The tap function and identification method of pneumatic valve core

pneumatic valve core is used in the faucet, pneumatic valves and other fluid system in one of the important parts of control components. Small make up today is to introduce the water tap and identification method of pneumatic valve core.
the faucet pneumatic valve core role
pneumatic valve core is using it to implement the direction control, pressure control or flow control the basic function of the pneumatic valve parts. Any a faucet switch control requires a pneumatic valve core, for the faucet, the quality of the pneumatic valve core is the important basis of the faucet quality assessment, can say the key to affect the quality of the faucet is pneumatic valve core. Common faucet pneumatic valve core are steel ball pneumatic valve core and ceramic pneumatic valve core. Steel ball pneumatic valve core has a good ability to resist pressure, but the disadvantage is that plays a role of sealing rubber sealing ring is easy to loss, will soon be aging. Compared with steel ball pneumatic valve core, more heat-resistant wear-resistant ceramic pneumatic valve core, pneumatic valve core and ceramic itself has good sealing performance, therefore can achieve very high resistance to open a number, not caused by pneumatic valve core wear mouth dripping water. Adopt ceramic pneumatic valve core bibcock, feel more comfortable and smooth, also on the open, close and quickly.
there are three kinds of common pneumatic valve core: stainless steel ball, pneumatic valve, pneumatic valve core and ceramic chip roll shaft type pneumatic valve core. The common characteristics of these three kinds of pneumatic valve core is wholeness, the spindle, easy installation and maintenance, replacement.

faucet pneumatic valve core identification method: the handle of the tap, to feel with the hand, context switches midway have blocked when feeling! ( Blocked it means bad
: switch to a half, the pneumatic valve core to stop. Then whisk in place! To compare with feeling, upper and lower handle is the same! ( Slightly upscale pneumatic valve core can achieve this
: pneumatic valve core ( Adjust the hot and cold! ( With above method first and then see the weight, good about pneumatic valve core is 'idle', also is the feel is very light!
: use forefinger, middle finger nipped gently tap handle gently moved up and down or so, the concept of the flexible is not loose, blocking feel, whether there is oil damping handle, such as flexible not loose, without blocking the feel and feel of heavy oil damping can buy!
