Stainless Steel Spring Check Valves - Engine Valve Manufacturers.
Stainless Steel Spring Check Valves
- steel containing chromium that makes it resistant to corrosion
- A form of steel containing chromium, resistant to tarnishing and rust
- In metallurgy stainless steel, also known as inox steel or inox from French "inoxydable", is defined as a steel alloy with a minimum of 10.5 or 11% chromium content by mass. Stainless steel does not stain, corrode, or rust as easily as ordinary steel, but it is not stain-proof.
- (Stainless steels) Steels that are corrosion and heat resistant and contain a minimum of 10% to 12% chromium. Other alloying elements are often present.
- (Check valve) A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction.
- A valve that closes to prevent backward flow of liquid
- (Check valve) used to provide flow through a pipe in one direction only. When installed between an external filter and the pond, it keeps the dirty water in the filter from flowing back into the pond if power is lost. They are also used to keep an external pump primed if power is lost.
- (Check valve) A device inserted into a moving liquid stream that allows flow of the stream in only one direction; most often used on the inlet and outlet sides of an HPLC pump.
- Operate or cause to operate by means of a mechanism
- Move rapidly or suddenly from a constrained position by or as if by the action of a spring
- a metal elastic device that returns to its shape or position when pushed or pulled or pressed; "the spring was broken"
- Move or jump suddenly or rapidly upward or forward
- the season of growth; "the emerging buds were a sure sign of spring"; "he will hold office until the spring of next year"
- jump: move forward by leaps and bounds; "The horse bounded across the meadow"; "The child leapt across the puddle"; "Can you jump over the fence?"
DSCF0304
Here is the finished bolt reinstalled in the manifold. It's loose enough to turn easily by hand at this point.
Another solution from the VCCA site:
A mate of mine had a 1938 Business Coupe that came from New Zealand,and it had a pronounced exhaust leak from between the heat control valve shaft and the exhaust manifold.
After taking off the manifold,we found the valve plate itself
was in real good order,we just had to figure out how to eliminate
the leak.
After marking the position of the plate in relation to the pin that retains the bi-metallic spring,I drilled out the spot welds holding the plate to the shaft.The shaft & the manifold were both badly worn,so I set the manifold up on the milling machine table,and put a cutter through that was 7/16" in diameter.
I then made 2 cast iron bushes as it would expand and contract at the same rate as the manifold.A new shaft was made out of high tensile high temperature stainless steel.The shaft &
valve plate were then "timed" to the pin for the bi-metallic spring,and a couple of spots with the mig had the valve plate fixed to the shaft securely.
I then hooked up the bi-metallic spring and checked to make sure it hold the plate in the "on" position when the engine was cold,and used a hot air gun to heat the spring up,and watched to make sure it gradually opened up as it heated up,which it did.
Then I liberally applied a chain & wire rope spray lube that contained a lot of graphite & moly-disulphide anti seize compounds,and problem solved.
No more exhaust leak,and a working heat control valve.
Water pump assembly
The machining of the pump is complete. The fine spring for the check valve was shop made from .009" stainless steel wire.
