Embodiment Construction

[0043] Such as figure 1 As shown, a kind of oil well oil well pump that opens the valve valve, the lower end of the pump is a fixed support seat 21, in order to fix the sealing of the valve seat 19, the fixed support seat 21 is connected with the valve sleeve 20 with a screw thread, and the fixed valve Seat 19 is compressed, and described fixed valve seat 19 and fixed valve ball 18 are contacted and sealed, and fixed valve ball 18 is limited in the valve sleeve.

[0044] Such as figure 1 , figure 2 , image 3, Figure 4 , Figure 7 As shown, the ball dial 17 is loaded between the fixed valve ball 18 and the sleeve 20, the ball dial 17 has a certain activity space, and the ball dial 17 is sleeved on the board mouth 30 through the valve cover 16. On the hanging plate post 24 of the movable joint push rod 15, the ball dialing plate 17 is provided with an anti-stalking step 23 on it.

[0045] Such as figure 1 , image 3 , Figure 5 , Figure 6 As shown, the movable mand...

Abstract

The invention provides an oil well pump draining liquid by opening valve balls. When a piston is in the pump and liquid needs to be drained, the piston presses down an articulated ejector rod, the articulated ejector rod is lengthened and pushes a ball moving plate, the ball moving plate opens a fixed valve ball, a ball pushing cylinder on the piston simultaneously pushes up a lower travelling valve ball, the lower travelling valve ball pushes up a ball pushing rod and the ball pushing rod pushes up an upper travelling valve ball, thus completing drain of the liquid above the valve balls into a well. When the piston is not in the well and liquid needs to be drained, a weighing rod presses down the articulated ejector rod, the articulated ejector rod is lengthened and drives the ball moving plate to open the fixed valve ball, thus completing drain of the liquid above the fixed valve ball into the well. During oil pumping production, the piston does not come into contact with the articulated ejector rod, thus not affecting sealing of the valve balls and valve seats; after the valve balls are opened, conventional well-flushing to remove paraffin can be completed; when the oil well pump is overhauled, the valve balls are opened to drain liquid, thus preventing the liquid in the well from being brought to the ground, protecting the environment and also reducing the labor intensity of operators.

Description

technical field [0001] The invention relates to an oil well pump, which belongs to the technical field of oil field downhole tools, and in particular relates to the technical field of tubular oil pumps. Background technique [0002] There are many kinds of known oil well oil well pumps, especially the tube type oil well pumps, which have the disadvantage of not being able to drain liquid. Contents of the invention [0003] In order to overcome the deficiencies of the existing tubular oil well pumps, the object of the present invention is to provide an oil well pump that opens the valve ball to drain the liquid, and when it is necessary to drain the water, the valve ball and the valve seat are separated to complete the ball valve. The above liquid is discharged into the well. [0004] Disclosed is an open valve ball drain oil well oil pump, which is mainly composed of a jacket and a piston. , valve sleeve, fixed support seat and support spring; the piston is mainly compos...
