Abstract
The utility model provides an outer screw connecting three-way adjustable rotary fan core sealing valve, which can be used for a dairy product pipeline of 250 DEG, the inner part of a valve core is made into a small eccentric convex shaft structure and the inner part of a valve body is fully sealed. A movable fan-shaped sealing surface is like being abraded, an inner hexagonal hole under a core shaft is used for adjusting an eccentric convex shaft slightly, an outer screw connecting pipe and the other through weld pipe are welded on the valve body and the purpose of direct seal and starting without leaking bearing force is achieved without cutting down the valve body welded on the pipeline by wind. The utility model has the advantages of compact structure, beautiful appearance, small volume, light weight and convenient use, installation and maintenance. The valve is an ideal substitute at present, the flow quantity of once entering and twice discharging or once entering and once discharging three-way transfer media can be controlled and adjusted, and the utility model is used for high sanitary grade pipelines of food industry, such as dairy products, milk products, lipide, etc.
Description
The utility model relates to the valve on a kind of pipeline, and threeway one opens and one close, one close a valving of opening.
At present, known dairy products stopcock grinds corruption by valve body and spool and forms, and can not bear pressure as the Gland pine and cause leakage, but pull motionlessly as the tight bat-handle switch of Gland, exists not reach sealing and two difficulties that manually comply with one's wishes.
The purpose of this utility model is:
A kind of external screw connection three-way adjustable rotary fan core seal valve is provided, can use the three-way valve on 250 ℃ of dairy product pipes, with making the protruding axle construction of small eccentricity in the spool, hermetically sealed in the valve body, movable fan-shaped sealing surface as wearing and tearing by mandrel down in the eccentric protruding axle of hexagonal fine setting make and be welded on the pipeline upper valve body and cut off without wind and directly reach sealing and open the purpose that bearing capacity is not leaked, compact structure, beautiful shape, volume is little, and is in light weight, uses I﹠M convenient.This valve is present desirable update product, controllable adjustable one-in-and-two-out or one-in-and-one-out, threeway transfer medium flow.
The purpose of this utility model is achieved in that
A kind of external screw connection three-way adjustable rotary fan core seal valve, form by valve body handle spool gland etc., it is characterized in that making in the spool the protruding axle construction of small eccentricity, fan-shaped sealing surface mechanical connection is on spool, fan-shaped sealing surface and valve body grind and coincide, and fan-shaped sealing surface is connected with sense of rotation positioning device shaft mechanical.
Owing to adopt such scheme, the utility model just can be under 250 ℃ of situations the one-in-and-two-out of pipeline or the threeway purpose of one-in-and-one-out.Be widely used on the high health grade of the food industry pipelines such as dairy products, milk products, grease.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is external screw connection three-way adjustable rotary fan core seal valve embodiment's a longitudinal sectional drawing.
In example shown in Figure 1:
Another logical outer spiral shell of the outer spiral shell connection of the fan-shaped sealing surface of the protruding Simmer ring of handle (1) key (2) spool (3) valve core seal ring (4) gland (5) socket head screw (6) upper press cover (7) valve body (8) rubber seal (9) socket head screw (10) small eccentricity (11) (12) adjustable revolving sector core holder (13) small eccentricity protruding axle protruding axle location (15) small eccentricity protruding axle tightening nut of (14) small eccentricity (16) (17) connects welded pipe (18) and forms the external screw connection three-way adjustable rotary fan core seal valve, fan-shaped sealing surface (12) valve body (8) grinds and coincide, good seal performance, one through hole closes, another through hole is opened, one-in-and-two-out or one-in-and-one-out.Appearing in the protruding axle of small eccentricity (14) below is that inner hexagonal hole is so that debugging sealing usefulness.Appearing as the fan-shaped sealing surface wear leakage direct levelling protruding axle of small eccentricity (14) below is inner hexagonal hole so that reach sealing purpose.Play slip and seal action by gland (5), spool (3) upper valve core seal ring (4), by the lock sealing effect of the protruding axle of the protruding axle of small eccentricity (14) small eccentricity protruding axle location (15) small eccentricity tightening nut (16).Seal ring (9) is pressed in the upper and lower seal groove of valve body (8) by screw (6), (10) with gland (7) and seals.Outer spiral shell connecting tube (17) is welded on the valve body (8) with another logical welded pipe (18).
Claims (1)
- A kind of external screw connection three-way adjustable rotary fan core seal valve, by handle, key, spool, valve core seal ring, gland, socket head screw, gland, valve body, rubber seal is formed, it is characterized in that the logical outer spiral shell of outer spiral shell connecting tube and another is connected welded pipe and is welded on the valve body, make the protruding axle construction of small eccentricity in the spool, fan-shaped sealing surface mechanical connection is on spool, fan-shaped sealing surface and valve body grind and coincide, fan-shaped sealing surface is connected with sense of rotation positioning device shaft mechanical, the protruding Simmer ring of small eccentricity, fan-shaped sealing surface, the adjustable revolving sector core holder, the protruding axle of small eccentricity, the protruding axle of small eccentricity setscrew nut, the protruding axle of small eccentricity tightening nut mechanical connection.
