Abstract

The invention discloses a negative pressure deslagging dredging core pipe valve, which is one of self-operated control valves of conventional core pipe valve plates in an original core pipe valve parent series. A valve core pipe is a fixed piece which is perpendicular to the ground surface, and coaxially penetrates through a sleeve I of a valve body, an inner cavity of the valve body and a sleeveII of the valve body from top to bottom; an axial partition layer is arranged in the middle of the valve core pipe; at least one radial circulating hole of each of an input section and an output section is formed in each of the two sides of the axial direction of the partition layer; an upper axial annular valve core and a lower axial annular valve core which surround the partition layer respectively form sealing pairs with annular valve seats at a throat part of each of the sleeve I and the sleeve II; the input section and the sleeve I as well as the output section and the sleeve II are in axial hole type fit, and at least one combination part is arranged in a sealed manner; a driving element which drives the valve body to travel upwards in the axial direction is arranged out of the valvebody; and under the action of liquid gravity and the driving element, the valve body moves reciprocally in the axial direction relative to the valve core pipe so as to realize discharging and closingof sludge and accumulated water. The negative pressure deslagging dredging core pipe valve is simple in structure, small in size, high in cost performance, large in discharging aperture and long in service life, and is flexible and reliable.

Description

technical field [0001] The negative pressure slagging and draining core tube valve of the present invention belongs to the field of valves, and is one of the self-operated control valves of the conventional core tube valve plate in the core tube valve mother series invented by myself; the negative pressure slagging and draining core tube valve It will replace the negative pressure slag discharge water release device, especially the mine negative pressure slag discharge water discharge device. Background technique [0002] There is a large amount of water and sediment in the coal mine gas pipe drainage system, which often causes pipeline blockage, poor drainage, increases the negative pressure of the system, increases the torque of the drainage motor, and greatly reduces the drainage efficiency, which makes the safety Production is seriously threatened. It is suitable for negative pressure automatic slag discharge and water discharge device for the main pipe, main pipe and b...
