Abstract
A kind of good antiscale property stop valve of the utility model relates to valve technology field, and comprise valve body, described valve body is angle " T " shape, flap is provided with in described valve body, flap is connected with valve rod, is provided with valve gap above described valve body, valve rod is through valve gap, connect fastening above with Stem Mut, valve rod is provided with handwheel topmost, and is connected fastening by locking nut, is provided with filler between described valve rod and valve gap, there is hold-down grid above filler, and be connected by stud, nut and tighten together; The head chamfering place of the utility model product flap is provided with little barb, and time sealing pair contacts, barb can scrape the dirt stayed on valve seat off, forms a good sealing, reduces the scratch of sealing surface, and folder is husky; When valve will cancel sealing, flap leaves sealing surface, and barb also can scrape the dirt stayed on valve seat off, again clean valve seat.This stop valve can extend the working life of valve greatly, and too increases security seal.
Description
Technical field
The utility model belongs to valve technology field, specifically a kind of good antiscale property formula stop valve.
Background technique
The open-shut device of stop valve (stop valve, Globe Valve) is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat.The forms of motion of valve rod, also has lifting rotation rod-type, and stop valve refers to the valve of closure member along the movement of valve seat center line.According to this mobile form of flap, the change of valve seat port is and flap stroke direct proportionality.Valve rod due to such valve open or shutoff stroke relatively short, and there is cutting function very reliably, again due to the change of valve seat port and the stroke direct proportionality of flap, be very suitable for the adjustment to flow.Therefore, such stop valve valve is suitable as and cuts off or regulate and throttling use.
But stop valve of the prior art, operation is too complicated, can't realize dirt voluntarily, make troubles to work.Therefore, need technical progress, structural improvement, make the automaticity of stop valve higher.
Summary of the invention
The purpose of this utility model is, provides a kind of good antiscale property stop valve, in order to solve deficiency of the prior art, provides a kind of stop valve that can realize dirt voluntarily.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: a kind of good antiscale property stop valve, comprise valve body, it is characterized in that: in described valve body, be provided with flap, flap is connected with valve rod, valve gap is provided with above described valve body, valve rod is through valve gap, connect fastening above with Stem Mut, valve rod is provided with handwheel topmost, and is connected fastening by locking nut, is provided with filler between described valve rod and valve gap, there is hold-down grid above filler, and be connected by stud, nut and tighten together.
Described flap head chamfering place is provided with barb.
Described valve body is angle " T " shape place, is inside provided with the groove adapted with flap head barb.
Compared with prior art, the beneficial effects of the utility model are: the head chamfering place of the utility model product flap forms a little barb, in seal process, time sealing pair contacts, barb can scrape the dirt stayed on valve seat off, form a good sealing, reduce the scratch of sealing surface, folder is husky.When valve will cancel sealing, flap leaves sealing surface, and barb also can scrape the dirt stayed on valve seat off, again clean valve seat.This stop valve can extend the working life of valve greatly, and too increases security seal.
