Abstract
The utility model provides a fixed ball valve with a long transportation pipeline, comprising a valve body, a valve cover, a valve seat, a valve core and a valve rod. The ball valve is characterized in that the end surface of the valve body, butted with the valve seat, is provided with a ring-shaped installing groove which is axially arranged around the valve body; the installing groove is internally provided with a valve seat spring; one end of the valve seat spring is butted with the valve seat, and the other end thereof is butted with the groove bottom of the installing groove. When the fluid medium flows to the downstream side from the upstream side in a valve cavity, and the pressure in the ball valve increases excessively, the valve seat at the upstream side moves axially along the valve; the valve seat spring is compressed so as to play roles in buffering and reducing pressure, and simultaneously the upstream side generates pressure difference and pushes the valve seat to the valve core so as to achieve tight sealing of the upstream; when the pressure of the downstream side is excessively large, the pressure difference between the inner cavity of the valve core and the valve body leads the valve seat and the valve core to be separated from each other by overcoming the acting force of the valve seat spring, at the moment, the pressure in the valve cavity is released to a fluid outlet channel in the valve body, and after the pressure is released, the valve seat and the valve core are tightly sealed again under the effect of the valve seat spring.
Description
Technical field
The utility model relates to a kind of ball valve, and especially a kind of long-distance transport pipes are spherical ball valve fixedly.
Background technique
Long-distance transmission pipeline is referred to as to call long-distance transport pipes, carries liquid or gas with pipeline, and its cost is 1/3 of railway transport, and is seaborne 2/3, and the cheap of cost makes it obtain over 100 years to promote rapidly and develop nearly one.The valve that uses on the long-distance transport pipes is referred to as to call pipeline valve, wherein valve is the pipeline ball-valve that is called as of ball valve, because in pipeline transportation, medium in the pipeline generally all is in the state of High Temperature High Pressure, and when ball valve is in closed condition, accumulate in the spool body cavity, and the medium between spool and valve seat can raise unusually because of variation of temperature causes the valve core cavity pressure, might cause valve body blast or valve body to go out external when serious.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of valve pocket internal pressure that can make to discharge automatically, and the fixing spherical ball valve of the long-distance transport pipes that reduce the operation moment of torsion.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of long-distance transport pipes are spherical ball valve fixedly, include valve body, valve gap, valve seat, spool and valve rod, advance along horizontal formation in the valve body, the outlet fluid passage, spool also is communicated with to advance in the middle part of being arranged in the valve body, the outlet fluid passage, lay respectively in the valve body on the spool outer wall, the sealing surface and the sealing surface of seat formation at place, outlet fluid passage are sealed and matched, the end that cooperates with seal spool on the valve seat advance in right the other end sealing surface and the valve body, outlet valve body sealing surface closely formation is sealed and matched, valve gap is fixed on the valve body upper-end surface, valve rod vertically passes the valve gap top, valve rod lower end and spool interlock, it is characterized in that: the mounting groove that is provided with the annular that axially is provided with around valve body on the described valve body with the inconsistent end of valve seat, be installed on seating spring in the mounting groove, one end and the valve seat of seating spring are inconsistent, and the other end and mounting groove bottom land are inconsistent.
Adopt technique scheme, flowing medium flows to the outlet fluid passage from the inlet fluid passage in the valve pocket, when the pressure at inlet fluid passage place in the ball valve rises too high, inlet fluid passage place valve seat will be along the ball valve axial motion, seating spring is compressed, played the effect of buffering and decompression, inlet fluid passage place will produce pressure difference and valve seat will be pushed to the tight seal that spool reaches the inlet fluid passage simultaneously; When the pressure at place, outlet fluid passage is excessive, the active force that pressure difference in valve core cavity and the valve body will overcome seating spring breaks away from valve seat and spool, at this moment the outlet fluid passage of the pressure in the valve pocket in valve body discharges, after the row pressure the effect lower valve base of seating spring again with the spool tight seal.
Of the present utility modelly further be set to: described valve body is provided with bleeder, and this bleeder is the screw that is provided with the other end that it is right that valve gap is fixed an end on the valve body, and the screw place is provided with the screw that is sealed and matched with it.
Adopt technique scheme, make valve be under the closed condition, can pass through the medium of bleeder emptying valve core cavity, thereby block fluid fully from the valve two ends.Especially for a long time use pipeline ball-valve situation the time, but throttle down and washes and discharges the sediments in the valve body by bleeder.
Of the present utility modelly further be set to: the outside of end, described valve body upper valve base place is provided with introduction valve, and the outside with the inconsistent end of valve rod on the valve gap is provided with introduction valve again.Wherein, be provided with fireproof pad with the inconsistent sealing surface place of valve body on the described valve seat, be provided with fireproof pad with the inconsistent sealing surface place of valve gap on the valve rod.
Adopt technique scheme, the introduction valve that install respectively end, valve body upper valve base place and end, valve gap upper valve rod place can be used to when the trace leakage takes place pipeline ball-valve, the injection sealing compound carries out auxiliary seal in valve body, and in particular cases also can valve seat and valve rod region be lubricated and wash at other, to keep its plot.In addition, the burning things which may cause a fire disaster of barrier valve inside and outside portion can be effectively played in being provided with of fireproof pad, plays the function of flameproof protection.
Below in conjunction with accompanying drawing the utility model is further described:
