Abstract

The utility model discloses a safety interlocking device for a quick opening blind plate. An alarming threaded rod and a safety lock are fixedly integrated. A piston chamber is communicated with a pressure container. When pressure exists in the piston chamber, a piston rod moves in the piston chamber under the action of the pressure to further drive a sleeve and a sleeve sealing head, which are connected with the piston rod, to block an insertion opening of the alarming threaded rod and disable an operator to insert a stress application rod into the insertion opening to rotate the alarming threaded rod to prompt the operator that the quick opening blind plate cannot be operate, so that the safety is improved. Moreover, the device is simple in structure and convenient to mount.

Description

A kind of safety interlock of fast-opening blind
Technical field
The utility model relates to a kind of safety interlock of fast-opening blind, belongs to fast-opening blind pressure vessel technology field.
Background technique
Fast-opening blind is widely used on container or equipment, filter separator in gas gathering station, the receiving ball tube of long distance pipeline etc., convenient production and operation in the normal process of using, yet improper use or operate and will have potential safety hazard not according to working specification, if when operator open the fast-opening blind of filter separator, the pressure in filter separator is not discharged completely, under the effect of pressure, fast-opening blind throws open, and has serious potential safety hazard; Sometimes, when operator close fast-opening blind, when blind plate is not closed completely, pressurized container just starts booste operation, causes pressurized container to be blasted, and threatens operator to state safety.The safety interlock of fast-opening blind, can stop the generation of similar accident completely, when pressure discharges completely, safety interlock can be opened fast-opening blind after throwing off, and alarm screw and safety lock have been installed on fast-opening blind, while having overbottom pressure in container, the lock core of safety lock can stop operator to take out alarm screw, thereby indirectly stops operator to open door closure, and Accident prevention occurs.But at the safety lock that present stage is used, making and installing comparatively complexity, Long-Term Properties is unstable, and the normal operation of equipment and operator's safety reliability are brought to hidden danger.
Model utility content
The purpose of this utility model is for the deficiencies in the prior art, proposes a kind ofly can bear high pressure and simple in structure, fast-opening blind safety interlock easy for installation.
The utility model is that the adopted technological scheme that achieves the above object is:
A safety interlock for fast-opening blind, comprises alarm screw, safety lock, and end cap, piston cavity and interior piston rod thereof, sleeve and with it fixing sleeve end socket, described alarm screw and safety lock are fixed; Described piston cavity is connected with the pressurized container in fast-opening blind by pipeline; Described piston cavity is placed in end caps, and piston rod is through end cap, and the end of described piston rod and sleeve end socket are connected and fixed.
Aforesaid alarm screw joint adopts O type circle one and the sealing of bullet pad.
The port of aforementioned piston cavity is provided with O type circle two.
Compared to the prior art, the utlity model has following beneficial effect: alarm screw and safety lock are united two into one, simple in structure, easy for installation, the safety problem having occurred while effectively having avoided operation fast-opening blind, guaranteed that production process is medium-altitude safe and reliable, reduced operator's danger.
Accompanying drawing explanation
Fig. 1 is the safety interlock structural representation of the utility model fast-opening blind.
Embodiment
Now by reference to the accompanying drawings and embodiment, the utility model is further elaborated.
As shown in Figure 1, the safety interlock of fast-opening blind of the present utility model comprises alarm screw 1, safety lock 4, end cap 8, piston cavity 5 and interior piston rod 6 thereof, sleeve 9 and with it fixing sleeve end socket 10, wherein alarm screw 1 is fixing with safety lock 4, the joint of alarm screw 1 adopts O type circle 1 and 3 sealings of bullet pad, piston cavity 5 is placed in end cap 8 places, and piston rod 6 is through end cap 8, and the port of piston cavity 5 is provided with O type circle 27, in order to improve the sealing of piston cavity, the end of piston rod 6 and sleeve end socket 10 are connected and fixed.
During use, while having pressure in fast-opening blind inner pressure vessel, pressure enters in piston cavity by pipeline, and piston rod is ejected under the effect of pressure, drives the sleeve end socket and the sleeve that are attached thereto to be ejected, now, alarm screw injects mouth and is blocked by the sleeve, and operator cannot inject extension lever socket turn alarm screw, and fast-opening blind can not be opened, remind operator's device interior to have pressure, can not operate.
In fast-opening blind inner pressure vessel, during without pressure, piston rod returning position is with moving sleeve end socket and sleeve to get back to origin-location simultaneously, and now operator inject socket by extension lever, can screw out alarm screw, can open fast-opening blind like this.
Above embodiment has described the utility model in detail; but person skilled is not within departing from the scope of the utility model technological thought; the change of carrying out and modification, all belong to protection domain of the present utility model, and the utility model is determined its protection domain according to claim scope.

Claims (3)
