Abstract
The utility model discloses a hinge for a blowout preventer, comprising an upper hinge seat (2), a lower hinge seat (3), and a side door (4). The side door (4) is arranged between the upper hinge seat (2) and the lower hinge seat (3). The hinge is characterized in that a flow guide tube (1) is also arranged inside the upper hinge seat (2); one end of the flow guide tube (1) is connected with the upper hinge seat (2), while the other end is connected with the side door (4). An internal conduit structure is adopted in the hinge. The arrangement of an opening oil passage and a closing oil passages is skillfully achieved so that the opening oil passage and the closing oil passage are connected with a main oil passage of a housing through the upper hinge seat. The lower hinge seat only performs a connection location function and a load bearing function. The convenience and the flexibility of field use are largely improved, and at the same time, the number of backup openings is correspondingly increased and the ability of a user for handling a sudden accident is improved.
Description
Affiliated technical field
The utility model belongs to oil drilling facility parts, is meant a kind of preventer hinge that is used on the oil drilling especially.
Background technology
Preventer is the visual plant during modern oil bores also, and it mainly acts on is the generation that prevents gas blowout accident in drilling process.Ram preventer is a kind of of preventer, and the oil cylinder that it is mainly closed by pressure-bearing shell, side door, flashboard, driving flashboard etc. is formed.The oil circuit of preventer generally is built-in oil circuit, and for the preventer of revolution switch side door, the oil circuit of oil cylinder is to link to each other with working connection on the housing by the upper and lower hinge seat of side door, and the working connection on the housing is positioned at a side of preventer.Because oil circuit position and side outlet position overlap, and make preventer can't arrange side outlet in oil circuit one side.Side outlet can only be positioned at opposite side, makes troubles will for so on-the-spot use of user, is unfavorable for the flexible arrangement of on-the-spot pipeline, also is unfavorable for the emergency processing accident.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved preventer hinge is provided, and it is simple in structure, and is flexible to operation, and result of use is good.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: upper hinge seat, following hinge seat, side door, wherein upper and lower hinge seat is fixedly connected on the housing of preventer, between upper and lower hinge seat, be side door, it is characterized in that: mozzle also is installed in upper hinge seat inside, mozzle one end is connected with the upper hinge seat, and the other end is connected with side door, makes in another road binders road from the upper hinge seat, a road binders road to pass.Following hinge seat is no longer established asphalt channel, and the two-way oil circuit is all finished transmission by the upper hinge seat.
The utility model is taked technique scheme, has following beneficial effect: adopt the inner conduit structure, realized the layout of switch two-way oil circuit dexterously.Open and close two-way oil circuit is all linked to each other with the housing working connection by the upper hinge seat, and following hinge seat only works location and the load-bearing effect of connecting.Its advantage is: the position of side outlet has been avoided in the oil circuit hole, makes the preventer both sides all can arrange side outlet.As double ram type preventer, originally 2 of a side side mouths rise to 2 of every sides, totally 4.Can improve on-the-spot convenience and the flexibility of using so greatly.Also to be equivalent to simultaneously increased standby mouthful quantity, improved the ability that the user handles burst accident.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the utility model structure diagram.
Mark among the figure: hinge seat, 4-side door under 1-mozzle, 2-upper hinge seat, the 3-
The specific embodiment
By shown in Figure 1, the utility model comprises: upper hinge seat 2, following hinge seat 3, side door 4, wherein upper hinge seat 2, following hinge seat 3 are fixedly connected on the housing of preventer, between upper hinge seat 2, following hinge seat 3 is side door 4, in upper hinge seat 2 inside mozzle 1 is installed also, mozzle 1 one ends are connected with upper hinge seat 2, and the other end is connected with side door 4.
The two-way oil circuit of preventer is entered by the end face oil circuit hole of upper hinge seat, and one the tunnel enters the oil circuit hole, bottom of side door through mozzle, and the annular space between another route mozzle and the upper hinge seat enters the top oil circuit of side door.After the two-way oil circuit all concentrates on the upper hinge seat, can make oil circuit hole on the preventer housing avoid the position of preventer side outlet.Thereby can make preventer oil circuit one side also side outlet can be arranged.
