GB/T 5634-2008Flared couplings - Swivel run tee (English PDF)

Foreword

This standard is one flared fittings series. This standard is GB/T 5634.1-1985 "flared combination right angle tee" and GB/T 5634.2-1985 "flared group Amendment co-rectangular tee Style ". The main amendments are.

--- The two standard content integration;

--- Modified Chinese and English name;

--- Increasing the hexagonal structure of the blank;

--- Reducing the parameters should be part of the manufacturer's control;

--- Tolerance on the part of prevailing standards of tolerance and fit adjustment;

--- Cancel the marked surface roughness, surface roughness is given in GB/T 5653 "flared fittings technical conditions" in. Since the implementation of this standard replaces GB/T 5634.1-1985, GB/T 5634.2-1985. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee pipe accessories.

1 Scope

China's national standard for the flared tube swivel run tee. In a run tee the through path passes across the port and the port forms the third leg, so the fitting is used to pick up a supply from a component while the main line continues past it - the arrangement used when several actuators are fed in series along one line. The swivel construction lets the run rotate relative to the threaded body, which is what allows the through tube to be brought in on its natural line rather than on whatever line the thread happens to leave it. On a machine where a single pressure line serves a series of valves, the difference between a run tee that can be clocked and one that cannot is whether the line can be made from straight tube at all. The standard specifies the dimensions, marking and technical requirements of the swivel run tee and its body, for tube outside diameters of 4 to 34 mm at 3.5 to 16 MPa.

This standard specifies the dimensions, marking and technical requirements flared combination elbow tee and the joint body. This standard applies to pipe outside diameter 4mm ~ 34mm, the maximum working pressure of the hydraulic fluid and transmission of a 3.5MPa ~ 16MPa General purpose piping system.
