詳細介紹
產(chǎn)品介紹:
單閥座:需要克服介質(zhì)壓力對閥座的作用,閥座的孔徑不能很大芽丹,適用于小型設(shè)備北启、伴熱管線,蒸汽主管等排水小的場合拔第。閥座孔設(shè)計在凝結(jié)水水位以下咕村,自然形成水封,水蚊俺、汽自然分離懈涛,達到無蒸汽泄漏,即便沒有凝結(jié)水采用球型密封的杠桿使得閥瓣緊貼閥座泳猬,達到無新鮮蒸汽的泄露批钠。不受凝結(jié)水量波動和溫度的影響。
雙平衡閥座:該閥利用雙閥孔設(shè)計得封,介質(zhì)的壓力對兩個閥座作用相等了岸,方向相反,介質(zhì)壓力對閥座作用相抵消奈揩,閥蕊在開閥時壓力相對減少造蒋,從而獲得超大排量。工作時浮球隨閥腔內(nèi)液體位的變化而上下浮動效蝎,帶動杠桿打開或關(guān)閉閥座牙德。由于閥座孔在凝結(jié)水水位以下,形成水封虎铅,水庭钢、汽自然分離,達到無蒸汽泄漏钟骏。不受壓力讽钻、溫度、冷凝水流量波動的影響企鄙。
Lever-ball float trap
Lever ball float type trap employs the buoyancy principle and the lever principles:to make the ball float ascend or descend by the change in the liquid level and then the ball float drives the lever to make the valve disc from or touch the valve seat to realize drainage and closed block vapor. The product adopts the automatic air exhaust to automatically eliminate non-condensing air.It is very precise with high operating and long service life.It can discharge whenever there is any water,and its minimum subcooled temperature is 0℃.The lever-ball float trap adopts two kinds of structure modes:A:Single valve seat-lever ball float;B:double balanced valve seat-lever ball float.
Single valve seat:it needs to overcome the operation on the valve seat by the medium pressure;the hole caliber of the valve seat cannot be too large and is applicable to such low displacement condition as mini-equipment,steam tracing pipeline and steam main pipe.The hole of the valve seat is designed beneath the water level of the condensate water to form water sealing to keep water apart from vapor,so as to prevent the leakage of the vapor.Though there is no condensate water that uses ball-type sealed lever to make the valve clack tightly adhesion to the valve seat,it can prevent the fresh vapor from leakage.Further,the product is free of the affect of the fluctuation of the condensate water's quantity and temperature.
The double balanced valve seat:this valve is designed to have two valve openings.The pressure of the medium act against the two valve seats equally in reverse direction,so the pressure on the valve seat is offset,the valve core assumes relatively low pressure when the valve is open,in this way the overlarge displacement is obtained.During the operating process,the ball float floats with the change in liquid level of the valve cavity to make the lever open or close the valve seat.The hole of the valve seat is designed beneath the water level of the condensate water to form water sealing to keep water apart from vapor,so as to prevent the leakage of the vapor.Further,the product is free of the affect caused by the fluctuation of pressure,temperature and condensate's flow.優(yōu)點:
1扎矾、采用新型閥機構(gòu)(新 SCCV 關(guān)閉方式和Z型結(jié)構(gòu)),具有優(yōu)良的密封性和耐久性。2唉侄、雙平衡閥座設(shè)計咒吐,比一般的疏水閥體積小而排量大,在特大排量場合更能發(fā)揮*性属划。
3恬叹、單閥座設(shè)計可以水平或垂直安裝,可以滿足高背壓同眯,低排量蒸汽管線绽昼。
4、內(nèi)裝空氣自動排放閥须蜗,可防止空氣氣堵和蒸汽汽鎖硅确。
5、全部部件安裝在閥蓋上明肮,閥無需從配管上卸下菱农,就可維修保養(yǎng),簡單方便柿估。
Merits
1.To use new-style valve mechanism (new SCCV closing mode and Z-shaped structure) to boast excellent tightness and endurance.2.To employ double balanced valve seat design,it has smaller volume and larger displacement and can exert its advantages when needing large displacement.
3.The single valve seat model can be installed horizontally and vertically,satisfying the requirements of steam pipeline with high backpressure and low displacement.
4.The built-in automatic air exhaust can prevent air blocking and steam locking;
5.As all components are installed on the valve cover,so they can be maintained and cleaned up simply and easily without being removed from pipe arrangement.
