摘要： A double-walled contained shear valve comprises of an inner housing forming a fuel flow path, and a containment housing surrounding the inner housing, either partially or wholly, to provide a secondary containment. An interstitial space is formed between the inner housing and the containment housing as a result, and may be placed under a vacuum or pressure level to monitor for leaks. A vacuum actuator coupled to the interstitial space automatically opens and closes the fuel flow path of the shear valve in response to the vacuum level in the interstitial space to prevent leaks to the environment. The shear valve may contain a flange for connection to internal fuel dispenser piping that either does or does not includes interstitial space orifices to couple the shear valve interstitial space to the fuel dispenser piping interstitial space to monitor the vacuum or pressure level in these interstitial spaces as one contiguous space.

摘要： A double-walled shear valve that carries fuel from a branch or main fuel piping to fuel dispenser piping. The double-walled shear valve comprises a containment housing defining a shear groove on the outside circumference of the containment housing and an inner housing defining an inner housing orifice therein forming a fuel flow path. The inner housing is coupled to the containment housing, and at least partially surrounded by the containment housing, such that an interstitial space is formed separate from the fuel flow path between the containment housing and the inner housing. The double-walled shear valve further comprises a main poppet valve coupled to the inner housing that is adapted to close the fuel flow path to prevent flow of fuel.

摘要： A shear valve employing a two-stage main poppet valve. The two-stage main poppet valve that can be opened with less force than normally required by prior art designs. For example, if there is pump pressure trapped on the upstream side of the two-stage main poppet valve and little or no pressure or atmospheric pressure on the downstream side, more force than can be provided may be required to open the two-stage main poppet valve to reset the shear valve after the two-stage main poppet valve is closed. The two-stage main poppet valve is designed to first begin to equalize pressure differential across the shear valve without opening a main poppet valve head from its seat inside the shear valve. Thereafter, the main poppet valve head can be opened with less force than otherwise would be required.
