對(duì)于安裝在干管上起切斷作用的閉路閥門，應(yīng)逐個(gè)作強(qiáng)度和嚴(yán)密性的實(shí)驗(yàn)。第二點(diǎn)就是對(duì)于設(shè)計(jì)沒有要求的情況的試驗(yàn)。當(dāng)設(shè)計(jì)有沒有要求閥門的強(qiáng)度和嚴(yán)密性試驗(yàn)，應(yīng)該按以下規(guī)定來進(jìn)行。閥門的強(qiáng)度試驗(yàn)，壓力為公稱壓力的，嚴(yán)密性試驗(yàn)壓力為公稱壓力的，試驗(yàn)壓力在試驗(yàn)持續(xù)時(shí)間內(nèi)不變，并且殼體填料及閥瓣密封面沒有滲漏。第三點(diǎn)我們來看一下各種閥門**短的試驗(yàn)持續(xù)時(shí)間的具體要求。***種情況是金屬密封的閥門，嚴(yán)密性試驗(yàn)的具體要求是直徑小于等于50mm時(shí)，不得小于15秒；直徑為60mm到200mm時(shí)，時(shí)間不得小于30秒；直徑為250mm到450mm時(shí)，時(shí)間不得小于60秒。另外對(duì)非金屬材料的閥門，對(duì)應(yīng)以上的規(guī)格是15秒，15秒和30秒。此外就是強(qiáng)度試驗(yàn)的要求方面，直徑小于等于50mm時(shí)不得小于15秒；它們直徑為60到200mm時(shí)，不得小于60秒；閥門直徑為250mm到450mm時(shí)，不得小180秒。三通恒溫控制閥是一種閥門控制器。無錫冰輪油溫控制閥源頭好貨</p><p

相對(duì)行程和相對(duì)流量間的關(guān)系稱為溫控閥的流量特性，即：G/Gmax=f（l）。它們之間的關(guān)系表現(xiàn)為線性特性、快開特性、等百分比特性、拋物線特性等幾種特性曲線。對(duì)散熱器而言，從水利穩(wěn)定性和熱力是調(diào)度角度講，散熱量與流量的關(guān)系表現(xiàn)為一簇上拋的曲線，隨著流量G的增加，散熱量Q逐漸趨于飽和。為使系統(tǒng)具有良好的調(diào)節(jié)特性，易于采用等百分比流量特性的調(diào)節(jié)閥以補(bǔ)償散熱器自身非線性的影響（1）。閥權(quán)度對(duì)調(diào)節(jié)特性的影響?？烧{(diào)比R為溫控閥所能控制的比較大流量與比較小流量之比：R=Gmax/GminGmax為溫控閥全開時(shí)的流量，也可看作是散熱器的設(shè)計(jì)流量；Gmin則隨溫控閥閥權(quán)度大小而變化。在散熱器系統(tǒng)中，由于溫控閥與散熱器為串聯(lián)，故可調(diào)節(jié)比R與閥權(quán)度的關(guān)系為：R=Rmax（2）以某型號(hào)的溫控閥和散熱器為例，散熱器的流通能力為5m3/h,溫控閥的閥權(quán)度為88%，實(shí)際可調(diào)比為28，對(duì)應(yīng)的流量可調(diào)節(jié)范圍****-4%。散熱器在不同進(jìn)出口溫差下散熱量的實(shí)際可調(diào)節(jié)范圍見表。進(jìn)出口溫度差（℃）可調(diào)節(jié)范圍（%）100~100~100~100~100~28由表可知，當(dāng)散熱器進(jìn)出口溫差較小時(shí)，散熱量的實(shí)際可調(diào)節(jié)范圍也見小。但散熱器進(jìn)出口溫差小于10℃時(shí)，溫控閥的比較小可調(diào)節(jié)散熱量約為標(biāo)準(zhǔn)散熱量的20%。無錫冰輪油溫控制閥源頭好貨</p><p
