Abstract

The utility model relates to the field of the pipe joint with the screwed joint. The lock unit for pipe thread connection of pump of this design is composed of a pipe jointer (2) which are connected with two pump pipes (1) by screws and two anti-falling antiskid buttons (3) which are pressed firmly on the two ends of the pipe jointer (2) and are connected with the pump pipes (1) by screws. Another scheme is that the utility model is composed of a pipe jointer (4) welded on a pump pipe (6) and an anti-falling antiskid button which is pressed firmly on one end of the pipe jointer (4) and is connected with another pump pipe (1) by a screw. Because the anti-falling antiskid button is pressed firmly on the pipe jointer, the nut of the pipe jointer and the screw of the pump pipe can be combined tightly. Consequently, in the using process of the deep-well pump, the silk falling, the silk sliding and the stripping caused by shock and swing can be effectively prevented.

Description

Lock unit for pipe thread connection of pump

The utility model relates to the pipe joint field of inipple.At present, used pump line is all connected by conventional pump pipe joint Pipe jointer on deep-well pump.For example all to use length be that 110 millimeters Pipe jointer is threaded to 20 and 30 meters deep-well pump pump line, because the vibrations of deep-well pump and swing often make this screw thread Pipe jointer wire inversion, stripped thread even cause and take off pipe, thereby delays or interrupts drawing water of pump, very inconvenient.

The purpose of this utility model provides and a kind ofly can make anti-down, the anti-skidding pump line of the Pipe jointer locker that is threaded.

The purpose of this utility model reaches like this: adopt the pump line of being made up of the anti-skid button that is threadedly connected to the Pipe jointer on the pump line and press from these Pipe jointer one or both ends locker that is threaded, the purpose of the design's locker has just reached fully.

Below in conjunction with accompanying drawing the utility model locker is elaborated:

Accompanying drawing 1 is the plan view and the longitudinal section of conventional pump pipe thread connector; Accompanying drawing 2 is two pump line be threaded plan view and longitudinal sections of locker buckled; Accompanying drawing 3 is single pump line be threaded plan view and longitudinal sections of locker buckled; Accompanying drawing 4 is that two nuts of buckleing the Pipe jointer of locker are pressed and the close schematic representation that is connected by the anti-skid fastening with the pump line screw thread.

Accompanying drawing 1 is the effective screw thread Pipe jointer of conventional pump, and Pipe jointer (7) is threaded respectively with the pump line (1) at two ends, and for the pump line of 20 or 30 meters lifting pumps, this Pipe jointer (7) length is 110 millimeters, and internal diameter is the 114+2 millimeter.When this Pipe jointer is used on the deep-well pump line, because the vibrations of pump and swing and wire inversion or stripped thread even take off pipe.

Accompanying drawing 2 is two pump line lockers that are threaded of buckleing, by being threadedly connected to the Pipe jointer (2) on two pump lines (1) and pressing in Pipe jointer (2) two ends and two the anti-skid buttons (3) that are threadedly connected on the pump line (1) are formed, screw thread, the nut of pump line (1) and Pipe jointer (2) and anti-skid button (3) all is same size and can arranges in pairs or groups mutually.At lift is that used Pipe jointer (2) is 60 millimeters long on 20 or 30 meters deep-well pump pump lines, and diameter is the 114+2 millimeter, and the diameter of anti-skid button (3) is identical with the diameter of Pipe jointer (2), and length is 25 millimeters.Like this, the length of three pipe fittings is added up and is equaled the length of common Pipe jointer, but the anti-skid that is threaded of the design's locker can force rate strong many of prior art Pipe jointer, from the vibrations and the swing of deep-well pump.

The be threaded using method of locker of two button pump lines is as follows: screw in the anti-skid button respectively earlier on the screw thread of two pump lines (1), use Pipe jointer (2) that two pump lines (1) are threaded again, subsequently, respectively with two anti-skid button reversings, make respectively and press to Pipe jointer (2), thereby the nut of Pipe jointer and the screw thread of pump line (1) are combined closely, therefore play the effect of anti-skid.

Another program of the design's locker is seen accompanying drawing 3, and this single button pump line locker that is threaded is formed with the anti-skid button (5) that is pressed on said Pipe jointer (4) one ends and be threadedly connected on another root pump line (1) by being welded in the Pipe jointer (4) that a pump line (6) goes up and be threadedly connected on another root pump line (1).The be threaded using method of locker of single button pump line is as follows: earlier Pipe jointer (4) is welded on the pump line (6), also can use the pump line (6) that welds in batch and the single piece of Pipe jointer, then, anti-skid button (5) is spun on the pump line (1), to screw in the pump line (1) of this anti-skid button (5) among the above-mentioned Pipe jointer again, then, make anti-skid button (5) reversing, make it be pressed on an end of Pipe jointer, thereby play the effect of anti-skid and anticreep pipe.The size of Pipe jointer (4) and anti-skid button is identical with two button persons.

From accompanying drawing 4 as seen, be example with two button lockers, the screw thread of the nut of Pipe jointer (2) and pump line (1) is at vertically be stressed (shown in arrow), thereby makes the tightr of their combinations, is difficult for loosening and slippage.

The utility model is threaded locker when being used for the pump line threaded joints, because the anti-skid button presses Pipe jointer from both ends or one end, combine closely thereby make between Pipe jointer nut and the pump line screw thread, thereby in the deep-well pump using process, can prevent effectively because the wire inversion that vibrations and swing caused, the stripped thread of pump and take off pipe make deep-well pump can be in good working order for a long time.

Claims

1, the pump line locker that is threaded is characterized in that: be made up of each the anti-skid button that is threadedly connected on the pump line (1) that is threadedly connected to the Pipe jointer (2) on two pump lines (1) and is pressed on said Pipe jointer (2) two ends.
