Q:It is different from the butterfly valve butterfly valve
Butterfly valve is clear that the butterfly, because it is so called as valve plate, butterfly valve.
Q:Read your answer, about pneumatic butterfly valve solenoid valve selection
This is our company's products in Pucheng clean energy Co., Ltd. successful use case, if you need case details, you can give me a QQ number, I sent you. In addition, I suggest you add a pneumatic control valve, so that the safest, no map, I can give you. Saved is to look at the project site, if the north, the electromagnetic valve is recommended to use the 1/2 aperture, and a gas control valve or 1/4, it can guarantee the opening speed of the valve, special attention is on the use of the electromagnetic valve chain, this is very important, I will be the general experience specific issues to deal with specific, can not copy blindly, in most cases, this is no problem. And 1/4 also to see traffic, is also 1/4 solenoid valves, flow valve with big caliber is not the same, is not the same, the 1/4 path from the 2mm-12mm range, the CV value is small, about 0.1, with a large amount of 1.2, has big gap, valve opening time is also a great gap, to distinguish between the.
Q:What are the uses and classifications of manually operated clip butterfly valves?
In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees -90 degrees between, when rotates to 90 degrees, the valve opens the card completely. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.
Q:Electric butterfly valve (not take the lead) what do you mean?
Electric butterfly valve, as its name implies, consists of an electric actuator and butterfly valve, and the customer does not take the lead, that is, without the electric actuator, only the butterfly valve can be provided.
Q:Should I connect the butterfly valve before and after the pump? Or gate valve?
1, valve, the fluid resistance is small, the sealing surface by the erosion of small and medium Chong brush. 2, opening and closing more effort. 3, medium flow unrestricted, no disturb, do not reduce pressure. 4. The shape is simple, the structure length is short, the manufacturing technology is good, and the scope of application is wide. Butterfly valve main deficiency is that it uses the pressure and temperature range is small. And poor sealing. Therefore, the gate valve should be preferred.Gate valve (gatevalve) is a gate valve used to open and close parts, and along the vertical axis of the valve seat movement, in order to achieve the opening and closing action of the valve. The valve can only be fully open and fully closed, opening and closing parts is the gate, the direction of motion perpendicular to the direction of the fluid, valve two square I-shaped sealing surface forming the wedge, the wedge angle varies with the valve parameters, usually 5 degrees is not high, medium temperature is 2 degrees 52'. Improve the process of valve, make up the sealing surface angle in the process of production deviation, this kind of gate is called flexible gate.
Q:What do you mean by manual butterfly valve DN100 D341X-10?
DN100 refers to the inside diameter of the butterfly valveD stands for butterfly valves3 represents the turbine drive4 represents the flange connectionThe 1 represents straight throughX is the representative of the Dengqen rubber seal10 represents the pressure of 1.0Mpa (10 kg)Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe 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. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.
Q:What's the use of fire butterfly valve?
Its working principle is as follows:1, the signal butterfly drive by the worm gear drive shaft and butterfly plate rotation, realize the opening and closing and control flow.2, rotating worm gear drive handwheel, so that the butterfly plate to open and close and adjust the flow of purpose, hand wheel clockwise rotation for the valve closed.3. The worm gear drive box is equipped with micro switches in two forms:A, in the gear box body is provided with open and close direction two microswitches, respectively, when the valve fully open and close action, connected to the control room "valve open" valve off "light source, to accurately display the switch state of the valve.B, the transmission device is arranged in the box body the microswitch (disc position close to 0 degrees), when the butterfly plate from 0 degrees to 40 degrees when the position of a micro switch, the output valve closed signal, 40 degrees to 90 degrees when the position of another pair of normally closed output valve opening signal. A cam that adjusts the touch microswitch and shows the different positions of the disc.The fire in the fire that is the switch signal butterfly valve in the pipe network, because the fire pipe water must be kept clear, so as to ensure the timeliness of fire, so the signal valve once closed, will tell the host signal module alarm, fire control network notify the monitoring center is closed.
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:whats the name of that valve under the kitchen sink?
Hi There I installed a valve with a t-type handle for my refrigerator's ice maker. This is a saddle type valve which is place on a water line and taps into the water inlet . It has a piece of rubber around the needle valve so it will not leak. If there is no plastic or copper line protruding from the line then it should lead to an ice maker. Now I have seen the same type of valve which was placed on the water line and then hooked up to the dishwater. Either way don't mess with it unless it leaks... Why the pipe it is attached too will have to be replaced. Been there done that check out the two links below
Q:How much is the Honeywell butterfly DN300?
Find the agent or find a reliable valve plant a lot of foreign brands are in Chinese OEM so find a reliable factory is relatively good service to keep up
