Embodiment Construction
[0012] see figure 1 , figure 2 , the present invention check valve performance testing device, including the air pump 1, 5-position manual valve 2, check valve 3, three-way joint 4, flow meter 5 and check valve fixture 6. The one-way valve 3 is placed on the one-way valve fixture. The outlet of the air pump, the air inlet and outlet of the one-way valve, and the two interfaces of the three-way joint are respectively connected with the two-position five-way manual valve to form a test circuit. The connection between the flowmeter and the three-way joint connected to another interface.
[0013] The two-position five-way manual valve in the present invention forms two connection positions with the air pump, one-way valve and three-way joint through manual conversion. The air inlet on one side of each connection position is connected to the air pump, and the air outlet and blind port on one side are respectively It is connected to the two ports of the three-way joint and connec...

The invention discloses a one-way valve property testing device which comprises an air pump, two five-way manual valves, a one-way valve, a T-joint, a flowmeter and a one-way valve clamp, wherein the one-way valve is placed on the one-way valve clamp; the outlet of the air pump, the air inlet and the air outlet of the one-way valve, and two connectors of the T-joint are respectively connected with the two five-way manual valves so as to form a testing loop; the flowmeter is connected with the another connector of the T-joint. As the air pump, the one-way valve and the flowmeter are connected through the two five-way manual valves and the T-joint, the one-way continuity of the one-way valve can be tested by manually reversing the two five-way manual valves, the one-way valve does not need to be mounted and clamped twice, and the testing efficiency and the precision of the one-way valve property testing device are improved. The one-way valve property testing device has the characteristics of being simple and economic in structure, convenient to operate and accurate in testing result.
Description
technical field [0001] The invention relates to a test device, in particular to a performance test device for a one-way valve. Background technique [0002] A check valve is a directional control valve in which airflow can only flow in one direction and cannot flow in the opposite direction. Its working principle is the same as that of a hydraulic check valve. The check valve is used in occasions where the air flow is not allowed to flow in reverse. For example, when the air compressor inflates the air tank, a check valve is installed between the air compressor and the air tank. When the air compressor stops working, it can prevent the air tank from The compressed air is returned to the air compressor. One-way valves are often combined with throttle valves and sequence valves to form one-way throttle valves and one-way sequence valves. [0003] The existing one-way valve testing system needs to clamp the tested one-way valve twice, the efficiency of the testing system is ...
