Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Embodiment mono-:
As Figure 1-3, a kind of sampling port lid with locking device of the utility model comprises lid and locking device, lid comprises top board 7, base plate 11 and is connected to sidewall 1 between the two, top board 7 centers are provided with lock moving axis hole 9, on top board 7, be also provided with two register pins 12, sidewall 1 is provided with lockhole 10, and base plate 11 is tightly connected with sidewall 1; Locking device comprises switch plectrum 2, lock moving axis 3, lock Moving plate 4, connecting link 6, locking bar 5 and retaining washer 8, switch locking plate is positioned at top board 7 tops, the middle part of switch locking plate is fixedly connected with one end of lock moving axis 3, lock moving axis 3 penetrates in lid through lock moving axis hole 9, the below that lock moving axis 3 is positioned at top board 7 is provided with retaining washer 8, and the other end of lock moving axis 3 is fixedly connected with lock Moving plate 4; Lock Moving plate 4 and the vertical setting of lock moving axis 3, lock Moving plate 4 comprises at least two-layer, between adjacent two layers lock Moving plate 4, be fixedly connected with at least one coupling shaft, one end of locking bar 5 is provided with connecting hole, connecting link 6 is positioned at connecting hole, locking bar 5 is rotatably connected with connecting link 6, and the other end of locking bar 5 penetrates in lockhole 10; Locking bar 5 comprises the interlude of first paragraph, second segment and connection, first paragraph and second segment disalignment.
As shown in Figure 4, sampling port lid is arranged on thieff hatch 14, and the inwall of thieff hatch 14 is provided with annular groove 13, and after sampling port lid is installed, lockhole 10 aligns with annular groove 13 just.
The principle of work of a kind of sampling port lid with locking device of the utility model is as follows:
Sampling port lid is put into thieff hatch 14, rotating switch plectrum 2, switch plectrum 2 drives lock moving axis 3, lock Moving plate 4 to rotate together, the connecting link 6 at lock Moving plate 4 edges is also around the center rotating of locking Moving plate 4, be rotatably connected with connecting link 6 along with movement, the second segment that is positioned at lockhole 10 is by with stretching out to sidewall 1 together, and heads in the groove on thieff hatch 14 inwalls.When switch plectrum 2 is positioned pin 12 while blocking, locking finishes, and because second segment is positioned at groove, sampling port lid cannot be pulled out by external force.
During sampling, the switch plectrum 2 of oppositely walking around is to another register pin 12 places, and locking bar 5 is retracted in lockhole 10 under the drive of connecting link 6, between sampling port lid and thieff hatch 14, do not stop, and Drawing switch plectrum 2, the port lid of sampling just can be taken off like a cork.
Retaining washer 8 on lock moving axis 3 is close to the lower surface of top board 7, and the position of locking moving axis 3 in the time of can preventing taking-up sampling port lid changes, and avoids locking bar 5 and the position of lockhole 10 to produce skew, and assurance locking device is normally worked.On the other hand, retaining washer 8 can also play certain sealing function, and owing to having certain pressure reduction between the gas in thieff hatch 14 and the gas outside flue, retaining washer 8 can play certain barrier effect.
Locking bar 5 is arranged to three sections, and first paragraph is connected with connecting link 6, and second segment is positioned at lockhole 10, first paragraph and second segment disalignment, and connect by interlude; It is in order to reduce the anglec of rotation of locking bar 5 in locking and the process of unblanking that locking bar 5 is arranged like this, to keep the sealing effectiveness between locking bar 5 and lockhole 10 as far as possible, avoid the flue gas in thieff hatch 14 to enter in lid, the impurity corrosions such as steam that cause locking device to be carried in flue gas, prevent the phenomenon that locking device cannot be opened.
Switch locking plate limits its rotating range by two register pins 12, and while preventing from unblanking, rotation excessively causes the second segment of locking bar 5 and lockhole 10 to depart from, and causes locking device destroyed, to protect locking device.
Embodiment bis-:
The present embodiment and embodiment mono-are basic identical, and difference is: connecting link 6 is rotatably connected between Moving plate 4 with lock, between locking bar 5 and connecting link 6, are fixedly connected with.This structure also can head in annular groove 13 or retraction lockhole 10 by the locking bar 5 that rotarily drives of lock Moving plate 4, realizes locking and unlocking function.
As can be seen from the above embodiments, the utility model is by adopting the sampling port lid with locking device, and be provided with annular groove 13 on thieff hatch 14 inwalls, and realized and adopted the locking operation between port lid and thieff hatch 14, prevent that thieff hatch cover from departing from thieff hatch 14 under external force.Locking device is all arranged on lid portion inside; The first paragraph of locking bar 5 and second segment disalignment, guarantee the sealing effectiveness between locking bar 5 and shrinkage cavity, can effectively prevent that locking device is sampled the flue gas corrosion in hole 14, guarantee that locking device still can normally use in the situation that sampling port lid does not take off for a long time.Lock moving axis 3 is provided with retaining washer 8, can further prevent the air leakage phenomena of thieff hatch 14.
The Parallel Sampling hole that a kind of sampling port lid with locking device of the utility model is specially adapted on electricity power enterprise's boiler vertical gas pass is used, the utility model dropping of port lid that can prevent from sampling when equipment working condition from changing, realized the convenient and swift unlatching of flue thieff hatch 14, solve the problem that thieff hatch 14 is difficult to open, improved the work efficiency of fly-ash separator, the medium flue dust of sweetener performance test, flue gas sampling.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
