Coding in accompanying drawing is respectively：1 is support tube, and 2 be position-arresting disk, and 3 be upper thread segment, and 4 be lower thread segment, and 5 be spiral shell
Drive sleeve is revolved, 6 be plunger pump, and 7 be liquid feed valve, and 8 be screw thread groove, and 9 be bolt, and 10 be swing handle, and 11 be outer convex edge.
Embodiment
The present invention is not limited by following embodiments, can technique according to the invention scheme and actual conditions it is specific to determine
Embodiment.
In the present invention, for the ease of description, the description of the relative position relation of each part is according to Figure of description 1
Butut mode be described, such as：The position relationship of forward and backward, upper and lower, left and right etc. is the cloth according to Figure of description 1
Figure direction determines.
With reference to embodiment and accompanying drawing, the invention will be further described：
As shown in Figure 1, the plunger pump liquid feed valve provision for disengagement includes connecting rod, opening down and internal diameter is more than liquid feed valve 7
The support tube 1 of external diameter, connecting rod include screw rod and the position-arresting disk 2 being fixed on outside screw rod bottom, and screw rod is divided into top by position-arresting disk 2
Upper thread segment 3 and bottom can be fixedly mounted on lower thread segment 4 in the screw thread groove 8 of liquid feed valve 7, upper thread segment 3 and under
The thread rotary orientation of thread segment 4 is on the contrary, upper thread segment 3 passes through the top middle portion of support tube 1, the upper screw thread outside the top of support tube 1
Section 3 is installed with worm drive set 5, is installed with what can be fixedly installed togather with plunger pump 6 in the lower end of support tube 1
Attachment means.
The support tube 1 of the present invention is fixedly mounted on the body of plunger pump 6 by attachment means, the bottom of lower thread segment 4
The screw thread groove 8 for the liquid feed valve 7 being aligned on the body of plunger pump 6, by rotating screw drive sleeve 5, moves down connecting rod, lower screw thread
Section 4 is threaded into screw thread groove 8, lower thread segment 4 is fixedly mounted in screw thread groove 8, is being entered when the bottom of position-arresting disk 2 is held out against
During the upper surface of liquid valve 7, worm drive of stopping the rotation set 5；Then worm drive set 5 is reversely rotated, moves up connecting rod, and
Drive liquid feed valve 7 to move up, until liquid feed valve 7 is moved fully into from plunger pump 6 in support tube 1, thus complete the liquid feed valve of plunger pump 6
7 dismantlement work.
The setting of support tube 1, the contact area of the bottom surface of support tube 1 and the body of plunger pump 6 can be increased, make support tube 1 steady
Admittedly linked together with plunger pump 6, make the present invention in unloading process, it is not easy to shake, avoid and rock to this hair
Damage caused by bright.
And it is simple to operate, it is detachable liquid feed valve 7 by rotating screw drive sleeve 5, even if operational error, will not also makes
It is injured into operator.
The setting of position-arresting disk 2, it can prevent from excessively screwing worm drive set 5, so as to avoid to lower thread segment 4 and feed liquor
The damage of connection screw thread between the screw thread groove 8 of valve 7.
June in year is dismantled using the present invention to No. 1 dismounting maintenance of water injecting pump liquid feed valve 7 of Tarim Basin Ba Shituo oil gathering stations
Single liquid feed valve 7 average 10 minutes used times, and when being dismantled using its kit, it is averagely time-consuming 30 minutes, therefore, use
The present invention can greatly shorten the take-down time, and unloading process is safe, laborsaving, practical.
From described above, the present invention is not only less likely to occur to rock, and avoids and rocks the damage to caused by the present invention；
And the take-down time can be greatly shortened, unloading process is safe, laborsaving, practical.
Above-mentioned plunger pump liquid feed valve provision for disengagement can be made further optimization and/or improvements according to being actually needed：
As shown in Figure 1, the outer convex edge 11 that bottom surface flushes with the bottom surface of support tube 1 is fixed with outside the lower end of support tube 1, in evagination
Circumferentially interval is installed with least two attachment means along 11.
As shown in Figure 1, attachment means are bolt 9, and screwed hole, bolt 9 are circumferentially arranged at intervals with outer convex edge 11
It is fixedly mounted in screwed hole.
Connect, be easy to support tube 1 and plunger pump due to coming with threaded connection hole on plunger pump 6, therefore using bolt 9
6 are fixed together.
As shown in Figure 1, the top middle portion of support tube 1 is provided with the through hole of up/down perforation, upper thread segment 3 passes through gap
Fit through through hole.
The setting that gap coordinates, make when using the liquid feed valve 7 of present invention dismounting plunger pump 6, can further reduce this
Invent the possibility rocked.
As shown in Figure 1, worm drive set 5 is in hexa-prism.
5 setting is covered in the worm drive of hexa-prism, is easy to screw worm drive set 5 using instruments such as standard wrench.
As shown in Figure 1, it is fixed with swing handle 10 in the upper outside of worm drive set 5；Or in worm drive set 5
Lower outside is fixed with swing handle 10.
Swing handle 10 is used to cover 5 power-assisteds to screw worm drive, makes the operation for screwing worm drive set 5 more quick and saves
Power.
Can be that spiral shell is screwed using spanner when swing handle 10 to be arranged on to the upper outside or lower outside of worm drive set 5
Rotation drive sleeve 5 provides enough operating spaces, is easy to the power-assisted of swing handle 10.
Above technical characteristic constitutes highly preferred embodiment of the present invention, and there is stronger adaptability and optimal implementation to imitate for it
Fruit, can be according to the non-essential technical characteristic of increase and decrease be actually needed, to meet the needs of different situations.
