Abstract
The utility model discloses an anti-falling assembly for a standing valve of an oil-well pump, which comprises a valve body, a valve cover, a ball sealer and a valve ball seat and is characterized in that in the valve body which is set to be cylindrical, the outer periphery of the upper part is provided with oil-pipe male threads, the inner periphery of the upper part is provided with button-head female threads, the lower part is provided with oil-pipe female threads, and the inner periphery of the middle lower part is provided with an annular boss; the annular boss is provided with spare button-head female threads; the valve ball seat is arranged on the annular boss in a sitting way; the ball sealer is placed on the valve ball seat and is covered with the valve cover provided with an oil introduction hole; and the valve cover is in threaded connection with the valve body, the upper part of the valve body is connected with the lower end of a pump cylinder, and the lower part of the valve body is connected with a tail pipe. By means of the anti-falling assembly provided by the utility model, the tail pipe is prevented from falling, the fill factor of the pump cylinder is increased and the pump efficiency is improved.
Description
Technical field
The utility model relates to a kind of oil well pump standing valve anticreep assembly, and the ball cover that solves existing standing valve assembly bears the valve ball that the heavy duty of tail pipe causes, ball cover and tail pipe one well that rises and falls causes the problem of serious accident.
Background technique
At present, standing valve ball cover on the tubing pump that the oil field is used plays double action, not only held out against the valve ball seat but also connected tail pipe under the pump, thread is flat button, and tensile strength is low, meeting vibrations gets loose easily, cause fixed valve base top not tightly, cause leakage, the time has been grown easily in addition and tail pipe falls in the well together, cause workover, cause bigger economic loss to the oil field.
Summary of the invention
The purpose of this utility model provides a kind of oil well pump standing valve anticreep assembly, overcomes the problem that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of valve body, valve bonnet, ball sealer and valve ball seat, it is cylindrical to it is characterized in that valve body is made as, upper periphery is provided with the oil pipe male thread, be provided with flat button box thread interior week, the bottom is provided with the oil pipe box thread, and week is provided with annular boss in the middle and lower part, annular boss is provided with standby flat button box thread, sitting on annular boss has the valve ball seat, is placed with ball sealer on the valve ball seat, is covered with the valve bonnet that has oil through on the ball sealer; Valve bonnet is threaded with valve body, and the top of valve body is connected with the pump barrel lower end, and the bottom of valve body is connected with tail pipe.
The utility model is located at the top of ball sealer with valve bonnet, can allow ball sealer in time reset, and has improved the filling index and the pump efficiency of pump barrel, and tail pipe is threaded with the direct-connected adapter of valve body, is connected firmly, and has prevented the serious accident that tail pipe comes off and causes.
The utility model is the valve bonnet design that the ball sealer diameter is 3 times of valve seat conical surface lower diameter on the top of ball sealer rather than the guiding theory of bottom, this is usually the standard of design, the serious again seat that is to say the ball sealer corrosion can not fall into the shaft bottom yet, in addition frequent at ordinary times measuring indicator diagram, examine the pump maintenance once finding the standing valve leakage, it is impossible that ball sealer falls into the shaft bottom, the valve bonnet design is on the top of ball sealer, define ball sealer and rise height, can in time reset, prevented that the crude oil that enters pump barrel from flowing backwards, and can significantly improve the filling index and the pump efficiency of pump barrel.

Embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description: the utility model is made up of valve body 1, valve bonnet 2, ball sealer 3 and valve ball 4, it is cylindrical to it is characterized in that valve body 1 is made as, upper periphery is provided with the oil pipe male thread, be provided with flat button box thread interior week, the bottom is provided with the oil pipe box thread, week is provided with annular boss in the middle and lower part, annular boss is provided with standby flat button box thread, on annular boss, sit valve ball seat 4 is arranged, be placed with ball sealer 3 on the valve ball seat, be covered with the valve bonnet 2 that has oil through on the ball sealer; Valve bonnet is threaded with valve body, and the top of valve body is connected with the pump barrel lower end, and the bottom of valve body is connected with tail pipe.
When using the utility model, it is lowered to the designed degree of depth of oil well with tubing string, again pump plunger is lowered to pump barrel with the sucker rod roofbolt, when pump plunger is up, ball sealer 3 is smoked, crude oil enters pump barrel through tail pipe, ball sealer can in time reset under the effect of valve bonnet 2 when pump plunger is descending, and the crude oil that can not enter pump barrel flows backwards, thereby has improved the filling index and the oil well pump pump efficiency of pump barrel, if be afraid of that ball sealer falls into the shaft bottom, can a valve bonnet be installed on the annular boss box thread of valve body, this valve bonnet is not connected with tail pipe, and tail pipe is connected with valve body, be connected firmly, the tail pipe obscission can not take place.
