Disclosed are a fusiform self-locking control valve and a fusiform self-locking jet-flow control device, wherein a two-way fusiform selecting and sealing seat is formed by means of a valve core sealing seat (104) and a valve core seat (102), and a valve core (2) can move in a valve core chamber (106) under the acting force of a fluid, and create self-locking and sealing by cooperating respectively with a valve core seat channel (102a) in the valve core seat (102) and a push rod chamber (104a) in the valve core sealing seat (104), thereby preventing fluid leakage, while facilitating independent servicing of one side of the valve core seat channel or one side of the push rod chamber.

一种梭形自锁控制阀及梭形自锁射流控制装置,通过阀芯密封座(104)与阀芯座(102)构成双向梭形选择密封座,阀芯(2)可在流体的作用力下在阀芯腔(106)内移动,并分别和阀芯座(102)上的阀芯座通道(102a)和阀芯密封座(104)上的推杆腔(104a)配合形成自锁密封,防止流体泄漏,又便于单独对阀芯座通道一侧或推杆腔一侧进行检修。
