Abstract
The utility model discloses an external flange for gas table, including the connection pad that has the middle part through -hole, the connection pad is two segmentation hierarchic structures, and rotatable cover is equipped with the flange on the tip pipeline section of connection pad, and inside being formed with of pipeline section is used for passing in and out the screw hole that gas hickey spiral shell closed with the gas table, and the screw hole diameter is greater than middle part diameter of hole, and the screw hole bottom is formed with annular platform, and the main aspects of connection pad constitute the axial positioning shaft shoulder is used in flange butt joint installation. Preferred, the fender that is equipped with restriction flange drunkenness on the tip pipeline section of connection pad encircles, it comprises circlip for the axle to keep off the ring, being equipped with on the main aspects periphery wall of connection pad and being used for pulling its pivoted moment of torsion transmission structure, this moment of torsion transmission structure comprises a plurality of radial inserted bar blind holes. The beneficial effects of the utility model are that, the screw thread interface converting with the gas meter that can be convenient is the flange interface, and simple structure, convenient to use, and firm in connection.
Description
Technical field
This utility model patent relates to a kind of gas meter, flow meter attachment structure, a kind of plug-in flange for gas meter, flow meter.
Background technology
Gas meter, flow meter is the instrument of metering user gas consumption, and the outer-type of gas meter, flow meter mainly has threaded and two kinds of structures of Flange joint.Flange joint is mainly used in the pipeline that gas consumption is bigger, and gas meter range is relatively big, and threaded is generally used for the pipeline that gas consumption is less, and corresponding gas meter range is less.But the two does not has obvious demarcation line, at certain gas consumption or the gas meter of corresponding range, flange both can be used, it would however also be possible to employ screw connection structure.After generally the connected mode at pipeline determines, need to select corresponding gas meter in this way.But the restriction that this selection is supplied by existing gas meter, because Flange joint gas meter manufacture process is relatively complicated, manufacturing cost is slightly higher, it usually needs customize in advance, there is the deficiency that can not meet demand in time.For this reason, it may be necessary to the attachment structure of existing threaded gas meter is improved, to meet the needs of two kinds of connected modes.
Summary of the invention
The purpose of this utility model is aiming at the deficiencies in the prior art, it is provided that a kind of plug-in flange for gas meter, flow meter.This plug-in flange is connected with the pipeline of Flange joint by flange, and connection dish is connected with having threaded gas meter, so that threaded gas meter to be converted to flange white silk level gas meter, so that threaded gas meter has screw thread and two kinds of types of attachment of flange.
For achieving the above object, this utility model adopts the following technical scheme that.
A kind of plug-in flange for gas meter, flow meter, including the connection dish with middle through-hole, connection dish is two-part hierarchic structure, flange rotatably it is set with on the little end tube section of connection dish, inner tube segment is formed with the screwed hole for screwing togather with gas meter, flow meter turnover gas hickey, screwed hole diameter is more than middle through-hole diameter, is formed with ring-shaped platform bottom screwed hole, and the big end of connection dish constitutes described flange abutting joint with axially positioning the shaft shoulder.
Use this utility model of preceding solution, connection dish is used for threadeding of the air inlet/outlet with gas meter, flow meter, flange is used for and the Flange joint on gas supply pipeline, so that threaded gas meter is connected with the fuel gas pipeline of Flange joint easily, wherein, the front end large end face of connection dish forms sealing surface.Therefore, no matter Gas Pipe is threaded or Flange joint, all can be connected with threaded gas meter by this plug-in flange.Its simple in construction, easy to connect, strong adaptability.And after on the large end face of connection dish front end, sealing gasket is set, it can be ensured that connection dish forms excellent sealing with gas meter joint, it is ensured that sealing therebetween；It addition, flange is rotating annexation with being connected dish, when being fuel gas pipeline Flange joint, the bolt position of distribution on its circumference can be adapted to easily, further ensure that easy to connect, reliable.
Preferably, the little end tube section of described connection dish is provided with the baffle ring limiting flange play.After being installed on gas meter, in accumulating, installation process, flange is formed temporary support and stop, make between flange and gas meter housing, to keep a determining deviation, it is to avoid damage gas meter.
It is further preferred that described baffle ring is made up of circlip for shaft.Can direct purchased parts commodity, it is not necessary to processing and manufacturing, improve production efficiency, reduce manufacturing cost.
Preferably, the big end periphery wall of described connection dish is provided with for pulling its torque transfer arrangement rotated.With by this torque transfer arrangement pull its rotate, it is ensured that connection dish and gas meter joint formed firm, be reliably connected, and holding connection dish big end seal face integrity.Torque transfer arrangement therein includes the decorative pattern of rolling, straight burr, and flat, four directions or six sides, or the hole etc. of grafting boosting-rod.
It is further preferred that described torque transfer arrangement is made up of multiple radial direction inserted link blind holes.Inserted link blind hole is used for inserting boosting-rod to pull connection dish.Further ensure that that does not injure connection dish when pulling holds greatly seal face.
The beneficial effects of the utility model are, easily the threaded of gas meter can be converted to Flange joint, its simple in construction, and gas meter is easy for installation, and is connected firmly, reliably.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, but the most therefore this utility model is limited among described scope of embodiments.
See Fig. 1, a kind of plug-in flange for gas meter, flow meter, including the connection dish 1 with middle through-hole, connection dish 1 is in two-part hierarchic structure, rotatably being set with flange 2 on the little end tube section of connection dish 1, inner tube segment is formed with the screwed hole 1a for screwing togather with gas meter, flow meter turnover gas hickey, and screwed hole 1a diameter is more than middle through-hole diameter, being formed with ring-shaped platform 1b bottom screwed hole 1a, the big end of connection dish 1 constitutes described flange 2 abutting joint with axially positioning the shaft shoulder.
Wherein, the big end periphery wall of connection dish 1 is provided with multiple inserted link blind hole 1c；The little end tube section of connection dish 1 is provided with the baffle ring 3 limiting flange 2 play, and this baffle ring 3 is made up of circlip for shaft.
Preferred embodiment of the present utility model described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should be in the protection domain being defined in the patent claims.
