Abstract
The utility model relates to an automatic presser which belongs to the detecting device for the pressure of a pressure vessel. A box body provided with wheels is adopted; two two-position three-way valves, a pressure meter and three air-operated elements communicated with the two two-position three-way valves are installed on the box body; an air storage tank connected with the two-position three-way valves is installed in the box body, and the two-position three-way valves are connected with an air inlet pipe extended out of the box body and connected with an air compressor. A gas-liquid pressurizing cylinder is also arranged in the box body, wherein, a big air cylinder end is connected with the other two-position three-way valve, and a small air cylinder end is provided with a connecting tube extended out of the box body and connected with the pressure vessel. A small amount of compressed air can be used by the presser to detect the pressure of a big vessel, and the high hydraulic pressure detection can be obtained by using the minor atmospheric pressure under the adoption of a big and a small dual pistons. The utility model has the advantages of small volume, light weight, flexible movement, wide adaptive range, simple operation and convenient use, and the low pressure and the medium pressure can be carried out by the presser.
Description
The utility model belongs to pressurized container and suppresses the detection device class.
Must can dispatch from the factory after qualified through suppressing to detect before pressurized container dispatches from the factory, the present device that pressurized container is suppressed detection has two kinds; A kind of is hand pump, by liquid oils the water in the container is suppressed and is detected; Another kind is a voltage pump, by press water container is suppressed and is detected; With hand pump the big problem of bothersome effort labor intensity is arranged; Container or pipeline are arranged once there is crack pressure in time not stop pressure release with voltage pump, unsafe problem is arranged.
The purpose of this utility model is: provide a kind of save trouble and labor, safe and reliable, be power with pressurized air, the water in the container is suppressed the automatic stamper of detection.
Technical measures of the present utility model are: adopt a casing that has wheel; Pneumatic three element and a pressure gauge of two two position three-way valves, two two position three-way valves of UNICOM are housed on the casing; One and the joining gas cylinder of two position three-way valve are housed in the casing; This two position three-way valve also connects one and stretches out casing and the joining suction tude of air compressor; A pneumohydraulic pressure-cylinder also is housed in the casing, and wherein big cylinder end connects with another two position three-way valve, and little cylinder end has a connecting tube that links with pressurized container that stretch out casing.
1 is that structural representation of the present utility model, Fig. 2 are that side view, Fig. 3 are plan views among the figure.
Fig. 4 is a working principle schematic representation of the present utility model.
2 is the casings that have wheel among the figure, the 1st, and pushing hands; 4 one pressure gauges 5 of pneumatic three element of two two position three- way valves 3 and 6, two two position three-way valves 3 of UNICOM and 6 are housed on casing 2; Pneumatic three element 4 is standard piece, and effect is that pressure is suppressed in water in the filtered air and impurity and adjusting, but oil jet lubrication pressurized cylinder 7 also; One and one of them two position three-way valve 6 joining gas cylinder 10 are housed in casing 2, and this two position three-way valve 6 also connects one and stretches out casing 2 and air compressor 12 joining suction tude 8; A pneumohydraulic pressure-cylinder 7 of being made up of twin-tub cover, double crosslinking piston and return spring also is housed in casing 2; The big cylinder end of pneumohydraulic pressure-cylinder 7 connects with another two position three-way valve 3, and little cylinder end has a connecting tube 9 of joining with tested pressurized container 11 that stretch out casing 2.Pressure gauge 5 is connected on the little cylinder.
When pressurized container is detected, pressurized air by air compressor 12, double crosslinking piston through two position three-way valve 6, pneumatic three element 4, two position three-way valve 3, pneumohydraulic pressure-cylinder 7 is exerted pressure to pressurized container 11 and the pipeline 9 of filling water, pressure is intuitively shown by pressure gauge 5, because the water in the pressurized container 11 is incompressible, so utilize pressurized gas seldom to detect to it; Because small one and large one area of double crosslinking piston does not wait, so can obtain higher hydraulic pressure with less air pressure.Detection is over, and rotates two position three-way valve 3, and a through hole is communicated with atmosphere, pressurized container 11 pressure releases, and double crosslinking piston is retracted the position in the effect bottom right of spring.
The effect of gas cylinder 10 is, is full of pressurized air by air compressor, as bailout gas, under the condition of no air compressor, reinstates gas cylinder 10 as the gas pressure source that detects.This stamper, because therefore pneumatic three-element adjustable in pressure can get low-voltage and medium voltage, Applicable scope is wider.
Claims (1)
