The technical scheme that this utility model adopts is:
A kind of anti-freeze type cast steel gate valve, it is characterized in that: include valve body, flashboard, connect liquid box, connecting tube, valve gap, cylinder, valve rod, one end of described valve body offers fluid inlet and its other end offers fluid issuing, the inside of described valve body offers and described fluid inlet, the valve pocket that fluid issuing communicates, the bottom of described valve body offers through hole, the diameter on described through hole top is less than the diameter of bottom, the inside of described valve pocket is fixed with the be oppositely arranged first fixing seat, second fixing seat, described first fixing seat is fixed with the first sealing ring towards the side of flashboard, described second fixing seat is fixed with the second sealing ring towards the side of flashboard, described flashboard is positioned at the inside of described valve pocket and it is located in the described first fixing seat, between second fixing seat, the bottom of described flashboard is connected with sealing lid by connecting rod, the lower end of described connecting rod is arranged in described through hole, the diameter of described connecting rod is less than the diameter of through hole, described seal lid size is identical with the size of through hole and its lower end is arranged at outside through hole, the described liquid box that connects is fixed on the bottom of described valve body and it communicates with through hole, one end of described connecting tube with connect liquid box and communicate and its other end communicates with fluid issuing, described connecting tube is fixed with micropump, effusion meter, described valve gap is fixed on the top of described valve body, described cylinder is fixed on the top of described valve gap, one end of described valve rod and cylinders and its other end traverse valve gap, valve body is connected with flashboard.
The 3rd sealing ring it is fixed with inside described through hole.
The 4th sealing ring it is provided with between described valve rod, valve body.
Described valve body is cast steel valve body.
The beneficial effects of the utility model are:
1, this utility model is offered through hole bottom gate valve body and has been additionally arranged sealing cover structure, flashboard moves, valve opening, fluid passes through, and seals cap seal and gets lodged in through hole, fluid leakage will not be produced, when flashboard moves down, valve closing, the lower end sealing lid is outside mobile to through hole, between bottom gate valve body and bottom flashboard, the fluid of gap storage is entered by through hole and connects in liquid box, it is prevented that gate valve freezes;
2, when the fluid connect in liquid box arrives a certain amount of, micropump is opened, and the fluid connect in liquid box enters fluid issuing along connecting tube, it is prevented that connect liquid storage in liquid box, and reflowing result is good;
3, the setting of effusion meter, it is simple to the statistics backflow scale of construction;
4, cylinder band ovable valve stem moves up and down, it is achieved flashboard opens and closes, and automaticity is high, it is not necessary to manual hand manipulation;
5, the setting of multiple sealing rings, good sealing effect.
