Wherein, 1, valve body, 2, cylinder body, 3, valve rod, 4, spool, 5, valve seat, 6, alignment pin, 7, valve seat cylinder, 11, admission chamber；12, sap cavity is gone out.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is further described.These accompanying drawings are the schematic diagram of simplification and basic structure of the present utility model are described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
As shown in Figure 1, a kind of shock resistance is surged choke valve, including valve body 1, cylinder body 2 and valve rod 3, it is provided with for installing the installation cavity of cylinder body 2, admission chamber 11 and going out sap cavity 12 in valve body 1, installation cavity and go out sap cavity 12 and be separately positioned on the both sides of admission chamber 11 port of export, the outlet of installation cavity is oppositely arranged with the import going out sap cavity 12.The centrage of installation cavity and admission chamber 11 overlaps.
Cylinder body 2 is arranged in installation cavity, and the lower end of cylinder body 2 extends in admission chamber 11, and the section of stretching out of cylinder body 2 lower end accounts for the 1/3～3/4 of admission chamber 11 diameter；In the present embodiment, the preferably section of stretching out accounts for the 3/5 of admission chamber 11 diameter, and cylinder body 2 offers rod chamber, valve rod 3 is removably set on bar intracavity, the lower end of valve rod 3 is stretched out bottom the section of stretching out of cylinder body 2, and the lower end of valve rod 3 is provided with spool 4, and spool 4 can be formed to seal with the import going out sap cavity 12 and coordinate.
Going out sap cavity 12 import department and offer step annular groove, step annular groove is provided with valve seat 5, offer core bore in valve seat 5, spool 4 makes in inserting core bore to be formed between spool 4 with valve seat 5 to seal to coordinate.For improving valve seat 5 mounting stability, below valve seat 5 go out sap cavity 12 in be provided with valve seat cylinder 7, valve seat cylinder 7 upper end offsets with valve seat 5, and valve seat cylinder is arranged down in bringing out sap cavity 12 7 times and cap, descends also cap to be fixed on out in sap cavity 12 by valve seat cylinder 7.
The upper end of valve seat 5 is provided with multiple alignment pin 6, offers several and insert in each pin-and-hole for the pin-and-hole coordinated with alignment pin 6, each alignment pin 6 upper end below the section of stretching out of cylinder body 2.Each alignment pin 6 can be effectively improved the section of the stretching out stability at admission chamber 11, the impact of current in opposing admission chamber 11.
During choke valve path, valve rod 3 and the spool 4 water in bar intracavity, admission chamber 11 flow through and enter out below the section of stretching out in sap cavity 12；When choke valve cuts out by needs, valve rod 3 moves down, and band movable valve plug 4 enters in the core bore of valve seat 5, thus cut off the current entered out in sap cavity 12, realizing choke valve to close, the section of stretching out provides strong radial direction to support for spool 4, and alignment pin 6 improves the section of stretching out stability in admission chamber 11.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff can carry out various change and amendment completely in the range of without departing from this utility model technological thought.The content that the technical scope of this utility model is not limited in description, it is necessary to determine its technical scope according to right.
