Abstract
The utility model discloses a special explosion-proof valve for a heating stove. The special explosion-proof valve comprises an explosion-proof valve seat, a rupture disk and a compressing screw ring cover, wherein the rupture disk is placed between the explosion-proof valve set and the compressing screw ring cover and takes the shape of a stepped inwardly concave cylinder; the explosion-proof valve seat and the compressing screw ring cover are in threaded connection; the outer side of the compressing screw ring cover is nut-shaped, and the inner side of the compressing screw ring cover is stepped and hollow; the interior of the explosion-proof valve seat is isometric and hollow, external threads connected with a pipeline are formed on the upper outer side of the explosion-proof valve seat, a convex ring is arranged in the middle of the explosion-proof valve seat, and external threads connected with the compressing screw ring cover are formed at the lower part of the explosion-proof valve seat. The special explosion-proof valve has the benefits that the processing and manufacturing are convenient and fast and are at least two times quicker than the conventional processing and manufacturing on the market; the assembly and the disassembly are quick, the rupture disk has low probability of damage, and the product cost can be lowered when a new manufacturing material is chosen.
Description
Technical field
The utility model relates to safety valve technical field, particularly relates to a kind of air heating stove special anti-explosion valve.
Background technique
Explosion-proof valve is a kind of safety installations that reduces closed container.Particularly, in air heating stove, when pressure is excessive, first explosion-proof valve can explode, and to reduce the pressure in air heating stove, avoids the generation of accident.But, after the burst disk breakage in existing explosion-proof valve, need to dismantle explosion-proof valve, after dismounting, changing separately burst disk, Renewal process is complicated, changes efficiency low, and prior art processing and fabricating trouble, and cost is high, easily hurts rupture disk in assembling process.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of air heating stove special anti-explosion valve.
The technological scheme that the utility model adopts is: a kind of air heating stove special anti-explosion valve, comprise explosion-proof valve seat, rupture disk and compression volution lid, described rupture disk is placed in explosion-proof valve seat and compresses between volution lid, it is recessed cylindric in cascade that rupture disk is, between explosion-proof valve seat and compression volution lid, be threaded connection, compress volution lid outside and be nut type, inner side cascade hollow, the inner isometrical hollow of explosion-proof valve seat, upper outside is to have the outside thread being connected with pipeline, middle part is provided with bulge loop, and bottom is provided with and the outside thread that compresses volution lid and be connected.
As the preferred embodiment of this programme, the outer circumferential side of described bulge loop be arranged with two be parallel to each other tighten access section.
Preferred embodiment as this programme, the cascade endoporus of described rupture disk be divided into two rank, compress the axles such as the endoporus of volution lid, explosion-proof valve seat hollow hole isometrical, the cascade endoporus diameter holes diameter of rupture disk is slightly less than and compresses the endoporus of volution lid, the diameter of explosion-proof valve seat hollow hole.
As the preferred embodiment of this programme, the foot of described explosion-proof valve seat is provided with the annular projection of apical grafting rupture disk second-order.
As the preferred embodiment of this programme, the endoporus of described compression volution lid, the diameter of explosion-proof valve seat hollow hole are 25mm.
Compared with prior art, the beneficial effects of the utility model are: processing and fabricating fast and easy, than at least fast 2 times of existing processing and fabricating speed on the market; Assembly and disassembly is easy damaged rupture disk fast and not, selects coming of new material can reduce product cost.
