Abstract
The utility model discloses a sealing device used in storages with inflammable, explosive, volatile and toxic gas, which solves the problems of being stainless and easy to generate static charge under special environments of not allowing electrifying or spark of the existing gas sealing devices. The utility model comprises a gas storage orifice, a flange and a gasket. The gasket is arranged between the gas storage orifice and the flange. A connector is connected on the inner wall of the gas storage orifice, a sealing body is arranged in the connector and a cavity body is connected in the connectors through a screw thread, an air inlet cover is connected to the top of the cavity body and a filter-suck body is arranged in the cavity body; an oil and gas hole running through the cavity body and communicating with an inner cavity of the storage is arranged at the inner sidewall of the cavity body, and an oil and gas hole running through the air inlet cover and communicating with the inner cavity of the storage is arranged at the top wall of the cavity body. The utility model can realize to guarantee seal and no static charge generating in special environments, for example, inside and outside pressure difference and gas leakage of the gas storage.
Description
[technical field]
The utility model relates to a kind of seal arrangement, a kind of specifically seal arrangement that uses in inflammable, explosive, volatile, toxic gas storage is housed.
[background technique]
Storage inflammable, explosive, volatile, toxic gas is housed has grown standing time, in the storage inner chamber, oil gas adheres to formation one deck oil film on the storage intracavity sidewall, and oil film flows down along tube wall, is accumulated in storage mouth of pipe place; And under particular surroundings,, need to install seal arrangement as not allowing energising, having under the condition such as spark generation.Present gas reservoir only is equipped with sealing gasket between the gas reservoir mouth of pipe and flange, this encapsulating method changes in ambient temperature, and make when forming pressure reduction inside and outside the gas reservoir, the gas in the storage will and can produce static along the sealing gasket seepage, must in time be got rid of.
[summary of the invention]
The utility model has overcome the shortcoming of prior art, has solved existing gas-tight sealing sternly, does not easily produce static at the particular surroundings lower seal problem.
The utility model seal arrangement comprises the gas reservoir mouth of pipe, flange, sealing gasket, between the gas reservoir mouth of pipe and the flange sealing gasket is housed, and is connected with coupling on gas reservoir mouth of pipe inwall, is provided with seal in the coupling; With scyewed joint cavity is arranged in coupling, the cavity top attachment has Intake Cover, filter is housed in the cavity inhales body; Have at the cavity madial wall and to run through the oil-gas hole that cavity communicates with the storage inner chamber, have at the cavity roof and run through the oil-gas hole that Intake Cover communicates with the storage inner chamber.
The utility model can be implemented under the particular surroundings, when draught head, gas permeation are arranged inside and outside gas reservoir, guarantees sealing and can not produce static.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[embodiment]
The utility model comprises the gas reservoir mouth of pipe 6, flange 9, sealing gasket 10, between the gas reservoir mouth of pipe 6 and the flange 9 sealing gasket 10 is housed, and is connected with coupling 2 on the gas reservoir mouth of pipe 6 inwalls, is provided with seal 3 in the coupling 2; With scyewed joint cavity 1 is arranged in coupling 2, there is Intake Cover 5 at cavity 1 top with scyewed joint, is equipped with in the cavity 1 by the filter heat insulation, fire-retardant, that insulating material is made to inhale body 4; Have at cavity 1 madial wall and to run through the oil-gas hole 11 that cavity 1 communicates with storage inner chamber 8, have at cavity 1 roof and run through the oil-gas hole 12 that Intake Cover 5 communicates with storage inner chamber 8.The effect of oil-gas hole is when inside and outside the gas reservoir draught head being arranged, and makes the gas in the storage breathe and filter air-breathing liquid.
The oil-gas hole 11 that cavity 1 madial wall has is a circle, at least two; The oil-gas hole 12 that cavity 1 roof has is at least one.
Body 4 is inhaled in cavity 1, filter, Intake Cover 5 constitutes integral body, can whole unloading down.
Seal process is: in variation of ambient temperature, and make when forming pressure reduction inside and outside the gas reservoir, between the inner chamber of the utility model cavity 1 and storage inner chamber 8, produce draught head, the filtration suction-operated that inhale body 4 pair gases and oil film mixture by filter in the cavity 1 this moment, make the mixture generation resistance of gas and oil film stifled, reach dynamic seal (packing).
Claims (2)
1, a kind of seal arrangement, comprise the gas reservoir mouth of pipe, flange, sealing gasket, between the gas reservoir mouth of pipe and the flange sealing gasket is housed, it is characterized in that: on the gas reservoir mouth of pipe (6) inwall, be connected with coupling (2), be provided with seal (3) in the coupling (2); With scyewed joint cavity (1) is arranged in coupling (2), cavity (1) top attachment has Intake Cover (5), filter is housed in the cavity (1) inhales body (4); Have at cavity (1) madial wall and to run through the oil-gas hole (11) that cavity (1) communicates with storage inner chamber (8), have at cavity (1) roof and run through the oil-gas hole (12) that Intake Cover (5) communicates with storage inner chamber (8).
2, seal arrangement according to claim 1 is characterized in that: the oil-gas hole (11) that described cavity 1 madial wall has is a circle, at least two; The oil-gas hole (12) that cavity (1) roof has is at least one.
