Plugging during emergency operation of heat pipeline
The pipe water plugging includes a body, a washer, a valve and a nut, one end of the body is sealed, the other end is provided with a valve, and the valve is glued together with the body, which is characterized in that the inner wall of one end of the body is provided with a gasket; It can block the valve, and the valve will not pop and fall when pumping, so as to improve the service life of water shutoff; It has a sophisticated transition, no dead corner, strong pressure resistance, and is not easy to crack after pressurization and inflation; A reinforcing belt is arranged on the body to improve the compressive strength of the body; It is equipped with a new sealing gasket, which has good sealing performance, and the gas is not easy to leak after inflation; The specification and size are serialized, which is easy to fit with the inner wall of the pipeline. It can be widely used in pressure test, closed water test, maintenance or dredging operations of domestic water pipes, fire water pipes, sewer pipes, sewage pipes, etc. to block the water flow and complete the plugging of the pipeline; It can also be used to block the air flow pipeline during the emergency operation of gas and heat pipelines. The thickness of the closed water test is average and the airtightness is strong. The valves pass through the upper part of the hot press vulcanizer by means of lap joint to make the valves more solid and ensure the number of applications. 2. In the closed water experiment, the small one can be inflated with an air pump and can accept a pressure of 4kg. This refers to the 50-300 water plugging for mold consumption and the large one for processing. The interface must be connected with the air pump to inflate. 3 The closed water test can be used repeatedly, and it should be stored in a ventilated and cool place.
