Abstract
The present invention relates to have cleaning function high temperature and pressure multichannel shunt reversing valve in a kind of reversal valve, more particularly to one kind.The high temperature and pressure multichannel shunt reversing valve is arranged triple blade constructions, the first blade design poppet head, scrapes extra medium off in closing process；Scraping edge at positive and negative two is designed in second blade design spool primary seal region, primary seal region, and spool strikes off the incrustation generated due to fit clearance or coking during opening and closing；Third blade design designs criss-cross keen edge blowdown slot structure at valve guiding area, valve deck, and dirt discharge groove, which can effectively prevent medium and enter guiding clearance, causes valve stuck phenomenon.While when valve transfer or closing, manually opened flushing valve carries out high temperature and pressure interruption and rinses, and flushing valve inner wall and spool face take away medium, and moving component is stuck caused by preventing because of medium coking.
Description
Technical field
The present invention relates to commutate in a kind of reversal valve, more particularly to a kind of shunt with cleaning function high temperature and pressure multichannel
Valve.
Background technique
It is currently used in the shunt reversing valve of coal slurry medium transmission often because because of moving component caused by coal slurry medium coking
It is stuck.The replacement for causing shunt reversing valve entirety awards enterprise and brings greatly harm and loss.
Summary of the invention
In order to solve the above technical problem, the present invention provides one kind, and there is cleaning function high temperature and pressure multichannel to shunt commutation
Valve.
The technical solution that the present invention takes to achieve the above object are as follows:
One kind having cleaning function high temperature and pressure multichannel shunt reversing valve, which includes main valve body, the main valve
Stand in channel hole and multichannel tap hole are respectively set on body, valve is respectively set between the multichannel tap hole and stand in channel hole
Core control is opened, and the first scraper is arranged in the head of the spool, for scraping extra medium, the seal area of the spool in closing process off
The second scraper is respectively set in two sides, which strikes off the incrustation generated due to fit clearance or coking during opening and closing.
As a further improvement, criss-cross keen edge dirt discharge groove knot is arranged at the valve deck on valve guiding area
Structure, dirt discharge groove, which can effectively prevent medium and enter guiding clearance, causes valve stuck phenomenon.
As a further improvement, high temperature and pressure flushing interface is set on the multichannel tap hole, the high temperature and pressure punching
It washes in interface and valve guiding area and is connected, flushing valve inner wall and spool face.
As a further improvement, flushing valve is arranged in the high temperature and pressure flushing interface.
The triple blade constructions of high temperature and pressure multichannel shunt reversing valve setting of the present invention, the first blade design poppet head,
Scrape extra medium in closing process off；Scraping edge at positive and negative two is designed in second blade design spool primary seal region, primary seal region,
Spool strikes off the incrustation generated due to fit clearance or coking during opening and closing；Third blade design is in valve guide portion
Domain, designs criss-cross keen edge blowdown slot structure at valve deck, and dirt discharge groove, which can effectively prevent medium and enter guiding clearance, to be made
At valve stuck phenomenon.While when valve transfer or closing, manually opened flushing valve carries out high temperature and pressure interruption and rinses, flushing valve
Door inner wall and spool face take away medium, and moving component is stuck caused by preventing because of medium coking.

Specific embodiment
A detailed description is done to a specific embodiment of the invention with reference to the accompanying drawing.
As shown in figures 1 to 6, a kind of to have cleaning function high temperature and pressure multichannel shunt reversing valve, which includes main valve
Stand in channel hole and multichannel tap hole is respectively set on the main valve body 1, in the multichannel tap hole and stand in channel hole in body 1
Between the control of spool 2 be respectively set open, the first scraper 3 is arranged in the head of the spool 2, for scraping extra Jie in closing process off
The second scraper 4 is respectively set in matter, the seal area two sides of the spool 2, which strikes off during opening and closing due between cooperation
The incrustation or coking that gap generates；Criss-cross 6 knot of keen edge dirt discharge groove is set at the valve deck 5 on valve guiding area
Structure, dirt discharge groove 6, which can effectively prevent medium and enter guiding clearance, causes valve stuck phenomenon.
High temperature and pressure flushing interface 7 is set on the multichannel tap hole, and the high temperature and pressure flushing interface 7 is led with valve
It is connected into region, flushing valve inner wall and spool face.Flushing valve 8 is set in the high temperature and pressure flushing interface 7.
Claims (4)
