Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve detection, in particular to a multi-station valve pressure detection device. Background Art
[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveyed medium. They are control components in fluid conveying systems and have functions such as cutting off, regulating, diverting, preventing backflow, stabilizing pressure, diverting or overflow pressure relief. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
[0003] After valve assembly, a series of functional and performance tests are required, including pressure testing, sealing testing, and leak testing. Traditional pressure testing is usually carried out using a pre-connected pressure flange + pressure pump, but this method is usually only suitable for pressure testing a single valve and is relatively inefficient.
[0004] To this end, the present application designs a multi-station valve pressure detection device to solve the above problems. Summary of the Invention
[0005] In order to make up for the deficiencies in the prior art, the utility model provides a multi-station valve pressure detection device.
[0006] A multi-station valve pressure detection device includes a tank body, a pressure pump interface, a station ball valve, a flange, a pressure gauge, a water tank, an exhaust ball valve, a return pipe, a pressure relief ball valve, and casters. It is characterized by:
[0007] The casters are mounted on the bottom of the tank body to facilitate the movement of the device.
[0008] The tank body is a large-diameter seamless steel pipe with both ends welded and sealed. The pressure pump interface is located at one end of the tank body; the other end is equipped with an exhaust ball valve and a water tank.
[0009] The top of the tank body is provided with a plurality of valve mounting flanges, which are connected to the tank body through the station ball valves. When the number of valves to be pressure tested is less than the number of pressure stations, the ball valves of the idle stations can be closed.
[0010] The pressure gauge is installed on the tank body and can monitor the internal pressure of the tank body in real time.
[0011] The pressure relief ball valve is installed at the opposite end of the pressure pump interface. After the pressure testing work is completed, the pressure relief ball valve is opened to release the internal pressure, which facilitates the disassembly of the valve.
[0012] Furthermore, the return pipe is connected to the tank body through a pressure relief ball valve, and when the pressure is relieved, the water inside the tank body flows out through the return pipe.
[0013] Furthermore, the water outlet end of the return pipe is located above the water adding tank, and the pressure-relieved return water flows back to the water adding tank, thereby realizing the reuse of the pressurized water.
[0014] The beneficial effects of the utility model are:
[0015] Compared with the traditional single-station valve pressure detection device, the utility model is safer and more efficient, realizes the recycling of pressure water, and improves the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.
[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0022] Figure 1-Figure 2 This is a specific embodiment of the present invention, which is a multi-station valve pressure detection device. The specific usage is as follows:
[0023] First, close the water inlet ball valve 11 and the drain ball valve 9 of the equipment, open the work position ball valve 3 and the exhaust ball valve 6, and inject clean water for pressurization into the tank body 1 through the water adding tank 7 of the equipment in advance. Since the liquid level of the water adding tank 7 is higher than the flange 4, as the water overflows through the flange 4, the tank body 1 is filled with clean water by default.
[0024] Connect the valves requiring pressure testing to flange 4 via high-pressure gaskets and tighten the connecting bolts. If the number of valves requiring pressure testing is less than the number of pressure testing stations, close the pressure testing ball valves 3 in the unused stations. After connecting the pressure testing pump interface 2 to the pressure testing pump, start the pressure testing pump. As the pressure rises, exhaust ball valve 6 will be used to expel air from the equipment. Close the exhaust ball valve 6. Continue to increase the pressure inside the tank 1 to the required test pressure, and then check the valves for pressure resistance and leakage.
[0025] After the test is completed, the pressure pump is removed and the water inlet ball valve 11 is closed. The drain ball valve 9 is opened to release the pressure of the tank body 1. The excess water will be discharged to the water tank 7 through the return pipe 8 for use in the next pressure test. After the pressure of the tank body 1 is released, the valve on the pressure station flange 4 can be removed, and a round of pressure testing is completed.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
