Abstract
The utility model relates to a transition joint of a pressure gauge. The transition joint comprises a transition joint, one end of the transition joint is connected with a body; the adaptor joint is connected on one side of the transition joint. The interiors of the transition joint and an adaptor joint are communicated with each other. The transition joint and the adaptor joint are in threaded connection. Internal screw threads are arranged on one side of the transition joint. Outside threads, matching with the transition joint, are arranged on one side of the adaptor joint. A first sealing ring is arranged between the transition joint and the adaptor joint. According to the utility model, the transition joint of the pressure gauge is simple in structure, convenient in mounting, small in error, high in safety coefficient. When an axial instrument is verified, the joint for vertical transmission is used; the axial pressure gauge is arranged vertically, and reading errors are decreased and instrument repairing is convenient during the verification process.
Description
Technical field
The utility model relates to a kind of web member, particularly a kind of tensimeter X-over.
Background technology
At present, tensimeter is divided into axially according to mounting means and radially, general pressure testers is observed and keeps in repair all more convenient when verification pressure gauge with bottom connection, and when verification pressure gauge with back connection, just there is certain inconvenience, lie in a horizontal plane in checking procedure and can produce certain error, and the pressure gauge with back connection of horizontal positioned exists certain danger when observed reading in verification high pressure gauge, staff's personal safety has been caused to certain hidden danger.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, provides a kind of simple in structure, and installation and maintenance are all more convenient, and error is little, the tensimeter X-over that safety coefficient is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of tensimeter X-over, comprise crossover sub, one end of crossover sub is connected with body, one side of crossover sub is connected with X-over, crossover sub communicates with X-over inside, crossover sub is threaded with X-over, a side at crossover sub is provided with internal thread, a side at X-over is provided with the external thread matching with it, between crossover sub and X-over, be provided with the first O-ring seal or be provided with and be connected neck and connecting portion at crossover sub and X-over adjacent, at connection neck, be arranged with annular groove outward, at connecting portion, be arranged with up and down perforation, in perforation, be provided with location resilient key, location resilient key and annular groove match, at connecting portion, be provided with the second O-ring seal outward, at the second O-ring seal, be provided with compressing member outward.
The utility model compared with prior art has the following advantages:
Simple in structure, to install more conveniently, error is little, safety coefficient is high, when the axial instrument of verification, by using by 90 joints of spending conversion, axial tensimeter is vertically placed, and the error that had both reduced like this reading in the process of verification has also facilitated the repairing to instrument.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of another kind of embodiment of the present utility model;
Number in the figure: 1-crossover sub, 2-X-over, 3-the first O-ring seal, 4-connect neck, 5-connecting portion, 6-annular groove, 7-perforation, 8-location resilient key, 9-the second O-ring seal, 10-compressing member.
embodiment:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1, Fig. 2 shows a kind of embodiment of a kind of tensimeter X-over of the utility model, comprise crossover sub 1, one end of crossover sub 1 is connected with body, one side of crossover sub 1 is connected with X-over 2, crossover sub 1 communicates with X-over 2 inside, crossover sub 1 is threaded with X-over 2, a side at crossover sub 1 is provided with internal thread, a side at X-over 2 is provided with the external thread matching with it, between crossover sub 1 and X-over 2, be provided with the first O-ring seal 3 or be provided with and be connected neck 4 and connecting portion 5 at crossover sub 1 and X-over 2 adjacents, outside connecting neck 4, be arranged with annular groove 6, at connecting portion 5, be arranged with up and down perforation 7, in perforation 7, be provided with location resilient key 8, location resilient key 8 matches with annular groove 6, outside connecting portion 5, be provided with the second O-ring seal 9, outside the second O-ring seal 9, be provided with compressing member 10.
The utlity model has simple in structure, install more convenient, error is little, the advantage that safety coefficient is high, when the axial instrument of verification, by using by 90 joints of spending conversion, axial tensimeter vertically to be placed, the error that had both reduced like this reading in the process of verification has also facilitated the repairing to instrument.
