Description
Technical field
The utility model relates to a kind of parallel flange formula double-flashboard gate valve.
Background technique
Double disk parallel gate valve is applicable to chemical industry, oil, natural gas, power plant, colliery, building, iron and steel, the industry such as light industry and sewage treatment.Because often having the object such as hard particles and fibrous dirt in medium, this valve in pipe-line system as start-stop device, fabulous effect can be played, its way of propelling has manual, pneumatic and electronic etc., which employs the sealing surface of spring self sealing structure and special type, no matter make sealing pair remain identical in any position, thoroughly can strike off the residual soil (as the attachment such as silt, welding slag) that sealing surface bonds, sealing surface is not subject to any damage, the corrosion resistant alloy material of high hardness due to sealing surface weld deposit; Existing gate valve in use, strengthen when when especially using under bad working environments, the adhesive force of sealing surface is not closed, the optimizer that unlatching is and can diminishes, the thrust that the increasing of sealing force can only rely on MEDIA FLOW to produce realizes, and therefore direction, mounting point is limited, and Simultaneous Switching resistance is large, switching time is long, poor reliability, the life-span is short, and can not use under the industrial and mineral environment inferior that impurity content is higher.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of parallel flange formula double-flashboard gate valve that can use under severe industrial and mineral environment.
The utility model solves the technological scheme that its technical problem adopts: a kind of parallel flange formula double-flashboard gate valve, there is valve body, water intake and the water outlet of described valve body are provided with flange plate, flange plate is provided with some installation tapped holes, valve body is provided with valve gap, seal ring is provided with between valve body and valve gap, the center position of valve body is provided with valve rod, the top of valve rod is provided with handwheel, handwheel lower end is provided with Stem Mut, the lower end of valve rod is provided with valve plate, the bottom end of valve rod is provided with column cap, can use under containing the industrial and mineral environment inferior of higher impurity, switch resistance is little, reliability is high, long service life, reduce cost of production.
Further, described valve body adopts grey cast steel material to make, and extends the working life of product, reduces cost of production.
Further, the quantity of described tapped hole is 5-10, and the quantity of tapped hole is 8, improves the stability of valve body in installation process and fixed performance, ensures that flanged surface not easily seal leakage occurs.
Further, the sealing surface of described valve body is welded with corrosion resistant alloy material, the extremely strong leak-down rate of sealing is zero on the one hand, substantially increases the work working life of valve on the other hand, for enterprise has saved cost.
The beneficial effects of the utility model are: the utility model structure is simple, use and easily manufactured, have good sealability, sealing surface not easily produces damage, and can use under containing the industrial and mineral environment inferior of higher impurity, switch resistance is little, reliability is high, long service life, reduces cost of production.
