Abstract
The utility model discloses inner sliding sleeve antidetonation choke valve, valve gap (8) is arranged on valve body (1), installing valve rod assembly (3) through valve seat assembly (2), gland (5) in valve body (1), airtight and watertight padding (9) is fixed on valve gap (8) by gland (10)；It is characterized in that: a shockproof back-up ring (4) is installed between valve seat assembly (2) and gland (5), No. two shockproof back-up rings (6) are installed between valve body (1) and gland (5), No. three shockproof back-up rings (7) are installed between gland (5) and valve gap (8), No. four shockproof back-up rings (11) are installed between valve rod assembly (3) and gland (5).The material selection politef of shockproof back-up ring of the present utility model, effectively prevents the internal vibrations produced of fluid scouring internal sliding sleeve throttling valve, reduces noise and fault rate, reduce maintenance, improve work efficiency.
Description
Technical field
This utility model relates to valve, is specifically related to a kind of inner sliding sleeve antidetonation choke valve.
Background technology
At present, in use, when suffering fluid scouring, easily there is inner sliding sleeve and valve in known inner sliding sleeve formula choke valve
Seat seismism, during causing using, valve rod damage even damages, and noise is big, and fault rate is high.
Summary of the invention
The purpose of this utility model is: provides a kind of inner sliding sleeve antidetonation choke valve, can realize inner sliding sleeve choke valve and make
By performance, also can simplify structure, reduce the fluid scouring vibrations to inner sliding sleeve, noise is little, reduces maintenance procedures, improves work effect
Rate.
Technical solution of the present utility model is: this choke valve includes valve body, valve seat assembly, valve rod assembly, gland, valve
Lid, airtight and watertight padding and gland, valve gap is arranged on valve body, installs valve rod assembly through valve seat assembly, gland, seal in valve body
Filler is fixed on valve gap by gland；It is characterized in that: a shockproof back-up ring is installed between valve seat assembly and gland, at valve
No. two shockproof back-up rings are installed between body and gland, No. three shockproof back-up rings are installed between gland and valve gap, in valve rod assembly and pressure
No. four shockproof back-up rings are installed between set.
The utility model has the advantages that: the material selection politef of this shockproof back-up ring, effectively prevent fluid scouring
Internally the internal vibrations produced of sliding sleeve throttling valve, reduce noise and fault rate, reduce maintenance, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is inner sliding sleeve antidetonation throttle-valve structure schematic diagram.
