底部出口調(diào)流調(diào)壓閥General 概況
In Bottom Outlet (BO) a gate chamber will be erected. The gate chamber shall be equipped with two steel lined waterways. The waterways shall be provided with upstream arranged maintenance gates and downstream arranged service gates. The service gates shall be of sliding gate type, for operation in partial opening position for regulating discharge. The maintenance gates shall be of roller gate type for normal operation in balanced conditions (without flow). Only in emergency cases the gates will be operated in flow condition, but only in fully open or fully closed (no partial opening). The gates shall be operated by hydraulic hoist system.
在底部出口處（BO）應(yīng)建立一個(gè)閘室。閘室應(yīng)配備兩個(gè)鋼內(nèi)襯水道。這兩個(gè)水道上應(yīng)配備上游和下游維護(hù)閘門。這些維護(hù)閘門應(yīng)為滑動(dòng)式，用于調(diào)節(jié)排放量的部分開放位置操作。，維修閘門應(yīng)為輥閘型，便于在平衡條件下（無流量）的正常操作。只有在緊急情況下，這些閘門方可在流量條件下進(jìn)行操作，而且只能為全開或全閉（不得局部開放）。這些閘門應(yīng)當(dāng)由液壓?jiǎn)㈤]系統(tǒng)進(jìn)行操作。 活塞式調(diào)流調(diào)壓閥是液位自動(dòng)控制閥門，是一種流體控制設(shè)備，主要控制其開啟、閉合從而達(dá)到通、斷和控制流量、壓力的作用。
 活塞式調(diào)流調(diào)壓閥利用液壓傳動(dòng)原理來進(jìn)行操控。為達(dá)到閥門性能上的要求，從而利用管道中的流體作為液壓傳動(dòng)介質(zhì)，其中不需要獨(dú)立的液壓泵站，既節(jié)約設(shè)備成本，又節(jié)約能源消耗，以能達(dá)到自動(dòng)控制和調(diào)流減壓的目的。
  活塞式調(diào)流調(diào)壓閥是以管道介質(zhì)壓力為動(dòng)力，進(jìn)行啟閉、調(diào)節(jié)的閥門。是由一個(gè)主閥和附設(shè)的導(dǎo)管、針閥、球閥和壓力表等組成、根據(jù)使用的目的、功能場(chǎng)所的不同，可演變成單獨(dú)的個(gè)體閥門，如調(diào)流閥、減壓閥、水利控制閥、流量控制器、泄壓閥、水泵控制閥等。主閥隨介質(zhì)的液位和壓力的變化而動(dòng)作，可根據(jù)不同使用情況，進(jìn)行單獨(dú)使用或組合使用，從而使主閥獲得對(duì)水位、水壓、流量等進(jìn)行單獨(dú)和復(fù)合調(diào)節(jié)的功能。

活塞式調(diào)流調(diào)壓閥特點(diǎn)：
1、閥體具有壓力損失小、力量大、且抗汽蝕能力強(qiáng)等特點(diǎn)；
2、克服傳統(tǒng)閥門因壓力、流量急劇變化而產(chǎn)生振動(dòng)，噪音大及薄膜容易破損的缺點(diǎn)；
3、機(jī)構(gòu)內(nèi)設(shè)置有彈簧能防止流體壓力流量的急劇變化時(shí)所產(chǎn)生的振動(dòng)，并在無流量時(shí)自動(dòng)關(guān)閉閥門，防止介質(zhì)倒流。
  雖然活塞式調(diào)流調(diào)壓閥產(chǎn)品本身優(yōu)點(diǎn)很多，但是也要根據(jù)使用場(chǎng)合和環(huán)境進(jìn)行選擇。
用戶在選擇流體設(shè)備閥門的時(shí)候，應(yīng)注意到以下一個(gè)方面的問題：
1：工程式中應(yīng)用的閥門是否檢驗(yàn)合格，標(biāo)識(shí)是否齊全，技術(shù)資料是否完備；
2：在安裝前應(yīng)做強(qiáng)度和嚴(yán)密性試驗(yàn)；
3：確定閥門的閥體和密封部位的材質(zhì)，密封性能是否符合要求；
4：在工作情況下，管道輸送的介質(zhì)工作壓力應(yīng)小于閥門的公稱壓力值；
5：如何安裝活塞式調(diào)流調(diào)壓閥，從而方便管理、操作、安裝和維修；
6：閥門法蘭連接管段等容易存氣段，應(yīng)安裝排氣閥.
   在作用上，活塞式調(diào)流調(diào)壓閥是利用水力控制閥的自身壓力及液壓系統(tǒng)操作，進(jìn)行自動(dòng)控制，自動(dòng)過程中動(dòng)作準(zhǔn)確、性能可靠，活塞式調(diào)流調(diào)壓閥在生活生產(chǎn)及消防給水系統(tǒng)管道中起控制、調(diào)流、減壓、確保安全的作用。
