Description
Technical field:
The present invention relates to a kind of Flange joint interpolation type L-type seal ring and using method thereof, belong to the technical field of joint seal of flanges.
Background technique:
Seal ring, in Flange joint, has important meaning to the raising sealing of Flange joint and the steadiness of connection.The structure of existing seal ring is disc-shaped, in the work progress of Flange joint, existing seal ring is by the restriction of self structure, easy sideslip in use, need installer with hand steered live seal ring, such installation process poor stability, workman is careless slightly will jam a finger, and waste time and energy, affect construction speed and sealing effect; And the sealing effect of conventional seals circle does not often reach usage requirement.In addition, in use, seal ring easily misplaces or tears due to long-time large load operation mounted flanged joint, and working life is short, affects the stability of flanged joint, adds maintenance cost.
Having a kind of magnetic gasket on the market, self there is magnetic in seal ring, can be adsorbed on flange to be connected in use, it is dangerous that this kind of flange can solve construction to a certain extent, the problems such as sideslip, but this kind of magnetic gasket manufacture cost is high, and be only applicable to metal flange.
Summary of the invention:
For the deficiencies in the prior art, the invention provides a kind of Flange joint interpolation type L-type seal ring, this interpolation type L-type seal ring Security is high, and it is firm to seal, long service life; And this interpolation type L-type seal ring is not by the restriction of flange material, applied widely.
The present invention also provides a kind of using method of above-mentioned interpolation type L-type seal ring.
Technological scheme of the present invention is as follows:
A kind of Flange joint interpolation type L-type seal ring, comprises the socket and washer portion that are connected as a single entity; The radial cross section of described interpolation type L-type seal ring is L-shaped.Described socket in use, is inserted in flange connections by interpolation type L-type seal ring of the present invention, for retaining washer, makes its not easily sideslip dislocation in installation process, effectively can accelerate construction progress, time saving and energy saving, improves construction safety.
Preferred according to the present invention, described socket external diameter and flange inner diameter adapt.The socket that socket external diameter is identical with Flange joint bore, inserts in flange connections by socket during use, and improve the tightness degree that socket is connected with flange inner diameter, further fixed seal ring, makes it not easily misplace in installation process and come off.
Preferred according to the present invention, the outer side surface of described washer portion is provided with the ring-type small embossment coaxial with described washer portion, and the height of described ring-type small embossment is 1mm-10mm.Ring-type small embossment improves the frictional force between surface of contact between washer portion and surface of contact, can improve the sealing effect of Flange joint.
Preferred according to the present invention, the number of described ring-type small embossment is 1-10.
Preferred according to the present invention, described interpolation type L-type seal ring is quality of rubber materials or silica gel material.Quality of rubber materials or silica gel material seal ring make seal ring when ensureing also have certain elasticity when having higher-strength, improve the stability and seal that connect.
A using method for above-mentioned Flange joint interpolation type L-type seal ring, its step is as follows:
(1) flange connections that preparation two is to be connected, inserts described interpolation type L-type seal ring socket in a flange connections, and makes described washer portion and flange contact;
(2) two flange connections to be connected are bolted.
Preferred according to the present invention, when being bolted flange in step (2), each bolt rotates 2-3 week and fastening next bolt, and each bolt carries out, until bolt is all fastening successively according to clockwise or sequence counter-clockwise.Clamping bolt can make in Flange joint process in this way, and parallel flange connects, and ensures tightness and the stability of connection.
Preferred according to the present invention, a kind of using method of above-mentioned Flange joint interpolation type L-type seal ring, also comprises step (3) and beats flange surrounding, according to the order clamping bolt again of step (2).To beat after flange clamping bolt again, the whole flange of whole guarantee, whole seal ring and each clamping bolt uniform force can be made, improve bolted stability and sealing.
Advantage of the present invention is :-
1, interpolation type L-type seal ring of the present invention in use, described socket inserted in flange connections, for retaining washer, no longer need manually to fix cushion rubber, just can ensure not easily sideslip dislocation in installation process, effectively accelerate construction progress, time saving and energy saving, improve construction safety;
2, interpolation type L-type seal ring of the present invention, overcomes the drawback that magnetic cushion rubber can only be applicable to metal flange connection, can be used in the Flange joint of various material, applied widely, and structure is simple, cheap;
3, interpolation type L-type seal ring of the present invention, in use described socket is inserted in flange connections, play the effect of fixed seal ring, the seal ring slippage that can effectively prevent from seal ring in the course of the work causing because working pressure is large, misplace or tear, substantially prolongs the working life of seal ring.
4, interpolation type L-type seal ring of the present invention, can adopt the nitrile rubber, urethane rubber, polypropylene rubber, silicone rubber, fluorine rubber, butyl rubber, ethylene propylene rubber, neoprene etc. that society generally uses all can meet its demand.And Applicable scope of the present invention is except except metal flange, be also applicable to plastic pipe flange, as PVC, PE, PPR flange joint.
