Abstract
The utility model discloses a valve plate with a dual seal structure. The valve plate with the dual seal structure comprises a valve rod and two semi-cycle valve clacks which are arranged on two sides of the valve rod and fixedly connected with the valve rod. A corrosion resistant layer is arranged on the surface of each semi-cycle valve clack. A layer of rubber seal cushion is arranged on the surface of the edge of each semi-cycle valve clack. An arc-shaped metal frame is arranged at the bottom end of each semi-cycle valve clack. A rubber layer is covered outside the metal frame, and the rubber layer and the metal frame are vulcanized to form a whole. The valve plate with the dual seal structure is simple in structure and provided with the dual seal structure, can improve tightness of the valve plate and prolongs service life.
Description
Technical field
The utility model relates to valve field, is mainly a kind of valve plate with double sealing structure, is applicable to butterfly valve.
Background technique
Butterfly valve is used widely on the general industries such as oil, coal gas, chemical industry, water treatment, thereby will carry when using and do its anticorrosion effect, to pay attention to sealing effect simultaneously, the valve plate on general butterfly valve has only adopted separately one the metal sealing muscle, although long service life, sealing effect is poor.
The model utility content
The technical problem of all solutions of the utility model provides a kind of valve plate with double sealing structure, and it is simple in structure, is provided with double-layer sealing structure, can improve the sealability of valve plate, is provided with simultaneously anti-corrosion layer, can increase the service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of valve plate with double sealing structure, two semicircle flaps that include valve rod, are located at the valve rod both sides and are fixedly connected with it, it is characterized in that: the outer one deck anti-corrosion layer that is respectively equipped with in the surface of described two flaps, the edge surface of described two halves round valve lobe is provided with one deck rubber gasket, be respectively equipped with the metal frame of arc on the bottom of described two halves round valve lobe, metal frame is coated with and its sulfuration all-in-one-piece rubber layer.
Also be provided with the stiffening rib that multiple tracks is intersected anyhow on described two flap surfaces.
In the utility model, the flap edge surface is provided with rubber gasket, also is provided with on flap in addition and metal frame sulfuration all-in-one-piece rubber sealant, and metal frame adds that rubber layer makes good sealing effect.
The utility model has the advantages that:
The utility model is simple in structure, is provided with double-layer sealing structure, can improve the sealability of valve plate, is provided with simultaneously anti-corrosion layer, can increase the service life.
Description of drawings
Fig. 1 is the utility model structural representation.
