Description

Technical Field

[0002] Pressure test is one of the common methods to judge whether the water pipe connection is reliable. During the pressure test, the joints, female joints and plugs must be checked one by one to ensure that there is no water leakage, otherwise it will directly affect the needle of the pressure tester. The pressure test is also a relatively simple method for inspecting water pipes.

[0003] However, when the existing test tool for pressurizing small pipelines is used to pressurize the water pipes, the air pressure is used to pressurize the water pipes through the pressure gauge. If this operation is performed for a long time, it is easy to damage the pressure gauge. At the same time, when the water pipes are pressurized, the pressure gauge will also shake. The long-term vibration of the pressure gauge can easily affect the accuracy of the pressure gauge. Therefore, we propose a test tool for pressurizing small pipelines. Utility Model Content

[0005] Therefore, the purpose of the present invention is to provide a test tool for pressurizing small pipelines, which solves the problem that when the existing test tool for pressurizing small pipelines pressurizes the water pipe, the air pressure pressurizes the water pipe through the pressure gauge. If this operation is performed for a long time, it is easy to cause damage to the pressure gauge. At the same time, when the water pipe is pressurized, the pressure gauge will also shake, and the pressure gauge will vibrate for a long time, which is easy to affect the accuracy of the pressure gauge.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A test tool for pressurizing small pipelines comprises a box body, an electric pressure pump and a pressure tank, wherein the electric pressure pump is fixedly installed on one side of the box body, a support plate is provided inside the box body for sliding up and down, a pressure tank is fixedly installed on one side of the top of the support plate, a telescopic tube is fixedly connected between one end of the pressure tank and one end of the electric pressure pump, a first one-way valve is fixedly installed on the telescopic tube, the other end of the pressure tank is fixedly connected to a delivery pipeline, and a pressure gauge is provided on the delivery pipeline.

[0008] Preferably, telescopic rods are fixedly installed on both sides of the interior of the box, and the movable ends of the two telescopic rods are fixedly connected to the two sides of the bottom surface of the support plate respectively, and the size of the support plate and the interior of the box are consistent.

[0009] Preferably, a support rod is fixedly installed at the bottom of the pressure gauge, a support tube is sleeved on the bottom of the support rod, the support tube is fixedly installed on the surface of the support plate, and a damping spring is fixedly installed between the inner bottom of the support tube and the bottom of the support rod.

[0010] Preferably, a second one-way valve is provided on the delivery pipeline between the pressure gauge and the pressure tank.

[0011] Preferably, there is a gap between one end of the delivery pipe and one side of the interior of the box, and a connecting pipe is fixedly installed on the other end of the delivery pipe.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:
