Description
Technical field
This utility model is related to a kind of gate valve, more particularly to a kind of parallel double-flashboard gate valve.
Background technology
Valve is in fluid system, for controlling the device of the direction of fluid, pressure, flow, is to make pipe arrangement and equipment
Interior medium (liquid, gas, powder) flows or stops and can control the device of its flow.Valve has many types, such as gate valve,
Choke valve, ball valve, butterfly valve, diaphragm valve, plunger valve, plug valve etc..Gate valve is an opening and closing element flashboard, the direction of motion of flashboard with
Flow direction is perpendicular, and gate valve can only make standard-sized sheet and fully closed.Gate valve flow resistance is little, is not likely to produce water hammer, simple structure,
Both sides are symmetrical, and the scope of application is very wide.But, in gate valve opening-closing process, sealing part abrasion is serious, and most gate valves are all because sealing member is damaged
Bad, leakage, finally cannot just be continuing with；This serious curtailment service life of gate valve, limits the application of gate valve.
Content of the invention
This utility model provides a kind of parallel double-flashboard gate valve for solving above-mentioned technical problem.
Technical solution adopted in the utility model is：A kind of parallel double-flashboard gate valve, including valve body, valve gap, handwheel, valve
Bar and two pieces of parallel flashboards, are provided with the connecting rod that two middle parts are hinged into X-shaped between two pieces of flashboards；Under the connecting rod
End is hinged on the flashboard, and upper end is hinged on slide block；The flashboard is provided with the slideway for being available for the slide block to slide up and down；
Being provided between two connecting rods can be along the cross bar of the link motion；The valve rod is fixedly connected on above the cross bar；Institute
State in valve body limiting plate is provided with the flashboard relative position.Handwheel is rotated, valve rod is moved down, driven under cross bar, connecting rod, flashboard
Move；Flashboard lower end becomes after being against limiting plate and cannot continue to move down, and valve rod continues to drive cross bar to move down, and connecting rod lower end is hinged on flashboard
On cannot continue to move down, hence in so that slide block along slideway glide, therefore two rod hinge connections into X-shaped shape become flat (i.e. connecting rod with
Horizontal plane angle diminishes), connecting rod promotes two parallel gate plates to two end motions, compresses valve seat, realizes valve closing.This utility model
Parallel double-flashboard gate valve in opening-closing process flashboard and valve seat without friction, significantly reduce the abrasion of sealing member, extend valve
Service life.
As further improvement, the connecting rod be provided with section in major arc shape, the guide groove that axially extends；The guide groove
Closed at both ends；The cross bar two ends are provided with the spheroid that can be moved in the guide groove.Spheroid is moved in guide groove, end seal on guide groove
Close in order in gate opening spheroid move to can drive behind guide groove upper end flashboard rise；Guide groove lower end closed is in order to lock
Plate level position do maximum spacing, in order to avoid with valve seat apart from too small and damage sealing member by pressure.
Used as further improvement, the spheroid is provided with a ring groove along guide groove place plane；The cross bar two ends
It is enclosed within the annular groove by an annulus respectively and is connected with the spheroid.Spheroid is rolled in guide groove, reduces friction.
Used as further improvement, the guide groove lower end is provided with rubber blanket.So that flashboard level maximum spacing place slightly
Surplus, to control sealing member pressing degree.
This utility model has the advantages and positive effects of：As this utility model is using as above technical scheme, rotate
Handwheel, valve rod are moved down, and drive cross bar, connecting rod, flashboard to move down；Flashboard lower end becomes after being against limiting plate and cannot continue to move down, valve rod
Continue to drive cross bar to move down, connecting rod lower end is hinged on flashboard cannot continue to move down, hence in so that slide block glides along slideway, therefore
Two rod hinge connections into X-shaped shape become flat (i.e. connecting rod with horizontal plane angle diminish), connecting rod promotes two parallel gate plates to transport to two ends
Dynamic, valve seat is compressed, valve closing is realized.Parallel double-flashboard gate valve of the present utility model in opening-closing process flashboard and valve seat without rubbing
Wipe, significantly reduce the abrasion of sealing member, extend valve service life.
Except this utility model described above solve technical problem, constitute technical scheme technical characteristic and by
Outside the advantage brought by the technical characteristic of these technical schemes, other technologies problem that this utility model can be solved, technology
The advantage brought by the other technical characteristics included in scheme and these technical characteristics, makees into one hereinafter in conjunction with accompanying drawing
Step detailed description.
