Abstract

Then utility model discloses a compact double-sided flange, which is provided with a central through hole, an upper end surface and a lower end surface; in addition, the double-sided flange is cylindrical, and notches are circumferentially arranged on the outer side of the double-sided flange; the ends of the notches sequentially and alternately run through the upper end surface and the lower end surface; and the upper end surface and the lower end surface are shaped like blades, and are provided with connecting holes. The compact double-sided flange has a simple and compact structure, is convenient to mount, is highly applicable and suitable for operation in narrow spaces, can be effectively connected with equipment in different forms of flanges, and can greatly save material cost.

Description

A kind of compact type Double-face flange

Technical field

The utility model relates to the pipeline connection technology field, relates in particular to a kind of Double-face flange.

Background technique

Flange (Flange) is flange plate or flange disk again, is to make pipe and the interconnective part of pipe in pipe end; This outward flange also is used for equipment to be imported and exported, and two equipment (parts) is coupled together, as the speed reducer flange.Simple flange is the plate-like plectane that has only a mating face, its casting (forging) be welded on pipe or parts on, and process jointing end face, flange and wear the through hole that bolt is used.

Other has a kind of flange with two mating faces, is referred to as Double-face flange, and two end face respectively connects the equipment (parts or pipe) with different connection sealing surfaces.As the Chinese patent publication number is the disclosed Double-face flange of CN2689032Y, has a trapezoidal sealing surface and a groove sealing surface, terminal device is coupled together to wearing bolt by direct employing.The prerequisite of this connection is that the terminal device both sides must have enough spaces bolt is passed.And this Placement is not suitable for the connection that flanged surface on the terminal device has the equipment of different flange shapes, and is in different size such as quantity, size or the flange in hole, also is not suitable for the connection that flanged surface on the terminal device has tapped hole.

In addition, also have a kind of flange, can satisfy the demand that connects equipment with different flange shapes with two mating faces.This Double-face flange is formed (see figure 1) by the connecting body of two flanged plates and a cylindrical shape or other shape, and the flanged plate on its both sides is connected with the flanged surface of two equipment respectively, by connecting body two equipment is linked up.The Double-face flange of this structure exists following technological deficiency:

(1) volume ratio is bigger, and occupation space is many, often only is applicable to the installation environment that the space is abundant.Under the narrow space environment,, be difficult to pass bolt or operating nut owing to be subjected to the restriction of two end flange.For example, when bolt must be worn toward equipment one side by an end flange in the middle of connecting body, hindered by the other end flange and be difficult to operate, the length that need to increase connecting body this moment just can be implemented.

(2) when being used for the connection of motor and driving mechanism thereof, the axle of transmitting torque will extend in the equipment, maybe needs to set up coupling, has increased cost and has reduced the reliability of using.

(3) parts such as motor, speed reducer are far away apart from the distance of supporting surface, and the moment of flexure that part is born increases, and has increased the stress of part.

The model utility content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple and compact for structure, be convenient to install, Double-face flange that applicability is strong, connect with the equipment of the different form of flanges of effective realization.

The purpose of this utility model is achieved by the following technical programs:

A kind of compact type Double-face flange that the utility model provides has central through bore, upper-end surface and lower end surface; In addition, described Double-face flange is cylinder type, and its outer side surface is circumferential row and is furnished with the notch position; Described notch position with an end alternately penetrate in the upper-end surface successively, the lower end surface; Described upper-end surface, lower end surface are blade profile, and it is provided with attachment hole.

The utility model is divided into the blade profile that staggers by the setting of notch position with upper-end surface and lower end surface.Like this, its pairing the other end of the attachment hole of an end is a vacancy, is not therefore stopped when placing bolt, and is easy to operate.Attachment hole can be through hole or tapped hole, and form that can be uniform or not uniform is arranged, to adapt to different form of flanges.

In the such scheme, the shape size of notch described in the utility model position is identical or staggered identical.The edge of central through bore is provided with male-female seal contact face on described upper-end surface and the lower end surface.

The utlity model has following beneficial effect:

(1) compare with the flange that prior art has two attachment faces, the utility model compact structure, volume is little, and whole cylindrical shell is the notch shape, makes the consumption of materials of flange and has alleviated weight thereby saved.

(2) the set notch position of the utility model greatly facilitates the operation that places of bolt, has significantly improved the convenience of installing.With need compare from the flange that the inboard inserting bolt of equipment is installed, use the utility model at dress, do not need the resolving device miscellaneous part when tearing open, install very conveniently, and can be used for the very little equipment in inner space.Compare with the flange of a trifle connecting body with that need install from equipment outside inserting bolt, promptly middle, in narrow space, it is very flexible to use the utility model to install, can not be subjected to the restriction and the obstruction of flanged surface position, two ends, the phenomenon of passing bolt or being difficult to operating nut can not occur being difficult to.

(3) dwindled the distance of parts such as motor, speed reducer, thereby reduced the moment of flexure that part bears, reduced the suffered stress of part apart from supporting surface.
