Oxygen stop valve
Other Products
I. Introduction:
The JY41W oxygen stop valve, a special valve for oxygen pipelines, is designed based on the operation characteristics of oxygen pipelines and the flammable and explosive nature of oxygen medium, with the design principles of safety, reliability and superior performance. Valve type: According to the "Several Technical Regulations for Oxygen Pipelines in Iron and Steel Enterprises" issued by the Ministry of Metallurgical Industry, stop valves are adopted. The main body is made of stainless steel or copper alloy with excellent flame retardancy; the sealing surface is the base metal or surfacing with D802; other internal parts are made of stainless steel or copper alloy; the transmission part is lubricated with non-flammable grease, and is marked with obvious oil-prohibited signs. Structurally, the bracket is fully enclosed, equipped with an electrostatic conduction device, and the valve stem is fitted with a dust cap. Since its launch in the market, our company's special valve for oxygen pipelines has been widely trusted by large and medium-sized steel plants, oxygen production plants and petrochemical plants for their oxygen pipeline networks!
II. Product Features:
1. Flame and fire resistance: The main components are made of copper alloy, which is a non-flammable material. Even if it collides with solid particles in high-speed airflow, no sparks will be generated. Therefore, this valve has flame and fire resistance performance.
2. Safety and reliability: This valve is equipped with dust-proof, water-proof and oil and sewage-proof devices. All valve bodies in contact with oxygen have undergone strict degreasing and oil-prohibiting measures before assembly. The packing material is polytetrafluoroethylene, which can ensure safety and reliability during use.
III. Structural Features:
1. For nominal pressure PN≥1.6MPa and DN125~200, an inner bypass structure is adopted; for DN250~500, a structure with an outer bypass valve is adopted. The purpose is to reduce the pressure difference between the front and rear of the valve, avoid high flow velocity, high erosion and high temperature generation, thus ensuring the safe operation of the oxygen pipeline network and reducing the operating torque at the same time.
2. Medium flow direction: For PN≥1.6MPa and DN≤100, the medium flows from below the valve disc to above the valve disc; for DN≥125, the medium flows from above the valve disc to below the valve disc. For valves with DN≥125, the medium adopts the flow direction of "high inlet and low outlet", which on the one hand meets the structural requirements of the inner bypass valve, and on the other hand, due to the effect of medium pressure, the closing force of the valve is greatly reduced.
3. This valve is equipped with an electrostatic conduction safety device, which can avoid sparks caused by static electricity.
4. Compared with ordinary stop valves, the bracket part of the oxygen pipeline stop valve adopts a fully enclosed structure, and the protective cover on the bracket can be opened when tightening the packing, which plays the role of oil and dust prevention. It also has obvious oil-prohibited signs.
5. All parts have undergone strict degreasing treatment.
