Abstract
A F4 seal rubber pad belongs to the seal field of chemical equipment, containing a cirque-shaped gasket body, which is characterized in that the outside of the gasket body is added with an orientation rubber ring. A round bolt through hole is evenly processed on the orientation rubber ring and at the same time the both sides of the gasket body are processed respectively with at least one annular waterproof convex ring, the outer surface of the gasket body is processed with a polytetrafluoroethylene antisepsis layer integrated with the gasket body. With above improvement and the combination of the advantages of different materials of prior art seal gaskets, the utility model has the advantages of good compressibility and rebound elasticity, ageing resistance, strong seal effect, good corrosion resistance and being convenient for construction.
Description
Technical field
The utility model belongs to the chemical industry equipment field of sealing technology, specifically is a kind of F4 encapsulate pad.
Background technique
In the present all kinds of chemical industries, it no matter is the connection between the parts, still the connection of flange between the pipeline, all need corresponding seal washer, the F4 seal washer on plane is one of the most frequently used seal washer of present chemical industry, but the sealing packing ring in use finds to have existed the deficiency of poor flexibility, and because of being plane structure, easy quick aging along with the seal washer material, phenomenon is leaked in the race that industrial chemicals takes place, and, when construction, be difficult for adjusting angle of swing, install not in place, finally cause equipment to use the back poor because of overall tightness, cause the plant maintenance cycle short, thereby influence the ordinary production order of enterprise, so the technician of relevant industries is being devoted to address this problem for many years always.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, advantage according to each seal washer unlike material, structure to above-mentioned all kinds of seal washers is optimized improvement, thereby it is good to design a kind of compressibility and rebound elasticity, anti-aging, sealing effect is strong, good corrosion resistance, the F4 encapsulate pad of being convenient to construct.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is a kind of F4 encapsulate pad, comprise circular packing ring matrix, the outer end that it is characterized in that the packing ring matrix is compounded with the location rubber ring, Equal round is processed with bolt hole on the rubber ring of location, the two sides of packing ring matrix is processed with at least 1 protruding circle of annular waterproof respectively simultaneously, and the outer surface at the packing ring matrix is processed with the anticorrosive PTFE layer, and this anticorrosive PTFE layer and packing ring matrix are compound to be one.
Be the waterproofing effect of enhanced leaktightness packing ring, the two sides of packing ring matrix is processed with the protruding circle of annular waterproof of at least 2～5 reducings respectively successively.
Be the antiseptic effect of enhanced leaktightness packing ring, the outer surface integral coating of packing ring matrix has the anticorrosive PTFE layer.
In addition, angle of swing to seal washer when installing for the ease of the workmen is adjusted, the outer end of location rubber ring is processed with at least 1 and outwards visits the rotation lug handle of stretching, this rotation lug handle and location rubber ring uniform thickness, and this rotation lug handle can be ellipse or square structure.
The utility model owing to made up the advantage of each seal washer unlike material of prior art, therefore has compressibility and rebound elasticity is good after above-mentioned improvement, anti-aging, sealing effect is strong, good corrosion resistance, the advantage of being convenient to construct.
Description of drawings
Fig. 1: the utility model embodiment cross-sectional configuration schematic representation.
The A of Fig. 2: Fig. 1 is to structural representation.
Among the figure: 1 location rubber ring, 2 bolt holes, 3 anticorrosive PTFE layers, 4 packing ring matrixes, the protruding circle of 5 annular waterproof, 6 rotation lug handles.
Embodiment
As Fig. 1, shown in Figure 2, this F4 encapsulate pad, comprise circular packing ring matrix 4, the outer end that it is characterized in that packing ring matrix 4 is compounded with location rubber ring 1, Equal round is processed with bolt hole 2 on the rubber ring 1 of location, the position of bolt hole 2 and quantity, actual conditions according to equipment are decided, the two sides of packing ring matrix 4 is processed with at least 1 protruding circle 5 of annular waterproof respectively simultaneously, and the outer surface at the packing ring matrix is processed with anticorrosive PTFE layer 3, this anticorrosive PTFE layer 3 is compound with the packing ring matrix to be one, and the packing ring matrix can be EPDM or rubber according to the difference of used environment.
Be the waterproofing effect of enhanced leaktightness packing ring, the two sides of packing ring matrix 4 is processed with the protruding circle 5 of annular waterproof of at least 2～5 reducings respectively successively.
Be the antiseptic effect of enhanced leaktightness packing ring, the outer surface integral coating of packing ring matrix has anticorrosive PTFE layer 3.
In addition, angle of swing to seal washer when installing for the ease of the workmen is adjusted, the outer end of location rubber ring 1 is processed with at least 1 and outwards visits the rotation lug handle of stretching 6, the length of rotation lug handle 6 is according to the difference of water-tight equipment or caliber, to expose outside the outer surface of water-tight equipment or caliber, be convenient to hand by being standard, this rotation lug handle 6 and location rubber ring 1 uniform thickness, this rotation lug handle 6 can be ellipse or square structure, like this, the workmen just can be with hand by the rotation of pulling rotation lug handle 6 realizations to whole seal washer.
The utility model owing to made up the advantage of each seal washer unlike material of prior art, therefore has compressibility and rebound elasticity is good after above-mentioned improvement, anti-aging, sealing effect is strong, good corrosion resistance, the advantage of being convenient to construct.
Claims (5)
