Q:How big is the butterfly valve with a diameter of 80?
With the 80 caliber butterfly valve.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.
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:Butterfly valve common faults and treatment methods?
Three, summary:Only familiar with every detail of circulating water pump outlet valve and butterfly valve equipment, timely and thorough maintenance and strict debugging, to ensure the safety and reliability of equipment operation, to ensure the healthy and orderly operation of equipment.
Q:What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
Liu1964tg, this guy is right, don't know, don't mislead everybody
Q:What is the difference between the installation and function of a butterfly valve and butterfly valve?
Therefore, the fully open position of the valve is determined by the position of the gate. Some gate valve, stem nut is located on the gate, the handwheel rotates to drive the stem to rotate, and make the gate lift, this kind of valve is called rotary bar gate valve, or call dark rod gate valve. The type of gate width, sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate type valve can be divided into single and dual gate gate plate. According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve. Valve installation and maintenance should pay attention to the following: hand wheel, handle and transmission mechanism are not allowed for lifting, and is strictly prohibited. Double gate valve should be installed vertically, that is, the valve stem is in a vertical position, and the handwheel is at the top. The gate valve with bypass valve shall be opened before opening to balance the pressure difference between inlet and outlet and reduce the opening force. The gate valve with drive mechanism is installed according to the instruction of the product instruction. If the valve is constantly switched on, lubricate it at least once a month. The valve has the advantages of small fluid resistance, the sealing surface by the erosion of small and medium Chong brush. Opening and closing is more labor-saving. Medium flow direction is unrestricted, no disturbance, no pressure reduction. The utility model has the advantages of simple shape, short structural length, good manufacturing technique and wide application range. Valve faults between the sealing surface can lead to erosion and abrasion, maintenance more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
Q:What is an ERG valve?
The EGR valve is there to reduce nitrous oxide emissions and lower the temp of the combustion charge. This has the affect of reducing the octane requirement of the engine. This isn't a bad thing. When the valve hangs open, the thing will run bad at idle and could even die. The thing is, the valve could be perfectly fine and the sensor could be bad. Since some states won't give you a sticker if the light is on, you're probably stuck with replacement.
Q:toyota mechanic valve adj 1.8l?
valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.
Q:2003 Caravan valve gasket?
the valve pan gasket won,t cause it but the fuel filter will if it,s starting to clog up and also the cat.converter !
Q:I want to what is better a metal valve or tissue valve replacement for someone who is in their 30's?
Do you want to have kids or have more kids? This is going to be the biggest question you have to answer. The tissue valve will require no treatment after the replacement, other than another replacement in 10-15 years or whenever the valve starts to fail. The mechanical valve will most likely last the rest of your life, but will require the use of anticoagulants that would make any future pregnancy extremely risky. As to the sound many patients complain about hearing the valve clicking in times when it is very silent (dead of night etc.) Most find that keeping a Radio or tv on at a low level solves the problem, Id say in my experience about 50% of patients complain about hearing the clicking. The other issue is that using tissue valves, it is a slightly riskier operation every time you re-open someones chest, due to scar tissue formation. So instead of say 1-3% risk it might be 5% if the person is young and healthy. This is important since the tissue valve will only last 10 maybe 15 years. The atrial thrombus complicates matters, however which valve are they replacing? It might be possible to remove the thrombus at the same time as doing the valve. If not, mo matter what you will be taking warfarin, so the vavle choice really will not matter that much.
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)
