Features
1.Threaded outlet of upper body is convenient for connection with the inlet of flow meter of fueling machine.
2.High temperature pressure relief valve is used to relieve the pressure increasing with the temperature of oil in the pipeline due to the cutoff of cutting ring and  close of auxiliary valve when oiling machine breaks down.
3.(Normally open type) auxiliary valve can stop oil reverse flowing and leaking when it is closed.
4.The holder can make auxiliary valve normally open to reduce the resistance of oil flow and that will not affect its flux.
5.Spring is used to strengthen sealing performance when auxiliary valve closes.
6.Cutting ring is cut off under stress and ensures the cutoff moment of 350~550N·m.
7.Main valve is used to close the oil flow to oiling machine from submerged oil pump.
8.Main body is made of HT200 cast iron and inside or outside threaded inlet is for your option.
9.Testing jack is used to test the pressure in pipeline after being installed with a pressure meter.
10. Tumbler is a holder to keep main valve normally open. Using special alloy Galaxy 1# can ensure the normal action under  75 oC.

Fluorocrystalline mica, also known as Fluorphlogopite Mica, synthetic mica, artificial mica, synthetic mica crystal, belongs to the silicate type artificial mica crystal, is under the high temperature condition of 1500°C, through strict process conditions and material ratio, in platinum The mica crystals smelted in the yttrium have a chemical formula of KMg3(AISi3O10)F2(OH)-, and do not contain (OH)-. The (OH)-hydroxyl group is replaced by F-(fluoro), which is similar to the fluorite mica. Materials commonly used in the general industry are natural mica. Natural mica is an underground ore naturally formed and belongs to the class of silicates. Most of the industrial mica used is phlogopite (brown) and muscovite. Its ideal chemical formula is KAI2(AISi3O10)(OH)2. OH)-(Hydroxy), due to the presence of hydroxyl (water molecules), its performance in all aspects is far lower than that of fluorocrystalline mica.

The main characteristics of fluoride crystal mica:

1, high temperature: can work long-term in the 1100 °C environment.

The testing department of the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences (nationally recognized testing institute) tested the thermal weight loss of 8% at 1100°C for 48 hours, and the melting and devitrification temperature was 1375°C.

2. Electrical insulation: The volume resistivity is 10 times higher than natural mica. Electrical breakdown strength is PTFE

Lean 10 times.

3, hot and cold blasting stability is very good

5 cycles of -40°C~70°C at the 5th Saibao Lab of the Ministry of Information Industry

Inspection, all qualified.

4, anti-corrosion:

Fluorophlogopite does not react with acid and alkali solutions, and does not react with water. Under the long-term (2 to 3 years) scouring of high-temperature and high-pressure water (including acid and alkali), the original clarity and transparency can still be maintained.

5, high frequency performance:

The dielectric constant of fluorite mica is 4.6 ε, and the dielectric loss is (1~4)×10 −4 tg δ, and the dielectric loss is very low. And because of the pure texture, all parameters are extremely stable.

6, optical properties

Since the fluorite mica contains less impurities, its light transmittance is compared from infrared to ultraviolet.

High, the transmittance is close to 100%.

7, Mosaic (Mosaicity):

The Mosaicite of fluorocrystalline mica is less than 0.25 degrees, which was produced in the experiment.

The neutron flame is not high enough to absorb multi-band light beams and is an ideal neutron monochromator test material.

8, vacuum deflation performance:

The evaporative volume of fluorite mica is low, and it is measured with a mass spectrometer and the trace gas released is only

O2, N2, Ar and other adsorbed gases. Since the H2O vapor is not released, this is extremely valuable for use as an electrical vacuum insulation material, which can greatly increase the service life of the vacuum device.

9, excellent physical properties:

Fluorocrystalline mica has atomicity flatness, transparency, separability and elasticity, not aging

It is not brittle and so on.

Due to the high temperature resistance, corrosion resistance, low frequency loss, and high bulk resistivity

Absorb multi-band light beam, excellent light transmittance and other advantages. Therefore it has become an ideal new material in the high-end area.

Fluorocrystalline mica Available in:

In the range of 180mm×53mm or ∮76mm, it can be processed into various shapes according to user requirements. Thickness within the range of 0.02mm~1.0mm can be allocated according to user requirements. The conventional thickness is 0.04~0.2mm.
