Abstract
The utility model relates to a kind of valve rod fixed structure, comprises valve body, valve seat, valve rod, valve gap and flashboard; Described valve seat is arranged on body base, and valve gap is arranged on body top; Described valve rod is arranged in valve body, and valve gap is stretched out in one end, the other end bottom welding limited location block; Described flashboard is welded on limiting stopper other end; Wear-resistant pad is provided with between described limiting stopper and valve body; Described valve rod coordinates the inner to be provided with valve gap to hold out against spring; The described spring one end that holds out against is fixed on valve inner, and the other end is connected with jacking block; Seal ring holds out against in stem surface by described jacking block, plays fixation; The utility model scheme avoids the conflict of power between valve rod and flashboard, ensure that the normal use of valve, holds out against spring and play stabilization to valve rod, ensure that overall stability, decreases the damage of misoperation to valve seat and flashboard.
Description
Technical field
The utility model relates to a kind of valve rod fixed structure, belongs to plate valve technical field.
Background technique
Plate valve flashboard is pushed to outlet valve valve seat realization sealing by the pressure of valve inlet place medium, so firmly fasten plate valve not only can not play good seal action, on the contrary valve seat and flashboard are damaged to some extent, impact sealing, some producer indicates in product descritption, and this valve closes on earth refunds 1/4 or 1/2 again, but misoperation phenomenon still happens occasionally in practical operation, there is the phenomenon of valve rod shakiness simultaneously, be unfavorable for the running of gate valve.
Model utility content
The utility model object provides a kind of extend valve working life and the valve rod fixed structure of good stability to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of valve rod fixed structure, comprises valve body, valve seat, valve rod, valve gap and flashboard; Described valve seat is arranged on body base, and valve gap is arranged on body top; Described valve rod is arranged in valve body, and valve gap is stretched out in one end, the other end bottom welding limited location block; Described flashboard is welded on limiting stopper other end; Wear-resistant pad is provided with between described limiting stopper and valve body; Described valve rod coordinates the inner to be provided with valve gap to hold out against spring; The described spring one end that holds out against is fixed on valve inner, and the other end is connected with jacking block; Seal ring holds out against in stem surface by described jacking block, plays fixation.
Preferably, described flashboard is provided with lubrication groove with the valve seat place of matching.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of valve rod fixed structure of the utility model scheme, by valve rod is arranged in valve body, valve gap is stretched out in one end, the other end bottom welding limited location block, valve rod coordinates the inner to be provided with valve gap to hold out against spring, hold out against spring one end and be fixed on valve inner, the other end is connected with jacking block, seal ring holds out against in stem surface by jacking block, play fixation, when gate valve operates, limiting stopper top is on valve body, flashboard cannot be continued descending, avoid the conflict of power between valve rod and flashboard, ensure that the normal use of valve, hold out against spring and stabilization is played to valve rod, ensure that overall stability, decrease the damage of misoperation to valve seat and flashboard.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of a kind of valve rod fixed structure of the present utility model;
Wherein: 1, valve body; 2, valve seat; 3, valve rod; 4, valve gap; 5, flashboard; 6, limiting stopper; 7, wear-resistant pad; 8, spring is held out against; 9, jacking block; 10, seal ring; 11, lubrication groove.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of valve rod fixed structure described in the utility model, comprises valve body 1, valve seat 2, valve rod 3, valve gap 4 and flashboard 5; Described valve seat 2 is arranged on bottom valve body 1, and valve gap 4 is arranged on valve body 1 top; Described valve rod 3 is arranged in valve body 1, and valve gap 4 is stretched out in one end, the other end bottom welding limited location block 6; Described flashboard 5 is welded on limiting stopper 6 other end; Wear-resistant pad 7 is provided with between described limiting stopper 6 and valve body 1; Described valve rod 3 coordinates the inner to be provided with valve gap 4 to hold out against spring 8; Described spring 8 one end that holds out against is fixed on valve body 1 inside, and the other end is connected with jacking block 9; Seal ring 10 holds out against on valve rod 3 surface by described jacking block 9, plays fixation; Described flashboard 5 is provided with lubrication groove 11 with valve seat 2 place of matching.
A kind of valve rod fixed structure of the utility model scheme, by valve rod 3 is arranged in valve body 1, valve gap 4 is stretched out in one end, the other end bottom welding limited location block 6, valve rod 3 coordinates the inner to be provided with valve gap 4 to hold out against spring 8, hold out against spring 8 one end and be fixed on valve body 1 inside, the other end is connected with jacking block 9, seal ring 10 holds out against on valve rod 3 surface by jacking block 9, play fixation, when gate valve operates, limiting stopper 6 pushes up on valve body 1, flashboard 5 cannot be continued descending, avoid the conflict of power between valve rod 3 and flashboard 5, ensure that the normal use of valve, hold out against spring 8 pairs of valve rods 3 and play stabilization, ensure that overall stability, decrease the damage of misoperation to valve seat 2 and flashboard 5.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
