[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: a valve test bench, including an equipment main body 100 and an auxiliary platform 200 erected in the tooling area of ​​the equipment main body 100 for supporting the valve to be tested, the auxiliary platform 200 includes a fixed seat 210 and a cylinder 220 distributed and fixedly installed on the top of the fixed seat 210 along the vertical direction, the output end of the cylinder 220 is fixedly connected with a movable plate 230 distributed along the horizontal plane, and the top of the movable plate 230 is equipped with two V-shaped frames 240 for placing the valve to be tested, the V-shaped frame 240 includes a mounting frame 2410 and two roller groups 2430 fixedly installed on the top of the mounting frame 2410 through supports 2420, and the two roller groups 2430 are distributed along the inclined direction and are symmetrically distributed.

[0029] Based on the above-mentioned structural setting, the valve test bench is composed of an equipment body 100 and an auxiliary platform 200, wherein the auxiliary platform 200 is set up in the tooling area of ​​the equipment body 100. Specifically, during the working process, the operator lifts the valve to be tested to the auxiliary platform 200 with the help of a lifting device, and the valve to be tested is placed on two V-shaped frames 240. At the same time, the two flange ends of the valve to be tested are respectively located on the outside of the two V-shaped frames 240. Subsequently, the operator controls the lifting and lowering of the output end of the cylinder 220 to adjust the height of the valve to be tested. The output end of the cylinder 220 is extended and retracted, which can drive the movable plate 230 to rise and fall, thereby driving the valve to be tested set up on the two V-shaped frames 240 to rise and fall. When the valve to be tested is adjusted to a suitable height, the operator can use the roller group 2430 to perform a translation operation on the valve to be tested until the flange end on one side of the valve to be tested is aligned and fits with the fixed clamping plate on the equipment body 100, and cooperates with the slidable clamping plate. Under the action of the two clamping plates, the positioning tooling of the valve to be tested can be realized. The valve test bench is provided with an auxiliary table 200 in the tooling area of ​​the equipment body 100, which can structurally support the valve to be tested that is hoisted to the tooling area to avoid shaking of the valve to be tested. At the same time, the cylinder 220 and the V-frame 240 can be used to respectively realize the lifting and lateral movement of the valve to be tested, which is convenient for the operator to perform positioning operations.

[0030] Furthermore, a positioning groove 2120 is provided at the center of the top surface of the fixing seat 210 for accommodating the bottom of the air cylinder 220, and the circumferential side walls of the fixing seat 210 are provided with slopes 2110 distributed along the inclined direction. The positioning groove 2120 facilitates the positioning and installation of the air cylinder 220, and the setting of the slope 2110 can divert the water flow leaking during the valve test.

[0031] Furthermore, it also includes a cover shell 260 that is disposed outside the cylinder 220 and fixedly connected to the fixing seat 210, and the top of the cover shell 260 is connected to the bottom surface of the movable plate 230 through a telescopic protective cover 2610. The cover shell 260 and the telescopic protective cover 2610 can form a closed and effective protection outside the cylinder 220 without affecting the telescopic action of the output end of the cylinder 220.

[0032] Furthermore, two guide posts 2130 are fixedly connected to the fixing seat 210 and are both distributed in the vertical direction. The two guide posts 2130 are respectively movable and penetrate the two sides of the movable plate 230. Two parallel connecting frames 2440 are vertically welded between the two mounting frames 2410. The movable plate 230 rises and falls with the extension and retraction of the output end of the cylinder 220. The setting of the two guide posts 2130 plays a guiding and limiting role in the lifting and lowering of the movable plate 230, thereby ensuring the smooth lifting and lowering of the valve to be tested. The two connecting frames 2440 are welded between the two mounting frames 2410, connecting the two V-shaped frames 240 and forming the two into an integral component, thereby ensuring the structural strength of the V-shaped frames 240.

[0033] Furthermore, it also includes four dampers 250 distributed in a rectangular array and erected in the vertical direction, and the four dampers 250 are divided into two groups and respectively assembled between the movable plate 230 and the two mounting frames 2410. Among them, the V-shaped frame 240 directly contacts the valve to be tested and provides structural support for the valve to be tested. The setting of the damper 250 can provide effective buffering when the valve is placed on the V-shaped frame 240, play a certain protective effect on the valve, and extend the service life of the V-shaped frame 240.
