NB/T47017-2011 pressure vessel sight glass, also known as stainless steel equipment sight glass, stainless steel flange sight glass. It is a kind of stainless steel used to observe the change of medium in chemical, petroleum, oil refining, food, cosmetics, medicine and other industrial equipment containers. glass. The operator adjusts or controls the medium according to the situation displayed by the pressure vessel sight glass, so as to ensure that the medium in the vessel is always within the normal range to ensure the safety of production and the quality of the product.
In addition, liquefied gas storage tanks, tank trucks, gas-liquid reactors, reaction kettles and other containers need to be equipped with pressure vessel sight glasses to prevent accidents due to overfilling or unbalanced material reactions due to overfeeding.

Overview of Wafer Connection Lift Check Valve
Wafer double flap check valve The H76X type wafer check valve produced by our factory is composed of valve body, valve flap, valve stem and spring, etc., which are connected by a wafer. Due to the short closing stroke of the disc and spring loading, water hammer can be significantly reduced. The valve is mainly suitable for water supply and drainage pipe networks in cities, industries and high-rise buildings. Because its structure length is shorter than that of general check valves, it is most suitable for places with limited installation space.
Product Features of Wafer Connection Lift Check Valve
1. Small size, light weight, compact structure and convenient maintenance
2. The valve plate adopts a dual type, which can be quickly closed under the elastic force of the spring.
3. Due to the quick closing effect, the medium can be prevented from flowing back
4. The length of the valve body structure is small and the rigidity is good
5. Safe and convenient, can be used for horizontal and vertical installation

X49H-16C cock glass plate level gauge
【Overview】
The X49H-16C glass tube level gauge is an intuitive liquid level measuring instrument, which can be installed on a boiler or other pressure vessel to directly indicate the liquid level of the measured medium.
[Working Principle and Structural Features]
The upper and lower plug valves of the instrument are welded with flanges to connect with the container to form a communicating device, and the liquid level in the container can be directly read through the glass plate. And can clean and replace the glass tube without stopping the furnace. When the glass tube is accidentally damaged, use the handle to turn the plugs of the upper and lower stopcock valves through 90° to prevent the medium in the container from continuing to flow out. The bottom of the level gauge is equipped with a drain valve, which is used to discharge the remaining liquid and clean the interior during maintenance.
【The main technical parameters】
Working pressure: ≤1.6Mpa
Working temperature: ≤200℃
Nominal diameter DN: 20, 25
Flange sealing surface type: RF
Applicable medium: non-corrosive medium such as water, oil, steam, etc.
