進(jìn)口先導(dǎo)式高靈敏度減壓閥產(chǎn)品列表德國洛克 

一、進(jìn)口先導(dǎo)式高靈敏度減壓閥描述：

德國LOCKE洛克進(jìn)口先導(dǎo)式高靈敏度減壓閥是氣動(dòng)調(diào)節(jié)閥的一個(gè)必備配件，主要作用是將氣源的壓力減壓并穩(wěn)定到一個(gè)定值，以便于調(diào)節(jié)閥能夠獲得穩(wěn)定的氣源動(dòng)力用于調(diào)節(jié)控制。

按結(jié)構(gòu)形式可分為膜片式、彈簧薄膜式、活塞式、杠桿式和波紋管式；按閥座數(shù)目可人為單座式和雙座式；按閥瓣的位置不同可分為正作用式和反作用式

先導(dǎo)式超大膜片高靈敏度減壓閥的工作由閥后壓力進(jìn)行控制。當(dāng)壓力感應(yīng)器檢測到閥門壓力指示升高時(shí)，減壓閥閥門開度減?。划?dāng)檢測到減壓閥后壓力減小，減壓閥閥門開度增大，以滿足控制要求。

The pilot type high sensitivity pressure reducing valve imported from Locke lock, Germany, is an essential part of the pneumatic control valve. Its main function is to reduce the pressure of the air source and stabilize it to a fixed value, so that the control valve can obtain stable power of the air source for regulation and control.

According to the structure, it can be divided into diaphragm type, spring diaphragm type, piston type, lever type and bellows type; according to the number of seats, it can be divided into single seat type and double seat type; according to the position of the valve disc, it can be divided into positive acting type and negative acting type

The work of the pilot type super large diaphragm high sensitivity pressure reducing valve is controlled by the pressure behind the valve. When the pressure sensor detects that the pressure indication of the valve increases, the valve opening of the pressure reducing valve decreases; when the pressure decreases after detecting the pressure reducing valve, the valve opening of the pressure reducing valve increases to meet the control requirements.

Pilot type super large diaphragm high sensitivity pressure reducing valve - the pressure reducing ratio of the valve must be higher than the system value to a certain extent; it should be able to respond to the positive or negative action control signal even at the maximum or minimum flow. These valves should be selected for the useful control range, i.e. 20% to 80% of the maximum flow. It is usually of the same ratio type or with the same ratio characteristics. These types of valves themselves have the best flow characteristics and flow range required for proportional control.

二、進(jìn)口先導(dǎo)式高靈敏度減壓閥用途及主要性能：

本閥適用于水、蒸汽、空氣介質(zhì)管路上，通過調(diào)節(jié)使進(jìn)口壓力降低至某一需要的出口壓力，當(dāng)進(jìn)口壓力與流量有變化時(shí)，靠介質(zhì)本身的能量自動(dòng)保持出口壓力在一定范圍內(nèi)，但進(jìn)口壓力和出口壓力之差必須≥0.2MPA/CM

This valve is suitable for water, steam and air medium pipelines. It can reduce the inlet pressure to a certain required outlet pressure by regulating. When the inlet pressure and flow change, the outlet pressure will be kept within a certain range automatically by the energy of the medium itself, but the difference between the inlet pressure and the outlet pressure must be ≥ 0.2mpa/cm

三、進(jìn)口先導(dǎo)式高靈敏度減壓閥結(jié)構(gòu)特點(diǎn)：

同一個(gè)閥體上可安裝和互換多個(gè)導(dǎo)閥，在穩(wěn)壓的同時(shí)，實(shí)現(xiàn)溫度控制、上游壓力的控制、遠(yuǎn)程的開關(guān)控制等。

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.
