The technical scheme that the utility model is used by solution the problem of set forth above is：
A kind of anti-dropout plug screw, including plug screw seat 1, plug screw lid 2 and locking pin 3, the plug screw seat 1 is comprising seat 11, for tight
Nut 12 and sealing ring 13, the seat 11, it includes internal thread pipeline section 111, straight length 112, the conical surface seal section being wholely set
113 and external screw thread pipeline section 114, plug screw lid 2 is threadedly coupled with internal thread pipeline section 111, standby tight nut 12 and the spiral shell of external screw thread pipeline section 114
Line is connected, and sealing ring 13 is set on external screw thread pipeline section 114, is close to standby tight nut 12 and is realized sealing, the both ends difference of plug screw lid 2
The portion of tightening 21 and auxiliary section 22 are provided with, the end of auxiliary section 22 is provided with conical surface closure end 23, and the conical surface blocks end 23 in screw thread
It is close to offer through duct wall on conical surface seal section 113 inwalls realization sealing, the duct wall of straight length 112 under screwing force effect
Mounting-positioning holes and pod apertures, locking pin 3 insertion mounting-positioning holes in, the outer wall of auxiliary section 22 is offered matches somebody with somebody with locking pin 3
The anticreep groove 15 of conjunction.
Mozzle 14 is provided with described pod apertures, fluid flow direction is guided when mozzle 14 is used to drain the oil.
Described locking pin 3 is bearing pin or screw rod.
It is provided with the described side wall of auxiliary section 22 in aperture 16, and the center line of the aperture 16 and the auxiliary section 22
Heart line is vertical.
The beneficial effects of the utility model are：There is no what the deficiency of anti-drop function was proposed for the traditional plug screw of solution,
Beneficial effect after it is implemented is mainly as follows：（1）Plug screw comes off when effectively can prevent from draining the oil.（2）Prevent that fluid from surprisingly splashing.
（3）Ensure the safe operation of effective recovery, operating personnel and the environment of fluid.
