Abstract
The invention discloses a valve rod limiting structure for a flat gate valve. The valve rod limiting structure comprises a valve rod and a gate plate, wherein the valve rod is arranged in a valve body; the valve body and a valve seat are fixed together; a limiting block is welded at the bottom of the valve rod; and the gate plate is welded on the other end face of the limiting block. According to the scheme of the invention, the limiting block is welded at the bottom of the valve rod, the gate plate is welded on the other end face of the limiting block, and the limiting block is pressed against the valve body when the valve is closed in place so as to prevent the valve plate from moving downwards continually, so that the valve rod is prevented from being contacted with the gate plate, normal use of the valve is ensured, and damages to the valve seat and the gate plate caused by error operation are reduced.
Description
Technical field
The present invention relates to a kind of plate valve valve stem spacing structure, belong to the plate valve technical field.
Background technique
Plate valve is to push flashboard to the outlet valve valve seat by the pressure of valve inlet place medium to realize sealing, not only can not play good seal action so firmly fasten plate valve, on the contrary valve seat and flashboard are damaged to some extent, the impact sealing, some producer is poisoning dated at product descritption, this valve refunds 1/4 or 1/2 after closing on earth again, but the misoperation phenomenon still happens occasionally in practical operation.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of valve plate valve valve stem spacing structure in working life that extends.
Technical solution of the present invention is achieved in that a kind of plate valve valve stem spacing structure, comprises valve rod, flashboard, and valve rod is arranged in valve body, and valve body and valve seat are fixed, and described stem bottom is welded with limiting stopper; Described flashboard is welded on the limiting stopper other end.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of plate valve valve stem spacing structure of the present invention, by being welded on the limiting stopper other end at stem bottom welded limiting piece with by flashboard, when the valve pass puts in place, limiting stopper pushes up on valve body, flashboard can't be continued descending, avoid the conflict of power between valve rod and flashboard, guaranteed the normal use of valve, also reduced the damage of misoperation to valve seat and flashboard.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The schematic diagram that accompanying drawing 1 is a kind of plate valve valve stem spacing structure of the present invention;
Wherein: 1, valve rod; 2, flashboard; 3, valve body; 4, valve seat; 5, limiting stopper.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is a kind of plate valve valve stem spacing structure of the present invention, comprises valve rod 1, flashboard 2, and valve rod 1 is arranged in valve body 3, and valve body 3 is fixing with valve seat 4, described valve rod 1 bottom welding limited location piece 5; Described flashboard 2 is welded on limiting stopper 5 other ends.
By at valve rod 1 bottom welding limiting stopper 5 with flashboard 2 is welded on limiting stopper 5 other ends, when the valve pass puts in place, limiting stopper 5 tops are to valve body 3, flashboard 2 can't be continued descending, avoided the conflict of power between valve rod 1 and flashboard 2, guarantee the normal use of valve, also reduced the damage of misoperation to valve seat 4 and flashboard 2.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (1)
