Abstract
The utility model relates to a full-floating flat gate valve. A valve handle and a flashboard are arranged inside the valve body and the flashboard is connected with the underside of the valve handle through a T-shaped fastener. The utility model is characterized in that a limit block is arranged on the valve handle and a limit plane A capable of limiting the limit block axially is arranged on the wall of the side port of the inner cavity of the valve body. When the valve is closed, the limit block on the valve handle contacts the limit plane A on the valve body. The flashboard is suspended on the limit plane A, the bottom end of the flashboard does not contact the bottom surface B of the inner cavity of the valve body and the flashboard is completely in a full-floating state. Therefore, when acting on one side of the flashboard, a medium acting force drives the other side of the flashboard to be completely jointed with the sealing surface of a valve seat, thereby increasing the sealability of the valve. Simultaneously, as the flashboard is in a full-floating state, the opening torque is small.
Description
Technical field
The utility model relates to a kind of plate valve, particularly a kind of full floating plate valve.
Background technique
At present, plate valve all adopts down position structure, and also, when valve closing, flashboard contacts with the valve body bottom plane.In the using process, need behind the valve closing handwheel revolution 1/4th circles so that flashboard leaves the bottom plane, are suspended in the valve pocket, be in quick condition.
In the above-mentioned prior art, it is mainly not enough: the one, if flashboard forgets revolution 1/4th circles when cutting out, then the flashboard end is in quick condition, thereby reduced the sealability of valve, and it is big to open moment simultaneously; The 2nd, if driving mode is not the handwheel transmission, but alternate manners such as electronic or gear transmission then turn round 1/4th circles and are not easy control.
Summary of the invention
Technical barrier to be solved in the utility model is, it is wayward or forget the deficiency of revolution to overcome flashboard revolution 1/4th circles in the prior art, but a kind of full floating plate valve of automatic spacing is provided.
The technical solution of the utility model is,
Be provided with valve body, be provided with valve rod and flashboard in the valve body, flashboard snaps onto the downside of valve rod, and valve seat is housed on the valve body, and it is characterized in that: valve rod is provided with limiting stopper, and the side opening wall of body cavity is provided with the spacing plane that can make the limiting stopper axial limiting.
Limiting stopper by scyewed joint on valve rod.
The utility model has the advantages that when valve closing, the limiting stopper on the valve rod contacts with spacing plane on the valve body, flashboard is suspended on the spacing plane, and the bottom of flashboard do not contact with the body cavity bottom surface, and flashboard is in the full floating state.Thereby when the medium active force acted on a side of flashboard, the sealing surface that promotes flashboard another side and valve seat was fitted fully, has increased the sealability of valve.Simultaneously, because flashboard is in the full floating state, its unlatching moment is little.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Number in the figure: 1-valve rod, 2-limiting stopper, 3-valve body, 4-valve seat, 5-flashboard, the spacing plane of A-valve body, B-body cavity bottom surface.
Embodiment
The utility model comprises valve rod 1, limiting stopper 2, valve body 3, valve seat 4, flashboard 5.
Valve rod 1 and flashboard 5 are located in the valve body 3, and flashboard 5 is located at the downside of valve rod 1, and link by T shape button, and valve seat 4 is contained on the valve body 3.Valve rod 1 is provided with a limiting stopper 2, is processed with the spacing plane A that can make the limiting stopper axial limiting on the side opening wall of valve body 3 inner chambers, limiting stopper 2 by scyewed joint on valve rod 1.Limiting stopper 2 and flashboard 5 can move up and down with valve rod 1, and valve is carried out opening and closing.
When valve closing, valve rod 1 drive limiting stopper 2 and flashboard 5 are descending, limiting stopper 2 on the valve rod 1 contacts with spacing plane A on the valve body 3, flashboard 5 stops descending, flashboard 5 is suspended on the spacing plane A, and this moment, the bottom of flashboard 5 did not contact with body cavity bottom surface B, left certain clearance, so flashboard 5 is in the full floating state in valve pocket.When the medium active force acts on the side of flashboard 5, promote the another side of flashboard 5 and the sealing surface of valve seat 4 and fit fully, thereby increased the sealability of valve.
Because the opening and closing of flashboard 5 are in the full floating state, thereby unlatching moment is little.
