Q:Which is more expensive, gate valve or butterfly valve?
Gate valves of the same material and specifications are much more expensive. The weight of the gate valve is much heavier than that of the butterfly valve.
Q:CAD drawing of butterfly valve
Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.
Q:Is the pressure test of the centerline butterfly valve checked or checked?
The pressure test of the central butterfly valve is carried out at each station.Basis:1) GB/T12238-2008 flange and clamp connection elastic seal butterfly valveRules: butterfly valve must be carried out by factory inspection and testing, inspection qualified before leaving the factory.2) CJ/T 261-2007, butterfly valves for water supply and drainageRules: each product shall be inspected by factory and quality inspection department. After inspection, the product certificate shall be attached to the factory.Butterfly: 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 air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. 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:Check valve; flexible joint `; installation order of electric butterfly valve
Connect the Songjiang rubber joint from the pump outlet. Check the 1 valve
Q:Read your answer, about pneumatic butterfly valve solenoid valve selection
DN200 pick 1/4DN350, DN400 corresponding solenoid valve, you can choose 3/8 hose 12mmOther accessories are related to valve path and pressure. If the same series, the valve has no change at all.
Q:What is the difference between the installation and function of a butterfly valve and butterfly valve?
The principle of the valve gate valve is open and close cases, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface forming wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate. Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing. Gate valve with the stem along with a straight line of motion, called the lift rod gate valve is also known as the bar gate valve. Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust. When opening the valve, when the gate lift height is equal to 1:1 times of the valve path, the passage of the fluid is completely unblocked, but at run time, this position is unable to monitor. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position.Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
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 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
Q:How do the butterfly valves d341 and d343 differ in appearance?
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. According to type code, transmission mode, connection form, structure form, sealing surface material or lining material, nominal pressure, material of valve body, regulate butterfly valve type.
Q:Should I connect the butterfly valve before and after the pump? Or gate valve?
The best pump outlet valve, because the valve opening control accuracy, no movement. Valve structure is strong, adjusting performance better than butterfly valve. The pump outlet needs constant switching and adjustment, so the pump outlet valve is suitable for gate valve.Life water system valve, it is best to choose the gate valve, strong and reliable, cut off the system to grasp. But the cost is higher, occupying more space.Choose 1 or 1.6, there is no principle requirements, because the water supply pressure of life is generally between 0.25-0.5MPA, can meet the requirements. Only 1.6 is more durable and stronger, but the price is higher.
