Abstract
A single-port negative pressure automatic drainage device of a pumping-releasing gas pipeline is molded by means of the injection of polyvinyl chloride (PVC) materials and composed of a negative pressure automatic drainage box and a water inlet balance device which is formed by a balance pipe and a water inlet pipe. One end of the water inlet pipe is communicated with the negative pressure automatic drainage box, the other end of the water inlet pipe is connected with a pumping-releasing gas pipeline, and the upper end of the negative pressure automatic drainage box is communicated with the water inlet pipe through the balance pipe. Due to the fact that the single-port negative pressure automatic drainage device of the pumping-releasing gas pipeline is molded by means of the injection of the polyvinyl chloride (PVC) materials, thus the single-port negative pressure automatic drainage device is small in size and light in weight, the installation structure of a drainage device is improved, the efficiency is improved, and the failure rate is reduced.
Description
Technical field
The utility model belongs to tailrace, specifically be a kind of automatic tailrace of pipeline negative pressure that draws out methane of single interface.
Background technology
At present, the colliery highly gassy mine has all been installed gas pumping station, and in use the gas discharge in mine pipeline can accumulate big water gaging and cinder, causes pipeline blockage, has reduced gas drainage under suction efficient.So coal mine gas negative pressure extraction pipeline has been installed a large amount of automatic tailraces of gas drainage under suction pipeline.
But the automatic tailrace of gas drainage under suction pipeline of coal mine gas negative pressure extraction pipeline installation at present has following shortcoming: 1, all made by metal material, volume is big, and cost is high, and owing to reasons such as metallic material corrosions, fault rate is high, and the life-span is short.2, all be to be connected with the gas drainage under suction pipeline by two interfaces of water inlet pipe and balance pipe, installation cost is high, and installation effectiveness is low, uses inconvenience, poor air-tightness.
The utility model content
The utility model technical problem to be solved provides a kind of automatic tailrace of pipeline negative pressure that draws out methane of single interface, and by the injection mo(u)lding of PVC material, volume is little, in light weight, improves the tailrace mounting structure, has improved efficient, has reduced fault rate.
The utility model is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: a kind of automatic tailrace of pipeline negative pressure that draws out methane of single interface; By the injection mo(u)lding of PVC material; Be made up of automatic delivery box of negative pressure and water inlet bascule, described water inlet bascule is made up of balance pipe and water inlet pipe, and an end of water inlet pipe is connected with the automatic delivery box of negative pressure; The other end is connected with the gas drainage under suction pipeline, and the upper end of the automatic delivery box of negative pressure is communicated with water inlet pipe through balance pipe.
The described balance pipe of the utility model is crooked and is provided with.
The described balance pipe of the utility model is communicated with the place with water inlet pipe height is lower than the height at balance pipe turning.
The beneficial effect of the utility model is: the utility model adopts plastic material, has the flame-retardant and anti-static function, and is simple in structure; Have only an interface to be connected with the gas drainage under suction pipeline, just solved balance and discharged water problem, volume is little, in light weight; Simple installation, fault rate is low, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, the automatic delivery box of negative pressure, 2, balance pipe, 201, the turning, 3, water inlet pipe, 4, the water inlet bascule.
The specific embodiment
As shown in the figure; A kind of automatic tailrace of pipeline negative pressure that draws out methane of single interface; Be made up of automatic delivery box 1 of negative pressure and water inlet bascule 4, described water inlet bascule 4 is made up of balance pipe 2 and adjutage 3, and an end of adjutage 3 is connected with the automatic delivery box 1 of negative pressure; The other end is connected with the gas drainage under suction pipeline, and the upper end of the automatic delivery box 1 of negative pressure is connected with water inlet pipe 3 through balance pipe 2.
Described balance pipe 2 is crooked and is provided with.
Described balance pipe 2 is communicated with the place with adjutage 3 height is lower than the height at the turning 201 of balance pipe 2, and anti-sealing gets into balance pipe.One end of balance pipe is connected with the automatic tailrace of negative pressure, and the other end is connected with water inlet pipe.
Claims (3)
