Description

Technical Field

[0001] This utility model relates to the field of flow valve technology, and in particular to a flow valve that is easy to install. Background Technology

[0002] In fluid control systems, flow valves are key components for regulating medium flow, and their ease of installation directly impacts construction efficiency and maintenance costs. Currently, flow valve installation typically relies on flange alignment, involving manually aligning the mating holes of the valve body flange and the pipe flange before inserting bolts and tightening nuts. However, this process has significant drawbacks: firstly, aligning the flange mating holes requires multiple people, especially in confined spaces, where misalignment can prevent bolt insertion, making the operation cumbersome; secondly, the need to insert and tighten bolts one by one increases the risk of bolts falling out, increasing installation difficulty and safety hazards.

[0003] Therefore, it is necessary to provide a new, easy-to-install flow valve to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a flow valve that is easy to install.

[0005] The easy-to-install flow valve provided by this utility model includes a valve body, on which two liquid guide pipes for liquid inlet and liquid outlet are respectively provided, and flanges are fixedly welded on the liquid guide pipes. Two guide rods fixedly connected to the valve body are fixedly installed on the flanges.

[0006] Both of the liquid guide tubes are fitted with slidingly connected sleeves, and multiple annularly distributed screws are fixedly installed on the sleeves, with each screw corresponding to a mating hole in the flange.

[0007] Two collars are fixedly installed on the socket plate, and the two collars are respectively sleeved on the guide rod and slidably connected to the guide rod. Each guide rod is sleeved with a spring.

[0008] Preferably, one end of the spring is fixedly connected to the outer wall of the valve body, and the other end of the spring is fixedly connected to the inner ring wall of the collar.

[0009] Preferably, U-shaped hooks are fixedly installed on both sides of the socket plate.

[0010] Preferably, locking hooks for hooking onto U-shaped hook brackets are installed on both sides of the valve body.

[0011] Preferably, a side plate is fixedly installed on the side wall of the valve body, and two symmetrically distributed rotating seats are fixedly installed on the side plate. One end of the locking hook is sleeved on the rotating shaft in the rotating seat and rotatably connected to the rotating shaft.

[0012] Preferably, U-shaped limiting frames are fixedly installed on both sides of the liquid guide tube.

[0013] Compared with related technologies, the easy-to-install flow valve provided by this utility model has the following advantages:

[0014] The screws on the socket plate of this utility model correspond one-to-one with the mating holes of the flange, and the sliding cooperation between the guide rod and the collar ensures that the socket plate moves along a fixed trajectory. During installation, the spring force after releasing the lock can automatically push the screw through the mating holes of the valve body flange and the pipe flange, eliminating the need for manual alignment, greatly reducing alignment time and installation difficulty. With the cooperation of the U-shaped hook bracket and the locking hook, the socket plate can be pre-fixed. During installation, only one person needs to complete the initial positioning of the valve body and the pipe, and then release the lock to realize the automatic insertion of the screw, eliminating the need for multiple people to assist or align, reducing manpower requirements.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 4The present invention provides an easy-to-install flow valve, which includes a valve body 1, a sleeve plate 2, and a screw 3.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 4 The valve body 1 is provided with two liquid guide pipes 11 for liquid inlet and liquid outlet respectively, and a flange 12 is fixedly welded to the liquid guide pipe 11. Two guide rods 13 are fixedly installed on the flange 12 and are fixedly connected to the valve body 1. Each of the two liquid guide pipes 11 is fitted with a slidingly connected sleeve plate 2, and multiple annularly distributed screws 3 are fixedly installed on the sleeve plate 2. The screws 3 correspond one-to-one with the mating holes opened in the flange 12. Two collars 21 are fixedly installed on the sleeve plate 2, and the two collars 21 are respectively fitted on the guide rods 13 and slidably connected to the guide rods 13. Each guide rod 13 is fitted with a spring 4. One end of the spring 4 is fixedly connected to the outer wall of the valve body 1, and the other end of the spring 4 is fixedly connected to the inner ring wall of the collar 21.

[0024] Both sides of the socket plate 2 are fixedly installed with U-shaped hook brackets 22. Both sides of the valve body 1 are installed with locking hooks 6 for hooking the U-shaped hook brackets 22. The side wall of the valve body 1 is fixedly installed with a side plate 5, and two symmetrically distributed rotating seats 51 are fixedly installed on the side plate 5. One end of the locking hook 6 is sleeved on the rotating shaft in the rotating seat 51 and rotates and is connected to the rotating shaft.

[0025] It should be noted that before installing the flow valve, the inner sliding sleeve plate 2 drives the collar 21 to compress the spring 4, and then rotates the locking hook 6 to hook the U-shaped hook bracket 22, thus completing the locking of the sleeve plate 2.

[0026] When installing the flow valve, the flanges 12 at both ends of the valve body 1 are aligned with the flanges on the pipeline (ensuring that the mating holes correspond one-to-one). Then, the locking hook 6 is slid out of the U-shaped hook bracket 22. Under the elastic force of the spring 4, the screw 3 is driven through the mating holes on the flanges 12 of the valve body 1 and the pipeline flange. Finally, the nut is used to fix it. The overall operation is simple and convenient.

[0027] In this embodiment, the screws 3 on the socket 2 correspond one-to-one with the mating holes of the flange 12, and the sliding cooperation between the guide rod 13 and the collar 21 ensures that the socket 2 moves along a fixed trajectory. During installation, the spring force of the spring 4 after releasing the lock can automatically push the screw 3 through the mating holes of the valve body flange 12 and the pipe flange, eliminating the need for manual alignment, greatly reducing alignment time and installation difficulty. With the cooperation of the U-shaped hook bracket 22 and the locking hook 6, the socket 2 can be pre-fixed (compressed spring 4 state). During installation, only one person needs to complete the initial positioning of the valve body 1 and the pipe, and then release the lock to realize the automatic insertion of the screw 3, eliminating the need for multiple people to assist or align, thus reducing manpower requirements.

[0028] Furthermore, U-shaped limit frames 14 are fixedly installed on both sides of the liquid guide tube 11. After the valve body 1 is installed, the locking hook 6 hooks onto the U-shaped limit frame 14, thus preventing the locking hook 6 from deflecting arbitrarily.

[0029] In addition, the spring 4 in this application is made of high-strength alloy spring (such as 60Si2Mn material) to improve fatigue resistance. An adjusting nut can also be added to the guide rod 13, and the preload of the spring 4 can be adjusted by rotating the nut to compensate for the decrease in elasticity after long-term use.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
