Abstract
The utility model provides a sealing device, includes the steel ring, sealing washer, its characterized in that be provided with the bulge loop on the cross -section of steel ring both sides, the bulge loop matches with needing the groove phase on connecting tube or the equipment port, the sealing washer cup joints the outward flange both sides at the bulge loop respectively. Cup joint in the steel ring through the sealing washer, solved when carrying the special liquid of corrosivity in pipeline or equipment, produce corrosive effects to sealing washer self, lose sealed this condition of effect. Simultaneously setting up the bulge loop in the steel ring, having played the sealed effect of first way, the outward flange is sealed to be enclosed the second and says sealed effect, sealed effect will be well in general sealing washer. Set up the locating hole on the steel ring, the correspondence sets up the arch on the sealing washer, can fix the sealing washer the steel ring both sides when this sealing device of installation, the sealing washer can not appear and break away from the steel ring condition.
Description
Technical field
This utility model relates to technical field of sealing technology, is specifically related to a kind of sealing ring with steel ring.
Background technology
In modernization industrial processes, conveying gas, liquid or powdery granule, various pipeline can be used, as transport agent, pipeline inevitably uses sealing ring at connection equipment or bending place, and the selection of general sealing ring material is to its sealing property and important in inhibiting in service life, most of sealing rings are all rubber or macromolecular material, this sealing ring, when carrying corrosivity special liquid in pipeline, will produce corrosiveness to sealing ring self, slowly will lose sealing effectiveness.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that a kind of sealing device.
Technical problem to be solved in the utility model uses following technical scheme to realize:
A kind of sealing device, including steel ring, sealing ring, it is characterised in that be provided with bulge loop, bulge loop and the groove match need to being connected on pipeline or device port on described steel ring two lateral section, bulge loop plays metallic gasket and is used as first sealing.
Two lateral sections between described steel ring outward flange and bulge loop are provided with hole, location, and cross section, hole, location can be circular, triangle or rectangle, and hole, location circumferentially symmetric arrays, quantity can be 3 to 8, and adjacent spacing is equal.
Described sealing ring is socketed in the outward flange both sides of bulge loop, contacts side with steel ring and is provided with and positions the projection of hole respective shapes, is separately fixed at described steel ring both sides, when installing this sealing device, does not haves sealing ring and departs from steel ring situation.
Sealing ring opposite side cross sectional shape can be circular or rectangle.
The beneficial effects of the utility model are: be socketed in steel ring by sealing ring, solve when carrying corrosivity special liquid in pipeline or equipment, sealing ring self are produced corrosiveness, loses this situation of sealing effectiveness.Arranging bulge loop in steel ring simultaneously, serving first sealing effectiveness, outward flange seals and encloses second sealing effectiveness, and sealing effectiveness is better than general sealing ring.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is this utility model profile along 6-6 face.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As shown in Figure 1, 2, a kind of sealing device, including steel ring 1, sealing ring 3,4,1 liang of lateral section of steel ring is provided with bulge loop 2, bulge loop 2 and the groove match need to being connected on pipeline or device port.
Two lateral sections between steel ring 1 outward flange and bulge loop 2 are provided with hole 7, location, and positioning 7 cross sections can be circular, triangle or rectangle, and hole 7, location circumferentially symmetric arrays, quantity can be 3 to 8, and adjacent spacing is equal.
Sealing ring 3,4 is socketed in the outward flange both sides of bulge loop 2, contacts side with steel ring 1 and is provided with and positions the projection of hole 7 respective shapes, is separately fixed at steel ring 1 both sides.
Sealing ring 3,4 opposite side cross sectional shape can be circular or rectangle.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
