Abstract
It may filter that rinsing ball-and-seat is oil gas field technical field of water treatment in a kind of sewage pipe, it overcomes the shortcomings that current technology, it includes drainpipe, palisade net, screen casing, ball-and-seat, pull rod, pull rod pin hole, decontamination orifice, silk plug, decontamination orifice strainer, and the drainpipe bottom end is equipped with screen casing；The ball-and-seat is fixed in drainpipe；The palisade net is mounted on the lower end of drainpipe；The end of the pull rod is passed through by the lower section of palisade net, corresponding with the valve seat of ball-and-seat, and the middle section of pull rod is by being bolted on the tube wall of drainpipe；The stay rod pin is welded on the tube wall of drainpipe；The decontamination orifice is mounted on the middle and upper part of drainpipe.
Description
Technical field
The utility model relates to oil gas field technical field of water treatment, it may filter that flushing is single in especially a kind of sewage pipe
Flow valve.
Background technique
In the process of development, the sewage in water flooding pump station blow-down pit needs to extract out in time by pipeline, water flooding pump station in oil field
Dredge pump in blow-down pit is centrifugal pump of single stage type, and this centrifugal pump inlet need to install ball-and-seat could normal use.Dredge pump exists
The dirt in blow-down pit can be adsorbed onto around ball-and-seat when normal operation, cause after entering because of various sundries, cause ball-and-seat
Poorly sealed, centrifugal pump impeller has sundries to cause pump efficiency low, and sewerage effect is poor, and the service life of centrifugal pump is short.Due to emptying
Pool inner water is deep (deep there are about 2.5M), and currently used method is that centrifugal pump water inlet pipe is needed all to dismantle, from blow-down pit
It is interior that water inlet pipe is taken out, it is installed back again after mixed and disorderly substances in pipe is cleaned out.This conventional method is more time-consuming, Bu Nengji
When solve the problems, such as to cause pump efficiency low because ball-and-seat is poorly sealed, impurity enters centrifugal pump impeller.
Summary of the invention
The utility model aim is to provide that processing and fabricating is simple, may filter that punching in a kind of non-maintaining sewage pipe during use
Ball-and-seat is washed, the shortcomings that it overcomes current technology, the purpose of this utility model is achieved in that it includes drainpipe, grid
Shape net, screen casing, ball-and-seat, pull rod, pull rod pin hole, decontamination orifice, silk plug, decontamination orifice strainer, the drainpipe bottom end are equipped with sieve
Pipe；The ball-and-seat is fixed in drainpipe；The palisade net is mounted on the lower end of drainpipe；The end of the pull rod is by palisade
The lower section of net passes through, corresponding with the valve seat of ball-and-seat, and the middle section of pull rod is by being bolted on the tube wall of drainpipe；The drawing
Lever pin is welded on the tube wall of drainpipe；The decontamination orifice is mounted on the middle and upper part of drainpipe.
The lower end of the pull rod is 1800Half mouthful of shape, there is a cross handle on top.
The decontamination orifice is with radial 600It is connect with drainpipe；There is filter screen in the inside of decontamination orifice, and pipe end of removing contamination installation can
Dismantle silk plug.
The drainpipe is cylinder hollow pipe.
The application method of the utility model is: the drainpipe upper end of the present apparatus is connect with centrifugal pump, only need to before opening pump,
The silk plug of the lower end for pipeline of removing contamination is laid down on ground, decontamination orifice strainer is taken out and removes dirt, then installs decontamination orifice filter again
Net and silk plug；Raising rod opens ball-and-seat, opens backwater valve, rinses ball-and-seat a few minutes using the return water for having pressure,
After ball-and-seat in drainpipe is rinsed well, pull rod is put down, closes ball-and-seat, the water in return piping will fill pump chamber and row
Then water pipe starts centrifugal pump, by the water in cesspool by extracting out after decontamination orifice filter screen.
The meaning of the utility model is: Pump Station in Oil Field, can by may filter that flushing ball-and-seat in present apparatus sewage pipe
To efficiently solve in sewage pipe ball-and-seat because sundries leads to poorly sealed, the phenomenon of upper water difference；The present apparatus reduces impurity pair
The erosion of centrifugal pump impeller and sealing device, improves the pump efficiency of centrifugal pump, also extends the service life of dredge pump；The present apparatus
Processing and fabricating is simple, non-maintaining during use.
Detailed description of the invention
Fig. 1 is that may filter that the structural schematic diagram for rinsing ball-and-seat in a kind of sewage pipe, 1, drainpipe 2, palisade net in figure
3, screen casing 4, ball-and-seat 5, pull rod 6, pull rod pin hole 7, decontamination orifice 8, silk plug 9, decontamination orifice strainer.
Specific embodiment
Embodiment 1, the utility model include drainpipe 1, palisade net 2, screen casing 3, ball-and-seat 4, pull rod 5, pull rod pin hole 6,
Decontamination orifice 7, silk plug 8, decontamination orifice strainer 9,1 bottom end of drainpipe are equipped with screen casing 3；The ball-and-seat 4 is fixed on drainpipe
It is interior；The palisade net 2 is mounted on the lower end of drainpipe 1；The end of the pull rod 5 is passed through by the lower section of palisade net 2, with ball-and-seat
4 valve seat is corresponding, and the middle section of pull rod 5 is by being bolted on the tube wall of drainpipe 1；The stay rod pin 6 is welded on drainpipe 1
Tube wall on；The decontamination orifice 7 is mounted on the middle and upper part of drainpipe 1.
Embodiment 2, the pull rod 5 lower end be 1800Half mouthful of shape, there is a cross handle on top.
Embodiment 3, the decontamination orifice 7 are with radial 600It is connect with drainpipe；There is filter screen 9 in the inside of decontamination orifice 7, removes contamination
7 end of pipe is installed by detachable silk plug 8.
Embodiment 4, the drainpipe 1 are cylinder hollow pipe.
