我队金刚石钻进开始时所用水龙头为大口径的，体积与重量都很大，在高转数情况下，造成很大的离心力，影响立轴钻杆的稳定性。针对这一情况，我们设计了一种适应于600米以内钻孔用的小口径水龙头（见图）。通过两年多的使用，效果较好。其特点是：外径小（最大外径为94毫米），重量轻（9.8公斤）。仍采用塞线作为密封填料，塞线的压紧是通过调节螺杆（14）将压力传到塞线压紧套（12），达到塞线压紧密封。为了适应开孔时有时要用卡料卡取岩心，在水龙头上部仍保留投卡料的通孔，只要将丝堵（16）与调
The faucet used by our team at the beginning of diamond drilling is of large caliber, both in volume and weight. At high revolutions, it causes great centrifugal force and affects the stability of vertical drilling rod. In response to this situation, we have designed a small-caliber faucet for drilling holes up to 600 meters (see photo). Through more than two years of use, the effect is better. Its characteristics are: small outer diameter (maximum diameter of 94 mm), light weight (9.8 kg). Sealant is still used as a packing, and the plug is pressed tightly to the plug-in sleeve (12) by adjusting the screw (14) to seal the plug. In order to adapt to the opening hole sometimes use card material to take the core, the upper part of the faucet still retains the feed material through-hole, as long as the plugging (16) and transfer
