Abstract
The invention discloses a pipe joint for a pressure gauge. The pipe joint for the pressure gauge comprises an upper fastening screw nut, a middle connector and a lower connector, wherein the middle connector is provided with a center through hole, the upper end of the middle connector is provided with an external edge which stretches to the outer side, the external edge is positioned at the inner side of the upper fastening screw nut, the lower end of the upper fastening screw nut is provided with an internal edge which stretches to the inner side, and the external edge and the internal edge are mutually connected in a hooking way; a groove is arranged at the upper end of the middle connector and is internally provided with an end sealing ring; the middle part of the middle connector is inserted into a center hole of the lower connector, and a lower sealing ring is arranged between the middle connector and the lower connector; external threads are arranged at the outer side of the lower part of the middle connector, internal threads are arranged at the lower part of the center hole of the lower connector, and the middle connector and the lower connector are connected through the external threads and the internal threads; external threads are arranged at the outer side of the lower part of the lower connector. The pipe joint for the pressure gauge, disclosed by the invention, has the advantages that the structure is simple, the orientation of a gauge plate is optional, the reading of the pressure gauge is convenient, the installation is firm, and the leakage is unlikely to occur.
Description
Technical field
The present invention relates to a kind of joint, particularly a kind of tensimeter pipe adapter.
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 associated connector, gas on connector (vapour) or fluid passage 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 tensimeter and connector must screw, 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 of easy to leak not, overcomes the deficiencies in the prior art.
Tensimeter pipe adapter 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 lower seal 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.
Tensimeter pipe adapter of the present invention, during installation, lower union joint is connected by screw threads for fastening with connector, be provided with packing ring between lower union joint and connector, intermediate connector and lower union joint are by screw threads for fastening and install lower seal additional, the screw thread mounting head on tensimeter with tighten screw by 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, during installation by manometric towards determining, tighten and tighten screw and get final product.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 12 upper end that the outer edge 11 extended is laterally arranged, and this outer edge 11 is positioned at and tightens screw 3 inboards.Tighten the inside edge 10 of the oriented medial expansion in lower end of screw 3, outer edge 11 is connected with the mutual hook in inside edge 10.
Fluted in intermediate connector 7 upper ends, be provided with O type 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 lower seal 5 between intermediate connector 7 and lower union joint 8.Lower seal 5 is positioned at the groove in intermediate connector 7 outsides.
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.
During installation, lower union joint 8 is connected by screw threads for fastening with connector 6, be provided with packing ring 9 between lower union joint 8 and connector 6, 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, during installation by tensimeter 1 towards determining, tighten and tighten screw 3 and get final product.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.
