Technical Field
The utility model relates to the technical field of flowmeters, in particular to a high-sealing orifice plate flowmeter.
Background
In the industrial setting, meters that measure fluid flow are collectively referred to as flowmeters or flowmeters. Is one of the most important meters in industrial measurement. With the development of industry, the accuracy and range of flow measurement are increasingly required, and various types of flow meters are sequentially developed to adapt to various purposes, so that the flow meter is widely applied to industries such as petroleum and natural gas, petrochemical industry, water treatment, food and beverage, pharmacy, energy, metallurgy, pulp and paper, building materials and the like.
The flow metering is widely applied to various fields of industrial and agricultural production, national defense construction, scientific research on external trade and people's life. In the petroleum industry production, from petroleum exploitation, transportation, smelting and processing to trade sales, the flow measurement runs through the whole process, and any link is not separated from the flow measurement, otherwise, normal production and trade interaction of the petroleum industry cannot be guaranteed. In the chemical industry, inaccurate flow metering can cause imbalance of chemical component distribution ratio, product quality can not be guaranteed, and serious production safety accidents can also occur. In the industrial production of electric power, measurement and regulation of medium flow rates of liquids, gases, vapors and the like are important. The accuracy of flow measurement not only has great economic significance for ensuring the power plant to operate under the optimal parameters, but also becomes an important link for ensuring the safe operation of the power plant along with the development of high-temperature high-pressure large-capacity units. Such as interruption or reduction of the instantaneous feed water flow to a large capacity boiler, can cause serious dry or pipe explosion accidents. This requires that the flow measuring device not only meter accurately, but also send an alarm signal in time. In the steel industry, the flow measurement of circulating water and oxygen (or air) during steelmaking is one of the important parameters to ensure product quality. In the industries of light industry, food, textile and the like, the flow metering is not separated.
The prior orifice plate flowmeter is mostly sealed by adopting a bolt fastening mode when in use, but the sealing mode can cause leakage after long-time use.
