For the orifice flowmeter, it is now a kind of equipment for each large and small coal mine. For this product, you know how it is used and installed? The following is to provide use information and installation information.
The use of orifice flowmeters:
Orifice flow meters are used to determine the gas flow in a gas drainage line. When the gas passes through the orifice through the orifice plate, the flow rate will increase and a pressure difference will be generated on both sides of the orifice plate, and there is a constant relationship between the flow rate and the pressure difference. Through the pressure difference, the gas flow in the pipeline can be calculated.
Orifice flow meter installation:
1. Orifice plate flowmeter has orifice plate, take pressure nozzle and steel pipe. During the installation process, attention should be paid to the installation direction of the orifice plate, as shown in the figure.
2. Orifice plate installation requirements
(1) The length of the measuring tube on the upstream side of the orifice plate is 10D, and the length on the downstream side is 4D.
(2) The surface of the measuring tube must be clean, free of sinks and deposits, and the relative roughness K/D
Should be less than or equal to 0.001.
(3) The length of straight pipe required on the orifice plate must not be less than the following requirements:
(4) The roughness K/D of the inner surface of straight pipe sections other than the measuring pipe length is less than or equal to 0.001.
(5) When the orifice plate is installed in the measuring tube, the circumference of the opening is limited to the coaxial axis of the measuring tube, and the end face on the upstream side of the orifice plate is perpendicular to the axis of the pipe, and the verticality is less than ±1%.
These are the data for the use and installation of orifice flowmeters. Dear friends, do you understand? If you do not understand, you can contact me directly. According to the occurrence of coal mine accidents nowadays, it is professional to produce this kind of non-powered product and no artificial high-tech products.

A pigment is a substance that can stain an object. Pigments can include many products, we mainly supply lithopone. It is used as a base for lake pigment and used as a inert pigment for paint, ink and cosmetics as well as in a large range of applications in plastic industry.
. It is used as a filler in paper, leather, and linoleum.
Lithopone B301 is our regular exporting product. We are the main supplier in the north of China.
