The pipe joint provided has the advantages that the structure is simple, the orientation of a dial plate is random, the reading of the dial plate is convenient, and the leakage is unlikely.

Description

The tensimeter pipe adapter being connected with pipeline
Technical field
The utility model relates to a kind of joint, particularly a kind of tensimeter pipe adapter being connected with pipeline.
Background technology
Existing tensimeter comprises dial plate and the screw thread mounting head being connected with dial plate, during setting pressure table, screw thread mounting head is spun on to associated pipeline port, pipeline inner chamber and tensimeter intracavity inter-connection, can understand the pressure of gas in system (vapour) or liquid by manometric pointer.This connected mode is inconvenient when meter reading, because screwing between tensimeter and pipeline port, otherwise herein can seepage, after tensimeter screws its dial plate towards uncertain, sometimes may, towards a side that is difficult to observation, to meter reading, cause trouble.Sometimes meter reading personnel turn an angle dial plate a little, can cause easily looseningly in meter reading simultaneously, may produce seepage.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, dial plate towards random, meter reading convenient, install firmly, the tensimeter pipe adapter being connected with pipeline of easy to leak not, overcomes the deficiencies in the prior art.
The tensimeter pipe adapter being connected with pipeline of the present utility model, comprise and tighten screw, intermediate connector and lower union joint, intermediate connector has central through hole upper end to have the outer edge extending laterally, this outer edge is positioned at and tightens screw inner side, tighten the inside edge of the oriented medial expansion in lower end of screw, described outer edge is connected with the mutual hook in inside edge; Fluted in intermediate connector upper end, in this groove, be provided with termination O-ring seal; The middle part of intermediate connector is inserted in the center pit of lower union joint and between intermediate connector and lower union joint, is provided with intermediate seal circle; The lower outside of intermediate connector has external thread, and internal thread is arranged at the bottom of lower union joint center pit, and intermediate connector is threaded by this with lower union joint; The lower outside of lower union joint has external thread and is threaded with lower fastening screw by this external thread, the boss in the oriented outside of end periphery on lower linking tube, this boss is positioned at the inner side of lower fastening screw, the boss of the oriented inner side of lower end periphery of lower fastening screw, boss is laterally connected with the mutual hook of boss to the inside, between lower linking tube and the termination of lower union joint, is provided with lower seal.
The tensimeter pipe adapter being connected with pipeline of the present utility model, during installation, the pipeline port of system is connected by welding manner with lower linking tube, intermediate connector and lower union joint are by screw threads for fastening and install intermediate seal circle additional, screw thread mounting head on tensimeter with tighten screw and pass through screw threads for fastening, the end face of screw thread mounting head is squeezed on the termination O-ring seal in the groove of intermediate connector upper end, and lower fastening screw and lower union joint screw and clamp lower seal after determining at tensimeter.Have advantages of simple in structure, dial plate towards random, meter reading convenient, install firmly, easy to leak not.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation that tightens screw shown in Fig. 1;
Fig. 3 is the structural representation of the intermediate connector shown in Fig. 1.
Embodiment
As shown in Figure 1, 2, 3: 3 for tightening screw, 7 is intermediate connector, and 8 is lower union joint.Intermediate connector 7 has central through hole 15 upper end to have the outer edge 14 extending laterally, and this outer edge 14 is positioned at and tightens screw 3 inner sides, tightens the inside edge 13 of the oriented medial expansion in lower end of screw 3, and outer edge 14 is connected with the mutual hook in inside edge 13.
Fluted in intermediate connector 7 upper ends, in this groove, be provided with termination O-ring seal 4.
The middle part of intermediate connector 7 is inserted in the center pit of lower union joint 8 and is provided with intermediate seal circle 5 between intermediate connector 7 and lower union joint 8.
The lower outside of intermediate connector 7 has external thread, and internal thread is arranged at the bottom of lower union joint 8 center pits, and intermediate connector 7 is threaded by this with lower union joint 8.
The lower outside of lower union joint 8 has external thread and is threaded with lower fastening screw 10 by this external thread, the boss in the oriented outside of end periphery on lower linking tube 11, this boss is positioned at the inner side of lower fastening screw 10, the boss of the oriented inner side of lower end periphery of lower fastening screw 10, boss is laterally connected with the mutual hook of boss to the inside.Between lower linking tube 11 and the termination of lower union joint 8, be provided with lower seal 9.
During installation, the pipeline port one 2 of system is connected by welding manner with lower linking tube 11, intermediate connector 7 and lower union joint 8 are by screw threads for fastening and install intermediate seal circle 5 additional, screw thread mounting head on tensimeter 12 with tighten screw 3 and pass through screw threads for fastening, the end face of screw thread mounting head 2 is squeezed on the termination O-ring seal 4 in intermediate connector 7 upper end grooves, and lower fastening screw 10 screws and clamp lower seal 9 with lower union joint at tensimeter 1 after determining.In system operational process, during meter reading, as dial side needs to adjust, can tighten the rear rotation pressure table 1 of screw 3 by loosening, it is reached towards suitable position, the more fastening screw 3 that tightens, in rotation process, can there is not loose leaky phenomenon.Have advantages of simple in structure, dial plate towards random, meter reading convenient, install firmly, easy to leak not.
