V-shaped ball pneumatic valve installation and debugging

v-shaped ball pneumatic valve installation and debugging
v-shaped ball pneumatic valve before installation need to do the following work:
( ） V-shaped ball pneumatic valve inspection: the inspection have to install a v-shaped ball; pneumatic valve is suitable for the operating conditions Check the installed V pneumatic valve ball sphere as well as the parts are in good condition; Check the need to install a v-shaped ball pneumatic valve ball attachment is complete; Long-term storage of v-shaped ball of pneumatic valve performance is qualified. Conditional v-shaped ball for all will be installed when the pneumatic valve performance testing, qualified after the installation.
　（ ） Check pipeline: pipeline for new construction, before the installation of v-shaped ball pneumatic valve need to clear in time the impurity in the pipeline, in order to avoid a v-shaped ball at the beginning of pneumatic valve in the damaged when the phone is switched on.
v-shaped ball pneumatic valve hoisting: to use the right tools and methods to lifting products, in order to avoid a v-shaped ball during installation of the pneumatic valve was damaged.
v-shaped ball pneumatic valve installation: please design firm support on the welded pipe, pipe weight is forbidden by the pneumatic valve body, it will use of v-shaped ball pneumatic valve performance influence. V-shaped ball pneumatic valve (for large caliber, The DN above) To the pneumatic valve body on both ends of the pipe support.
debugging v-shaped ball pneumatic valve: v-type ball pneumatic valve products are through strict test before they go out, if there is any attachment assembly, v-shaped ball after pneumatic valve assembly are carried on the preliminary debugging, for the sake of your system can run accurately, the v-shaped ball pneumatic valve installation is complete, v-shaped ball pneumatic valve must carry on the fine adjustment, so that the system normal operation; V-shaped ball pneumatic valve testing conducted by professional debugging personnel.
v-shaped ball pneumatic valve system commissioning: after the installation is complete, the system to conduct a trial run, to ensure that the v-shaped ball pneumatic valve fully adaptive control system.
v-shaped ball pneumatic valve repair: a v-shaped ball pneumatic valve in use process may appear problem, according to different problems, take a different approach. Common problems are as follows:
filler leaks, causes: ( ） May be due to packing bolts not compaction; （ ） Run for a long time, packing wear. The solution: ） Use special wrench to tighten the packing gland nut; （ ） Remove the packing gland, the change of packing. Usually tighten packing gland nut can solve the problem.
gland leakage reason: after damage of o-rings. Solution: replace the o-rings.
flange joint leakage causes: ( ） The flange gasket lose elasticity; Solution: replace the flange gasket. （ ） The flange gasket dislocation; The solution, laid gaskets flange sealing surface position again.
seal outer leakage causes: o-rings or graphite ring damage; Solution: replace o-rings or graphite ring.
seal seat leakage causes: (with pneumatic valve core ） Closing degree of actuators have not reached; Solution: adjust the actuator stroke, which can completely in the close state. （ ） Sealing surface wear; Solution: remove the seal, remove the ball and seal seat and pneumatic valve core are grinding repair. If seal seat was badly damaged, to replace the seal seat.
actuator air leakage causes: o-rings badly damaged; Solution: replace o-rings.
pneumatic valve core jam causes: ( ） Pneumatic valve core and impurities are stuck between pneumatic valve seat; Solution: let the actuator reverse action, remove the impurities and then check whether the pneumatic valve seat is damaged, if it is not damaged, continue to use, if pneumatic valve seat is damaged, replace the pneumatic valve seat back again after use. （ ） Medium produce crystallization, pneumatic seat cavity after spring chamber filled with medium, pneumatic seat can't float; Solution, change the pneumatic valve seat structure, make the medium is not easy to spring chamber. （ ） Pneumatic valve seat due to thermal peng up card dead, the main reason is that the product structure is not suitable for working condition requirement, solution: change the products structure, use suitable for the working condition of the product. （ ） Actuator configuration is too small. Solution: increase the actuator torque.
