Q:Are there any problems with the horizontal installation of the pneumatic butterfly valve on the horizontal pipe? Is it serious?: Especially the butterfly valve pneumatic valve is generally installed vertically, horizontally mounted, the stem sealing effect of internal gravity packing layer, resulting in loose packing, the risk of leakage, and the pneumatic valve of the valve positioner will reduce the accuracy of adjusting clearance, cause.In addition, the butterfly valve sealing surface may also be deformed because of the stem deformation and wear.This is the danger, not necessarily be a problem, but the large-diameter valves such as DN150 or more dangerous, if you have a small caliber valve (butterfly valves are generally large, with a small caliber ball valve), will do some suggestions, safety, adjust the installation position.

Q:Can the stem fish where there is grass?: According to the common types of rods (divided into rods, sea rods, rod etc.) which is suitable for water in many places for fishing, I think is good pole operating point (point to catch nest form).

Q:If the valve stem in the 50% position of the whole trip, then the flow through the valve is also in the most large 50%?: Look at what the spool is, there are a variety of curve relations, look at the equipment demand flow, and work methods.

Q:Stem V type PTFE packing maximum pressure /?: The valve stem is a vulnerable part, and the mechanical performance and heat treatment performance of the material should be paid attention to when selecting.

Q:How many connections are there between the handwheel and the stem?: I don't understand. I've got some information for youThe simplest is: your home faucet is the valve.First, the definition of valve:"Valve" is defined in the fluid system, used to control the direction of the fluid, pressure, flow device. A valve is a device for flowing or stopping the medium (liquid, gas, powder) in a pipe and equipment and controlling its flow.Two, according to the role of opening and closing valves, valve classification methods are many, here describes the following.1. classification by function and use(1) cut-off valve: cut off valve, also known as closed circuit valve, whose role is to connect or cut off the pipeline medium. The cut-off valve includes gate valve, globe valve, plug valve, ball valve, butterfly valve and diaphragm.(2) check valve: check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class.(3) safety valve: the role of the safety valve is to prevent the pipe or device in the medium pressure exceeds the required value, so as to achieve the purpose of safety protection.(4): regulating valve regulating valves including control valve, throttle valve and pressure relief valve, and its role in the regulation of the medium pressure, flow parameter.(5) shunt valve: diverter valve, including a variety of distribution valves and traps, etc., its role is to distribute, separate or mix the medium in the pipeline.

Q:I would like to ask Shahe posted for fishing should lead the stem number weight set for the most suitable does not affect the effect of fishing, and everyone in Shahe is usually posted with what method of fishing, hook and hook the bottom? My younger brother is a beginner: it is easy to be corroded, the best use of dual phase steel, 20 alloy steel, alloy steel and zirconium C276 wood, but also to see the specific medium containing exactly what, these materials should be the cheapest dual phase steel

Q:What is the reason for the leaking of the stem of the open rod gate valve? How to solve?: 2. Solutions:A, tighten the packing bolt, increase the sealing surface performance.B, replacement of packing, pay attention to the correct choice of packing type, packing should be placed neatly placed, packing should be cut into 45 degrees, at the time of the joints should be staggered over 30 degrees, presses the packing, two bolts to tighten the synchronization, to prevent partial pressure.

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:Chlorine valve, valve stem, valve spool are selected what material is better?: In fact, ordinary carbon steel, but chlorine special valve sealing better, specific you can ask about the production of chlorine valve manufacturers, chlorine, many things are national standard parts, very good buy

Q:Hydraulic manifold valve, stem movement is a positive cover, what is the role?: Generally speaking, opening a small slot, that role is a bit like the proportion of valve opening meaning. Prevent shock and stabilize flow.
