Abstract

The utility model discloses a gate valve which comprises a valve body, wherein a valve cover is installed at the upper end of the valve body; a valve rod is rotationally installed in the valve cover; a valve plate is fixedly installed at the lower end of the valve rod and located in the valve body; an upper sealing seat is fixedly installed between the valve rod and the valve cover; a press plate is fixedly installed at the upper end of the valve cover; a filler is added between the upper sealing seat and the press plate; and the valve cover is fixedly connected with the press plate. The gate valve disclosed by the utility model is good in sealing condition, capable of saving loss, and convenient to operate.

Description

Gate valve
Technical field
The utility model relates to a kind of gate valve.
Background technique
In pipeline, work the gate valve kind of blocking medium a lot, hard seal eccentric gate valve and soft seal constant-current type gate valve are arranged, the sealing of hard sealed constant-current type gate valve is metal to metal, phase-contact surface meeting phase mutual friction after long-time the use, make and be sealed with certain leakage, the sealing of soft seal constant-current type gate valve is metal pair rubber, phase-contact surface can the phase mutual friction after long-time the use, sealing can reach zero leakage, graphite circle in the prior art valve does not have angle quite and packing ring, can make graphite extrusion-deformation cause blocking the valve seat motion.
The model utility content
The utility model provide a kind of air-proof condition good, play and save loss, easy to operate gate valve.
The utility model technical solution problem provides following scheme:
A kind of gate valve, comprise valve body, it is characterized in that: described valve body upper end is equipped with valve gap, be rotatablely equipped with valve rod in the described valve gap, the lower end of described valve rod is installed with valve plate and is positioned at valve body, is installed with upper seal support between described valve rod and the valve gap, described valve gap upper end fixed installation pressing plate, add filler between described upper seal support and the pressing plate, be fixedly connected with between described valve gap and the pressing plate.
The upper end of described valve rod is passed valve gap and handwheel is installed.
The utility model is filled filler at the joint of valve gap and valve body fixed installation upper sealing valve seat between described upper sealing valve seat and the pressing plate, plays the effect that compresses valve rod and valve gap, thereby reaches good sealing effect.
