Description
Technical field:
The utility model belongs to pressure vessel of quick opening door safety interlocking control technique field.
Background technique:
Pressurized container often is horizontal type structure, housing is provided with material feeding mouth and discharge port, the material feeding mouth operated by rotary motion is on the top of housing, discharge port is arranged on lower part of frame one end, on material feeding mouth and discharge port, all be installed with quick operating valve, open quick operating valve during discharging, when work, need utilize quick operating valve that material feeding mouth and discharge port sealing is tight.According to the requirement of pressure vessel safety regulation, on quick operating valve, also safety interlock should be set, make that people can not open quick operating valve, have only after pressure discharges fully, just can open quick operating valve when in the pressurized container pressure being arranged; On the other hand, have only quick operating valve shut after, the work of just boosting.Present mechanical type quick operating valve interlock, mainly constitute by actuator and control box, actuator comprises: electromagnet, spring, pin, snubber, electromagnetic valve, control box comprises: auxiliary reclay, electric contact point pressure gauge, tutorial light, button, main rely on electromagnet to the adhesive of pin and spring to the tractive of pin, finish interlocking to safety door.This interlock is applicable to the situation that the quick operating valve diameter is less, and pin needs vertical the installation, for the pressurized container of quick operating valve diameter greater than φ 800, then less because of electromagnet suction, pin can not strengthen, and its shearing force is less, sometimes because of vibration equipment, also malfunction can take place, therefore can not satisfy demand for security fully.
The model utility content:
It is solid and reliable that the purpose of this utility model provides a kind of interlocking, is not afraid of the pneumatic safety interlock of pressure vessel of quick opening door of vibration equipment.
To achieve these goals, the utility model comprises: electric appliance control box, air compressor, actuator, electric contact point pressure gauge, electromagnetic valve, auxiliary reclay is installed on the electric appliance control box, solenoid directional control valve, tutorial light, button, electric contact point pressure gauge and electromagnetic valve are fixedly mounted on the top of pressurized container, quick-opening device is on discharge port and material feeding mouth, quick operating valve is made up of a cover and a jar mouthful flange, utilize lead with electric appliance control box, air compressor, actuator, electric contact point pressure gauge, electromagnetic valve is connected with each other, actuator is arranged on the quick operating valve, actuator is by housing, cylinder, bearing pin, snubber constitutes, adopt pressure tube to be connected between air compressor and the cylinder, snubber, cylinder, bearing pin is arranged on the inside of housing, bearing pin is connected the bottom of cylinder and is driven by cylinder, the lower end of bearing pin can be inserted in the groove on the cover by jar mouth flange, and position limiter device is in bearing pin one side and by the bearing pin control action.
Like this, when in the pressurized container during no pressure, electric contact point pressure gauge is in zero-bit, presses door open button, solenoid directional control valve moves right, air compressor is started working simultaneously, and pressurized gas is sent into cylinder, and cylinder drives bearing pin and extracts, bearing pin drives snubber work simultaneously, green tutorial light is luminous, and the expression bearing pin is extracted, and can open the door.Need at closing time, door is closed put in place, can press X button, selector valve is moved to the left, air compressor is started working simultaneously, and pressurized gas is sent into cylinder, drives bearing pin and stretches out, in the insertion groove, locking quick operating valve, bearing pin drive snubber work simultaneously, and red tutorial light is luminous, the expression door is locking, can boost.The utlity model has easy to operately, it is solid and reliable to interlock, and is not afraid of vibration equipment and causes characteristics such as misoperation.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is quick operating valve and actuator's assembly structure schematic representation.
Embodiment:
