Background technology
Gate valve refers to the valve that vertical direction of the flashboard along path center line is moved.Gate valve is mainly cut off in pipeline
With.Gate valve has the advantage that：1. fluid resistance is small.2. external force needed for being opened and closed is smaller.3. medium flow to it is unrestricted. ④
During standard-sized sheet, sealing surface is smaller than stop valve by the erosion of working media.5. the bodily form is fairly simple, and casting manufacturability is preferable.Therefore lock
Valve has a wide range of applications purposes.
But in the prior art, gate valve leaves problems with：
（1）Valve rod can produce electrostatic in driving flashboard lifting process between flashboard and valve seat, and inflammable for what is transported
During explosive medium, flashboard, which opens and closes the electrostatic produced, will bring potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the shortcoming and defect that prior art is present, and provide a kind of structure design
Rationally, the sylphon seal gate valve with function of eliminating static with electrostatic remove function.
To achieve the above object, the technical solution of the utility model is to include valve body, flashboard, bonnet, valve rod and valve rod liter
Drive mechanism is dropped, runner is provided with described valve body, the runner is in the both-side opening of valve body, and the valve body is relative to stream
Valve seat is provided with road, described flashboard lifting is actively arranged in valve seat, and linkage is fixed in the upper end of the flashboard with valve rod
Coordinate, the valve rod outer sheath in bonnet is provided with bellows, upper end and the sealing welding at the top of bonnet inwall, ripple of the bellows
Line pipe lower end and stem bottom sealing welding, it is characterised in that：The upper end of described bonnet also flange is fixedly connected with filler set,
Packing cavity is set between described filler set and valve rod, filler is provided with the packing cavity, and the top of filler set is fixedly connected
There is gland, inner set of the gland is crimped on hold-down grid above filler, and described filler set is conductive filler
Set, described valve rod is conductive valve rod, and counterbore is provided with the inside side walls of described conductive filler set, in the counterbore from it is interior to
Outer to be disposed with the power spring and conductive steel ball for contacting with each other and being linked, the outer end of described conductive steel ball is led with valve rod
Electrical contact coordinates.
Further set is that described valve rod lift drive mechanism includes the handwheel coordinated with the coaxial joint rotation of valve rod
And valve stem nut, the valve stem nut is oriented to be connected outside cooperation, described valve stem nut with threaded stem is fixedly installed nut pressure
Fuel feeding valve is provided with lid, the nut gland, one section of shoe cream room, described note are provided between described valve stem nut and valve rod
The interior oil-out of fuel tap is connected with the shoe cream room.
The utility model has the advantages that being that the electrostatic produced in flashboard lifting process export in time can be prevented into electrostatic
Accumulation, improves security, in addition, setting shoe cream room between valve stem nut and valve rod, and carries out oiling by fuel feeding valve, ensures
Rotation lubricity between valve rod and valve stem nut, is easy to manipulation.
The utility model is described further with reference to specification drawings and specific embodiments.
