ZZHP 指揉操作自力式庄力凋苧 (蜀封閥) ZZHP Self-Acting Pressure Regulating Valve Nitrogen Sealed Valve!

ZZHP 型指拝器操作自力式圧力凋帝閥（気封閥）　是一稗无外来能源, 利用被凋介贋自身的圧力交化送到自功凋苧和稔定閥后圧力投定値的帝能型庄力凋苫閥。

The ZZHP self-acting pressure regulating Valve Anitrogen sealed Valve) is än energy-saving pressure regulating Valve that operates without the need for external power sources. It utilizes the natural pressure changes of the controlled medium to automatically adjust and Stabilize the pressure downstream of the Valve t0 A predetermined value.

The pressure setting of this Valve is accomplished through the controller, Which is Convenient and swift. The set pressure Value can also be adjusted freely during operation. Its high contro! precision makes it Suitable for situations Where the upstream pressure { ~ \bf ~ P ~ } <=slant { ~ 1 ~ } MPa and the downstream pressure { \Delta P _ { α } < \Delta 1 0 \ k P a } It is designed for on-off contro! Father than continuous contro! but excels in applications Where high precision is required. This Valve finds extensive use in industries such as chemical, petroleum, metallurgy, power generation, textiles, etc., serving as an automatic regulation device in production processes, particularly Well-suited for nirogen-sealing systems in Storage tanks. The pressure reduction ratio of this valve is 1:l00.

系列分閥前式 ZZHP-16K 和后式 ZZHP-16B, 岡前式只用在柚気装賈上 并旦与供気装畳配養使用 In this Series, there are back pressure type ZZHP-16K and pressure reducing type ZZHP-16B. The back pressure type is exclusively used in nitrogen Venting systems with the support of nitrogen Supply equipment.

Operating principle? The medium enters the Valve body in the direction indicated by the arrow. One Stream of the medium, along With the pressure reduced by the fiter pressure reducer, is introduced into the controller. Another tream of the medium passes through the Valve core and valve seat, and after throttling, the pressure flows towards the Valve post. This pressure is then introduced into the actuator of the controller through the pressure guiding tube. When the pressure behind the Valve exceeds the set pressure, it exerts 1 force On the effective surface of the diaphragm of controller. driving the Valve core of controller t0 close. This action cuts off the pressure in the membrane chamber of the main Valve actuator, causing the main Valve core t0 close, Subsequently reducing the pressure behind the Valve. When the downstream pressure falls below the set value, the counterforce of the main spring in the controller opens the Valve core of controller. The upstream pressure is then introduced into the membrane chamber of the main Valve actuator, generating thrust and causing the main Valve core to Open, subsequently raising the downstream pressure. This cycle continues to maintain the pressure behind the valve at the set value.
