Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figure 1 As shown, a valve testing fixture according to one embodiment of the present invention includes a base assembly 1, a support assembly 2 installed on a pair of inner walls of the base assembly 1, a clamping assembly 3 installed on a pair of opposite inner walls of the support assembly 2, a control assembly 4 matching the clamping assembly 3 installed on the opposite inner walls of the pair of clamping assemblies 3, and a limiting assembly 5 matching the base assembly 1 installed on the bottom outer wall of the clamping assembly 3. By rotating the control assembly 4, the pair of clamping assemblies 3 are driven to clamp the valve. By operating the limiting assembly 5, the support assembly 2, the clamping assembly 3 and the control assembly 4 are driven to rotate, thereby driving the valve into the water tank 101 in the base assembly 1, and then subsequent testing can be carried out.

[0030] like Figure 2 and Figure 7 As shown, the base assembly 1 includes a water tank 101. A pair of support plates 102 are integrally formed on the top end face of the water tank 101. Rotating grooves 1021 matching the support assembly 2 are formed on the opposite side walls of the pair of support plates 102. A first bearing is installed on the inner wall of each of the pair of rotating grooves 1021. The support assembly 2 includes a support tube 201. The outer walls of both ends of the support tube 201 are fixedly connected to the inner wall of the inner ring of the bearing. A pair of vents 2011 are formed on the bottom end face of the support tube 201. A connecting pipe 202 is installed on the bottom end face of the support tube 201 below the pair of vents 2011. The interior of the connecting pipe 202 communicates with the vents 2011. A first bearing is installed on the top end face of the support tube 201. The air inlet 2012 is connected to an air compressor at one end. During use, the air generated by the air compressor enters the support tube 201 through the air inlet 2012, and then enters the connecting tube 202 through the air vent 2011. After passing through the connecting tube 202, it is delivered to the clamping assembly 3, and then from one side of the clamping assembly 3 to the valve. If bubbles are generated in the water, it indicates that the valve has a sealing problem and there is a certain leakage. Otherwise, it is qualified.

[0031] like Figures 2-4As shown, the clamping assembly 3 includes a pair of fixed plates 301 and a pair of second clamping plates 303. Fixed posts 306 are fixedly connected to the inner walls of the opposite bottom ends of the fixed plates 301. The top end face of the fixed plates 301 is fixedly connected to the bottom end face of the supporting round tube 201. A vent hole 3011 matching the connecting tube 202 is opened on the side wall of the fixed plates 301. One side wall of the connecting tube 202 is fixedly connected to the side wall of the fixed plates 301 located at the vent hole 3011. The interior of the connecting tube 202 communicates with the vent hole 3011. A first clamping plate 302 is welded to one side wall of the fixed plates 301, and the second clamping plates 303 are located on the side wall of the first clamping plates 302. On one side, a first clamping plate 302 and a second clamping plate 303 are respectively located at both ends of the valve component for clamping and fixing it. Support plates 3032 for supporting the valve component and sealing strips 3031 for ensuring a test seal are fixedly connected to the opposite sidewalls of the first clamping plate 302 and the second clamping plate 303. A first auxiliary block 304 is integrally formed on the top end face of the second clamping plate 303. A threaded hole matching the control component 4 is opened on the outer wall of the first auxiliary block 304. A second auxiliary block 305 is integrally formed on the bottom end face of the second clamping plate 303. A sliding groove matching the fixing post 306 is opened on the bottom outer wall of the second auxiliary block 305. The second auxiliary block 305 slides on the outer wall of the fixing post 306 through the sliding groove. The control component 4 includes a bidirectional threaded rod 401. Second bearings are installed at both ends of the bidirectional threaded rod 401. A rotating handle 402 is installed on the outer wall of the bidirectional threaded rod 401. Each pair of fixing plates 301 has mounting holes on their opposing inner walls that match the bidirectional threaded rod 401. Bearings are fixedly connected to the inner walls of these mounting holes, and the outer walls of both ends of the bidirectional threaded rod 401 are fixedly connected to the inner walls of the bearing inner rings. Before testing, the two venting ends of the valve are aligned with one side of the sealing strip 3031 on the first clamping plate 302 and the second clamping plate 303, respectively, so that the bottom end face of the valve is placed above the support plate 3032. Then, the rotating handle 402 is turned to rotate the bidirectional threaded rod 401. Simultaneously, the rotation of the bidirectional threaded rod 401 causes a pair of first auxiliary blocks 304 to move in opposite directions, achieving stable clamping of the valve by the second clamping plate 303. During testing, gas transmitted from the support assembly 2 is delivered to the inside of the valve through the vent 3011, thus completing the valve testing.

[0032] like Figures 5-6As shown, a clearance groove 1011 matching the limiting component 5 is provided on one side wall of the water tank 101. The limiting component 5 includes a limiting rod 501, and several sets of limiting holes 5011 are provided on the side wall of the limiting rod 501. A locking pin 504 is engaged in the limiting hole 5011. The outer wall of the limiting rod 501 passes through and slides on the inner wall of the clearance groove 1011. A rotating hole is provided at one end of the limiting rod 501, and a hand pull ring 503 is rotatably connected in the rotating hole. A connecting ring 502 is fixedly connected to the other end of the limiting rod 501. The inner wall is attached to and rotated on the outer wall of the fixed column 306. After the test is completed, pull the hand ring 503 to drive the limit rod 501 through the relief groove 1011 to move outward, so that the other end of the limit rod 501, the connecting ring 502, pulls the fixed column 306 to move outward, thereby moving it to the top of the water tank 101, so that the locking pin 504 is engaged in the limit hole 5011 near the relief groove 1011, thereby fixing the limit rod 501. After rotating the handle 402 in the opposite direction, a pair of valves are taken out, and then the next set of valves is tested.

[0033] Before use, such as Figure 1 As shown, this is the initial state of the clamp. First, fill the base assembly 1 with water, connect the support assembly 2 to the air compressor, then place the two valves onto a pair of clamping assemblies 3, and operate the control assembly 4 to clamp and fix the valves in place. During use, as... Figure 2 As shown, the operating limit component 5 slowly moves the bottom end of the clamping component 3 into the water surface of the water tank 101, so that the valve is completely immersed in the water. The air compressor is turned on, and the air is driven through the support component 2 and the clamping component 3 into the valve, thus completing the valve test. This valve test fixture can test two valves simultaneously, and disassembly is convenient and quick, with high efficiency, greatly increasing work efficiency.
