Today I will introduce a national invention authorized patent-a gas turbine flow meter core assembly. The patent was applied for by Ningbo Chuangsheng Instrument Co., Ltd., and the authorization was announced on January 25, 2017.
Content descriptionThe utility model relates to a flow meter, in particular to a meter core assembly of a gas turbine flow meter.
Background of the inventionThe gas turbine flowmeter is mainly used for the flow measurement of air, nitrogen, oxygen, hydrogen, biogas, natural gas, steam and other medium fluids in industrial pipelines. When measuring the volume flow of working conditions, it is almost independent of the fluid density, pressure, temperature, viscosity and other parameters. Impact. Gas turbine flowmeters are more suitable for occasions where the flow rate varies greatly than differential pressure flowmeters. Its wider range ratio can reduce the diameter of the measuring tube to a certain extent and reduce the investment. With the development of natural gas measurement technology and the increasing requirements for natural gas trade and transfer measurement, gas turbine flowmeters will gradually be used in natural gas flow measurement. At the same time, due to the low density of natural gas, how to further simplify the structure of the turbine flowmeter, simplify the installation of the turbine flowmeter, and further improve the sensitivity of the turbine flowmeter is an important topic in the research and development of the existing turbine flowmeter. The gas turbine flowmeter detection element has a complex structure, high manufacturing cost, low accuracy, low sensitivity and short service life.
Summary of the inventionThe technical problem to be solved by the utility model is to provide a gas turbine flowmeter meter core assembly with simple and compact structure, low manufacturing cost, high precision and sensitivity and long service life.
The utility model provides a gas turbine flow meter watch core assembly, which includes a watch core support 1, a rotating shaft 4 and a signal plate 402. The watch core support is provided with a shaft hole 103, and the rotating shaft rotates through a bearing. Is installed in the shaft hole, and both ends of the shaft extend outside the shaft hole, the head of the shaft is provided with a connecting part 401, the signal plate is fixed at the tail of the shaft, and The side wall of the watch core support is provided with a refueling passage 104, the refueling passage is branched into branches 1042 with the same number as the bearing, the outlet end of the branch faces the bearing, and the end of the refueling passage is matched The oil pipe 105 is installed.
Further, the watch core support includes a disc body and a support body that are connected to each other, the shaft hole is opened on the support body and extends to the disc body, and the shaft hole is connected to the The disc body is coaxial, and a gland 2 capable of pressing the bearing is fixed on the disc body. There are two bearings and they are respectively installed at both ends of the shaft hole. The connecting part is a threaded body or a prism with a regular polygonal cross section. The side wall of the watch core support is provided with a recessed hole, the bottom surface of the recessed hole is provided with the refueling channel, and a sealing ring is provided between the inner wall of the recessed hole and the outer wall of the oil pipe. The rotating shaft includes a first rod body, a second rod body, and a third rod body connected in sequence, and the diameter of the second rod body is larger than the diameters of the first rod body and the third rod body.
The beneficial effects of the present invention are that the gas turbine flowmeter meter core assembly of the utility model has a simple and compact structure, convenient and quick assembly, low manufacturing cost, high operation accuracy and sensitivity, and long service life.
The mirror wire are used for car recorder and car backing radar.
