Further, described valve seat section is wedge shape, and be inclined-plane with spheroid one end of fitting, inclined-plane is provided with convex stupefied, and convex stupefied end face is sphere, fits with spherome surface.
Preferably, described valve seat lock ring is FERRULETYPE nut.
Further, described valve seat supporting inwall is provided with circular groove D.
The utility model compared with prior art has following beneficial effect: seat design is become demountable structure, easy accessibility, and effectively prevent the damage to axial sealing ring in disassembly process, improves working life, and easy to maintenance, and maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is the partial sectional view that the utility model is assemblied in ball valve;
Fig. 2 is the enlarged view at I place in Fig. 1;
In figure: the supporting of 1-valve body, 2-spheroid, 3-valve seat, 4-valve seat, 5-valve seat lock ring, 6-convex stupefied, 7-valve seat back-up ring, 8-locating stud, 9-lip-type packing, 10-circular groove A, 11-graphite rope, 12-helical spring, 13-looping pit B, 14-circular groove C, 15-gasket seal, 16-pin-and-hole, 17-circular groove D.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As Fig. 1, shown in Fig. 2, a kind of Collapsible top dress ball valve base structure disclosed in the utility model, comprise valve body 1, valve seat supporting 3, valve seat 4, valve seat lock ring 5 and spheroid 2, valve seat 4 one end and valve seat are supported 3 one end and are connected by valve seat lock ring 5 and are arranged between valve body 1 and spheroid 2, valve seat 4 the other end is inclined-plane, inclined-plane has convex stupefied 6, convex stupefied 6 end faces and spheroid 2 are fitted, it is stepped that valve seat supports 3 the other ends, be located in valve body 1, comprise first step, second step and the 3rd step, first step is circumferentially provided with pin-and-hole 16, valve seat back-up ring 7 is fixed on first step by locating stud 8, second step is provided with lip-type packing 9, ensure No leakage between valve seat supporting 3 and valve body 1, three-stepped shaft is provided with circular groove A10 to face, graphite rope 11 is provided with in circular groove A10, 3rd step sagittal plane is provided with looping pit B13, the helical spring 12 axially installed is provided with in looping pit B13, and helical spring 12 is in compressive state, one end end face that valve seat supporting 3 is connected with valve seat 4 is provided with circular groove C14, and outer peripheral surface is provided with screw thread, is provided with gasket seal 15 in circular groove C14, valve seat supports 3 inwalls and is also provided with circular groove D17.
The utility model assembly and disassembly methods is as follows: during assembling, first valve seat supporting 3, lip-type packing 9, graphite rope 11, valve seat back-up ring 7, locating stud 8, helical spring 12, gasket seal 15 are assembled and be encased in valve body 1 together, then 3 a little distances are supported by tooling shaft to strutting two valve seats, again valve seat 4 being overlapped upper valve base lock ring 5 and fitting tightly with spheroid 2 loads in valve body 1, after calibrating position, removal frock, and tighten valve seat lock ring 5, make valve seat 4 press seal pad 15 ensure that valve seat 4 and valve seat support the sealing between 3, complete the assembling of spheroid 2 and valve seat 4.During dismounting, first unscrew valve seat lock ring 5, make it to depart from completely valve seat supporting 3, by tooling shaft to strutting two valve seats supporting 3 a little distances, realizing valve seat 4 and valve seat and supporting 3 be separated, at this moment, valve seat lock ring 5, valve seat 4 can be taken out valve body 1 with spheroid 2 simultaneously.As can be seen here, in the disassembly process of spheroid 2 and valve seat 4, needing to strut valve seat, to support 3 axial distances very little, effectively can avoid lip-type packing 9 in disassembly process, occur wearing and tearing like this, ensure that the sealability of ball valve, improve the working life of ball valve.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
