According to informed Lixin fittings, pipe joints card sets are hard seal pipe joints which connect a meter, using the card in the middle ring seal (common ring clasp with a single card and dual card ring), is to rely on lock fittings the role of the nut and fitting body oppression collar embedded steel wall, thereby forming a seal. Wenzhou valve production plant towers card sets are divided into the connector body joints, ferrules, nuts three parts. When the card holder and card holder sleeve locking nut on the pipe inserted into the connector body, when you tighten the nut, the outside of the front ferrule and fitting body taper fit evenly in the biting edge of seamless steel tubes to form an effective seal. Ferrule fittings General pipes have steel, copper, iron and other precision seamless tubes.
Ferrule tube fitting installation:
A selection of the instrument to adapt to the seamless steel pipe length. Perpendicular to the axis of the pipe end, angle tolerance not more than 0.5 degrees. If you need to bend steel, the pipe end to the curved portion of the line segment length can not be less than three times the length of the nut.
2 of the lock nut and ferrules fixed on the seamless steel tubes. The direction of the nut, ferrule first time after installation.
3 In the pre-assembled connector body Lubricate the threads and put the card, insert the pipe connector body (pipe must be inserted in the end) Tighten the nuts by hand.
4 Tighten the nut until the ferrule stuck pipe, the turning point in the tightening torque can be increased by feel (pressure points).
5 After reaching the pressure points, and then tighten the nut 1/2 turn.
6 pre-assembled connector body removed, embedded in the inspection side of the sleeve edges, protrusions visible space must be filled with the front of the card sets. Card sets can be slightly rotated, but not axial movement.
7 final installation, thread coated with oil will actually install the connector body, tighten the compression nut to increase co-ordinated with the tightening force can be felt far and then tighten 1/2 turn installed.
All fittings can be reloaded several times, but to ensure that no damage and clean the parts.
1. The pipe into the connector body until snapping connector ferrule body cone, hand-tighten the nut.
2 Use a wrench to tighten the nut until the tightening torque increases rapidly, then tighten 1/4 to 1/2 turn to.
Pipe assembly can be removed to check whether it is required: the ends of the pipe sleeve should have a uniform slight bulge. Card sets can slide back and forth, but allow a slight rotation.
Leakage ferrule fittings are: installing pipe cutting uneven, do not plug into the bottom of the pipe joint, lock nuts are not tightened, the outer surface of the pipe roughness, pipe sizes, pipe too hard.
