Embodiment Construction

[0016] The specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as Figure 1-6 As shown, a high-temperature, high-pressure multi-channel diverter reversing valve with a cleaning function, the reversing valve includes a main valve body 1, and the main valve body 1 is respectively provided with an inlet channel hole and a multi-channel diverter hole, and in the multi-channel A valve core 2 is set between the distribution hole and the inlet channel hole to control the opening. The head of the valve core 2 is equipped with a first scraper 3, which is used to scrape off the excess medium during the closing process. The two sides of the sealing area of ​​the valve core 2 are respectively set The second scraper 4 scrapes off the fouling or coking caused by the fit gap during the opening and closing of the valve core 2; the valve cover 5 on the valve guide area is provided with a structure of criss-...

Abstract

The invention relates to a reversing valve, in particular to a high temperature and high pressure multichannel flow dividing reversing valve with a cleaning function. The high temperature and high pressure multichannel flow dividing reversing valve with the cleaning function is provided with three scraping knife structures, wherein a first scraping knife is arranged on the head of a valve core andis used for scratching out redundant media in a closing process; two second scraping knives are arranged at the main sealing area of the valve core, are a front scraping knife and a back scraping knife and are used for scraping out scale or coke generated due to fit clearances in the opening and closing process of the valve core; a third scraping knife is arranged at a guide area of the valve; sharp cutting edge pollution discharge groove structures are arranged on a valve cover in a crisscross pattern; and the pollution discharge grooves can effectively prevent the media from entering guiding clearance to cause the jamming of the valve. When the valve is switched or closed, a flush valve is manually opened for high temperature and high pressure interrupted washing of the inner wall of the valve and the surface of the valve core, so that the media are taken away, and the jamming of a moving part caused by medium coking is avoided.

Description

technical field [0001] The invention relates to a reversing valve, in particular to a high-temperature, high-pressure, multi-channel shunting reversing valve with a cleaning function. Background technique [0002] In the existing diverter reversing valve used for coal slurry medium transmission, the moving parts are often stuck due to coking of the coal slurry medium. Cause the replacement of the diverter reversing valve as a whole, bring great harm and loss to the enterprise. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a high-temperature, high-pressure, multi-channel diverter reversing valve with a cleaning function. [0004] The technical scheme that the present invention takes for realizing the above object is: [0005] A high-temperature, high-pressure multi-channel diverter reversing valve with a cleaning function, the reversing valve includes a main valve body, and the main valve body i...
