Copper American Standard valve installation must be strictly in accordance with the established steps, the correct installation method is conducive to improving the service life of American Standard valve and performance, while installing the American standard valve to pay attention to some related details, to avoid unnecessary Of the operation errors, as follows: A, the American standard valve in the installation and commissioning process found stem leakage, tighten the packing at the compression nut, and pay attention to the force can not be too large, not water leakage; B, the connection valve Of the flange and the pipe end of the flange not only with the size specifications, and the nominal pressure required; C, pipe thread connection valve, the installation should be tightened when the wrench screw the same side of the hexagonal or octagonal parts, should not wrench the valve One end of the hexagonal or octagonal parts, so as to avoid valve deformation; D, the internal thread valve connected with the pipe end, the need to control the length of the pipe end of the external thread size. So as not to over-screwed into the end of the pipe so that the top of the valve pressure pipe end face, resulting in valve seat deformation and affect the sealing; E, pipe threaded valve and the pipe end pipe thread connection, which may be cylindrical thread thread may also be Conical pipe thread, while the male thread must be a conical pipe thread. Warm reminder: Before the installation of the American standard valve should be detailed inspection of its various components, the installation should be completed after its commissioning, testing whether the normal operation.
