什么叫加注閥:本發(fā)明涉及一種用于控制貯液容器如貯水器的充液工作的加注閥。此加注閥通過使****液流量經(jīng)過該閥直到容器被充滿時(shí)瞬時(shí)關(guān)閉加注閥而縮短了容器的充液時(shí)間。此加注閥包括一個(gè)裝在一個(gè)用于決定容器內(nèi)的液面高度的浮子臂相連的閥桿上的移動(dòng)閥頭。閥頭設(shè)置在一個(gè)具有使液流經(jīng)過閥頭而在閥頭后產(chǎn)生背壓的槽的外罩內(nèi)。閥桿封柱了經(jīng)過閥頭的流道,所述閥頭在閥啟閉時(shí)用作導(dǎo)閥。加注閥包括:一個(gè)帶有一個(gè)閥座的閥殼;用于垂直移動(dòng)的浮子機(jī)構(gòu);其一端與所述浮子機(jī)構(gòu)相連而其另一端與所述閥殼可轉(zhuǎn)動(dòng)地相連的致動(dòng)機(jī)構(gòu);以及一個(gè)可移動(dòng)地安裝在所述閥殼中且在關(guān)閉狀態(tài)下位于所述閥座上的閥組件,所述閥組件包括一個(gè)閥頭和一個(gè)具有第一端和第二端的閥桿,所述第一端與所述閥頭接合,而所述第二端與所述致動(dòng)機(jī)構(gòu)相連,其特征在于,當(dāng)所述浮子機(jī)構(gòu)垂直下移時(shí),所述致動(dòng)機(jī)構(gòu)與所述閥桿的所述第二端接合并將閥桿向內(nèi)推入所述閥殼中,由此促進(jìn)了所述閥頭離開所述閥座并開啟所述加注閥。
What is a filling valve: The present invention relates to a filling valve for controlling the filling operation of a liquid storage container such as a water storage container. This filling valve shortens the filling time of the container by instantly closing the filling valve when the * * liquid flow passes through the valve until the container is filled. This filling valve includes a movable valve head mounted on a valve stem connected to a float arm used to determine the liquid level in the container. The valve head is located inside an outer casing with a groove that generates back pressure after the liquid flow passes through the valve head. The valve stem seals the flow channel through the valve head, which serves as a guide valve during valve opening and closing. The filling valve includes: a valve housing with a valve seat; Float mechanism for vertical movement; An actuating mechanism connected to the float mechanism at one end and rotatably connected to the valve housing at the other end; And a valve assembly that is movable and installed in the valve housing and located on the valve seat in the closed state, the valve assembly comprising a valve head and a valve stem having a first end and a second end, wherein the first end is engaged with the valve head, and the second end is connected to the actuating mechanism, characterized in that when the float mechanism moves vertically downward, the actuating mechanism is engaged with the second end of the valve stem and pushes the valve stem inward into the valve housing, thereby promoting the valve head to leave the valve seat and open the filling valve.
3.朝陽(yáng)龍門加工中心車床加工_不銹鋼閥座加工,在液壓控制中,閥控和泵控有什么區(qū)別,各有什么優(yōu)缺點(diǎn):在液壓控制中,使用閥控時(shí),使用的是定量油泵,由溢流閥確定工作壓力,由各種工作閥門輸入的油量基本就不能改變了,工作速度只能分檔調(diào)節(jié),比較低檔的就是一個(gè)工作速度。 泵控是使用比較高級(jí)的變量油泵,除了必要的控制閥門,油泵的變量,提供了更多的速度等工況的調(diào)節(jié)空間。 泵控的設(shè)備、技術(shù)比較高級(jí),當(dāng)然造價(jià)也高。
