Abstract
The invention discloses a novel shutoff valve, which comprises a valve body, a valve seat and a valve rod, wherein a steel sheet is embedded in the valve body; the valve seat is formed by combing and connecting a seat core with a seat body. The seat core is made of a metal material or a wearable nonmetal material; the seat body is made of a plastic material. The novel shutoff valve has the beneficial effects that, as the valve seat in the shutoff valve is designed to consist of two parts of the seat core and the valve body, further, the two parts are made of different materials, the valve core is made of a durable material or metal, the valve seat is made of plastic, in this way, the production cost of the valve seat is also greatly decreased while the weight of the valve seat is greatly decreased, and to further decrease the weight and the production cost, an embedded metal component in the valve body can be also changed into an embedded plastic component.
Description
Technical field
The present invention relates to a kind of stop valve.
Background technology
The indispensable part that stop valve is on pipeline is widely used in water supply, the industries such as generating, chemical industry, medical treatment, existing stop valve is made up of valve body, valve seat, valve rod, valve body is embedded with the steel disc with internal thread, valve seat is made of metal, the steel disc thread connection in metal seat valve and valve body, valve rod and metal seat valve thread connection, owing to the sheet in valve seat and valve body is all metal material, cause existing stop valve weight relatively big and production cost is high.
Summary of the invention
It is an object of the invention to provide the stop valve of a kind of novel structure, lightweight, environmental protection and energy saving, low cost of manufacture.
The technical scheme is that and include valve body, valve seat and valve rod, valve body is embedded with a steel disc, and valve seat is combined by seat core and pedestal and is formed by connecting.
Seat core adopts metal material or wear-resisting nonmetallic materials to make, and pedestal adopts plastic material to make.
Steel disc is adopted made of plastic.
Beneficial effects of the present invention: owing to becoming to be made up of seat core and pedestal two parts by the seat design in stop valve, and two-part material is different, seat core adopts high-abrasive material or metal to make, pedestal is adopted made of plastic, the weight of valve seat thus can be made to be substantially reduced makes the production cost of valve seat be greatly reduced simultaneously, also can make the embedded metal part in valve body into embedded working of plastics to reduce weight and production cost further.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is valve seat construction schematic diagram.
Detailed description of the invention
Such as Fig. 1 and Fig. 2, the present invention includes valve body 1, valve seat and valve rod 3, and valve body 1 is embedded with a steel disc 5, and valve seat is formed by seat core 2 and pedestal 4 injection moulding pressing.Seat core 2 can adopt metal material or wear-resisting nonmetallic materials to make, and pedestal 4 adopts plastic material to make.Above-mentioned steel disc 5 can be adopted made of plastic.
