Abstract

The utility model relates to a double-sealing sanitary mix-proof valve which belongs to the field of fluid controllers, and comprises a valve core, a seal ring gland, a lathedog snap ring, a self-lubricating strip, a seal ring, a valve body, an O-shaped ring, a guide part and the like; a design technology of single-valve and two seal rings is adopted, and a leakage cavity is formed between for mixing prevention and separation in a pipe system; the spherical valve structure prevents sanitation dead corners, and is convenient to clean; an open support design separates the valve and an actuator, so as to inspect shaft sealing and prevent the heat transfer between the valve and the actuator; a metal stopping mechanism ensures the compression degree of a valve seat area, and reduces the sealing pressure and load of a valve seat; a wear resistant elastic shaft seal is combined with a bushing, to greatly prolong the service life of the sealing; a lathedog are used to connect the valves and connect the valve and the actuator, and facilitates detachment and installation; CIP pipe-type double-seat valve design is adopted, so that the cleaning does not block the work of a main process, to achieve the purposes of safety, flexible and clean automatic operation, so that a plurality of pipes can work simultaneously, and the service life is prolonged.

Description

Double-sealing health mixing-preventing valve

Technical field:

The present invention relates to a kind of fluid control device, especially adopt the two seals technology, anti-the mixing that is used for pipe-line system separated, and by the separating surface between two fluids, prevented that material is contaminated.

Background technique:

At present, mixing-preventing valve in industry such as food processing industry, wine brewing, beverage production, pharmacy and fine chemistry industry, its complex structure, take up space greatly, not easy care, have dead angle, sealing property undesirable, cause liquid from a pipe leakage to another pipeline, material is contaminated easily, is not easy to clean, and takes precautions against poor effect, befouling environment can improve product cost simultaneously greatly.

Summary of the invention:

Mixing-preventing valve in existing food processing industry, beverage production, pharmacy and the fine chemistry industry industry exists not enough.The invention provides a kind of double-sealing health mixing-preventing valve of fluid control device, by spool, seal ring gland, clip trim ring, moisten bar, seal ring, valve body, O shape circle, guiding element etc. certainly and form, have dead angle simple in structure, no, multitube road characteristics such as work simultaneously.

The technical solution adopted for the present invention to solve the technical problems is: adopt single valve Pan Liangdaomifengquan design, form one between it and leak the chamber, anti-the mixing that is used for pipe-line system separated; The spherical valve body structure has been avoided the corner or spot as yet untouched by a clean-up campaign, is convenient to clean; Open support Design is separated valve and final controlling element, is convenient to shaft sealing is checked, has also prevented the heat transmission of valve and final controlling element; The metal chocking construction guarantees the degree of compression of valve seat area, reduces the pressure and the load of valve base sealing; Wear-resisting elastic axis envelope and axle bush composite structure have increased the life-span that seals greatly; Between the valve body, adopt clip connected between valve body and the final controlling element, be convenient to dismounting; Adopt the design of CIP take-over type double seated valve, cleaning can the work of overslaugh main procedure.

The invention has the beneficial effects as follows: automation mechanized operation safety, flexibly, cleaning, multitube road work simultaneously, increases working life.

Description of drawings

Fig. 1 is product structure figure.

Among the figure, 1, secondary spool 2,, valve body 3, O shape circle 4, seal ring gland 5, connect support 6, cylinder block 7, by device 8, piston 9, spring 10, clip 10, one-level spool

Embodiment

One-level spool (10) is put into valve body (2), one-level spool (10) and secondary spool (1) are coupled together with the axle center; Seal ring gland (4) is coupled together with clip (10) and valve body (2), again secondary spool (1) is inserted in the seal ring of seal ring gland (4); Seal ring gland (4) is pressed on the valve body (2), again clip (10) is got up cylinder (6) and valve body (2) card; To be contained on the piston (8) by device (7) again, control interface will be contained on the cylinder (6); When valve cut out, last lower valve chamber was all by independent valve disc sealing; During opening of valves, following valve disc promotes, and valve disc touches valve disc instantly, and separate cavities is closed; When following valve disc promoted to go up valve disc to the valve complete opening, valve was opened fully; After O shape circle (3) damaged, the liquid of following pipeline will be discharged from secondary spool (1), can not pollute pipeline; After O shape circle (3) damaged, the liquid of last pipeline will be discharged from secondary spool (1), can not pollute pipeline down; After the main gas mouth air inlet, one-level spool (10) secondary spool (1) will move upward simultaneously, and the liquid of pipeline mixes up and down; After the air inlet of following valve mouth, one-level spool (10) moves upward, and drains and goes up the remaining thing of pipeline; After the air inlet of last valve mouth, secondary spool (1) moves downward, the remaining thing in the cavity of secondary spool capable of washing (1); Cleaning is not when using, and one-level spool (10) improves cavity, keeps clean, by spring (9) sealing gland; The product that leaks can flow to and leak in the chamber, and discharges through detecting valve; Can carry out original position to this valve and clean the CIP operation, only need to get final product to pneumatic head supply pressurized air.

Claims

1. double-sealing health mixing-preventing valve, by spool, seal ring gland, clip trim ring, moisten bar, seal ring, valve body, O shape circle, guiding element certainly and form, it is characterized in that: design single valve dish two seals loop mechanism in pipe-line system, valve body is a ball shape, support Design is an Open architecture; Elastic axis envelope and axle bush composite structure adopt clip connected; Adopt CIP take-over type double seated valve structural design.

2. double-sealing health mixing-preventing valve according to claim 1 is characterized in that valve and final controlling element separate.

3. double-sealing health mixing-preventing valve according to claim 1 is characterized in that forming between the seal ring on the valve disc cavity.
