Abstract
The utility model discloses a coal dust ball valve, belonging to the valve designing and manufacturing technique for conveying grain material medium, composed of a valve body, a spherical body valve clack and a valve rod. An inlet and an outlet of a flange on the left and right of the valve body are provided with wearing sleeves. Guideway sleeves of an inner spring are arranged in the inlet and the outlet of the flange on the left and right of the valve body. Spring thrust acts on a valve body seal component. The spherical body valve clack treated through carburization is arranged in the valve body, and the center of the spherical body valve clack is eccentric to the center line of the valve rod. The utility model has the advantages of reasonable structure, high abrasion resistance of the ball valve circulation diameter, long service life, tight mating between the seal component and the spherical surface of the ball caused by the spring action, good tightness, and lasting sealing. The utility model can be used for a particle material medium conveying and controlling system.
Description
The utility model belongs to the design and fabrication technology field of valve mechanism, refers in particular to the valve that is used for the granule materials medium transport.
At present, the valve body of the ball valve of common use, spheroid flap and valve rod constitute, spheroid flap intermediate throughholes, when through hole and valve seat when align in the hole, medium passes through, otherwise then ends.Its shortcoming one is, valve body import and export passage is easy to wear, and service life is short; The 2nd, one-way sealing ball valve, coal dust easily are collected in the valve body, because pressure and the postponement of time, the coal dust in the valve body becomes cementing status, increase to open and close resistance; The 3rd, valve volume is big, is difficult for processing and manufacturing.
It is strong that the purpose of this utility model provides a kind of resistance to abrasion, good airproof performance, the easily Coad dust ball valve of processing and manufacturing.
The purpose of this utility model is to realize like this, it is made of valve body, spheroid flap and valve rod, flange is equipped with wearing bush into and out of product in the valve body left and right sides, at valve body left and right sides flange uniform guide rail sleeve that inner spring is housed in the product, spring thrust acts on valve seal spare, cementation process spheroid flap is contained in the valve body by valve rod, spheroid flap center and valve rod line of centers off-centre.Valve rod drives the rotation of spheroid flap, finishes the opening and closing action.
The utility model has the advantages that rational in infrastructurely, improved the anti-friction of ball valve circulation latus rectum, increase the service life.The spring axial thrust is used in sealing member, and valve seal spare is tightly cooperated with spheroid flap sphere, seals, and spring thrust can not increase switching moment, and sealing is lasting.Adopt two way seal that coal dust can only be flowed in passage, installation direction is arbitrarily.Divide the body structure valve body, make the foundry goods miniaturization, processing, assembling and maintenance are all very convenient, the saving fund.Utilize the eccentric rotary principle, when one of spheroid flap rotation very low-angle, spheroid flap sphere just leaves certain distance with valve seal spare, and spheroid is rotated further subsequently, does not produce friction drag, reduces to wear and tear.Valve seal spare material can be according to customer requirements, adopts hard material sealing or soft material sealing, sealing band be have self-lubricating, can not glued wear-resistant material.
Following structure accompanying drawing and enforcement just are elaborated to the utility model
Figure is the utility model structural representation
This Coad dust ball valve is made of valve body, spheroid flap and valve rod, at valve body (1) left and right sides flange (3) import and export wearing bush (6) is housed, the uniform guide rail sleeve (4) that inner spring (5) are housed in the flange import and export of the valve body left and right sides, spring thrust is used in valve seal spare (7), cementation process spheroid flap (2) is contained in the valve body by valve rod, spheroid flap center and valve rod line of centers off-centre.Can reach the purpose of this utility model, serviceability temperature through using :-25 ℃～+ 250 ℃, operation pressure :≤4.0MPa.Be applicable to the granule materials medium transport, can be widely used in industries such as metallurgy, chemical industry, mine.
Claims (2)
1. Coad dust ball valve, constitute by valve body, spheroid flap and valve rod, it is characterized in that wearing bush (6) being housed at valve body (1) left and right sides flange (3) import and export, the uniform guide rail sleeve (4) that inner spring (5) are housed in the flange import and export of the valve body left and right sides, spring thrust acts on valve seal spare (7), spheroid flap center and valve rod line of centers off-centre.
