♦节流管汇是控制井涌、井喷，实施油气井压力控制技术的必要设备。
Choke manifold is necessary to control well-kick & blowout and put the pressure control technology on oil/gas well into force。

压井管汇是井控处理装置中必不可少的组成部分：
Kill manifold is a necessary part in well-control assembly, its function includes as follows：
♦向井筒中泵入钻井液，控制油气井压力
to pump drilling fluid into well barrel to control the pressure in oil/gas well.
♦发生井喷时，向井口注入清水，以防燃烧起火
to inject the fresh water into wellhead so as to avoid fire and burn as blowout;
♦井喷起火时，向井筒内注入灭火剂，以助灭火
to inject extinguishant into well barrel as blowout and on fire.

阀的启闭是通过闸板在流体垂直方向上的运动实现的；平板阀只能用于井口流体全开和全关, 不能用于以节流为目的流体调节，能实现流体的双向控制。平板阀的系列类型有：暗杆式平板阀、明杆式平板阀、液动平板阀、双作用平板阀、膨胀板阀。

本喷淋泵主要为石油钻井用泥浆泵配套，其作用是在泵的运转过程中对缸套、活塞进行冲洗和冷却，
其它输送泥浆的场合也可使用该产品。
Spraying pump is a kind of equipment especislly matched for mud pump for oil drilling,with the function of
flushing and cooling sleeve and pistons in the procdess of pump operation,as well as include the other situation for
transportation mud.

该泵是针对抽送钻井液或工业悬浮（渣浆）而设计的，可抽送磨蚀、粘滞（性）及腐蚀等液体。同普通泵相比，具有性能优良、流量大、耐高温、使用寿命长、易于维修、可靠性高、节能效果显著等特点，目前广泛用于世界各地陆地和海上钻井。我们将为用户提供最优的产品，以满足不同工况的需求。
