Description
Technical field
The present invention relates to one kind to push closed steam-water separation valve, is related to the device of steam-water separation.It is mainly used in electrolysis
The water treatment fields such as method water process, ballast for cruising water process.
Background technology
Current steam-water separation valve existing on the market is mostly that inner float ball floating is closed, hereinafter referred to as " floating type carbonated drink
Valve ", i.e., ball float is set to float up to seal face to reach the purpose of gas-liquid separation using buoyancy when liquid level raises.Such a floating type
Trap seat is not suitable for gas-liquid environment with pressure, and because it is when liquid level declines, the small inner float ball of light weight density still can be inside and outside
It can not be fallen under draught head effect, form the failure phenomenon that builds the pressure.Moreover, such a floating type trap seat finite volume, gas-permeable channels
Narrow, inner float ball buoyancy is small, and steam-water separation effect is poor.Meanwhile therefore valve often be arranged on discharge duct in, easily there is stress
Deform and block the failure phenomenon of ball float.
The content of the invention
The defects of to overcome prior art, it is an object of the invention to provide a kind of with pressure or pressure change gas-liquid environment
What can be used with continuous-stable down pushes closed steam-water separation valve, and the failure that builds the pressure for solving the closed steam-water separation valve of floating is existing
As.The technical scheme is that：One kind pushes closed steam-water separation valve, including surge tank and mechanism for opening/closing, in the buffering
Mozzle is provided with tank, the joint of the mozzle and surge tank is provided with casing flange；Described mechanism for opening/closing includes close
Capping plate, cover plate connecting rod, floating ball rod, ball float and sleeve pipe, sleeve pipe are welded on the lower surface of casing flange, and in casing flange
Heart hole is corresponding；Cover plate connecting rod is located at the inside of sleeve pipe, is coaxially disposed with sleeve pipe, and the upper end of the cover plate connecting rod passes through casing flange
After centre bore, seal cover board is provided with by nut, lower end and one end of the floating ball rod are hinged, the other end of floating ball rod
Ball float is installed；Close on the casing wall of casing flange centre bore, through hole is provided with；The bottom of outside of sleeve is provided with one
Seat, described floating ball rod are arranged on bearing by what bearing pin rotated；The diameter of described seal cover board is more than casing flange
The diameter of centre bore.
Navigation ring, centre bore of the described cover plate connecting rod through navigation ring are installed in described sleeve pipe.
Described mozzle is connected with surge tank by flange to folder.
It is an advantage of the invention that：
1st, seal cover board is located in the mozzle on the outside of surge tank, pull unit outer side seal lid when the ball float in surge tank is up
Plate pushes the inside and outside cut-off of realization；
2nd, the air pressure inside of surge tank to mechanism for opening/closing provide power, fundamentally prevented common floating type trap seat in height
The failure phenomenon that builds the pressure that can not be fallen under air pressure.
3rd, the movement locus of ball float and seal cover board is accurately controlled using the synergy of navigate ring and sleeve pipe, is evaded
Non-controllable risk under vibrations or swinging condition；
4th, realize that simple and efficient installation is fixed to pressing from both sides by flange, be not take up additional volumes, without to original device or pipe
Transformed on road.
Brief description of the drawings
Fig. 1 is agent structure schematic diagram when ball float of the present invention sinks.
Fig. 2 is agent structure schematic diagram when ball float of the present invention floats.
Embodiment
The invention will now be further described with reference to specific embodiments, advantages of the present invention and feature will be with description and
It is apparent.But these embodiments are only exemplary, do not form any restrictions to the scope of the present invention.People in the art
Member to the details and form of technical solution of the present invention it should be understood that can enter without departing from the spirit and scope of the invention
Row modifications or substitutions, but these modifications and replacement are each fallen within protection scope of the present invention.
Referring to Fig. 1 and Fig. 2, the present invention relates to one kind to push closed steam-water separation valve, including surge tank 1 and headstock gear
Structure, mozzle 2 is provided with the surge tank 1, the joint of the mozzle 2 and surge tank 1 is provided with casing flange 3；It is described
Mechanism for opening/closing include seal cover board 4, cover plate connecting rod 6, floating ball rod 5, ball float 8 and sleeve pipe 7, sleeve pipe 7 is welded on casing flange 3
Lower surface, it is corresponding with the centre bore of casing flange 3；Cover plate connecting rod 6 is located at the inside of sleeve pipe 7, is coaxially disposed with sleeve pipe 7,
After the upper end of the cover plate connecting rod 6 passes through the centre bore of casing flange 3, seal cover board 4, lower end and the ball float are provided with by nut
One end of connecting rod 5 is hinged, and the other end of floating ball rod 5 is provided with ball float 8；Set close on the wall of sleeve pipe 7 of casing flange centre bore
It is equipped with through hole（Arrow represents gas flow direction in figure）；The bottom in the outside of sleeve pipe 7 is provided with a bearing, described ball float connects
Bar 5 is arranged on bearing by what bearing pin rotated；The diameter of described seal cover board 4 is more than the diameter of casing flange centre bore 3,
For when seal cover board declines, the centre bore of casing flange to be covered.
Navigation ring 9, centre bore of the described cover plate connecting rod 6 through navigation ring 9 are installed in described sleeve pipe 7.
Described mozzle 2 is connected with surge tank 1 by flange to folder 10.
The present invention operation principle be：Ball float is separated with sleeve pipe, reaches lifting closing using the leverage of ball float
Effect.When ball float rises, cover plate connecting rod and seal cover board is driven to move down successively by floating ball rod, until seal cover board will cover
The centre bore sealing of pipe flange, realizes the cut-out of passage；When ball float moves down, drive seal cover board move up, realize air-flow according to
It is secondary by carrying out being expelled to mozzle after the through hole of sleeve pipe and the centre bore of casing flange, realize the unlatching of passage.
