Abstract
The utility model discloses a high-strength leakage-proof type flange disk which comprises a flange disk main body with an inner hole. A plurality of bolt holes are distributed on the flange disk, an arc groove for connecting two bolt holes is arranged between every two bolt holes, an arc reinforced rib is fixedly installed in the arc groove, a step-shaped annular groove is arranged on an installation face of the flange disk around the inner hole, a step-shaped sealing ring corresponding to the step-shaped annular groove is arranged at the back of the flange disk, an upper step of the step-shaped sealing ring is a rubber sealing gasket, and an outwards-protruded conical ring integrally connected with the inner hole is arranged at the back of the flange disk. The high-strength leakage-proof type flange disk is simple in structure and convenient to use, effectively enhances mechanical strength and sealing performance, remarkably reduces side effects on stability and sealing performance of connection positions caused by vibration and uneven stress of pipes, and effectively guarantees normal using and safety.
Description
Technical field
The utility model relates to a kind of flange plate, is specially a kind of high strength Anti-leakage type flange plate.
Background technique
Flange plate is a kind of mechanical parts for connecting two pipe fittings, and the two flange plate correspondence that will be fixed on two pipe fittings by bolt during use connects, to finish the connection to pipe fitting.In industrial pipeline, the use that flange connects is very extensive.And existing flange plate mechanical strength is not good, and when connecting two pipe fittings, its joint sealing is not good yet, and easily causes its connective stability and sealing to descend because of pipe vibration or unbalance stress, and then affects using effect and Security.
The model utility content
The purpose of this utility model provides a kind of high strength Anti-leakage type flange plate, not good to solve flange plate mechanical strength traditional in the prior art, when connecting two pipe fittings, its joint sealing is not good yet, and easily cause its connective stability and sealing to descend because of pipe vibration or unbalance stress, and then affect the problem of using effect and Security.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of high strength Anti-leakage type flange plate, include the flange plate body that has endoporus, be distributed with several bolts hole on the described flange plate, it is characterized in that: between per two bolts hole, be provided with the arc groove that connects two bolts hole on the described flange plate, be installed with the arc stiffening rib in the described arc groove, be provided with the stepped shape annular groove around endoporus on the attachment face of described flange plate, the back side of described flange plate is provided with the stepped shape seal ring corresponding with the stepped shape annular groove, topping bar of described stepped shape seal ring is rubber gasket, and the described flange plate back side is outwardly the tapered collar that is connected as a single entity with endoporus.
Described a kind of high strength Anti-leakage type flange plate is characterized in that: described arc stiffening rib does not protrude from the flange plate attachment face after being fixedly mounted in the arc groove.
Described a kind of high strength Anti-leakage type flange plate, it is characterized in that: the oral area of described stepped shape annular groove is provided with chamfering.
Described a kind of high strength Anti-leakage type flange plate, it is characterized in that: the degree of depth of described stepped shape annular groove is 5-15mm.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, employing arranges the design of stiffening rib at flange plate, enhancing effectively the mechanical strength of flange plate, guaranteed the working life of flange plate, employing arranges match stepped shape annular groove and stepped shape seal ring on the flange plate two sides, and the design of the tapered collar that is connected as a single entity of setting and endoporus, so that two flange plate cooperate closely, effectively promoted flange plate sealing in use, significantly slacken pipe fitting vibration and unbalance stress and the adverse effect of and sealing stable to the flange plate joint, effectively guaranteed normal use and the Security of flange plate.
