Abstract
The utility model relates to an anti-jumping structure of a stay rod type closing device of a parallel type double gate plate. A left and a right gate plates of an anti-jumping mechanism are mutually buckled and connected with the positions at one side of a valve rod, and the upper parts of the left and the right gate plates are provided with block pieces. The utility model effectively solves the problems that when the gate valve is opened or closed, the left and the right gate plates can not vertically move up and down to be clamped, and even, the sealing surfaces of the gate plates and a gate seat are damaged because of the upward and the downward movement of a stay rod. The gate valve is easily and safely opened or closed.
Description
Technical field
The utility model relates to the valve closing device, particularly the anti-play structure of double disk parallel gate valve Jackstay type shutoff device.
Background technique
Existing double disk parallel gate valve Jackstay type shutoff device is for preventing left side flashboard and right flashboard generation screens phenomenon when opening or closing gate valve, employing is provided with anti-play assembly parts between left flashboard and right flashboard, promptly on left flashboard and right flashboard inboard, be provided with pin shaft hole respectively, a bearing pin is installed in two pin shaft holes versatilely.Owing to adopted above-mentioned anti-play assembly parts, solved to a certain extent that left side flashboard and right flashboard easily produce the problem of screens when opening or closing gate valve.Owing between the left flashboard of anti-play assembly parts and pin-and-hole on the right flashboard and bearing pin certain interval is arranged, and under valve upside-down mounting state with the valve complete opening after when closing again, flashboard still might break away from mutually and produce the screens phenomenon.Solve the upper and lower screens problem when mobile of left flashboard and right flashboard fully so should anti-play assembly parts fail.
Summary of the invention
The purpose of this utility model provides a kind of anti-play structure of double disk parallel gate valve Jackstay type shutoff device, and this structure can make left flashboard and right flashboard open or close Shi Buhui generation screens phenomenon at gate valve.
Technical solution of the present utility model is that the left flashboard of the anti-play structure of double disk parallel gate valve Jackstay type shutoff device is fastened and connected mutually with the position of a side that is connected with valve rod of right flashboard, is provided with block piece on the top of left flashboard, right flashboard.
The position that is fastened and connected mutually of above-described left flashboard and right flashboard can be along circumferentially being respectively equipped with projection, on the projection of left flashboard or right flashboard, be provided with concave ring groove, be provided with convex platform on the projection of right flashboard or left flashboard, convex platform embeds forms the linkage structure that fastens mutually in the concave ring groove.
Block piece of the present utility model can be the cotter pin of passing valve rod, and the two ends of cotter pin place the top of left and right flashboard respectively.
Block piece of the present utility model can be the block that is fixed on the Stem Mut, and block places the top of left and right flashboard.
Principle of the present utility model is when double disk parallel gate valve Jackstay type shutoff device opens or closes gate valve, valve rod by with drive that left and right flashboard is upper and lower to be moved being connected of left and right strut.Because left and right flashboard is respectively equipped with the concave ring groove and the convex platform of mutual fastening on the side of strut, make valve rod when driving left and right flashboard action, do whole moving.And the block piece of going up setting at the valve rod (under the situation of Outside screw stem rising through handwheel type gate valve) or the Stem Mut (under the situation of inside screw non-rising stem type gate valve) of relevant position, flashboard top makes valve can stop flashboard to move down under the upside-down mounting state, thereby prevent gate valve under any circumstance, valve rod can not produce swing and the phenomenon of generation screens when driving ram movement.
The utility model has the advantages that left flashboard and right flashboard were all done as a whole moving when gate valve opened or closed under the situation of any mounting point, avoided the generation of screens phenomenon, and made gate valve free and relaxed when opening or closing.
