- Q:I was wondering if someone could tell me the manufacturing date on this aircraft engine valve.
- Wow Hannah! That's a cool find for sure! It appears to be possibly a valve for a radial aircraft engine as it looks very similar to ones i've seen used in Pratt+Whitney R3350's etc. It looks like it could probably date to the 1940's up thru the 1950's. Look for a Part Number stamped on the valve or on the box. After WW2 there were all kinds of manufacturers making parts for airplanes. Many were gobbled up by competitors, converted to manufacturing other products or went out of business altogether. However, a few did hang on....and I think this may be what has become of Thompson Aircraft today.... Thompson Aerospace, Inc 22431 Antonio Parkway B160-102 Rcho Sta Marg, CA 92688-2804
- Q:The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,
- Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the opening or closing or adjustment; actuators have electric or pneumatic, and so on, through the transmission device to drive the stem, valve plate rotation;
- Q:How is the lug butterfly valve connected to the flange?
- Lug type butterfly valve is also called a single flange type, that is, with a flange on the valve body, usually installed at the end of the pipe, and even the method is 1: double bolt lock on the valve body 2: into the flange 3: lock nut
- Q:D37A1X9-16CB1: what does this butterfly valve mean?
- The model is composed of 7 units, the types of valves (gate valve Z, J, L, Q ball valve, throttle valve, check valve and H valve, butterfly valve, connection mode (D) internal thread 1 thread 2, welding flange 4, 6, 7, the clamp (0) electromagnetic transmission mode 1 solenoid valve, hydraulic, electric and hydraulic turbine are 2, 3, 4 and 5 gears, bevel gear, pneumatic hydraulic, 6, 7, 8, 9) pneumatic and hydraulic, electric, structure (straight or DC type 7,1 on behalf of the center plate, vertical type A (A) and LT X9) on behalf of a sealant is heat-resistant rubber, kg 16 kg, C represents the body material of carbon steel WCB, B1 on behalf of the valve plate is made of ductile cast iron plating)
- Q:How to use the fire butterfly valve properly?
- Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements
- Q:Transformer butterfly valve and pressure relief valve difference
- The oil immersed transformer pressure release valve is a safety device installed in the transformer, when the internal pressure is less than the limit value of the transformer such as 35kPa, which is in closed state, when the transformer internal fault occurs, a large number of transformer oil by pyrolysis, produce large amounts of gas, the internal pressure of the oil tank increased dramatically when the opening pressure exceeds the pressure release valve when the pressure relief valve opens, the internal oil and gas overflow, to release the pressure, avoid the pressure on the inside of the lead tank cracking or permanent deformation, when the fault of transformer internal end, internal pressure tank to reduce pressure release valve closing pressure, it will automatically shut down to prevent outside air enter the inside of the tank or water.
- Q:When will Butterfly Valves be used?
- Butterfly valve has the advantages of simple structure, easy operation, small footprint and light weight;1, for the city water supply network in general, DN300 still DN300 valve, butterfly valve above, this installation is convenient (especially large diameter valve installation is inconvenient, the weight of large volume, big);2, there are sediment pipeline, such as powder, mud and other mixed substances;
- Q:What is the difference between turbine butterfly valve and flanged butterfly valve?
- The worm gear is the driving mode and corresponds to the handle; the flange is connected and corresponds to the clamp. Flange worm valve is generally, the handle of the butterfly valve
- Q:How can I get the fire signal butterfly valve?
- 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 the handwheel worm gear to the disc to open and close and adjust the flow to the handwheel clockwise rotation for the valve closed. 3, worm gear is arranged in the box body micro switch has 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, the quasi it shows the state of the valve switch. B, in the driving 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.
- Q:Does the pneumatic butterfly valve need electricity?
- Pneumatic butterfly valve generally not need steam can Shandong Yuhong automatic control valve
