Valves must be stored in a dry and ven tilative room.b. During the period of storage, The disc should be always be shut and fixed a
12、nd the inlet and outlet should be blocked.c. During the period of storage, the outside portion of the stem and the machined surface should be covered by an easily clea ned an tirust.d The valve stored for a long time should be inspected and cleaned at an expected time. At the same time, the an tirus
13、t should be re-brushed.5. 2 Installationa. The valve can be in stalled freely, Usual used in horiz on tal pipe line ,and can also used invertical or bevel pipe line, but it should be convenient to maintenan ce, in specti on and operati on.b. Before installation, operators must review whether the con
14、tents on the marking and n ameplate conform with the practical requireme nts.c. Before in stallati on, operators must in spect the in side , remove the disc fix set ,a nd try to turn on the disc to check the seal face ,and clear it.d. Installation this valve , must be note the flow way of the medium
15、 , and must keep same way of the medium and the arrowhead ,otherwise can stop the n atural way of medium.5. 3 Usinga. The practical condition intending to use valves must conform with the requirements specified on n ameplate and in the operatio n in structi on.b. The valve only works for getting or shutting off medium. Mustn ttake it as the regulati on valve.c. When shutting the valve ,it will have water hammer in the pipe line , badly will damaged the valve , so the user should inspect on time , if find some problem repair in time .5.
