進口高靈敏度減壓閥德國洛克

一、進口高靈敏度減壓閥描述：

德國LOCKE洛克進口高靈敏度減壓閥由主閥和導閥兩部分組成。主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設定出口壓力、利用膜片傳感出口壓力變化,通過導閥啟閉驅(qū)動活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小，實現(xiàn)減壓穩(wěn)壓功能。

The high sensitivity pressure reducing valve imported from Locke lock is composed of main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, regulating spring and other parts. By adjusting and adjusting the spring pressure to set the outlet pressure, using the diaphragm to sense the outlet pressure change, and driving the piston through the pilot valve to adjust the size of the flow area of the throttle part of the main valve, the pressure reducing and stabilizing function is realized.

三、進口高靈敏度減壓閥結(jié)構(gòu)特點：

同一個閥體上可安裝和互換多個導閥，在穩(wěn)壓的同時，實現(xiàn)溫度控制、上游壓力的控制、遠程的開關控制等。

進口高靈敏度減壓閥此類減壓閥在普通減壓閥基礎上做了以下改進，加大了活塞面積，改變了節(jié)流結(jié)構(gòu)，改變了密封形式，改進了導閥結(jié)構(gòu)和調(diào)節(jié)彈簧形式，從而從以下幾方面提高了產(chǎn)品的性能。

1、提高了對出口壓力變化的傳感效能，提高了靈敏度，大大降低了因上游壓力變化，流量變化等因素引起的壓力偏差。

2、改善了流線分布，降低了噪聲。

3、改進了密封面結(jié)構(gòu)，延長了密封面壽命。

Multiple guide valves can be installed and interchanged on the same valve body, which can realize temperature control, upstream pressure control, remote switch control, etc. while stabilizing the pressure.

The imported high-sensitivity pressure reducing valve has made the following improvements on the basis of the ordinary pressure reducing valve, increased the piston area, changed the throttle structure, changed the sealing form, improved the structure of the guide valve and the form of the regulating spring, thus improving the performance of the product from the following aspects.

1. It improves the sensing efficiency of the outlet pressure change, improves the sensitivity, and greatly reduces the pressure deviation caused by the upstream pressure change, flow change and other factors.

2. The streamline distribution is improved and the noise is reduced.

3. The structure of the sealing surface is improved and the service life of the sealing surface is prolonged.
