力士樂壓力閥DB52
力士樂壓力閥DB52壓力調節閥亦稱自力式平衡閥、流量控制閥、流量控制器、動態平衡閥、流量平衡閥，是一種直觀簡便的流量調節控制裝置，管網中應用流量調節閥可直接根據設計來設定流量，閥門可在水作用下，自動消除管線的剩余壓頭及壓力波動所引起的流量偏差，無論系統壓力怎樣變化均保持設定流量不變，該閥這些功能使管網流量調節一次完成，把調網工作變為簡單的流量分配，有效的解決管網的水力失調。

Pressure valve type DB is a pilot-operated pressure relief valve. It is used for limiting (DB) a system pressure.
The pressure relief valves basically consist of the pilot control valve (1) with pressure adjustment element (2), main valve (3) with main spool insert (4) and directional valve (5), optional.
Pressure relief valves type DB
The pressure applied by the system acts on the main spool (4). At the same time, pressure is applied to the spring-loaded side of the main spool (4) and to the pilot control valve (1) via the control lines (6) which are equipped with nozzles. If the system pressure exceeds the value set at the spring (7), the poppet (10) of the pilot control valve opens. The hydraulic fluid on the spring-loaded side of main spool (4) now flows via the spring chamber of the pilot control valve (1) to the tank, either internally via port T, or externally, via port Y. Due to the nozzle combination in the control lines, a pressure drop results at the main spool, the connection from P to T is thus released. The hydraulic fluid flows from channel P to channel T maintaining the set operating pressure.
The pressure relief valve can be unloaded by means of remote control or switched to another pressure value via port X (8).
Influencing of the switch-off time
The nozzle (9), by default equipped with Ø0.8 mm, is used to influence the switch-off time. By exchanging this nozzle (9), the switch-off time can be set to a slower or faster value.
The pressure limiting function is thus not influenced.
