Installation note points of orifice bimetallic thermometer

1 measuring gas and steam: gas pressure in the upper pipe; Liquid pressure on the side of the mouth but not in the right, of sedimentary particles can block the take pressure; The pressure in the tube side steam words, OPY magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

2. Direction of orifice plate, label & other; +” For positive, & other; - ” As a negative, & other; +” Is in the direction of fluid to come over. OPY magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

3. Take the positive and negative pressure mouth of guide pipe under any circumstances to keep parallel; OPY magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

4. Orifice plate is generally going to cooperate with differential pressure transmitter, pressure guide tube connected to the differential pressure transmitter when must pay attention to the negative pressure don't put wrong, & other; H” As is, & other; L” Negative; OPY magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

5. Advice from the top of the pipeline gas differential pressure measuring device, the liquid on the lower part of pipeline, measuring steam if there is one with the cooling tank, should maintain the cooling tank on the same horizontal height.

6. If it is a straight pipe requirements, shall be counted according to the calculation orifice throttling device, has calculated the installation requirement of orifice plate, and straight pipe length, second can also according to the former 20 d after 10 d to pack ( D refers to the orifice diameter) OPY magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

when installation should satisfy at least according to flow to the top 10 D after 5 D, D refers to the workers according to the diameter of orifice plate, such as DN500, namely the orifice flow direction is 5000 mm, flow direction is 2500 mm.

through strict check test, the user can be at ease use after purchase. The bimetallic thermometer has many application fields, all of the single phase flow can be measured, a part of the miscible flow can also use the product. Can't accurate measurement because of two phase flow, perhaps even a water hammer phenomenon, damage the pipe fittings. If use circular orifice, condensate can run off from the edge of annular orifice, this product the minimum flow surface is close to the tube wall of circle, with minimal standard orifice flow surface is in the center of the pipe concentric circles. The impurity in the fluid flow rate is low, the general flow is close to the wall edge, appear constantly and popularization and application of new varieties of the throttle device, the throttle device matching with differential pressure transducer and display instrument has been developing rapidly in terms of performance and quality. Widely used in petroleum, chemical industry, metallurgy, electricity, heating, water supply in areas such as process control and measurement. Orifice bimetallic thermometer have been widely used in coal, chemical industry, transportation, construction, textile, food, medicine, agriculture, environmental protection and People's Daily life and so on each domain of national economy, is the development of industrial and agricultural production, save energy and improve the quality of our products and improve the economic benefit and the management level of the important tools in the national economy occupies an important position.
