Abstract
The utility model relates to the field of valves, in particular to a novel stop valve preventing a valve rod against deformation. The novel stop valve is characterized by comprising a valve handle, a valve cap, a hole, the 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 stop valve preventing the valve rod against the deformation, the stroke socket is arranged on the valve rod, the stroke socket protects the valve rod, the valve rod is prevented from shocking, deforming and breaking, 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 valve rod distortion fracture valve that prevents.
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 valve stem crack 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 valve rod distortion fracture valve that prevents; described a kind of novel valve rod distortion fracture no-leakage valve that prevents; 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 valve rod distortion fracture valve that prevents; be provided with stroke socket 9 at valve rod 4; its stroke socket 9 is protection valve rods 4, prevents valve rod 4 concussion distortion fractures.
The beneficial effects of the utility model: can realize the rapidly opened and closed of valve, prevent valve rod 4 concussion distortion fractures, 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 valve rod distortion fracture valve that prevents is provided with stroke socket 9 at valve rod 4, and its stroke socket 9 is protection valve rods 4, prevents valve rod 4 concussion distortion fractures.
Claims (1)
1. the novel valve rod that prevents is out of shape the fracture valve, it is characterized in that, comprise: valve handle, valve gap, hole, valve rod, valve rod bolt, spring, flap, seal, stroke socket, seal groove, anti-mouth, the sealing of anti-bolt, the valve body of pushing up of flap, described a kind of novel valve rod distortion fracture valve that prevents is provided with the stroke socket at valve rod.
