Description
Technical field
The utility model is related to helicoid hydraulic motor technical field more particularly to a kind of helicoid hydraulic motor integrated anti-uncouplings of rear-loading type
Head.
Background technology
Currently, the security system used in the drilling engineering of petroleum gas, it is with anti-boom, anti-cap off, anti-lost connects
Head forms anti-lost assembly, anti-lost assembly top connecting bypass valve assembly.When lower part is broken, rotor, anti-boom and anti-lost
Cap moves down, and anti-cap off is pressed on the through-hole of anti-lost connector, and mud is prevented to enter, and pump pressure increases, and gives ground personnel's early warning, closes mud
Stock pump, above carries screw rod, and anti-falling stop well accident occurs.But existing anti-lost assembly can only prevent assembly with lower part, if bypass
Valve be broken, anti-lost assembly cannot play the role of it is anti-lost, and by-passing valve be broken, cause spool valve pocket to fall off, fall into shaft bottom, into one
Step increases the salvaging difficulty of screw rod, causes the salvaging period elongated, serious waste of resources, work efficiency drop.
Utility model content
Purpose of the utility model is to overcome the shortcomings of the above technology, and to provide a kind of helicoid hydraulic motor rear-loading type one
Retaining connector.
The utility model to achieve the above object, using following technical scheme：
A kind of helicoid hydraulic motor rear-loading type one retaining connector, it is characterised in that：Including the anti-lost ontology of one, positioning spiral shell
Nail, clamp spring, sieve plate, it is anti-cap off, anti-lost pad, anti-boom, stator, rotor, locating ring, pin, spool, spring, valve pocket and close
Seal；The spool is mounted in the valve pocket, and for the spring pocket between the spool and valve pocket, valve pocket passes through the positioning
Screw is fixed with the anti-lost ontology of the one, and the locating ring is fixed together by the pin and the valve pocket, spool
Top is locked to the lower section of locating ring, and the sieve plate is fixed in the sieve pore on the anti-lost ontology of one by the clamp spring, described fixed
The sub lower part with the anti-lost ontology of the one links together, and the rotor, which is fixed together and is mounted on the anti-boom, to be determined
It is sub internal, it is described to prevent capping off through the anti-lost pad mounted on the top of the anti-boom.
Preferably, the sealing ring is mounted between the spool and the valve pocket.
The utility model has the beneficial effects that:Compared with the existing technology, the utility model is simple in structure, easy to process, group
Dress, member replacing is convenient, service life is long.Rear-loading type one retaining connector solve screw rod cannot whole anticreep the drawbacks of,
It solves and falls well accident caused by by-passing valve pin thread is broken；Also bypass valve core and valve pocket caused by falling well are solved and deviates from this
Body increases and salvages difficulty, increases the problem of salvaging the period.Rear-loading type one retaining connector strengthens the intensity of screw body, peace
Full property greatly reinforces；Again because reducing procedure of processing, saves production cost, shortens the production cycle；Again because being whole
Anticreep avoids and falls well accident caused by by-passing valve is broken, and is avoided for drilling team and salvages the time, eliminates unnecessary resource
With the waste of manpower.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment of the present utility model is described in detail in preferred embodiment.
In the description of the present invention, it should be understood that term "center", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of description of the present invention and simplification of the description, and does not indicate or imply the indicated dress
It sets or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to the utility model
Limitation.
As shown in Figure 1, a kind of helicoid hydraulic motor rear-loading type one retaining connector, including the anti-lost ontology 1 of one, positioning screw
2, clamp spring 3, sieve plate 4, anti-cap off 5, anti-lost pad 6, anti-boom 7, stator 8, rotor 9, locating ring 10, pin 11, spool 12, spring
13, valve pocket 14 and sealing ring；The spool be mounted on the valve pocket in, the spring pocket between the spool and valve pocket,
Valve pocket is fixed by the positioning screw and the anti-lost ontology of the one, and the locating ring is solid by the pin and the valve pocket
It is scheduled on together, the top of spool is locked to the lower section of locating ring, and the sieve plate is fixed on the anti-lost ontology of one by the clamp spring
Sieve pore in, the lower part of the stator and the anti-lost ontology of the one links together, and the rotor is fixed with the anti-boom
Together and it is mounted on stator interior, it is described to prevent capping off through the anti-lost pad mounted on the top of the anti-boom.It is described close
Seal is mounted between the spool and the valve pocket.
The utility model is simple in structure, and easy to process, assembling, member replacing is convenient, service life is long.Rear-loading type is integrally anti-
Uncoupling head solve screw rod cannot whole anticreep the drawbacks of, also solve and fall well accident caused by by-passing valve pin thread is broken；
It solves the problem of that bypass valve core and valve pocket abjection ontology increase caused by falling well salvage difficulty, increase and salvage the period.Rear-loading type
Integrated retaining connector strengthens the intensity of screw body, and safety greatly reinforces；Again because reducing procedure of processing, life is saved
Production cost shortens the production cycle；It again because being whole anticreep, avoids and falls well accident caused by by-passing valve is broken, be well
The waste that team avoids and salvages the time, eliminates unnecessary resource and manpower.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
