Abstract
The utility model discloses a stop valve. The stop valve comprises a valve body, a valve seat and a valve rod; a metal sheet is embedded into the valve body; and the valve seat is formed by combining and connecting a seat core and a seat body. The seat core is made of a metal material or a wear-resisting nonmetal material; and the seat body is made of a plastic material. The stop valve has the advantages that: the valve seat in the stop valve consists of the seat core and the seat body which are made of different materials, the seat core is made of the wear-resisting material or metal, and the seat body is made of plastic, so the weight of the valve seat is greatly reduced, and production cost of the valve seat is greatly reduced, and the metal sheet which is embedded into the valve body can be changed into an embedded plastic piece to reduce weight and production cost further.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of stop valve.
Background technique
Stop valve is that the indispensable part on the pipeline is widely used in to water supply, industries such as generating, chemical industry, medical treatment, and existing stop valve is made up of valve body, valve seat, valve rod; In valve body, be embedded with the tinsel of band internal thread; Valve seat is made of metal, the tinsel scyewed joint in metal seat valve and the valve body, valve rod and metal seat valve scyewed joint; Because the sheet in valve seat and the valve body be a metallic material all, cause existing stop valve weight than greatly and cost of production high.
The model utility content
The purpose of the utility model provides the stop valve of a kind of novel structure, in light weight, environmental protection and energy saving, low cost of manufacture.
The technological scheme of the utility model is: comprise valve body, valve seat and valve rod, valve body is embedded with a tinsel, and valve seat is connected by seat core and pedestal and forms.
The seat core adopts metallic material or wear-resisting nonmetallic material to process, and pedestal adopts plastic materials to process.
Tinsel adopts plastics to process.
The beneficial effect of the utility model: because the seat design in the stop valve is become to be made up of seat core and pedestal two-part; And two-part material is different; The seat core adopts high-abrasive material or metal to process; Pedestal adopts plastics to process, and so just can make the weight of valve seat reduce the also reduction greatly of cost of production that makes valve seat simultaneously greatly, also can make the embedded metal part in the valve body into embedded working of plastics in order further to reduce weight and cost of production.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the valve seat construction schematic representation.
Embodiment
Like Fig. 1, Fig. 2, the utility model comprises valve body 1, valve seat and valve rod 3, and valve body 1 is embedded with a tinsel 5, and valve seat is formed by seat core 2 and pedestal 4 injection moulding pressings.Seat core 2 can adopt metallic material or wear-resisting nonmetallic material to process, and pedestal 4 adopts plastic materials to process.Above-mentioned tinsel 5 can adopt plastics to process.
Claims (3)
