The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of no hydrops inner-cavity structure gate valve, including hand
Wheel 1, the handwheel 1 are flexibly connected by valve stem nut with valve rod 41, and the moving up and down with ovable valve stem 41 of handwheel 1 is rotated, thus
Moving up and down for valve plate 4 is driven, and then achievees the purpose that switch gate valve, 1 lower end of handwheel is connected with valve deck 2, described
Valve deck 2 is fixedly connected with valve body middle chamber 3 by fastening bolt 9, and valve body middle chamber 3 is for storing valve plate 4, when making to open gate valve, valve
Plate 4 is moved in valve body middle chamber 3, and 3 lower end of valve body middle chamber is communicated with valve body 5, and the 5 middle part activity of valve body, which runs through, valve plate
4, the valve plate 4 is used to block the flowing of water flow, and 4 upper end of valve plate is fixedly connected by valve rod 41 with handwheel 1, the valve body
5 middle parts inner cavity are provided with valve seat 8, and the valve seat 8 is fixed for valve plate 4, and when gate valve is closed, valve plate 4 is in contact with valve seat 8, valve
4 outer end of plate is plugged in the groove of valve seat 8, and the valve body 5 is fixedly connected with strainer 6, and the strainer 6 is for filtering stone silt
Equal impurity, water flow flows from left to right, and when through filter screen 6, impurity is blocked by strainer 6, and water flow is passed through from valve body 5, the valve
5 inner cavity lower end of body is provided with dirt discharge groove 71, and accumulation of the dirt discharge groove 71 for impurity is discharged, and 71 lower end of dirt discharge groove is communicated with
Blowdown flange 7, before the impurity under being intercepted by strainer 6 is deposited in strainer 6, due to the effect of gravity, impurity is deposited in the bottom of strainer 6
It in portion's dirt discharge groove 71, is flowed out outside valve body 5 by blowdown flange 7, gear is fixedly connected with by spring 51 in the middle part of 5 inner cavity of valve body
Plate 52, the spring 51 are in compressive state always, and surface is equipped with sealing material at the 5 inner cavity central slot of valve body, works as valve
When plate 4 is downwardly into 5 inner cavity central slot of valve body, increase leakproofness, the interaction of 8 groove of the baffle 52 and valve seat, energy
Enough guarantee that baffle 52 under the elastic force effect of spring 51, will not remove outside valve seat 8,52 upper end of baffle is fixedly connected with movement
Block 53, when valve plate 4 moves up, and valve is opened, baffle 52 is moved outward due to the effect of 51 elastic force of spring, thus band
Dynamic movable block 53 is displaced outwardly, and when movable block 53 is moved to outermost end, 53 outer end of movable block is flushed with 5 inner cavity of valve body,
Prevent valve plate 4 from moving up, valve is opened, and groove occurs in the middle part of valve seat 8, falls into it to make not filter complete impurity
In, it causes impurity to deposit, to keep gate valve tight shut-off, causes drainage, the strainer 6 is located at 8 left side of valve seat, institute
It states dirt discharge groove 71 to be located on the left of strainer 6, when present apparatus installation, moves water flow from left to right, water flow first passes through the filtering of strainer 6
Afterwards, gate valve is flowed out using valve seat 8, the blowdown flange 7 is fixedly plugged in 5 lower end of valve body, blowdown flange 7 and 5 inner cavity of valve body
Connection, when device is when opening work, the switch of closing blowdown flange 7, the impurity for filtering strainer 6 is deposited in dirt discharge groove 71
In, the dirt discharge groove 71 is connected to blowdown flange 7, when gate valve, which is closed, blocks water flow, is opened the valve of blowdown flange 7, is made miscellaneous
Matter is under the action of water flow, from dirt discharge groove 71, is discharged outside brake valve body by blowdown flange 7, the spring 51, baffle 52 and shifting
Motion block 53 is respectively positioned in valve seat 8, and the section of the valve seat 8 is " convex " font, and upper end width is small, and lower end width is big, and lower end is used for
The movement of baffle 52, upper end is used to block moving up for baffle 52, makes movable block 53 when moving up, flush with 5 inner cavity of valve body, described
52 width of baffle is greater than the notch bore of 8 upper end of valve seat, and the width of the movable block 53 is less than the notch bore of 8 upper end of valve seat,
The valve plate 4 is located at right above valve seat 8.
Working principle:
Firstly, gate valve is installed, the case where according to required use, to adjust the switch of gate valve, handwheel 1 is rotated, is come
The raising and lowering of valve plate 4 is adjusted, at work, rotates handwheel 1, drives valve plate 4 to move up by valve rod 41, valve plate 4
It moves up, has cancelled the pressure to movable block 53, movable block 53 makes valve seat 8 and valve since the elastic force of spring 51 moves up
5 inner cavity of body flushes, and later, water flow has from left to right flowing, flows out from valve body 5 through filter screen 6, when water flow flowing, one
A little silt stones etc. are stopped by strainer 6 through filter screen 6, in the dirt discharge groove before being deposited in strainer 6, are flowed from blowdown flange 7 downwards
Out, finally, when needing to separate water flow, handwheel 1 is rotated, valve plate 4 is moved down, valve plate 4 is moved down into the valve of 5 bottom of valve body
When seat 8, movable block 53 is moved down due to the effect of valve plate 4, is stuck in valve plate 4 in valve seat 8.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
