Problems solved by technology

But this way is ok in the south, but it can't be used in the north
In the traditional emergency release of this kind of rubber membrane-sealed gas holder in the north, there are often accidents caused by gas leakage, and some people are even poisoned for this. If the pressure of the cabinet is higher than 10kPa, it will not work to make up for it by water seal, and the weight of the cover plate 2' is too heavy, so its sealing becomes a problem

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment 。

[0019] Such as figure 2 and image 3 as shown,

[0020] When the gas tank piston 2 does not reach the top, due to the effect of the elastic device 7, the first travel switch spool piston 11 and the second travel switch spool piston 10 are in the figure 2 At this time, the gas under pressure in the emergency release pipe passes through the travel switch gas pipeline, passes through the first travel switch spool piston 11, enters the opening and closing valve body 3, and is pushed into the opening and closing valve body 3 by the action of gas. The piston 4 and the sealing plate 5 achieve the closing effect. In order to allow the piston 4 to move smoothly, the gas in the other cavity of the on-off valve body 3 passes through the first transverse through hole of the second stroke switch spool piston 10 and enters the outlet part of the emergency r...

Abstract

The invention discloses an emergency automatic diffusing device for a gas chamber. The emergency automatic diffusing device is characterized by comprising an emergency diffusing pipe which is provided with a rain-proof cap on the top, wherein an opening / closing valve body with a piston inside is arranged on one side of the emergency diffusing pipe; the piston is connected with a sealing plate forenclosing the emergency diffusing pipe; a travel switch valve body is arranged above a gas chamber piston, and is provided with cavities for accommodating a first travel switch valve plunger piston and a second travel switch valve plunger piston respectively; the top of each travel switch valve plunger piston is provided with an elastic device; and each travel switch valve plunger piston can moveup and down in the cavities, and is in hermetic seal with cavity walls. The emergency automatic diffusing device is safe and reliable, can adapt to a gas chamber with a high pressure, and can be wellsealed and opened / closed no matter how high the coal gas pressure is. Due to the adoption of the emergency automatic diffusing device, the running adaptability of the piston is greatly enhanced, the service life of the gas chamber is prolonged, and the service life of a hermetic rubber film is prolonged.

Description

technical field [0001] The invention relates to a gas cabinet, in particular to an automatic release device in the gas cabinet. Background technique [0002] Rubber-membrane-sealed gas cabinets, also known as membrane cabinets or Wiggins cabinets. The sealing of this kind of gas holder relies on the rubber membrane, because this type of gas holder has its own characteristics: the piston runs at a fast speed, usually exceeding 5m / min, and it can adapt to the occasion of large throughput, which is rare Oil-tight gas holders are difficult to achieve; secondly, this kind of gas holder is sealed by rubber membrane, without liquid, let alone water, which is very popular in the north; The dust content is not as strict as that of thin oil tanks; fourthly, the working stability of this kind of gas tank is higher than that of thin oil tanks. In this way, under the same conditions, this kind of gas tank can save a part of energy. It is more favored by users under the condition of att...
