Abstract
The utility model discloses a gas pressure segmented automatic-control large-quantity device, which consists of a barrel body (1), a water-supply pipe (2), a water-drainage pipe (3), a gas downspout (4), an outlet pipe (5) and a manhole (6). The device is characterized in that a horizontal water-spilling section (7) of the water-drainage pipe (3) is provided with an upper section, a middle section and a lower section, which are opposite to three water-level height h1, h2 and h3 and are respectively provided with electromagnetic valves (8, 8.1, 8.2); corresponding different gas pressure of the three sections, three pressure sensors (9, 9.1, 9.2) are arranged inside the upper pipeline of the gas downspout (4), and the three pressure sensors are respectively connected with the upper, the middle and the lower electromagnetic valves (8, 8.1, 8.2) through relative conducting wires (10, 10.1, 10.2). Since adopting the gas pressure segmentation and being provided with an automatic on-off valve that is synchronic with the variation of the gas pressure, the variation of the water level can be synchronic with the variation of the gas pressure, thereby being more suitable for the fluctuation of the gas and improving the water-sealing effect.
Description
Technical field
The utility model relates to a kind of improvement of gas pressure segmentation bleeding device, particularly a kind of can be according to gas pressure size in the pipeline, the big bleeding device of the self-adjustable gas pressure segmentation of its valve automatic control.
Background technique
At present, enterprise's automatic bleeding device of employed coal gas has two kinds: a kind of is that water seal is diffused, suitable little coal gas diffusion; Another kind is to adopt automatic valve or quick opening valve to control.Adopting automatic valve control, is that the pressure design with gas pipe line becomes stationary value, when gas pressure during greater than setup pressure value, automatic valve is opened, when gas pressure during less than setup pressure value, automatic valve is closed, and the pressure stability that makes coal gas system within the specific limits; Adopt quick opening valve to control, its structure comprises staving, water pipe, waste pipe, the coal gas sink drain, steam outlet pipe, access opening constitutes, water level in its staving is controlled by manual quick opening valve, need this moment the pressure of gas pipe line is set discharge pressure value in the scope of P1-P2, when gas pressure when setting discharge pressure P1, manually quick opening valve is opened, when gas pressure is set discharge pressure P2 less than discharging, manually quick opening valve is closed, by opening or closing of manual quick opening valve, control water level, the pressure stability that makes coal gas system is between pressure P 1 to P2.Generally, gas pressure can be divided into three sections, manual quick opening valve of every section correspondence.The deficiency of the manual quick opening valve control water level of this employing is: the one, and inconvenient operation; The 2nd, if during the fast dryvalve door of the untimely switch of operator, the gas pressure in the gas pipe line can produce very great fluctuation process, this be Gas Production and use in important unsafe factor; The 3rd, the variation poor synchronization that open or close and the coal gas of manual quick opening valve is pressed.
Summary of the invention
The purpose of this utility model is to provide a kind of method that adopts gas pressure segmentation and autocontrol valve to open or close, and it is synchronous to realize that height of water level changes with variation in pressure, thereby improves the big bleeding device of gas pressure segmentation automatic control of coal gas sink drain water seal effect.
For reaching above purpose, the technological scheme that the utility model adopted is: the big bleeding device of this gas pressure segmentation automatic control, by staving, water pipe, waste pipe, the coal gas sink drain, steam outlet pipe and access opening constitute, access opening is located at the bottom of bucket outer wall, the coal gas sink drain inserts the bottom in the staving, steam outlet pipe is drawn from the top of staving, water pipe enters in the staving from the outer wall top of staving, and insertion staving inner bottom part, the vertical section of waste pipe in staving also inserts the staving inner bottom part, the horizontal spilling water section that it is characterized in that waste pipe is established, in, following three sections, corresponding three height of water level h
