Description
Technical field
The present invention relates to a kind of safety valve more particularly to a kind of heat temperature resistant safe valves.
Background technique
Safety valve is a kind of safeguard protection valve, its opening and closing element is in normally off under by external force, when equipment or
Pressure medium in pipeline increases, and automatically turns on when more than specified value, by preventing pipeline or equipment to system outlet medium
Interior pressure medium is more than specified value, has run important protective effect to personal safety and equipment.Safety valve in the prior art
Technique is more coarse, and spool, which is assemblied in valve body to move up and down, card resistance phenomenon occurs, and leakproofness is poor between spool and valve seat, not
Safety valve is with regard to gas leakage when reaching cracking pressure, and there are security risks.
Summary of the invention
The present invention provide in order to solve problem above a kind of structure is simple, safety is good, leakproofness is high, it is stable,
Long service life is quick on the draw, the heat temperature resistant safe valve of good heat dissipation effect.
The technical scheme is that the safety valve generally full-closed structure, the safety valve include bonnet,
Valve deck, valve rod, flap, valve seat and valve body, the bonnet are arranged at the top of safety valve, and the bonnet lower part and valve deck are removable
Connection is unloaded, interconnecting piece is equipped with sealing ring, and the valve rod is vertically arranged in safety valve, it is provided with spring on the valve rod,
The flap is arranged below valve rod, and the flap lower part connecting valve seat, the valve body is connected on valve seat, described
Valve body and valve seat are connected through a screw thread.
The configuration of the present invention is simple, safety is good, leakproofness is high, stable, long service life, is quick on the draw, heat dissipation effect
Fruit is good.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is valve body in figure, and 2 be valve seat, and 3 be regulating valve, and 4 be flap, and 5 be guide sleeve, and 6 be cooling fin, and 7 be valve deck, and 8 are
Spring.
Specific embodiment
A kind of heat temperature resistant safe valve, the safety valve include valve body 1, valve seat 2, regulating valve 3, flap 4, guide sleeve 5, valve
Bar, cooling fin 6, valve deck 7 and spring 8, in safety valve bottom, the valve seat 2 is arranged in valve body 1 for the setting of valve body 1,
The regulating valve 3 is arranged on valve seat 2, and the flap 4 is arranged above valve seat 2, and the valve rod is vertically arranged in valve
In lid 7, the setting of flap 4 is in stem lower portion, and the guide sleeve 5 is arranged on flap 4, and the valve deck 7 is connected to
1 top of valve body is connected with handle on the valve deck 7, and the spring 8 is socketed on valve rod, and the valve deck 7, which is equipped with, to be seen
It examines window viewing spring 8 to move, the cooling fin 6 is arranged in the outer surrounding of valve body 1.
Above embodiments are only to illustrate the invention and not limit technical solution described in the invention；Cause
This, is although this specification has been carried out detailed description to the invention referring to above-mentioned each embodiment, this field
It is to be appreciated by one skilled in the art that still can modify to the invention or equivalent replacement；And all do not depart from this
The technical solution and its improvement of the spirit and scope of innovation and creation, should all cover the scope of the claims in the invention
In.
