Portion 4 is integrally formed, so as to guarantee structural strength and leakproofness.
Referring to Fig.1, neck connects and runs through among mounting portion 2, bent portion 1, fixed eckband 12, sebific duct insertion section 3 and introduction part 4
Through flow hole 11 is offered, through flow hole 11 is used for flow of media；The wall thickness of bent portion 1 is greater than sebific duct insertion section 3 in the present embodiment
Wall thickness, so as to guarantee the structural strength and service life of dogleg section；Meanwhile bent portion 1 is heat treatment in the present embodiment
Bending, i.e. cold bending process are carried out after state, on the one hand can be improved production safety, after the bending that on the other hand can be improved product
Deflection, so that the flow of product hydraulic oil when in use is more stable.
Referring to Fig.1, neck connects mounting portion 2 and is integrally formed with bent portion 1 in the present embodiment, rather than welding fabrication, so as to
Enough improve structural strength and reliability；Neck connects mounting portion 2 and offers closure gasket groove 21, closure gasket groove far from the end face of bent portion 1
For being embedded sealing ring (attached to be not shown in the figure) in 21, so as to improve the leakproofness of installation place；Meanwhile liquid in the present embodiment
It bends pipe fitting to be made of unleaded steel, so as to increase environmental protection and intensity index, and neck connects mounting portion 2 and is able to bear up to
6000 pounds/square inch of operating pressure is further reduced the risk of junction oil leak.
Referring to Fig.1, the tapered face of the lateral wall of introduction part 4 in the present embodiment, i.e., the outer diameter of introduction part 4 is along sebific duct insertion section
3 taper off trend to the axis direction of introduction part 4, and introduction part 4 is inserted into sebific duct so as to facilitate；4 lateral wall of introduction part
Rounded setting at seamed edge far from sebific duct insertion section 3, so as to further facilitate in insertion sebific duct.
Referring to Fig. 2,3 lateral wall of sebific duct insertion section is provided with limit eckband 31 at fixed eckband 12, limits eckband 31
Fixed card slot is formed between fixed eckband 12, fixed card slot is used to limit the sleeve with the cooperation of hydraulic union elbow (in attached drawing
It is not shown) position；The cross sectional shape that eckband 31 is limited in the present embodiment is right-angled trapezium, and the bevel edge of right-angled trapezium is led with fixed
Circle 12 is opposite, and sleeve is embedded in fixed card slot so as to facilitate.
Referring to Fig. 2, the lateral wall of sebific duct insertion section 3 is opened up respectively there are two the first annular groove 32 and three the second annular grooves 33,
Wherein first annular groove 32 is located proximate to limit eckband 31, and the second annular groove 33 is located proximate to introduction part 4 (referring to Fig.1)；Glue
