- 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: 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: 1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.
- First: Wat make you tinkling that the zone is bad? Every zone cooperate with 2 other essential parts: thermostat and power supply, In 90% of my carea, people firs go with their thinking to zone, but only 10% was realy zone. The first thing to check is termostat and power. you could do this very simply by removing termostat wire and tickling them together several times, if they have spark, than the most prabably is just thermostat broken
- Q: The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30
- 1, this is a good question, it seems that this has not yet made a unified standard requirements, a bit confused2, personal understanding of fire water supply pipe, pipe shall be installed on the valve, because the valve is fully open all closed features of fire control system is usually required is fully open, easy management features are obvious.3, fire water supply system is also useful to butterfly valve, but mainly signal butterfly valve.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: How warm is the PTFE butterfly valve?
- The normal temperature can be kept at 120 degrees and the instant temperature is 150
- Q: For example, the arrow above is from left to right, and the direction of my current is from right to left. Is that ok? I have a diameter of 700 of the hard seal butterfly valve is so installed, but it will leak water, it will not leak, very serious
- The direction of the arrow on the valve body refers to the direction of the medium.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.
- Q: Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why? How does the number of valves effects the performance? Many thanks.
- the v is in reference to the motor its in a v formation v8 4 cyliders on each side v6 3 per side v12 6 pre side now the valves is how many are in each cylinder you usually have 3 or 4 valves per cylinder the more valves the more horsepower the more cylinders the bigger the engine
- Q: Who was the first doctor to discover Pulmonary Valve Stenosis? Also, who was the first doctor to perform surgery for it? Please and thank you for your help.P.S. I have this condition.
- 1761 - Pulmonary valvar or valvular stenosis is one of the more common forms of congenital heart malformations and it has been extensively studied since the original description of pulmonary valve stenosis by John Baptist Morgagni in 1761. 1888 - Tetralogy of Fallot, first characterized by Dr.Etienne Fallot in 1888, is present in about 3000 children born each year in the United States. It is a combination of four heart abnormalities. Dodrill and his colleagues employed it with success for the open correction of a stenotic pulmonary valve in October 1952.
- Q: Butterfly D371X5-16ZB1 what does each letter stand for?
- Daily valve pressThe regular model is out of step with you. I can only explain the regularD371X5-16ZB1D is butterfly valve3 is the turbine drive7 is the clamp connection1 is the display opening signX is a rubber seal16 is 16 kg pressureI don't know the other superfluous letters
- Q: When i waa replacing the valves in the las 4 valves , they dropped and i dont know how to make them go back up, and i dont want to take the engine out of the car, is there any tool to make the valve go back up or there is any way to do it?? People told me that i can crank it by and , but i dont know how to do it where do i have to do it, i need help please im begging for help!
- As you've been asking this question for a week now time and time again I guess its time for the Nasty one to set you straight, As I've been a mechanic for over 30 years my knowledge is vast and no further questions need to be asked, You screwed up! now that you have dropped the valves into the cylinders you have to remove the head or heads that you screwed up on, period, end of sentence, there is no other way, and no you will not need to remove the engine to remove the heads, But had you did a bit of research before diving into this without a clue you would have found that a simple length of clothes line or thin rope stuffed down the spark plug hole and turned the engine over by hand to bring the piston up and push the rope into the valves to hold them place would have saved you from pulling the heads off this POS, excuse me I meant fine piece of English engineering, by trying to turn the engine over now is just a good way to bend a valve, and for all you know the piston could have been at the bottom of its stroke and the valves fell out of there guides are not even in contact with the head, so with this said do some research on how to remove the heads on this thing and fix your screw up. Live and learn, you just opted to learn the hard way,
