Description
Technical field
The utility model relates to a kind of pressure relief device, relates in particular to a kind of explosion-proof valve.
Background technique
Explosion-proof valve is a kind of pressure relief device that compresses explosive pipeline, is widely used in the industry departments such as building materials, metallurgy, chemical industry, electric power, and it is simple in structure, mainly includes steel welding valve body and rupture disk.When the supercharging of internal system excessive pressure and while reaching rupture disk ultimate pressure, rupture disk moment breaks, and plays the effect of releasing pressure automatically, the blast of prevention system.In use be not difficult to find, rupture disk has some limitations: when explosion, produce certain fragment, wherein part fragment may enter in discharge conduit and the problem that results in blockage; Also have part fragment outwards to splash, there is larger impact force in himself, brings serious potential safety hazard simultaneously.
Model utility content
Technical problem to be solved in the utility model is to overcome the problems referred to above, prevents that explosion fragment from splashing or the explosion-proof valve of blocking pipe and provide a kind of.
The technical solution of the utility model is: a kind of explosion-proof valve described in the utility model, comprise valve body, be arranged on the flange of valve body lower end and be arranged on the rupture disk of valve body upper end, it is characterized in that: anti-blocking isolation net is installed on described flange No. one, and the periphery of a described anti-blocking isolation net is welded on flanged surface; Outside, described valve body upper end portion is arranged with an anti-splinter device, and described anti-splinter device is roughly the cylindric of up/down perforation, adopts corrugated flexible hose to make, and its lower end and valve body upper end are connected, and its upper end is free end and can stretches up and down along valve body short transverse; Described anti-splinter device upper end open place is also provided with anti-blocking isolation net No. two.In the time of rupture disk automatic-explosion, an anti-blocking isolation net that is positioned at valve body lower end can stop that fragment inwardly stops up relief pipeline, the anti-splinter device and No. two anti-blocking isolation nets that are positioned at valve body upper end can stop that fragment arbitrarily outwards splashes and makes fragment obtain certain buffer deceleration, and final fragment can leave in the cavity that explosion-proof valve body becomes with anti-splinter device institute shroud.
Further, anti-splinter device described in the utility model outside is provided with a banding ring, and described anti-splinter device lower end inwall is resisted against valve outer wall by the clamping of banding ring, reaches fastening effect, and is convenient to installation and removal.
Further, the material of anti-splinter device described in the utility model is composite elastic body resin material, there is certain elastic strain ability and good tear resistance, tensile strength, impact resistance, can carry out certain energy-absorbing buffering to the fragment contacting with anti-splinter device inwall.
Further, the thickness of anti-splinter device described in the utility model is greater than 5mm, avoids that tube wall is too thin and fragment impact power is excessive, causes tube wall to break.
The beneficial effects of the utility model are:
The utility model is in retaining original releasing pressure automatically effect, the fragment that explosion is produced can leave in the cavity that explosion-proof valve body becomes with anti-splinter device institute shroud, both can avoid fragment arbitrarily outwards to splash, and can stop again fragment and inwardly flow backward to relief pipeline and the problem that results in blockage.The utility model is simple in structure, is easy to dismounting and change, can clear up the safety that effectively guarantee is used and convenient in the time more renewing rupture disk to fragment simultaneously.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is further described:
Shown in Fig. 1, a kind of explosion-proof valve described in the present embodiment, mainly comprises valve body 1, is arranged on the flange 2 of valve body 1 lower end and is arranged on the rupture disk 3 of valve body 1 upper end.Wherein, anti-blocking isolation net 4 is installed on described flange 2 No. one, on a described anti-blocking isolation net 4, be evenly equipped with mesh, its periphery is welded on 2 of flanges, do not affect gas on the one hand and circulate normally, prevent that on the other hand the fragment of the rupture disk 3 explosions generations that are located thereon end from flowing back in relief pipeline.
In the present embodiment, described valve body 1 outside, upper end portion is also arranged with an anti-splinter device 5, and described anti-splinter device 5 is roughly the cylindric of up/down perforation, adopts corrugated flexible hose to make, its lower end and valve body 1 upper end are connected, and its upper end is free end and can stretches up and down along valve body 1 short transverse; Described anti-splinter device 5 upper end open places are also provided with anti-blocking isolation net 6 No. two, and its effect is similar with an anti-blocking isolation net 4, in not affecting gas communication, can prevent that fragment from splashing away from upper end-hole.In said structure, locking mechanism between described anti-splinter device 5 and valve body 1 is to realize by a banding ring 7, described banding ring 7 is set in anti-splinter device 5 outsides, and anti-splinter device 5 lower end inwalls are resisted against on the outer wall of valve body 1 by the snap action of banding ring 7.It should be noted that, the material of the anti-splinter device 5 described in the present embodiment is that composite elastic body resin material and its thickness are greater than 5mm, not only length is scalable to adopt the anti-splinter device 5 that this material manufactures, and shock-resistant, tear resistance, tensile strength are all very excellent.When explosion occurs, fragment non-directional splashes, wherein part fragment is stopped by anti-splinter device 5 and touches its inwall, there is certain elastic strain in anti-splinter device 5 now, play the effect of buffer deceleration, chip velocity is significantly reduced, and impact force reduces and stops that it splashes away from surrounding.Thus, under the comprehensive function of anti-blocking isolation net 4, No. two anti-blocking isolation nets 6 and anti-splinter device 5, the fragment that explosion produces can be contained in the cavity of above-mentioned three and 1 shroud formation of valve body, is convenient to process of aggregation, improves the safety reliability that explosion-proof valve uses.
Specific embodiment described herein is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under in every case and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
