Spring.
By using above-mentioned technical proposal, self-lubricating bushing is formed by iron-based powder by powder metallurgy sintered, is sintered
In the process, self-lubricating bushing pore-size can be controlled, therefore can form microcellular structure and oil duct, be lubricated separate are as follows:
Self-lubricating bushing is handled using preceding immersion oil, so that lubricating oil is adsorbed in micropore, when the intracorporal piston of valve and self-lubricating serve as a contrast after installation
When set generates friction, due to frictional heat generation, self-lubricating bushing surface pore increases, and lubricating oil overflows, and plays self-lubricating function, cold
But lubricating oil can be sucked back into again after, to reduce the abrasion and heat inside graduated release valve, positioning ring and valve body are integrally formed knot
Structure, internal jump ring is for fixing self-lubricating bushing.
The utility model is further arranged to: second mounting hole includes two for installing the four-way of non-return valve seat
Hole and fifth hole for installing handle set, two fourth holes are interconnected with two fifth holes respectively, fourth hole
It is interior to be equipped with caulking groove, the self-lubricating abaculus of adaptation is equipped in caulking groove.
By using above-mentioned technical proposal, fourth hole is for being adapted to non-return valve seat, and fifth hole is for being adapted to handle, certainly
The material for lubricating abaculus is identical as the material of self-lubricating bushing, can also play the role of reducing abrasion and reduce heat.
The utility model is further arranged to: the self-lubricating bushing is equipped with angularly disposed v notch v.
By using above-mentioned technical proposal, v notch v is opened up so that self-lubricating bushing can when being installed in the second through-hole
Radial contraction is generated, is easily installed, while improving the stability after installation, due to the effect v notch v two of radial force after installation
Side wall shrinkable conflict closing again.
The utility model is further arranged to: the valve body surface be equipped with zinc coat, zinc coat with a thickness of 0.008-
0.025mm。
By using above-mentioned technical proposal, zinc coat can play etch-proof protective effect to valve body.
