Abstract
The utility model relates to a safety interlocking device for meshed quick opening doors and pressure vessels, which comprises a pressure vessel and a quick opening door which is in interlocking connection with the pressure vessel, wherein the pressure vessel is provided with an air exhaust ball valve which is provided with a handle; the quick opening door is provided with positioning slots corresponding to the handle. One side of the pressure vessel is provided with a cylinder, and the quick opening door is provided with a lock hole which is matched with a cylinder rod of the cylinder. The limit position of the handle is provided with a proximity switch which controls the outward extension of the cylinder rod through a control circuit. The pressure vessel is provided with a pressure gauge which controls the backward retraction of the cylinder rod through the control circuit. The limit position of the outward extension of the cylinder rod is provided with a proximity switch which controls the opening and closing of air admission holes of the pressure vessel through the control circuit. The utility model adopts the manual and electric double safety method, so when electric protection fails, normal work can be carried out with manual protection. Meanwhile, under the condition of power failure, the electric protection has no function and manual operation can be used for safety production.
Description
Affiliated technical field
The utility model relates to a kind of meshing-teeth quick-open pressure vessel safety interlock.
Background technique
Meshing-teeth quick-open pressure vessel is widely used in the typing of food sterilization, the vulcanization of rubber and timber, socks.Need be during its work to feeding high pressure-temperature gas in the pressurized container, after finishing, work needs pressurized gas emptying and container is opened from pressurized container by quick operating valve.If there is not the protection of safety interlock, the gas in pressurized container does not also have under the situation of emptying, and the workman sometimes can misoperation open quick operating valve, thereby causes dangerous accident.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and a kind of meshing-teeth quick-open pressure vessel safety interlock with duplicate protection effect is provided.
The utility model comprises pressurized container and the quick operating valve that is connected with pressurized container, pressurized container and quick operating valve carry out interlock by engaging tooth, its technical solution is to be provided with venting ball valve on pressurized container, ball valve is provided with handle, on quick operating valve, be provided with simultaneously a location slot corresponding with handle, when pressurized container and quick operating valve mesh fully, handle and location slot over against; Side at pressurized container is provided with cylinder, is provided with simultaneously cylinder rod with this cylinder lockhole that matches in the quick operating valve position relative with cylinder, when pressurized container and quick operating valve mesh fully, cylinder rod and lockhole over against; The limit position that enters the location slot at handle is provided with near switch, should be near switch stretching out by control circuit control cylinder rod, on pressurized container, also be provided with pressure gauge, pressure gauge is by the withdrawal of control circuit control cylinder rod, the limit position that stretches out in cylinder rod is provided with near switch, and this is near the keying of switch by control circuit pilot pressure container inlet hole.
Adopt above-mentioned pressurized container to adopt the dual fail-safe setting, when quick operating valve and pressurized container do not arrive engagement fully, handle can not enter into the location slot, this moment, venting ball valve was in the state of unlatching, also can be drained by drain tap if having gas to hinder for some reason to enter pressurized container.When quick operating valve and pressurized container reach complete engaging position, handle can be by the correct location slot that inserts, be positioned at the also lockhole on the quick operating valve of cylinder rod of the cylinder of pressurized container one side, handle drives drain tap and closes, be positioned at being switched on of handle limit position simultaneously near switch, be activated by the control circuit cylinder, cylinder rod is stretched out and is entered in the lockhole on the quick operating valve, make and be positioned at being switched on of cylinder rod limit position near switch, the suction port of pressurized container is opened, show all safety this moment, can be to feeding pressurized gas in the pressurized container.Any one link can not reach the requirement pressurized container and will not allow to feeding gas in the above-mentioned working procedure.When needs are opened quick operating valve, earlier with the handle pull-up, drain tap is opened, residual gas is released by drain tap in the pressurized container, and when the gas pressure in the pressurized container was zero, pressure gauge passed to control circuit with signal, make cylinder work with cylinder rod by withdrawing from the lockhole, at this moment, show pressurized container safety, can open quick operating valve.Any one link can not reach the requirement quick operating valve and can not be unlocked in the above-mentioned working procedure.
The utility model has adopted the measure of manual and electronic dual fail-safe, still can carry out proper functioning by manual protection when electronic protection is broken down.Under the situation of outage, also can keep the safety in production when electronic protection is inoperative simultaneously by manual operations.
