Problems solved by technology
When the driving arm rotates clockwise, the pipe cleaning disc valve is opened and is in the open state. At this time, the wear-resistant pigging guide tube and the pipeline are completely aligned to form a complete full-bore pipeline. However, the wear-resistant pigging guide in this patent The guide tube of the grinding pipe is not tightly sealed, and the medium within the α angle, such as powder medium, will leak into the valve body cavity, resulting in blockage and jamming

Embodiment 1
[0041] like Figure 2-Figure 4 As shown, the present invention provides an anti-clogging and anti-jamming disc valve, which is a completely sealed anti-clogging and anti-jamming disc valve, which will not cause wear and tear on the wear-resistant pigging guide tube During the rotation of the valve disc, the fluid (powder, particles) enters the valve cavity, causing blockage, and the valve body 1 and left body 2 are worn out, causing the valve to be stuck and unable to operate. The anti-clogging and anti-jamming disc valve structure is mainly composed of valve body 1, left body 2, valve disc 3, sealing valve seat 23, valve stem 4, driving arm 5, valve stem packing 6, butterfly spring 7, valve disc Spring 8, spring 9 for the valve stem, bolt / nut 10, screw plug 11, powder-proof sealing cover 16, powder-proof gasket 15, wear-resistant pigging guide tube 12, wear-resistant support rail, the valve disc 3 , valve stem 4, powder-proof sealing cover 16, powder-proof gasket 15, wear-re...

The invention provides an anti-blocking anti-jamming disk valve. A valve body and a left body are respectively provided with a wear-resistant supporting track; two end surfaces of a wear-resistant pigging guide shell are respectively provided with a seal valve seat; an anti-powder seal cover is arranged outside each seal valve seat; an anti-powder gasket is arranged inside each anti-powder seal cover; and a pretightening component is arranged between a valve stem and each anti-powder seal cover. Dielectric powder passes through the wear-resistant pigging guide shell; in the rotation process, the dielectric powder can not enter the valve cavity due to the anti-powder seal covers; the anti-powder gasket and pretightening component are arranged between the anti-powder seal cover and valve stem; since the anti-powder gasket forms an interference fit, the full sealing can be sufficiently ensured; and even if the surface of the anti-powder seal cover is abraded, the pretightening component can perform the further supplementing function, so that the anti-powder seal cover and wear-resistant supporting track can be matched in a gapless mode, thereby preventing the powder from entering the valve cavity, avoiding the occurrence of blocking, jamming and other conditions to the valve, and prolonging the service life.
Description
technical field [0001] The invention belongs to the technical field of valve manufacturing, in particular, the invention relates to an anti-clogging and anti-jamming disc valve. Background technique [0002] In the current existing technology, the energy-clearing pipeline disc valve used on the polysilicon used in the new energy industry, the coal-to-oil in the coal chemical industry, the coal powder transportation in the power plant, the pulp transportation in the paper industry, and the mud transportation pipeline in the cement plant is due to The wear-resistant pigging guide tube is easy to wear and the fluid (powder, particles) will easily enter the valve cavity during the rotation of the valve disc to cause blockage, and the valve body and left body will be worn and cause the valve to be stuck or even stuck. [0003] The utility model patent No. CN201120277577.9 discloses a disc valve capable of clearing pipelines, which mainly consists of a valve body, a left body, a v...
