Abstract
The utility model discloses a quick opened safety interlocking device arranged on a quick opened door pressure container. An entire cavity comprises an upper cavity and a lower cavity, a membrane positioned between the upper cavity and a lower cavity, an upper clip cover and a lower clip cover both connected with the membrane, an expandable lock rod through the lower clip cover arranged on the upper clip cover, and a spring arranged on the lower clip cover and coiled on the lock rod. The utility model has the advantages of simple structure, compaction, and good safety performance; besides, the lock rod can not retract because of the tiny pressure of the internal part, and then an alarm screw bolt can not be taken off in safety so that the quick opened door can not be opened while the small hole of the alarm screw bolt can make the alarming sound of the air outlet, and the alarming sound can remind the operator of the internal pressure so that doubly protecting the safe operation of the quick opened door.
Description
Technical field
The utility model relates to a kind of additional device of door-opening pressure vessel, especially a kind of safety interlocking of door-opening pressure vessel.
Background technique
The safety interlocking that door-opening pressure vessel of the prior art adopts utilizes electrometric sensor usually, and it installs more complicated.And the door-opening pressure vessel Environmental Conditions is relatively more abominable usually, temperature, humidity change greatly, therefore belt sensor etc. is installed, operation is very inconvenient, react insensitive and can not bearing certain pressure, and the safety reliability that the normal operation and the operator of equipment operate is brought hidden danger.
The model utility content
The purpose of this utility model is the above-mentioned deficiency at prior art, propose a kind of can bear high pressure, easy for installation, be quick on the draw and not affected by environment and door-opening pressure vessel on the quick operating valve safety interlocking that is used of special-purpose warning bolt.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions: a kind of quick operating valve safety interlocking, be installed on the door-opening pressure vessel, and constituted whole cavity by upper cavity and lower chamber, comprising: the diaphragm between upper cavity and lower chamber; Upper cover that links to each other with diaphragm and following folder lid; Pass down the folder lid, be located at telescopic locking bar on the upper cover; Be installed in down that folder covers, the spring on the locking bar.
Compare with prior art; the utlity model has following beneficial effect: the utility model is simple in structure, compact; Safety performance is good, and there is slight pressure inside, and locking bar just can not withdrawn; the warning bolt just can not be removed fully; quick operating valve is not just opened, and the warning aperture on the bolt of reporting to the police simultaneously can send the gas song, reminds the operator that inner band is pressed; duplicate protection has like this ensured the operating security of quick operating valve.
Description of drawings
Fig. 1 is the structural representation of door-opening pressure vessel.
Fig. 2 is the structural representation of quick operating valve safety interlocking.
Wherein, 1 is door-opening pressure vessel; 2 are the warning bolt; 3 is the quick operating valve safety interlocking; 4 is mounting plate; 5 is pressure inlet tube; 31 is lower chamber; 32 is upper cover; 33 for pressing from both sides lid down; 34 is diaphragm; 35 is spring; 36 is locking bar; 37 is upper cavity; 38 is axle sleeve; 39 is O type circle.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, warning bolt 2, safety interlocking 3, mounting plate 4 and pressure inlet tube 5 are installed on the door-opening pressure vessel 1.
As shown in Figure 2, quick operating valve safety interlocking 3 has constituted whole cavity by upper cavity 37 and lower chamber 31, comprising: the diaphragm 34 between upper cavity 37 and lower chamber 31; The upper cover 32 that links to each other with diaphragm 34 covers 33 with following folder; Passing down folder covers 33, is located at telescopic locking bar 36 on the upper cover 32; Be installed in down that folder covers on 33, the spring 35 on the locking bar 36.In addition, also include the axle sleeve 38 that is set on the locking bar 36.Sealed with O type circle 39 between lower chamber 31 and the upper cavity 37.
During use, when there is pressure door-opening pressure vessel 1 inside, pressure is transported in the cavity of quick operating valve safety interlocking 3 by the pressure inlet tube 5 of door-opening pressure vessel 1, act on and produce motion on the diaphragm 34 between the upper and lower cavity 37,31, pass to down folder and cover 33 and spring 35, spring 35 compressions, promote locking bar 36 and in axle sleeve 38, stretch out certain-length, withstand on the screw rod of warning bolt 2, make its nut not to be removed, the clip of door-opening pressure vessel 1 can not 180 ° of directions move, and whole door-opening pressure vessel 1 is not just opened.Even the nut on the at this moment loosening warning bolt 2, the aperture on the warning bolt 2 also can send the gas whistle, reminds operator's device interior that pressure is arranged, and is not with press operation.
When the no pressure in door-opening pressure vessel 1 inside, diaphragm 34 returning positions, spring 35 loosens, locking bar 36 withdrawals, 2 stop of warning bolt are removed, thereby pull down 180 ° of direction displacements of clip that its nut can make door-opening pressure vessel 1, can be easy to open door-opening pressure vessel 1 like this.
The utility model is simple in structure, and is easy to install, utilizes door-opening pressure vessel interior media pressure as power, is quick on the draw, stable and reliable for performance, and can be used in the higher occasion of pressure in the door-opening pressure vessel.
Claims (3)
1, a kind of quick operating valve safety interlocking is installed on the door-opening pressure vessel, it is characterized in that: constituted whole cavity by upper cavity and lower chamber, having comprised: the diaphragm between upper cavity and lower chamber; Upper cover that links to each other with diaphragm and following folder lid; Pass down the folder lid, be located at telescopic locking bar on the upper cover; Be installed in down that folder covers, the spring on the locking bar.
2, quick operating valve safety interlocking according to claim 1 is characterized in that: also include the axle sleeve that is set on the locking bar.
