CN202012241U - Reaction vessel door lock - Google Patents

Abstract

The utility model refers to a reaction vessel door lock, comprising a lock casing, a lock bar, a slide bar spring, an electromagnet, a slide bar and an electric contact pressure gauge; the lock casing comprises a through lock bar channel and a slide bar channel perpendicular with the lock bar channel, and the slide bar channel is communicated with the lock bar channel; the lock bar is provided with a positioning slot and the lock bar on one side of the positioning slot is provided with a baffle plate; the slide bar is in sliding cooperation with the slide bar channel and is in cooperation with the positioning slot on the lock bar; the upper end of the slide bar is in connection with the electromagnet through the slide bar spring, and the electric contact pressure gauge is in connection with the electromagnet. With the above structure, the lock bar is inserted in to a positioning hole of a reaction vessel, when the inner of the reaction vessel has pressure, the electric contact pressure gauge is in a normal switch state and the slide bar is locked with the lock bar so that one can not separate the lock bar from the positioning hole of the reaction vessel; when the inner of the reaction vessel has no pressure, the electric contact pressure gauge is in a closed state, and the electromagnet is electrified, the slide bar is separated from the lock bar, and meanwhile the lock bar can be departed from the positioning hole so that the reaction vessel can be opened. The reaction vessel door lock can eliminate potential safety hazard.

Description

A kind of reactor door lock

Technical field

The utility model relates to a kind of lockset, especially a kind of door lock that is used for the still door of reactor.

Background technology

Present prior art, the reactor door no matter have or not pressure in the still, all can be opened the still door.There is potential safety hazard.

Summary of the invention

The purpose of this utility model is: a kind of reactor door lock is provided, and it can make the still door open under the situation of fully pressure-free power, has eliminated potential safety hazard.

The utility model is achieved in that a kind of reactor door lock, comprises lock housing, locking bar, slide bar spring, electromagnet, slide bar and electro connecting pressure gauge;

Described lock housing comprise perforation the locking bar passage and with the slide bar passage of locking bar channel vertical, slide bar passage and locking bar channel connection;

Have on the locking bar on the locking bar of locating slot, locating slot one side baffle plate is arranged;

Slide bar and slide bar passage are slidingly matched, and slide bar cooperates with locating slot on the locking bar, and the upper end of slide bar is connected with electromagnet by a slide bar spring, and electro connecting pressure gauge is electrically connected with electromagnet.

A kind of reactor door lock of the utility model, owing to adopt such structure, locking bar inserts the locating hole of still door, and when in the still pressure being arranged, electro connecting pressure gauge is in normal on off state, and slide bar and locking bar are sealed, and people can not make locking bar separate with the locating hole of still door; When in the still during no pressure, electro connecting pressure gauge is in closure state, the electromagnet energising, and slide bar separates with locking bar, at this moment, can make locking bar leave locating hole, thereby beat the still door; Eliminated potential safety hazard.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1 and Figure 2, a kind of reactor door lock comprises lock housing 1, locking bar 2, slide bar spring 3, electromagnet 4, slide bar 5 and electro connecting pressure gauge 6;

Described lock housing 1 comprise perforation locking bar passage 11 and with the slide bar passage 12 of locking bar channel vertical, slide bar passage 11 is communicated with locking bar passage 12;

Have on the locking bar 2 on the locking bar of locating slot 21, locating slot 21 1 sides baffle plate 22 is arranged;

Slide bar 5 is slidingly matched with slide bar passage 12, and slide bar 5 cooperates with locating slot 21 on the locking bar 2, and the upper end of slide bar 5 is passed through a slide bar spring 3 and is connected with electromagnet 4, and electro connecting pressure gauge 6 is electrically connected with electromagnet 4.

Above-described only is preferential embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
