Description
Technical Field
The utility model discloses a pressure boost pressure relief device is the improvement to manual hydraulic pump, belongs to the safety inspection device field.
Background
The pressure container of the boiler needs a hydraulic test, the prior art is that a manual hydraulic pump is connected with a product needing hydraulic pressure, water is injected into the product, the hydraulic pump is manually controlled to be pressed upwards, and the manual operation is stopped after the pressure value is reached.
Disclosure of Invention
The utility model aims at providing an automatic pressure boost pressure relief device to solve manual water pressure mode, can not accomplish automatic technical problem such as pressure-up, pressure maintenance, automatic pressure release.
In order to achieve the above purpose, the technical solution adopted by the present invention is as follows:
the automatic pressure boosting and relieving device comprises a PLC (programmable logic controller) 1, a pressure value control display table 2 for setting a required pressure value before a hydrostatic test, a pressure maintaining timer 3 for setting required pressure maintaining time, a booster pump 6, a pressure switch 5, a pressure release valve 4, a tap water input 7 and a hydraulic pressure output 8; the pressure value control display table 2 is connected with the PLC 1; tap water input 7 leads to pipe and water source connection, the tap water input 7 other end is connected with 6 one end of booster pump, the 6 other end of booster pump is connected with 8 one ends of water pressure output, back water pressure product is connected to the 8 other ends of water pressure output, booster pump 6 still with pressure switch 5 series connection between tap water input 7 and relief valve 4, after water pressure reaches the set pressure value, pressure switch 5 closure signal feeds back to PLC control 1, PLC control 1 controls 6 stop work of booster pump and carries out the pressurize, when the pressurize begins, PLC control 1 sends out the signal to pressurize time-recorder 3, begin the pressurize countdown, after the countdown, PLC control 1 controls pressure switch 5 to open, PLC control 1 still controls relief valve 4 and carries out the pressure release, whole pressure boost has been accomplished, the pressure release process.
The utility model discloses an advantage and positive effect: the hydraulic structure of the traditional container is changed; automation is realized in the process of water pressure of the container. An operator only needs to connect equipment, sets a pressure value, and the whole pressurizing and pressure releasing process can be automatically completed after the device runs. Personnel in the whole process do not need to be close to the water pressure product, and the whole water pressure process can be checked through the display meter, so that the personnel safety is ensured, and the working efficiency is improved.
Drawings
Fig. 1 is a schematic view of the working principle and structure of the present invention.
In the figure: 1. PLC control; 2, displaying a table; 3, a pressure maintaining timer; 4. a pressure relief valve; 5. a pressure switch; 6. a booster pump; 7. inputting tap water; 8. and (5) water pressure output.
Detailed Description
The utility model discloses a concrete structure is seen in figure 1, and pressure boost pressure relief device PLC controls 1 control display table 2, sets for the pressure value that the product required through display table 2 before the hydrostatic test, sets for the dwell time that the product required in the pressurize time-recorder 3. Tap water input 7 connects the water pipe, guarantee the water source of whole water pressure process, tap water input 7 is connected with booster pump 6, water pressure product after 8 connection of water pressure output, pressure switch 5 is connected back water pressure with booster pump 6 and is reached set for pressure value back pressure switch 5 closed signal feedback PLC control 1, 6 stop work of PLC control 1 control booster pump carry out the pressurize, 3 start the pressurize countdown of PLC control 1 control pressurize timer, after the countdown is finished, PLC control 1 control pressure switch 5 is opened, PLC control 1 control relief valve 4 carries out whole pressure boost of pressure release work completion, the pressure release process.
The device sets a pressure value on a display meter through PLC control, and the pressure maintaining timer sets pressure maintaining time. After the set pressure is reached, the pressure switch feeds a signal back to the display meter, the pressure maintaining timer starts to count down, and after the count down is finished, the pressure relief valve works to discharge water to complete the functions of automatic pressure up, pressure maintaining and automatic pressure relief.
