Description

A kind of special drainage arrangement suitable for big water content device in Gas conveyance conduit
Technical field
The utility model belongs to mine gas pump drainage technical field, and in particular to one kind is applied to that water content is big, operation pressure The drainage arrangement of the buried conveyance conduit of the low device in Gas of power.
Background technology
Fig. 2 is the drainage arrangement that tradition uses, and is used on the few natural gas line of water content, using good but traditional Drainage arrangement apply and a series of problems occur when in gas feed channel:
1st, when device in Gas manifold pressure is less than 20kPa, the water in pipe can not discharge water by the pressure of gas in itself Ground.
2nd, the water storage cylinder body volume of traditional drainage arrangement is small, and pipeline internal water accumulation is serious.
3rd, the drainpipe of traditional drainage arrangement is arranged on pipeline center, influences pipeline and leads to ball operation.
4th, traditional jettison gear is directly installed on pipeline, is easily deformed out by the extruding of pipeline dilation matrices Split, cause gas leakage.
The content of the invention
The utility model is applied when in gas feed channel to solve conventional discharge device, and its drainage effect is by gas tube Interior pressure influence is big, easy ponding, yielding problems of crack, and then provides and a kind of be applied to that water content is big, operation pressure The special drainage arrangement of the low device in Gas conveyance conduit of power.
The utility model adopts the following technical scheme that:
A kind of special drainage arrangement suitable for big water content device in Gas conveyance conduit, including water storage cavity, the water storage cavity It is placed on the outside of device in Gas conveyance conduit, water storage cavity front end is connected by aqueduct with device in Gas conveyance conduit;The water storage cavity Drainpipe and muffler are connected with the top of tail end, the tail end bottom of water storage cavity is connected with blow-off pipe, drainpipe, muffler and blowdown Draining tube valve, return-air tube valve and blowdown tube valve are correspondingly provided with pipe;The drainpipe inserts from water storage cavity plan vertical Water storage cavity bottom.
The bottom of the drainpipe is oblique discharge outlet, oblique to be designed with beneficial to hydraulically-formed, beneficial to draining, meanwhile, tiltedly Mouth is less prone to the situation of blocking.
The water storage cavity is arranged at the position beyond 1 meter of device in Gas conveyance conduit, first, ensureing installation connection enough Space, second, reducing the influence that drainage arrangement conveys main pipeline to device in Gas.
The muffler is connected with drainpipe, and the pipeline that is connected is provided with total valve, real using main valve gate control pressure of return water Existing draining.
The utility model has the advantages that:
1st, muffler is additionally arranged, the device in Gas left in last time draining can be pressed back into water storage cavity by muffler It is interior, discharge device in Gas during discharging water can be avoided to cause danger;
2nd, avoid jettison gear to be directly installed on pipeline, the dress that discharges water need to be removed by not only solving when conventional pipeline leads to ball The problem of putting, and jettison gear can be avoided to deform and damage in the presence of pipeline extension stress;
3rd, the blow-off pipe of water storage cavity bottom, mixed and disorderly substances in pipe can be periodically excluded, avoids mixed and disorderly substances in pipe from blocking the drainpipe mouth of pipe;
4th, the water storage cavity of Large Copacity, substantial amounts of condensate in pipe can be accommodated, not only avoids accumulation of condensed water in pipeline, And solve the problems, such as that track walker's number that discharges water daily is frequent;
5th, using bigbore aqueduct, suitable for the big gas pipeline of gas water content.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of existing drainage arrangement;
In figure:1- threeways I, 2- aqueducts, 3- threeways II, 4- water storage cavities, 5- drainpipes, 6- mufflers, 7- draining pipe valves Door, 8- return-airs tube valve, 9- total valves, 10- blow-off pipes, 11- blowdowns tube valve, 12- device in Gas conveyance conduits.
Embodiment
With reference to accompanying drawing, specific embodiment of the present utility model is described further:
Special drainage arrangement suitable for big water content device in Gas conveyance conduit as shown in Figure 1, including connection device in Gas The positive threeway 1 of pipeline, aqueduct 2, the threeway 3 for connecting water storage cavity, water storage cavity 4, drainpipe 5, muffler 6, draining tube valve 7, Return-air tube valve 8, drainpipe total valve 9, blow-off pipe 10, blowdown tube valve 11.The left and right ends connection gas tracheae of positive threeway 1 Road, the positive lower end of threeway 1 connect aqueduct 2, and aqueduct 2 is connected to the water storage cavity 4 of Large Copacity by threeway 3, and drainpipe 5 is from water storage The bottom of water storage cavity 4 is inserted on the top of chamber 4, and discharge outlet is designed using oblique mouth, and installation muffler 6 connects with drainpipe 5 on water storage cavity 5 Connect, the bottom installation blow-off pipe 10 of water storage cavity 4.
Before the drainage arrangement is typically mounted at the climbing of gas feed channel, the water condensed out in conduit running passes through aqueduct 2 Flow into water storage cavity 4, when carrying out draining, first open draining tube valve 7 and backwater tube valve 8, total valve 9, which is in, closes shape State, the device in Gas in drainpipe 5 is pushed back to water storage cavity 4 by muffler 6 under differential pressure action in pipe, then opened again Draining main valve 9 carries out draining.
