Abstract
The utility model discloses an explosion -proof valve body of durable type belongs to valve technical field, and it includes valve body, the valve plate of closing cap in the valve body export, still includes roof, regulating plate, adjusting screw and 2 piece at least guide posts, the guide post is connected perpendicularly between valve body and roof, and valve plate and regulating plate sliding connection are equipped with the spring between valve plate and the regulating plate on the guide post, and the spring is in compression state all the time, sticiss the valve plate on the valve body, the roof center has a screw hole, adjusting screw and this screw hole threaded connection to pass the rotatable butt of this screw hole on the regulating plate. This kind of explosion -proof valve body of durable type does not need the rupture disk, can use repeatedly, and is convenient durable, can avoid the secondary explosion moreover, and critical pressure that can also adjustment device satisfies multiple demand.
Description
Technical field
This utility model relates to a kind of explosion-proof valve body, belongs to valve technology field.
Background technology
Explosion-proof valve is a kind of pressure relief device compressing explosive equipment, is widely used in the industry departments such as building materials, metallurgy, chemical industry, electric power, its simple in construction, mainly includes steel welding valve body and rupture disk.When internal system excessive pressure supercharging and when reaching rupture disk limiting pressure, rupture disk moment breaks, and plays the effect of releasing pressure automatically, the blast of prevention system.This explosion-proof valve has the disadvantage in that 1, rupture disk is disposable products, is required for changing rupture disk after each pressure release, is not durable also inconvenient；2, need the critical pressure of change equipment in some cases, and the burst pressure of rupture disk is fixed, it is impossible to selectively set；3, after rupture disk breaks, valve port is open type, can cause outside air access arrangement, produces subsequent explosion.
Utility model content
Technical problem to be solved in the utility model is in that to overcome the problems referred to above, and provides a kind of explosion-proof valve body of durable type, can not only avoid subsequent explosion, and can Reusability, moreover it is possible to regulate critical pressure.
The technical solution of the utility model is:
A kind of explosion-proof valve body of durable type, including valve body, the valve plate being covered on valve outlet, it is characterised in that: also include top board, adjustable plate, adjusting screw rod and at least 2 leads；Described lead is vertically connected between valve body and top board, and valve plate and adjustable plate are slidably connected on lead, and equipped with spring between valve plate and adjustable plate, spring is in compressive state all the time, is pressed on valve body by valve plate；Top board center has a screwed hole, and described adjusting screw rod is threadeded with this screwed hole, and is connected on adjustable plate through this screwed hole is rotating.
As what optimize, the abutting place of valve plate described in the utility model and valve body is provided with sealing ring, and this sealing ring is fixed on valve body.
As what optimize, the center of adjustable plate described in the utility model upwardly extends formation one hollow cylinder, and adjusting screw rod is connected in hollow cylinder.
As what optimize, the quantity of lead described in the utility model is 3.
The beneficial effects of the utility model are: the structure 1, utilizing spring to be pressed on valve body by valve plate, instead of rupture disk, when pressure is excessive in equipment, valve plate is flicked pressure release, resets rapidly afterwards, it is prevented that air enters, can not only Reusability, facilitate durable, and be avoided that subsequent explosion；2, the structure such as adjustable plate, adjusting screw rod is set, changes the distance between adjustable plate and valve plate by rotating adjusting screw rod, namely change the decrement of spring, the decrement of spring is more big, air pressure required for then flicking valve plate is more big, with this critical pressure regulating equipment, meets multiple demand.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
In conjunction with drawings and Examples, this utility model is further described:
As it is shown in figure 1, the explosion-proof valve body of the durable type of the present embodiment, including valve body 10, being covered in the valve plate 20 that valve body 10 exports, also include top board 30, adjustable plate 40, adjusting screw rod 50 and at least 2 leads 60, in the present embodiment, the quantity of lead 60 is 3.
Lead 60 is vertically connected between valve body 10 and top board 30, and valve plate 20 and adjustable plate 40 are slidably connected on lead 60, and equipped with spring 70 between valve plate 20 and adjustable plate 40, spring 70 is equal with lead 60 quantity, is sheathed on each lead 60.Spring 70 is in compressive state all the time, is pressed on valve body 10 by valve plate 20, and the abutting place of valve plate 20 and valve body 10 is provided with sealing ring 80, thus the sealing ensured between valve plate 20 and valve body 10, this sealing ring 80 is fixed on valve body 10.When in equipment, pressure is excessive, valve plate 20 is flicked pressure release by the gas in equipment, and after pressure release, valve plate 20 resets rapidly under the effect of spring 70, it is prevented that air enters, it is to avoid subsequent explosion.
Top board 30 center has a screwed hole, and adjusting screw rod 50 is threadeded with this screwed hole, and is connected on adjustable plate 40 through this screwed hole is rotating.The center of adjustable plate 40 upwardly extend formation one hollow cylinder 41, adjusting screw rod 50 is connected in this hollow cylinder 41, hollow cylinder 41 the connection reliability that can improve between adjusting screw rod 50 and adjustable plate 40 is set.When needing the critical pressure of adjustment equipment, rotate adjusting screw rod 50 and change the distance between adjustable plate 40 and valve plate 20, then change the decrement of spring 70 simultaneously, and the decrement of spring 70 is more big, air pressure required for flicking valve plate 20 is more big, therefore rotate adjusting screw rod 50 and just can realize the adjustment of critical pressure, simple and convenient, multiple demand can be met.
It is understood that for the person of ordinary skill of the art, it is possible to make other various corresponding changes and deformation according to technology of the present utility model design, and all these change and deformation all should belong to this utility model scope of the claims.
