Abstract
The utility model relates to the technical field of drilling tools, in particular to an integral anti-drop bypass valve which comprises an anti-drop device, a bypass valve body, a valve core and a valve bushing; and the bypass valve body and the anti-drop device are in an integral structure. The utility model has the benefits that compared with the prior art, through the integral design of the bypass valve body and an anti-drop shell body, the integral anti-drop bypass valve not only overcomes the problems that the connecting thread has problems and is broken, the part below the broken part directly drops into a well and production accidents occur, improves the production safety factor, but also reduces the production cost, shortens the length of the anti-drop shell body, and saves raw materials.
Description
Technical field
The utility model relates to the boring tool technical field, particularly relates to the anti-lost bypass valve of a kind of integral type.
Background technology
At oil, geological drilling mechanical field, normally used helicoid hydraulic motor claims the fixed displacement motor again, is a kind of positive displacement mud motor.Because a series of characteristics of itself structure and aspect of performance are being widely used aspect oil drilling and the well workover, and be used to the operation of creeping into of aspects such as address matter exploration, coal-bed gas exploitation, building pipe construction and defence construction.Helicoid hydraulic motor is made up of bypass valve, single screw motor assembly, universal drive shaft assembly and driving-shaft assembly etc.Bypass valve is the accessory of helicoid hydraulic motor, and its effect is that space and ring control are linked up, and changes when single to avoid making a trip and to connect that drilling fluid overflows the pollution rig floor in the drill string, influences operate as normal.
The bypass valve valve body of original project organization and anti-lost housing are the split-type structural (see figure 2), and both are by being threaded, the fracture in case connecting thread goes wrong, and fracture causes production accident with the lower part well that will directly fall.
The utility model content
The purpose of this utility model is intended to overcome the deficiencies in the prior art, and provide a kind of integral type anti-lost bypass valve, not only overcome the connecting thread fracture that goes wrong, fracture is with the lower part well that will directly fall, cause the problem of production accident, improve the production safety coefficient, and reduced cost of production.
For realizing that the purpose of this utility model adopts following technical scheme: the anti-lost bypass valve of integral type is characterized in that it comprises: falling-proof apparatus, bypass valve valve body, spool and valve pocket; Described bypass valve valve body and falling-proof apparatus are structure as a whole.
Described falling-proof apparatus comprises anti-lost connecting rod, anti-lost nut, anti-lost housing, and wherein bypass valve valve body and anti-lost housing are structure as a whole.
Between described bypass valve valve body and spool, the valve pocket intermediate sleeve is set.
Add seal with elastometic washer between described intermediate sleeve and the valve interior wall.
The beneficial effects of the utility model are: compared with prior art, the utility model is by bypass valve valve body and the structurally design of integral type of anti-lost housing, not only overcome the connecting thread fracture that goes wrong, fracture is with the lower part well that will directly fall, cause the problem of production accident, improved the production safety coefficient, and reduced cost of production, shorten anti-lost shell length, saved raw material; In the middle of valve body and spool, the valve pocket intermediate sleeve is set, adds seal with elastometic washer between intermediate sleeve and the valve interior wall, make not exist relative motion, this structure design can make valve interior wall chromium plating more between the two, saved cost of production.
Description of drawings
The structural representation of the anti-lost bypass valve of integral type that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation that the anti-lost housing of existing techniques in realizing is connected with the bypass valve valve body.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Among the figure: 1. anti-lost connecting rod, 2. anti-lost nut, 3. anti-lost housing, 4. screw thread, 5. bypass valve valve body, 6. bypass valve valve pocket, 7. bypass valve spool, 9. intermediate sleeve, 10. seal with elastometic washer.
As shown in Figure 2, the anti-lost bypass valve of integral type is characterized in that, comprising: anti-lost connecting rod 1, anti-lost nut 2, anti-lost housing 3, bypass valve valve body 5, spool 7 and valve pocket 6; Bypass valve valve body 5 and anti-lost housing 3 as a whole structures.Between bypass valve valve body 5 and spool 7, the valve pocket 6 intermediate sleeve 9 is set.Add seal with elastometic washer 10 between intermediate sleeve 9 and the valve interior wall.
In sum, compared with prior art, the integral type that the utility model provides bleeds off bypass valve, by bypass valve valve body and the structurally design of integral type of falling-proof apparatus, not only overcome the connecting thread fracture that goes wrong, fracture is with the lower part well that will directly fall, cause the problem of production accident, improve the production safety coefficient, and shortened anti-lost shell length, saved raw material; Between bypass valve valve body 5 and spool 7, the valve pocket 6 intermediate sleeve 9 is set.Add seal with elastometic washer 10 between intermediate sleeve 9 and the valve interior wall.Make not have relative motion between the two, this structure design can make valve interior wall chromium plating operation again, thereby has saved cost of production.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (4)
