進(jìn)口內(nèi)螺紋閘閥品牌德國洛克

 

進(jìn)口內(nèi)螺紋閘閥結(jié)構(gòu)特點(diǎn):

1、結(jié)構(gòu)簡(jiǎn)單，制造和維修比較方便。

2、工作行程小，啟閉時(shí)間短。

3、密封性好，密封面間磨擦力小，壽命較長。

內(nèi)螺紋閘閥的缺點(diǎn)如下：

1、流體阻力大，開啟和關(guān)閉時(shí)所需力較大。

2、不適用于帶顆粒、粘度較大、易結(jié)焦的介質(zhì)。

3、調(diào)節(jié)性能較差。

進(jìn)口內(nèi)螺紋閘閥工作原理:

閘閥的種類 ,按密封面配置可分為楔式閘板式閘閥和平行閘板式閘閥 , 楔式閘板式閘閥又可分為:單閘板式、雙閘板式和彈性閘板式；平行閘板式閘閥可分為單閘板式和雙閘板式。按閥桿的螺紋位置劃分，可分為明桿閘閥和暗桿閘閥兩種。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。

Working principle of inlet internal thread gate valve:
According to the sealing surface configuration, gate valve can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into single gate plate, double gate plate and elastic gate valve. Parallel gate valve can be divided into single gate plate and double gate plate. According to the thread position of the stem, it can be divided into two types: rising stem gate valve and Non rising stem gate valve. When the gate valve is closed, the sealing surface can only be sealed by the medium pressure, that is, the sealing surface of the gate valve is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate should be forced to the valve seat by external force, so as to ensure the tightness of the sealing surface.
                                                                               

進(jìn)口內(nèi)螺紋閘閥產(chǎn)品簡(jiǎn)介:

德國洛克《DE LOCKE》進(jìn)口內(nèi)螺紋閘閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。紋管截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。

Introduction of imported internal thread gate valve
The opening and closing parts of the internal thread gate valve imported from German Locke are plug-shaped disc. The sealing surface is flat or conical, and the disc moves in a straight line along the center line of the fluid. The movement forms of the valve stem include the lifting rod type (the valve stem rises and falls, but the hand wheel does not rise and falls), and the lifting rotary rod type (the hand wheel and the valve stem rise and fall together, and the nut is set on the valve body). The bellows globe valve is only suitable for full opening and full closing, and it is not allowed to adjust and throttle.
