KROM SCHRODER止回閥GRS 15R產(chǎn)品介紹
止回氣閥GRS可防止蠕動并逆著預期的流動方向進行喘振。帶有阻火器GRSF的止回閥還可以停止燃燒氣體-空氣混合物的回火，即使在回火后仍可防止氣體回流。
該設備用于保護操作燃氣設備或燃氣裝置的燃氣分接點，并且在這些燃氣分接點處，通過設計措施無法防止氣體倒流到空氣供應管線中或空氣倒流到氣體供應管線（易燃混合物）中。因此，它防止了供應管線中易燃混合物的形成。
GRS并非撲朔迷離，因此只能與附加的安全裝置結合使用，該安全裝置在回火時會切斷氣體供應。
在GRSF的情況下，它可以僅與燃燒空氣（非純氧氣）一起用作符合EN 730的阻火止回氣閥。
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).
