Technical Field

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

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

[0003] During the construction of industrial installation projects, for the construction of process pipelines, according to the requirements of the design and relevant specifications, it is necessary to conduct pressure testing and random inspections on the incoming process valves. In the conventional system pressure testing process, the system pressure test is mostly carried out on individual systems one by one. This method can only detect a single valve system at a time, which belongs to the "one-test-at-a-time" pressure testing device. For the detection of multiple valves of different numbers, it is necessary to repeat this test, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0013] A portion of the rotating rod passes through the partition plate and is arranged close to the valve connecting section to form a second installation section, on which a blade is fixedly mounted. The blade is rotated to drive the limiting plate to rotate and block the water inlet.

[0014] Furthermore, the valve connecting section is formed with a branch pressure relief port corresponding to the installation position of the blade, and a cover plate is detachably installed on the branch pressure relief port. Water flows through the water inlet and flows out of the branch pressure relief port to drive the blade to rotate, so that the limit plate rotates and blocks the water inlet.

[0028] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] See also Figure 1 and Figure 2 A cluster water valve pressure testing device comprises: a pressure testing body 1, a water storage space is formed in the pressure testing body 1, a water inlet pipe 3 is formed on the top of the pressure testing body 1, and the water inlet pipe 3 is connected to the water storage space; a plurality of valve connecting pipes 2 are formed on the side of the pressure testing body 1 and are connected to the water storage space, the valve connecting pipe 2 forms a valve connecting section on the side away from the pressure testing body 1, and a water pipe switch is arranged in the valve connecting pipe 2; and a pressure gauge 4 is arranged at the end of the pressure testing body 1, and the pressure gauge 4 measures the pressure in the water storage space.

[0030] In the present utility model, a preferred implementation is: the pressure test body 1 is barrel-shaped, and a support frame is fixedly installed at the bottom of the pressure test body 1. Before the pressure test body 1 is filled with water, the valve to be tested is fixedly installed on the valve connecting section of the pressure test body 1 to determine whether the valve to be tested is firmly installed. After confirmation, water is poured into the pressure test body 1 through the water inlet pipe 3, and the pressure gauge 4 is used to confirm whether the pressure in the pressure test body 1 meets the test requirements. When the water pressure in the pressure test body 1 reaches the test requirements, water filling is stopped, and the test is continued until the test duration meets the test requirements.

[0031] See also Figure 3Furthermore, the water pipe switch includes: a partition plate 8 disposed in the valve connecting pipe 2 and blocking the valve connecting pipe 2, the partition plate 8 being formed with a water inlet; a position-adjustable limit plate disposed on the side of the partition plate 8, the limit plate being attached to the side of the partition plate 8, and the position of the limit plate being adjusted to block the water inlet. When the number of the valve connecting sections is greater than the valves to be tested, the limit plates in the excess number of valve connecting sections can be adjusted so that the limit plates block the water inlet, thereby preventing the water in the pressure test body 1 from being discharged from the water inlet, thereby affecting the test effect of the pressure test body 1.

[0032] See also Figure 4 Further, the partition plate 8 is rotatably provided with a rotating rod, a portion of the rotating rod passes through the partition plate 8 and is arranged away from the valve connection section to form a first installation section, and the limit plate is fixedly installed on the first installation section; a portion of the rotating rod passes through the partition plate 8 and is arranged close to the valve connection section to form a second installation section, and a blade 7 is fixedly installed on the second installation section, and the blade 7 is rotated to drive the limit plate to rotate and block the water inlet. Preferably, the limit plate can be rotated by adjusting the blade 7, so as to conveniently block the water inlet with the limit plate.

[0033] Furthermore, the valve connection section is formed with a branch pressure relief port 6 corresponding to the installation position of the blade 7, and a cover plate 61 is detachably installed on the branch pressure relief port 6. Water flows through the water inlet and flows out of the branch pressure relief port 6 to drive the blade 7 to rotate, so that the limit plate rotates and blocks the water inlet. Preferably, when the valve connection section is not installed with a valve, the valve connection section can be easily closed by opening the cover plate 61 of the branch pressure relief port 6.

[0034] Furthermore, a pressure relief valve 62 is provided in the branch pressure relief port 6. The branch pressure relief port 6 is closed by the pressure relief valve 62.

[0035] Furthermore, a limiting block 71 is fixedly installed on one side of the blade 7 away from the rotating shaft, and a clamping block 72 is formed on the inner wall of the valve connecting section corresponding to the limiting block 71. When the limiting plate blocks the water inlet, the clamping block 72 abuts against the limiting block 71. The clamping block 72 and the limiting block 71 can prevent the blade 7 from continuing to rotate, causing the limiting plate to move, so that the water inlet is reopened.

[0036] Furthermore, the water inlets are provided in plurality, and the limiting plates are provided in plurality corresponding to the number of the water inlets.

[0037] Furthermore, a water inlet butterfly valve is installed on the water inlet pipe 3.

[0038] Furthermore, a water outlet pipe 5 communicating with the water storage space is fixedly installed at the bottom of the pressure test body 1 , and a water outlet butterfly valve is installed on the water outlet pipe 5 .

[0039] Furthermore, the diameter of the valve connection section is determined according to the size of the valve to be tested. By setting the valve connection section to different sizes, the pressure test body 1 can test different valves to be tested at the same time.

[0040] The following is an explanation of the use of a cluster type water valve pressure testing device of the utility model.

[0041] The pressure test body 1 is barrel-shaped, and a support frame is fixedly installed at the bottom of the pressure test body 1. Before filling the pressure test body 1 with water, the valve to be tested is fixedly installed on the valve connecting section of the pressure test body 1 to determine whether the valve to be tested is installed firmly enough. After confirmation, water is poured into the pressure test body 1 through the water inlet pipe 3, and the pressure gauge 4 is used to confirm whether the pressure in the pressure test body 1 meets the test requirements. When the water pressure in the pressure test body 1 meets the test requirements, water filling is stopped, and the test is continued until the test duration meets the test requirements; when the number of the valve connecting sections exceeds the valve to be tested, the pressure relief valve 62 can be opened. When water is poured into the pressure test body 1, water flows through the water inlet and drives the blade 7 to rotate. The blade 7 drives the limit plate to rotate through the rotating shaft, so that the limit plate closes the water inlet to ensure that the water pressure in the pressure test body 1 will not leak.

A person skilled in the art can make various variations of the utility model according to the above description.
