Description
Technical field
The utility model relates to coal mine light concentration mash gas pipeline delivery safety back-fire relief facility, particularly a kind of bubble-cap type overflow water seal fire arrestor.
Background technology
During the coal mine gas safe transport, on the coal mine light concentration mash gas feed-line, the water-sealing fire-retardant explosion venting device must be installed, in the situation of catching fire of blasting, can stop effectively that flame particularly propagates under the coal mine to the source of the gas end, and elevated pressures in the delivery system.Existing gas tube water-sealing fire-retardant explosion venting device, its structure is that single large elbow inserts water seal, for the coal mine gas delivery safety has been brought into play important function, but it exists following shortcoming or deficiency simultaneously: 1. sealing structure for water is that single large elbow inserts sealing structure for water, form easily larger bubble and break, cause the gas pressure fluctuation larger; 2. passive type monitoring water seal liquid level, and control is interrupted the benefit draining, and control system is comparatively complicated, breaks when causing the water seal level fluctuation comparatively frequent at water sealing (sealing water) pipe outlet air pocket, and the water seal liquid level keeps relatively difficulty; When 3. gas pressure is too high, can not reliably discharge manifold pressure, have potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of improved bubble-cap type overflow water seal fire arrestor, employing in the spark arrester tank body, arrange many group bubble-cap type overflow valves, control water seal height downflow weirs, the structure that the water seal liquid level gauge is monitored etc. the water seal liquid level is set, in spark arrester, to continue the mode for backwater, and by the overflow effect, guarantee that the water seal liquid level is constant, the shortcoming or the deficiency that namely effectively overcome or avoid existing in the above-mentioned prior art, effectively make again the relief valve group at spark arrester top diffuse the reliable pressure release of pressure by setting, guarantee gas safety.
Bubble-cap type overflow water seal fire arrestor described in the utility model comprises tank body.Described tank body is upper shell and lower house two body Integral type structures, upper shell and lower house are fixed together by upper sealing flange and lower seal flange, arrange on the wall of lower house water seal water replenishing mouth, water seal drainage mouth, gas import, gas export, water seal liquid level gauge are installed, lower house bosom horizontal direction is equipped with water seal; Setting is equipped with in spring pre-tightening type relief valve group, the guide post spring pre-tightening type relief valve group preloading spring group is installed on the upper shell, and tank base is equipped with swash plate.
Wherein, described water seal comprises that the overflow valve group that horizontal direction is installed supports fixed head and upper many groups bubble-cap type overflow valve group of installation and the downflow weir of control water seal height arranged thereof.Between described upper sealing flange and lower seal flange sealing strip is set, compresses by the preloading spring group.Described gas import is installed on the overflow valve group and supports on the lower house between fixed head bottom, the swash plate.Be installed on described gas export lower seal flange and overflow valve group support on the lower house between the fixed head.Described water seal water replenishing mouth is installed on the middle and lower part of lower house, is connected with the water seal liquid level gauge.
The utility model has following advantage compared with prior art:
1, device in Gas through water seal, enters the spark arrester upper space by bubble-cap type overflow valve group, when playing the effect of water seal isolation back-fire relief, air flow is refined as little airflow, gas pressure and water seal liquid level held stationary.
2, employing continues supply and return water mode in spark arrester, and by the overflow effect, guarantees that the water seal liquid level is constant.
3, spring pre-tightening type relief valve group plays the safety relief effect, and pressure release is safe and reliable.
4, be designed with the water seal liquid level gauge on the tank body, monitoring water seal water level can show on the spot, but also remote liquid level signal.
5, adopt lasting spark arrester interior for backwater, and by the overflow effect that said structure forms, guarantee that the water seal liquid level is constant.
6, overpressure protection, when the gas pressure superpressure, the preloading spring group in the spring pre-tightening type relief valve group is compacted; upper sealing flange under the guide post guide effect by jack-up; diffuse the gap with the formation of lower seal flange and diffuse, when gas pressure recovers normal, recover sealing state.
7, rational in infrastructure, safe and reliable, economical and practical.
