Abstract
A high temperature and corrosion resistant valve comprises a valve body, a valve core and a valve rod, and is characterized in that the valve body, the valve core and the valve rod are made of crystal glass or quartz glass; a metal layer is combined with the outer surface of the valve body; a metal rod body is arranged in the valve rod; a core body is arranged in the valve core, and connected with the inner end of the metal rod body in the valve rod. The high temperature and corrosion resistant valve has the advantages that the crystal glass or quartz glass is relatively high in hardness and high temperature resistance and relatively low in expansion coefficient, so that the abrasion, corrosion and high temperature resistance properties of the high temperature and corrosion resistant valve are improved, the precision change caused by temperature variation is reduced, the possibilities of deformation and cracking are low, and the service life of the high temperature and corrosion resistant valve is prolonged.
Description
Technical field
The present invention relates to a kind of valve, particularly a kind of have valve that is high temperature resistant, decay resistance.
Background technique
Traditional valve is generally made up of valve body, spool and valve rod, each several part all adopts metal (as iron, common steel or stainless steel) manufacture to form, for the environment that service condition is comparatively harsh, the such as service condition such as corrosive fluid, high temperature fluid, just easily be corroded and reduction of service life, deform due to high temperature, even burst, less stable; Some valves, in order to improve corrosion resistance, are provided with anticorrosive coat on the surface of valve and medium contact, but this technological scheme can reduce again the hardness of parts, thus reduce wear resistance, cause shorten working life.
Summary of the invention
The present invention aims to provide a kind of high temperature resistant, corrosion resistant valve, solves the existing valve manufactured by metal in corrosion resistant performance and the poor problem of resistance to high temperature.
Technological scheme of the present invention is: a kind of high temperature resistant, corrosion resistant valve, comprise valve body, spool and valve rod, it is characterized in that, described valve body, spool and valve rod are made up of crystal glass or silica glass.
Metal layer is compounded with at described valve outer surface.
The material being compounded in the metal layer of described valve outer surface comprises iron, steel or other high hardness metals.
Metallic rod body is provided with in described valve rod.
In described spool, be provided with core body, this core body is connected with the inner of the metallic rod body in described valve rod.
The material being located at the metallic rod body in described valve rod comprises iron, steel or other resistant to elevated temperatures metals.
Described core body is made up of crystal glass or silica glass.
Advantage of the present invention is: utilize crystal glass or silica glass to have the characteristic of higher hardness, high temperature resistant and lower expansion coefficient, improve wear-resisting, corrosion-resistant and resistance to high temperature, reduce the precision caused by temperature variation to change, strain cracking is less likely to occur, extends working life.
Accompanying drawing explanation
Fig. 1 is the general structure sectional view of the first embodiment of the present invention;
Fig. 2 is the general structure sectional view of the second embodiment of the present invention.
Embodiment
As shown in Figure 1, the first embodiment of a kind of valve of the present invention, comprises valve body 1, spool 2 and valve rod 3, is conventional configurations, it is characterized in that, described valve body 1, spool 2 and valve rod 3 are made by crystal glass or silica glass.
The second embodiment of the present invention, its structure is identical with a upper embodiment, and difference is, is compounded with metal layer (not shown) at described valve body 1 outer surface.The material of this metal layer comprises the metal or alloy that iron, steel (as stainless steel) or other high hardness rather have certain toughness, plays the protective action to valve body 1.Various embodiment of the present invention all can adopt this technological scheme.
As shown in Figure 2, the third embodiment of the present invention, its structure is same as the previously described embodiments, difference is, metallic rod body 31 is provided with in described valve rod 3, in described spool 2, be provided with core body 21, this core body 21 welds with the inner of the metallic rod body 31 in described valve rod 3, be threaded or be structure as a whole.
The material being located at the metallic rod body 31 in described valve rod 3 comprises iron, steel or other resistant to elevated temperatures metals.
In this embodiment, also can be provided with metallic rod body 31 in valve rod 3 only separately, or only in described spool 2, be provided with core body 21, described core body is made up of crystal glass or silica glass
Crystal glass and silica glass have higher hardness (Mohs seven grades), high temperature resistant (operating temperature more than 1000 degrees Celsius) and lower expansion coefficient.This bi-material belongs to acid material, and except hydrofluoric acid and hot phosphoric acid, all showing as inertia to other any acid, is best acid resisting material.Therefore the present invention adopting this material to make has high temperature resistant, corrosion-resistant and wear-resisting property well, and can be applied to the switch of the flowing medium controlling high temperature, working life improves greatly.
