The present invention relates to a water meter train test apparatus for determining the abnormality of the meter by experimenting whether the position of the meter needle appear in the meter when passing through the water at a uniform pressure of 2KG / ㎠ to the water meter.

In the past, the train test apparatus was operated to be completely manual, which was cumbersome and time consuming when testing the water meter train. "When the water and water pipes are pressurized in contact with each other, the water and water pipes are installed at one end of the mounting table, and the rotary knobs are pressurized and fixed to press the water meter. In this case, the water meter was checked from the tank, and the number displayed on the instrument was checked for abnormality. Therefore, in the case of placing a large number of water meters on the mounting table, the work is very difficult and the rotary knob is operated to closely contact the water meter in series. In case of leaking, many water meters were connected in series and then pressurized, so that the meters located in the middle part of the connected meters were often inflated or escaped upwards. As the water enters from the top, the amount of water in the shank is more Not only is it difficult to check the exact amount of water, but also many defects such as the inability to measure trains of water meters due to misunderstanding when the tank is full, unless the operator visually checks the amount of water in the tank. This was followed.

Therefore, the present invention has been made to solve the above-mentioned drawbacks as described above. "It is extremely easy when pressurizing by connecting a large number of water meters (weakly referred to as" sample ") in series to the type mounting table, and it does not prevent the sample from escaping upward when pressurized. It is the purpose of the present invention to provide a train test apparatus that can automatically prevent power misunderstandings during sample testing by automatically shutting off the power.

Referring to the configuration of the subject innovation for the above purpose according to the accompanying drawings in detail as follows.

Water meter train test apparatus is configured to be connected to the collecting portion (B) of the measuring unit (A), the measuring unit (A) is fixed to the fixing plate (2) on the upper surface of the test table formed of the frame (1) and the fixing plate (2) on the upper surface 2 " "Mount the mounting platform (3) and (3 ') side by side, but perforated a plurality of long holes (4) at equal intervals in the bone of the mounting table (3) and (3') and supported by the two mounting holes (4) The screw portion 6 protruding from the bottom of the pipe 5 is inserted, and the mounting bases 3 and 3 'are kept at a constant distance from the fixing plate 2 so that the nut 7 on the screw portion 6 is fixed. To facilitate the fastening, the fixed blocks 10 and 10 'for fixing the water inlet pipe 8 and the drain pipe 9 are installed at the rear of the mounting table 3 and 3' and the lower end is bent at the front. The lower ends of the operating handles 11 and 11 'are laid on the supports 12 and 12', respectively, and the link 13 is arranged on the bent portions of the operating handles 11 and 11 ', The other end of (13) is arranged in the pressurizing pipe 14 and 14 ', respectively, and the pressurizing pipe 14 and 14' are inserted in the fixed block 15 and the 15 'so that back and forth conveying may be carried out. The rubber pipe 16 is connected to the rear of the pressure pipes 14 and 14 ', and the drain pipe 9 of the water collecting part B is " The sensor sensor 17 on the upper side, the convection valve 18 on the front vertical part, and the opening / closing valve 19 on the lower side of the front vertical part. A small water flow pipe 20 and a water discharge valve 21 are installed in the water flow pipe 20, and a hydraulic pressure gauge 22 and a pressure gauge 23 are installed on the upper end of the drain pipe 9. ), (10 ') and (15), (15') rubber ring (24) is inserted into the back of the collection tank (25) installed in the other end of the drain pipe (9) is installed in the bottom of the collection tank (25) The water level check unit 26 is formed vertically on one side wall of the collecting tank 25, but the water level sensor train 27 is installed at the upper end of the water level fine part 26.

Reference numeral 31 denotes a control box 32, a water meter connection port 33, a water-tight O-ring 34, a drain valve 35, a water meter and 36 (36 ') is a joint pipe.

Referring to the operation and effects of the present invention configured as described above are as follows.

First, before applying power to the device of the present invention, "A large number of water meters (hereinafter referred to as" samples "), which are intended to be tested respectively, are mounted on the mold-mounting bases 3 and 3 ', and the support pipes assembled to the mounting bases 3 and 3' 5) Insert the water meter connection part 32 into one end of the "sample", and when the sample is filled on the mounting table 3 and 3 'in the continuation of the above operation, the operation handles 11 and ( 11 ') to fix the sample. At this time, the links 13 arranged in the cutouts of the operation handles 11 and 11' push the operation tube 14 by pushing the operation handles 11 and 11 '. The sample is firmly fixed by the pressurization of the sample orientation. During the test, the upper lid of the sample must be opened to visually identify the instrument.

And once the sample is fixed to the mounting table (3) and (3 '), the support tube (5) is fixed by the nut (7) so that the sample does not escape from the row and in this state by adjusting the control box 31 At the time of the flow test, the convection valve 18 is closed, the flow valve 21 is opened, and the on-off valve 19 is opened, and the test is performed within about 40 minutes. If the instrument of the sample does not deviate from 2㎏ / ㎠ ± 4 is recognized as a good quality product and if you deviate from 2㎏ / ㎠ ± 4 will be confirmed that the defective product. In addition, during the test, the water passes from the purification tank (not shown) through the water inlet pipe 8 through the samples arranged in a row on the mounting table 3 at a constant pressure. Water passing through (3) is pumped into the pressure pipe (14 ') through the pressure pipe (14) and rubber tube (16) to go to the drain pipe (9) through the sample aligned on the mounting table (3') The outgoing speed and pressure are displayed on the hydraulic pressure gauge 22 and the pressure gauge 23 so that the naked eye can easily check the water, and the water finally flows through the convex pipe 20 to the bottom of the collecting tank 25 to collect the tank. 25) is to be filled, the water is even from the bottom of the collection tank 25 is filled with water through the test device is to make the water level check through the water level check unit 26 is very simple.

And the convection test is performed in the same manner as above in 6 minutes with the convection valve 21 closed and the convection valve 18 opened, in which the instrument should be maintained within the indicated tolerance of 2㎏ / ㎠ ± 2. When the water is filled in the collecting tank 25 and the test continues, the water level sensor 27 mounted on the top of the water level check unit 26 detects this and operates the sensor 17, thereby detecting the sensor 17. It cuts off the power of the control clap 31 and stops the water flowing into the water inlet pipe 8 to prevent the false test occurring at this time. The drain valve 34 installed in the opening to drain the water that is to be used after.

In addition, when testing only one sample on the mounting table (3) and (3 '), the fitting pipes (36) and (36') are fixed blocks (10), (10 ') and (15), respectively. (15 '), and place the sample between the joint pipe (36) and (36') and test in the same way as above, and when the test of the sample under test is completed, turn off the power supply The inflow of water that was introduced into the) is stopped and in this state, the operation handles 11 and 11 'are operated to reverse the pressure tube 14 and then take out the sample.

As described above, the present invention is to simplify the test of the operation condition of the water meter, as well as to prevent the malfunction during the test.
