Abstract
The utility model 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 utility model relates to have self-cleaning function high temperature and pressure multichannel point in a kind of reversal valve, more particularly to one kind
Flow reversal 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-mentioned technical problem, the utility model provides a kind of with self-cleaning function high temperature and pressure multichannel point
Flow reversal valve.
The technical solution that the utility model is taken to achieve the above object are as follows:
One kind having self-cleaning function high temperature and pressure multichannel shunt reversing valve, which includes main valve body, the master
Stand in channel hole and multichannel tap hole are respectively set on valve body, is respectively set between the multichannel tap hole and stand in channel hole
Spool control is opened, and the first scraper is arranged in the head of the spool, for scraping extra medium, the sealing of the spool in closing process off
The second scraper is respectively set in area two sides, which strikes off the incrustation or knot generated due to fit clearance during opening and closing
It is burnt.
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.
Triple blade constructions, the first blade design valve core head is arranged in the utility model high temperature and pressure multichannel shunt reversing valve
Portion scrapes extra medium off in closing process；Second blade design spool primary seal region, primary seal region is designed scrapes at positive and negative two
Sword, spool strike off the incrustation generated due to fit clearance or coking during opening and closing；Third blade design is led in valve
To region, criss-cross keen edge blowdown slot structure is designed at valve deck, dirt discharge groove can effectively prevent medium and enter between guiding
Gap causes valve stuck phenomenon.While when valve transfer or closing, manually opened flushing valve carries out high temperature and pressure interruption and rinses, and rushes
It washes valve inner wall and spool face takes away medium, moving component is stuck caused by preventing because of medium coking.

Specific embodiment
A detailed description is done to specific embodiment of the present utility model with reference to the accompanying drawing.
As shown in figures 1 to 6, a kind of to have self-cleaning function high temperature and pressure multichannel shunt reversing valve, which includes master
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 in valve body 1
The control of spool 2 is respectively set between hole to open, the first scraper 3 is arranged in the head of the spool 2, extra for scraping off in closing process
The second scraper 4 is respectively set in medium, the seal area two sides of the spool 2, which strikes off during opening and closing due to 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.
