There is gate valve, upper pipe fitting threaded upper ends are sealedly connected with casing coupling, and casing coupling upper end internal screw thread is connected with closure, casing coupling
Upper end is provided with external member, and the external member includes two semicircle rings being hinged, and half is provided on two semicircle ring inner edges
Circular rubber ring, two semicircular ring outer rim are respectively and fixedly provided with the otic placode for closing up two semicircular ring, and two otic placodes pass through connection
It is bolted, the two semicircular ring banding is in casing coupling upper end.
Specifically, the blowout preventer ontology is flashboard type blowout preventer.
Specifically, being provided with stop valve for pressure gauge on the pressure pipe.
Compared with prior art, the utility model has the following beneficial effects:
1, the utility model, structure is simple, easy to operate, has and unloads oil pocket, can be timely on swab at the end of oil pumping
Oil be discharged to without being carried over ground in well, prevent pollution environment.
2, the rubber ring inside external member can wipe the crude oil of band on weighted lever off, and crude oil is avoided to leak outside.
3, blowout preventer is safe and reliable, and operating pressure is high, and unlatching, shutoff operation are convenient.
4, it is furnished with pressure gauge, it can pressure alteration situation in inspection well at any time.

Specific embodiment
As shown in Figure 1, well head environmental protection pumping means, including blowout preventer ontology 5, the blowout preventer ontology 5 are flashboard type envelope
Well device, thread seal is connected with upper pipe fitting 4 and lower pipe fitting respectively on the liquid outlet and inlet of 5 top and bottom of blowout preventer ontology
12, it is respectively formed inside upper pipe fitting 4 and lower pipe fitting 12 and unloads oil pocket, the internal diameter of upper pipe fitting 4 and lower pipe fitting 12 is all larger than the diameter of swab,
12 lower end of lower pipe fitting is fixed with connecting flange 6, is fixed in lower pipe fitting 12 and its internal pressure pipe 13 being connected to, 13 end of pressure pipe
End is equipped with pressure gauge 8, is provided with stop valve for pressure gauge 7 on the pressure pipe 13.Be fixed in upper pipe fitting 4 communicate therewith go out
Oil pipe 9 is provided with gate valve 10 on flowline 9, and 4 threaded upper ends of upper pipe fitting are sealedly connected with casing coupling 3,3 upper end of casing coupling
Internal screw thread is connected with closure 2, and 3 upper end of casing coupling is provided with external member 1, and the external member 1 includes two semicircle rings being hinged
14, the rubber ring 15 of semi-annular shape is provided on two 14 inner edges of semicircle ring, 14 outer rim of two semicircular ring is respectively and fixedly provided with use
In the otic placode 16 for closing up two semicircular ring 14, two otic placodes 16 are bolted by connection, and 14 banding of two semicircular ring is covering
3 upper end of pipe box cupling.
When the utility model is installed, connecting flange 6 and well head four-way flange are bolted to connection, usually shunt in a well
When, blowout preventer ontology 5 is closed, 9 gate valve 10 of flowline is in close state, and is blocked 2 and is tightened, and stop valve for pressure gauge 10 is opened, and is led to
