Abstract
The utility model discloses an explosion-proof valve, which comprises a flange, a valve body, a rupture disk, a gland and a cross protector, wherein the flange is mounted below the valve body, the rupture disk is connected onto the valve body, the gland arranged outside the rupture disk is connected with the valve body, and the cross protector is mounted on the gland. The novel explosion-proof valve has the advantages of simple structure, convenience for installation, safety use and capability of preventing a pipeline system for compressing explosive gases from exploding.
Description
Technical field
The utility model relates to a kind of pressure relief device, is specifically related to a kind of pressure relief device as compression explosion hazard gases pipeline.
Background technique
Before B.C. bimillennium, China has just used bamboo trunk and stopper valve on aqueduct, and along with the not section development of society and the needs of productive life, pipeline is tried to be the first to develop by all trades and professions and used.Because internal pipe pressure is excessive, explosion takes place in pipeline easily, can not get on the safety ensureing.
Domestic explosion-proof valve all adopts the steel welding structure mostly at present.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of new type explosion proof valve simple in structure, easy for installation, safe in utilization to be provided, and can prevent that the pipe-line system of compressing explosion hazard gases from blasting.
The technical solution adopted in the utility model is: a kind of explosion-proof valve; it comprises flange, valve body, rupture disk, gland and cross protector; described valve body below is equipped with flange; be connected with rupture disk above the valve body; described gland is arranged on the rupture disk outside; and be connected with valve body, described cross protector is installed on the gland.
When transportation, can on gland, connect a cross protector, so that transportation and installation with screw; In use, remove the cross protector, so that use and safety.
The beneficial effects of the utility model: 1. when pipeline pressure was excessive, rupture disk explosion automatically reached the purpose to the pipeline pressure release, thus safety in production better; 2. need not power supply, releasing pressure automatically. simple in structure, reliable performance, easy for installation; 3. adopt the steel welding structure, but on this basis, upgrade again, increased detachable apparatus, can guarantee safety and the convenience used better.
