Description

High pressure carbon steel is seamless flange
Technical field
The utility model is related to flange manufacturing technology field, more particularly to a kind of seamless flange of high pressure carbon steel.
Background technology
Steel high pressure seamless pipe, high-pressure boiler tube are one kind of boiler tube, belong to seamless steel pipe classification.Manufacture method with it is seamless Pipe it is identical, but to manufacture steel tube place steel grade have strict requirements.Often in high temperature and high pressure when high-pressure boiler tube is used Condition, high-pressure boiler tube is mainly used to manufacture superheater tube, reheater tube, wireway, the main steam of high pressure and superpressure boiler Pipe etc..
, it is necessary to be attached using to flange in steel high pressure seamless pipe connection procedure, flange generally comprises in disk form Ring flange, the side of described ring flange is connected with the cylindrical neck portion for being connected with circular pipe.Flange is in connection During, in the connection procedure of steel high pressure seamless pipe, when being vibrated by the external world, easily produce and rock, in vibration processes In, so that sealing is not tight.
Utility model content
The utility model is in order to overcome deficiency of the prior art, there is provided a kind of seamless flange of high pressure carbon steel, on the one hand Transverse sealing effect can be improved, is on the other hand easy to improve longitudinal sealing performance.
The utility model is to be achieved through the following technical solutions:
A kind of seamless flange of high pressure carbon steel, flange carbon steel forging and stamping are made, and on high-pressure seamless pipeline, it includes Flange disk body in disk form, and it is connected with the circle for being connected with high-pressure seamless pipeline in the side of described flange disk body Cylindrical neck, and the cylindrical neck portion and the seamless connection of flange disk body, in described flange disk body away from cylindrical neck portion The transverse annular seal groove for being provided with sealing gasket is offered on end face;And offered on the end face of described flange disk body Annular groove;And longitudinal annular seal groove for being provided with sealing gasket is offered on a wall of the annular groove.
Preferably, offered for installing along the centerline direction of flange disk body on the wall surface of the annular groove The bolt hole of bolt, bolt hole is extended on the end face of flange disk body, and the quantity of the bolt hole is four, and is evenly distributed On the end face of the flange disk body.
Preferably, described cylindrical neck portion and ring flange body phase connecting end surface are symmetrical space curve.Flange disk body When being connected with high-pressure seamless pipeline, both intersections are space curve, by the connection end of the cylindrical neck portion for connecting Face is arranged to the shape of intersection, easy to connect.
Preferably, described transverse annular seal groove and the section of longitudinal annular seal groove are rectangle.
Compared with prior art, the beneficial effects of the utility model are:The utility model is by being provided with transverse annular Seal groove, sealing gasket is provided with transverse annular seal groove, it is possible to increase its horizontal sealing effectiveness, is prevented because of transverse-vibration It is dynamic, cause sealing not tight;By being provided with longitudinal annular seal groove, and sealing gasket, energy are installed in longitudinal annular seal groove Its longitudinal sealing effectiveness is enough improved, is prevented because of extensional vibration, cause sealing not tight.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state figure of the present utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain The utility model, is not used to limit the utility model.
It is structural representation of the present utility model to refer to Fig. 1 and Fig. 2, Fig. 1;Fig. 2 is use state of the present utility model Figure.
A kind of seamless flange of high pressure carbon steel, flange carbon steel forging and stamping are made, and on high-pressure seamless pipeline, its Including flange disk body 1 in disk form, and it is connected with for being connected with high-pressure seamless pipeline in the side of described flange disk body 1 The cylindrical neck portion 2 for connecing, and the cylindrical neck portion 2 is seamlessly connected with flange disk body 1, in described flange disk body 1 away from circle The transverse annular seal groove 3 for being provided with sealing gasket is offered on the end face of cylindrical neck 2;And in described flange disk body 1 End face on offer annular groove 4;And offered for being provided with sealing gasket on a wall of the annular groove 4 Longitudinal annular seal groove 5, described transverse annular seal groove 3 and the section of longitudinal annular seal groove 5 are rectangle.
Offered for installation bolt along the centerline direction of flange disk body 1 on the wall surface of the annular groove 4 Bolt hole 6, bolt hole 6 extended on the end face of flange disk body 1, and the quantity of the bolt hole 6 is four, and is evenly distributed On the end face of the flange disk body 1.
Described cylindrical neck portion 2 contact surface that is connected with flange disk body 1 is symmetrical space curve.Flange disk body 1 and height When pressure seamless pipeline is connected, both intersections are space curve, and the connecting end surface of the cylindrical neck portion 2 for connecting is set The shape of intersection is set to, it is easy to connect.
In the utility model, antirust oil or solderable paint are scribbled on the surface of flange body 1 and cylindrical neck portion 2.
The utility model is provided with sealing gasket by being provided with transverse annular seal groove 3 in transverse annular seal groove 3, Its horizontal sealing effectiveness can be improved, is prevented because of oscillation crosswise, cause sealing not tight;By being provided with longitudinal annular seal groove 5, and sealing gasket is installed in longitudinal annular seal groove 5, it is possible to increase its longitudinal sealing effectiveness, prevent because of extensional vibration, Cause sealing not tight.
As shown in Fig. 2 the flange is used cooperatively with another ring flange, high-pressure seamless pipeline can be effectively installed, can Prevent it from producing the not tight phenomenon of sealing.
Preferred embodiment of the present utility model is above are only, is not used to limit the utility model, it is all in this practicality Any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
