KROM SCHRODER止回阀GRS 15R产品介绍
止回气阀GRS可防止蠕动并逆着预期的流动方向进行喘振。带有阻火器GRSF的止回阀还可以停止燃烧气体-空气混合物的回火，即使在回火后仍可防止气体回流。
该设备用于保护操作燃气设备或燃气装置的燃气分接点，并且在这些燃气分接点处，通过设计措施无法防止气体倒流到空气供应管线中或空气倒流到气体供应管线（易燃混合物）中。因此，它防止了供应管线中易燃混合物的形成。
GRS并非扑朔迷离，因此只能与附加的安全装置结合使用，该安全装置在回火时会切断气体供应。
在GRSF的情况下，它可以仅与燃烧空气（非纯氧气）一起用作符合EN 730的阻火止回气阀。
The non-return gas valve GRS prevents creeping and surges against the intended direction of flow. The nonreturn valve with flame arrester GRSF also stops flashbacks of combustion gas-air mixtures and still prevents gas returning even after flashbacks.
The device is used to protect gas tapping points at which gas appliances or gas-fired installations are operated and where reverse flow of gas into the air supply line or of air into the gas supply line (inflammable mixture) cannot be prevented through design measures. It thus prevents the formation of inflammable mixtures in the supply line.
GRS are not flame-arresting and therefore may only be used in conjunction with an additional safety device which shuts off the gas supply in the event of a flashback.
In the case of GRSF, it may be used as a flame-arresting non-return gas valve in accordance with EN 730 exclusively with combustion air (not pure oxygen).
