Preferably, in the reset state, an angle between the tail connecting rod and the middle connecting rod of the reset rod is 60-90 degrees, and in the jacking state, an angle between the tail connecting rod and the middle connecting rod of the reset rod is 135-150 degrees.
Preferably, a centralizing rib structure is arranged in the middle chamber of the valve body.
Preferably, the head connecting rod of the reset rod is a four-folded section rod, two adjacent folded sections are vertical, and the first folded section corresponding to the top end is a horizontal section.
The beneficial effects are that:
1. according to the emergency oil drain valve, when an external sucker rod or an oil pump plunger breaks down, the sucker rod or the oil pump plunger can lift up the valve ball by pressing down the reset rod, so that an oil drain channel is opened, and the purpose of oil drain is achieved; meanwhile, when the oil well pump works normally and needs to be started, the aim of oil drainage can be achieved by throwing an oil drainage rod into the oil well; the emergency oil drain valve can be widely applied to the exploitation of crude oil in an oil well in which a pole is broken, lost and fails or an oil pump fixing valve cannot be salvaged, and can effectively prevent the situation that crude oil in an oil pipe column cannot be discharged to pollute the ground crude oil of a well site when a pump is started.
2. The guide mechanism arranged at the top of the valve body can effectively help the oil drain rod or the plunger of the oil pump to accurately enter the valve body.
3. The four-fold section design of the reset rod can effectively enlarge the range of the action of external force, and is convenient for the external sucker rod or the plunger of the oil pump to fall into the valve body to press down the reset rod; the reset rod can be effectively arranged in the valve body and does not influence the movement of the valve ball.
