Q:Can the stem and sphere of a ball valve be made into a whole? Did you do that? Seek specific analysis
Top mounted ball valve. The stem is joined to the sphere.
Q:What are the characteristics of the valve stem with the media?
See medium type, acid or alkaline, corrosion resistance, suitable for natural gas, oil or steam applicable valves, many kinds of ah, 2Cr13 304, 316, and so on,
Q:Pneumatic diaphragm control valve
Not necessarily, depending on the structural characteristics of the valve. In the case of constant pressure difference between the two ends of the valve, if the valve is quick to open, the flow is greater than 50%;
Q:What does the stem material VTA mean?
At the same time, it is subjected to the impact and corrosion of the medium, and it also causes friction with the packing. Therefore, in selecting the stem material, it must be guaranteed that it has sufficient strength at the prescribed temperature, good impact toughness, scratch resistance, corrosion resistance.
Q:The lift valve of the globe valve is not a single stem,
Here's a pictureA semicircle slot with a depth of 8 mm is placed on the semicircle ring slot, where the filling is placed. Valve has a road seal, the role is in the valve maintenance can be opened to the maximum, direct change filler.
Q:What is the cause of valve stem vibration in electric single seat control valves?
3, liquid medium through the valve, resulting in cavitation caused by shocks, higher frequency, usually accompanied by valve howling. High temperature large pressure difference, the use of single seat valve is relatively easy to happen, this is the control valve (valve body structure) type selection caused by improper,4, the valve core resonant frequency and pipe and fluid frequency consistent with the vibration caused by higher frequency, usually accompanied by pipe vibration. Change the valve at both ends of the process, valve opening may be eliminated.
Q:At the Beijing show, Hauck was able to understand the equipment
I just have one of their home equipment, is used to deal with the stem, my company is used before rolling, the effect is very good, there are lines, and later used their home equipment, the effect was not the same, very easy to mirror effect; and their home customer service service is also very timely. Service attitude is very good, our company is planning to buy a.
Q:Good or good red earthworm fishing rod
Red with no barbed hooks, and not save, a few days will be a large number of deaths, occasionally when working with earthworms is also good.
Q:How to adjust the valve stem valve leakage?
Connect the cylinder and the stem, screw down and lengthen the screw, it will not leak.
Q:What causes the stem to be stuck?
The key is the gap between the valve stem and the sleeve, especially when the temperature is too high, easily blocked; it also includes the stem shaft end clearance, valve plate and valve body clearance, valve stem sleeve lubrication, stem wear serious.
We have business of various commodities, development of valve parts, brand promotion and agency servicesMain products: valves, mechanical parts, carbon steel, alloy steel parts, castings, forgings, etc. Products are all exported.By virtue of the advantageous location, we have a well-established sales network.
