進(jìn)口閘閥、閘板閥(RBT品牌)
產(chǎn)品介紹:
進(jìn)口閘閥又稱閘板閥或閘門閥,它是通過閘板的升降來控制閥門的啟閉,閘板垂直于流體方向,改變閘板與閥座間相對(duì)位置即可改變通道大小。閘閥只能作全開和全關(guān),不適合作調(diào)節(jié)和節(jié)流。閘板有兩個(gè)密封面,最常用的楔式閘板閥的兩個(gè)密封面形成楔形,楔形角隨閥門參數(shù)而異。閘閥關(guān)閉時(shí),密封面可以只依靠介質(zhì)壓力來密封,即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封,這就是自密封。大部分閘閥是采用強(qiáng)制密封的,即閥門關(guān)閉時(shí),要依靠外力強(qiáng)行將閘板壓向閥座,以保證密封面的密封性。
Import valve or gate valve gate valve, also known as, it is the rise and fall through the gate to open and close the control valve, gate perpendicular to the flow direction, changing the relative position between the gate and the seat can change the channel size. Valve can only be fully open and fully closed, not suitable for regulation and throttle. Gate has two sealing surfaces, the most commonly used wedge gate valve sealing surface to form two wedge-shaped, wedge angle parameters vary with the valve. Valve closed, the sealing surface can only rely on pressure to seal the media, that media pressure will depend on the sealing surface pressure gate to the other side of the seat to ensure the sealing surface of the seal, which is self-sealing. Most of the valve is sealed using force, that the valve is closed, forced to rely on external ram pressure to the valve seat to ensure the sealing surface of the seal.
