Embodiment 1

[0027] Such as figure 1 As shown, a rubber hose online high-pressure constant pressure testing system includes a control terminal, a pressure test container 1 made of rubber hose with an opening at one end, a high-pressure pump 2 and a conduit 3. The inlet of the conduit 3 is connected to the high-pressure pump 2 Outlet, the outlet of the conduit 3 communicates with the opening of the pressure test vessel 1; the conduit 3 from the high pressure pump 2 to the pressure test vessel 1 is sequentially provided with a one-way valve 4 and a pneumatic shut-off valve 5; the high pressure pump 2 and the one-way A pump end unloading valve 6 is arranged on the conduit 3 between the valves 4; a container unloading valve 7 is arranged on the conduit 3 between the one-way valve 4 and the pneumatic stop valve 5; the pneumatic stop valve 5 and the test The conduit 3 between the pressure vessels 1 is provided with pressure detection equipment; the high-pressure pump 2, pneumatic stop valve 5, p...

Embodiment 2

[0033] This embodiment is a further improvement made on the basis of Embodiment 1. The difference between this embodiment and Embodiment 1 is:

[0034] The high-pressure pump 2 described in this embodiment is a high-pressure water pump installed in the water source, and the high-pressure water pump is used to inject water into the conduit 3 for high-pressure constant pressure testing, especially suitable for the pressure test container 1 with a large volume, and can be filled with tap water Fill water into the pressure test vessel 1. When filling water, pay attention to exhaust the air as much as possible. You can set an exhaust port on the pressure test vessel 1. The exhaust port is generally set above the vessel. It is required that the low-pressure water inlet hole and the high-pressure water inlet hole should be separated. After the water injection is completed, manually close the gate valve of the low-pressure water inlet hole, and then use the rubber hose online high-pres...

Embodiment 3

[0041] This embodiment is a further improvement made on the basis of embodiment 1 or embodiment 2. The difference between this embodiment and embodiment 1 or embodiment 2 is:

[0042] Preferably, a high-pressure filter 9 is provided on the conduit 3 between the pressure detection device and the pneumatic shut-off valve 5 . The high-pressure filter 9 is suitable for filtering solid and liquid impurities in high-pressure compressed air, ensuring that only particles with a particle size smaller than the required size can enter, and providing system accuracy.

[0043] Preferably, a pressure gauge 10 is provided on the conduit 3 between the pneumatic shut-off valve 5 and the pressure test vessel 1, which is convenient for observing the pressure on site, and is cheap and practical.

[0044] Preferably, the outlet end of the conduit 3 is provided with a manual unloading valve 11 . The manual unloading valve 11 can be used after the pressure maintaining is completed, and the pressure...

Abstract

The invention belongs to the technical field of rubber pipe pressure testing, and discloses a rubber pipe online high-pressure and constant-pressure testing system which comprises a control terminal,a pressure test container, a high-pressure pump and a guide pipe. An inlet of the guide pipe is communicated with an outlet of the high-pressure pump, an outlet of the guide pipe is communicated withan opening of the pressure test container, a one-way valve and a pneumatic stop valve are sequentially arranged on the guide pipe, a pump end loading valve is arranged between the high-pressure pump and the one-way valve, a container loading valve is arranged between the one-way valve and the pneumatic stop valve, a pressure detection device is arranged between the pneumatic stop valve and the pressure test container, the high-pressure pump, the pneumatic stop valve, the pump end loading valve, and the container loading valve and the pressure detection device are electrically connected with the control terminal. According to the system, a lot of preparation time of manual testing is saved, the system is high in automation degree, the working efficiency is improved, product quality is stable, and the quality and the high-pressure and constant-pressure testing efficiency of a rubber pipe are improved in the production process of the rubber pipe.

Description

technical field [0001] The invention belongs to the technical field of rubber hose pressure testing, and in particular relates to an online high-pressure constant pressure testing system for rubber hoses. Background technique [0002] Rubber and rubber products have been widely used in the industrial field, and people's lives are closely related to rubber products. Ensuring the quality of rubber products is related to the survival of rubber companies. The process of constant pressure inspection of finished rubber hoses has become one of the key processes in our rubber hose process. one. [0003] The rubber hose is generally composed of an inner rubber layer, a skeleton layer and an outer rubber layer. The high-pressure constant pressure test plays a very important role in the performance inspection of the high-pressure resistance of the rubber hose. The high-pressure constant pressure equipment used is to determine the quality of the pressure resistance of the rubber hose an...
