摘要： A pressure protection device includes a housing, a sliding block, and an adjusting block. The housing includes a receiving chamber communicating with a seal chamber and the housing defines a first gas hole and a second gas hole each communicating the receiving chamber to an ambient environment. The sliding block divides the receiving chamber into a first space and a second space and defines a through hole communicating the first space with the second space. The adjusting block is located in the first space and configured to be attracted to the sliding block so that the through hole is selectively blocked by the adjusting block. When the sliding block slides in the receiving chamber, the first gas hole is selectively blocked by the sliding block to isolate from or to communicate with the first space, and the second gas hole always communicates with the second space.

摘要： Embodiments of the present disclosure are directed toward a pressure vacuum relief valve and a seal assembly of the pressure vacuum relief valve. The seal assembly includes a ribbed substrate disposed against a flanged seat of the pressure vacuum relief valve. The ribbed substrate includes ribs extending from a base of the ribbed substrate. The seal assembly also includes a pallet coupled to and disposed below the ribbed substrate. The pallet includes a top ring, a bottom ring, and a flexible diaphragm captured between the top ring and the bottom ring. The flexible diaphragm of the pallet is configured to seal against the ribbed substrate in a sealed position. The pallet and ribbed substrate are configured to move together away from the flanged seat when a pressure on a sealed side of the pressure vacuum relief valve exceeds a maximum pressure threshold. The pallet is also configured to pivot open at an angle relative to the sealed position of the pallet when the pressure on the sealed side of the pressure vacuum relief valve falls below a minimum pressure threshold.

摘要： The present invention generally relates to a Dual Action, Low Head Isolation Valve is a plumbing fitting that will isolate the interior pipes of a house from the exterior temperatures of summer and winter while allowing the passage of gasses through the system for venting. This valve would be installed at the top of the household plumbing drainage system, or the top vent, in the attic or above the roof. This valve will allow for the system to draw in air and exhaust the septic gasses, or respirate in both directions with very low head or resistance.

摘要： An evaporative emission control and leak detection system for a motor vehicle is provided. The system is in fluid communication with a fuel tank, an engine, and a carbon canister and includes an integrated valve module that is in fluid communication with the carbon canister and the atmosphere. The module provides for venting of the system when the system is exposed to predetermined high negative and positive pressure conditions, and a predetermined low negative pressure condition. The module also includes a switch that is operable to indicate when the system is in a high or low negative pressure condition for leak detection verification of the system.
