The length at relief valve center is set to 500mm.
Compared with prior art, the technical solution of the utility model is had the benefit that
(1), in this utility model, because union form is consistent in the connector of two kinds of forms, union end face is away from safety simultaneously
Valve Center Length is consistent to be used it is ensured that smoothly changing mutually, can be prevented effectively from because of homing position type relief valve and shearing safety
Valve can not general and occur cannot change in time impact drilling well timeliness problem；
(2) this utility model be prevented effectively from because shearing relief valve and homing position type relief valve can not general and occur cannot and
Shi Genghuan affects the problem of drilling well timeliness；
(3) this utility model can reduce the quantity of back-up safety valve, has saved cost.

Specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
The connector that slush pump homing position type relief valve of the present utility model and shearing relief valve are used interchangeably, according to such as
The form of two shown in Fig. 1 and Fig. 2 kind relief valve and size, design two kinds of different connectors, in pipeline designs of releasing, making
During according to the corresponding connector of formal character of relief valve ensure install.
Embodiment one
When this utility model be used as shearing relief valve connector when, as shown in Figure 3 and Figure 4, described connector include by
Flange 3, short tube 4 and union 5 that left-to-right is sequentially connected.The shearing safety that the geomery of described flange 3 is connected with it
The geomery of valve 1 terminal port flange is identical, and described flange 3 may be configured as circle.Described short tube 4 can be made up of chrome molybdenum material, institute
The length stating short tube 4 can be designed according to shearing relief valve 1 interface length, and the external diameter of described short tube 4 may be configured as
114mm, wall thickness may be configured as 19mm.The geomery of described union 5 can be designed according to the pipeline of releasing being connected.
Embodiment two
When this utility model be used as homing position type relief valve connector when, as shown in Figure 5 and Figure 6, described connector include by
Flange 3, short tube 4 and union 5 that left-to-right is sequentially connected.The homing position type safety that the geomery of described flange 3 is connected with it
The geomery of valve 2 terminal port flange is identical, and described flange 3 may be configured as square.Described short tube 4 can be made up of chrome molybdenum material, institute
The length stating short tube 4 can be designed according to homing position type relief valve 2 interface length, and the external diameter of described short tube may be configured as 114mm,
Wall thickness may be configured as 19mm.The geomery of described union can be designed according to the pipeline of releasing being connected.
