一、進(jìn)口自力式閥前壓力調(diào)節(jié)閥描述：

德國《LOCKE》洛克進(jìn)口自力式閥前壓力調(diào)節(jié)閥，無需外加能源，利用被調(diào)介質(zhì)自身能量為動力源引入執(zhí)行機(jī)構(gòu)控制閥芯位置，改變兩端的壓差和流量，使閥前壓力穩(wěn)定在所需要的閥前壓力值的調(diào)節(jié)閥。LOCKE自力式閥前壓力調(diào)節(jié)閥具有動作靈敏，密封性好，閥前壓力設(shè)定點(diǎn)波動力小等優(yōu)點(diǎn)，廣泛應(yīng)用于氣體、液體及蒸汽介質(zhì)減壓穩(wěn)壓或泄壓穩(wěn)壓的自動控制。

Germany "locke" imported self operated pressure regulating valve in front of the valve, without additional energy, uses the energy of the regulated medium as the power source, introduces the actuator to control the valve core position, changes the pressure difference and flow at both ends, and makes the pressure in front of the valve stable at the required value in front of the valve. Lock self operated pressure regulating valve in front of the valve has the advantages of sensitive action, good sealing and small wave force at the set point of the pressure in front of the valve. It is widely used in the automatic control of pressure reduction and pressure stabilization of gas, liquid and steam media.

三、進(jìn)口自力式閥前壓力調(diào)節(jié)閥工作原理：

工作介質(zhì)的閥前壓力P1經(jīng)過閥芯、閥座后的節(jié)流后，變?yōu)殚y后壓力P2。同時P1經(jīng)過控制管線輸入到執(zhí)行器的上膜室內(nèi)作用在頂盤上，產(chǎn)生的作用力與彈簧的反作用力相平衡，決定了閥芯、閥座的相對位置，控制閥前壓力。當(dāng)閥前壓力P1增加時，P1作用在頂盤上的作用力也隨之增加。此時，頂盤的作用力大于彈簧的反作用力，使閥芯向離開閥座的方向移動，直到頂盤的作用力與彈簧的反作用力相平衡為止。這時，閥芯與閥座的流通面積增大，流阻變小，從而使P1降為設(shè)定值。同理，當(dāng)閥前壓力P1降低時，作用方向與上述相反。

The pre valve pressure P1 of the working medium changes to the post valve pressure P2 after throttling the valve core and valve seat. At the same time, P1 is input to the upper membrane chamber of the actuator through the control pipeline and acts on the top plate. The force generated is balanced with the reaction force of the spring, which determines the relative position of the valve core and valve seat, and controls the pressure in front of the valve. When the pressure P1 in front of the valve increases, the force of P1 acting on the top plate also increases. At this time, the force of the top plate is greater than the reaction force of the spring, so that the valve core moves away from the valve seat until the force of the top plate is balanced with the reaction force of the spring. At this time, the flow area between the valve core and the valve seat increases, and the flow resistance decreases, so that P1 decreases to the set value. Similarly, when the pressure in front of the valve P1 decreases, the action direction is opposite to the above.
