Abstract
The invention discloses a valve core of a flow valve. The valve core of the flow valve comprises a fan-shaped valve core body, wherein a wear-resisting layer is arranged on the circumference of the valve core body; a mounting part is arranged at the apex angle of the valve core body; a positioning hole is formed in the center of the mounting part; a plurality of connection holes are uniformly distributed in the periphery of the mounting part; the wear-resisting layer is 3-5 mm in thickness, and made of polymeric ceramic; both the valve core body and the mounting part are made of Ni-hard cast iron. When the valve core is in use, the wear-resisting layer is in contact with the valve cavity of the flow valve, so that not only is the wear resisting property improved, but also the service life of the valve core is prolonged; meanwhile, the production cost is reduced; through the connection between the mounting part and a valve rod, the mounting and the valve core replacement are facilitated; the valve core body and the mounting part are made of the Ni-hard cast iron, so that the decay resistance is improved.
Description
Technical field
The present invention relates to control valve field, be specifically related to a kind of Flow valve spool.
Background technique
Flow valve is mainly used in the water system needing to carry out flow control, is particularly suitable for heat supply, the flow control of the liquid mediums such as air-conditioning, applies very extensive.But, in the middle of prior art Flow valve spool because of its structural design unreasonable, also there is following deficiency: be mainly manifested in corrosion resistance and wear resistance is poor, and cost of production is higher.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of Flow valve spool, this spool wear resistance and corrosion resistance and good, and cost of production is lower, can be promoted the use of widely.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of Flow valve spool, comprise insert body, described insert body is fan-shaped, the periphery of insert body is provided with wearing layer, the drift angle place of described insert body is provided with an assembly department, the center of described assembly department is provided with a positioning hole, is evenly equipped with multiple attachment hole in the surrounding of assembly department, and the thickness of described wearing layer is 3-5mm.
Further, described wearing layer is made up of polymer-ceramic, and described insert body and assembly department are made by ni-hard cast iron.
Further, described assembly department and insert body one-body molded.
Further, the thickness of described insert body is 10-15mm.
A kind of Flow valve spool of the present invention, this spool comprises insert body and assembly department, only the periphery of insert body is provided with wearing layer, the thickness of wearing layer is at 3-5mm, in use, contacted with the valve pocket of Flow valve by wearing layer, not only increase the wear-resisting property of spool, improve the working life of spool, save cost of production simultaneously; Be connected with valve rod by assembly department, be convenient to install and change spool; Insert body and assembly department are made up of ni-hard cast iron, improve decay resistance.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
