STANDING VALVE.

Application filed October 12, 1926. Serial No. 141,172.

In wells having a great deal of sand mixed with the oil, it frequently occurs that the standing valve becomes sanded up; that is, the sand deposits and packs so tightly in the valve that it ceases to function and the pump thereupon becomes inoperative. This requires that the pumping equipment he removed from the well which is costly and requires considerable time, during which the well is idle. 7

An object of my invention is to provide a standing valve in which is minimized the danger of sanding up.

Another object is to provide an attachment for standing valves which will in large measure obviate the danger of sanding up. f V

A further object is to provide an improved standing valve of the character stated which is simple in construction and effective in operation.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined, detailed description or the appended claim.

In the drawing Fig. 1 is a longitudinal, sectional view of a standing valve embodying my invention.

Fig. 2 is a longitudinal, sectional view of the standing valve liner.

Fig. 3 is a side elevation of a modified form of liner;

Fig. 4 is a longitudinal, sectional view of an improved standing valve.

Referring more particularly to the drawing:

The usual standing valve 1 has a ball seat 2 screwed therein, and an apron 3 threaded onto the lower end of said seat, said apron being seated in the lower end of the pump as will be apparent to those skilled in the art. Other coupling means and ball seats may also be used without departing from the spirit of my invention.

I have discovered that by increasing the velocity of the fluid through the standing valve, that there is less likelihood of the sand settling and packing in the valve thereby rendering it inoperative. I provide this increased fluid velocity by a constricted passage extending to the lower end of the standmg valve. This constricted passage may be provided by means of a sleeve 4: which screws into the apron 3 and the upper end thereof terminating adjacent the ball check 5.

The sleeve 4 is provided with a conical passage 6, said passage tapering to a constricted opening at the top of the sleeve as will be apparent from Fig. 2. Thus during the operation of the pump the fluid in passing upwardly through the standing valve 1 has its velocity increased and carries the sand upwardly away from the standing valve; thus enabling said valve to operate. properly at all times.

IV hen a gas anchor is used I pr'ovide a sleeve 7 mounted in the same manner as above stated, but the lower end thereof is extended downwardly and threaded so as to accommodate the gas anchor or the like. The same results as above stated may also be obtained in the manner shown in Fig. 4, namely a conical passage 9 may be formed in the lower part of the standing valve 1, said passage extending to the ball seat 10; this passage may be integral with the standing valve or it may be formed in the apron 11 and sleeve 12, thatis, the apron and sleeve may be bored to provide the tape-red passage 9 when assembled on the. standing valve. It is obvious that other similar ar angements may also be employed to provide a conical passage extending to the ball seat in the standing valve.

Having described my invention, I claim:

In a standing valve cage including a ball and seat therefor, anapron depending from said cage and secured thereto, a valve liner attachment comprising a sleeve, threads on said sleeve adapted to screw into said apron, said sleeve terminating below the seat and having a conical bore extending therethrough.

In testimony, whereof, I affix my signature.
