Product Description

Product Description

Onn Self Production Wj41h Flange Connection Bellows Globe Valve for Petroleum Application
1. The key component of the bellows sealed globe valve is the metal bellows. The lower end is automatically welded to the valve stem assembly, and the upper end is automatically welded to the connecting plate to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem.
2. The valve disc adopts a conical design, and the sealing surface is streamlined with the medium, resulting in better sealing performance and longer service life.
3. Dual sealing design (bellows+packing): If the bellows fails, the valve stem packing will also avoid leakage and comply with international sealing standards.
4. The valve cover comes with a grease fitting, which can directly lubricate the valve stem, nut, and shaft sleeve, unlike traditional methods that only lubricate the threads.
5. Ergonomic design handwheel, with a longer service life, easy and convenient operation, and safer and more reliable.

FAQ

Q1:what is the safety valve ?
1. The main purpose of safety valves is to protect life, property and the environment. A safety valve is designed to open and release overpressure in a container or device, and to re-close and prevent further fluid release when it returns to its normal state.
2. A safety valve is a safety device that is in many cases the last line of defense. It is important to ensure that the safety valve can operate at all times and under all circumstances. Safety valves are not process valves or pressure regulators and should not be abused. It should be run for one purpose only: overvoltage protection.

Q2:How does a Safety Valve work?
The working principle of a safety valve can be summarized as follows:
1. Open: When the system pressure exceeds the set pressure of the safety valve, the valve disc opens under the action of medium pressure and spring force, releasing pressure.
2.Keep open: When the system pressure stabilizes within the set pressure, the spring stabilizes, the system remains under stress, and the safety valve remains open.
3. Close: When the system pressure is lower than the set pressure of the safety valve, the spring cannot lock and seal, and the valve disc closes under the action of medium pressure, and the medium pressure no longer increases.
