Q:CAD drawing of butterfly valve
Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.
Q:What are the classification criteria for pneumatic butterfly valves?
The channel of the valve body inner surface smooth, fluid resistance, high CV value, strong circulation, moderate torque, the use of four seal structure and elastic rubber gasket seat with SI in high temperature aging on the outside sealing surface, zero leakage medium.Pneumatic butterfly, characteristics, there is a slit leaving the valve seat, the product is suitable for use in poor air circulation environment.The pneumatic telescopic butterfly valve is characterized in that the novel and reasonable design, unique structure, light weight, convenient operation, open and close rapidly; in addition to the telescopic valve for regulating and throttling effect, compensation pipeline temperature generated by thermal expansion and contraction function, but also for the installation of valve replacement and maintenance convenience. The sealing parts can be adjusted, replaced, sealed, reliable and so on.
Q:What's the difference between D71X-16 and D71H-16 butterfly valves?
Model D71X model means this, D represents butterfly valve, 7 represents butterfly connection form for clip type connection, 1 represents straight through, and 16 represents pressure 16 kg pressure.X stands for sealing and soft sealing, and the sealing surface is usually nbr.H stands for metal hard sealing, usually 2Cr13 surfacing.D71X-16 butterfly valve featuresIts main features are:1 、 the design is novel, reasonable, unique structure, light weight, fast opening and closing.2 、 small operating torque, easy operation, labor-saving and smart.3. It can be installed and maintained conveniently in any position.4, seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.5, sealing materials aging resistance, corrosion resistance, long service life and so on.
Q:Gate valve, butterfly valve and so on can do the valve so that?
Valve can not be used to adjust the use, if the switch can not be in place, the medium flushing gate valve is easy to cause poor sealing!
Q:Function of signal butterfly valve in fire sprinkler system
The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
Q:Are fire fighting signal valves and signal butterfly valves the same thing?
The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.
Q:What kind of butterfly valve is sd342x?
Sd342x: two-way double eccentric soft sealing butterfly valveS: two way pressureD: butterfly valve3: turbine operation4: flange connection2: double eccentricX: rubber sealProbably the shape is not so good in appearance,Double eccentric mostly elastic sealThree eccentric is multi-layer sealHope to be of help to youOpened valve Co., Ltd. on the production of butterfly valve
Q:Why anti condensation of aluminum alloy anti condensation butterfly valve?
Anti condensation butterfly valve principle: the use of the high performance plate material, can effectively prevent the temperature of body parts, isolating the transfer medium in the pipeline, to the actuator and the connecting flange surface without dew.
Q:Import electric butterfly valve which brand is more reliable?
Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
Q:Where is the PCV valve?
pcv valve is on the valve cover closest to the firewall.it is attached to a rubber hose that runs to the intake. right below an electrical plug
