Technical field
The utility model relates to gate valve, and especially a kind of wear resistant corrosion resistant is with the gate valve of ceramic chamber lining.
Background technique
Gate valve is the controlling component in pipe-line transportation system, for controlling the keying of transfer passage.Now, in order to the control of the abrasive media conveyings such as some particles, lime-ash, ore pulp can be adapted to, ceramic embedded lining in the media transport path of gate valve has been started, to improve the wear-resisting of gate valve and decay resistance.As within 05 26th, 2010, disclosed, a patent No. is ZL200920190375.3, name is called the utility model patent of " wear-resistant ceramic knife gate valve ", it comprises valve body, flashboard, valve rod, handwheel, support, Sealing and assembling set, mainly in the valve channel of flashboard both sides, ceramic chamber lining is installed, complement each other to form sealing pair between this ceramic chamber lining and flashboard, flashboard is the corrosion resistant plate that surface has nitride layer.This gate valve can be used as the switching device of the abrasive media pipelines such as conveying particle, lime-ash, ore pulp.But because its flashboard adopts surface to have the corrosion resistant plate of nitride layer, manufacture cost is higher, and after nitride layer wearing and tearing, the sealability of gate valve will be affected.
Model utility content
The technical problems to be solved in the utility model is to provide the gate valve of a kind of wear resistant corrosion resistant with ceramic chamber lining, and its flashboard wear-resisting property is good, and conveniently moving, manufacture cost is lower.
For achieving the above object, the technical solution of the utility model is: a kind of wear resistant corrosion resistant is with the gate valve of ceramic chamber lining, comprise valve body, flashboard, valve body is provided with media transport path and the flashboard active tunnel perpendicular to media transport path, flashboard is contained in the flashboard active tunnel of valve body, the operating device that the affixed operation flashboard in top of valve body moves up and down, the valve body media transfer passage of flashboard both sides is inlaid with two annular ceramic chamber linings, bi-side, flashboard bottom are gluedd joint has ring-shaped pottery layer to match with the end face of two annular ceramic chamber linings, the flashboard active tunnel top of valve body is equipped with Sealing and is matched with the side of two in the middle part of flashboard.
Further improvement, two ring-shaped pottery layer exterior edge faces of described flashboard both sides form herringbone structure, and two ring-shaped pottery linings end face in opposite directions forms herringbone structure.By the wedge-like engagement of two ring-shaped pottery layer exterior edge faces and two ring-shaped pottery bush end face, the sealability that gate valve is closed effectively can be improved; Two ring-shaped pottery layer exterior edge faces and two ring-shaped pottery bush end face wear extenies can be compensated simultaneously, extend the working life of gate valve.
Preferred described operating device comprises the lower seat board be connected mutually with valve body, by the upper base plate that many bolts are connected mutually with lower seat board, lower seat board is provided with a through hole, upper base plate is installed with a screw rod, the top of screw rod spins mutually with a handwheel, rotating handwheel can drive screw rod to move up and down, and flashboard is hinged through the lower end of the through hole on lower seat board and screw rod.
Preferred described Sealing is stuffing box packing, and be in the upper end of valve body in the through hole that Sealing is contained in lower seat board, Sealing matches with the outer side surface of flashboard, lower seat board is also equipped with a briquetting and pushes down described Sealing.
Further improvement, the bottom of described valve body is provided with the tapped hole that is communicated with described flashboard active tunnel, and described tapped hole is rotary with chock plug.Outwarding winding chock plug can the buildup of easy cleaning flashboard active tunnel, prevents flashboard stuck or close not in place.
The utility model, owing to being inlaid with two annular ceramic chamber linings on the valve body media transfer passage of flashboard both sides, then glueing joint in bi-side, flashboard bottom and has ring-shaped pottery layer to match with the end face of two annular ceramic chamber linings.When such gate valve is closed, the ring-shaped pottery layer exterior edge face of bi-side, flashboard bottom is sealed and matched mutually with the end face of two annular ceramic chamber linings, play the effect of isolating valve body medium transfer passage, be sealed and matched mutually by the ring-shaped pottery layer of bi-side, the flashboard bottom end face with two annular ceramic chamber linings, just can prevent the wearing and tearing of gate panel body, improve the wear-resisting property of flashboard, and manufacture cost is lower.Flashboard both sides adopt ring-shaped pottery layer to be sealed and matched mutually with the end face of two annular ceramic chamber linings in addition, and can also reduce mutual friction area, reduce frictional force, convenient driving flashboard moves.
