Embodiment

[0042] F4 lining process:

[0043] 1. The production of F4 tube:

[0044] The pipe is prefabricated by the equal pressure method, and the surface of the hose is oxidized.

[0045] Second, the treatment of the front guide tube of the lining:

[0046] 1. Treatment of the diversion tube: Derust the inside of the diversion tube with a wire brush, and wipe it clean with xylene. There should be no oil pollution.

[0047] 2. Treatment of F4 tubes: first check the surface and oxidation treatment of F4 tubes, and those that cannot meet the requirements will be reworked; those that are well oxidized are cleaned with xylene, and there is also no oil pollution and a fluorinated coating on the surface.

[0048] 3. F4 is pressed into the guide tube:

[0049] 1. After the two are cleaned, mix AB glue (504), and evenly coat a layer on the inner wall of the diversion tube.

[0050] 2. In order to consider the shrinkage rate of the F4 tube and the reliability of the product, it should be en...

Abstract

The invention discloses a metal pipe float flow meter tube lining processing technique, and is characterized in that: taking F4 as raw material, employing two-step method processing technique, processing into lining hose in the first step and pressing the lining hose into metal drainage tube in the second step, then turning to form; finally, cutting and processing the formed pipe fitting in a conventional method to form the finished products. The invention has simple manufacturing technology, low molding condemnation factor of only 5%, the thermal expansion coefficient approaching to metal and will not break in application due to the effect of the operating environment.

Description

technical field [0001] The invention relates to a flowmeter, in particular to a processing technology for the liner of a flowmeter guide pipe. Background technique [0002] The selection of the lining material of the metal tube rotameter body and the reasonable selection of the manufacturing process will directly determine the price, performance and service life of the meter body. The tube body of the metal tube rotameter in the prior art is lined with F46 and PFA materials, the realization process is complex, and the requirements for process temperature, pressure, cooling and exhaust are relatively high. In the compression molding process, it is difficult to avoid the defects of pores, cracks, uneven thickness, and non-melting particles. Due to the complex process, the scrap rate of the metal tube float body can reach 18%. According to customer feedback information, due to the temperature change of the measurement medium, the expansion coefficient of F46, PFA and the metal...
