Abstract
The utility model discloses a kind of ball valve seat, it is characterized in that, comprise the circumferential body that center is provided with valve seat endoporus, is circular arc with the surface of contact being polymerized ball on the upside of circumferential body, sealing configuration linear with polymeric spherical; The bottom of valve seat endoporus is provided with stiffening rib.What the utility model was effective and reasonable avoid, and high-pressure fluid medium washes away ball valve seat Drawing cone face and is polymerized the upper and lower opening and closing of ball clashes into the damage caused; The utility model has the advantage of convenience quick for installation, simple and reasonable, safe and reliable, durable.
Description
Technical field
The utility model relates to a kind of ball valve seat, is specifically related to a kind of valve seat construction of fracturing unit truck hydraulic end of plunger pump assembly accessory.
Background technique
Valve body and valve seat are the component of the important component part of pump, the unlatching of its function to be exactly plunger pump control under the strong state of work suction side and exhaust end with close the supercharging and lifting rate that realize pump, and plunger pump major function is suction side from sucking low-pressure fluid and being converted into the device that high-pressure liquid discharges from exhaust end; Because valve body and valve seat bear the washing away of the high-pressure fluid medium of mud, gravel, acid solution etc., burn into wearing and tearing for a long time, the impact toughness of valve seat entirety, wear resistance are great tests, and its durable will affect the service time of plunger pump simultaneously; The taper sealing of valve body and valve seat and valve seat and clack box is all coordinate by tapered surface the function realized in hard sealing.The damage main cause of current valve body and valve seat has: valve body and valve seat are by the bad inefficacy of pressure liquid erosive wear; Valve rubber buffering, seal failure cause the valve body conical surface directly to clash into the valve seat conical surface and cause valve seat damage; Seat hardness layer is dark not, easily produces wear out failure; The lost of life that valve seat body material property instability causes.This this factor has had a strong impact on carrying out smoothly of well head fracturing work, has become each elephant pressure break company the working life of improving valve body and valve seat and to have enhanced productivity, create a challenge of high benefit.
Summary of the invention
What the utility model needed solution is the conventional valve seat construction problem that working life is low in oil field compression fracture operation, efficiency is not high.
In order to solve the problem, the technical solution of the utility model is to provide a kind of ball valve seat, it is characterized in that, comprises the circumferential body that center is provided with valve seat endoporus, be circular arc with the surface of contact being polymerized ball on the upside of circumferential body, sealing configuration linear with polymeric spherical; The bottom of valve seat endoporus is provided with stiffening rib.
Preferably, the outer rim of described circumferential body is provided with seal groove.
Seal ring is placed in the seal groove of ball valve seat, ball valve seat entirety is placed on clack box 1: 16 tapered hole sealing surface, polymerization ball is placed in ball valve seat upper surface, ball-type centralizer is positioned on polymerization ball, spherical centralizer is placed in the positioning guide hole of spring bracket one end, the middle Compress Spring that uses controls to open, closure function, liner is placed on spherical centralizer positioning boss, buffer function is played during work, hand-held one end spring bracket is from sucking gland end endoporus with downward-sloping suitable angle, small boss rank, spring bracket one end are made to aim in Compress Spring in snare, and make spherical centralizer guide rod be placed in spring bracket positioning guide hole, grasp spring bracket one end force that tilts fast when inwardly pushing away and be pressed downwardly onto certain position, under the active force of cone compresses spring, make the tapered portion of spring bracket and clack box sap cavity inner cone wall match, the boss step sucking gland one end inserts in the positioning hole of spring bracket, restriction spring bracket produces displacement in work.
The beneficial effects of the utility model are: what ball type valve stand structure was effective and reasonable avoid, and high-pressure fluid medium washes away ball valve seat Drawing cone face and be polymerized the upper and lower opening and closing of ball clashes into the damage caused; The utility model has the advantage of convenience quick for installation, simple and reasonable, safe and reliable, durable.
Accompanying drawing explanation
The structural representation of a kind of ball valve seat that Fig. 1 provides for the utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the side view of Fig. 2;
Schematic diagram when Fig. 4 is the utility model installation.
Embodiment
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As Figure 1-3, being the structural representation of a kind of ball valve seat that the utility model provides, comprising the circumferential body 1-1 that center is provided with valve seat endoporus 1-2, is circular arc with the surface of contact being polymerized ball 3 on the upside of circumferential body 1, and is polymerized ball 3 and forms linear sealing structure; The bottom of valve seat endoporus 1-2 is provided with stiffening rib 1-3.The outer rim of circumferential body 1-1 is provided with seal groove 1-4.
When the utility model is installed as shown in Figure 4, seal ring 2 is placed in the seal groove 1-4 of ball valve seat 1, ball valve seat 1 entirety is placed on clack box 1: 16 tapered hole sealing surface, polymerization ball 3 is placed in ball valve seat 1 upper surface, ball-type centralizer 4 is positioned on polymerization ball 3, spherical centralizer 4 is placed in the positioning guide hole of spring bracket 7 one end, the middle Compress Spring 6 that uses controls to open, closure function, liner 5 is placed on spherical centralizer 4 positioning boss, buffer function is played during work, hand-held one end spring bracket 7 is from sucking gland 8 end endoporus with downward-sloping suitable angle, small boss rank, spring bracket 7 one end are made to aim in Compress Spring 3 in snare, and make spherical centralizer 4 guide rod be placed in spring bracket 7 positioning guide hole, grasp spring bracket 7 one end force that tilts fast when inwardly pushing away and be pressed downwardly onto certain position, under the flexible active force of cone compresses spring 6, make the tapered portion of spring bracket 7 and clack box sap cavity inner cone wall match, the boss step sucking gland 8 one end inserts in the positioning hole of spring bracket 7, restriction spring bracket 7 produces displacement in work.
