Abstract
The utility model relates to a ball valve with an automatic ash scraping device, which is characterized in that two grooves are respectively arranged at two ends of a valve seat on the contact surface between the valve seat and a ball by adopting the center of the ball as a center, the two grooves are respectively arranged on two sides of a sealing ring of the ball valve, scraper springs are installed inside the grooves and are arranged at the front ends of the scraper springs, the front ends of the scraper blades contact with the ball, and two sides of each of the scraper blades are respectively provided with O-shaped rubber sealing rings. The ball valve with an automatic ash scraping device can effectively remove stove ashes adhered to the ball, so that abrasion of a sealing pair is slowed down, and the service life of the ball valve can be obviously prolonged by about three to six months. Accordingly, production cost is reduced and economic benefit is increased.
Description
Technical field
The utility model relates to a kind of ball valve of scraping apparatus for ash automatically that has.
Background technique
Existing Unloading ball valve is in the process of unloading ash, (be the needs of environmental protection owing to contain a large amount of moisture content in the ashes, prevent to occur in a large number dust, the water that adds some in the ashes, firmly pinch ashes and can pinch into bulk), under the double action of pipeline pressure and self gravitation, when making ashes pass through valve, ashes just stick on the spheroid of ball valve.In the process of valve opening and closing (spheroid rotation), ashes are entered between valve seat insert (teflon, rubber or antifriction metal (AFM)) and the spheroid, accelerated the wearing and tearing of seal ring and spheroid, thereby made the valve premature failure, reduce the working life of valve, generally be no more than 3-6 month.So just, increased the cost of production of enterprise.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: a kind of ball valve of scraping apparatus for ash automatically that has is provided, can strike off the ashes on the ball valve spheroid, ashes can not be entered between seal ring and the spheroid, seal ring and spheroid exempt from excessive wear and lost efficacy, and prolong the working life of ball valve.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of ball valve of scraping apparatus for ash automatically that has is provided, it is characterized in that: be the center with the center of circle, at the valve seat two ends, on valve seat and the face that spheroid contacts two grooves are set respectively, two grooves are separately positioned on the both sides of the seal ring of ball valve, install in the groove and scrape leaf spring, scrape the leaf spring front end scraper plate is installed, the preceding end in contact spheroid of scraper plate, the scraper plate both sides are separately installed with O type rubber seal.
Described groove number can be more than two.In order making the ashes on the ball valve spheroid to be scraped totally, several grooves also can be set more, be provided with in the groove and scrape leaf spring and scraping blade, it is unclean to prevent to scrape ash.
The described front edge of board of scraping is a wedge shape.Such shape is conveniently selected the storage of ashes in the process of assembling, after the also convenient rotation, and the discharge of ashes.
The beneficial effects of the utility model: by the setting of scraper plate, effectively eliminated the ashes that stick on the spheroid, delayed the wearing and tearing of sealing pair, obtained the remarkable result that increases the service life, approximately can prolong ball valve 3-6 month life-span, thereby reduce cost of production, increase economic benefit.
