Abstract
The utility model provides a hard sealing plug valve with a guiding mechanism, which belongs to the field of valves. The hard sealing plug valve with the guiding mechanism comprises the guiding mechanism fixed in a holding cavity, wherein the guiding mechanism comprises an upper guiding disc and a lower guiding disc. The hard sealing plug valve with the guiding mechanism solves the technical problems that a plug body of a conventional plug valve is easy to deviate to cause overlarge torque and even jamming and the like when the pressure of a medium is overlarge; when the pressure of the medium is overlarge, under the condition that the plug body is extruded, as two ends of the plug body are limited by the guiding discs, the position of the plug body cannot deflect; and furthermore, the plug body can transfer the pressure of the medium onto a valve body by the guiding discs at the upper end and the lower end, thereby avoiding the jamming at the joint of a valve rod and a valve cap, reducing the operating torque of the plug valve when the pressure of the medium is overlarge, further avoiding of damaging the valve synchronously, and prolonging the service life of the hard sealing plug valve.
