Description
Technical field
The present invention relates to valve technology field, more particularly to a kind of high leakproofness gate valve.
Background technology
Gate valve is one of conventional block valve, the medium for being mainly used to connect or blocking in pipeline, gate valve be applied to pressure,
Temperature and bore scope are very big, and the direction of motion of valve rod is perpendicular to valve seat center line, in being particularly suitable for use in, bigbore pipeline.
According to the shape of valve element point, gate valve is divided into wedge-shaped single disc, wedge-shaped double disc, parallel single disc and parallel double-flashboard, all kinds of wedges
Shape gate valve is domestic using relatively broad gate valve, and flashboard is wedge structure, simple in construction, and cost is low, but sealing effectiveness master
The extruding of flashboard and valve seat is relied on, has operational torque big, moving parts is easily stuck, short life, in-convenience in use waiting intrinsic
The problem of.For example：Chinese patent Authorization Notice No.：CN204267772U, authorized announcement date on April 15th, 2015, discloses one
Kind of gate valve, including brake valve body, gate valve cap, flashboard, pressure cap, screw mandrel and handwheel, gate valve cap by pressure cap tight lock part, central holding portion and
Sealing is constituted, and pressure cap tight lock part is connected with pressure cap, the first mating groove is offered on sealing, pad is placed in the first mating groove
It is interior, auxiliary section is provided with brake valve body, and the second mating groove is provided with auxiliary section, gate valve cap and brake valve body pass through sealing
It is connected, is made up of gate valve cap pressure cap tight lock part, central holding portion and sealing with auxiliary section, first opened up on sealing
The second mating groove is provided with mating groove and auxiliary section, gate valve cap is connected with brake valve body by sealing with auxiliary section.This kind of lock
The sealing of valve is to compress flashboard by valve rod so that the inclined-plane of flashboard and the inclined-plane compression fit of valve seat are sealed, during Gate-valve sealing,
Moment of torsion is very big can just be fully sealed for operation, and when flashboard both sides surface wear is uneven, valve rod also suffers from bending stress, easily leads
Cause stuck phenomenon.
The content of the invention
The present invention is poor in order to solve Gate-valve sealing effect of the prior art, and operation moment of torsion is big, easily stuck when using
It is not enough that there is provided a kind of good sealing effect, small, the anti-jamming high leakproofness gate valve of operation moment of torsion.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of high leakproofness gate valve, including valve body, valve pocket, valve rod, the left and right ends of valve body are respectively equipped with to be connected with valve pocket
Left passage, right passage, valve rod lower end stretched into valve pocket, and the upper end for stating valve pocket is provided with seal receptacle, and the upper end of valve rod is through sealing
Seat, is provided with the upper end on graphite packing, valve rod positioned at graphite plate root and is additionally provided with gland, the left side between the valve rod and seal receptacle
Passage, the inner of right passage are respectively equipped with coaxial left valve seat, right valve seat, and the position between left valve seat, right valve seat is provided with and valve
