· 自動補償平衡式雙平板閘閥/Z44、Z64雙平板閘閥

· 產品結構特點Products design features 

    自動補償平衡式雙平板閘閥是一種結構新穎的閘閥產品，它具有啟閉力矩小、速度快、振動小、使用壽命長、操作安全可靠等特點主要用于氣、液體輸送管道的切斷或泄放。

　　Auto compensation balanced double parallel gate valve is a Producf with new st rucfu re which has small open-and-close moment，high speed，little vibration，long performance life and reliable ope ration，It is mainly applied to cut-off or discharge of gas and liauid delivery Pipelines.

系列平行式雙閘閥結構特點為：
　　The structural features include：
　　閥門采用兩塊互相平行的閘板及其楔緊裝置組成的密封結構取代傳統(tǒng)的楔式閘閥結構。
　　A sealing s ructure consists of two parallel shutters and a wedge-tightening device it is taken to replace the traditional wedg eshaped gate valve structure;
　　閥門密封機構各零件互相分離，即使在溫度變化時引起變形也仍能保證密封，且不會因高溫膨脹而使閘板擠住打不開。
　　The components of valve sealing mechanism are separated so the sealing can retain when transmuting caused by the temperature changes，and willnot jam where swelling in high temperature；
　　閥門密封采用耐磨、耐腐蝕材料制成，延長了閥門的使用壽命。
　　The sealing surface of the valve adopts abrasion-resistant and anti-corrosive mate rials which can lengthen the performance life of the valve;

在高溫、高壓情況下，進口一側閘板設計為可泄壓方式，防止由于溫度變化而引起的腔內壓力異常升高的現象，保證使用安全。

In high temperature or Pressure，the disc on inlet side can be designed in Pressure relief style which can avoid abnormal Pressure rising in cavity caused by temperature changes，thus to ensure used safety;

全封閉結構，防護性能好，可全天候使用。

　　The valve adopts full-shut structure which has good protection function and can be used in allweather.
