Abstract
Provided is an anti-crystallization anti-scaling abrasion-resisting ball valve. A left valve body and a right valve body form a casing. The left valve body, a spring, a spring seat, a valve seat, a ball body, a valve seat, a spring seat, a spring, a right valve body are connected in sequence. A packing gland, a handle, a valve rod, the ball body and a fixing shaft are connected. A valve is a structure divided from the middle, the division surface of the left valve body and the right valve body is located on a central line of the valve rod, the ball body and the fixing shaft. The geometric shape and size of an inner cavity is symmetrical with the division surface as the symmetrical surface. A square tenon at the end of the valve rod is inserted into a chase mortise at the top of the ball body, one end of the fixing shaft is inserted into a blind hole at the lower portion of the ball body, and the other end of the fixing shaft is fixed in a positioning hole formed by the left valve body and the right valve body. The inner cavity arranged between the two valve seats of the left valve body and the right valve body is a spherical surface, and a small gap is reserved between the inner cavity and the ball body outer surface. Due to the small gap structure, the ball body surface is effectively prevent from crystallizing, and hardening treatment is performed to the ball body surface and the valve seat surfaces. Therefore, the ball body is abrasion-resisting, and the valve seats are not galled, thereby achieving ball body abrasion-resisting effect.
Description
Technical field
The present invention relates to a kind of wear resistance ball valve that does not form crystallization, fouling at spherome surface.
Background technique
Be called ball valve with spheroid as the valve of closure member, simple to operation quick because of it, be widely used in the commercial production pipelines such as pharmacy, chemical industry, oil, metallurgy, electric power, the energy, through the rotation of control spheroid, realize the keying of valve.Reach cost of production according to actual needs and consider that the body cavity and the gap between the outer surface of spheroid of conventional ball valve are more abundant, medium can get in the inner chamber of valve body.In some industry, in the relevant operation like pharmaceutical industry, ball valve is opened, closes quite frequent, whenever opening, closing once; The temperature of medium reduces, will be in the spherome surface crystallization, and the combination force of crystallization and spherome surface is quite big, owing to the crystallization of spherome surface; Hindered the rotation of spheroid, the square tenon of valve rod end is inserted in the tongue-and-groove at spheroid top, and valve rod drives spheroid and rotates; Will tear the groove of spheroid as opening by force or closing this moment, and valve can't be worked; Or, form roughened surface with the valve base surface plucking, and spheroid and valve seat blow-by, thus whole valve invalidation caused, must stop production and change valve, cause very big loss to production.Be not only pharmaceutical industry, other industry also has analogue.
Summary of the invention
In order to overcome existing ball valve causes crystallization and fouling easily at spherome surface problem; The present invention provides a kind of valve, does not allow spherome surface to cause crystallization and fouling, keeps the smooth of spherome surface; Do not increase the spheroid rotational resistance; All the time guarantee the excellent sealing of valve seat and spheroid, reach the wear-resisting effect of spheroid, keep the good operation of pipeline effectively.
Technological scheme of the present invention is: this ball valve is made up of left valve barrel, spring, spring seat, valve seat, spheroid, right valve barrel, valve rod, stationary axle, Gland, handle etc.Left valve barrel, right valve barrel are formed shell; Left valve barrel, spring, spring seat, valve seat, spheroid, valve seat, spring seat, spring, right valve barrel link to each other successively, and handle, Gland, valve rod connect successively, spherome surface sprayed wc cure process; The square tenon of valve rod end is inserted in the tongue-and-groove at spheroid top; There is a circular blind hole spheroid lower end, and stationary axle one end is inserted in the spheroid circular hole, and the other end is fixed in the positioning hole of left and right valve body composition.Valve seat adopts stainless steel material sealing surface sprayed wc cure process.This ball valve is a midsplit type structure; The separating surface of left and right valve body is on the shaft axis of valve rod, spheroid and stationary axle; The geometrical shape of right valve barrel and left valve barrel inner chamber, size are that symmetry plane is symmetrical with the valve body separating surface; Inner chamber is sphere between two valve seats, keeps micro-gap with outer surface of spheroid.
The invention has the beneficial effects as follows,, can realize that inner chamber is sphere between two valve seats of left and right valve body because this valve is the midsplit type structure; And keep constant with the gap of outer surface of spheroid,, make outer surface of spheroid no longer produce crystallization owing to have only microgap between them; Guarantee that valve is in steady-working state, the equal cure process of spherome surface and valve base surface in addition is so spheroid is wear-resistant; Can the plucking valve seat yet, long service life.
