Description
Technical field
The invention belongs to valve field, more particularly to a kind of pneumatic cast steel gate valve.
Background technology
Valve is the control unit in fluid delivery system, with cut-off, regulation, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.Gate valve is a kind of conventional valve, gate valve is internally provided with an opening and closing element flashboard, the direction of motion of flashboard is perpendicular with flow direction, gate valve makees standard-sized sheet and fully closed, can be widely used for being used as regulation and cut-off equipment on the fluid lines such as running water, sewage, building, oil, chemical industry, food, medicine, light textile, electric power, ship, metallurgy, energy resource system.There is problems with use in existing gate valve：There is gap between gate valve body bottom and flashboard bottom, this gap position easily stores fluid when valve plate is opened, when the temperature around gate valve is relatively low, this segment fluid flow easily freezes, the normal of influence gate valve is used.
The content of the invention
The present invention is directed to above-mentioned technical problem, there is provided gap is difficult to store the pneumatic cast steel gate valve of fluid between a kind of gate valve body bottom and flashboard bottom.
The technical solution adopted in the present invention is：
A kind of pneumatic cast steel gate valve, it is characterised in that：Including valve body,Flashboard,Connect liquid box,Connecting tube,Bonnet,Cylinder,Valve rod,One end of the valve body offers fluid inlet and its other end offers fluid issuing,The inside of the valve body offers and the fluid inlet,The valve pocket that fluid issuing is communicated,The bottom of the valve body offers through hole,Diameter of the diameter on the through hole top less than bottom,The inside of the valve pocket is fixed with the first fixed seat being oppositely arranged,Second fixed seat,In first fixed seat the first sealing ring is fixed with towards the side of flashboard,In second fixed seat the second sealing ring is fixed with towards the side of flashboard,The flashboard is located at the inside of the valve pocket and it is located in first fixed seat,Between second fixed seat,The bottom of the flashboard is connected by connecting rod with closure,The lower end of the connecting rod is arranged in the through hole,Diameter of the diameter of the connecting rod less than through hole,The size of the closure is identical with the size of through hole and its lower end is arranged at outside through hole,It is described connect liquid box be fixed on the valve body bottom and its communicated with through hole,One end of the connecting tube with connect that liquid box is communicated and its other end is communicated with fluid issuing,Micropump is fixed with the connecting tube,Flowmeter,The bonnet is fixed on the top of the valve body,The cylinder is fixed on the top of the bonnet,One end of the valve rod and cylinders and its other end passes through bonnet,Valve body is connected with flashboard.
The 3rd sealing ring is fixed with inside the through hole.
The 4th sealing ring is provided between the valve rod, valve body.
The valve body is cast steel valve body.
Beneficial effects of the present invention are：
1st, in gate valve body bottom open up through hole in the present invention and be additionally arranged sealing cover structure, moved on flashboard, valve opening, fluid passes through, and closure is blocked in through hole, fluid will not be produced to leak, when flashboard is moved down, valve closing, the lower end of closure outside through hole to moving, the fluid of gap storage is entered by through hole and connect in liquid box between gate valve body bottom and flashboard bottom, prevents gate valve from freezing；
2nd, when connecing the arrival of the fluid in liquid box and being a certain amount of, micropump is opened, and the fluid connect in liquid box enters fluid issuing, prevents from connecing liquid storage in liquid box along connecting tube, and reflowing result is good；
3rd, the setting of flowmeter, is easy to count amount of refluxed liquid；
4th, cylinder band ovable valve stem is moved up and down, and realizes that flashboard is opened and closed, high degree of automation, without manual hand manipulation；
5th, the setting of multiple sealing rings, good sealing effect.
