One end is placed on the conflict of the side on limiting section and with sealing, and the other side of sealing and valve seat contradict.
The present invention is further arranged to：The oil inlet end is equipped with the card slot being recessed by introversion and extroversion, and valve seat is sticked in card slot
It is interior, the positioning ring contradicted with sealing end surface is additionally provided on valve seat.
The present invention is further arranged to：The material of the spring base is ST16 deep drawn steel plate, and the material of valve body is 2A06
Aluminium alloy.
A kind of processing method of the excessively oily reinforced by-passing valve of engine cold-start, it is characterised in that：Include the following steps：
One, the processing of spring base：Spring base is to be added using the ST16 deep drawn steel plate of 0.8mm-1.2mm by punching stretch
Work molding, and carry out zinc-plated processing；
Two, the processing of spring：Spring is formed using carbon steel wire bending machining, and by being heat-treated to 32HRC-
36HRC, spring surface carry out blackening process；
Three, the processing of valve body：Valve body is to be formed using 2A06 high intensity aviation aluminium bar by lathe process；
Four, the processing of valve seat：Valve seat is to be formed using 45# medium carbon steel by turnery processing, and carry out electroplating processes；
Five, it assembles：Spring, valve body and valve seat are installed in spring base, using the assembling that presses between valve seat and spring base
Molding.
Six, it detects：The cracking pressure of by-passing valve is detected by pressure checking device.
It is had the following advantages that by using above-mentioned technical proposal：By setting limiting section on valve body, opened by excessive
After the pressure for opening direction, being contacted by limiting section with the bottom of spring base can be avoided spring doubling-up, and the decrement avoided is more than
Limited compression, to guarantee that the cracking pressure of valve body is not in violent relaxation phenomenon；The material of valve body is High-strength aluminum product,
Spring base is deep drawn steel plate, the hardness of the two there are biggish difference, be avoided that during frequent open valve body with
Abrasion between spring base, to solve the problems, such as that spring base is broken in use, service life is able to extend one
Times or more.
Detailed description of the invention

Specific embodiment
With specific embodiment, the invention will be further described with reference to the accompanying drawing, referring to Fig. 1-2：
A kind of excessively oily reinforced by-passing valve of engine cold-start, it is characterised in that：Including spring base 1, valve seat 2,3 and of spring
Valve body 4, spring base 1 include oil inlet end 5 and several oilholes 6 being placed on spring base side, and valve seat 2 is fixed in oil inlet end 5, bullet
Spring 3 and valve body 4 are also placed in spring base 1, and valve body 4 includes the sealing 7 and limiting section 8 being connected, and 3 one end of spring is placed on limit
It is contradicted in position portion 8 and with the side of sealing 7, the other side of sealing 7 and valve seat 2 contradict.
When input pressure reaches threshold values, 3 forced compression of spring, valve body 4 is inwardly moved, and sealing 7 and valve seat 2 divide point
From oil inlet end 5 is connected to oilhole 6 realizes that oil inlet, the setting of limiting section 8 are set in spring 3 on limiting section 8, first
It can be avoided spring 3 and be compressed to bottom, is i.e. generation 3 doubling-up phenomenon of spring, the decrement avoided oversteps the extreme limit compression, and damages spring
3, to also ensure that the cracking pressure of valve body 4 is not in violent relaxation phenomenon, second play radially limiting to spring 3
Effect, plays the role of further protection.
The oil inlet end 5 is equipped with the riveting slot that be recessed by introversion and extroversion, and valve seat 2 and riveting slot rivet, valve seat 2 include with it is close
