Abstract
The utility model relates to a valve, in particular to a special valve for chlorine gas which is used for controlling and regulating the flowing of media on pipelines in chemical industry. The special valve for chlorine gas comprises a valve body, a valve seat, a valve clack, a valve deck, a gland, a valve rod, a driving nut and a hand wheel, wherein a ring groove is arranged at the position where the surface of the valve seat is matched with the valve clack, a sealing component is arranged in the ring groove, and a hard alloy layer is arranged at the position where the surface of the valve seat is matched with the valve clack, and is matched with a sealing component on the surface of the valve seat. The special valve for chlorine gas has the beneficial effects of good sealing property and long service life.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to control and regulate on a kind of chemical industry pipeline the special valve for chlorine of media flow.
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 shutoff valve greatly, because the irrationality of sealability and structure, cause the Sealing damage that easily comes off, easily leak, even security incident takes place, valve is short working life, change frequently, influence is produced, and causes very serious economy loss and inevitably potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide the valve special for chlorine of a kind of good seal performance, long service life.
The purpose of this utility model is achieved in that a kind of valve special for chlorine, comprise valve body, valve seat, flap, valve gap, gland, valve rod, transmission nut, handwheel, the position that described valve base surface cooperates with flap is provided with circular groove, in the described circular groove Sealing is set, the position that described flap surface cooperates with valve seat is provided with hard alloy layer, and described hard alloy layer matches with the Sealing of valve base surface.
As a kind of improvement of the present utility model, the circular groove of described valve base surface is a dovetail groove, and its width of rebate is less than the bottom land width.
Valve base surface of the present utility model is equipped with circular groove, and Sealing is set in the circular groove, and Sealing is firm at the circular groove internal fixation, and difficult dislocation comes off, and good seal performance is safe and reliable; The flap surface is equipped with hard alloy layer, and hard alloy layer and flap are sintered to one substantially, and the flap wear-resisting property is good, long service life.
In sum, the utlity model has the beneficial effect of good seal performance, long service life.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of valve special for chlorine, comprise valve body 1, valve seat 2, flap 3, valve gap 4, gland 5, valve rod 6, transmission nut 7, handwheel 8, the position that valve seat 2 surfaces cooperate with flap 3 is provided with circular groove 9, Sealing 10 is set in the circular groove 9, and the material of Sealing 10 is a teflon, and the position that flap 3 surfaces cooperate with valve seat 2 is provided with hard alloy layer 11, hard alloy layer 11 is sintered to one with flap 3, and hard alloy layer 11 matches with the Sealing 10 on valve seat 2 surfaces.The circular groove 9 on valve seat 2 surfaces is a dovetail groove, and its width of rebate is less than the bottom land width.
During use, rotation hand wheel 8 drives valve rod 6, flap 3 upper and lower displacements, and flap 3 separates with valve seat 2 when to top offset, is valve opening; When flap 3 during to bottom offset, flap 3 coincide with valve seat 2 and connects, and is valve closing.
