Abstract
The invention discloses a gas meter provided with external flanges. The gas meter comprises a gas meter body in threaded connection, wherein a gas inlet and a gas outlet of the gas meter body are connected with the external flanges in threaded fit manner respectively; the external flanges are provided with connecting disks with middle through holes; each connecting disk adopts a two-stage type step structure, a pipe section at a small end of the connecting disk is rotationally sleeved and connected with a flange, the pipe section is connected with a gas pipe of the gas meter body through a threaded hole, the diameter of the threaded hole is larger than that of the corresponding middle through hole, an annular platform is formed at the bottom of the threaded hole, an annular sealing pad is arranged between the annular platform and the threaded connection front end of the gas meter body, and a large end of the connecting disk constitutes an axial positioning shaft shoulder for butting connection of the flange. Preferably, an elastic check ring for limiting play of the corresponding flange is arranged on the pipe section at the small end of each connecting disk; multiple radial rod inserting blind holes are formed in the outer circumferential wall of the large end of each connecting disk. The gas meter has the benefits that threaded interfaces of the gas meter are changed into flange interfaces conveniently, and the gas meter is simple in structure, convenient to mount, high in adaptability and firm to connect.
Description
Technical field
Patent of the present invention relates to a kind of gas meter, flow meter syndeton, particularly a kind of gas meter, flow meter with plug-in flange.
Background technology
Gas meter, flow meter is the instrument of metering user gas consumption, and the outer-type of gas meter, flow meter mainly contains and is threaded and Flange joint two kinds of structures.Flange joint is mainly used in the larger pipeline of gas consumption, and gas meter range is comparatively large, and is threaded and is generally used for the less pipeline of gas consumption, and corresponding gas meter range is less.But the two does not have obvious separatrix, at the gas meter of certain gas consumption or corresponding range, both can adopt flange, also can adopt screw connection structure.Usually, after the connected mode of pipeline is determined, need to select corresponding gas meter by which.But this selection is subject to the restriction of existing gas meter supply, and because Flange joint gas meter manufacture process is relatively complicated, manufacturing cost is slightly high, usually needs to customize in advance, there is the deficiency that can not satisfy the demands in time.For this reason, need to be improved the syndeton of the existing gas meter that is threaded, to adapt to the needs of different connected mode.
Summary of the invention
Object of the present invention is exactly for the deficiencies in the prior art, provides a kind of gas meter, flow meter with plug-in flange.This gas meter, flow meter by arranging plug-in flange in the import and export of gas meter, this plug-in flange is connected with the pipeline of Flange joint by flange, terminal pad with there is the gas meter be threaded be connected, being threaded, gas meter is converted to Flange joint gas meter, thus the gas meter that makes to be threaded has screw thread and flange two kinds of selectable types of attachment, its applicability is strong.
For achieving the above object, the present invention adopts following technical scheme.
A kind of gas meter, flow meter with plug-in flange, comprise the gas meter, flow meter be threaded, the air inlet of described gas meter, flow meter and gas outlet are connected with plug-in flange respectively by threaded engagement, this plug-in flange is provided with the terminal pad with middle through-hole, terminal pad is two-part staircase structure, on the little end tube section of terminal pad, rotating being set with is connected with flange, pipeline section is connected with the tracheae of gas meter, flow meter by threaded hole, threaded hole diameter is greater than middle through-hole diameter, ring-shaped platform is formed bottom threaded hole, this ring-shaped platform is threaded between front end with gas meter, flow meter and is provided with sealing ring pad, the large end of terminal pad forms the described flange abutting joint axial location shaft shoulder.
Adopt the present invention of preceding solution, terminal pad being threaded for the air inlet/outlet with gas meter, flow meter of plug-in flange, flange for the Flange joint on gas supply pipeline, so that the gas meter, flow meter be threaded is connected with the fuel gas pipeline of Flange joint easily.Therefore, no matter fuel gas pipeline is threaded or Flange joint, all can be connected with gas meter of the present invention.Its structure is simple, easy to connect, strong adaptability.And after sealing gasket is set on the large end face of terminal pad front end, can guarantees that terminal pad and gas meter joint form excellent sealing, guarantee sealing therebetween; In addition, flange and terminal pad are rotating annexation, therefore, when being fuel gas pipeline Flange joint, can adapt to its bolt position circumferentially distributed easily, guarantee easy to connect, reliable further.When the connection on fuel gas pipeline is for being threaded, removes plug-in flange, and directly adopting being threaded of gas meter.
Preferably, the little end tube section of described terminal pad is provided with the baffle ring of restriction flange play.To form temporary support and stop to flange in accumulating, installation process, make between flange and gas meter housing, to keep a determining deviation, avoid damaging gas meter.
Preferably, described baffle ring is made up of circlip for shaft.Can direct purchased parts commodity, need not processing and manufacturing, enhance productivity, reduce manufacturing cost.
Preferably, the large end periphery wall of described terminal pad is provided with the torque transfer arrangement of rotating for pulling it.Rotate to be pulled it by this torque transfer arrangement, guarantee that plug-in flange and gas meter pass in and out gas interface and formed and firmly, be reliably connected, and the integrality of the large end seal face of maintenance terminal pad.Torque transfer arrangement wherein comprises decorative pattern, the straight burr of roll extrusion, and flat side, four directions or six sides, or the hole etc. of grafting boosting-rod.
Preferred further, described torque transfer arrangement is made up of multiple radial inserted link blind hole.Inserted link blind hole is for inserting boosting-rod to pull terminal pad.
The invention has the beneficial effects as follows, gas meter, flow meter is converted to Flange joint by being threaded easily, and its structure is simple, and gas meter is easy for installation, strong adaptability, and is connected firmly, reliably.
