Background technique
In oil drilling construction, drilling mud pump is one of three-major-items equipment of oil drilling, and drilling pump is worked
Cheng Zhong, the upper water vat of drilling pump, the valve seat for draining cylinder are vulnerable parts, and valve seat is easily worn, and replacement is extremely frequent, chooses all
The tool that you sit be also it is varied, the most commonly used is it is a kind of it is inverted T shaped hang and take bar of choosing, although structure is simple, due to
Hang and take end be greater than valve sit interior diameter, need with seizing wire draw to hang and take end be less than valve sit interior diameter hang and take end ability
Into valve sit, due to hang and take end hang up valve sit after, state of the rope traction rope in cylinder can't see, during choosing
Easily haulage cable destruction is squeezed off, just can not normally make to hang and take end when reusing and hang over valve and take, in such case
Under, live common method is that valve seat puller is transferred to upper water chamber to make to hang and take end using the repeatedly method of percussion or undershoot
Valve is hung over to take or when taking and discharging end valve is sat, will manually hang and take end and hang over valve and take, it is very time-consuming and laborious,
There are also some potential safety problemss.It is just more time-consuming and laborious using manual method and percussion or undershoot if hanging and taking end deformation,
If it is serious to hang and take end deformation, just it is not available, needs replacing new bar of choosing, this method, both wasting manpower and material resources, increased
The labor intensity of post worker, reduces working efficiency, and increase drilling cost.
Summary of the invention
The purpose of the utility model is to provide a kind of drilling pump valves to sit puller, and it is all to solve drilling pump in the prior art
Your seat puller hangs and takes end haulage cable and damages, and hangs and takes end deformation and is difficult to hang, hangs and takes and hold deformation, operation is time-consuming and laborious, all
You, which sit, takes out difficult problem.
Above-mentioned purpose is achieved through the following technical solutions:
The utility model includes: center-pole, upper locking nut, jack, backing plate, lower locking nut, gasket, puller；
It is characterized in that: a kind of drilling mud pump valve sits the center-pole of pulling attachment, passed through from the center of puller, in puller
Top be cased with gasket, the top of gasket is equipped with lower locking nut, and lower locking nut is equipped with backing plate, and the top of backing plate is equipped with very heavy
The top on top, jack is equipped with upper locking nut.
A kind of above-mentioned drilling mud pump valve sits the center-pole top in pulling attachment equipped with square toes, and top is arranged with outer spiral shell
Line, lower part are equipped with nose cone.
A kind of above-mentioned drilling mud pump valve sits the jack in pulling attachment for hydraulic hollow jack, under jack
Portion is equipped with quick coupling.
It is rectangular slab that a kind of above-mentioned drilling mud pump valve, which sits the backing plate in pulling attachment, and centre is equipped with during diameter is greater than
The through-hole of core bar diameter.
A kind of above-mentioned drilling mud pump valve sits the puller in pulling attachment by lock sleeve, locking plate, elastic ring, lock tooth group
At；Locking plate be cylindrical shape, be made of four arc strip sheets, lower part be equipped with lock tooth, centre waled by elastic ring, locking plate it is upper
Portion is equipped with annular groove, and the annular groove of annular lock sleeve stuck lock piece blocks locking plate.
The beneficial effects of the utility model are: being suitable for oilfield drilling fluid pump maintenance, it can be realized and choose in valve seat
In the process, the locking plate of puller is sat the lock tooth of locking plate with valve and is contacted under the action of center-pole lower cone forming head, uniformly,
Reliably, the safe valve that blocks is sat, and under the action of hydraulic hollow jack, valve is sat and is extracted, is used manpower and material resources sparingly, improved
Working efficiency, guarantee have the oil drilling normally to produce.
