Abstract
The utility model relates to a salvageable valve type oil well pump. The salvageable valve type oil well pump is mainly used to solve the problem that the disassembly of a valve ball valve body in the process of valve ball replacement in oil-gas well maintenance is a time-consuming and laborious process in the prior art. The salvageable valve type oil well pump is characterized in that: a support bracket (6) is connected to the top of a fixed valve housing (8), a salvageable valve seat (4) is placed on the upper end of the support bracket (6), a salvageable valve ball (3) is seated on the salvageable valve seat (4), a salvageable valve housing (5) is arranged outside the salvageable valve seat (4) and the salvageable valve ball (3), a salvage head (2) is connected to the top of the salvageable valve housing (5), a groove is opened on the outer periphery of the bottom end of the support bracket (6), and a boss corresponding to the groove on the support bracket (6) is arranged in the middle portion of an inner cavity of a connection component (7). Through the installation of the salvageable valve ball, the salvageable valve type oil well pump can be used to realize that the valve ball valve body is not needed to be disassembled in the process of valve ball replacement in oil well maintenance, so advantages of time saving and effort saving are realized.
Description
Technical field
The utility model relates to a kind of oil well pump in the Oilfield using field, particularly a kind of valve formula oil well pump that drags for.
Background technique
When recovered the oil in the oil field at present, changing the standing valve ball in the oil gas well servicing was a main job content, can't directly change at well head and change valve ball; Must flow string and oil well pump all could be changed after the taking-up; Therefore workload is big and cumbersome, wastes time and energy inefficiency; Increase operating cost, influenced the normal effectively work of oil well.
Summary of the invention
The utility model technical problem to be solved is to overcome the oil gas well servicing that exists in the background technique, must dismantle down the problem that the valve ball valve body is wasted time and energy when changing valve ball; And a kind of valve formula oil well pump that drags for is provided; This can drag for valve formula oil well pump can drag for the valve body through being equipped with; Make workover, needn't dismantle the valve ball valve body when changing valve ball, time saving and energy saving.
The utility model solves its problem and can reach through following technological scheme: this can drag for valve formula oil well pump and comprise urceolus, standing valve; Standing valve is seated on the standing valve seat; Standing valve and standing valve seat outside are equipped with the standing valve shell, and urceolus is connected through link with the standing valve shell, and described standing valve cover top portion is connected with supporting frame; The supporting frame upper end is equipped with can drag for valve seat; Can drag on the valve seat to sit to have and to drag for valve ball, can drag for valve seat and be equipped with and to drag for the valve shell, can drag for the valve cover top portion and be connected to fishing head with dragging for the valve ball outside; Described supporting frame bottom periphery has groove, link inner chamber middle part have with supporting frame on the corresponding boss of groove.
The utility model and above-mentioned background compared with techniques can have following beneficial effect: this can drag for valve formula oil well pump owing to adopting said structure, is lowered to one in maintenance, when changing valve ball and can drags for the standing valve body that the valve body replaces damage, needn't dismantle; Can keep in repair, operation element such as replacing, need oil pipe not proposed during maintenance, reduced operation cost; Shorten the activity duration, reduced cost for oil production, time saving and energy saving; Increase work efficiency, make oil well guarantee normal effectively work.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure: the 1-urceolus, the 2-fishing head, 3-can drag for valve ball, and 4-can drag for valve seat, and 5-can drag for the valve shell, 6-supporting frame, 7-link, 8-standing valve shell, 9-standing valve, 10-standing valve seat.
Embodiment:
To be described further the utility model below in conjunction with accompanying drawing:
Shown in accompanying drawing 1, this can drag for valve formula oil well pump and comprise urceolus 1, standing valve 9; Standing valve 9 is seated on the standing valve seat 10; Standing valve 9 is equipped with standing valve shell 8 with standing valve seat 10 outsides, and urceolus 1 is connected through link 7 with standing valve shell 8, and described standing valve shell 8 tops are connected with supporting frame 6; Supporting frame 6 upper ends place can drag for valve seat 4 bottoms; Can drag on the valve seat 4 to sit to have and to drag for valve ball 3, can drag for valve seat 4 and be equipped with and to drag for valve shell 5, can drag for valve shell 5 tops and be connected to fishing head 2 with dragging for valve ball 3 outsides; Described supporting frame 6 bottom peripheries have groove, link 7 inner chambers middle parts have with supporting frame 6 on the corresponding boss of groove; Can drag for 1 of valve shell 5 and urceolus, link 7 and 6 of supporting frames seal ring is housed respectively.
When this can drag for the work of valve formula oil well pump; When standing valve body cisco unity malfunction, can drag under the valve body and put into oil well pump, place the standing valve shell upper; Groove corresponding matching on link inner chamber middle part boss and the supporting frame replaces operations such as standing valve normally recovers the oil.Need oil pipe not proposed during maintenance, reduce operation cost, shorten the activity duration, reduce cost for oil production.
Claims (2)
1. one kind can be dragged for valve formula oil well pump; Comprise urceolus (1), standing valve (9); Standing valve (9) is seated on the standing valve seat (10); Standing valve (9) is equipped with standing valve shell (8) with standing valve seat (10) outside, and urceolus (1) is connected through link (7) with standing valve shell (8), it is characterized in that: described standing valve shell (8) top is connected with supporting frame (6); Supporting frame (6) upper end is equipped with can drag for valve seat (4); Can drag for valve seat (4) and go up sit to have and to drag for valve ball (3), can drag for valve seat (4) and be equipped with and to drag for valve shell (5), can drag for valve shell (5) top and be connected to fishing head (2) with dragging for valve ball (3) outside; Described supporting frame (6) bottom periphery has groove, link (7) inner chamber middle part have with supporting frame (6) on the corresponding boss of groove.
2. the valve formula oil well pump that drags for according to claim 1 is characterized in that: describedly drag between valve shell (5) and urceolus (1), seal ring be housed between link (7) and supporting frame (6) respectively.
