Z941y-16c is the most widely used valve type. It is very popular because it has small friction between sealing surfaces during opening and closing, relatively durable, low opening height, easy to manufacture and easy to maintain. It is suitable for medium and low pressure, and for high pressure. The principle of closing is that the sealing surface of the pressure head and the sealing surface of the valve seat are closely matched to prevent the medium from flowing.
Electric high pressure gate valve z941y-16c
Dimensions:
2 in - 36 in. (DN50 - dn900)
Pressure: 600Lb - 2500lb
Material: carbon steel, stainless steel, etc
Connection mode: butt welding, flange, etc
Sealing form: parallel door or wedge door
Valve advantages:
1. The pressure self tight sealing structure is adopted, elastic plunger is adopted, and the welding joint is used at both ends of branch pipe.
2. the sealing surface of the valve seat is plasma spray welding of cobalt based cemented carbide. The wear resistance and scratch resistance of the sealing surface of the valve are hardened and nitrided.
3. the valve stem surface is treated with corrosion inhibitor nitriding, which has good corrosion resistance and scratch resistance.
4. the opening and closing of the valve is controlled by electrical equipment. The electric device is equipped with special motor, reducer, torque control mechanism, field operation mechanism, hand, electric switch mechanism, and can be operated remotely in addition to local operation.
Technological process advantages:
1. the shell is forged and cast by two processes, which are smooth and clean in appearance, uniform in structure and in accordance with the requirements of high temperature and high pressure; a full series of full forged steel gate valves can be provided according to the requirements of users;
2. Special materials are matched to ensure high hardness and hardness of sealing surface; precision grinding, smooth as mirror, wear-resistant, corrosion-resistant, and effectively prolong service life;
3. Back seal design, effectively protect the sealing packing and prevent air leakage;
4. Multi channel testing, such as high pressure water strength, high pressure gas strength and non-destructive testing, to comprehensively control the quality of pressure components;
5. The valve stem surface is precision ground, hardened, scratch resistant, corrosion resistant, effectively reducing opening and closing torque, and the operation is more convenient;
6. Special corrosion resistant packing structure design is adopted, temperature resistant and pressure resistant, no corrosion, automatic lubrication, reducing open and closing friction, avoiding corrosion on the valve stem surface, thus avoiding leakage;
7. the design of two-way pressure seal meets the demanding requirements of various special conditions;
8. strictly carry out manual supporting research to ensure that the sealing degree of double-sided sealing surface reaches more than 90%, and realize the air bubble level factory sealing test;
9. Z60 series unique stamping elastic groove design, which can automatically compensate machining error, adapt to high temperature conditions and avoid occlusion; z62y series adopts double gate design, and the indenter automatically corrects machining error, and keeps 100% matching degree of sealing surface. It is particularly convenient for on-site maintenance and maintenance;
