Q:How does the positioner output change when the feedback lever of the positioner and valve stem falls off?
The positioner and the control valve are connected with the feedback rod to fall off, and the positioner has no feedback and becomes a pneumatic amplifier with high magnification. If the positioner is positive, that is, the signal increases, the output also increases, then the stem fell off, the output run the maximum, and if it is counterproductive, then run zero.
Q:Zhejiang Zhiyuan stem
The distance between East and West, Zhejiang and North and south is about 450 kilometers. According to the second national land survey results, Zhejiang land area of 101 thousand and 800 square kilometers, 1.10% of the country, is China's smallest province, one of the [1].Zhejiang is the birthplace of Wu Yue culture and Jiangnan culture, and is one of the birthplaces of ancient Chinese civilization.
Q:What does the stem material VTA mean?
Valve stem: the valve stem is not only moving parts, force components, but also seals when the valve is opened and closed.
Q:Hello, the valve material is 3Gr13, stem 3Gr12, I would like to ask, this valve against sulfur?
3Cr13 martensitic stainless steel, C content is relatively high, if the S is dry, corrosion resistance is relatively small, with 3Cr13 not what big problem, if the water is single, cannot use 3Cr13,
Q:When the valve is mounted on a horizontal pipe, the ball valve stem
To the first party to do, or as requested, the handle is not down, easy to pass the acceptance. Operation is inconvenient, can add chain wheel or add operation platform.
Q:How about valve stem with 660?
If the action is not very frequent, the condition is not very complex, harsh, it should still be possible. Heat treatment will be better
Q:River fishing rod or sea pole?
Personally think that the sea river fishing rod selection slightly soft good side of the main said: when the raft River Fishing Raft rod slightly harder because the river water flow slightly soft mouth bar when eating is not obvious I river fishing have not used the following 100 currents 150 lead lead times 100 meter put much still qualify if you can't find it a hard rod slightly slightly in front of several section of soft cut this is not the way because due to an accident when the wire rod slightly off the four section later used when the degree of soft river fishing just slightly soft rod for the raft in the pond with a 20g ~50g lead is enough because there is no water effect slightly more soft signal more sensitive rod
Q:What is the difference between the upper valve stem bearings of the thrust bearings?
Its force direction is not the same, the general bearings are radial force, and the thrust bearing is in the end direction of the force, the solid structure is not the same."And you ask" thrust bearings, upper stem bearings what is the difference? / / thrust bearing, stem bearing difference"
Q:What is the cause of valve stem vibration in electric single seat control valves?
Single seat control valve stem vibration causes are many, there are common:1, the response time of the regulating system coincides with the response time of the regulated object, resulting in system shock, when the shock frequency is low, and the input signal of the control valve is also synchronous shock. The magnification of the system, such as the parameters adjusted by PID, can be removed by changing the parameters.Coincidence response time
Q:The ball valve in the valve is in what state is open
The switch of the ball valve is 90 degrees angle (except the three pass) and the slot is limited.
