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:Where is the PCV valve?
pcv valve is on the valve cover closest to the firewall.it is attached to a rubber hose that runs to the intake. right below an electrical plug
Q:Does the wet alarm valve group need to install the signal butterfly valve?
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 network and ordinary butterfly what is the difference?
Butterfly valve used in the network structure, closed with the more closed, the more tight function, reliable sealing performance, after opening and closing, make sure that the cover is completely out of touch, to ensure that the sealing surface is not damaged. The sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by the spatial units, can be installed in any direction.
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.
Q:What is the meaning of American Standard butterfly valve B series
American Standard flange connection is divided into A, B series. A series for normal flanges, B series for compact flanges. 24 "to no AB series, flange standards for B16.5, 24" above B16.47.
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:Seat Leon Cupra 1.8T Mk1. Is my seat fitted with a dump valve as standard.?
every turbo will have a dump valve(waste gate) to regulate the boost to the engine Dump valves are fitted to the engines of turbo charged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pressurize air, but the closed throttle prevents the compressed air from entering the engine. In this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere. Even with a dump valve the compressed air acts as a brake on the turbo (slowing it down), because the pressure on the backside of the turbo is at a higher pressure than on the front side (and the air actually wants to flow through the turbo backwards). A blowoff valve is a more elegant solution to this problem by allowing the turbo to freewheel when the throttle is closed (equalizing the pressure on both sides of the turbo). Unlike a dump valve a blowoff valve can be used at multiple boost settings without reconfiguration. Blowoff valves are sometimes incorrectly called dump valves because they serve a similar function, but they are very different solutions to the same problem.
Q:What's the difference between D71X-16 and D71H-16 butterfly valves?
Model D71X model means this, D represents butterfly valve, 7 represents butterfly connection form for clip type connection, 1 represents straight through, and 16 represents pressure 16 kg pressure.X stands for sealing and soft sealing, and the sealing surface is usually nbr.H stands for metal hard sealing, usually 2Cr13 surfacing.D71X-16 butterfly valve featuresIts main features are:1 、 the design is novel, reasonable, unique structure, light weight, fast opening and closing.2 、 small operating torque, easy operation, labor-saving and smart.3. It can be installed and maintained conveniently in any position.4, seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.5, sealing materials aging resistance, corrosion resistance, long service life and so on.
Q:What is the difference between wafer (flangeless) type and LUG type of butterfly valves?
WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
