In order to achieve the purpose, the invention adopts the technical scheme that:
The utility model provides a wear-resisting needle convenient to installation, includes needle cover and needle, the needle is located inside the needle cover, the welding of needle cover bottom has threaded connection pipe, needle cover internally mounted has the water conservancy diversion passageway, and water conservancy diversion passageway both sides buckle has inserted the toper support column, the toper support column runs through in needle cover inner chamber and is linked together with needle cover lateral wall, water conservancy diversion passageway bottom mounting intercommunication has the pipe, and the pipe runs through in the threaded connection intraductal chamber.
Further, the valve needle bottom end is spirally installed inside a valve hole installed between the inner side walls of the valve needle sleeve, an electric telescopic rod is arranged at the bottom end of the valve hole, and the other end of the electric telescopic rod is welded on the surface of a protection base installed at the top end of the flow guide channel.
Further, damping springs are welded between the valve hole and the protection base and located on two sides of the electric telescopic rod.
Further, the outer surface of the valve needle is coated with a polyurethane wear-resistant layer.
Compared with the prior art, the invention has the following beneficial effects:
1. Through utilizing electric telescopic handle cooperation damping spring to produce compression state, can effectively guarantee that the needle operation is stable to make needle retraction valve needle cover inner chamber, and then be convenient for adjust needle length, be favorable to improving machining efficiency, convenient operation.
2. The guide pipe is matched with the flow guide channel communicated with the top end for use, so that gas inside the valve needle sleeve can be guided out conveniently, and the balance of gas amount inside the valve needle can be ensured conveniently.
3. By using the threaded connection pipe, the valve needle can be conveniently and integrally installed on the surface of an object.
