Abstract

The utility model discloses a manometer detector, comprising a standard meter, air passages, a front-end decompressor and a fine adjustment decompressor, wherein a compressed air inlet is arranged on the front-end decompressor, and the outlet of the front-end decompressor is connected with the fine adjustment decompressor through the air passage; the air passage at the outlet of the fine adjustment decompressor is divided into two passages, one passage is connected with the standard meter, and the other passage is provided with a calibrated manometer interface. The front-end decompressor of the manometer detector obtained from the utility model is used for decompression, the pressure of an air source is decompressed to the rated pressure of an instrument, the fine adjustment decompressor can carry out fine adjustment for air pressure in the range of the rated pressure, and therefore every pressure value in the range of the rated pressure can be provided for a calibrated meter and standard meters. The manometer detector of the utility model is simple to operate and accurate to adjust the pressure, and the manometer detector can be used for detection on production sites.

Description

The tensimeter detector

Technical field

The utility model relates to a kind of detector, especially a kind of tensimeter detector.

Background technology

Tensimeter uses very extensively in industrial processes, can produce error because tensimeter is in use accumulated, and produce situations such as part skew, linear change thus, so tensimeter needs periodically detection check.Existing tensimeter detection check adopts the hydraulic pump simulation to produce oil pressure usually, utilizes the comparison of calibrated meter and standard scale to carry out detection check.There is following defective in such mode:

1, hydraulic pump simulation generation oil pressure must carry out in the laboratory, calibrated meter dismounting back need be concentrated and deliver to calibration chamber, and workload is bigger;

2, the operation of the detection check device of hydraulic pump formula is comparatively loaded down with trivial details, and detection efficiency is lower; Need be when detecting to carrying out strict seal everywhere, because the in use long-term pressurized of whole device can cause whole device sealing to descend after therefore long-time the use;

3, oil pressure is difficult for stable control, because the existence of leakage phenomenon can not make pressure keep for a long time at some point usually, has brought inconvenience to pressure calibration.

Therefore, be necessary existing tensimeter detection mode is improved.

Summary of the invention

The purpose of this utility model is that a kind of simple to operate, the pressure that design for the deficiency that solves above-mentioned technology are regulated tensimeter detector accurate, that can detect in the production scene.

The tensimeter detector that the utility model is designed, comprise standard scale, also comprise gas circuit, front end reliever and fine setting reliever, described front end reliever is provided with compressed air inlet, this front end reliever outlet connects the fine setting reliever by gas circuit, the gas circuit of described fine setting reliever outlet is divided into two, and wherein one the tunnel connects standard scale, and another road is provided with by the school pressure gauge connection.

As preferably, described front end reliever is a pneumatic triple piece; Described fine setting reliever is a needle valve.Pneumatic triple piece generally is made up of air strainer, reduction valve and oil sprayer, can carry out purification filtering and decompression to the source of the gas that enters pneumatic instrument, for instrument offers specified bleed pressure; Needle valve can be finely tuned air pressure in the scope of rated pressure, thereby can compare each pressure calibration point effectively.

The tensimeter detector of the utility model gained, the front end reliever is used for decompression, bleed pressure is decompressed to the rated pressure of giving of instrument, the fine setting reliever can be finely tuned air pressure in the scope of rated pressure, thereby can be calibrated meter and standard scale and provide each force value in the scope of rated pressure; The tensimeter detector of the utility model gained is compared with the prior oil pressure calibrating mode also has following advantage:

1, easy to operate, with low cost;

2, therefore the pressurized air that can utilize the production scene can detect at the scene as the school measuring pressure, need not to deliver to the laboratory, thereby effectively alleviate work load;

3, brother is more stablized, filled to compressed air source pressure, even pressure produces fluctuation, also can become rated pressure stably after through the decompression of front end reliever, can for a long time pressure be kept at some point, and it is more accurate to calibrate.

Description of drawings

Fig. 1 is embodiment 1 structural representation;

Fig. 2 is embodiment 2 structural representations;

Among the figure: standard scale 1, gas circuit 2, front end reliever 3, fine setting reliever 4, by school pressure gauge connection 5, pneumatic triple piece 6, needle valve 7, tested tensimeter 8.

Embodiment

The utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1:

As shown in Figure 1, the described tensimeter detector of present embodiment, comprise standard scale 1, also comprise gas circuit 2, front end reliever 3 and fine setting reliever 4, described front end reliever 3 is provided with compressed air inlet, and these front end reliever 3 outlets connect fine setting reliever 4 by gas circuit 2, and the gas circuit 2 of described fine setting reliever 4 outlets is divided into two, wherein one the tunnel connects standard scale 1, and another road is provided with by school pressure gauge connection 5.

The described tensimeter detector of present embodiment, front end reliever 3 is used for decompression, bleed pressure is decompressed to the rated pressure of giving of instrument, fine setting reliever 4 can be finely tuned air pressure in the scope of rated pressure, thereby can be calibrated meter and standard scale 1 and provide each force value in the scope of rated pressure; The tensimeter detector of the utility model gained is compared with the prior oil pressure calibrating mode also has following advantage: 1, easy to operate, with low cost; 2, therefore the pressurized air that can utilize the production scene can detect at the scene as the school measuring pressure, need not to deliver to the laboratory, thereby effectively alleviate work load; 3, brother is more stablized, filled to compressed air source pressure, even pressure produces fluctuation, also can become rated pressure stably after through 3 decompressions of front end reliever, can for a long time pressure be kept at some point, and it is more accurate to calibrate.

Embodiment 2:

As shown in Figure 2, the described tensimeter detector of present embodiment, described front end reliever 3 is a pneumatic triple piece 6; Described fine setting reliever 4 is a needle valve 7.Pneumatic triple piece 6 is made up of air strainer, reduction valve and oil sprayer, can carry out purification filtering and decompression to the source of the gas that enters pneumatic instrument, for instrument offers specified bleed pressure; Needle valve can be finely tuned air pressure in the scope of rated pressure, thereby can compare each pressure calibration point effectively, and other are with embodiment 1.
