Abstract

The invention discloses an explosion venting valve. The explosion venting valve comprises a valve body, a clamp holder and a valve deck. The clamp holder is fixed to the upper end of the valve body. A support is fixed to the lower end of the valve body through a bolt. A rupture disk is installed inside the valve body. A connecting flange is installed at the rear end of the valve body. A sealing face is installed on an opening portion of the valve body. A connecting rod is installed on the clamp holder. An adjusting hand wheel is installed at the upper end of the connecting rod. A valve deck is fixed to the middle of the connecting rod. A counter weight is fixed to the lower end of the connecting rod. A sealing ring is arranged outside the valve deck. The explosion venting valve has the advantages that after the rupture disk explodes at the first time, the function is achieved by the sealing face, and the sealing face is tightly combined with the sealing ring on the valve deck so that air can not enter a device and safety can be improved.

Description

A kind of explosion-released valve
Technical field
The present invention relates to a kind of valve, relate in particular to a kind of explosion-released valve.
Background technique
Explosion-released valve is during for system overpressure, and rupture disk breaks, moment pressure release, and valve gap resets after upspringing under Action of Gravity Field, is mainly applicable to the industry departments such as building materials, metallurgy, oil, chemical industry.For explosion-released valve, sealing is very important, otherwise explosion-released valve after venting of dust explosion, sternly and does not still enter air by sealing for the first time in equipment, just can cause larger for the second time blast, therefore, needs a kind of technological scheme to address the above problem.
Summary of the invention
The invention provides a kind of explosion-released valve of good airproof performance.
The technical solution used in the present invention: a kind of explosion-released valve comprises valve body, clamp holder and valve gap, valve body upper end is fixed with clamp holder, valve body lower end has been bolted supporting frame, and valve inner is provided with rupture disk, and valve rear end is provided with adpting flange, valve body openings place is provided with sealing surface, connecting rod is installed on clamp holder, and connecting rod upper end is provided with adjustment handwheel, is fixed with valve gap in the middle of connecting rod, connecting rod lower end is fixed with weight, and valve gap outside is provided with seal ring.
Above-mentioned seal ring is that ethylene propylene diene rubber is above-mentioned, and stating sealing surface is teflon rubber.
Beneficial effect of the present invention: after rupture disk explosion for the first time, sealing surface just can play a role, and the seal ring on sealing surface and valve gap fits, causes the air cannot access arrangement, and Safety performance is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1, valve body, 2, clamp holder, 3, valve gap, 4, rupture disk, 5, weight, 6, supporting frame, 7, adjust handwheel, 8, connecting rod, 9, bolt, 10, seal ring, 11, adpting flange, 12, sealing surface.
Embodiment
As shown in Figure 1, a kind of explosion-released valve comprises valve body 1, clamp holder 2 and valve gap 3, and valve body upper end is fixed with clamp holder 2, and valve body lower end is fixed with supporting frame 6 by bolt 9, valve inner is provided with rupture disk 4, valve rear end is provided with adpting flange 11, and valve body openings place is provided with sealing surface 12, and connecting rod 8 is installed on clamp holder 2, connecting rod 8 upper ends are provided with adjusts handwheel 7, in the middle of connecting rod 8, be fixed with valve gap 3, connecting rod 8 lower ends are fixed with weight 5, and valve gap 3 outsides are provided with seal ring 10.
Above-mentioned seal ring 10 is that ethylene propylene diene rubber is above-mentioned, states sealing surface 12 for teflon rubber.
Beneficial effect of the present invention: after rupture disk 4 explosion for the first time, sealing surface 12 just can play a role, sealing surface 12 fits with the seal ring 10 on valve gap 3, causes the air cannot access arrangement, and Safety performance is high.
