Q:How do hydraulic butterfly valves work?
3. butterfly valve hydraulic drive device structureThe valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. A section of optical axis is arranged at the end of the driving shaft and is inserted into the end of the manual shaft (matched with the clearance of H11/ H11), and the function is that the manual shaft is concentric with the main drive shaft. In normal operation, the optical axis rotates with the drive shaft, but the manual device does not move. When the hydraulic operation is performed manually or manually from the hydraulic unit, a * * * conversion is required. The utility model is composed of a nut, a hand wheel, a screw rod, a support frame and a shifting device. When the utility model is switched, the hand wheel is rotated and driven by the screw rod to move. A guide rod is arranged on the bracket to make the shift and translation stable.
Q:Butterfly valve, two-way pressure and one-way pressure what is the difference?
The positive pressure and the reverse pressure, the pressure when the medium returns
Q:What is the D37-10Q butterfly valve?
It may be the D371, the turbine to the clip type soft sealing butterfly valve, from your model can also see that the pressure is 1.0MPa, the body is ductile iron. It could be the D373, the turbo clamp hard seal butterfly valve, which is more expensive than the soft seal.
Q:I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve
Water should be off to the sink is the stop valve off
Q:butterfly valves d7a1x5
D- valve type (butterfly valve), 7- connection mode (to clamp), A- valve shape mode (A), 1- structure form (vertical plate), X5- valve seat sealant species (Ding Qing, NBR)
Q:Where are the exhaust valves, mud valves and butterfly valves?
Chemical plant with colloid, puffed agent and granule. Wine industry, paper industry. Butterfly valves are used in petroleum, chemical, food, pharmaceutical, textile, water and electricity, ships, urban water supply and drainage, smelting, and energy systems as regulating and intercepting devices.
Q:Butterfly valve is the control valve?
The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
Q:How many kinds of butterfly valves are there?
Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.[structure]The utility model is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a butterfly plate.
Q:Gate valve and butterfly valve which is installed when there is a direction?
Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.Butterfly valve refers to the closure of parts (butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually 90 degrees butterfly simple structure, small volume and light weight, only by a few parts. Moreover, the utility model can be rapidly opened and closed only by rotating 90 DEG, and the operation is simple.Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, gate valve advantages: fluid resistance is small, opening and closing more effort, medium flow unrestricted, not disturbing flow, do not reduce pressure.
Q:What do you mean, handle, butterfly valve, hard back and soft back?
Hello, soft sealing butterfly valve is generally divided into skeleton, seat and frameless valve seat, the skeleton of the general material: resin, aluminum, iron.. Etc.. With back seat is on the back of the vulcanized rubber, without skeleton, valve seat is rubber.
Having one group of outstanding managerial talents and veteran technicians, the company has been bringing in the multi-strip overseas high-tech valve production assembly line.In this way, we powerfully enhance the production's efficiency. And the annual production quantity amount to more than 250,000 pcs.The main product is the Butterfly valve, Gate valve, Check valve, Y-strainer Ball valve Globe valve and so on. We can produce various valves according to the standards of GB, JB, ANSI, DIN, API, JIS and so on and also we can provide according to clients demand and requirement.
