Special ball valve for liquid ammonia - FHDQ liquid ammonia loading arm ball valve
Abbreviation: Liquid ammonia valve
Model: FHDQ-1000WOG-0080P
Overview of liquid ammonia ball valve:
FHDQ Liquid ammonia loading crane tube ball valve adopts the German all silica sol precision casting process. After solution annealing, it ensures high performance and can withstand more strength pressure. Japan Daikin carbon fiber sealing material, with more outstanding wear resistance, pressure resistance and temperature resistance. American API 607 fireproof and anti-static standard design.
Technical parameters of loading arm ball valve for liquid ammonia:
1. Valve body material: 304316316L
2. Diameter and specification: DN15~DN100
3. Service temperature: - 50 ℃~120 ℃
4. Application pressure: PN1.6 ～ PN4.0MPa
5. Drive mode: manual, electric, pneumatic
Liquid ammonia loading arm ball valve The floating ball design is adopted, which has the characteristics of reducing the operating torque and extending the service life. The sealing valve seat design ensures that the torque is reduced while maintaining a two-way sealing effect. The outer diameter of the elastic valve seat is provided with a pressure relief groove, which can reduce the fluid pressure passing through the inlet end, and at the same time, it has a good preload to ensure low-pressure vacuum sealing.
Design standard of special ball valve for liquid ammonia:
1. Design and manufacture: GB/T12237
2. Structure length: GB/T-12221
3. Wall thickness standard: GB/T-26640
4. Welding mark: GB/T-9115.1
5. Thread standard: ASMEB1.20.1
6. Clamp mark: ISO2852
Liquid ammonia special ball valve spool is precision machined and mirror polished to ensure zero leakage. It also has additional safety features. A small hole is added in the ball and valve stem groove to keep the pressure between the valve chamber and the fluid medium balanced when the valve is in the fully open position.
Liquid ammonia valve uses the valve stem which is installed inside the valve chamber. The design of the blow proof valve stem increases the safety protection coefficient. The valve stem is made of 316 material, and the double "D" structure connects the ball and the operating mechanism. The valve stem and the ball are precisely matched, which has the characteristics of bearing heavy loads. The unique butterfly elastic gasket design provides a movable loading type, so that the valve stem seal can be automatically adjusted to a balanced position to adapt to temperature changes and daily wear. The stem thrust bearing and thrust washer are primary seals, that is to say, reverse seals, which can reduce torque and prevent seizure. The adjustable V-shaped packing seal ring can produce multiple seals between the stem and the valve wall. The combined PTFE packing is composed of three to four rings, which has long service life, creep resistance and cold flow resistance.
