Abstract
A clamping sleeve type pipe connector for a pressure gage comprises an upper fastening nut, a middle connector and a lower connector, a central through hole is formed in the middle connector, an outer edge extending towards the outer side is arranged at the upper end of the middle connector, the outer edge is located on the inner side of the upper fastening nut, an inner edge stretching towards the inner side is arranged at the lower end of the upper fastening nut, and the outer edge and the inner edge are connected in a hooking mode. A groove is formed in the upper end of the middle connector, and an end seal ring is arranged in the groove. The middle portion of the middle connector is inserted into a central hole of the lower connector, and a lower seal ring is arranged between the middle connector and the lower connector. The middle connector is connected with the lower connector through threads. Outer threads are arranged on the outer side of the lower portion of the lower connector, the lower connector is in threaded connection with a lower fastening nut through the outer threads, a clamping sleeve is arranged in the lower fastening nut, a conical surface is arranged in an inner hole of the lower portion of the lower connector, and an outer conical surface matched with the conical surface is arranged on the outer side of the upper end of the clamping sleeve. The clamping sleeve type pipe connector for the pressure gage has the advantages that the structure is simple, the orientation of a gage disk is free, and the pressure gage can be read conveniently.
Description
Technical field
The utility model relates to a kind of joint, particularly a kind of bite type manometer tube joint.
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 bite type manometer tube joint of easy to leak not, overcomes the deficiencies in the prior art.
Bite type manometer tube joint 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 is provided with lower seal between intermediate connector and lower union joint; The lower outside of intermediate connector has external thread, and lower union joint center pit has internal thread, 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, in lower fastening line mother, is provided with cutting ferrule, and endoporus place, lower union joint bottom is provided with the conical surface, and there is the male cone (strobilus masculinus) matching with the conical surface in outside, cutting ferrule upper end.
Bite type manometer tube joint of the present utility model, during installation, the pipeline connecting pipe termination of system is inserted in lower clamp nut and cutting ferrule, intermediate connector and lower union joint are by screw threads for fastening and install lower seal 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, lower fastening screw is with lower union joint screws after determining at tensimeter and clamp cutting ferrule by the conical surface, and cutting ferrule is fastened on outside the pipeline connecting pipe of system.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;
Fig. 4 is the structural representation of the lower union joint 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 14 upper end to have the outer edge 12 extending laterally, and this outer edge 12 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 12 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 lower seal 5 between intermediate connector 7 and lower union joint 8.
The lower outside of intermediate connector 7 has external thread, and lower union joint 8 center pits have internal thread, 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, in lower fastening line mother 10, is provided with cutting ferrule 9, and lower union joint 8 endoporus places, bottom are provided with the conical surface 15, and there is the male cone (strobilus masculinus) matching with the conical surface 15 in cutting ferrule 9 outsides, upper end.The lower end of cutting ferrule 9 leans in the inner side of lower fastening screw 10 and leans place for conical surface contact.
During installation, the pipeline connecting pipe termination 11 of system is inserted in lower clamp nut 10 and cutting ferrule 9, intermediate connector 7 and lower union joint 8 are by screw threads for fastening and install lower seal 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, lower fastening screw 10 screws and passes through the conical surface 15 at tensimeter 1 with lower union joint 8 and clamps cutting ferrule 9 after determining, and makes cutting ferrule 9 be fastened on pipeline connecting pipe 11 outsides of system.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.
