The first drafting meeting of the standards of China Metrology Association "diaphragm of membrane gas meter" and "valve cover and valve seat of membrane gas meter" was held

the first drafting meeting of the standards of China Metrology Association "diaphragm of membrane gas meter" and "valve cover and valve seat of membrane gas meter" was recently held in Nanning, Guangxi. In this standard, we are eager to show our solid system expertise to customers in JEC exhibition. Jixie Gas Working Committee letter (2016) No. 06, the first drafting meeting of the association's standard t/cma-rq

China Metrology Association's standards diaphragm of membrane gas meter and valve cover and seat of membrane gas meter, actively organized and promoted by the gas meter working committee of China Metrology Association, has recently been held in Nanning, Guangxi

according to the zjxgwh (2016) No. 06 document, the projects of the association's standards t/cma-rq002:2016 membrane gas meter diaphragm and t/cma-rq03:2016 membrane gas meter valve cover and seat, which are actively organized and promoted by the gas meter working committee of the China Metrology Association, have been listed in the second batch of the association's standard formulation tasks in 2016, and it is planned to complete the standard formulation by the end of 2017

the meeting was presided over by sunxiaodong, deputy general manager of Dandong Thermal Instrument Co., Ltd., the editor in chief. Secretary General Wang Shunan of the China Metrology association made an important speech. Please pay attention to the changes in the volume of cooling medium caused by temperature. Secretary General Wang Shunan made a detailed description of the development status and development trend of the membrane gas meter industry. He pointed out that the membrane of the membrane gas meter, the valve cover and valve seat of the membrane gas meter are the core components of the membrane gas meter, which is crucial to the safety and performance of the gas meter, The drafting of this standard will be an improvement in the quality of products in the industry, which is of far-reaching significance to the future membrane gas meters, and it is necessary to change the proportional coefficient between force value and displacement. The revision process should be based on the principle of fairness and fairness, fully listen to the opinions and suggestions of all parties, and improve the drafting efficiency. At the meeting, Dongtao, Secretary General of the gas meter working committee of the China Metrology Association, put forward several requirements for the drafting work. He asked the participating units to implement the experimental verification work in strict accordance with the time node of the standard formulation plan in the drafting process of the standard, and master the first-hand data. The tensile testing machines can be roughly divided into pendulum tensile testing machines and electronic tensile testing machines, Provide strong data guarantee for the further deepening of relevant work. On the basis of fully considering the development of the industry, strive to formulate industry forward-looking Association standards. The meeting was attended by more than 40 expert leaders from nearly 30 enterprises and institutions. (according to the working committee of gas meters of China Metrology Association)
