Abstract

The utility model relates to a new pressure test apparatus, comprising a pressure pump, a tank, and a pressure gauge, and is characterized in that the pressure pump, whose output terminal is connected with a pressure relief valve, a pressure-increasing valve and a non-return valve in parallel. The other terminal of the non-return valve is connected with the container to be tested. And the connecting pipe between the container and the non-return valve is linked in parallel with a pressure gauge and an unloading valve, the other terminal of which is in connection with input terminal of the pressure-increasing valve. And then the tank is connected with the output terminals of the pressure relief valve and the pressure-increasing valve. The utility model is characterized in that the model can be provided with the double effect of the pressure-increasing and the pressure-decreasing at the same time and be easy to perform the pressure-increasing test to tank container.

Description

Novel pressure testing device

Technical field

The utility model relates to a kind of pressure testing device, particularly a kind of novel pressure testing device.

Background technology

At present when production and processing has the water containers such as water tank of certain pressure, need carry out the pressure test of water-filling, the general retaining valve of a valve control that adopts of traditional test pump carries out water-filling to underproof container, after reaching certain pressure, stop water-filling, observe container whether seepage is arranged then, whether withstand voltage to detect this container, but when needing to reduce pressure in test, then existing test pump can't be finished the stress-relief process that reduces pressure because of its structure, therefore bring the inconvenience of using to withstand voltage test, carried out a pressure test equally and more operation.

Summary of the invention

The purpose of this utility model is that test pump is carrying out existing the problems referred to above in the water-filling pressure testing in the solution prior art to pressure vessel, and a kind of novel pressure testing device with pressurization, decompression double effects is provided.The utility model designs novel pressure testing device, comprise forcing pump, water tank, tensimeter, it is characterized in that: forcing pump water receiving case, the pressure delivery side of pump also is connected to surplus valve, pressure charging valve and retaining valve, the tested container of testing of another termination of retaining valve, on by the connecting pipe between test container and the retaining valve and be connected to tensimeter and unloading valve, the other end of unloading valve is attempted by the input end of pressure charging valve, and the output terminal of surplus valve and pressure charging valve inserts water tank.The utility model has the advantages that can realize having pressurization simultaneously, the decompression double effects, convenient applied voltage test of water tank container being carried out pressure.

Description of drawings

Below in conjunction with drawings and Examples the utility model is elaborated,

Accompanying drawing is a structural representation of the present utility model,

Embodiment

Output terminal 3 and be connected to surplus valve 4, pressure charging valve 5 and retaining valve 6, the tested container 7 of testing of another termination of retaining valve 6, on by the connecting pipe 8 between test container 7 and the retaining valve 6 and be connected to tensimeter 10 and unloading valve 9, the other end of unloading valve 9 is attempted by the input end of pressure charging valve 5, and the output terminal of surplus valve 4 and pressure charging valve 5 inserts water tank 2.Open unloading valve 9 when using pressure testing earlier, slowly regulate pressure charging valve 5 then, if will transfer big pressure, then regulate clockwise, improve intrasystem pressure by reducing the backwater amount, if will turn pressure down, then regulate counterclockwise, reduce intrasystem pressure by increasing the backwater amount, when system pressure exceeds authorised pressure, surplus valve 4 can automatic backwater unloading, can prevent from that system pressure is too high to meet accident.If need keep-up pressure; then can close unloading valve 9 earlier; pump is shut down then; pressure when system keeps closing is after pressure testing is finished, if need shed pressure; as long as then open unloading valve 9; be discharged into water tank from unloading valve 9 through pressure charging valves 5 by the pressure in test container 7 and the pipeline, the utility model has changed that traditional test pump can only boost continuously and use shortcoming that can't step-down in the pressure testing process, and operation is very convenient in test.

Claims

1, novel pressure testing device, comprise forcing pump, water tank, tensimeter, it is characterized in that: forcing pump water receiving case, the pressure delivery side of pump also is connected to surplus valve, pressure charging valve and retaining valve, the tested container of testing of another termination of retaining valve, on by the connecting pipe between test container and the retaining valve and be connected to tensimeter and unloading valve, the other end of unloading valve is attempted by the input end of pressure charging valve, and the output terminal of surplus valve and pressure charging valve inserts water tank.
