Abstract
The present disclosure is directed to systems and methods which provide a seal-less high temperature and pressure valve for use in many applications.
Claims19
A high pressure, high temperature, seal-less valve, comprising:
- a body capable of generally housing a piston, wherein said piston is capable of being moved to actuated and unactuated position,
- wherein said valve does not include a seal, and
- wherein said valve is capable of operating with fluid at about 700 bar, 150 degree Celsius, for a cycle of 1 seconds, for one million cycles without failing.
The valve of claim 9, wherein said biasing member generally comprises stainless steel.
A hose test system, comprising:
- a control system operatively coupled to a test system, said test system comprising:
- a hose test assembly configured to connect to a hose to be tested, and between inlet high pressure valve and an outlet high pressure valve;
- an intensifier coupled to said inlet high pressure valve, capable of increasing the pressure within said hose test assembly when said inlet high pressure valve and said outlet high pressure valve are unactuated;
- wherein said control system is capable of controlling the operation of said intensifier of said test system.
1 more element
The hose test system of 13, wherein said test system further comprises an oil temperature control system capable of generally regulating the temperature of oil used within said test system.
A method of testing industrial and automotive hoses, comprising:
- cycling the pressure of relatively high pressure and temperature oil within one or more hoses in a test system, at least in part by actuating a pressure intensifier;
- isolating said one or more hoses at least in part using one or more high pressure and temperature seal-less valves, said one or more valves comprising a body capable of generally housing a piston, wherein said piston is capable of being moved to actuated and unactuated position, and wherein said valve is capable of operating with fluid at about 700 bar, 150 degree Celsius, for a cycle of 1 seconds, for one million cycles without failing.
