Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a hydraulic tooling for a three-way valve. Background Art

[0002] The hydraulic pressure test of a three-way valve tests the valve's sealing and pressure resistance under a certain pressure. This testing process ensures that the valve can withstand certain water pressure shocks and external environmental changes before use, ensuring safe and stable operation in actual applications. The process of the three-way valve hydraulic pressure test mainly includes a static hydraulic pressure test. The static hydraulic pressure test applies a certain amount of water pressure inside the valve after closing it. The test verifies the sealing and pressure resistance of the valve by detecting water leakage, thereby evaluating the valve's performance.

[0003] The outlet of a current three-way valve is typically machined into a flange with several circular holes. A blind flange is aligned with the three-way valve flange, then screws are inserted to secure it, blocking the outlet and closing the valve. This type of three-way valve is inefficient when machining flanges because it requires drilling holes in the flange end face, adding another hole after each one, until all holes on the flange are machined. Furthermore, the flange, as the connection to the blind flange, is very susceptible to damage. Damage necessitates replacing the entire three-way valve, resulting in significant waste.

[0004] Therefore, the existing technology needs to be improved. Utility Model Content

[0005] The technical problem to be solved by the present invention is that the flange drilling processing efficiency of the three-way valve in the prior art is low, and the replacement cost of the flange after damage is high. The purpose is to provide a hydraulic tooling for the three-way valve, which adopts corresponding technical means and has the beneficial effects of high processing efficiency, convenient repair after damage, and low repair cost.

[0006] The utility model is achieved through the following technical solutions:

[0007] The utility model provides a hydraulic tool for a three-way valve, which comprises a valve body, wherein the valve body is provided with a pipe mouth, the pipe mouth sleeve is provided with a detachably connected clamp, the port of the pipe mouth is provided with a flange blind plate, and the flange blind plate is provided with a fixing piece fixedly connected to the clamp.

[0008] In the above technical solution, before conducting a water pressure test, the clamp is fixedly connected to the pipe mouth of the valve body, and then the flange blind plate and the clamp are fixedly connected through a fixing piece. After the flange blind plate is fixed, the port of the pipe mouth is sealed to prevent liquid leakage. The detachable clamp replaces the flange on the original three-way valve, so there is no need to drill holes on the three-way valve, which greatly reduces the processing time of the three-way valve and improves the processing efficiency and production efficiency of the three-way valve. In addition, the clamp is used to replace the flange and flange blind plate connection on the original three-way valve. If the clamp is damaged, it can be directly removed and replaced without replacing the entire three-way valve, which is convenient for maintenance and has low maintenance costs.

[0009] Furthermore, in the present invention, the end of the pipe opening is provided with an outer edge that blocks the clamp.

[0010] Furthermore, in the present invention, the pipe opening adjacent to the pipe opening where the flange blind plate is installed is provided with a plug.

[0011] Furthermore, in the present invention, the fixing member includes a screw, the flange blind plate is provided with a mounting hole for the screw to pass through, and the screw is threadedly connected with a nut.

[0012] Furthermore, in the present invention, the plurality of mounting holes are evenly distributed around the center of the flange blind plate.

[0013] Furthermore, in the present invention, a sealing ring is provided on the end face of the above-mentioned flange blind plate.

[0014] Furthermore, in the present invention, the above-mentioned flange blind plate is provided with a groove for accommodating the sealing ring.

[0015] Furthermore, in the present invention, the sealing ring is configured as a fluororubber O-ring.

[0016] Furthermore, in the present invention, the clamp includes a hoop sleeved on the pipe mouth, and connecting pieces are provided at both ends of the hoop, and the connecting pieces pass through bolts with adjustable tightness.

[0017] Furthermore, in the present invention, the bolts are provided with washers.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] 1. High processing efficiency: Traditional three-way valves use flanges and flange blind plates for connection, requiring several connection holes to be machined on the flanges, resulting in low production efficiency. The present invention replaces the flanges on the original three-way valves with detachable clamps, eliminating the need for drilling holes on the three-way valves. This eliminates the need for flange drilling during production, resulting in high processing efficiency and production efficiency.

[0020] 2. Low maintenance cost: Since traditional three-way valves use flanges and flange blind plates for connection, the flanges are the parts that bear the force and are easily damaged. In the utility model, a clamp is used to replace the flange and flange blind plate connection on the original three-way valve. If the clamp is damaged, it can be directly removed and replaced without replacing the entire three-way valve, which is convenient for maintenance and has low maintenance costs.

[0029] Example

[0030] This embodiment provides a hydraulic tool for a three-way valve, such as Figures 1-4 As shown, the specific structure is described as follows.

[0031] Combine Figure 1 As shown, the hydraulic tooling for the three-way valve of this embodiment includes a valve body 1, and three pipe openings 101 are provided on the left side, right side and bottom of the valve body 1. The liquid inside the valve body 1 can flow out through the pipe openings 101, or the liquid outside the valve body 1 can flow in through the pipe openings 101.

[0032] Further, Figure 1 A clamp 2 is installed on the left pipe opening 101 and the right pipe opening 101, respectively, and six fixing members 4 are installed on each clamp 2. Figure 1 、 Figure 3 and Figure 4 As shown, the hoop 2 mainly includes three parts: a hoop 201, a connecting piece 202 and a bolt 203. The hoop 201 is a broken iron ring, and the two connecting pieces 202 are respectively fixed at the broken positions of the hoop 201. The connecting piece 202 is provided with a hole for the bolt 203 to pass through.

[0033] When the clamp 2 is put on the pipe mouth 101, the nut on the bolt 203 is screwed to move the two connecting pieces 202 closer to each other, thereby tightening the hoop 201, and the clamp 2 tightens the pipe mouth 101, so that the pipe mouth 101 and the clamp 2 are fixedly connected.

[0034] It should be noted that, combined with Figure 3 and Figure 4 As shown, a washer 204 is installed on the bolt 203, so that the washer 204 replaces the connecting piece 202 and contacts the nut, thereby playing a role in anti-vibration and preventing loosening.

[0035] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, the blind flange plate 3 is in the shape of a "disc", and six mounting holes 301 are opened on the end surface of the blind flange plate 3. The six mounting holes 301 are evenly distributed around the center of the blind flange plate 3 to ensure uniform force after connection and fixation.

[0036] Further, combined Figure 1 and Figure 2 As shown, two annular grooves 302 are provided on the end face of the blind flange 3, and two sealing rings 6 are embedded in the grooves 302. When the blind flange 3 is fixed, the sealing rings 6 are squeezed by the end face of the blind flange 3 and the end face of the pipe mouth 101, playing a sealing role and ensuring the smooth progress of the test.

[0037] It should be noted that the sealing ring 6 can be a fluororubber O-ring 6 , which has a good sealing effect and a wide range of applications.

[0038] In some implementations of this embodiment, Figure 1 As shown, the end of the pipe mouth 101 is provided with an outer edge 102 that blocks the clamp 2 to prevent the clamp 2 from falling off, thereby improving the use effect. The fixing member 4 includes two parts: a screw 401 and a nut 402. The six screws 401 are fixedly connected to the hoop 201 of the clamp 2, and the six screws 401 are equally spaced on the hoop 201.

[0039] Further, combined Figure 1 As shown, after the clamp 2 and the pipe mouth 101 are fixedly connected, the mounting hole 301 of the blind flange plate 3 is aligned with the screw 401, the screw 401 is passed through the mounting hole 301, and then the nut 402 is screwed on from the outside of the blind flange plate 3. The nut 402 and the screw 401 are threadedly connected, and then the blind flange plate 3 is fixed to the end of the pipe mouth 101. The blind flange plate 3 seals the end of the pipe mouth 101.

[0040] Combine Figure 1As shown, the pipe openings 101 on the left and right sides are sealed with flange blind plates 3, and the bottom pipe opening 101 adjacent to the pipe openings 101 on the left and right sides is sealed with a plug 5. The plug 5 is an insert-type sealing method to avoid interference with the adjacent flange blind plates 3 during sealing.

[0041] The working principle of the hydraulic tooling for the three-way valve of the utility model is as follows:

[0042] Before conducting a water pressure test, the clamp 2 is fixedly connected to the pipe opening 101 of the valve body 1. When fixing, tighten the bolts 203 to bring the two connecting pieces 202 closer to each other, tighten the hoop 201, and let the clamp 2 tighten the pipe opening 101. Then, the flange blind plate 3 and the clamp 2 are fixedly connected through the fixing member 4. When fixing, the screw 401 passes through the mounting hole 301, and then the nut 402 is screwed on from the outside of the flange blind plate 3. The nut 402 and the screw 401 are threaded together, and then the flange blind plate 3 is fixed to the end of the pipe opening 101. After the flange blind plate 3 is fixed, it cooperates with the sealing ring 6 to seal the port of the pipe opening 101 to prevent liquid from leaking out. The detachable clamp 2 replaces the flange on the original three-way valve, so there is no need to drill holes on the three-way valve, which greatly reduces the processing time of the three-way valve and improves the processing efficiency and production efficiency of the three-way valve. The clamp 2 is used to replace the flange and flange blind plate 3 on the original three-way valve. If the clamp 2 is damaged, it can be directly removed and replaced without replacing the entire three-way valve. The maintenance is convenient and the maintenance cost is low.

[0043] In summary, the present invention provides a hydraulic tooling for a three-way valve, comprising a valve body 1, the valve body 1 being provided with a pipe opening 101, the pipe opening 101 being fitted with a detachably connected clamp 2, the end of the pipe opening 101 being provided with a blind flange plate 3, and the blind flange plate 3 being provided with a fixing member 4 fixedly connected to the clamp 2.
