Abstract

The utility model provides a pressure meter with a calibration interface. A pressure sensitive element is connected to a detection interface through a pipeline extending to the outside of a a meter case; the pressure sensitive element is connected to the detection interface (4) through one switching position of a two-way tee switch valve arranged in the meter case and the pipeline extending to the outside of the meter case; another switching position of the two-way tee switch valve is connected with the calibration interface (5) through a pipeline extending to the outside of the meter case; and the two switching positions of the two-way tee switch valve are used for conducting the pressure sensitive element with the detection interface or with the carlibration interface. In the utility model, the detection interface and the carlibration interface are parallely connected onto the pressure sensitive element, and a switch valve is used for switching states. Compared with the prior art, the pressure meter has the advantages as follows: the switching valve in the pressure meter is used; without disassembly-assembly of the pressure meter, the carlibration to the pressure meter can be accomplished at the original working position of the pressure meter; and during installation, any valve or interface is not needed, therefore the pressure meter is very convenient.

Description

The tensimeter of band calibration interface
Technical field
The utility model relates to a kind of tensimeter, belong to pressure measurement technology field in the physics with calibration interface.
Background technology
Pressure-sensing device in the tensimeter extends the detection interface through force pipe outside watchcase, detect interface and be connected on the pipeline of drawing from system to measure and display system pressure.Need often calibrate at the tensimeter that some occasions is used, with the true pressure of the system that guarantees accurately to reflect the setting pressure table.For the base measuring pressure table, usually the system of tensimeter from measured pressure disassembled.If the calibration cycle once more of defined is shorter, then tensimeter in the short period of time will be by dismounting repeatedly.Such one is to cause unnecessary trouble, the 2nd, make the long cisco unity malfunction of measured pressure system, and the 3rd, the repeated disassembled and assembled tensimeter makes the rising of tensimeter and pressure system failure rate even causes damage.
The innovation and creation content
At above-mentioned deficiency, the utility model will provide a kind of dismounting tensimeter that need not exactly, the tensimeter of the band calibration interface that the original position of using at tensimeter is calibrated.
The tensimeter of the band calibration interface that the utility model provides, the pipeline of pressure-sensing device outside extending to watchcase is connected to the detection interface, pipeline joint detection interface outside extending to watchcase of the two-bit triplet transfer valve of said pressure-sensing device in being installed in watchcase, the pipeline of another of two-bit triplet transfer valve outside extending to watchcase connects calibration interface, and two switching positions of two-bit triplet transfer valve are conducting pressure-sensing device and detection interface or conducting pressure-sensing device and calibration interface.
The tensimeter of the band calibration interface that the utility model provides is a kind of tensimeter that two pressure input interfaces are arranged, and an interface is used to connect tested pressure system, gaging pressure, and another interface is used for manometric calibration.That is to say that the utility model is connected to calibration interface on the pressure-sensing device side by side with detecting interface, and with a transfer valve switching state.Compared with prior art, the transfer valve in the utility model working pressure table need not the dismounting tensimeter, just can finish in the original position of tensimeter work tensimeter is calibrated, and can be installed as the valve or the interface of alignment purpose more when mounted, and is very convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment, among the figure: the 1-tensimeter, the 2-pipeline, joint detection element and transfer valve, the 3-transfer valve, 4-detects interface, 5-calibration interface.
Embodiment
No matter be which kind of tensimeter, the pressure-sensing device of an induction pressure is all arranged in the watchcase, as the most basic reed pipe, corrugated tube etc., this pressure-sensing device has pipeline to be connected with pressure system, so that system pressure acts on pressure-sensing device.Wherein pipeline all is to be extended that watchcase is outer to be connected with system, but according to the difference of purposes, structure, and the different of the big or small and length of caliber are arranged.Said system promptly needs pipeline, container of detected pressures etc.
This routine tensimeter as shown in drawings, in the tensimeter 1 pressure-sensing device is arranged, the interface that pressure-sensing device has pipeline 2 will accept pressure extends to outside the watchcase, this interface of accepting pressure has two, one of them is the detection interface 4 that is used to connect tested pressure system, and another is connected to standard pressure generator and represents the calibration interface 5 that is worth with base measuring pressure when being the base measuring pressure table.Detect interface and calibration interface by on the pipeline that one or two three-way switch valve 3 is connected on pressure-sensing device is connected.Said two-bit triplet transfer valve is installed in the watchcase, two switching position one is the conducting pressure-sensing device and detects interface and cutoff pressure sensitive element and calibration interface, the 2nd, and conducting pressure-sensing device and calibration interface and cutoff pressure sensitive element and detect interface.

Claims (1)

1. tensimeter with calibration interface, the pipeline of pressure-sensing device outside extending to watchcase is connected to the detection interface, a pipeline joint detection interface outside extending to watchcase that it is characterized in that the two-bit triplet transfer valve of said pressure-sensing device in being installed in watchcase, the pipeline of another of two-bit triplet transfer valve outside extending to watchcase connects calibration interface, and two switching positions of two-bit triplet transfer valve are conducting pressure-sensing device and detection interface or conducting pressure-sensing device and calibration interface.
