產(chǎn)品詳情

用途和適用范圍 Feature and application

自力式壓力調(diào)節(jié)閥(以下簡稱壓力閥)是一種無需外來能源而只依靠調(diào)介質(zhì)自身的壓力變化進(jìn)行自動調(diào)節(jié)壓力的節(jié)能型產(chǎn)品．具有測量、執(zhí)行、控制的綜合功能。廣泛適用于石油、化工、冶金、輕工等工業(yè)部門及城市供熱、供噯系統(tǒng)。本產(chǎn)品可用于非腐蝕性(zui高溫度350℃)的液體、氣體和蒸汽等介質(zhì)的壓力控制裝置。

Pressure self-regulating valve （herein after referred to as pressure valve）, a energy saving product, regulates pressure automatically without external energy supply. Pressure valve is used for pressure control device of non-corrosive liquid, gas and steam medium etc. that has integrated function of measure, performance and control. Pressure valve finds us in the field of petroleum, chemical industry, metallurgy and light industry and city heating system etc..

結(jié)構(gòu)及工作原理 Structure and working principle

產(chǎn)品結(jié)構(gòu) Structure

本產(chǎn)品為直接作用型自力式壓力調(diào)節(jié)閥．由閥體、閥座、閥芯部件、閥蓋、頂盤、上、下膜蓋、膜片、彈簧、調(diào)節(jié)螺母等零部件所組成。

其具體結(jié)構(gòu)參見圖la，圖lb、圖lc、圖ld所示：

Pressure valve is of direct action type, which is composed of body, seat, core parts, bonnet, highest quotation, diaphragm, spring, adjusting nut and upper and bottom diaphragm cover etc..

The specific structure sees chart 1a, 1b, 1c and 1d.

工作原理 Working principle

(I)作閥后壓力調(diào)節(jié)時(shí)的工作原理：(見圖la)

工藝介質(zhì)的閥前壓力Pl經(jīng)過閥芯、閥座的節(jié)流后，變?yōu)殚y后壓力P2。P2經(jīng)過控制管線輸入執(zhí)行器的下膜室作用在頂盤上．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．控制閥后壓力。當(dāng)閥后壓力P2增加時(shí)．P2作用在頂盤上的作用力也隨之增加。此時(shí)．頂盤的作用力大于彈簧的反作用力．使閥芯關(guān)向閥座的位置．直到頂盤的作用力與彈簧反作用力相平衡為止。這時(shí)．閥芯與閥座之間的流通面積減少．流阻變大．從而使P2降為設(shè)定值。同理，當(dāng)閥后壓力P2降低時(shí)．作用方向與上述相反．這就是閥后壓力調(diào)節(jié)時(shí)的工作原理。當(dāng)需要改變閥后壓力P2的設(shè)定值時(shí)．可調(diào)整調(diào)節(jié)螺母8。

(1)The working principle of regulating the back of valve’s pressure :（see chart 1a）

After being throttled by core and seat, P1 becomes P2.（P1 stands for the front of valve’s pressure and P2 stands for the back of valve’s pressure.）Getting through bottom diaphragm room, P2 acts on the highest quotation and creates acting force. The acting force keeps its balance with reacting force of spring, which decides the relative place of core and seat and controls the back of valve’s pressure. When P2 increases, the acting force is also increasing. Here, the acting force is bigger than the reacting force, which made the core close to the seat until balance. And the circulation area between core and seat decreases and flow resistance increases, thereby P2 fell to the setting value. Also, when P2 decreases, the acting force direction is contrary.

When P2 `s setting value needs to be changed, you can regulate the adjusting nut 8.
