Problems solved by technology

[0003] Existing hydraulic, pneumatic or oil pressure testing machines for valves only have a single top-pressure test bench, which can test limited specifications of valves, and when the top pressure of the test bench is insufficient, the valve is likely to slip and cause sealing Not tight, the test is inaccurate
In addition, the existing pressure testing machine only has a single test bench, and the comprehensive utilization rate of machine parts is low

Embodiment 1

[0030] Refer to attached figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 . A pressure testing machine for testing the pressure performance of valves, including a control console 1, a top-pressure test bench 2, a gripper-type test bench 3, and a supply medium that cooperates with the top-pressure test bench 2 and the gripper-type test bench 3 respectively Pressure device and oil pressure driving device 5, the supply medium pressure device is a water supply pressure device 4, and the water supply pressure device 4 and oil pressure driving device 5 are all controlled by the console 1. The jaw-type test bench 3 includes a jaw test bench 30, an active gripper 31 installed on the gripper test bench 30, and two driven grippers (not shown in the figure) that act synchronously with the active gripper 31 , a push-pull oil cylinder 32 located inside the jaw test bench 30 and used to push the active jaw 31 to move horizontally, and three clamping oil cylinders 33 respectiv...

Embodiment 2

[0037] Refer to attached figure 1 And attached Figure 9 . The implementation of this embodiment is basically the same as that of Embodiment 1, the difference is that the medium supply pressure device is an oil supply pressure device 4', which includes an oil pump 40' and a sealed oil storage tank 41 communicated with the oil pump 40' ', the sealed oil storage tank 41' is provided with two-way oil outlet pipes 410', 411', and the two-way oil outlet pipes 410', 411' correspond to the top pressure test bench 2 and the jaw type test bench 3 respectively. The medium outlet ports are connected, and each oil outlet pipe is equipped with a pressure reducing valve 42' for adjusting the oil pressure.

[0038]This testing machine is suitable for testing valves used on oil pipelines. It supplies constant oil pressure to the inside of the valve through the oil pressure device 4' to detect its oil pressure resistance, and observes the oil pressure gauge on the console 1 to display its in...

Abstract

The invention discloses a pressure tester for detecting compression performance of a valve. The pressure tester comprises an operating table, a top pressure type test table, a clamping jaw type test table, a medium pressure supply device and an oil pressure driving device, wherein the medium pressure supply device and the oil pressure driving device are matched with the top pressure type test table and the clamping jaw type test table respectively; both the medium pressure supply device and the oil pressure driving device are controlled by the operating table; the clamping jaw test table comprises a clamping jaw test table, a driving clamping jaw, two driven clamping jaws, a push-pull oil cylinder and three clamping oil cylinders; the driving clamping jaw is arranged on the clamping jaw test table; the two driven clamping jaws synchronously act with the driving clamping jaw; the push-pull oil cylinder is positioned in the clamping jaw test table and is used for pushing the driving clamping jaw to horizontally move; the clamping oil cylinders are used for driving the corresponding driving and driven clamping jaws to perform clamping action on the valve; and the push-pull oil cylinder and the three clamping oil cylinders are connected with the oil pressure driving device respectively. The pressure tester comprises the top pressure test table and the clamping jaw test table. Two valves can be simultaneously tested, the testing efficiency can be improved, the comprehensive utilization rate of equipment is high, and the cost is saved.

Description

technical field [0001] The invention relates to a testing device, in particular to a pressure testing machine for testing the pressure performance of valves, which can extensively test valves used in water pipelines, gas pipelines and oil pipelines. Background technique [0002] In view of the valve as an opening and closing device, there are very strict requirements on its sealing performance, so the sealing performance test must be done during the production process and before leaving the factory, and the valve must be subjected to a two-way pressure test, that is, closing the valve to the cavity on both sides of the valve The pressure-resistant seal test is carried out within the specified time and with the specified pressure. [0003] Existing hydraulic, pneumatic or oil pressure testing machines for valves only have a single top-pressure test bench, which can test limited specifications of valves, and when the top pressure of the test bench is insufficient, the valve is...
