Background technique

In industries such as rubber, rock gas, food, extensive use fast opening type pressure container, sulfurizing pot are its typical representative equipment.Its essence is exactly that quick open device, easy-to-operat are installed on pressure vessel and equipment; Its critical piece is a quick-opening device, and what generally adopt is clip or moving-coil sealing.Open device has manually operated type, electrodynamic type, hydraulic type and pneumatic type fast.Electrodynamic type quick operating valve, the rotatable handle kink of its quick operating valve are on a leading screw slide block, and by driven by motor leading screw rotation, leading screw drives slide block and moves up and down, and close or screw out unlatching thereby the rotation of drive quick operating valve is bumped into.In practical operation, the operator is in confirming jar behind the no pressure, just presses button, and the discharging of opening the door if, might cause to be with to press off and open when pressure gauge is malfunctioning but air intake valve is not closed completely, causes the security incident generation; Perhaps there is people's malfunction to release the button at work, causes band to press off and open, cause security incident.

Summary of the invention

The purpose of this utility model provides the electronic quick operating valve safety interlocking of a kind of sulfurizing pot, to prevent in real work owing to operate miss or the malfunctioning security incident that causes of pressure gauge.

The utility model is realized by the following technical solutions: the electronic quick operating valve safety interlocking of a kind of sulfurizing pot, comprise handle, arm pivot post, handle is provided with axis hole, handle is installed on the arm pivot post by axis hole, handle can rotate in thorny handle rotating shaft, and the electronic quick operating valve safety interlocking of sulfurizing pot is provided with handle horizontal throw switch, handle vertical stroke switch, position limit switch support, pneumatic piston and handle self-locking device; Handle horizontal throw switch, handle vertical stroke switch are fixedly mounted on the position limit switch support, described handle self-locking device comprises self-locking initiatively pull bar, the driven pull bar of self-locking and stationary axle, the driven pull bar of self-locking is provided with axis hole and handle self-lock rod, driven pull bar of self-locking and handle self-lock rod are connected as a single entity, the driven pull bar of self-locking is assemblied on the stationary axle by axis hole, and the driven pull bar of self-locking can be the center rotation with the stationary axle under the pulling of self-locking active pull bar.

Can be provided with hanging hole on the driven pull bar of self-locking, the driven pull bar of self-locking hangs on the self-locking active pull bar by hanging hole.

Compared with prior art, the beneficial effects of the utility model are: the sulfurizing pot of the electronic quick operating valve safety interlocking of the utility model sulfurizing pot has been installed, can have been avoided effectively in actual mechanical process owing to operate miss or the malfunctioning security incident that causes of pressure gauge.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As scheming: 1, pneumatic piston; 2, handle self-lock rod; 3, handle vertical stroke switch; 4, handle; 5, arm pivot post; 6, handle horizontal throw switch; 7, stationary axle; 8, the driven pull bar of self-locking; 9, tank body support; 10, self-locking active pull bar; 11, hanging hole; 12, tank body; 13, leading screw; 14, slide block down journey switch; 15, slide block; 16, quick operating valve rotatable handle; 17, rotatable handle power lever; 18, support is opened in the quick operating valve load-bearing; 19, quick operating valve stationary axle; 20, slide block upper stroke switch; 21, end socket; 22, leading screw support; 23, motor; 24, position limit switch support.

The electronic quick operating valve safety interlocking of a kind of sulfurizing pot comprises handle 4, arm pivot post 5, and handle horizontal throw switch 6, handle vertical stroke switch 3, pneumatic piston 1 and handle self-locking device, handle 4 are provided with axis hole in order to be installed on the arm pivot post 5; Described handle self-locking device comprises self-locking initiatively pull bar 10, the driven pull bar 8 of self-locking and stationary axle 7, the driven pull bar 8 of self-locking is provided with handle self-lock rod 2 and axis hole, the driven pull bar 8 of self-locking is assemblied on the stationary axle 7 by axis hole, the driven pull bar 8 of self-locking is provided with hanging hole 11, the driven pull bar 8 of self-locking hangs on the self-locking active pull bar 10 by hanging hole 11, and the driven pull bar 8 of self-locking can be the center rotation with stationary axle 7 under the pulling of self-locking active pull bar 10.

When using the utility model, at first arm pivot post 5, stationary axle 7, position limit switch support 24 are fixed on the tank body 12 according to mutual position relation, self-locking active pull bar 10 is fixed on sliding fast 15, and then be installed in pneumatic piston 1 on the tank body 12 and the inner chamber of pneumatic piston 1 is communicated with the inner chamber of tank body 12, and when handle 4 was horizontal, pneumatic piston 1 was in the below of handle 4; Handle vertical stroke switch 3, handle horizontal throw switch 6 are pressed the electrical schematic diagram connection and are got final product.

The electronic quick operating valve safety interlocking of sulfurizing pot course of action is as follows:

1, close quick operating valve, quick operating valve rotatable handle 16 kinks are pressed X button on rotatable handle power lever 17, electric motor starting, and the quick operating valve rotation is bumped into closes, and rotates to when limiting the position, and the self-locking of handle 4 is removed in the motor stall simultaneously.

2, then handle 4 is raised up to level, depresses handle horizontal throw switch 6, disconnect quick operating valve and open circuit, simultaneously, tutorial light green light D1 is bright and report to the police connection electric valve circuit.At this moment, startup is released the button, and motor does not turn round, and quick operating valve can not be opened.

3, green light is bright, proves that safety interlocking has played protective action, simultaneously, because of connecting the electric valve circuit, i.e. can regulate electric valve aperture, equipment can normally pressurize.

4, in the tank body 12 in case pressurization is just crossed Pneumatic pipe cleaner conduit and is introduced pneumatic piston 1, the axle of pneumatic piston 1 is boosted, just in time withstand handle 4, handle 4 can not be depressed.

When 5, wanting to open quick operating valve, can only earlier electric valve be closed, the container pressure release, at this moment the axle of pneumatic piston 1 falls because of deadweight, and handle 4 could manually be depressed.When depressing handle 4, handle horizontal throw switch 6 resets, and connects quick operating valve and opens circuit; Depress handle vertical stroke switch 3 simultaneously, the bright and warning of tutorial light red light D2 disconnects the electric valve circuit simultaneously, and represent that quick operating valve allows to open this moment.

6, press quick operating valve and release the button, motor rotation, quick operating valve rotate to when limiting the position, and motor shuts down, and at this moment, can and open the quick operating valve rotation.
