Abstract
A kind of valve seat construction of self-regulation matching gap, comprise valve body and valve seat, valve seat is arranged in valve body, between valve seat and valve body, be provided with cascade fitting surface, cascade fitting surface includes the step of the continuous setting of two above numbers, in cascade fitting surface, be provided with spring, one end of spring is embedded in valve body, and the other end of spring is biased on valve seat.Between valve seat and valve body, be provided with along the axial sliding pair of valve seat, in valve body, be provided with blind hole, the parallel to an axis of the axial and valve seat of blind hole, one end of described spring is arranged in blind hole, and the other end of spring extends to valve base surface.The utility model adopts a plurality of ladder surfaces to coordinate between valve seat and valve body, improved the sealing of valve seat and valve body junction plane, simultaneously, between valve body and valve seat, spring is set, the flexible structure of spring can be adjusted the matching gap between valve body and valve seat, improve the sealability of whole valve, meet the application demand of different occasion lower valves.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to valve, particularly a kind of valve seat construction of self-regulation matching gap that fluid is controlled.
Background technique:
Valve extensive use in fluid is controlled, valve is realized the open and close of pipeline by the sealing of spool and valve seat, realize the control of fluid.In prior art, due to the foozle of spool, valve seat and valve body, while causing valve body assembling, fitting surface not necessarily strictly seals combination, and this sealability to valve has certain influence; And the fitting surface between existing valve seat and valve body, for being rigidly connected, cannot be adjusted matching gap.
Summary of the invention:
The purpose of this utility model is to provide a kind of valve seat construction of self-regulation matching gap, the valve seat that the valve seat construction of described this self-regulation matching gap will solve valve in prior art and valve body coordinate imprecision time cause the bad technical problem of valve seal performance.
The valve seat construction of this self-regulation matching gap of the present utility model, comprise valve body and valve seat, described valve seat is arranged in described valve body, wherein, between described valve seat and valve body, be provided with cascade fitting surface, described cascade fitting surface includes the step of the continuous setting of two above numbers, in cascade fitting surface, is provided with spring, one end of described spring is embedded in valve body, and the other end of spring is biased on valve seat.
Further, between valve seat and valve body, be provided with along the axial sliding pair of valve seat, in valve body, be provided with blind hole, the parallel to an axis of the axial and valve seat of described blind hole, one end of described spring is arranged in blind hole, and the other end of spring extends to valve base surface.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model adopts a plurality of ladder surfaces to coordinate between valve seat and valve body, improved the sealing of valve seat and valve body junction plane, simultaneously, between valve body and valve seat, spring is set, the flexible structure of spring can be adjusted the matching gap between valve body and valve seat, improve the sealability of whole valve, meet the application demand of different occasion lower valves.
Accompanying drawing explanation:
Fig. 1 is the structural representation of the valve seat construction of self-regulation matching gap of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 1, the valve seat construction of self-regulation matching gap of the present utility model, comprise valve body 2 and valve seat 1, described valve seat 1 is arranged in described valve body 2, wherein, between described valve seat 1 and valve body 2, is provided with cascade fitting surface, described cascade fitting surface includes the step of the continuous setting of two above numbers, in cascade fitting surface, be provided with spring 3, one end of described spring 3 is embedded in valve body 2, and the other end of spring 3 is biased on valve seat 1.
Further, between valve seat 1 and valve body 2, be provided with along the axial sliding pair of valve seat 1, in valve body 2, be provided with blind hole, the parallel to an axis of the axial and valve seat 1 of described blind hole, one end of described spring 3 is arranged in blind hole, and the other end of spring 3 extends to valve seat 1 surface.
The working principle of the present embodiment is: between valve seat 1 and valve body 2, adopt a plurality of ladder surfaces to coordinate, improved the sealing of valve seat 1 with valve body 2 junction planes, simultaneously, between valve body 2 and valve seat 1, spring 3 is set, the flexible structure of spring 3 can be adjusted the matching gap between valve body 2 and valve seat 1, improve the sealability of whole valve, meet the application demand of different occasion lower valves.
