Abstract
The utility model provides an explosion-proof valve for an industrial flame furnace. The explosion-proof valve for an industrial flame furnace comprises a base, a release plate, a supporting bar, and a protective cover. The base is fixed by a connection pipe, and the release plate is matched with the base, and the release plate is provided with an applicator. The supporting bar is fixed with the base through the release plate, and the supporting bar is provided with a spring. The protective cover is connected with the supporting bar. The explosion-proof valve has simple structure and long service life. The explosion-proof valve is easy to switch on, off and reset. The explosion-proof valve can efficiently prevent the explosions of a furnace hearth of an industrial furnace, a combustion supporting air pipe and gases able to explode in the smoke pipe.
Description
The utility model relates to a kind of explosion-proof valve, particularly relates to a kind of industrial flame furnace explosion-proof valve.
The present spring explosion-proof valve that adopts on the domestic various industrial furnaces, spring is contained on the strut, but unshielded cover on the strut causes spring life to shorten, and is plane sealing between pedestal and the release board, and sealing is relatively poor.In addition, but when the explosive gas explosion time, can tilt to be stuck on the strut because of the explosive power skewness causes release board, it is dumb that release board is opened, and is only applicable to the industrial furnace of micro-pressure operation.
The purpose of this utility model is to provide a kind of uniformly distributed device that is provided with, and protective housing and shell are opened flexibly the industrial flame furnace explosion-proof valve of long service life.
The utility model industry flame furnace explosion-proof valve is to realize like this, it comprises connecting tube, fixes the pedestal that has groove on its periphery with connecting tube, and is general fixing with welding, cooperate release board with protruding circle with base recess, seal washer is arranged therebetween, form tortuous sealing, gas is not leaked, pass release board and pedestal is fixed, and the strut that is the 3-4 piece of band spring that regular polygon distributes when big, can be provided with 4 pieces as the release board area thereon.Post upper is fixed with protective housing, is used to limit the release board mobile position.Thereby restraining spring is compressed degree, makes it be no more than elasticity and limits the quantity of, and prolongs spring working life.Be connected with uniformly distributed device on the release board, be advisable, the explosion time air-flow can evenly be discharged around release board with taper shape.Also a shell can be set on release board, to prevent that spring is by pollution or corrosions such as dusts.
The industrial principle of the utility model industry flame furnace explosion-proof valve is, when furnace pressure increases to a certain degree, gas forms space and pressure spring by moving on the connecting tube pushing tow release board, because the effect of uniformly distributed device can evenly discharge air-flow around release board, the active force of spring can make release board recover its origin-location again when furnace pressure reduces.
The advantage of the utility model industry flame furnace explosion-proof valve is simple in structure, safe and reliable, release board is opened flexibly, can run-off the straight or be stuck on the strut, good airproof performance, long service life, it is explosion-proof not to be only applicable to pressurized furnace, is applicable to that also working pressure is 0.2kgf/cm2 explosion-proof with interior industrial flame furnace and combustion-supporting airduct and smoke pipe.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Fig. 1: the utility model structural representation
The utility model industry flame furnace explosion-proof valve comprises connecting tube 1, have the pedestal 3 of groove on the fixing and periphery with connecting tube 1, cooperate on its periphery release board 5 with protruding circle with pedestal 3, therebetween seal washer 4, the uniformly distributed device 2 that is connected with release board passes release board 5 and is the equilateral triangle distribution, and be connected with foundation bolt, and the strut 6 of band spring 7 is fixed on the protective housing 8 of strut 6 upper ends, and is fixed on the shell 9 on the release board 5.
Claims (2)
1, a kind of industrial flame furnace explosion-proof valve comprises connecting tube, with the fixing pedestal of connecting tube, the release board that cooperates with pedestal, be arranged on the supporting element of band spring on the release board, it is characterized in that having groove on the pedestal periphery, the protruding circle with groove fit is arranged on the release board periphery, seal washer is arranged therebetween, be connected with uniformly distributed device on the release board, strut 3-4 piece, pass release board and pedestal is fixed, and be regular polygon and distribute, post upper is fixed with protective housing.
2, industrial flame furnace explosion-proof valve as claimed in claim 1 is characterized in that release board is provided with shell.
