Abstract
Disclosed is a flat gate valve without deflector hole, which relates to a valve for pipelines. The flat gate valve without deflector hole comprises a valve body, two valve seats arranged in the valve body and a disc sandwiched between the two valve seats. The flat gate valve without deflector hole is characterized in that waist limiting blocks are arranged on the waists of the two valve seats, a bottom limiting part is arranged between the bottoms of the two valve seats, and the lower end of the disc is a circular arc crescent lower end which is in accordance with the inner diameters of the valve seats. The utility model has the advantages that the valve seats can not tilt and a sealing surface is small in damage and long in service life. Besides, the utility model is small in open torque and convenient in use.
Description
Technical field
The utility model relates to the valve of using on the pipeline, particularly be a kind of no pod apertures plate valve.
Background technique
Existing no pod apertures construction of parallel gate valve is two valve seat therebetween one flashboards, and the flashboard bottom is a circular arc, when valve wide open, flashboard has only the bottom circular arc to contact with valve seat top circular arc, surface of contact is little, valve seat under elastomeric effect, lower tilt and giving prominence to, form angle between two sealing surface of seats, when flashboard moved downward, flashboard strutted valve seat, thereby can damage sealing surface influence sealing, unlatching moment increases, and shortens the working life of valve.
The model utility content
The purpose of this utility model is intended to solve the valve seat tilt problem of above-mentioned no pod apertures plate valve, provides a kind of assurance two valve seat keeping parallelisms, to open moment little, the no pod apertures plate valve of long service life.
The purpose of this utility model realizes by limit stoper being set in valve body and changing flashboard lower end this technological means of shape.Concrete structure is, no pod apertures plate valve, comprise valve body, be arranged on two valve seats in the valve body, be clipped in the flashboard in the middle of two valve seats, it is characterized in that between the waist of described two valve seats, being provided with the waist limiting stopper, be provided with the bottom bounding means between two valve seats bottom, the lower end of described flashboard is the circular arc crescent shape lower end consistent with valve seat bore.
The utility model is provided with limit stoper by waist and the bottom at two valve seats, makes distance between two valve seats remain the size of flashboard thickness, two valve seat keeping parallelisms.So when opening/shutting valve, the frictional force between sealing surface is little, unlatching moment is little, thereby can prolong the working life of valve.Simultaneously; the flashboard lower end changes the crescent shape of downward circular arc into by original circular arc, and during at standard-sized sheet, the crescent shape plane of flashboard lower end contacts with first garden arc of sealing surface of seat at valve; make flashboard and valve seat that enough wide surface of contact arranged, can play the effect of protection sealing surface.
Compared with the aforementioned existing similar products, the utility model has the advantages that valve seat can run-off the straight, sealing surface is impaired little, long service life.Unlatching moment is little, uses easy and convenient.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Embodiment
Referring to Fig. 1～4, the formation of this nothing pod apertures plate valve comprises valve body 1, be arranged on two valve seats 2 in the valve body 1, be clipped in the flashboard 3 in the middle of two valve seats, it is characterized in that between the waist of described two valve seats, being provided with waist limiting stopper 7, be provided with bottom bounding means 8 between two valve seats bottom, the lower end 9 (referring to Fig. 5) of described flashboard is the circular arc crescent shape lower end consistent with valve seat bore.5 is valve gap among the figure, and 6 is bolt.What Fig. 6 provided is the structural representation of bottom bounding means.What Fig. 7 provided is the structural representation of waist limiting stopper.
