Abstract
The invention discloses an adjusting valve specially used for chlorine gas, comprising a valve body, a valve clack, a valve cap, a gland bush, a valve stem and a hand wheel. A washer is arranged between the valve cap and the valve body; an annular sealing ring is arranged between the lower end of the valve cap and the valve stem. The differences are that: a loop groove is arranged on the surface of the valve base and a sealing part is arranged in the loop groove; a hard alloy layer is arranged on the surface of the valve clack and combined with the sealing part on the surface of the valve base. The adjusting valve specially used for chlorine gas has the advantages of novel sealing structure, good sealing performance, safety and reliability and long service life.
Description
Technical field
The present invention relates to a kind of valve, relate in particular to the regulating valve special for chlorine door of controlling and regulate media flow on a kind of chemical industry pipeline.
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 sealed attachment form and structure are unreasonable, 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.
Summary of the invention
The object of the present invention is to provide a kind of sealing configuration novelty, good seal performance, safe and reliable, the regulating valve special for chlorine of long service life.
The technological scheme that the present invention solves its technical problem is: a kind of regulating valve special for chlorine, it comprises valve body, valve seat, flap, valve gap, gland, valve rod, handwheel, be equipped with pad between above-mentioned valve gap and the valve body, be equipped with O-ring seal between above-mentioned valve gap lower end and the valve rod, difference is, above-mentioned valve base surface is equipped with circular groove, above-mentioned circular groove is built-in with Sealing, above-mentioned flap surface is equipped with hard alloy layer, above-mentioned 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 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.
Above-mentioned flap bottom is the convex body.
Above-mentioned pad, O-ring seal, Sealing are teflon.
The present invention compared with prior art has following advantage:
1, the valve base surface of this regulating valve special for chlorine is equipped with circular groove, and circular groove is built-in with Sealing, and Sealing is firm at the circular groove internal fixation, and difficult dislocation comes off, and good seal performance is safe and reliable.
2, the flap surface of this regulating valve special for chlorine is equipped with hard alloy layer, and hard alloy layer and flap matrix are sintered to one, and the flap scratch-resistant performance is good, long service life.
3, the pad of this regulating valve special for chlorine, O-ring seal, Sealing are teflon, and be corrosion-resistant, not yielding, good seal performance, long service life.
Description of drawings
Fig. 1 is the structural representation of regulating valve special for chlorine of the present invention.
Embodiment
Below in conjunction with accompanying drawing regulating valve special for chlorine of the present invention is further described.
As shown in Figure 1, a kind of regulating valve special for chlorine, it comprises valve body 1, valve seat 2, flap 3, valve gap 4, gland 5, valve rod 6, handwheel 7, be equipped with pad 41 between above-mentioned valve gap 4 and the valve body 1, be equipped with O-ring seal 42 between above-mentioned valve gap 4 lower ends and the valve rod 6, difference is, above-mentioned valve seat 2 surfaces are equipped with circular groove 21, above-mentioned circular groove 21 is built-in with Sealing 22, above-mentioned flap 3 surfaces are equipped with hard alloy layer 31, above-mentioned hard alloy layer 31 is sintered to one with flap 3 matrixes, and above-mentioned hard alloy layer 31 matches with the Sealing 22 on valve seat 2 surfaces; The circular groove 21 on above-mentioned valve seat 2 surfaces is a dovetail groove, and its width of rebate is not more than the bottom land width; Above-mentioned flap 3 bottoms are convex body 32; Above-mentioned pad 41, O-ring seal 42, Sealing 22 are teflon.
During use, handwheel 7 rotation drives valve rod 6, flap 3 upper and lower displacements, and when to top offset, flap 3 separates with valve seat 2, valve open, and when flap 3 during to bottom offset, flap 3 and valve seat 2 apical graftings, valve closing.
