Description
Technical field
Originally it is new to be related to oil field equipment technical field, belong to a kind of oil pumper fast-assembling magnetic control blowout prevention box.
Background technology
The moment there is alternate load, often occurs light rod-broken and causes environmental pollution feelings oil pumper in process of production
Condition.Processing environment pollution is costly.Need to shut down after kill-job to be installed during the blowout prevention box installation used now, due to cost
High, installation is inconvenient to prevent rod-pumped well blowout prevention box from popularizing, and bar, which is had no progeny, causes large area environmental pollution, using the side of anti-lost card
Method easily causes the disconnected environmental pollution of bar on the contrary sometimes.
Utility model content：
In order to solve technical problem present in background technology, the utility model proposes a kind of oil pumper fast-assembling magnetic control blowout prevention
Box, the utility model when light rod-broken can timely blowout prevention, greatly reduce environmental pollution.
The technical solution of the utility model is：A kind of oil pumper fast-assembling magnetic control blowout prevention box, the blowout prevention box include blowout prevention box master
Body, spring is installed in blowout prevention box body top tubular cavity body, the side of spring is provided with magnetic block, magnetic block and trigger shaft
One end connection, the other end of trigger shaft extended to outside blowout prevention box main body through the cavity wall of tubular cavity body, the end of trigger shaft
Corresponding with firing device, the lower surface of firing device is fixedly connected with connecting rod and connecting rod is hinged with blowout prevention box main body, blowout prevention box master
Body middle part of sliding channel, which is extended, is provided with spray-proof ball in cylindrical cavities and cylindrical cavities, spray-proof ball side is provided with push rod, push rod
The other end extended to through cylindrical cavities wall outside blowout prevention box main body.
The utility model has the advantages that：First, blowout prevention is promptly and accurately：When conventional bar breaks, because spray-proof ball is in pipe
In post by polished rod abrasion and greasy filth it is viscous, it is impossible to ejection in time, thus blowout prevention effect is poor, environmental pollution is larger.This
New spray-proof ball does not contact with polished rod, and its internal greasy dirt can be removed in time in the case of non-stop-machine, so its blowout prevention
Effect is preferable, so as to greatly reduce environmental pollution；Second, shortening the installation operation time, operating efficiency is improved：Installation in the past
Needed during blowout prevention box carry out hot wash kill-job, change a bite well packing box need 2 hours, yield recover need 8 hours with
On.10 minutes or so are needed using this new latter quick and easy for installation, it is not necessary to carry out hot wash kill-job.Every mouthful of well reduces operation
110 minutes or so time, reduce production loss caused by kill-job.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
In figure：(1)-spring, (2)-magnetic block, (3)-trigger shaft, (4)-firing device, (5)-push rod, (6) Gu-
Determine screw, (7)-sealed screw, (8)-spray-proof ball, (9)-blowout prevention box main body.
Embodiment：
With reference to example, the utility model is described in further detail：
Oil pumper fast-assembling magnetic control blowout prevention box is Split type structure, and polished rod passes through from blowout prevention box center, and the blowout prevention box includes blowout prevention
Box main body 9, spring 1 is installed in the top tubular cavity body of blowout prevention box main body 9, the side of spring 1 is provided with magnetic block 2, Qiang Ci
Block 2 is connected with one end of trigger shaft 3, and magnetic block 2 and polished rod are attracting, and magnetic block 2 loses suction, magnetic block 2 after light rod-broken
It is moved rearwards together with trigger shaft 3 under the elastic force effect of spring 1, the other end of trigger shaft 3 prolongs through the cavity wall of tubular cavity body
Extend outside blowout prevention box main body 9, the end of trigger shaft 3 is corresponding with firing device 4, and the lower surface of firing device 4 is fixedly connected with connecting rod
And connecting rod is be hinged with blowout prevention box main body 9, the middle part of sliding channel of blowout prevention box main body 9, which is extended in cylindrical cavities and cylindrical cavities, to be installed
There is spray-proof ball 8, the side of spray-proof ball 8 is provided with push rod 5, and the other end of push rod 5 extends to blowout prevention box main body 9 through cylindrical cavities wall
Outside.Magnetic block 2 together with being moved after trigger shaft 3 during firing device 4 can be promoted to impact push rod 5 after moving downward, push rod 5 is to reach
It is dynamic to promote spray-proof ball 8, promote spray-proof ball 8 to leave cylindrical cavities and the mesh that polished rod passage reaches sealing is closed under the promotion of liquid
's.
Sealing gasket is placed on to the joint of the blowout prevention box of split during installation, blowout prevention box main body sealed screw 7 is fixed
It is placed on packing box, tightens bottom fixation jackscrew 6 and blowout prevention box is fixed on packing box.During normal production, oil pumper magnetic control is prevented
The magnetic switch that spray apparatus is made up of spring, Qiang Ci, trigger shaft, firing device etc., when polished rod occurs disconnected de-, magnetic switch loses suction,
Rear portion firing device, which falls, impacts push rod by quick blowout prevention in spray-proof ball push-in blowout prevention box.
