Quick Couplings And Knowledge of Pneumatic Fittings
Quick couplings, a tool can be achieved without piping connected or disconnected joints. Quick couplings can be divided into: air with quick couplings, quick couplings with oxy-fuel gas, gas liquids share quick coupling, hydraulic quick couplings, quick couplings with an inert gas, cooling water temperature of the oil with quick couplings, semiconductors, connectors.
Why use it fast connection? Save time and effort: The quick couplings split off and connected manifold, the action is simple, saving time and manpower. MPG: broken oil line, the quick couplings on the individual valve can be closed circuit, the oil will not flow, to avoid loss of hydraulic oil. Environmental protection: quick couplings broken and connected, the oil will not spill leakage, protecting the environment. Equipment decentralized, convenient transport: need for large equipment or portable hydraulic tools, quick couplings, after splitting the transport, the destination and then assembled to use. Economy: All of the above advantages are creating economic value for our customers.
Rapid decomposition of joint instructions. Including a female connector mother, the mother on the set of a hole, through hole embedded in a steel ball; a male connector cylinder, cylinder surface has a groove; a sleeve; described the mother and the male connector female connector with cylinder seal, mother on the ball snaps into the groove within the cylinder surface; above card condom female connector located at the outer surface of the mother, characterized in that: also includes a pull set, pulling a condom in the male connector located on the cylinder surface, and its internal thread and the female connector on the card sleeve connection.
Mold quick couplings is mainly used for general-purpose mold interface connectors. Also known as cooling water, temperature and oil with quick couplings.
Mold structure divided by quick couplings, can be divided into; both ends of the open closed, open at both ends, single retractable.
Both ends of the retractable: no link in the ring when the mother moved to the other side, the stainless steel beads rolling out automatically, daughter mother and daughter because of the valve spring force of the force co-operated and disconnected, daughter and their mother's valve closed, blocking fluid flow instantly. Link into the mother when the daughter, the rings under the action of the spring back to its original position, locking ball rolling in close connection child while the mother and daughter co-promotion and open the valve, fluid flow, O-ring completely blocked the fluid leakage.
Open at both ends: not link when the mother's ring was pushed to the other end, the ball roll out automatically, so daughter was out; as daughter and mother are no valves, fluid flowing. Link when the daughter into the mother, the ring was his role in pushing the spring to the previous position caused steel ball locking, fluid flow, in which the O-ring to prevent fluid leakage.
Single retractable: no link of the ring when the mother moved to the other side, the stainless steel beads rolling out automatically, daughter of the reaction by the valve spring bounce, the valve will automatically shut down to block the fluid flow . Link into a ring when the daughter's maternal side, the valve is opened leading to fluid flow, the strength of the spring washer is pushed back into place, stainless steel bead will lock to ensure that the child / parent connection, which the gasket can completely blocked the leakage of fluid.
The role of pneumatic fittings using impact or rotational effect of air pressure to exercise or to make successful. Pneumatic fittings pressure or by gas expansion forces generated by the components to do work, about the elastic energy of compressed air is converted to kinetic energy of the parts. Such as cylinder, motor, steam engine and so on. It is a form of power transmission, also the energy conversion device, using air pressure to transfer energy.
Compressed air for pneumatic fittings power source is to drive the completion of stretching or rotating mechanical action. Because the air is compressed using the characteristics of inhaled compressed air storage, air will be the same as with the elastic spring, and then control element to control its direction of rotation and drive the implementation of flexible components. The number of air inhaled from the atmosphere, how much will discharge into the atmosphere, will not produce any chemical reaction, air pollution is also not consume any component, other than the gas in the viscous fluid is smaller, so flow speed, so that the main features of is the energy-saving environmental protection.
Pneumatic valve pneumatic fittings valve is a pneumatic fittings device in. With compressed air-driven valves. Only clear when the pneumatic fittings valve procurement specifications, type, working pressure to meet the procurement requirements of the practice, in the current environment of market economy is incomplete because the pneumatic fittings fittings valve manufacturer for the product competition, each design are unified in the pneumatic fittings valve under the concept of for different innovations, formed their own company standards and product personality. Therefore, pneumatic fittings valve procurement made a more detailed technical requirements, coordinating with manufacturers to reach a consensus, as the pneumatic fittings valve procurement annex to the contract is necessary.
Pneumatic actuator is a kind of pneumatic fittings , and its implementing agencies and regulatory bodies are unified as a whole, its implementing agencies have membrane, piston, fork-style and rack and pinion. Piston stroke length, for applications that require a greater thrust of the occasion; and film-style travel less, can directly drive the valve stem. Fork-type pneumatic actuators with torque, small space, more torque curve characteristics of the valve of the torque curve, but not very beautiful; commonly used in high torque of the valve. Rack and pinion pneumatic fittings actuators are simple, smooth and reliable action and safety explosion-proof advantages, such as power plants, chemical, oil refining and other safety requirements on higher production in the course of a wide range of applications.
