Description
Technical field
The utility model relates to a kind of pipe joint, especially a kind of pipe joint of carrying high-temperature high-pressure fuel gas to use, specifically a kind of high-temperature high-pressure fuel gas system pipe joint.
Background technique
As everyone knows, for satisfying the system architecture demand, in pneumatic system, need to be extensive use of various pipe joints, structural type commonly used has cap nut to add spherical joint formula and flange join type, its function is the connecting pipeline system, realizes the continuous-flow of fluid in the pipeline and can not leak.Spherical joint is sealed into the linear sealing pattern, because it is simple in structure, sealing is reliable, is usually used in the cooling air system.Flanged joint is sealed into the end face seal pattern, it has the advantage of convenient disassembly, but its volume that takies is bigger, and in the high-temperature high-pressure fuel gas system because the high pressure and the little characteristics of installing space of its working medium, existing various pipe joint all can't satisfy usage requirement, therefore is necessary according to a kind of pipe joint that meets usage requirement of pipeline characteristics design.
Summary of the invention
The purpose of this utility model is can't satisfy the High Temperature High Pressure requirement and have bulky problem at existing all kinds of pipe joints, designs a kind of high-temperature high-pressure fuel gas system pipe joint that can satisfy usage requirement.
The technical solution of the utility model is:
A kind of high-temperature high-pressure fuel gas system pipe joint, it comprises pipe joint 1,4 and cap nut 2, it is characterized in that described pipe joint 1 is provided with the outside thread that the internal thread with cap nut 2 matches, end face at pipe joint 1 is provided with the annular seal groove that seal ring 3 is installed, the end of described pipe joint 4 is provided with step surface, the one side of this step surface contacts with described seal ring 3 and realizes pipe joint 1,4 end face seal, the interior step surface of the another side of described step surface and cap nut 2 offset so that be operated under the effect of cap nut 2 and make pipe joint 1,4 opposing end faces can fit tightly.
On the described cap nut 2 radial stop screw 6 is installed, this radial stop screw 6 revolved the jacket wall of cap nut 2 and the external threaded surface of pipe joint 1 offsets.
Described pipe joint 1 is provided with the step section 7 in the interior step hole of insertion tube joint 4 end faces.
The beneficial effects of the utility model:
The utlity model has simple in structure, easy to connect reliable, the characteristics that radial dimension is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of high-temperature high-pressure fuel gas system pipe joint, it comprises pipe joint 1,4 and cap nut 2, wherein pipe joint 1,4 material can adopt refractory alloy GH1131, cap nut 2 adopts the stainless steel material manufacturing, described pipe joint 1 is provided with the outside thread that the internal thread with cap nut 2 matches, be provided with at the end face of pipe joint 1 and metal o-ring 3(to be installed can to adopt red copper T2M seal ring) annular seal groove, the end of described pipe joint 4 is provided with step surface, the one side of this step surface contacts with described seal ring 3 and realizes pipe joint 1,4 end face seal, the interior step surface of the another side of described step surface and cap nut 2 offset so that be operated under the effect of cap nut 2 and make pipe joint 1,4 opposing end faces can fit tightly.In use loosening in order to prevent cap nut 2, a radial stop screw 6 can be installed on described cap nut 2, on cap nut 2, be provided with a radially screw, radial stop screw 6 revolved the radially screw of cap nut 2 and the external threaded surface of pipe joint 1 offsets, in addition, in order to improve the end face seal effect, in also can an end insertion tube joint 4 during concrete enforcement with pipe joint 1, promptly the end at pipe joint designs a step section 7, pipe joint 4 end faces establish interior step hole of end design, can step hole during connection with step section (forming) the insertion tube joint 4 of pipe joint 1 by little external diameter pipeline section in.Step section 7 has two effects, and the one, guiding is installed, the 2nd, the protection metal o-ring metal o-ring and high-temperature high-pressure fuel gas are isolated, otherwise seal ring is very easily ablated and is lost sealing effect.As shown in Figure 1.
In addition, become flexible phenomenon in order to prevent that cap nut 2 from use producing during concrete enforcement, also can on cap nut, design the lead seal hole 5 that installs the steel ratio, connect the step section 8 that is used for clamping when 1 thread section one side is not provided with an installation at pipe simultaneously, and on this step section 8, also process a lead seal hole 9, on step section 8, can process the plane of clamping simultaneously.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
