Abstract
The utility model relates to one and pulls out valve group tool, comprises U-shaped positioning head, pedestal, leading screw, fixed head and nut, and wherein, U-shaped positioning head is laterally fixedly connected on pedestal, pedestal in the top of U-shaped positioning head and bottom respectively to extension generate step; One end of leading screw is flexibly connected with two sidewalls of U-shaped positioning head by pin, and other end attaching nut, leading screw is set with fixed head.Valve body can be separated by simple structure by the utility model very smoothly from the water injecting pump pump housing, decreases the damage because hard power effect causes valve body; Meanwhile, save manpower, the valve body taken out can also reuse, and greatly reduces production cost.
Description
Technical field
The utility model belongs to field of petroleum machinery, and particularly one pulls out valve group tool.
Background technology
In oilfield development process, by water injecting pump, water is injected underground, keep or recover formation pressure, making oil reservoir have stronger driving force, to improve exploitation rate and the recovery ratio of oil reservoir.Water injecting pump carrys out guaranteed flow by valve body, but is through long-time use, and the valve body of water injecting pump often weares and teares and gets rusty, and when taking off valve body, workman often uses the hard power methods such as tup impact, causes very large damage to valve body.Therefore, need to design a kind of device that can take off valve body smoothly, reduce the damage that hard power causes valve body.
Summary of the invention
The utility model provides one and pulls out valve group tool, solve in the past workman by hard power by valve body from the water injecting pump pump housing separation difficulty, the problems such as damage are caused to valve body.
The utility model is achieved through the following technical solutions: one pulls out valve group tool, comprise U-shaped positioning head, pedestal, leading screw, fixed head and nut, wherein, U-shaped positioning head is laterally fixedly connected on pedestal, pedestal in the top of U-shaped positioning head and bottom respectively to extension generate step; One end of leading screw is flexibly connected with two sidewalls of U-shaped positioning head by pin, and other end attaching nut, leading screw is set with fixed head.
Further, the openend of described U-shaped positioning head is inclined plane.
Adopt the good effect of technique scheme: valve body can be separated by simple structure by the utility model very smoothly from the water injecting pump pump housing, decreases the damage because hard power effect causes valve body; Meanwhile, save manpower, the valve body taken out can also reuse, and greatly reduces production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
State diagram when Fig. 2 is the utility model practical application.
In figure, 1 U-shaped positioning head, 2 pedestals, 3 leading screws, 4 fixed heads, 5 nuts, 6 valve bodies.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is structural representation of the present utility model, as shown in the figure, one pulls out valve group tool, comprise U-shaped positioning head 1, pedestal 2, leading screw 3, fixed head 4 and nut 5, wherein, U-shaped positioning head is laterally fixedly connected on pedestal, and pedestal, is convenient to block valve body to be removed respectively to extension generate step in the top of U-shaped positioning head and bottom.One end of leading screw is flexibly connected with two sidewalls of U-shaped positioning head by pin, other end attaching nut, ensures that leading screw one end can be rotated along pin, leading screw is set with fixed head, the effect of fixed head keeps off outside the pump housing, and when ensureing that nut rotates, valve body 6 proposes by guide screw movement.
Further, in order to prevent the edge of U-shaped positioning head from scratching valve body, and do not cause the damage to valve body, and make U-shaped positioning head enter valve inner by the hole of valve body central authorities smoothly, the openend of described U-shaped positioning head is inclined plane.
State diagram when Fig. 2 is the utility model practical application, concrete, U-shaped positioning head is due to one end open, therefore be that light one end, one end is heavy, therefore, U-shaped positioning head is generally the state being in inclination, when extending into valve body 6 from the hole of valve body 6 central authorities and being inner, now, leading screw can drive U-shaped positioning head and base to reach body base always, carries leading screw then, valve body is just stuck on the position of the step of pedestal, now, U-shaped positioning head will no longer tilt, and pedestal and valve body keep agreeing with.By fixed head gear outside the pump housing, the nut of rotating threaded shaft one end, under the effect of screw thread, leading screw setting in motion, thus utilize U-shaped positioning head and pedestal to be taken out of by valve body, until valve body and the water injecting pump pump housing are separated completely.This process reduces to minimum by the damage of valve body, ensures that valve body can also reuse.
Valve body can be separated by simple structure by the utility model smoothly from the water injecting pump pump housing, and decreases because hard power effect is to the damage of valve body; The utility model is easy-to-understand, easy and simple to handle, saves manpower; Save in the past in the time of taking off valve body, the valve body taken out can also reuse, and greatly reduces production cost.
