Two preventers are annular preventer or single ram type perventer or double ram type preventer.
The invention also discloses a kind of preventer group tooling for realizing preventer group assembly method as described above, the works
Dress is heavy wall guide pipe, and the heavy wall guide pipe is placed in the passing hole of the first preventer, the heavy wall guide pipe and described the
The passing hole of one preventer matches, several cross bars for slinging the second preventer are provided in the heavy wall guide pipe,
The passing hole of second preventer is directed at the heavy wall guide pipe on first preventer, on second preventer
Gasket annular groove and the metal sealing cushion ring on first preventer are to being just bonded.
Preferably, the gap between the heavy wall guide pipe and the passing hole of first preventer is 0.5-1mm.
Preferably, several described cross bars intersect setting respectively.
Preferably, first preventer is annular preventer or single ram type perventer or double ram type preventer；Described
Two preventers are annular preventer or single ram type perventer or double ram type preventer.
Compared with prior art, the invention has the benefit that heavy wall guide pipe of the invention can be effectively protected it is anti-
Gasket annular groove, gasket ring on spray apparatus, it is easy to use to lean on, production efficiency is improved, the gasket on preventer is reduced
The damage of annular groove and gasket, reduces costs.

Specific embodiment
In order to keep the present invention more obvious and easy to understand, the present invention is done furtherly below in conjunction with the drawings and specific embodiments
It is bright.
As shown in Fig. 1-Fig. 3 combination, preventer group of the invention includes ring-like preventer, double ram type preventer and single disc
Preventer.As shown in Fig. 4 and Fig. 5 combination, the present invention devises a kind of heavy wall guide pipe 3, which, which is equipped with, adds
Big chamfering, such as 40 × 45 °.Heavy wall guide pipe 3 is internally provided with several cross bars 301 to intersect vertically, for lifting by crane.
As shown in fig. 6, the preventer group assembly method for protecting metal sealing cushion ring of the invention specifically:
When installing preventer group, metal sealing cushion ring 4 is first mounted on the first preventer (such as single ram type perventer
2) on, the heavy wall guide pipe 3 made is put into the passing hole of the first preventer, it is anti-then to sling second by cross bar 301
The passing hole of second preventer is directed at the heavy wall guide pipe 3 on the first preventer, then fallen by spray apparatus (such as annular preventer 1)
Lower second preventer, makes heavy wall guide pipe 3 pass through the passing hole of the second preventer, continues to fall, make close on the second preventer
Packing annular groove accurately with the metal sealing cushion ring 4 on the first preventer to just, be bonded, effectively prevent damaging gasket ring groove face by pressure
