The manual interlocking device comprises a position switch, orderly arranged manual latches, a latch support, a latch connecting rod and a crank, the electric control alarm device comprises an electric contact pressure gage, an alarm warning lamp and an electric-control box. The utility model has compact structure, early warning function and reliable safety, which is an ideal safety interlocking device for pressure container quick open door.
Description
One, technical field
The utility model relates to a kind of pressure vessel safety device, relates in particular to a kind of pressure vessel of quick opening door safety interlock.
Two, background technique
Existing pressurized container generally can be divided into two kinds, and a kind of is that safety interlock is not housed; Another kind is equipped with safety interlock.And first kind of pressurized container in use, and reason such as malfunctioning or operate miss is opened quick operating valve when also having pressure in container owing to pressure gauge, causes easily that steam is gone out, the scald accident.And the another kind of pressurized container that safety interlock is housed, because of the unreasonable structure of existing safety interlock, operator have in pressurized container and all can open quick operating valve under the stress-free situation and cause the person and equipment accident.
Three, summary of the invention
The utility model is at above-mentioned deficiency, and purpose is to provide a kind of pre-alarm function that has, safe and reliable pressure vessel of quick opening door safety interlock.
For achieving the above object, the technical solution of the utility model is: the pressure vessel of quick opening door safety interlock comprises electric interlocking device, manual interlock and electrical control warning device three parts, all be loaded on Surface Pressure Vessel and continuous by circuit, described electric interlocking device is made up of position limit switch, electromagnet and Electromagnetic bolt, and wherein electromagnet links to each other with Electromagnetic bolt; Manually interlock is made up of position limit switch, manual bolt, plug housing, latch connecting rod, handle, and wherein manual bolt, plug housing, latch connecting rod, handle link to each other successively, and handle links to each other with the surplus valve of the exhaust on the pressurized container; The electrical control warning device is linked to each other by circuit by pressure gauge with electric contact, warning beacon and electric control box and forms.
The utility model optimal technical scheme is: be provided with delay cell in electric control box is, position limit switch is by circuit controling electromagnetism iron and Electromagnetic bolt action simultaneously; Position limit switch and position limit switch are by the work of circuit control warning light; Pressure gauge with electric contact is by the work of circuit control electric control box.
After the utility model adopts technique scheme, its advantage is: only when electric interlocking device and manual interlock are locked fully or separated, pressurized container could work or open, prevent from effectively to have guaranteed the proper functioning or the unlatching of pressurized container because pressure gauge band malfunctioning or that operate miss causes presses off an accident.
Four, description of drawings
Fig. 1 is the signal of the utility model overall structure;
Fig. 2 is installed on structural representation on the pressurized container for the utility model.
Five, embodiment
As shown in Figure 1 and Figure 2, the utility model comprises electric interlocking device, manual interlock and electrical control warning device three parts, all be loaded on Surface Pressure Vessel and continuous by circuit, described electric interlocking device is made up of position limit switch 1, position limit switch 16, electromagnet 2 and Electromagnetic bolt 3, and wherein electromagnet 2 links to each other with Electromagnetic bolt 3; Manually interlock is made up of position limit switch 4, manual bolt 5, plug housing 6, latch connecting rod 7, handle 8, and wherein manual bolt 5, plug housing 6, latch connecting rod 7, handle 8 link to each other successively, and handle 8 links to each other with the surplus valve 9 of the exhaust on the pressurized container; The electrical control warning device is made up of pressure gauge with electric contact 10, warning beacon 11 and electric control box 12.Electromagnetic bolt 3 and manual bolt 5 correspond respectively to pressurized container clip 13 set locking holes 14,15.Simultaneously in electric control box 12, be provided with delay cell.Position limit switch 1 is by circuit controling electromagnetism iron 2 and Electromagnetic bolt 3 actions; Position limit switch 4 and position limit switch 16 are by 11 work of circuit control warning light; Pressure gauge with electric contact 10 is by 12 work of circuit control electric control box.
When pressurized container need be opened, open the outlet valve exhaust on the pressurized container earlier, when treating that the interior pressure of pressurized container is reduced to " 0 " pressure of pressure gauge with electric contact 10 settings, electric control box 12 trigger timing, at this moment extract manual bolt 5, thereby open the residual pressure that the surplus valve 9 of exhaust is got rid of in the pressurized container by handle 8, warning beacon 11 sends acoustooptic alarm, shows to open quick operating valve.When time that time-delay reaches setting during as 1 minute, Electromagnetic bolt 3 withdraws from locking hole 14 automatically, and interlocking is removed, and chimes of doom stops, and can open quick operating valve this moment.And when closing quick operating valve, also must Electromagnetic bolt 3 and manual bolt 5 lock simultaneously and could work, otherwise warning beacon 11 will send acoustooptic alarm.If inflate this moment in pressurized container, because the surplus valve 9 of exhaust is in opening state, gas is discharged by the surplus valve 9 of exhaust, and pressurized container can't boost.
