Abstract
The utility model discloses a lost foam used for casting the valve body of a stop valve. The lost foam comprises a valve body molding piece molded by extrusion, wherein the two ends of the valve body molding piece are respectively provided with an inlet and an outlet; the upper end and the lower end of the valve body molding piece are respectively provided with openings; the valve body molding piece is internally provided with a partition plate integrally formed by extrusion molding; the inside of the valve body molding piece is divided into two valve chambers by the partition plate; and the central part of the partition plate is provided with a through hole. The lost foam disclosed by the utility model is reasonable in structure, high in molding rate, economic and environment-friendly; and by using the lost foam, the sealing performance of the cast stop valve is enhanced, cost is lowered, the casting process is simplified.
Description
Technical field
The utility model relates to disappearance mould field, is specifically related to a kind of disappearance mould that is used to cast the stop valve valve body.
Background technology
Stop valve also is pipe valve, is to use the most a kind of valve, and why very popular it is; Be that Lift is little, and is easy to manufacture owing to frictional force between the sealing surface in the switching process is little, more durable; Easy to maintenance, in not being only applicable to, low pressure, and be applicable to high pressure.
Existing stop valve adopts casting technique production mostly, and cost is higher, complex process, and uneconomical environmental protection, and be easy to generate waste product.
The utility model content
The purpose of the utility model provides a kind of disappearance mould that is used to cast the stop valve valve body, improves the sealing property of casting back stop valve, reduces cost.
The technical scheme of the utility model is following:
A kind of disappearance mould that is used to cast the stop valve valve body; It is characterized in that: include valve body plastic through extrusion moulding; The two ends of said valve body plastic are respectively equipped with import and export, and the upper and lower end of valve body plastic is respectively equipped with opening, and the inside of valve body plastic has through the integrated dividing plate of extrusion molding; Described dividing plate is separated into two valve pockets with the inside of valve body plastic, and the middle part of dividing plate is provided with through hole.
The described disappearance mould that is used to cast the stop valve valve body is characterized in that: the edge, surrounding around valve body plastic upper and lower end opening is respectively equipped with a plurality of installing holes.
The described disappearance mould that is used to cast the stop valve valve body is characterized in that: be installed with the tubular valve seat in the said through hole.
The beneficial effect of the utility model:
The utility model is rational in infrastructure, has improved the sealing property of casting back gate valve, has reduced cost, has simplified casting technique, and ratio of briquetting is high, economic environmental protection.
