Between the valve seat of both sides and the valve plate that is arranged on the valve rod and cause valve plate around own axis for driving stem
The drive mechanism that passage is intercepted or opened by oscilaltion campaign, wherein valve seat include the internal through hole for having and being connected with passage
Seat body, valve rod and valve plate form feed screw nut's structure, and particularly, valve seat also includes setting around its circumference positioned at seat body interior
The mounting groove put, it is arranged in mounting groove and causes valve seat and passway junction that there is the tension ring of tensioner trend.
Preferably, between valve seat periphery and passway inwall by multiple O-ring sealed sets, the plurality of O-ring along
The length direction distribution of valve seat.
Further, mounting groove has an one or more, and tension ring is corresponded with mounting groove and set, and mounting groove with it is O-shaped
Be staggered bit distribution between circle.
Preferably, the inwall three of the inwall of tension ring, the through-hole wall of seat body and passage flushes setting.It is easy to flow
The quick circulation of body.
According to one of present invention specific implementation and preferred aspect, flat gate valve also include being arranged on valve seat and passway it
Between elastic component.Stress suffered by valve seat is effectively decomposed, so as to extend the service life of valve seat.
Specifically, elastic component is wavy spring.
It is also close including being separately positioned on valve seat according to another specific implementation of the present invention and preferred aspect, flat gate valve
The guide plate of valve plate end.
Preferably, guide plate is extended up and down respectively along the end of valve seat, when the downward close passage of valve plate
When, both sides guide plate is fitted in the both sides of valve plate.
Further, the bottom that flat gate valve also includes being used to for both sides to be located at the guide plate below the end of valve seat is mutually solid
Fixed connection and the protection board that can prevent valve plate from being touched with valve body.The depth of parallelism of both sides guide plate is not only ensure that, and is prevented
Valve plate touches with valve body.
In addition, drive mechanism includes handwheel, bearing block, the axle for being driven by handwheel and being arranged on by bearing on bearing block
Set, for by the bearing pin of axle sleeve locking relative with drive rod.
Due to the implementation of above technical scheme, the present invention has the following advantages that compared with prior art:
Setting of the invention by tension ring so that the sealing of valve seat and valve body is strong, reduces the generation of leakage accident, simultaneously
It is simple in construction, it is easy to implement, and cost is low.

Embodiment
As shown in figure 1, the flat gate valve of the present embodiment, it includes valve body 1, valve rod 2 and the inside both sides passway of valve body 1
The valve seat 3 of 10 phase sealed sets, between both sides valve seat 3 and the valve plate 4 that is arranged on valve rod 2 and for driving stem 2
Around own axis so that the drive mechanism 5 that passage is intercepted or opened by the oscilaltion campaign of valve plate 4, wherein valve rod 2 and valve
Plate 4 forms feed screw nut's structure.
Specifically, valve seat 3 includes the internal through hole k for having and being connected with passage t seat body 30, in seat body 30
Portion around its circumferentially disposed mounting groove 31, be arranged in mounting groove 31 so that valve seat 3 with the junction of passway 10 there is tensioner to become
The tension ring 32 of gesture.
Further, valve seat 3(Seat body 30)By multiple sealed sets of O-ring 6 between periphery and the inwall of passway 10,
