Abstract
The present invention relates to the technical field of sealing technology of oil field safety valve, specifically, it is a kind of valve base sealing structure with annular groove, including valve seat, it is axial in the middle part of valve seat to open up a through-hole, the top of valve seat and the top surface of through-hole are connected by an intermediate incline, circumferentially open up an annular groove on valve seat intermediate incline along through-hole, and the annular groove is for storing greasy dirt impurity.It is provided with an annular groove in the oblique sealing surface of valve seat, solve in traditional valve seat construction only have an inclined-plane sealing surface during product use can exist product sand cause steel ball be bonded with valve seat sternly caused by seal failure situation, it ensure that impurity can have good storage space without causing certain stopping state in safety valve, it ensure that the continuity of field operation, ensure job safety.
Description
Technical field
The present invention relates to the technical field of sealing technology of oil field safety valve, specifically, being a kind of valve seat with annular groove
Sealing structure.
Background technology
In current oil, gas well liquid loading operation, high pressure class safety valve is a kind of directly effect Self-resetting valve, relieving mechanism
Spring-loaded ball and ball socket structure, when pressure is more than setting value will automatic overflow, realize to personal safety and high pressure system
The automatic protection of system, high-voltage safety valve base primary seal form is that valve seat is contacted equipped with oblique sealing surface with steel ball at present
Realize sealing.When fluid media (medium) is more than relief valve set pressure, fluid media (medium) can open steel ball, realize pressure release, work as pressure
Less than safety valve setting pressure when, butterfly spring can compress steel ball and be contacted with the oblique sealing surface of valve seat, realize sealing.
However in actual high-voltage operation, due to the difference of test pressure and the complexity of fluid media (medium), in actual job,
Due to there can be related impurities in test(ing) medium, lead between steel ball and sealing element that influence safety valve normally close there are impurity
Seal effect, due to having some other impurity in fluid media (medium), with the extension of usage time, impurity can be deposited in steel ball with
The incline position of valve base of safety valve causes safety valve to cannot achieve normal sealing, not only influences the normal of live pipe-line system
Operation, and hidden danger greatly is brought to the safety of a whole set of manifold system, increase operating risk.
Invention content
It is an object of the present invention to overcome the above-mentioned technical problems, and to provide a kind of valve base sealing structure with annular groove,
Can solve an only inclined-plane sealing surface in existing valve base of safety valve structure can lead to steel during product use in the presence of product sand
Ball be bonded with valve seat it is not tight caused by seal failure situation.
The technical solution for solving above-mentioned technical problem is as follows：
A kind of valve base sealing structure with annular groove, including valve seat, valve seat middle part is axial to open up a through-hole, institute
The top for the valve seat stated and the top surface of through-hole are connected by an intermediate incline, and the intermediate incline and the angle of through-hole top surface are
100~170 °, the vertical height of the intermediate incline is the 1/5~1/4 of valve seat height, the valve seat intermediate incline upper edge
It through-hole and circumferentially opens up an annular groove, the annular groove is for storing greasy dirt impurity.
Preferably, the intermediate incline and the angle of through-hole top surface are 100 °.
It further says, a blow-off pipe is arranged in the lower part of the annular groove, and blow-off pipe is connected to the inside of annular groove, uses
In discharge greasy dirt impurity.
The beneficial effects of the invention are as follows：
The present invention provides a kind of valve base sealing structure with annular groove, it is provided with an annular groove in the oblique sealing surface of valve seat,
Steel ball and valve seat can be led to during product use in the presence of product sand by solving an only inclined-plane sealing surface in traditional valve seat construction
Seal failure situation caused by fitting is not tight, ensure that impurity can have good storage space without causing one in safety valve
Fixed stopping state occurs, and ensure that the continuity of field operation, ensures job safety.By adding on the oblique sealing surface of valve seat
One annular groove of work, under the washing away of fluid media (medium), impurity can be stored in the annular groove of valve seat, not interfere with steel ball and inclined-plane
Leakproofness, and the cleaning valve seat, it can be achieved that timing is easily discharged outside valve seat in greasy dirt impurity, and Operation and Maintenance is convenient, dimension
It repaiies that cost of upkeep is low, is very suitable for applying in wellsite operation in the arrangement of manifold system, application range is wider.
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
