Abstract

The utility model belongs to the air discharging device technical field. The external contour of one end face of a circular-pipe-shaped valve seat is a square plate which is provided with four uniformly distributed bosses. The center of each boss is provided with a threaded hole. The periphery of a valve body is composed of an upper plane and a conical surface. The valve body is a beveling valve body with a narrow upper part and a wide lower part. One valve body end face matching the valve seat is provided with four uniformly distributed unthreaded holes while the other end face matching a valve plate is provided with a circular groove inside. A hinge internal seat is riveted on the upper plane. The two sides of the valve body are internally provided with bosses. The center of each boss is provided with a threaded hole. A locking piece which is respectively riveted on the two sides of the valve body is screwed by screws on the built-in bosses. The valve plate is a plate formed by an upper chord line and a majority of a circle. The periphery of the valve plate is provided with a circular hook which matches the valve body. A hinge external seat is riveted on the valve plate. A hook-shaped fusible sheet is equipped in the hinge internal seat through screws and nuts. The central connecting part of a duplex torsion spring is inserted into the hook-shaped fusible sheet. A pivot pin screw traverses the hinge external seat, the hinge internal seat, the duplex torsion spring and a sleeve and is screwed by a nut. A single-valve-plate double-action non-return fire-resistant valve is formed after the valve seat and the valve body are screwed by screws. Another single-valve-plate double-action non-return fire-resistant valve with an obliquely vertically equipped and laterally arranged hinge is basically the same to the single-valve-plate double-action non-return fire-resistant valve with a horizontally equipped and upwardly arranged hinge as mentioned above.

Description

One valve block double-action non-return fire insulation valve
Technical field the utility model belongs to the air exhausting device technical field, is a valve block double-action non-return fire insulation valve.
The background technique safety check is used for the passive unidirectional air draft of pipeline supplies gas, and fire insulation valve is used for pipeline to be play every the effect of cigarette back-fire relief.From existing non-return, fire insulation valve structure, though the shared valve body of two valves for realizing unidirectional air draft and meeting the various objectives that fire intercepts, generally all is two cover mechanisms, two valve blocks, complex structure not only, and also axially volume is big.Therefore, need to consider to play unidirectional air draft effect at ordinary times, intercept the new structure of pyrotechnics when meeting fire rapidly with a cover mechanism, a valve block.
