Abstract

The utility model discloses a bush-type ore slurry disconnection gate valve which comprises a valve stem and a flashboard and further comprises a left valve body and a right valve body. The flashboard is connected with the valve stem; a handwheel is connected with the valve stem which is arranged in a bracket; the left valve body and the right valve body are connected with each other; the bracket is connected with the left valve body and the right valve body; a bush is arranged between the left valve body and the right valve body; and a flow passage of the left valve body and the right valve body is coated by the bush. Because the flow passage of each valve body of the valve is provided with the bush, the valve is abrasion resistant and has long service life; the replacement is convenient at low cost; the bush-type disconnection gate valve is durable; and if the disconnection gate valve is broken because of abrasion, only the bush needs to be replaced, so that the cost is lowered greatly.

Description

Bush type ore pulp disconnecting link valve
Technical field
The utility model belongs to the disconnecting link valve, is specifically related to a kind of ore pulp disconnecting link valve.
Background technique
The disconnecting link valve of using on the ore pulp system pipe network all is the common knife gate valve of carbon steel or magnesium iron valve body at present, the ore pulp medium directly contacts with valve flowing channel, because contain a large amount of solid grits in the ore pulp medium, rub between grit and the valve body, short period is interior just with valve body wearing and tearing even worn out, in a single day the anticorrosive coat of valve body surface is worn away, and has accelerated the corrosion of valve body again, and valve can not seal even damage very soon like this.Therefore, the ore pulp disconnecting link valve of said structure can only be used one or two months, and its working life is short, the replacement cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of anti abrasive bush type ore pulp disconnecting link valve, to address the above problem.
The technical solution of the utility model is: bush type ore pulp disconnecting link valve, it comprises valve rod, the flashboard that is connected with valve rod, connect handwheel on the valve rod, valve rod is located in the support, and it also comprises interconnective left valve barrel and right valve barrel, support is connected with left and right sides valve body, be provided with lining between the valve body of the left and right sides, lining coats the runner of left and right sides valve body, and flashboard is inserted in the lining.
Lining comprises guide bush, and guide bush is that the runner lining of left and right sides valve body, guide bush are provided with flashboard slot down, and the runner lining is provided with the annular damper seal groove.
Because this valve runner has lining, valve is wear-resistant.The valve body of common knife gate valve with ore pulp medium contact process in, be easy to be worn even worn out, thereby valve produces soon and leaks or be damaged, generally can only be with one to two months; And adopt bush type disconnecting link valve, ore pulp medium only contacts with lining, and to deal with soft tactics just more wear-resistantly firmly like this, lining is difficult for being worn, and valve generally can use more than 5 years; Valve is corrosion-resistant.The valve body of common knife gate valve is generally carbon steel or magnesium iron, easily is corroded at the ore pulp medium, and the valve body surface anticorrosive coat post-etching that in a single day is worn is just faster; And adopting bush type disconnecting link valve, ore pulp medium only to contact with lining, lining is polyurethane or teflon material, all is suitable corrosion-resistant material, thereby makes more durable of valve; It is convenient to change, and replacement cost is low.Common disconnecting link is when using in the ore pulp system, and valve is changed frequent, and the replacing of whole valve, and is with high costs; And bush type disconnecting link valve durable even it is bad to wear and tear, only needs more resleeve, and cost reduces greatly.
