Abstract
The invention discloses a chlorine valve of a double-seal structure. The chlorine valve comprises a valve cover, a valve body, a valve clack, a valve rod and a valve base. As an improvement, the chlorine valve is characterized in that the double-seal structure is arranged at the end of the valve clack, a double-seal surface is arranged on the valve clack and composed of conical surfaces and planes, and an anti-abrasion layer is arranged on the double-seal surface. According to a further improvement, the included angle between the conical surfaces of the double-seal structure is 65-75 degrees, and the included angle between the planes is 6-12 degrees. The chlorine valve has the advantages of being good in seal performance, long in service life, good in safety, free of maintenance and leakage, very safe, very reliable, and high in anti-corrosion capacity.
Description
Technical field
The present invention relates to a kind of valve, particularly a kind of chlorine conveying pipelines special valve, belongs to chemical industry dedicated medium conveyance conduit valve field.
Background technique
In the past, the chlorine valve of chemical industry for making chlorine and alkali industry, was generally common valve.Common valve is from material or structure does not possess special-purpose feature, under deep-etching, poisonous and hazardous process conditions, and poor sealing performance often, easily leak, housing is easily bored a hole, and working life is short, can not meet the specific (special) requirements of permanently effective conveying poisonous medium.Once chlorine leaks, can bring serious consequence to surrounding enviroment and personal safety.
In recent years, the specific (special) requirements of carrying according to poisonous, easy leaking medium, some defects of using for existing valve, in technology, announced now many about preventing the technological scheme of the valve special for chlorine of chlorine leakage, still, from practice, the chlorine conveying pipelines special valve of prior art still has certain deficiency, sealing reliability is good not enough, and long-term use sometimes still has a little and leak, also fall short of working life, Security not enough.
Summary of the invention
What the present invention will solve is the deficiency that after the long-term use existing in prior art, sealing is not good, working life is not long, and a kind of double sealing structure chlorine valve is provided.
The present invention is achieved through the following technical solutions technical goal.
Double sealing structure chlorine valve, comprises valve gap, valve body, flap, valve rod, valve seat, and its improvements are: described flap end is provided with double sealing structure, has the double-sealing face consisting of the conical surface, plane on flap, and described double-sealing face is provided with wearing layer.
As a further improvement on the present invention, the conical surface angle of described double sealing structure is 65～75 degree, and described plane included angle is 6～12 degree.
As of the present invention, further improve, be processed with horse shoe shaped groove and swallow tail shaped slot on described valve seat, the interior filled polytetrafluoroethylene resin of groove is also integrally formed with metallic matrix.
As of the present invention, further improve, on described double-sealing face, wearing layer is teflon composite bed.
Adopt technique scheme, tool of the present invention had the following advantages:
1, sealing is more reliable.On flap, be processed with double sealing structure, this double sealing structure is more more reliable than single sealing configuration in the past.
2, longer service life.Flap end is processed with the centrums of 5～15 degree, and when valve open, medium, along centrum surface shunting, has solved the difficult problem that flat end medium washes away valve seat, improves valve working life more than ten times.
3, on double-sealing face, wearing layer is teflon composite bed, makes the present invention wear-resisting, corrosion-resistant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the present invention is described in further detail below.
Double sealing structure chlorine valve as shown in Figure 1, comprise valve gap 10, valve body 2, flap 3, valve rod 9, valve seat 7, it is characterized in that: flap 3 ends are provided with double sealing structure, on flap 3, there is the double-sealing face 4 being formed by the conical surface, plane, in the present embodiment, the conical surface angle of double sealing structure is 70 degree, and plane included angle is 10 degree.On valve seat 7, be processed with horse shoe shaped groove and swallow tail shaped slot 5, the interior filled polytetrafluoroethylene resin of groove is also integrally formed with metallic matrix.Double-sealing face 4 is provided with wearing layer, and in the present embodiment, on double-sealing face 4, wearing layer is teflon composite bed.
