Abstract
The utility model relates to a spring fall lift closed safety valve with a closed radiator, which mainly solves the problem of poor heat dissipation performance of the exiting safety valve. The radiator is arranged between a valve cover and a valve body; the radiator is adhered to a guide sleeve, sleeved on the periphery of a valve rod and connected with the interior of a valve body through a bolt; and a metal rustproof layer is coated on the surface of the radiator. The spring fall lift closed safety valve with the radiator has good heat dissipation performance, guarantees the stability of spring performance, can not hinder the overall performance of the spring, ensures that the operation performance is accurate and reliable and the operating temperature inside the valve is increased to smaller than or equal to 450 DEG C from originally smaller than or equal to 300 DEG C, improves the operating efficiency, and also has the advantages of wide application range, economical efficiency and practicability.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to band sealing radiator spring Fall lift safety valve.
Background technique
Safety valve is a kind of safety protection valve; its open-shut device is subjected to be in normally off under External Force Acting; pressure medium in equipment or pipeline raises, and automatically opens while surpassing specified value, prevents that by outside system, discharging medium in pipeline or equipment, pressure medium surpasses specified value.Safety valve belongs to the self-acting valve class, is mainly used on boiler, pressurized container and pipeline, and pilot pressure is no more than specified value, and personal safety and equipment have been moved to important protective action.Safety valve in the prior art, all exist some defects, such as thermal characteristics is bad.Can not well solve in time the problem that spring is heated and can't dispels the heat.And the operating temperature in valve can only be at≤300 ℃, the temperature of working environment is too low, long term high temperature can make the unstable properties of spring, the phenomenon of expanding with heat and contract with cold, can hinder the overall performance of valve like this, in use, can not reach precisely reliable, reduce the working efficiency of valve, Applicable scope is too little, economical and practical not.
Summary of the invention
In order to overcome the deficiency of background technique, the utility model provides band sealing radiator spring Fall lift safety valve, mainly solved the poor problem of existing safety valve heat dispersion, this safety valve perfect heat-dissipating, guaranteed the stable of spring performance, can not hinder the overall performance of valve, make service behaviour precisely reliable, improved the operating temperature of valve, improved working efficiency, and has advantage applied widely, economical and practical.
The technological scheme that the utility model adopts is: band sealing radiator spring Fall lift safety valve, comprise valve body, valve gap, in valve body, be provided with valve seat, valve seat has been accessibly connected flap towards an end of valve gap, be connected Disc holder and Disc holder of flap is socketed on outside flap, Disc holder is arranged with guide sleeve outward, guide sleeve is fixedly connected with valve body, in valve gap, be provided with spring seat, spring seat is provided with spring, spring housing is located on valve rod, flap in valve rod and valve body is connected, between described valve gap and valve body, be provided with radiator, described radiator is fixedly connected between valve body and valve gap, described radiator top layer scribbles the metal rust preventing layer.
By adopting technique scheme, setting up of radiator, improved the heat dispersion of safety valve, and the radiator top layer scribbles the metal rust preventing layer, be not easy to be corroded, not fragile, guaranteed the stable of spring performance, can not hinder the overall performance of valve, make service behaviour precisely reliable, improved the using scope of valve working temperature, improved working efficiency, and have applied widely, economical and practical.
The utility model further is set to: described sealing radiator spring Fall lift safety valve, described radiator becomes I shape along the axial cross section of valve rod, and radiator is provided with the through hole worn for valve rod.
By adopting above-mentioned technological scheme, can well radiator be fixed between valve body and valve gap, improve rationality and the reliability of structure.
The utility model further is set to: the sealing surface of described valve seat is that Hardmetal materials is made.
By adopting above-mentioned technological scheme, the high hardness of this material and wear resistance are very good, the life cycle that has extended valve seat.
The utility model further is set to: described flap is integrally formed with by stainless iron material high frequency hardening and forms valve clack sealing surface.
By adopting above-mentioned technological scheme, economical and practical.
The beneficial effects of the utility model are: owing to taking technique scheme, improved the heat dispersion of safety valve, and radiator is not easy to be corroded, not fragile, guaranteed the stable of spring performance, can not hinder the overall performance of valve, make service behaviour precisely reliable, by the operating temperature in valve by original≤300 ℃ bring up to≤450 ℃, improved working efficiency, and has advantage applied widely, economical and practical.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model band sealing radiator spring Fall lift safety valve.
1-valve body in figure, 2-valve gap, 3-valve seat, 4-flap, 5-Disc holder, 6-guide sleeve, 7-spring seat, 8-spring, 9-valve rod, 10-radiator.
Embodiment
Below in conjunction with accompanying drawing, the utility model band sealing radiator spring Fall lift safety valve embodiment is described further:
As shown in Figure 1, band sealing radiator spring Fall lift safety valve, comprise valve body 1, valve gap 2, in valve body 1, be provided with valve seat 3, valve seat 3 has been accessibly connected flap 4 towards an end of valve gap 2, be connected Disc holder 5 and Disc holder of flap 4 is socketed on outside flap 4, Disc holder 5 is arranged with guide sleeve 6, guide sleeve 6 is fixedly connected with valve body 1, in valve gap 2, be provided with spring seat 7, spring seat 7 is provided with spring 8, spring 8 is sheathed on valve rod 9, valve rod 9 is connected with the flap 4 in valve body 1, between described valve gap 2 and valve body 1, be provided with radiator 10, described radiator 10 is fixedly connected between valve body 1 and valve gap 2, described radiator 10 top layers scribble the metal rust preventing layer.After the high pressure produced after the pressure anomaly of pressurized container, can overcome spring 8 pressure of safety valve, blocking device will be backed down, and has formed a pressure release passage, high pressure could be released like this.Medium can produce a large amount of heat energy in pressure release, the safety valve of radiator 10 is housed, can well the dissipation of heat in valve be gone out, by the operating temperature in valve by original≤300 ℃ bring up to≤450 ℃, improved the efficiency of work, and ensured the overall performance of valve, make valve have accuracy highly, and radiator 10 skins have scribbled resin layer, radiator 10 is difficult for being corroded, be not easy to damage, such design has advantage applied widely, economical and practical.
