Abstract

The utility model relates to a corrugated pipe stop valve for chlorine, in particular to a corrugated pipe stop valve for chlorine for controlling and regulating the flow of medium on a pipeline in the chemical industry. The corrugated pipe stop valve comprises a valve body, a valve seat, a valve flap, a valve cap, a corrugated pipe, a valve rod, a gland and a hand wheel, wherein a gasket is arranged between the valve cap and the valve body, an annular seal ring is arranged between the valve rod and the corrugated pipe, the upper end of the corrugated pipe is welded at the upper end of the valve cap, and the lower end thereof is welded on the valve rod or the valve flap; an annular groove is arranged on the surface of the valve seat, and a sealing piece is arranged inside the annular groove; a hard alloy layer is positioned on the surface of the valve flap, sintered into a whole with the matrix of the valve flap and matched with the sealing piece on the surface of the valve seat. The stop valve has the advantages of good sealing property, uneasy falling and damage, uneasy leakage, long service life, low maintenance frequency, good frictional resistance of the valve flap, and high safety and reliability.

Description

The special-purpose bellows stop valve of chlorine
Technical field
The utility model relates to a kind of valve, relates to the special-purpose bellows stop valve of chlorine of controlling and regulate media flow on a kind of chemical industry pipeline specifically.
Background technique
At present, the valve that China's chemical industry is used for the control of deep-etching flowing medium such as chlorine mostly is common stop valve greatly, form and structure are unreasonable owing to be tightly connected, the Sealing damage that easily comes off is easily leaked, even security incident takes place, valve is short working life, change frequently, influence is produced, and causes economic loss.
The model utility content
The purpose of this utility model is to provide a kind of sealing configuration novelty, and good seal performance is safe and reliable, the special-purpose bellows stop valve of the chlorine of long service life.
The utility model comprises valve body, valve seat, flap, valve gap, bellows, valve rod, gland, handwheel, between above-mentioned valve gap and the valve body pad is set, between above-mentioned valve rod and the bellows O-ring seal is set, the upper end of described bellows is welded on the upper end of valve gap, and the lower end of bellows is welded on valve rod or the flap; Above-mentioned valve base surface is provided with circular groove, and Sealing is set in circular groove; Above-mentioned flap surface is equipped with hard alloy layer, and hard alloy layer and flap matrix are sintered to one, and above-mentioned hard alloy layer matches with the Sealing of valve base surface.
The utility model good airproof performance, difficult drop-off damages, the difficult leakage, long service life, frequency of maintenance is low, and the flap crocking resistance is good, and is safe and reliable.
The circular groove of above-mentioned valve base surface is a dovetail groove, and its width of rebate is not more than the bottom land width.Be beneficial to fixed seal ring, difficult dislocation comes off, and good seal performance is safe and reliable.
The hard alloy layer on above-mentioned flap surface is the awl plane structure, and cone angle can be made as 60 °, can strengthen the sealing of sealing surface.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of flap and valve seat.
