Abstract
Description
Technical field
The present invention relates to a kind of detecting device, particularly a kind of pressure gauge tester.
Background technology
The quality of electro connecting pressure gauge is the experience according to worker always, or more renews tensimeter and conclude in the mode contrasting, but often can cause erroneous judgement with this kind of judgment mode, to applying unit, brings unnecessary loss, fritters away energy and financial resources.
Summary of the invention
Problem to be solved by this invention is to provide a kind of letter to answer practicality and the high pressure gauge tester of accuracy rate.
In order to address the above problem, the invention provides a kind of pressure gauge tester, for being connected with the joint of testing pressure table, comprise for transmitting the also air chamber of accommodating gas, described air chamber has relative two ends, its one end is connected with for be filled with the valve of gas in air chamber, the other end with for being connected the detachable connection of connector of described testing pressure table, described connector at least has three links that are connected, its first link is connected with air chamber, the second link is connected with the joint of testing pressure table, the 3rd link is connected with the joint of master gauge for as object of reference.
As preferably, described air chamber is steel pipe, described valve is circular tube shaped, one end that described steel pipe is connected with described valve is blind end, described blind end is provided with a through hole being connected for the one end with described valve, and the other end of described air chamber is provided with the screw thread for being threaded with the first link of described connector.
As preferably, described connector is threeway, its first link is provided with the screw thread for being threaded with the described air chamber other end, its second link is connected with the first controlled valve of introducing the gas in described testing pressure table for controlling, and its 3rd link is connected with the second switch valve of introducing the gas in described master gauge for controlling.
As preferably, the second link of described connector is connected by the X-over controlled valve corresponding with it respectively with the 3rd link, between the described X-over controlled valve corresponding with it respectively by silk is connected.
The beneficial effect of pressure gauge tester of the present invention is, simple in structure, only by air chamber, connector and valve, formed this detecting device, after testing pressure table is connected with this detecting device, by valve, in testing pressure table, introduce gas to detect, more accurate for making to detect, this detecting device is also provided with for contrasting the master gauge of reference, and the variation of observing testing pressure table and normal pressure list index in isobaric situation is with the further quality of definite testing pressure table.In addition, be also provided with controlled valve only valve closing can need be changed when changing tensimeter, without exitting or avoid occurring disappointing situation when changing tensimeter.If the link of connector does not mate with controlled valve size, can be by X-over being set and silk being solved.
Accompanying drawing explanation
Fig. 1 is the structural representation of pressure gauge tester of the present invention.
Reference numeral:
1-air chamber; 2-valve; 3-connector; 4-X-over; 5-is to silk; 6-testing pressure table; 7-master gauge; 8-the first controlled valve; 9-second switch valve; 10-joint.
Embodiment
Below in conjunction with accompanying drawing, pressure gauge tester of the present invention is described in detail.
The present invention discloses a kind of pressure gauge tester, for being connected with the joint 10 of testing pressure table 6, this pressure gauge tester comprises for transmitting the also air chamber 1 of accommodating gas, this air chamber 1 has relative two ends, its one end is connected with for be filled with the valve 2 of gas in air chamber 1, the other end with for being connected the detachable connection of connector 3 of testing pressure table 6, this connector 3 at least has three links that are connected, its first link is connected with air chamber 1, the second link is connected with the joint 10 of testing pressure table 6, the 3rd link is connected with the joint 10 of master gauge 7 for as object of reference.Namely, when each detection, only testing pressure table 6 need be communicated with to introduce gas with the second link of connector 3, by the pointer variation of observation caliber tensimeter 7 and the pointer of testing pressure table 6, change the quality that can accurately judge testing pressure table 6.
Further, air chamber 1 in the present embodiment is a steel pipe, for circular tube shaped, (valve 2 in the present embodiment is a mini diameter tube to valve 2, its material also can be steel), one end that this steel pipe (being air chamber 1) is connected with valve 2 is blind end, this blind end is provided with a through hole being connected for one end of the valve 2 with circular tube shaped, because the valve 2 in the present embodiment is iron and steel material quality, therefore it welds to fix by an end and the outer rim of being located at the through hole on air chamber 1.The other end of this air chamber 1 is provided with the screw thread for being threaded with the first link of connector 3.Connector 3 in the present embodiment is threeway, its first link is provided with the screw thread for being threaded with air chamber 1 other end, its second link is connected with the first controlled valve 8 of introducing the gas in testing pressure table 6 for controlling, and its 3rd link is connected with the second switch valve 9 of introducing the gas in master gauge 7 for controlling.
Because the bore of air chamber 1 is conventionally larger, therefore the bore of each link of threeway is also just corresponding larger, for being better connected with the first controlled valve 8, second switch valve 9, the second link of connector 3 is connected by X-over 4 controlled valve corresponding thereto respectively with the 3rd link, between this X-over 4 controlled valve corresponding thereto, also pass through respectively silk 5 to connect, with the controlled valve of the more different model of adaptation.
During concrete enforcement, testing pressure table 6 is connected with connector 3, air chamber 1 is connected with valve 2 and is inflated in air chamber 1 by valve 2, open the first controlled valve 8 and second switch valve 9, along with the rising of air chamber 1 internal gas pressure can be observed the situation of indicator indication high pressure, by the quality of this testing pressure table 6 of the contrast judgement with master gauge 7, then air chamber 1 and valve 2 are disconnected, gas is gushed by valve 2, along with the situation of the reduction observation low pressure indicator indication low-voltage of air chamber 1 internal gas pressure, same by judging with comparing of master gauge 7.
Adopt pressure gauge tester of the present invention to testing pressure table, to detect fast and accurately, and this pressure gauge tester is simple in structure, easy to operate, greatly improved work efficiency.
Above embodiment is only exemplary embodiment of the present invention, is not used in restriction the present invention, and protection scope of the present invention is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the present invention in essence of the present invention and protection domain, this modification or be equal to replacement and also should be considered as dropping in protection scope of the present invention.
