In the light of the problems with imported offshore wellhead, such as being bulky and expensive and being inconvenient to mount and maintain, Model HKY65―21 offshore wellhead is developed. This wellhead consists of tubing head assembly, PHK plate gate valve, safety valve, stop valve, clamp, small four-way connection and choke, and it is small-sized, light-weighted, high-strength, corrosion- and abrasion-resistant, reliably sealed and convenient to mount and maintain. Application shows that the wellhead can satisfy the requirements of offshore production with good performance.

针对海上油田所用国外采油井口装置存在体积庞大笨重、价格昂贵以及与国产设施不配套和安装维护不便等问题，研制了HKY65―21型海上井口装置这种井口装置主要由油管头总成、PHK平板闸阀、井口安全阀、截止阀、卡箍总成、小四通和节流器组成，具有体积小、重量轻、强度高、防腐耐磨、密封可靠和安装维护方便等优点现场使用128套的实践表明，其各项技术性能指标均能满足海洋石油生产的要求，完全可以取代进口产品，经济效益可观

Use full flow ball or gate valves only.

只选用全通道球阀或闸阀。

The drawback is that operating torque, operation, easy to make body, stem damage, especially in large-diameter gate valve.

其缺点是操作力矩大，操作时易使阀体、阀杆损坏，特别是大口径闸阀。

The sealed part of the damaged gate or ball valve, the valve must be removed from the pipeline to be repaired or replaced, or even directly to the valve end of life.

而闸阀或球阀密封部分受损时，必须将阀门从管道上拆下才能进行维修或更换，甚至直接将阀门报废。

Soft sealing gate valve body, valve cover using precision casting in metal, a shape, the basic non-mechanical processing, do not use sealed copper ring, saving non-ferrous metals.

软密封闸阀的阀体、阀盖采用精密铸造法铸造，一次成型，基本不机械加工，不使用密封铜环，节约有色金属。

Dielectric properties 1.1 The quality of gas, liquid or mixed states, which are used in different varieties of solenoid valves, patients ZQDF for air, ZQDF-Y for liquid, ZQDF-2 (or -3) for the steam, otherwise easily lead to malfunction.

介质特性 1.1质气，液态或混合状态闸阀分别选用不同品种的电磁阀，例ZQDF用于空气，ZQDF—Y用于液体，ZQDF—2（或-3）用于蒸汽，否则易引起误动作。
