Fore filter includes the filter screen connecting with spool and the plug that connect positioned at filter screen side with valve body screw thread.
By using above-mentioned technical proposal, industrial pipeline is due to the complexity of medium, and if medium is not pure, there are particles
Object easily causes sealing surface to crush when medium is trapped in cut-off valve sealing surface, and the filter device by being equipped with can be effective
Filter out the impurity of part, to protect corresponding sealing surface, when valve rod rotation, bottom resists spool, thus in sealing surface
Under the action of effectively water can be prevented to pass through, achieve the effect that sealing.
Further setting：The valve body includes the feeding inlet connecting with pipeline, the cavity being equipped with positioned at feeding inlet, is located at
Discharge port below cavity and the end socket above cavity, the valve rod are connect with end socket inner thread.
By using above-mentioned technical proposal, the valve body of such setting can effectively make water flow after feeding inlet passes through on
It rises, is come out to reach discharge port, and the substances such as impurity can be effectively trapped in lower section, cut-off valve chest uses single flow Y
Shape design, the two constitute jointly new hull and valve combination, convenient for stopping impurity.
Further setting：The valve rod, which is located in end socket, is surrounded by sealant tape.
By using above-mentioned technical proposal, the sealant tape being equipped with can effectively reduce water and receive pressure from valve rod
Outside leak is influenced, to guarantee whole sealing effect.
Further setting：The outer wall of the cavity and end socket is equipped with along side, and described be equipped with along side tightens bolt, described
Tighten bolt both ends be equipped with tighten nut.
By using above-mentioned technical proposal, be equipped with along side and tighten bolt and can effectively facilitate whole disassembly, from
And convenient for the cleaning to internal impurity, it is easily installed.
Further setting：Sealing rubber pad is additionally provided on the end socket inner wall.
By using above-mentioned technical proposal, the sealing rubber pad being equipped with can also effectively guarantee that entire valve body is water-tight,
To guarantee entire use.
Further setting：The valve stem tip is additionally provided with rotation handwheel.
By using above-mentioned technical proposal, the rotation handwheel being equipped with controls opening for entire shut-off valve convenient for users to rotation
It closes.
In conclusion the invention has the advantages that：It is can effectively protect the sealing surface of shut-off valve, extends and uses the longevity
Life improves the reliability of system control, and cut-off valve chest is designed using single flow Y shape, and plug is using bolt or screw thread and valve body
Connection, it is convenient periodically to disintegrate, remove filtrate.
