Abstract
The invention relates to a reversing valve, in particular to a high-temperature high-pressure multichannel diverting reversing valve with a cleaning function. The high-temperature high-pressure multichannel shunt reversing valve is provided with a triple scraper structure, the first scraper is used for designing the head part of the valve core, and redundant media are scraped in the closing process; the second scraper is provided with a main sealing area of the valve core, the main sealing area is provided with a front scraping blade and a back scraping blade, and scale deposit or coking generated by a fit clearance is scraped in the opening and closing process of the valve core; the third scraper is designed in the valve guide area, and the valve cover is provided with a crisscrossed sharp cutting edge blow-off groove structure, so that the blow-off groove can effectively prevent the phenomenon that a medium enters a guide gap to cause the valve to be blocked. Meanwhile, when the valve is switched or closed, the flushing valve is manually opened to perform high-temperature high-pressure intermittent flushing, and the inner wall of the flushing valve and the surface of the valve core take away media, so that the moving parts are prevented from being blocked due to media coking.
Description
Technical Field
The invention relates to a reversing valve, in particular to a high-temperature high-pressure multichannel diverting reversing valve with a cleaning function.
Background
The existing shunt reversing valve for coal slurry medium transmission is often blocked by moving parts caused by coking of the coal slurry medium. The whole change of the shunt reversing valve is caused, and great harm and loss are brought to enterprises.
Disclosure of Invention
In order to solve the technical problems, the invention provides the high-temperature high-pressure multichannel shunt reversing valve with the cleaning function.
The technical scheme adopted by the invention for realizing the purpose is as follows:
the utility model provides a high temperature high pressure multichannel reposition of redundant personnel switching-over valve with cleaning function, this switching-over valve includes the main valve body, set up into passageway hole and multichannel reposition of redundant personnel hole on the main valve body respectively set up the case control between multichannel reposition of redundant personnel hole and the passageway hole of advancing and open, the head of this case sets up first scraper for scrape unnecessary medium in the closing process, the sealing area both sides of this case set up the second scraper respectively, and scale deposit or the coking that produce because the fit clearance are opened with the in-process to strike off to this case.
As a further improvement, the valve cover on the valve guide area is provided with a crisscrossed sharp-edge drain groove structure, and the drain groove can effectively prevent the blockage of the valve caused by the medium entering the guide gap.
As a further improvement, the multichannel diversion hole is provided with a high-temperature high-pressure flushing interface which is communicated with the valve guide area and used for flushing the inner wall of the valve and the surface of the valve core.
As a further improvement, a flushing valve is arranged on the high-temperature high-pressure flushing interface.
The high-temperature high-pressure multichannel shunt reversing valve is provided with a triple scraper structure, the first scraper is used for designing the head part of the valve core, and redundant media are scraped in the closing process; the second scraper is provided with a main sealing area of the valve core, the main sealing area is provided with a front scraping blade and a back scraping blade, and scale deposit or coking generated by a fit clearance is scraped in the opening and closing process of the valve core; the third scraper is designed in the valve guide area, and the valve cover is provided with a crisscrossed sharp cutting edge blow-off groove structure, so that the blow-off groove can effectively prevent the phenomenon that a medium enters a guide gap to cause the valve to be blocked. Meanwhile, when the valve is switched or closed, the flushing valve is manually opened to perform high-temperature high-pressure intermittent flushing, and the inner wall of the flushing valve and the surface of the valve core take away media, so that the moving parts are prevented from being blocked due to media coking.
