Abstract
The utility model relates to a safety device, particularly a safety interlocking device for quick opening-typed pressure vessels. The utility model is characterized in that an electric magnet is arranged on a supporting plate, and a cylindrical pin is arranged under the electric magnet. The cylindrical pin is provided with a spring, one end of which acts on the supporting plate. The cylindrical pin is contacted with a concave pit on a limit ring through a guide hole on the supporting plate. The limit ring is sheathed on a door handle seat and is fixedly adjusted by an adjusting screw. The supporting plate is fixed on a front pressure plate connected with a door. An adjusting seat and a bracket are connected through bolts, and the other end of the bracket is fixedly connected to a door cover. A limit switch is fixedly connected to the adjusting seat, and the touch head of the limit switch is abutted on a door lever. The utility model achieves the requirements of the national labor department and has safety.
Description
The utility model relates to safety installations, is specially the safety interlock device of fast opening type pressure container that is used for the pressurized container aspect.
According to (1992) No. 9 gists of a document of national Department of Labor pot word: fast opening type pressure container is the key manufacturing mechanism that is widely used in industries such as chemical industry, light industry, weaving, building materials, medical and health, in 1980 to 1991 the pressurized container accidents, the fast opening type blast accounts for 1/3rd, therefore require the fast opening type pressure container of new production must possess safety interlock, existing fast opening type pressure container, should transform as early as possible, install safety interlock additional, that can't transform should do to scrap processing.
The purpose of this utility model is to provide a kind of fast opening type pressure container to avoid blast, safe and reliable safety interlock device of fast opening type pressure container.
The purpose of this utility model is achieved in that and is electromagnet on the supporting plate, under straight pin is arranged, spring is arranged on the straight pin, spring one end acts on the support plate, straight pin contacts with pit on the limited ring by the pilot hole on the support plate, limited ring is enclosed within on the door handle seat, by adjusting the screw adjustment, support plate is fixed on the front pressuring plate, and front pressuring plate links to each other with door, is connected by bolt and adjusts seat and support, the support the other end is fixed on the door closure, limit switch is fixed in to be adjusted on the seat, and the contact of limit switch withstands on the thick stick, automatic switch of electric leakage (LK) end serial connection air recloser (FA), block push button (SB
1), admission start button (SB
2), admission stop button (SB

Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment and working procedure are described in detail: be electromagnet on the supporting plate, under straight pin is arranged, spring is arranged on the straight pin, spring one end acts on the support plate, straight pin contacts with pit on the limited ring by the pilot hole on the support plate, limited ring is enclosed within, on the door handle seat, by adjusting the screw adjustment, support plate is fixed on the front pressuring plate, front pressuring plate links to each other with door, is connected by bolt and adjusts seat and support, and the support the other end is fixed on the door closure, limit switch is fixed in to be adjusted on the seat, the contact of limit switch withstands on the thick stick, automatic switch of electric leakage one end serial connection air recloser, block push button, the admission start button, the admission stop button, pressure gauge with electric contact, solenoid valve, electromagnet, throw over switch and auxiliary reclay, the other end and live wire, the neutral line joins.Push the earth leakage circuit-breaker test button, confirm its working properly after, just enter proper functioning.The rotary power source switch, tutorial light HL is bright, the door handle seat that turns clockwise, Dang Mengang depresses the limit switch contact, when cylindrical hole on the limited ring on the door handle seat is aimed at straight pin on the electromagnet, presses block push button SB
1, straight pin enters in the cylindrical hole of limited ring, and with the door closure locking, 1HL is bright for the interlocking tutorial light, by admission start button SB
2, connect solenoid valve, begin into steam in the device, 2HL is bright for the admission tutorial light, when starting of electric contact pressure list index and disengaging threshold pression position, rotary sampling switch SA
2To on positi, when reaching upper limit pressure, solenoid valve is closed, and air inlet stops, and 3HL is bright for upper limit pressure indicator light, and admission tutorial light 2HL goes out.By air inlet stop button SB
3, close solenoid valve, stop admission, admission tutorial light 2HL goes out.Before opening door closure, open bleed valve earlier, the steam in the tapping equipment, when pressure is reduced to threshold pression, the electromagnet outage, straight pin withdraws from the cylindrical hole of limited ring by spring, the door handle bracket is discharged, and 4HL is bright for the threshold pression tutorial light, and interlocking tutorial light 1HL goes out.Rotary power source switch S A again
2, for next operation is prepared.Inhour revolving door handle base after the door thick stick withdraws from from the device unthreaded hole, can be opened door closure.
