Detailed Description
The following description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will provide a better understanding of the function and features of the utility model.
As shown in the figure, the automatic coaxial pipe cleaning and leakage detecting combined equipment comprises an operation table and a workbench, and is characterized in that the operation table comprises a connecting pipeline, one end of the connecting pipeline is connected with a water pump 1, the other end of the connecting pipeline is connected with the workbench, a water inlet valve 2 and a one-way valve 3 are sequentially arranged on the connecting pipeline from the water pump 1 to the workbench, a pipeline is further arranged between the one-way valve 3 and the workbench and is respectively connected to a low-pressure valve 4, a high-pressure valve 5 and an exhaust valve 6, the low-pressure valve 4 is respectively connected with low-pressure gas, the high-pressure valve 5 is connected with high-pressure gas, and the exhaust valve 6 is connected with atmosphere; the testing device is characterized in that an operation table gas-liquid inflow pipeline and a gas-liquid outflow pipeline are arranged on the workbench, a plurality of testing pipelines are arranged between the operation table gas-liquid inflow pipeline and the operation table gas-liquid outflow pipeline, a coaxial pipe mounting position 9 is arranged on each testing pipeline and used for mounting a coaxial pipe, a manual valve 10 is arranged between the coaxial pipe mounting position and the operation table gas-liquid inflow pipeline, an exhaust valve is arranged between the coaxial pipe mounting position and the gas-liquid outflow pipeline, and a pressure gauge 11 and a flow meter 12 are arranged between the coaxial pipe mounting position and the exhaust valve. Wherein the pressure gauge 11 adopts a pressure transmitter CYYZII-H-I6-AI-I9-8-G, and the flow meter 12 adopts a flow sensor FD-Q20C. The low-pressure valve 4, the high-pressure valve 5 and the exhaust valve 6 are all pneumatic angle seat valves JL 2000-1.
The utility model is mainly divided into two parts. The first part is a control console, which is mainly used to control gas valves and liquid valves, so as to control the inlet and outlet of low-pressure gas, high-pressure gas and liquid. The console also has a display panel for displaying the pressure of the gas and liquid to be discharged and discharged, providing visual results for accurately judging whether the coaxial tube is a qualified member.
The second part is a workpiece table which is mainly used for connecting the coaxial pipe with the air inlet and the air outlet of the detection equipment, so that the coaxial pipe is cleaned and detected.
The method can simultaneously carry out the steps of cleaning, blow-drying, plugging detection and leakage detection on 6 coaxial tubes, and takes 90 seconds. The implementation method comprises the following steps:
firstly, 6 coaxial tubes to be detected are connected with a manual valve on one side and a flowmeter on the other side in a mode illustrated by a diagram 2. After the connection is finished, the manual valve of the workpiece table is opened, gas and liquid can flow into the workpiece table from the operation table, and then the utility model is started.
