Abstract
The utility model relates to the field of valves, in particular to a novel deformation-prevention stop valve. The novel deformation-prevention stop valve is characterized by comprising a valve handle, a valve cap, a hole, a valve rod, a valve rod bolt, a spring, a valve clack, a seal body, a stroke socket, a sealing groove, a valve clack reverse abutting opening, a reverse bolt seal and a valve body. According to the novel deformation-prevention stop valve, the reverse bolt seal is arranged on the valve body, the reverse bolt abuts against the valve clack, deformation and leakage of the valve clack are prevented, rapid opening and closing of the valve are achieved, and time is earned for dangerous source cutting off under an emergency condition.
Description
Technical field
The utility model relates to valve field, especially a kind of novel cut-off valve that prevents from being out of shape.
Background technique
Existing gas valve technical field, closing of valve all is to rely on the rotation of valve rod to promote flap to move up and down, realize closing of valve, but threaded stem rotational motion to linear motion speed is slow, especially state of emergency lower valve is from the opening state to the closed state, actuation time is long, causes easily distortion and medium seepage, can not satisfy the requirement of fast shut-off source of the gas.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of novel cut-off valve that prevents from being out of shape, described a kind of novel cut-off valve that prevents from being out of shape, it is characterized in that, comprise: valve handle 1, valve gap 2, hole 3, valve rod 4, valve rod bolt 5, spring 6, flap 7, seal 8, stroke socket 9, seal groove 10, anti-mouth 11, anti-bolt sealing 12, the valve body 13 of pushing up of flap, described a kind of novel cut-off valve that prevents from being out of shape, be provided with anti-bolt sealing 12 at valve body 13, flap 7 is withstood in its anti-bolt sealing 12, prevents flap distortion seepage.
The beneficial effects of the utility model: can realize the rapidly opened and closed of valve, prevent flap distortion seepage, win the time for cutting off dangerous matter sources under the state of emergency.
Description of drawings
Fig. 1 is the utility model schematic representation;
Wherein: valve handle 1, valve gap 2, hole 3, valve rod 4, valve rod bolt 5, spring 6, flap 7, seal 8, stroke socket 9, seal groove 10, anti-mouth 11, anti-bolt sealing 12, the valve body 13 of pushing up of flap.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
Such as Fig. 1, described a kind of novel cut-off valve that prevents from being out of shape is provided with anti-bolt sealing 12 at valve body 13, and flap 7 is withstood in its anti-bolt sealing 12, prevents flap distortion seepage.
