Abstract
The utility model relates to gas producer bleeding device, particularly a kind of coal gas diffusion bell jar control valve unit.Comprise belljar valve housing, bell jar, suspension rod, coal gas diffusion inlet ductwork, coal gas diffusion export pipeline, sewage draining exit pipeline, belljar valve lower housing portion is provided with sparge water inlet ductwork; Sewage outfalls setting is in the bottom of belljar valve housing.In such scheme, rushing Xian's water inlet pipeline is normally open, and be built-in with circulating water, circulating water is often opened; Sewage draining exit is placed in belljar valve housing bottom, and the tar and the dust that are beneficial to bottom are discharged with circulating water.
Description
Technical field
the utility model relates to gas producer bleeding device, particularly a kind of coal gas diffusion bell jar control valve unit.
Background technique
in the operating process of gas producer, some stove, blowing out, hot standby reincarnation is produced, produce when turning hot standby and accident or have a power failure time all to carry out coal gas diffusion, the coal gas diffused is discharged by gas bleeding valve.
tradition diffusion valve mostly is bell jar valve type structure (structural type is as accompanying drawing 1), and water seal dish is arranged at bottom, topped up with water in water seal dish.During belljar valve work, moved up and down in bell jar housing by bell jar, can set up in belljar valve housing and remove water seal.When bell jar moves to position, under bell jar, edge is higher than water seal liquid level, and diffuse water seal and remove, coal gas starts to diffuse; When bell jar moves to upper/lower positions, under under bell jar, edge is dipped in water seal liquid level, diffuse water seal and formed, coal gas diffusion stops.
when gas producer diffuses, belljar valve is in running order, and along with coal gas constantly passes through in belljar valve, the tar in coal gas drips and can deposit in water seal dish with dust, and water seal dish top is provided with drags for grey mouth, and operator regularly carries out dragging for ash manipulation.When gas producer operation is abnormal, gas pressure increases suddenly sometimes, and in water seal dish, water seal water can spray, although be beneficial to compensator or trimmer pressure, can pollute surrounding environment.
Summary of the invention
goal of the invention of the present utility model is to provide can the coal gas diffusion bell jar control valve unit of automatic pollution discharge.
the utility model adopts following technological scheme:
a kind of coal gas diffusion bell jar control valve unit, comprise belljar valve housing, bell jar, suspension rod, coal gas diffusion inlet ductwork, coal gas diffusion export pipeline, sewage draining exit pipeline, belljar valve lower housing portion is provided with sparge water inlet ductwork, and sewage outfalls setting is in the bottom of belljar valve housing.
in such scheme, rushing Xian's water inlet pipeline is normally open, and be built-in with circulating water, circulating water is often opened; Sewage draining exit is placed in belljar valve housing bottom, and the tar and the dust that are beneficial to bottom are discharged with circulating water.
the preferred version that the utility model adopts is:
sparge water inlet ductwork is tangentially connected with belljar valve housing.Tangential coupled condition, makes current rotate in belljar valve housing.
Accompanying drawing explanation
fig. 1 is the structural representation of prior art.
in Fig. 1: emission coal gas import 1, water seal dish 2, disk cover 3, emission coal gas outlet 4, bell jar and suspension rod 5, belljar valve main body 6, suspension rod seal arrangement 7, pull unit 8.
fig. 2 is structural representation of the present utility model.
fig. 3 is the plan view of Fig. 2.
Embodiment
below in conjunction with drawings and Examples in detail the utility model is described in detail:
a kind of coal gas diffusion bell jar control valve unit, see in accompanying drawing 2 to accompanying drawing 3, figure: sewage draining exit 1, sparge water inlet ductwork 2, coal gas diffusion import 3, coal gas diffusion outlet 4, suspension rod 5, belljar valve housing 6, lifting sealing put 7, pull unit 8, bell jar 9.
in the present embodiment, belljar valve housing 6 bottom is provided with sparge water inlet ductwork 2; Sewage draining exit 1 is arranged on the bottom of belljar valve housing 6.Sparge water inlet ductwork 2 is tangentially connected with belljar valve housing 6.
add water to regulation liquid level in belljar valve housing 6, bell jar 9 and suspension rod 5 are when low level, and bell jar 9 and suspension rod 5, belljar valve housing 6 form water seal body.Belljar valve housing 6 is provided with coal gas diffusion import 3 and coal gas diffusion outlet 4.When gas station normally works and do not diffuse, bell jar 9 and suspension rod 5 are at low level, and bell jar water seal seals coal gas, make it not leak.When gas pressure transfinites, gas pressure is enough to the gravity overcoming bell jar 9 and suspension rod 5 etc., and back down bell jar 9, coal gas is released by discharging opening 4, protects other equipment of gas station.When needing emission coal gas in gas station operating process, pull pull unit 8, bell jar 9 and suspension rod 5 are carried, coal gas flows out from coal gas diffusion outlet 4 and diffuses.
in coal gas diffusion belljar valve device, water seal water is circulating water, and circulating water is often opened, and water seal circulating water is tangentially entered along belljar valve housing 6 by sparge water inlet ductwork 2, and current are rotated in belljar valve housing 6; Water seal circulating water is discharged by the sewage draining exit 1 opened bottom belljar valve housing 6, and the tar and the dust that are sunken to bottom are discharged with circulating water.
belljar valve housing 6 in the present embodiment eliminates cleaning and drags for grey mouth, and when preventing gas pressure from increasing suddenly, water seal water is excessive, improves gas station environment.Have: good sealing effect, can automatic pollution discharge, structure is simple, Safety performance is high, avoid operating environment of pollution and facilitate the advantages such as operative.
