Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to a valve body water pressure testing device. Background Art

[0002] The valve body is a control component in the fluid conveying system, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. The valve body needs to be tested after manufacturing or maintenance to test its pressure resistance and sealing performance.

[0003] The existing water pressure testing equipment has an unfixed position when the valve body is placed, and the sealing effect is poor due to the eccentricity of the valve body during placement, which requires repeated debugging and reduces the test effect.

[0004] Therefore, in order to solve the above problems, it is necessary to design a valve body water pressure testing device. Utility Model Content

[0005] The utility model aims to provide a valve body water pressure testing device to solve the technical problem of poor sealing effect of the existing water pressure testing device.

[0006] In order to solve the above technical problems, the utility model provides a valve body water pressure testing device, comprising:

[0007] A test bench, the top of which is provided with a positioning plug and a positioning support;

[0008] A support platform is arranged on the top of the test bench, and a cylinder is arranged on the top of the support platform;

[0009] The telescopic end of the cylinder is connected to a sealing plug;

[0010] The cylinder is suitable for driving the sealing plug to move up and down; and

[0011] The positioning plug and the positioning support are suitable for positioning the valve body, so that when the sealing plug moves downward, the positioning plug cooperates with the valve body to seal.

[0012] Furthermore, a water valve is provided on the side of the support platform;

[0013] The bottom of the water valve is connected with a bamboo tube.

[0014] Furthermore, a through hole is provided in the middle of the positioning plug;

[0015] A first pipe is provided at the bottom of the positioning plug;

[0016] The first pipe is connected to the through hole; and

[0017] The bottom of the first pipeline is connected to a pressure relief valve.

[0018] Furthermore, a water tank is provided below the pressure relief valve.

[0019] Furthermore, a second pipeline is connected to the side of the first pipeline; wherein

[0020] The other end of the second pipeline is connected with a check valve.

[0021] Furthermore, a pressure pump is connected to the other end of the check valve.

[0022] Furthermore, a pressure gauge is connected to the second pipeline.

[0023] The beneficial effects of the present utility model are as follows:

[0024] (1) By sleeving the valve body on the positioning plug, and then placing the control end on the positioning support member, the valve body can be stably placed. Then, by starting the cylinder, the cylinder drives the sealing plug to move downward to seal the top of the valve body and apply pressure to the valve body, so that the positioning plug at the bottom fully seals the bottom of the valve body. Through the above steps, rapid positioning and support can be achieved, and the situation that the valve body tilts and causes poor sealing can be prevented.

[0025] (2) By sleeving the valve body on the positioning plug, placing the control end on the positioning support member, opening the water valve to make water flow into the valve body from the bamboo joint pipe, then driving the sealing plug to move downward by the cylinder to seal the top of the valve body. At this time, start the pressure pump to pressurize the inside of the valve body, and then detect the pressure change through the pressure gauge. After the test is completed, open the pressure relief valve to relieve the pressure, and the water tank collects the water discharged by the pressure relief valve. Through the above steps, rapid testing and pressure relief can be achieved.
