Description
Technical field
A kind of gas piping drainage arrangement is the utility model is related to, particularly a kind of anti-suck supercharging coal gas drainer.
Background technology
Contain certain moisture in coal gas, be in gaseous state when temperature is high, condensed water is condensed into when temperature is low.Coal gas draining
Device is mainly used in collecting and discharges the condensed water in gas piping, avoid after gas piping ponding with the etchant gas knot in coal gas
Symphysis, so as to corrosion pipeline, plays an important role into deep-etching liquid in the safe operation of gas piping.Coal gas drainer
Operation principle is to overcome gas pressure using water seal height, plays a part of preventing gas leak during draining.One kind is usually used in steel
Factory, the coal gas drainer of coke-oven plant's gaspipe network, four chambers are provided with the shell of water trap, this four chambers water trap can
To increase the pressure at expulsion of gas leak, but the water trap of common four chambers structure when gas pressure fluctuates because of gas pressure
Rise still has the hidden danger of gas leakage.
Utility model content
The purpose of this utility model is the drawback for prior art, there is provided one kind can increase gas leak resistance and prevent
Sealing flows backwards the anti-suck supercharging coal gas drainer into gas piping.
Problem described in the utility model is realized with following technical proposals：
A kind of anti-suck is pressurized coal gas drainer, including shell, and four chambers by pipeline communication, first case are provided with shell
Ceiling portion is provided with the flange of connection gas piping, and the top of last chamber is provided with the overfall of connection drainage pipeline, set in last chamber
There is unidirectional opening structure, unidirectional opening structure includes dividing plate, valve port and cover plate, and dividing plate is located at overfall and the water inlet of last chamber
Between, last chamber is divided into two upper and lower chambers by dividing plate, and valve port is arranged on dividing plate, and dividing plate top soldering free bearing, cover plate is covered in
At valve port, one end and the free bearing of cover plate are hinged.
Above-mentioned anti-suck is pressurized coal gas drainer, and the valve port is obliquely installed, the axis of valve port and the angle of vertical direction
For 10-15 °.
Above-mentioned anti-suck is pressurized coal gas drainer, and the contact surface of the cover plate and valve port is provided with rubber gasket, and rubber is close
Packing is affixed with cover plate.
Above-mentioned anti-suck is pressurized coal gas drainer, and the unidirectional opening structure uses stainless steel.
The utility model has the problem of gas leak hidden danger in pressure oscillation for common coal gas drainer to be carried out
Improve, set up unidirectional opening structure in the last chamber of four chamber coal gas drainers, the metal cover board of unidirectional opening structure relies on certainly
Cover again at valve port, effectively increase gas leak resistance, prevent from producing leakage when gas pressure fluctuates；In addition, work as gas piping
During negative pressure, cover plate is fitted tightly over valve port, prevents aqueous reflux from entering gas piping.The utility model is simple in construction, it is easy to accomplish,
Convenient to carry out, using effect is good, can improve its functional reliability and security by the transformation to existing coal gas drainer.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is top view of the present utility model；
Fig. 2 is Figure 1A-A sectional views；
Fig. 3 is Figure 1B-B sectional views (rotation)；
Fig. 4 is the schematic diagram of unidirectional opening structure.
Each list of reference numerals is in figure：1st, shell, 2, first chamber, 3, flange, 4, last chamber, 5, overfall, 6, unidirectional open
Structure, 6-1, dividing plate, 6-2, free bearing, 6-3, cover plate, 6-4, rubber gasket, 6-5, valve port.
Embodiment
Referring to Fig. 1-3, anti-suck described in the utility model supercharging coal gas drainer includes shell 1, in shell provided with by
Four chambers of pipeline communication, the top of first chamber 2 are provided with the flange 3 of connection gas piping, and the top of last chamber 4 is provided with connection
The overfall 5 of drainage pipeline.Condensed water in gas piping enters after first chamber sequentially enters each chamber through pipeline, then by end
The overflow valve discharge of chamber.
Referring to Fig. 2, Fig. 4, to increase the resistance of gas leak, the utility model is additionally arranged unidirectional opening structure in last chamber
6.Unidirectional opening structure includes dividing plate 6-1, valve port 6-5 and cover plate 6-3, dividing plate be located at overfall and last chamber water inlet it
Between, last chamber is divided into two upper and lower chambers by dividing plate.Cylindric valve port and dividing plate soldering, in dividing plate top soldering free bearing 6-2,
Cover plate is covered at valve port by deadweight, and one end and the free bearing of cover plate are hinged.To make cover plate more easily be covered in valve port top,
Valve port is obliquely installed, and the axis of valve port and the angle of vertical direction are 10-15 °.To improve the sealing of valve port, in cover plate and valve
The contact surface of mouth is provided with rubber gasket 6-4, and rubber gasket fixes as one through screw and adhesive with cover plate.It is unidirectional to open
In the water of structure long-term work, to avoid because of corrosion, each part of unidirectional opening structure is prepared using stainless steel.
The utility model is overcoming the basis of gas pressure by water seal height in use, anti-suck is pressurized coal gas drainer
On add gas leak resistance, the when of rise when gas pressure fluctuates, unidirectional opening structure is formed again to the coal gas of leakage
One of barrier, thus improve the functional reliability and security of coal gas drainer；In addition gas piping low pressure or during negative pressure, lid
Plate pressure below is less than the gravity of water above cover plate, and cover plate, which is fallen, covers jail, and the current of drainage pipeline will not enter gas pipe by suck-back
Road.
