產品描述

特殊系列調節閥                                                                                                         Special series regulating valve

DC1521 自力式壓力調節閥                                                                                         DC1521  Self-operated pressure regulating valve

DC1521系列自力式壓力調節閥是不需要任何外加能源,利用被調介質自身能量而自動調節閥的執行產品,該產品的最大特點就是能在無電、無氣的場所使用,同時又節約了能源。壓力設定值在一定范圍內隨意可調,根據調壓方式不同可分為DC1521B系列閥后穩壓型和DC1521K閥前穩壓型,詳情介紹如下:

DC1521 series self-operated pressure regulating valve is an execution product that does not require any external energy and automatically adjusts the valve by using the energy of the medium to be adjusted. The biggest feature of this product is that it can be used in places without electricity and gas, and save energy. . The pressure setting value can be adjusted freely within a certain range. According to different voltage regulation methods, it can be divided into DC1521B series valve regulator type and DC1521K valve front regulator type. The details are as follows:

DC1521B系列閥后穩壓型:

DC1521B series post-valve regulator

    用于控制閥后壓力的調節閥,閥作用方式為壓閉型。其工作原理如下:

    介質由箭頭方向流入閥體,經閥座、閥芯節流后輸出。另一路經取壓管(介質為蒸汽時加冷凝器)被引入執行機構作用于膜片上,使閥芯隨之發生相應的位移,達到減壓、穩壓的目的。如閥后壓力增加,作用于膜片上的力增加,壓縮彈簧,帶動閥芯,使閥門的開度減小,直到閥后壓力下降至設定值為止。同理,如閥后壓力降低,作用在膜片上的力減小,由于彈簧的反作用力,帶動閥芯,使閥門的開度加大,直到閥后壓力上升至設定值為止。

Regulating valve for controlling the pressure behind the valve. The valve action mode is pressure-closing type. It works as follows:

The medium flows into the valve body from the direction of the arrow, and is output after being throttled by the valve seat and the valve core. The other way is through the pressure taking pipe (the condenser is added when the medium is steam) to the actuator to act on the diaphragm, so that the valve core will be correspondingly displaced to achieve the purpose of decompression and voltage stabilization. If the pressure behind the valve increases, the force acting on the diaphragm increases, the spring is compressed, and the valve core is driven to reduce the opening of the valve until the pressure behind the valve drops to the set value. Similarly, if the pressure behind the valve decreases, the force on the diaphragm decreases. Due to the reaction force of the spring, the valve core is driven to increase the valve opening degree until the pressure behind the valve rises to the set value.

C1521K系列閥前穩壓型                                                                                             DC1521K series front valve regulator

    用于控制閥前壓力的調節閥,閥作用方式為壓開型。其工作原理如下:

    介質由箭頭方向流入閥體,經閥座、閥芯節流后輸出。另一路經取壓管(介質為蒸汽時加冷凝器)被引入執行機構作用于膜片上,使閥芯隨之發生相應的位移,達到減壓、穩壓的目的。如閥前壓力增加,作用于膜片上的力增加,壓縮彈簧,帶動閥芯,使閥門的開度增大,直到閥后壓力下降至設定值為止。同理,如閥后壓力降低,作用在膜片上的力減小,由于彈簧的反作用力,帶動閥芯,使閥門的開度減小,直到閥前壓力上升至設定值為止。若閥前壓力小于設定值則該閥一直處于關閉狀態。

 

    Regulating valve used to control the pressure in front of the valve. It works as follows:

    The medium flows into the valve body from the direction of the arrow, and is output after being throttled by the valve seat and the valve core. The other way is through the pressure taking pipe (the condenser is added when the medium is steam) to the actuator to act on the diaphragm, so that the valve core will be correspondingly displaced to achieve the purpose of decompression and voltage stabilization. If the pressure before the valve increases, the force acting on the diaphragm increases, and the spring is compressed to drive the valve core to increase the opening of the valve until the pressure behind the valve drops to the set value. Similarly, if the pressure behind the valve decreases, the force acting on the diaphragm decreases. Due to the reaction force of the spring, the valve core is driven to reduce the opening degree of the valve until the pressure before the valve rises to the set value. If the pressure before the valve is less than the set value, the valve is always closed.
