SUMMERY OF THE UTILITY MODEL
In order to improve the problem, the utility model provides a sleeve evacuation stop valve.
The following technical scheme is adopted: the valve comprises a valve body and a valve rod, wherein a medium input channel and a medium output channel are respectively arranged on two sides of the valve body, a cavity is formed in the middle of the valve body, the medium input channel is connected with the lower end face of the cavity, the medium output channel is connected with the side end face of the cavity, a sealing seat is arranged at the connecting end of the cavity and the medium input channel, a valve clack is arranged on the sealing seat, a valve cover is arranged at the upper end of the valve body, the outer wall of the valve cover is connected with a support, the other end of the support is connected with a valve rod nut, a filler is arranged in the inner cavity of the valve cover, a filler pressing plate is fixed at the upper end of the filler, the valve rod penetrates through the filler pressing plate and the valve cover to be connected with the valve clack, and a sleeve sleeved outside the valve clack is arranged between a sealing ring below the filler and the sealing seat.
This design can play the double-deck sealed between valve rod and the packing through setting up the sleeve, also plays the effect of protection simultaneously.
Furthermore, the sleeve outer wall is equipped with a plurality of through-holes, guarantees that the medium can normally circulate when playing the support.
Furthermore, the other end of the valve rod penetrates through a valve rod nut to be connected with a hand wheel, so that the opening degree of the valve can be controlled conveniently.
Compared with the prior art, the beneficial effects of the utility model are that:
the opening of the valve is controlled by the up-and-down movement of the valve clack, and when the valve is closed, medium enters the valve from the upper part of the valve clack, pressure is applied to the valve clack to force the sealing surface not to leak. The sleeve is added to play a role in double-layer sealing effect between the valve rod and the filler and also has a protection effect. The valve is easy to leak and is used for working conditions with higher requirements on field sealing performance.
The present invention will be explained in detail with reference to the drawings and specific embodiments.
