Abstract
The utility model relates to an over-pressure protector for an electromagnetic instrument pressure container, which is suitable for the over-pressure protection of a pressure container under non corrosive environment, such as a mine air compressor, a boiler, etc. The utility model is mainly composed of a pressure gauge with electric contacts, an electromagnetic performer, a cut-off valve, an audible and visual alarm, etc. One end of a three-way is connected with the pressure container by the cut-off valve, and another end is connected with the pressure gauge with electric contacts by a pipeline. The contact operating pressure of the pressure gauge with electric contacts can be artificially adjusted. A third end of the three-way is connected to one end of the electromagnetic performer, and the other end of the electromagnetic performer is connected with the atmosphere. The utility model has a self-checking function and an audible and visual alarming function, and is convenient to check, maintain and adjust equipment in time.
Description
One, technical field
The utility model relates to electromagnetic instrument tabular form pressurized container overvoltage protective device, is particularly useful for the overvoltage protection to the pressurized container under the non-aggressive environment such as mine air compressor and boiler.
Two, background technique
At present, the employed overvoltage protective device of China's air compressor is a mechanical safety valve, and annual by the quality supervised department verification of adjusting, applying unit can not be adjusted, and does not also know the definite working value of safety valve; The working value of safety valve adjusted is not directly perceived, and the course of action of experimental safe valve is loaded down with trivial details.
Three, technology contents
(1) goal of the invention
The purpose of this utility model provides electromagnetic instrument tabular form pressurized container overvoltage protective device, and this device is made up of electronic device, electromagnetic actuator and other electric elements.Pattern is elegant in appearance, and is rationally distributed.
(2) technological scheme
The utility model electromagnetic instrument tabular form pressurized container overvoltage protective device mainly is made up of the stop valve that links to each other with pressurized container, pressure gauge with electric contact, electromagnetic actuator and electric controller, one end of threeway joins by stop valve and pressurized container, when the device maintenance, can turn-off stop valve, not influence the proper functioning of container; The other end of threeway links to each other with pressure gauge with electric contact by pipeline, and its contact operating pressure of pressure gauge with electric contact can artificially be adjusted.The 3rd of threeway terminates to an electromagnetic actuator one end, and the other end of electromagnetic actuator links to each other with atmosphere.Automatical control system is composed as follows: power supply one end links to each other with the contact of pressure gauge with electric contact by insurance, the other end of pressure gauge with electric contact contact links to each other with an end of the coil of auxiliary reclay, the other end of auxiliary reclay coil links to each other with power supply, like this, after the action of pressure gauge with electric contact contact, make that the auxiliary reclay coil is charged; Power end links to each other with the former limit of a transformer, the secondary of transformer links to each other with the tie point of auxiliary reclay contact and test button by insurance, auxiliary reclay links to each other with the tie point of audible-visual annunciator with the electromagnetic actuator coil with another tie point of test button, audible-visual annunciator links to each other with the other end of transformer secondary output with another tie point of electromagnetic actuator coil, after the middle actuating of relay, make the electromagnetic actuator coil charged on the one hand, make final controlling element action bleed, make the charged acoustooptic alarm signal that sends of audible-visual annunciator on the other hand.Working properly not the time when the needs detection device, only need press test button and get final product.
(3) technique effect
The utility model electromagnetic instrument tabular form pressurized container overvoltage protective device, substitute products as mechanical compression container overvoltage protective device, repertoire with former mechanical compression container overvoltage protective device, and has the not available performance of former mechanical compression container overvoltage protective device: possess self-checking function, can realize functions such as warning, shutdown; Can test at any time, in time adjust working value; Be convenient to equipment overhaul, verification, have practicability widely.
