Description
Technical field
The utility model relates to gate valve, particularly a kind of high-pressure gate valve of easy breakdown.
Background technique
Conventional valves is taper single valve plate and double valve plates no matter, is all subject to the restriction that top is pressed and expanded with heat and contract with cold, and breakdown is difficult.Therefore conventional valves is provided with balance tube and equilibrium valve after and before the valve, bring operational loaded down with trivial detailsly, and breakdown is also difficult.
In view of this, the high-pressure gate valve of seeking a kind of easy breakdown becomes pursuing a goal of these those skilled in the art.
Summary of the invention
Task of the present utility model is to provide a kind of easy open high-pressure gate valve, it has solved the existing problem of above-mentioned prior art, this valve is double-flashboard, when breakdown main gate-board, it is state of rest, not pressed by top affects, solved the drawback that the fluid pressure official post valve of conventional high-tension gate valve when breakdown cannot breakdown and the impact of expanding with heat and contract with cold, the balance tube after and before the valve and the equilibrium valve that have saved conventional valves bring operational loaded down with trivial details; This valve operation is simple, easily breakdown.
Technical solution of the present utility model is as follows:
An easy open high-pressure gate valve, it comprises valve body, valve rod and valve seat, it also comprises valve gap, gland, valve disc, main gate-board, auxiliary gate-board and valve seat sealing device;
In the middle of described valve gap, be provided with bump with holes upwards, valve rod upwards passes valve gap bump from valve inner, and gland with holes is arranged on valve gap bump mouth place, and is tightened up by fastening piece;
Described valve disc is arranged on valve rod top, and is tightened up by nut;
Described main gate-board is arranged on valve rod bottom, and main gate-board and auxiliary gate-board are respectively equipped with fluid passage, and main gate-board is connected by latch or bolt with auxiliary gate-board, connects auxiliary gate-board fluid passage during main gate-board breakdown;
Described valve seat is provided with valve seat sealing device.
Between the inwall of described valve gap bump and valve rod, valve rod sealing device is housed.
A kind of easy open high-pressure gate valve of the present utility model has double-flashboard, when breakdown main gate-board, is state of rest, and not pressed by top affects, and while joining auxiliary gate-board, opens fluid passage, and hydrodynamic pressure after and before the valve reaches autobalance state; Solved the drawback that the fluid pressure official post valve of conventional high-tension gate valve when breakdown cannot breakdown and the impact of expanding with heat and contract with cold, saved the balance tube after and before the valve of conventional valves and equilibrium valve and brought operational loaded down with trivial detailsly, and breakdown is difficult.
Easy open high-pressure gate valve of the present utility model is simple to operate, and easily breakdown, reliably convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of easy open high-pressure gate valve of the present utility model.
Reference character:
1 is nut, and 2 is valve rod, and 3 is valve disc, and 7 is fastening piece, and 9 is gland, and 11 is valve rod sealing device, and 12 is bolt, and 13 is pad, and 14 is valve body, and 15 is valve seat sealing device, and 16 is latch, and 17 is main gate-board, and 18 is auxiliary gate-board, and 19 is valve gap.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Referring to Fig. 1, the utility model provides a kind of easy open high-pressure gate valve, and it is mainly comprised of valve body 14, valve rod 2, valve gap 19, gland 9, valve disc 3, main gate-board 17, auxiliary gate-board 18, valve seat and valve seat sealing device 15.
In the middle of valve gap 19, be provided with bump with holes upwards, valve rod 2 upwards passes valve gap 19 bumps from valve body 14 inside, and gland 9 with holes is arranged on valve gap 19 bump mouth places, and is tightened up by fastening piece 7.
Valve disc 3 is arranged on valve rod 2 tops, and is tightened up by nut 1.
Main gate-board 17 is arranged on valve rod 2 bottoms, main gate-board 17 is provided with fluid passage, main gate-board 17 is connected by latch 16 or bolt with auxiliary gate-board 18, auxiliary gate-board 18 is also provided with fluid passage, during main gate-board 17 breakdown, connect auxiliary gate-board 18 fluid passages, hydrodynamic pressure after and before the valve just reaches autobalance state.
On valve seat, be provided with valve seat sealing device 15.Between the inwall of valve gap 19 bumps and valve rod 2, valve rod sealing device 11 has been installed.
During easy open high-pressure gate valve work of the present utility model, rotate valve disc 3, valve rod 2 pulls main gate-board 17, during main gate-board 17 breakdown, connect auxiliary gate-board 18 fluid passages, by releasing, reach pressure balance, and do not need by balance tube and equilibrium valve after and before the valve, automatically solve pressure balance problem after and before the valve.
In sum, easy open high-pressure gate valve of the present utility model is double-flashboard, when breakdown main gate-board, is state of rest, and not pressed by top affects, and while joining auxiliary gate-board, opens fluid passage, and hydrodynamic pressure after and before the valve reaches autobalance state.Easy open high-pressure gate valve of the present utility model is simple to operate, and easily breakdown, reliably convenient.
Certainly, those skilled in the art in the art will be appreciated that, above-described embodiment is only for the utility model is described, and not with opposing restriction of the present utility model, as long as within the scope of connotation of the present utility model, the variation of above-described embodiment, modification etc. all will be dropped in the scope of the utility model claim.
