Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
A kind of pressure limiting valve control device as shown in Figure 1-2 comprises pressure limiting valve 6 and blast pipe 7, described pressure limiting valve 6 is arranged on the upper end of blast pipe 7 for controlling the opening and closing of blast pipe 7, also comprising man-operated mechanism, to be completed the exhaust condition of pressure limiting valve 6 for realizing user's hand away from pressure limiting valve 6 by described pressure limiting valve control device.
Described man-operated mechanism comprises tumbler 8, eccentric thrust unit 2 and push rod 5, described tumbler 8 is connected with eccentric thrust unit 2 can drive eccentric thrust unit 2 synchronous axial system, described eccentric thrust unit 2 matches with push rod 5 and push rod 5 can be driven to seesaw, and described push rod 5 can drive described pressure limiting valve 6 to open or close.
Preferably, described eccentric thrust unit 2 is eccentric cam.Described tumbler 8 is connected on lid by bearing seal is rotating, the lower end of described tumbler 8 is fixedly connected with eccentric thrust unit 2, described push rod 5 one end and described eccentric thrust unit 2 abut against, the other end has jack-up end, described jack-up end matches with the spool of described pressure limiting valve 6, and when push rod 5 seesaws, band movable valve plug is opened or is closed blast pipe 7.
Pressure limiting valve 6 is opened instead by tumbler 8 rotating opening pressure limiting valve 6 by using lever construction in prior art, operate more convenient, more laborsaving, simultaneously under the effect of push rod 5 and eccentric thrust unit 2, the distance of staff and pressure limiting valve 6 is increased greatly, enhances the security of operator.
Described eccentric thrust unit 2 moves to the right for intermittent promotion push rod 5.When tumbler 8 drives eccentric cam to rotate, it promotes push rod 5 and moves right, and the jack-up of described push rod 5 is held the switch jack-up of pressure limiting valve 6, after exhaust terminates, tumbler 8 is not under being subject to External Force Acting, and the eccentric cam of its lower end transfers back to the initial state that do not stress.
Described push rod 5 is positioned at the below of valve switch, and the right-hand member of described push rod 5 is jack-up end, and the height of described jack-up end is height reduction from left to right.Preferably, described jack-up end is cone or Rotary-table.After described jack-up end receives push rod 5 thrust from left to right, move right, jack-up end is more and more higher with the height of the contact point of valve switch, until jack-up end is by complete for valve switch jack-up, to start exhaust.
As the preferred version of the technical program, described push rod 5 is also arranged with back-moving spring 3, described push rod 5 is also installed with holding flange, one end of described back-moving spring 3 is pressed on holding flange, and the other end is pressed on limited block 4.Wherein, holding flange moves with push rod 5, and limited block 4 is actionless relative to push rod 5.Therefore, when push rod 5 moves right, the left end of described holding flange pressed home spring 3 promotes to the right, and the inner side of limited block 4 receives the pressure of back-moving spring 3 simultaneously.
Described limited block 4 is fixed on the inside of device, described limited block 4 is provided with the spacing hole of allowing that push rod 5 freely penetrates.The aperture of described spacing hole is greater than the diameter of push rod 5, is less than the diameter of back-moving spring 3.Push rod 5 can freely be come in and gone out spacing hole.
When push rod 5 promotes to the right, back-moving spring 3 is subject to the extruding of holding flange and limited block 4, when push rod 5 completes exhaust, when the thrust that it is subject to disappears, back-moving spring 3 promotes holding flange relative to limited block 4 and is moved to the left, and finally, reaches the nature do not stressed.
In order to the convenience of user's operation, the upper end of described tumbler 8 is fixedly connected with jug 1.
Additionally provide a kind of electric pressure cooking saucepan, have described pressure limiting valve control device, described pressure limiting valve control device is arranged on pot cover.Described limited block 4 is fixed in electric pressure cooking saucepan.
In sum, by the pressure limiting valve control device be made up of tumbler, eccentric thrust unit, push rod, make, in exhaust process, there is between hand and pressure limiting valve safe distance, eccentric thrust unit is under the drive of tumbler simultaneously, repeatedly can open pressure limiting valve to be easily exhausted, and the performance of exhaust can be checked easily; In addition back-moving spring and limited block be arranged so that exhaust conductance mechanism can automatically reset after exhaust, play sealing effectiveness.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
