Description
Technical field
The utility model is related to pressure break pump technical fields, more particularly to fracturing pump drawing valve seat tool.
Background technology
Fracturing pump is the important equipment in pressure break Completion Operations, and the mixing of fracturing fluid and proppant can be provided for underground
Liquid and high voltage power form common conveying oil circuit so as to achieve the purpose that press off, dredge stratum.Valve body and valve seat are
Important vulnerable part, needs to be replaced frequently in fracturing pump, and valve seat replaces efficiency due to being that interference is packed into replacement difficulty in clack box
Low, basic reason is the absence of special extracting tool, and common tool generally use hammers, the method for top pressure, be easy to cause
Damage to fracturing pump and other component；Also have and extract the work of valve seat equipped with irregular moving block using in the bottom of pull rod
Tool, but since moving block is irregular, rotation is not easy to control, dismounting valve seat is time-consuming, laborious, influences fracturing pump normal operation.
Utility model content
To overcome the deficiencies of existing technologies, the utility model provides a kind of fracturing pump drawing valve seat tool, and rapid and convenient is more
Pressure break pump valve seat is changed, simple and reliable, time saving and energy saving, the efficiency of valve seat is replaced at the scene of raising, improves field operation efficiency, reduces pressure
Split the risk of pump damage.
The technical scheme adopted by the utility model is that：A kind of fracturing pump drawing valve seat tool, including screw rod 10, back tightening nut
20 and hydraulic cylinder 30, the hydraulic cylinder 30 is placed in 40 upper surface of clack box, and is equipped with oil inlet 31, and the back tightening nut 20 passes through spiral shell
Bar 10 will be carried on the back between hydraulic cylinder 30, clack box 40 and plug 70 it is tight, the screw rod 10 by hydraulic cylinder internal holes penetrate plug 70 and
Valve seat 50, the plug 70 are opposite opened structure, and split face lower part is equipped with inclined-plane, and angle is formed in two halves plug lower part, internal
Equipped with screw thread, outside is connected using clip 60.
Above-mentioned technical proposal can advanced optimize for：
Hanging ring 80 is installed on the clip 60, suspension chain 90 is connected on hanging ring 80.
The 10 entire body thread button of screw rod, 10 both ends of screw rod are equipped with the aperture perpendicular to axis, backing pin are installed in aperture.
Assister bar 21 there are three being set on the back tightening nut 20.
Fracturing pump drawing valve seat tool provided by the utility model passes through hydraulic cylinder 30,10 and of screw rod using hydraulic pressure as power
70 passing power of plug, quickly and easily drawing, replacement pressure break pump valve seat 50, simple and reliable, and time saving and energy saving, the scene of raising is replaced
The efficiency of valve seat 50 improves field operation efficiency, reduces the risk of fracturing pump damage.

Specific implementation mode
Referring to Fig.1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of fracturing pump drawing valve seat tool, including screw rod 10, back tightening nut 20
With hydraulic cylinder 30, the hydraulic cylinder 30 is placed in 40 upper surface of clack box, and is equipped with oil inlet 31, and the back tightening nut 20 passes through screw rod
10 will carry on the back tightly between hydraulic cylinder 30, clack box 40 and plug 70, and the screw rod 10 penetrates plug 70 and valve by hydraulic cylinder internal holes
Seat 50, the plug 70 are opposite opened structure, and split face lower part is equipped with inclined-plane, form angle in two halves plug lower part, inside is set
There are screw thread, outside to be connected using clip 60, when in use, is first adjusted to enter valve seat orifice state by plug 70, waits for 70 bottom of plug
When the outer circle step in portion is moved down more than 50 lower face of valve seat, screw rod 10 is installed in plug 70, plug 70 is strutted into valve
State after bore, at this time the outer circle step upper surface of 70 bottom of plug be in contact with 50 lower face of valve seat；Hydraulic cylinder 30 is passed through
Screw rod 10 is positioned over 40 upper surface of clack box, tightens back tightening nut 20, and clack box 40, plug 70,30 three of hydraulic cylinder are mutually carried on the back
Tightly, then by external hand hydraulic pump, from oil inlet 31 to hydraulic cylinder 30 inside be filled with highly pressurised liquid, until valve seat 50 drawn
It pulls out and enters relaxed state.
In a preferred embodiment, hanging ring 80 is installed on the clip 60, suspension chain 90 is connected on hanging ring 80,
Plug 70 is held by hanging chain 90, hanging ring 80 and clip 60 during use, prevents plug from falling into 40 pump chamber of clack box；Peace
Suspension chain 90 is put into inside clack box after dress.
The 10 entire body thread button of screw rod, 10 both ends of screw rod are equipped with the aperture perpendicular to axis, backing pin are installed in aperture,
It is suitable for the drawing with the valve seat 50 of different model pressure break pump hydraulic end, and prevents back tightening nut 20 from exiting.
Assister bar 21 there are three being set on the back tightening nut 20, tightens back tightening nut 20 by assister bar 21, more saves
Power.
