Abstract
The utility model discloses a kind of gate valve for convenience detach, belong to valve field.This gate valve for convenience detach comprises valve body, valve rod, valve plate, and valve plate both sides all seal and are fitted with valve seat, and valve seat is divided into outer seat and interior valve seat; Described interior valve seat longitudinal cross-section is provided with spring eye, and lateral cross section is provided with fixed groove, and on one end of valve plate, be also provided with elastic buckles, the one end away from valve plate is provided with limit dais; Described outer seat longitudinal cross-section is provided with tapped blind hole, is screwed with interior valve seat; Described valve body is provided with the boss with fixed groove adaptation on interior valve seat.Adopt the utility model to make the dismounting of gate valve be more prone to realize, only need change the outer seat of damage, save financial cost.
Description
Technical field
The utility model relates to valve field, specifically a kind of gate valve for convenience detach.
Background technique
Gate valve makes open-shut device with flashboard and move along valve seat axes normal direction, to realize the valve of switching motion.Gate valve can only standard-sized sheet and complete shut-down, and open-shut device is flashboard, moving direction and flow direction perpendicular, square I-shaped gate valve two sealing surfaces form wedge shapes, key groove is different with valve parameter.
In the prior art, the valve seat of most gate valve processes through butt welding processing in the chamber of valve body, do not have special instrument to be very difficult to take out, and once there is poorly sealed defect, many users only have replacing gate valve, then scrap with the gate valve changed.The economic loss caused is large, cost of idleness.
Model utility content the utility model aims to provide a kind of gate valve for convenience detach, is intended to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of gate valve for convenience detach, comprise valve body, valve rod, valve plate, it is characterized in that, valve plate both sides all seal and are fitted with valve seat, and valve seat is divided into outer seat and interior valve seat; Described interior valve seat longitudinal cross-section is provided with spring eye, and lateral cross section is provided with fixed groove, and on one end of valve plate, be also provided with elastic buckles, the one end away from valve plate is provided with limit dais; Described outer seat longitudinal cross-section is provided with tapped blind hole, is screwed with interior valve seat; Described valve body is provided with the boss with fixed groove adaptation on interior valve seat.
Further, cavity is left between described interior valve seat and valve body.
Further, interference fit between described outer seat and valve body, and be provided with sealing O shape circle.
Further, described elastic buckles be Uniaxial Compression can Flexible Reset button.
The beneficial effects of the utility model are:
One, valve seat is divided into interior outer seat, and strengthen interchangeability of parts, outer seat becomes metal hard-sealing with valve plate, easily weares and teares, and after outer seat generation wearing and tearing are scrapped, interior valve seat still can continue to use, and only need change outer seat, saves financial cost.
Two, spring is provided with between interior valve seat and outer seat, cavity is left between interior valve seat and valve body, after seal failure, unclamp the screw between interior valve seat and outer seat, under elastic force effect, boss a certain amount of ground pressure elasticity button, interior valve seat moves to cavity, interior valve seat is separated with outer seat, and the sealing laminating between outer seat and valve plate loosens, and dismounting valve plate is more prone to.
Three, interior valve seat is provided with annular fixed groove, works in coordination with the boss on valve body, fixes with limit dais and elastic buckles, and assembling is simple, easily realizes.
Four, split type valve seat processing is more simple, is applicable to produce in enormous quantities.
Accompanying drawing explanation
Fig. 1 is the gate valve structure schematic diagram for convenience detach that the utility model provides.
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Mark in figure: 1 be valve body, 2 be valve plate, 3 be interior valve seat, 4 be outer seat, 5 be boss, 6 be elastic buckles, 7 be spring, 8 be screw, 9 be cavity, 10 be valve rod, 11 for sealing O shape circle, 12 be limit dais.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of gate valve for convenience detach, comprises valve body 1, valve rod 10, valve plate 2, it is characterized in that, valve plate 2 both sides all seal and are fitted with valve seat, and valve seat is divided into outer seat 4 and interior valve seat 3; Described interior valve seat 3 longitudinal cross-section is provided with spring eye, and lateral cross section is provided with fixed groove, and on one end of valve plate 2, be also provided with elastic buckles 6, the one end away from valve plate 2 is provided with limit dais 12; Described outer seat 4 longitudinal cross-section is provided with tapped blind hole, fixes with interior valve seat 3 screw 8; Described valve body 1 is provided with the boss 2 with fixed groove adaptation on interior valve seat 3.Cavity 9 is left between described interior valve seat 3 and valve body 1.Interference fit between described outer seat 4 and valve body 1, and be provided with sealing O shape circle 11.Described elastic buckles 6 be Uniaxial Compression can Flexible Reset button.
When needs are dismantled, unclamp the screw 8 between interior valve seat 3 and outer seat 4, under elastic force effect, boss is to axial direction a certain amount of ground pressure elasticity button 5, interior valve seat 3 is made to produce certain displacement to cavity 9, thus interior valve seat 3 is separated with between outer seat 4, the sealing between outer seat 4 and valve plate 2 is fitted and is loosened.Adopt the utility model to make the dismounting of gate valve be more prone to realize, only need change the outer seat 4 of damage, save financial cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (4)
