crank rod 5 are respectively hinged to the top of the two connecting rods 4. This design makes the force transmission more uniform and reduces local stress concentration. In addition, when the valve is closed, the two long ends of the cam 7 can more stably hold the two clamping arms. The upper part of the 2 is spread out, so that the two clamping cylinders 3 below the two clamping arms 2 can clamp the hose more firmly and tightly, thereby improving the valve's shut-off effect and making the valve more resistant to high pressure inside the pipe. The operating rod 6 is rotatably fitted on the upper part of the main body 1. An elliptical cam 7 is fixed on the operating rod 6. The main body 1 of the quick-install hose valve is fixed on the hose. The clamping arms 2 are respectively hinged to both sides of the main body 1 by bolts in the middle. The operating rod 6 is rotatably fitted on the upper part of the main body 1. An elliptical cam 7 is fixed on the operating rod 6. By rotating the operating rod 6, the opening and closing of the valve can be quickly controlled, improving the convenience of operation. The design of the operating rod 6 makes the opening and closing control of the valve simple. The user only needs to rotate the operating rod 6 to control the crank rod 5 and the clamping arms 2 through the cam 7, thereby quickly adjusting the on / off state of the hose and improving work efficiency. The operating rod 6 of this valve can be replaced by a motor. The motor drives the cam 7 to rotate. One-way rotation can quickly switch the on / off state.

[0027] In this design, the cam 7 is located directly below the crank 5 and between the two clamping arms 2. The cam 7 can rotate with the operating lever 6. This design makes the valve opening and closing faster and more accurate, improving the efficiency of fluid control.

[0028] In one optional embodiment of this example, the main body 1 includes two supports 101, two pipe clamps 102, and two fixing plates 103. The main body 1 includes two supports 101, two pipe clamps 102, and two fixing plates 103. This compact design reduces the space occupied by the valve, making installation more flexible, especially suitable for space-constrained occasions. The two pipe clamps 102 are respectively fixed to the bottom of the two supports 101. The two supports 101 are arranged in a figure-eight shape. The two fixing plates 103 are respectively vertically fixed to the upper part of the two supports 101. The two fixing plates 103 are fixed together by bolts, and there is space between the two fixing plates 103. The crank 5, connecting rod 4, and cam 7 are all located between the two fixing plates 103. The centralized layout makes the entire valve structure more compact.

[0029] In one optional embodiment of this invention, both clamps 102 are annular structures, and the diameters of both clamps 102 are adapted to the diameter of the installed hose, allowing them to be directly fitted from one end of the hose. The clamps of the valve can be replaced with side-opening type, which is suitable for industrial control systems where equipment is connected to both ends. It does not need to be fitted from one end of the hose and can be directly installed on the hose. The valve is fixed to the outside of the hose by the two clamps 102 on the main body 1, without changing the existing pipeline. It is particularly suitable for situations where temporary flow adjustment is required or fluid is quickly cut off in an emergency. There is no need to reserve interfaces in the pipeline in advance or make complex modifications, thereby improving the convenience of installation. In addition, since the valve is installed outside the hose, the hose does not need to be cut off when maintaining and replacing the valve, which makes maintenance work more convenient and reduces maintenance time and costs.

[0030] In an alternative embodiment of this example, when the cam 7 is in the vertical state, the curved rod 5 is pushed upward by the cam 7, the lower halves of the two clamping arms 2 are in an open state, the two clamping cylinders 3 are separated, and the hose remains unobstructed. This state keeps the hose unobstructed, allowing the fluid to flow without hindrance; when the cam 7 is in the horizontal state, the upper halves of the two clamping arms 2 are撑开 by the cam 7, the lower halves of the two clamping arms 2 are in a clamped state, the two clamping cylinders 3 flatten the hose, and the inside of the hose is in a closed state, effectively cutting off the fluid flow, achieving precise fluid control. By changing the position of the cam 7, precise control of the fluid inside the hose can be achieved. Whether in the fully open or fully closed state, it can respond quickly to ensure the accuracy of fluid control. When it is necessary to quickly close or open the fluid, the cooperation between the cam 7 and the operating rod 6 can quickly change the valve state, reducing the response time and improving safety and reliability. This valve is installed outside the hose for use. Since the valve is installed outside the hose and does not intrude into the internal space of the hose, it will not affect the inner diameter of the hose in the fully open state. This means that the cross-sectional area of fluid flow remains unchanged, thus ensuring the continuity and efficiency of fluid flow, reducing fluid resistance and pressure loss. At the same time, since the valve does not come into direct contact with the liquid inside the hose, it is especially suitable for transporting corrosive liquids. This design reduces the risk of valve damage caused by contact with corrosive liquids and extends the service life of the valve. This valve is fixed outside the hose using two hose clamps 102 on the main body 1, and the opening and closing effect of the valve is achieved by clamping the hose with the two clamping cylinders 3. Since the valve is fixed outside the hose using two hose clamps 102 on the main body 1, no destructive modifications need to be made to the hose itself, thus ensuring the integrity and sealing of the hose and avoiding leakage problems that may be caused by installing the valve. In addition, for the transportation of corrosive liquids, the externally installed valve reduces the risk of leakage because even if the valve fails, the liquid will not directly contact the outside of the valve, making this valve safer and more reliable when applied to the transportation pipeline of corrosive liquids.

[0031] In an alternative embodiment of this example, the bottom of the curved rod 5 has a curvature, which helps to disperse the force, reduce wear, and improve the durability of the valve. The cross-section of the clamping cylinder 3 is of an oval structure, which helps to better clamp the hose and reduce wear during the clamping process.

[0032] In an alternative embodiment of this example, the operating rod 6 consists of a rotating rod 601 and a rotating handle 602. The rotating handle 602 is of an inverted "U" - shaped structure. The two ends of the rotating rod 601 are respectively fixed to the two bottom ends of the rotating handle 602. The rotating rod 601 and the rotating handle 602 as a whole are of a "square" - shaped structure. The rotating rod 601 passes through the two brackets 101 and the two fixing plates 103 of the main body 1, and the rotating rod 601 is rotationally fitted on the main body 1. The cam 7 is fixed in the middle of the rotating rod 601.

[0033] In use, first, align the body 1 of the quick-connect hose valve with the hose. The body 1 has two clamps 102, which are used to secure the valve to the hose. Place the clamps 102 onto the hose at the appropriate position, ensuring the valve body 1 is aligned with the hose. Secure the clamps 102 to the hose, ensuring the valve body 1 is firmly installed on the outside of the hose. Then, the valve's operating lever 6 rotates and engages with the upper part of the body 1. To open the valve, the operating lever 6 needs to be rotated. When the operating lever 6 rotates, the cam 7, which has an elliptical structure fixed to it, also rotates. The positional change of the cam 7 is transmitted through the crank 5 and connecting rod 4 to the valve body. The clamping arm 2, in turn, affects the position of the clamping cylinder 3. When the cam 7 rotates to the vertical position, the crank rod 5 is pushed upward, the lower half of the clamping arm 2 opens, the clamping cylinder 3 moves away, and the hose remains unobstructed, thus opening the valve. Finally, in order to close the valve, the operating lever 6 needs to be rotated again to change the position of the cam 7. When the cam 7 rotates to the horizontal position, the upper half of the clamping arm 2 is opened by the cam 7, the lower half of the clamping arm 2 is clamped, and the clamping cylinder 3 flattens the hose, putting the hose in a closed state, thus closing the valve. Through a simple rotation of the operating lever 6, precise control of the fluid in the hose can be achieved, and it can respond quickly whether it is fully open or fully closed.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
