The invention discloses a plug slurry valve which comprises a valve body (8), a valve cover (6) and a valve core; wherein the valve core is a half-plug double eccentric valve core (9), the half-plug double eccentric valve core (9) is rotatablely arranged in the valve cover (6) and the valve body (8) through an eccentric upper half shaft (5) and an eccentric lower half shaft (10), and the eccentric upper half shaft (5) is connected with a rotary opening device. The rotary opening device is arranged on a worm wheel drive box (2) on the valve body (8), the eccentric upper half shaft (5) is drivingly connected with a worm wheel shaft (3) of the worm wheel drive box (2), and a worm shaft of the worm wheel drive box (2) is connected with a hand wheel (1). The invention can be vertically or horizontally arranged. Therefore, the invention has the advantages of the small occupancy space and the comparatively convenient operation and maintenance.
Description
technical field [0001] The invention relates to a slurry valve, in particular to a cock type slurry valve. technical background [0002] The existing slurry valve structure is gate type, and its height is about 4-5 times of its nominal diameter; when the valve diameter is large, its height dimension is very large, occupying a large installation space, and only For vertical installation, large-diameter valves generally need to be equipped with a dedicated operating platform, which is not only costly, but also difficult to operate, install and maintain. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cock type slurry valve which can be installed vertically or horizontally, takes up little space and is easy to operate and maintain. [0004] In order to solve the above technical problems, the cock type slurry valve provided by the present invention includes a valve body, a valve cover and a spool, the spool is a h...
