二、進(jìn)口可調(diào)式減壓閥結(jié)構(gòu)特點(diǎn)：

1、閥體采用了全通道、直流式、流線型設(shè)計(jì)。水力損失小，節(jié)能效果好。

2、防止水錘效果好，將緩開、止回速閉、緩閉等消除水錘的技術(shù)一體化，防止開泵不錘和停泵倒流與水錘對(duì)供水管路和水泵的損害。

3、操作方便，無(wú)需為閥門另配電控系統(tǒng)，閥門隨水泵的開啟與停止自動(dòng)并按順序完成控制功能。通過(guò)設(shè)定調(diào)節(jié)閥開度可得到合適的控制參數(shù)。

1. The valve body adopts full channel, direct current and streamline design. The hydraulic loss is small and the energy saving effect is good.

2. The effect of preventing water hammer is good. The technology of eliminating water hammer, such as slow opening, check quick closing and slow closing, is integrated to prevent water hammer from damaging the water supply pipeline and water pump when the pump is not started or stopped and the backflow of the pump and water hammer.

3. It is easy to operate, no need to provide another electric control system for the valve. The valve will automatically and sequentially complete the control function with the opening and stopping of the water pump. The appropriate control parameters can be obtained by setting the opening of the control valve.

三、進(jìn)口可調(diào)式減壓閥工作原理：

當(dāng)管道從進(jìn)水端給水時(shí)，水流過(guò)針型調(diào)節(jié)閥進(jìn)入主閥控制室，出口壓力通過(guò)導(dǎo)管作用到導(dǎo)閥上，當(dāng)出口壓力高于導(dǎo)閥設(shè)定值時(shí)，導(dǎo)閥關(guān)閉，控制室停止排水，此時(shí)主閥控制室內(nèi)壓力升高并關(guān)閉主閥，出口壓力不再升高。

當(dāng)出口壓力降到導(dǎo)閥設(shè)定壓力時(shí)導(dǎo)閥開啟，控制室向下游排水。由于導(dǎo)閥的排水量大于針型調(diào)節(jié)閥的進(jìn)水量，主閥控制室壓力下降，進(jìn)口壓力使主閥開啟。穩(wěn)定狀態(tài)下，控制室進(jìn)水、排水相同，開度不變，出口壓力不變。

調(diào)節(jié)導(dǎo)閥彈簧即可設(shè)定出口壓力。

安裝好此閥后，如果出口壓力值不適合現(xiàn)場(chǎng)要求，則可以通過(guò)如下方法對(duì)此閥進(jìn)行調(diào)節(jié)：首先松開減壓導(dǎo)閥平螺母，然后根據(jù)現(xiàn)場(chǎng)要求用M6內(nèi)六角扳手或順時(shí)針或逆時(shí)針調(diào)節(jié)調(diào)節(jié)螺母。順時(shí)針調(diào)節(jié)減壓導(dǎo)閥上的調(diào)節(jié)螺母時(shí)，出口壓力升高；逆時(shí)針調(diào)節(jié)調(diào)節(jié)螺母時(shí)，出口壓力降低。調(diào)節(jié)到能滿足現(xiàn)場(chǎng)要求后，上好平螺母。

When the pipeline supplies water from the inlet end, the water flows through the needle type regulating valve and enters the control room of the main valve. The outlet pressure acts on the pilot valve through the conduit. When the outlet pressure is higher than the set value of the pilot valve, the pilot valve closes and the control room stops drainage. At this time, the pressure in the control room of the main valve increases and the main valve closes, and the outlet pressure no longer increases.

When the outlet pressure drops to the set pressure of the pilot valve, the pilot valve opens and the control room drains to the downstream. Because the water discharge of the pilot valve is greater than that of the needle type regulating valve, the pressure in the control room of the main valve drops, and the inlet pressure makes the main valve open. In the stable state, the water inlet and drainage of the control room are the same, the opening is unchanged, and the outlet pressure is unchanged.

Adjust the guide valve spring to set the outlet pressure.

After the installation of the valve, if the outlet pressure value is not suitable for the site requirements, the valve can be adjusted by the following methods: first, loosen the flat nut of the pressure reducing pilot valve, and then adjust the adjusting nut with the M6 Allen wrench or clockwise or anticlockwise according to the site requirements. When adjusting the adjusting nut on the pressure reducing pilot valve clockwise, the outlet pressure increases; when adjusting the adjusting nut counterclockwise, the outlet pressure decreases. After adjusting to meet the site requirements, install the flat nut.

四、進(jìn)口可調(diào)式減壓閥描述：

德國(guó)LOCKE洛克進(jìn)口可調(diào)式減壓閥是根據(jù)水力差動(dòng)控制原理或水力先導(dǎo)控制（由減壓先導(dǎo)閥控制主閥）原理，以出口壓力的設(shè)定值為準(zhǔn)，自動(dòng)調(diào)節(jié)閥瓣的開啟度和流量，實(shí)現(xiàn)出口壓力的減壓和穩(wěn)定，并與進(jìn)口壓力的關(guān)聯(lián)度較小，可通過(guò)彈簧調(diào)節(jié)裝置，對(duì)減壓閥出口壓力進(jìn)行有效調(diào)整 。

According to the principle of hydraulic differential control or hydraulic pilot control (the main valve is controlled by the pressure reducing pilot valve) and the set value of the outlet pressure, the locklock imported adjustable pressure reducing valve in Germany can automatically adjust the opening degree and flow of the valve disc, realize the pressure reduction and stability of the outlet pressure, and have a small correlation with the inlet pressure. The outlet pressure of the pressure reducing valve can be adjusted by the spring regulating device The force is adjusted effectively.
