Description

A kind of seal arrangement

Technical field

The utility model is a kind of device for sealing, and is especially applied in a kind of seal arrangement of the liquid outlet side of filter plant.

Background technique

Traditional seal arrangement is to utilize two rubbing surfaces between end face to seal.An end face rotates (rotating ring), an end face motionless (stationary ring), and the spring of the outer end face of pressure between rubbing surface regulates.General rotating ring is metalwork, and stationary ring part is nonmetallic material.In traditional seal arrangement, non-metal part, without external refrigeration device, reduces its working life greatly; And because of the reason of a rubbing surface, as serious in there being an end wear in two end faces, cause the generation of the phenomenon of leakage.

Mainly there is following major defect in traditional seal arrangement at present: 1. between dynamic and static ring, both ends of the surface are poorly sealed, and especially equipment moved after a period of time, liquid leakage after contact surface abrasion.2. contact surface abrasion is very fast, changes frequent.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of seal arrangement, and sealing device can make the contact of filter plant liquid outlet sealing surface good, reduces the generation of the phenomenon of leakage.

For addressing the above problem, the technical solution of the utility model is:

, comprise rotating ring and valve body, on valve body, there is liquid outlet, on described valve body, by hexagon socket cap head screw, be fixed with sprue, on described valve body, with the adjacent end of rotating ring, be provided with sprue groove, in sprue groove, be provided with sprue; Sprue groove is communicated with coolant outlet and cooling water intake; The outside of sprue groove is provided with external sealed ring recess, in external sealed ring recess, be provided with exterior seal ring, on exterior seal ring, be inlaid with outer stationary ring, external sealed ring recess is communicated with the first compressed air inlet, the inner side of sprue groove is provided with inner seal ring groove, in inner seal ring groove, be provided with inner seal ring, be inlaid with interior stationary ring on inner seal ring, inner seal ring groove is communicated with the second compressed air inlet.

During use, utilize the first compressed air inlet, the second compressed air inlet on valve body to access respectively clean pressurized air, utilize the interior stationary ring of air pressure promotion that pressurized air provides to contact with rotating ring with outer stationary ring, reach the object of sealing; For making equipment durable in use, interior stationary ring and outer stationary ring material are carbon fiber filler teflon, and rotating ring is adopted as 2205 stainless steels; Utilize coolant outlet and external cooling water on valve body, cooling water is bottom in and top out simultaneously, by mobile cooling water, reduces the temperature of stationary ring, thereby extends the working life of stationary ring, improves equipment reliability; Can solve preferably the defects such as in filter plant, liquid outlet is poorly sealed, dynamic and static ring replacing is frequent.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Accompanying drawing 1 is the utility model embodiment's structural representation;

Accompanying drawing 2 is for removing the left view of the accompanying drawing 1 after rotating ring;

Accompanying drawing 3 is that the A-A of accompanying drawing 2 is to sectional view.

In figure: 1-valve body; 2-sprue; 3-inner seal ring; Stationary ring in 4-; 5-hexagon socket cap head screw; 6-exterior seal ring; The outer stationary ring of 7-; 8-rotating ring; 9-the first compressed air inlet; 10-coolant outlet; 11-the second compressed air inlet; 12-liquid outlet; 13-cooling water intake.

Embodiment

Embodiment, as shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, a kind of seal arrangement, comprise rotating ring 8 and valve body 1, on valve body 1, there is liquid outlet 12, on described valve body 1, by hexagon socket cap head screw 5, be fixed with sprue 2, on described valve body 1, with the adjacent end of rotating ring 8, be provided with sprue groove, in sprue groove, be provided with sprue 2; Sprue groove is communicated with coolant outlet 10 and cooling water intake 13; The outside of sprue groove is provided with external sealed ring recess, in external sealed ring recess, be provided with exterior seal ring 6, on exterior seal ring 6, be inlaid with outer stationary ring 7, external sealed ring recess is communicated with the first compressed air inlet 9, the inner side of sprue groove is provided with inner seal ring groove, in inner seal ring groove, be provided with inner seal ring 3, be inlaid with interior stationary ring 4 on inner seal ring 3, inner seal ring groove is communicated with the second compressed air inlet 11; Liquid outlet 12 external pipes.

Comprise that outer stationary ring 7 is embedded in exterior seal ring 6; Interior stationary ring 4 is embedded in inner seal ring 3, form two seals, then outer stationary ring 7 and exterior seal ring 6 assembly parties, interior stationary ring 4 are embedded in respectively in valve body 1 with the assembly parts of inner seal ring 3, sprue 2 utilizes hexagon socket cap head screw 5 to be assemblied on valve body 1 simultaneously, and the valve body 1 after whole like this assembling forms Double-contact surfaces sealing with rotating ring 8.

During use, utilize the first compressed air inlet 9, the second compressed air inlet 11 on valve body 1 to access respectively clean pressurized air, utilize the interior stationary ring 4 of air pressure promotion that pressurized air provides to contact with rotating ring 8 with outer stationary ring 7, reach the object of sealing; For making equipment durable in use, interior stationary ring 4 and outer stationary ring 7 materials are carbon fiber filler teflon, and rotating ring 8 is adopted as 2205 stainless steels; Utilize coolant outlet 10 and external cooling water 13 on valve body 1, cooling water is bottom in and top out simultaneously, by mobile cooling water, reduces the temperature of stationary ring, thereby extends the working life of stationary ring, improves equipment reliability.
