Abstract
The utility model discloses a bending machine hydraulic pressure leakage-proof flange plate which comprises a flange plate body with inner holes. The flange plate is provided with a plurality of bolt holes. A step-shaped ring slot is arranged around the inner holes of a mounting surface of the flange plate. A step-shaped sealing ring corresponding to the ring slot is arranged on the back of the flange plate. An upper step on the step-shaped sealing ring is a rubber sealing washer. A conical ring is arranged on the back side of the flange plate and integrated with the inner holes, wherein the back side of the flange plate is protruding outside. The bending machine high-sealing flange plate is simple in structure, convenient to use, capable of effectively improving tightness of the flange plate when the flange plate is used, greatly reducing adverse influence from pipe fitting vibration and uneven force to the tightness of a flange plate joint, and effectively ensuring normal use and safety of the flange plate by the step-shaped ring slot and the step-shaped ring slot which are interacted and arranged on two sides of the flange plate and a design that the conical ring is integrated with the inner holes.
Description
Technical field
The utility model relates to a kind of flange plate, is specially a kind of bender hydraulic pressure anti-leakage flange dish.
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 is when connecting two pipe fittings, and its joint sealing is not good, and easily causes its connection 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 bender hydraulic pressure anti-leakage flange dish, to solve flange plate traditional in the prior art when connecting two pipe fittings, its joint sealing is not good, and easily cause its connection 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 bender hydraulic pressure anti-leakage flange dish, include the flange plate body that has endoporus, be distributed with several bolts hole on the described flange plate, it is characterized in that: 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 bender hydraulic pressure anti-leakage flange dish, it is characterized in that: the oral area of described stepped shape annular groove is provided with chamfering.
Described a kind of bender hydraulic pressure anti-leakage flange dish, 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 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 slackened pipe fitting vibration and unbalance stress and to the adverse effect of flange plate joint sealing, effectively guaranteed normal use and the Security of flange plate.
