Abstract
The invention provides a pipe joint connected with a pipeline and applied to a pressure gauge. The pipe joint comprises an upper fastening nut, a middle connector and a lower connector, wherein a central through hole is formed in the middle connector, the upper end of the middle connector is provided with an outer edge extending outwards, the outer edge is arranged on the inner side of the fastening nut, the lower end of the upper fastening nut is provided with an inner edge extending inwards, and the outer edge and the inner edge are in mutually hooked connection; a sealing ring is arranged at the upper end of the middle connector; the middle part of the middle connector is inserted in a central hole of the lower connector and is provided with a middle sealing ring; the lower part of the middle connector is in threaded connection with the lower part of the central hole of the lower connector; the lower connector and the lower fastening nut are in threaded connection, an outward boss is arranged on the periphery of the upper end of a lower connection pipe and is arranged on the inner side of the lower fastening nut, an inward boss is arranged on the periphery of the lower end of the lower fastening nut and is in mutually hooked connection with the outward boss, and a lower sealing ring is arranged between the end heads of the lower connection pipe and the lower connector. The pipe joint provided by the invention 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
Technical field
The present invention relates to a kind of joint, particularly a kind of tensimeter pipe adapter be connected with pipeline.
Background technology
Existing tensimeter comprises dial plate and the screw thread mounting head be connected with dial plate, during the setting pressure table, the 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 inconvenience 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 being difficult to a side of observing, to meter reading, cause trouble.Sometimes the meter reading personnel turn an angle dial plate a little, in meter reading, can cause easily looseningly simultaneously, may produce seepage.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, dial plate towards random, meter reading convenient, install firmly, the tensimeter pipe adapter be connected with pipeline of easy to leak not, overcomes the deficiencies in the prior art.
The tensimeter pipe adapter be connected with pipeline of the present invention, comprise and tighten screw, intermediate connector and lower union joint, intermediate connector has central through hole upper end that the outer edge extended is laterally arranged, this outer edge is positioned at and tightens the screw inboard, 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 the intermediate connector upper end, be provided with the termination O-ring seal in this groove; The middle part of intermediate connector is inserted in the center pit of lower union joint and is provided with the intermediate seal circle between intermediate connector and lower union joint; 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 inboard of lower fastening screw, the boss of the oriented inboard of lower end periphery of lower fastening screw, boss laterally is connected with the mutual hook of boss to the inside, between the termination of lower linking tube and lower union joint, is provided with lower seal.
The tensimeter pipe adapter be connected with pipeline of the present invention, 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 the 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.
The accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention;
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, and 7 is intermediate connector, and 8 is lower union joint.Intermediate connector 7 has central through hole 15 upper end that the outer edge 14 extended is laterally arranged, and this outer edge 14 is positioned at and tightens screw 3 inboards, 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, be provided with termination O-ring seal 4 in this groove.
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 inboard of lower fastening screw 10, the boss of the oriented inboard of lower end periphery of lower fastening screw 10, boss laterally is connected with the mutual hook of boss to the inside.Be provided with lower seal 9 between the termination of lower linking tube 11 and lower union joint 8.
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 the system operational process, during meter reading, as dial side, need 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 the loose leaky phenomenon can not occur.Have advantages of simple in structure, dial plate towards random, meter reading convenient, install firmly, easy to leak not.
