A kind of balance flow meter with protective layer
Technical field
The present invention relates to a kind of balance flow meters with protective layer, belong to flow meter field.
Background technique
Balance flow meter is a kind of revolutionary differential pressure type flow instrument, is originated from U.S. space shuttle sustainer in 2003 Liquid oxygen flowmeter is surveyed, Traffic simulation Technology design and research and development are used by U.S. NASA.It waits Reynolds numbers, increase section using unique Part thickness and machining accuracy are flowed, makes mobile performance close to venturi, construction is still succinct, safe, but performance has qualitative leap, ingeniously Wonderful structure design can bring biggish stable differential pressure with lesser permanent crushing under the requirement of shortest straight pipe, realize high Precision measures steadily in the long term, will bring the revolution of differential pressure flowmeter.
Existing balance flow meter all parts structure connection causes to measure unstable lack there are unreasonable place It falls into.In addition, can cause to damage to balance flow meter inside when the liquid medium of measurement has corrosivity, balanced flow is reduced The service life of meter.
Summary of the invention
The technical problem to be solved by the present invention is to, provide a kind of structure securely, measurement stablize, it is easy to operate and have The balance flow meter with protective layer of anticorrosion ability.
In order to solve the above technical problems, the technical solution adopted by the present invention are as follows:
The both ends of a kind of balance flow meter with protective layer, including flowmeter supervisor, the flowmeter supervisor are equipped with method Orchid, the flange offer mounting hole along its border direction, and the flowmeter supervisor inner wall is connected with orifice plate, the orifice plate along Its border direction opens up hole, and the two sides that the orifice plate is located on the flowmeter supervisor offer pressure tappings, the flow It is connected with the fixed part being connected to the pressure tappings on meter supervisor, the top of the fixed part is connected to the lower end of media flow pipe, The upper end of the media flow pipe is provided with shut-off valve, and the upper end of the shut-off valve is communicated with two condensers of condenser Upper end is connected to three valve groups, and the upper end of three valve group is connected with transmitter.
Erosion resistant coating is coated in the flowmeter supervisor.
The material of the erosion resistant coating includes polytetrafluoroethylene (PTFE).
It is fixed between the transmitter and three valve group by screw bolt and nut.
The material of the orifice plate is stainless steel.
The number of described hole is 12, equidistant to arrange.
Beneficial effects of the present invention: a kind of balance flow meter with protective layer provided by the invention, flowmeter supervisor are upper Offer pressure tappings in the two sides of orifice plate, be connected with fixed part be connected to pressure tappings on flowmeter supervisor, the top of fixed part and The lower end of media flow pipe is connected to, and the upper end of media flow pipe is provided with shut-off valve, and the upper end of shut-off valve is communicated with condenser two The upper end of a condenser is connected to three valve groups, and the upper end of three valve groups is connected with transmitter, product structure securely, measurement stablize, It is easy to operate.It is coated with erosion resistant coating in flowmeter supervisor, the material of erosion resistant coating includes polytetrafluoroethylene (PTFE), by the setting of erosion resistant coating, It can be avoided corrosion of the measuring medium to flowmeter supervisor's inner wall, improve the service life of balance flow meter.
