Abstract
The utility model discloses a high temperature plug valve. The plug valve is formed by a valve body assembly, a valve cover, a lower end cover, a valve rod, a plug body and a drive device; the valve body assembly is formed by a valve seat and a valve body, wherein the valve seat is in welding-on connection with the valve body; the valve body is arranged in tamper cooperation with the plug body so that a good sealing effect is ensured; a protruding shaft which is arranged in rotating cooperation with a groove in the lower end cover is arranged in a rotating center at the bottom of the plug body; a shaft sleeve is arranged on the groove to prevent the plug body to move; fluid medium channels are arranged on two sides of the valve body assembly; a cylinder direct current medium channel is arranged in the plug body; a limit groove is arranged in the valve rod; and the valve rod is connected with the plug body via a T-shaped groove. According to the utility model, work pressure and work temperature of the valve are effectively increased, the valve can be opened after the plug body is lifted up and then rotates, abrasion of a sealing face is reduced, and service lifetime is prolonged.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of high temperature stopcock.
Background technique
Stopcock is a kind of valve that 90 ° of rotations realize valve snap switch of doing in valve body by cock body.Along with the application area of stopcock is more and more wider.Existing stopcock is mainly comprised of valve body, faucet body, filler and Gland, offers medium channel on valve body, and faucet body is provided with medium channel.During work, by handle with sleeve, drive faucet body to rotate, faucet body half-twist is realized fast opening and closing.But the stopcock of this structure is only applicable to low temperature, operating on low voltage occasion.For some high temperature and high pressure conditions, this kind of structure can not meet usability and requirement.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of high temperature stopcock that can work under High Temperature High Pressure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is to provide a kind of high temperature stopcock and comprises valve component, valve gap, lower end cap, valve rod, faucet body and drive unit, this valve component is comprised of by being welded together valve seat and valve body, this valve body and faucet body taper fit arrange, this rotating center place, faucet body bottom is provided with protruding axle, the groove that this protruding axle is placed in lower end cap is rotatably assorted, these valve component both sides are provided with fluid medium channel, in this faucet body, be provided with cylinder direct current medium channel, and weld Hardmetal materials at the sealing surface of described valve seat and the mutual precision-fit of faucet body.
By at sealing surface of seat and faucet body sealing surface weldering Hardmetal materials, realize high-temperature hard sealing, can under hot environment, carry out work.
Optimization as technique scheme: be provided with by guider screw on valve rod and be positioned at the guide position limiter that the restraining groove matching with guider screw on valve rod forms.
Further optimization as technique scheme: valve rod adopts T-shaped groove to be connected with faucet body.
Further optimization again as technique scheme: be provided with axle sleeve on groove.
The beneficial effects of the utility model are: working pressure and the operating temperature of the valve effectively improving, faucet body and valve body faucet body are done rotation and realized unlatching after rising, reduced the wearing and tearing of sealing surface, have increased working life.
Accompanying drawing explanation
Fig. 1 is high temperature stopcock structure schematic diagram.
Embodiment
The utility model embodiment is the utility model high temperature stopcock as shown in Figure 1, by valve component 1, valve gap 10, lower end cap 3, valve rod 8, faucet body 7 and drive unit 21 form, this valve component 1 is linked together and is formed by welding-on by valve seat 31 and valve body 32, the sealing surface weldering Hardmetal materials of this valve seat 31 and faucet body 7 mutual precision-fit, realize high-temperature hard sealing, this valve body 32 and faucet body 7 taper fit settings, the wearing and tearing of sealing surface have been reduced, increased working life, these faucet body 7 rotating center places, bottom are provided with protruding axle 24, the groove 25 that this protruding axle 24 is placed in lower end cap 3 is rotatably assorted, in groove 25, be provided with axle sleeve 6, form the anti-displacement structure of faucet body 7, these valve component 1 both sides are provided with fluid medium channel 26, in this faucet body 7, be provided with cylinder direct current medium channel 27.Gland 14 is fixed on valve gap 10 by bolt 15, plain washer 16 and nut 17, and filler 13 is sealed, and prevents from leaking outside.
