Abstract
The invention provides a full-channel self-sealing butterfly type spherical valve which comprises a valve body, an upper shaft, a lower shaft, a butterfly wing valve element, a wing frame and a floating sealing pair. The butterfly wing valve element is arranged in a rotary shell body inside the valve body. The wing frame is used for fixing the butterfly wing valve element. When the valve is opened at 90 degrees, the middle of the spherical wing frame and the middle of the butterfly wing valve element are attached to the inner side of the valve body, the two ends of the butterfly wing valve element are attached to the wall of a pipe, a fully-communicated channel is formed through the side wall of a pipe space, so that media flow without being blocked, the head loss coefficient of flow resistance is lower than 0.035, and the energy-saving benefits are good. When the valve is closed, on one hand, large pressure is exerted on the butterfly wing valve element by fluid, so that the floating sealing pair is tightly pressed by the butterfly wing valve element and self sealing is achieved; on the other hand, due to the compensation function of gradually eccentric rotation of the floating sealing pair and butterfly wings, the floating sealing pair is automatically pushed to tightly press the butterfly wing valve element, the abrasion of the butterfly wing valve element or a sealing ring is compensated, the sealing problems caused by other reasons are solved, and the service life of the full-channel self-sealing butterfly type spherical valve is prolonged.
Description
Technical field
The present invention relates to valve field, be specifically related to a kind of full tunnel selfsealings butterfly spherical valve.
Background technique
Ball valve is mainly used to make cut-out, distributes and change medium in pipeline flow direction, it only need to just can be closed tightly with the operation of 90-degree rotation and very little moment of rotation.Its compact structure is simple, sealing is reliable, easy to maintenance, sealing surface and the sphere closed state of being everlasting, be difficult for by the medium erosion, easy operating and maintenance, be applicable to the general work media such as water, solvent, acid and rock gas, but also be applicable to the abominable medium of operating conditions, as oxygen, hydrogen peroxide, methane and ethene etc., be widely used in every profession and trade, but its machining accuracy is high, involves great expense, be difficult in high temperature using, as impurity is arranged in pipeline, easily by impurity, stopped up, cause valve to open.

Further, described wing frame 4 is an arc plate-shaped member, and its upper end is connected with described upper axle 6, and lower end is connected with described lower shaft 8, can freely rotate in valve body; The midpoint of described wing frame 4 projection one sides is provided with round boss 41; It is porose 31 that the center of described butterfly wing spool 3 arranges, and butterfly wing spool coordinates and is arranged on wing frame 4 with described round boss 41 by described hole 31, and with described wing frame, is fastenedly connected, and facilitates valve to safeguard.
Further, the outer surface of described butterfly wing spool 3 is the part of sphere or the part of conical surface.
Further, the outer of described butterfly wing spool 3 is provided with ring platform 32, and described ring platform 32 coordinates and seals or open the MEDIA FLOW circulation passage with described valve seat 2.
Further, described ring platform 32 outers are provided with sphere chamfering 33, and described sealing pair 5 is with described sphere chamfering 33 fitted seal or open the MEDIA FLOW circulation passage.
Further, described butterfly wing spool 3 is the part of hollow ball.
Further, the shaft axis of described upper axle 6 and described lower shaft 8 is on same straight line 03, and described straight line 03 on the maximum longitudinal section 04 of the valve interior surface perpendicular to valve interior surface transversal line 02, and deviates from the valve interior surface centre of sphere 01.
