Close the plastic project for adding glass.
And needle mounting structure used at present is complicated, cannot be guaranteed the stability of needle in use, in turn
Needle using effect is influenced, since traditional needle uses regular length, and then certain trouble is brought to processing.For this purpose, we
It is proposed a kind of wear-resisting needle being easily installed.
Invention content
It is simple in structure the main purpose of the present invention is to provide a kind of wear-resisting needle being easily installed, facilitate installation and tears open
It unloads, facilitates adjustment needle length, and then improve processing efficiency, it is easy to operate, and can ensure that needle is stable, ensure needle
Safety has air guiding function, convenient for ensureing airflow balance inside needle, can effectively solve the problems in background technology.
To achieve the above object, the technical solution that the present invention takes is：
A kind of wear-resisting needle being easily installed, including valve needle cover and needle, the needle are located inside valve needle cover, the valve needle cover
Bottom end is welded with screw nipple, flow-guiding channel is equipped with inside the valve needle cover, and flow-guiding channel both sides buckle has assigned cone
Shape support column, the taper support column are connected through valve needle cover inner cavity and with valve needle cover lateral wall, the flow-guiding channel bottom
End is fixed to be communicated with conduit, and conduit is through being threadedly coupled tube cavity.
Further, needle bottom end spiral is mounted on inside the valve opening installed between valve needle cover madial wall, and valve
Hole bottom end is provided with electric telescopic rod, and the electric telescopic rod other end is welded on the protection pedestal table of flow-guiding channel top installation
Face.
Further, it is welded with damping spring between the valve opening and protection pedestal, and damping spring is located at electric expansion
Bar both sides.
Further, the needle outer surface is coated with polyurethane wear resistant layer.
Compared with prior art, the present invention has the advantages that：
1, compressive state is generated by using electric telescopic rod cooperation damping spring, can effectively ensure that needle is stable, from
And make needle retraction valve needle cover inner cavity, and then it is conveniently adjusted needle length, be conducive to improve processing efficiency, it is easy to operate.
2, it is used by using the flow-guiding channel of tubes fit top connection, convenient for the gas inside valve needle cover is exported,
Convenient for ensureing airflow balance inside needle.
3, by using screw nipple, it is convenient for needle integral installation in body surface.

Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
As shown in Figs. 1-2, a kind of wear-resisting needle being easily installed, including valve needle cover 1 and needle 2, the needle 2 are located at valve
Inside needle guard 1,1 bottom end of the valve needle cover is welded with screw nipple 3, and flow-guiding channel 8 is equipped with inside the valve needle cover 1, and
8 both sides of flow-guiding channel buckle has assigned taper support column 10, and the taper support column 10 is through 1 inner cavity of valve needle cover and and needle
It covers 1 lateral wall to be connected, 8 bottom end of the flow-guiding channel is fixed and is communicated with conduit 9, and conduit 9 is through in screw nipple 3
Chamber.
Wherein, 2 bottom end spiral of the needle is mounted on inside the valve opening 5 installed between 1 madial wall of valve needle cover, and valve opening
5 bottom ends are provided with electric telescopic rod 11, and 11 other end of the electric telescopic rod is welded on the protection base of 8 top of flow-guiding channel installation
7 surfaces of seat.
Wherein, it is welded with damping spring 6 between the valve opening 5 and protection pedestal 7, and damping spring 6 is located at electric expansion
11 both sides of bar.
Wherein, 2 outer surface of the needle is coated with polyurethane wear resistant layer 4.
It should be noted that the present invention is a kind of wear-resisting needle being easily installed, when work, by the way that needle is assigned into valve
Inside the valve opening 5 of 1 madial wall of needle guard welding, so that needle 2 is attached with valve needle cover 1, due to being welded in 1 bottom end of valve needle cover
Connect screw nipple 3, convenient for by needle integral installation in body surface, it is easy to operate, and in 3 inner cavity of screw nipple through leading
