Abstract
The utility model discloses a coupling for natural gas engine, including coupling and pipe nut, coupling and pipe nut structure as an organic whole, the left end of coupling is flared type hydraulic pressure coupling structure, and its right -hand member is for having the tapered mouth of pipe, and as an organic whole, and flared type hydraulic pressure coupling matching is connected through spacing step face to this mouth of pipe and pipe nut. The utility model discloses the fungible flared type hydraulic pressure coupling add a rubber tube and realize the connection of two valves, shortened the distance of two valve bodies greatly, saved the space, make arranging of engine more reasonable.
Description
Technical field
This utility model relates to a kind of pipe joint used for natural gas engine, belongs to technical field of automobile engine.
Background technology
The electromagnetic valve class component that natural gas engine uses is more, but the arrangement space on electromotor is very limited. At present, it mostly is sebific duct between low-pressure end (5��9bar) the valve class arranged on natural gas engine to connect, the interface of valve own is respectively arranged with the hydraulic fitting (as described in Figure 2) of flared type, the left end of the hydraulic fitting of this kind of flared type screws in valve body, right-hand member is connected by sebific duct, and all there is the nut 4 supporting with joint at sebific duct (as shown in Figure 3) two ends. Therefore, will reserving two joints between two valves plus the distance of sebific duct length, and the sebific duct product of the special pressure-resistant corrosion-resistant of natural gas engine is in order to ensure that reliability is all harder, cannot do forming tube, this adds difficulty for space layout again.
Summary of the invention
Technical problem to be solved in the utility model is the defect existed for prior art, it is provided that a kind of pipe joint used for natural gas engine.
For solving this technical problem, this utility model provides a kind of pipe joint used for natural gas engine, and including pipe joint and pipe nut, pipe joint and pipe nut are structure as a whole; The left end of described pipe joint is flared type hydraulic fitting structure, and its right-hand member is with the tapered mouth of pipe, and this mouth of pipe and pipe nut are connected as one by limiting stand terrace and mate with flared type hydraulic fitting.
Described pipe joint left end is provided with O-ring seals groove, is screwed on the interface of valve after mounting O-shaped sealing ring.
Described pipe joint right-hand member structure threads directly on the valve interface being provided with flared type hydraulic fitting, it is achieved the connection of two valves.
Beneficial effect: this utility model is alternative, and a flared type hydraulic fitting adds a sebific duct and realizes the connection of two valves, substantially reduces the distance of two valve bodies, saves space, and it is more reasonable to make in the layout of electromotor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of prior art flared type hydraulic fitting;
Fig. 3 is the structural representation of the sebific duct mated with flared type hydraulic fitting.
In figure: 1 pipe joint, 2 pipe nuts, 3O shape sealing ring mounting groove.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is specifically described.
Fig. 1 show structural representation of the present utility model.
This utility model includes pipe joint 1 and pipe nut 2, and pipe joint 1 and pipe nut 2 are structure as a whole.
The left end of described pipe joint 1 is flared type hydraulic fitting structure, consistent with the left side of the common flared type hydraulic fitting shown in Fig. 2.
Described pipe joint 1 left end is provided with O-ring seals groove 3, after mounting O-shaped sealing ring, is screwed on the interface of valve.
The right-hand member of described pipe joint 1 is with the tapered mouth of pipe, and this mouth of pipe and pipe nut 2 are connected as one by limiting stand terrace, and its version is consistent with the two ends of the sebific duct shown in Fig. 3, mates with flared type hydraulic fitting.
Described pipe joint 1 right-hand member structure can thread directly on the valve interface being provided with flared type hydraulic fitting, it is achieved the connection of two valves.
This utility model is alternative, and a flared type hydraulic fitting adds a sebific duct realizes the connection of two valves, substantially reduces the distance of two valve bodies, saves space, and it is more reasonable to make in the layout of electromotor.
This utility model the embodiment above, is merely illustrative, and is not only, and all changes within the scope of this utility model or in equivalent scope of the present utility model are all surrounded by this utility model.
