Y型快閉式止回閥（DYH41X）用于水泵出口處，在水泵停止時，起快速止回，防止水錘產(chǎn)生的作用。開泵時，閥瓣在水底推力下上升，開啟閥門，同時彈簧被簧力的作用下迅速關(guān)閉，當水流接近于0時，閥瓣完全關(guān)閉。無水倒流現(xiàn)象，同時因水不能倒流，不產(chǎn)生動能，便防止了水錘的產(chǎn)生。其特點：1.防止水錘的產(chǎn)生。2.關(guān)閉無聲音。3.水頭損失小。4.使用范圍廣。5.密封效果好。使用于清水、污水等系統(tǒng)中。二、主要技術(shù)性能： 1. Y型快閉式止回閥主閥體采用Y型膜片式結(jié)構(gòu)，密封副為非金屬密封；閥門一般要求水平安裝，與管道的連接形式為法蘭連接，法蘭連接尺寸按國家標準GB/T17241.6執(zhí)行，湖北止回閥型號及規(guī)格。 2. Y型快閉式止回閥由閥體、閥蓋、中心軸、銅套、閥座、閥瓣等主要零件組成，通過控制閥瓣的上下運動來實現(xiàn)閥門的啟閉，湖北止回閥型號及規(guī)格。三、主要零部件材質(zhì)：零件名稱材質(zhì) 閥體、閥蓋鑄鐵，湖北止回閥型號及規(guī)格、鑄鋼、不銹鋼閥桿鉻不銹鋼閥瓣碳鋼、不銹鋼+丁腈橡膠

球型止回閥通常都是選用橡膠包皮球為閥瓣，其原理是在介質(zhì)的效果下，可在閥體內(nèi)的滑道上前后翻滾，然后起到翻開或封閉閥門。HQ44X單球微阻球形止回閥、HQ45X雙球微阻球形止回閥首要特點是流量大，流阻壓力丟失小，密封性能好，消聲封閉，可減小水擊波。水平或筆直設(shè)備均可。微阻球形止回閥可用于冷水、熱水、工業(yè)及日子污水等管網(wǎng)的水泵出口，避免介質(zhì)倒流。為了避免介質(zhì)逆流，在設(shè)備、設(shè)備和管道上都應(yīng)設(shè)備止回閥。球形止回閥都是采用橡膠包皮球為閥瓣，他們的原理是在介質(zhì)的作用下，可在閥體內(nèi)的滑道上前后滾動，從而起到打開或關(guān)閉閥門。HQ44X單球微阻球形止回閥、HQ45X雙球微阻球形止回閥主要特點是流量大，流阻壓力損失小，密封性能好，消聲關(guān)閉，可減小水擊波，水平或垂直安裝都是可以的。微阻球形止回閥可用于冷水、熱水、工業(yè)及生活污水等管網(wǎng)的水泵出口，防止介質(zhì)倒流，為了防止介質(zhì)逆流，在設(shè)備、裝置和管道上都應(yīng)安裝止回閥。湖北止回閥作用</p><div

style="text-indent:25px">閥門安裝及維護：其中止回閥就屬于這種類型的閥門，它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機構(gòu)，還有一個像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達閥座面的合適位置，閥瓣設(shè)計在鉸鏈機構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、全方面的與閥座接觸。閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在完全打開的狀況***體壓力幾乎不受阻礙，因此通過閥門的壓力降相對較小。升降式止回閥的閥瓣座落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外，其余部分如同截止閥一樣，流體壓力使閥瓣從閥座密封面上抬起，介質(zhì)回流導(dǎo)致閥瓣回落到閥座上，并切斷流動。</p><p style="text-indent:25px">噴塑大口徑軟密封閘閥系列產(chǎn)品的特點是：閘板采用高質(zhì)量進口三元乙丙（EPDM）包覆，具有低變形和良好的彈性，閥體、閥蓋等鑄件采用精密鑄造，整體采用環(huán)氧樹脂噴涂，閥體與閥蓋連接處采用沉頭螺栓連接，外加膠封住，中口采用“O”型密封圈密封，閥桿密封采用先進的設(shè)計，可以做到帶壓更換閥桿密封圈，整個閥門共四處密封，徹底做到無滲漏，具有密封可靠、操作輕便、無污染、耐腐蝕及使用壽命長的特點。閥門通徑底部無凹槽，它克服了傳統(tǒng)的硬密封閘閥的缺點，可以避免泥沙、雜質(zhì)等在底部沉積，而不會導(dǎo)致閥門關(guān)閉困難及密封面損壞。　　噴塑閥門的主要創(chuàng)新點和技術(shù)水平：　　1.噴塑工藝：國內(nèi)廠家噴塑，一般是薄壁件，采用先噴粉，后加熱固化。此工藝不適合于壁厚鑄鐵件。我廠的噴塑工藝吸取了丹麥AVK公司的先進技術(shù)，對鑄件進行先加熱到一定溫度，后噴粉，利用鑄件自身熱量進行固化。噴塑層比一般工藝的噴塑層附著力強，厚度均勻，鑄件噴塑后，表面光潔度好。　　2.產(chǎn)品綠色環(huán)保：閥門與水接觸部分做到健康，無銹蝕，不污染介質(zhì)。　　3.閥門外形美觀。采用全密封設(shè)計，不銹蝕。</p><div

style="text-indent:25px">水利減壓閥的分類：減壓閥的種類很多，但大致可分為直接作用式（自力式）和間接作用式（它力式）兩大類。直接作用式減壓閥，即利用介質(zhì)本身的能量來控制所需的壓力，間接作用式減壓閥，即利用外界的動力，如氣壓、液壓或電氣等來控制所需的壓力。這兩類相比，前者結(jié)構(gòu)比較簡單，后者精度較高。目前，我國大量生產(chǎn)和使用的都是直接作用式減壓閥。根據(jù)減壓閥的結(jié)構(gòu)還可分為：活塞式減壓閥：它是通過活塞來平衡壓力，帶動閥瓣運動。薄膜式減壓閥：采用薄膜作敏感元件來帶動閥瓣運動的減壓閥。氣包式減壓閥：依靠閥后介質(zhì)進入氣包內(nèi)的壓力來平衡壓力的減壓閥。以上的分類方法是根據(jù)減壓閥的結(jié)構(gòu)來分的。如果按減壓閥的閥座形式來分，又可分為單閥座式減壓閥和雙閥座式減壓閥兩種。雙閥座式減壓閥安一方面可使作用在上、下閥座上的力大部分相互平衡而抵消，減小作用在閥桿上的合力；另一方面還可以得到較大的通道面積，同時能減小整個閥門的體積。但雙閥座減壓閥的閥座工藝性不好，湖北止回閥哪家強</p><p
