由于安全閥是一種自動閥門，在結構和性能參數方面與通用閥門有許多不同之處。有些的名詞術語易于混淆，為了使廣大用戶更清楚地了解安全閥，并能正確選用，以下將一些主要名詞術語予以說明。

1、 安全閥名詞術語

（1）安全閥。一種自動閥門。它不借助任何外力，而是利用介質本身地力來排出一額定數量的流體以防止系統內壓力超過預定的安全值；當壓力恢復正常后，閥門再行關","HitNumber":"3693","Sort":"0","ID":"4484","CompanyID":"64727","PgID":"64","ProductsID":"1588753","MarketTime":"2015/8/5 0:00:00","Innovation":"新品上市*","UpdateTime":"2015/8/12 11:29:58","IsShow":"1","CreateTime":"2015/8/12 11:29:58","StandUrl":"/st64727","Address":"美國","MarketPrice":"0","ProvinceID":"24","CityID":"394","IsCharges":"0","CompanyLink":"","CompanyTypeId":"1","ClientClassID":"306803","CityName":"上海","ProvinceName":"上海","CompanyName":"美國漢諾威閥門有限公司","PackageName":"試用會員","ChargesBeginTime":"2015/8/11 0:00:00","PsOrder":"0","FeedBackMsg":"","ResNum":"0","AttType":"0","AttState":"0","AttAddType":"0","BrandNameCH":"","IsOnlinePay":"0","MaxBuyCount":"0","MinPrice":"0.00","MaxPrice":"0.00","trade_productAddress":"","Tag":"進口內螺紋彈簧式安全閥,漢諾威進口內螺紋彈簧式安全閥","Reprint":"","UserID":"73679","TelPhone":"86-21-51602387","Column1":"395","Year":"11"},{"ProID":"1588778","Type":"","Name":"美國漢諾威進口流量調節閥廠家報價","ClassID":"3390","Picture":"6f537ace7514cef61f0d8d22729ee48a194d4b7c4d6cf044e6bae6543f2ed8689621d566fd04be2b.jpg","PictureDomain":"img66","Company":"美國漢諾威閥門有限公司","Descrip":"美國漢諾威進口流量調節閥廠家報價

）防止閃蒸和空化

閃蒸和空化只產生在液體介質。在實際生產過程中，閃蒸和空化會形成振動和噪聲，縮短閥門的使用壽命，因此在選擇閥門時應防止閥門產生閃蒸和空化。

調節閥執行機構

為了使調節閥正常工作，配用的執行機構要能產生足夠的輸出力來保證高度密封和閥門的開啟。

對于雙作用的氣動、液動、電動執行機構，一般都沒有復位彈簧。作用力的大小與它的運行方向無關，因此","HitNumber":"3785","Sort":"0","ID":"4483","CompanyID":"64727","PgID":"64","ProductsID":"1588778","MarketTime":"2015/8/12 0:00:00","Innovation":"新品上市*","UpdateTime":"2015/8/12 11:29:36","IsShow":"1","CreateTime":"2015/8/12 11:29:36","StandUrl":"/st64727","Address":"美國","MarketPrice":"0","ProvinceID":"24","CityID":"394","IsCharges":"0","CompanyLink":"","CompanyTypeId":"1","ClientClassID":"306802","CityName":"上海","ProvinceName":"上海","CompanyName":"美國漢諾威閥門有限公司","PackageName":"試用會員","ChargesBeginTime":"2015/8/11 0:00:00","PsOrder":"0","FeedBackMsg":"","ResNum":"0","AttType":"0","AttState":"0","AttAddType":"0","BrandNameCH":"","IsOnlinePay":"0","MaxBuyCount":"0","MinPrice":"0.00","MaxPrice":"0.00","trade_productAddress":"","Tag":"流量調節閥,進口流量調節閥,漢諾威進口流量調節閥","Reprint":"","UserID":"73679","TelPhone":"86-21-51602387","Column1":"395","Year":"11"},{"ProID":"1588809","Type":"","Name":"美國進口漢諾威流量調節閥概述","ClassID":"3395","Picture":"6f537ace7514cef61f0d8d22729ee48a04cd678f8aabe59447fad40d3bb169d76f4810277159bde4.jpg","PictureDomain":"img66","Company":"美國漢諾威閥門有限公司","Descrip":"美國進口漢諾威流量調節閥概述

閥體類型

進口調節閥的閥體種類很多，常用的閥體種類有直通單座、直通雙座、角形、隔膜、小流量、三通、偏心旋轉、蝶形、套筒式、球形等。

在具體選擇時，可做如下考慮：

（1）閥芯形狀結構

主要根據所選擇的流量特性和不平衡力等因素考慮。

（2）耐磨損性

當流體介質是含有高濃度磨損性顆粒的懸浮液時，閥的內部材料要堅硬。","HitNumber":"2993","Sort":"0","ID":"4482","CompanyID":"64727","PgID":"64","ProductsID":"1588809","MarketTime":"2015/8/12 0:00:00","Innovation":"新品上市*","UpdateTime":"2015/8/12 11:29:20","IsShow":"1","CreateTime":"2015/8/12 11:29:20","StandUrl":"/st64727","Address":"美國","MarketPrice":"0","ProvinceID":"24","CityID":"394","IsCharges":"0","CompanyLink":"","CompanyTypeId":"1","ClientClassID":"306802","CityName":"上海","ProvinceName":"上海","CompanyName":"美國漢諾威閥門有限公司","PackageName":"試用會員","ChargesBeginTime":"2015/8/11 0:00:00","PsOrder":"0","FeedBackMsg":"","ResNum":"0","AttType":"0","AttState":"0","AttAddType":"0","BrandNameCH":"","IsOnlinePay":"0","MaxBuyCount":"0","MinPrice":"0.00","MaxPrice":"0.00","trade_productAddress":"","Tag":"美國進口流量調節閥,漢諾威調節閥尺寸","Reprint":"","UserID":"73679","TelPhone":"86-21-51602387","Column1":"395","Year":"11"},{"ProID":"1588880","Type":"NQ-DWJZF","Name":"漢諾威NQ-DWJZF不銹鋼低溫截止閥結構","ClassID":"3222","Picture":"6f537ace7514cef61f0d8d22729ee48a4f90fcae2756cb110e8b940e08116674829b6252684955da.jpg","PictureDomain":"img67","Company":"美國漢諾威閥門有限公司","Descrip":"漢諾威NQ-DWJZF不銹鋼低溫截止閥結構

1、中心密封蝶閥：

結構特征為閥桿軸心、蝶板中心、本體中心在同一位置上。 結構簡單、制造方便。常見的襯膠蝶閥即屬于此類。缺點是由于蝶板與閥座始終處 于擠壓、刮擦狀態、阻距大、磨損快。為克服擠壓、刮擦、保證密封性能、閥座基 本上采用橡膠或聚四氟乙烯等彈性材料、但也因而在使用上受到溫度的限 制、這就 是為什么傳統上人們認為蝶閥不耐高溫的原因。
