Abstract
The utility model provides a hard -sealing and high -temperature ball valve, including the turbine that is located the top, the turbine below is fixed with the support, the leg joint has the axle sleeve, on personally experiencing sth. Part of the body during the axle sleeve is fixed in, well body both ends are fixed with the lateral body, in the internal spheroid that is equipped with, be fixed with the valve rod of connecting the turbine on the spheroid, it has the disk seat to serve the embedding in the lateral body, be equipped with the ascending pretension spring of lateral body axle between the installation face of disk seat and the lateral body, be equipped with the scraper on the sealed face of disk seat, the scraper front end is laminated with the spheroid surface mutually, it sweeps the hole to be equipped with in first one of the well body, in external portion be equipped with the blow down valve, the blow down valve with sweep the jogged joint, be equipped with the mudhole in the lower half of the well body, in external portion be equipped with the blowoff valve, the blowoff valve is connected with the mudhole. The utility model discloses a compactness rational in infrastructure through the little advantage of scraper area of contact, reduces disk seat and spheroidal friction, strikes off and attaches to spheroid particulate matter on the surface, and blow down valve cooperation blowoff valve forms a wiper mechanism, and body interior zone prolongs long life in effective the washing, and the effect is showing.
Description
Technical field
The utility model relates to valve field, specifically a kind of hard sealing high-temp. ball valve.
Background technique
At present along with a large amount of construction of industrial facility, increasing valve is used, and the kind of valve also gets more and more, and function gets more and more.Wherein the use of hard sealing high-temp. ball valve also gets more and more, and as a kind of parts being used for realizing pipe-line system break-make and flow control, obtains applying very widely in many fields such as oil, chemical industry, metallurgy, water power.In hard sealing high-temp. ball valve, spheroid and valve seat are due to matching relationship, there will be the situation of wearing and tearing, and the service time of valve seat is shortened, and are also not easy to cleaning based on the structure of valve inner, and easy retained foreign body, affects the reliability of ball valve.
Model utility content
The utility model will solve above-mentioned prior art Problems existing, provides a kind of hard sealing high-temp. ball valve, solves the problem of the easy to wear and valve inner of current valve seat not easy to clean.
The utility model solves the technological scheme that its technical problem adopts: this hard sealing high-temp. ball valve, comprise the turbine being positioned at top, support is fixed with below turbine, support is connected with axle sleeve, axle sleeve is fixed on middle body, middle body two ends are fixed with lateral body, spheroid is provided with in middle body, spheroid is fixed with valve rod, valve rod is connected with turbine, the inner is embedded with valve seat to lateral body, lateral body preloading spring is axially provided with between the attachment face of valve seat and lateral body, the sealing surface of valve seat is provided with scraper, scraper front end and spherome surface fit, the first half of middle body is provided with the purge hole in inside and outside portion in connection, middle external body is provided with blow down valve, blow down valve is connected with purge hole, the Lower Half of middle body is provided with the pollutant exhaust hole in inside and outside portion in connection, middle external body is provided with blowdown valve, blowdown valve is connected with pollutant exhaust hole.After arranging like this, while the horizontal position of fixing spheroid, preloading spring makes valve seat float, and the setting of scraper, for striking off the particulate matter be attached on spherome surface, ensures the sealing between valve seat and spheroid.Utilize the advantage that scraper into contact area is little, both can strike off the particulate matter on spherome surface, the friction between spheroid and valve seat can be reduced again while ensureing sealing, increase the service life; Blow down valve coordinates blowdown valve to carry out cleaning, and blow down valve first accesses air pump, utilizes gas to be blown out from blowdown valve by particulate matter, cleans further, namely on blow down valve, access water pipe, and with the region in water cleaning between body and spheroid, sewage flows out from blowdown valve.
Equal surfacing carbide alloy of nickel-base on spherome surface, valve seat sealing surface and scraper.Because spherome surface, scraper need to coordinate rotation, equal surfacing cemented carbide on valve seat sealing surface, spherome surface and scraper, through precise finish, sealing more reliably can be reached, expanded service life.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, compact, by the advantage that scraper into contact area is little, reduce the friction of valve seat and spheroid, reduce the wearing and tearing of valve seat, can also strike off the particulate matter be attached on spherome surface, blow down valve coordinates blowdown valve to form a wiper mechanism, body inner region in effective cleaning, expanded service life, Be very effective, is suitable for promoting.
