The model and specifications of the instrument precision pressure gauge are unified with national standards

In the instrument model representation: Y means pressure, Z means vacuum or damping, J means precision or rectangular, A means ammonia meter, X means signal or electrical contact, XC means magnetic auxiliary electrical contact, P means diaphragm, E means diaphragm , F means corrosion protection, N means shock resistance, T means spring tube, B means stainless steel and so on.
We often use: YTF means stainless steel pressure gauge, YA means ammonia pressure gauge, YXC means electrical contact pressure gauge, YC means vacuum pressure gauge, Y means vacuum pressure gauge, Y means acetylene pressure gauge, and YO. Means heat resistant pressure gauge, YH means hydrogen pressure gauge, etc.
YQ and YQF series two-stage pressure regulators are mainly suitable for analytical instruments, environmental protection instruments, power industry, and other instruments and equipment that require precise control and adjustment of input pressure. They are also suitable for non-corrosive (YQ series) or corrosive (YQF series) pure gas and standard mixed gas, after precise adjustment of the high-pressure gas source of the cylinder gas, the main technical parameters of the instrument and equipment are sent:
1. Model and parameters Technical parameters / Model YQ-1 YQ-2 YQ-3 YQ-4 YQ-5 YQF-1 YQF-2 YQF-3 YQF-4 YQF-5
Input pressure gauge range (Mpa) 0 ～ 25 0 ～ 25 25 0 ～ 25 0 ～ 25 0 ～ 25 Output pressure gauge range (Mpa) 0 ～ 0.6 0 ～ 0.16 0 ～ 4 0 ～ 0.25 0 ～ 1 Pressure gauge level 2.5 2.5 2.5 2.5 2.5
Input pressure (Mpa) ≤ 18.5 ≤ 18.5 ≤ 18.5 ≤ 18.5 ≤ 18.5 Output pressure (Mpa) ≤ 0.45 ≤ 0.12 ≤ 3 ≤ 0.2 ≤ 0.75 Rated flow rate (m3 / h) 0.6 0.06 0.6 0.2 0.2 0.6
2. Stability: The pressure of the air source is in the range of 5-15MPa, and for every 1MPa change in inlet pressure, the change in outlet pressure is not greater than 7 * 10-4MPa
3. Flow characteristics: when the inlet pressure is greater than 2 MPa, the regulated flow changes within the rated range, and the output pressure does not change more than 6% of the upper limit of the output pressure gauge measurement.
4. Installation and connection:
a. Inlet end: G5 / 8 "(left and right hand), W21.85 14 teeth (left and right hand) b. Outlet end: M10 * 1; M8 * 1 hose connector, etc. Three, adapt to gas: YQ series
