Abstract

The utility model relates to a pressure displaying device which used by matching with a lid opening and closing safety mechanism of a pressure cooker. The utility model is composed of a display valve body installed on a hand lever, a valve cylinder installed in the display valve body, a display rod arranged in the valve cylinder and a spring sheathed on the display rod, wherein, scale marks are arranged on the surface of the upper part of the display rod, wherein, the lower end of which is contacted with an opening stopping valve core in an opening stopping valve. When the inner of the cooker has pressure, the opening stopping valve core can jack up the display rod which is made to move upwards, and higher the display rod moves upwards, larger the pressure is. Thereby, the utility model is used by matching with the lid opening and closing safety mechanism and has the advantages of convenient operation, high safety, etc.

Description

The pressure cooker pressure-display device

The utility model belongs to pressure cooker auxiliary security operative installations, particularly the pressure-display device that is used with the pressure cooker open and close cover release mechanism.

For fear of cause contingency because of the pressure cooker lid folding is improper, the applicant had once applied on May 28th, 1998 and on October 29th, 1999 that the patent No. was respectively two kinds of pressure cooker open and close cover safeties patents of 98214955.7 and 992515831.They are provided with a self-locking mechanism on the usual pressure pot handle, when pot cover covers when not in place, pot inner pressure can not raise; When in the pot pressure being arranged, pot cover can not be opened; Thereby guaranteed the pressure cooker open and close process safe.But do not show the pot inner pressure state in such safeties, this makes troubles to the user, and violation operation takes place easily, causes parts damages, influences the service life and the service behaviour of folding lid safeties.

The purpose of the utility model is to provide a kind of and is used with pressure cooker open and close cover insurance institution, can show the corollary apparatus of pot inner pressure situation.

The technical solution of the utility model is such: it is equipped with the demonstration valve body on the handle that has pressure cooker open and close cover insurance institution, on the stopping valve position valve cylinder is housed relatively in showing valve body, and valve cylinder is built-in with display pole, is with spring on the display pole.One end of spring be against shoulder in the middle of the display pole protruding on, the other end withstands on the valve cylinder port.The display pole upper face has the pressure scale line, and touch mutually with stopping valve core in the stopping valve lower end.When in the pot pressure being arranged, move on the stopping valve core, and the rising of jack-up display pole, display pole rises high more, and expression pressure is big more, and the scale on it is represented the pressure in the pot.Simultaneously, as long as in the pot air pressure is arranged, the stopping valve core stops pot cover to be opened by folding lid insurance institution.

In order to make display pole can show a pressure in the pot sensitive, exactly, the stopping valve in the pressure cooker open and close cover insurance institution is done corresponding the improvement, promptly stopping valve by valve seat and be applied on the valve seat through hole, the stopping valve core of slippage up and down forms.Stopping valve core and the valve seat rigidity is close joins, its outside, top is embedded with the O RunddichtringO of the spacing usefulness of double as.

Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Referring to Fig. 1, the pressure cooker pressure-display device is embedded in valve cylinder 6 that shows in the valve body 3 and the spring 8 that places the display pole 7 in the valve cylinder 6 and be enclosed within on the display pole 7 and is formed by the demonstration valve body 3 that is stuck on the upper handle 1.

Valve cylinder 6 is relative with stopping valve, and its upper port is made thin mouthful, and bore is slightly larger than display pole 7 diameters; One end of spring 8 withstands on the thin mouthful limit of valve cylinder 6, the other end be against shoulder in the middle of the display pole 7 protruding on; Display pole 7 bottoms are made thin bar and are passed upper handle 1 and touch mutually with stopping valve core 10.Display pole 7 upper faces have the pressure scale line, and display pole 7 rises high more, and the expression pot inner pressure is big more.

Stopping valve core 10 is the parts of a brake handle folding in the pressure cooker open and close cover insurance institution, and it and valve seat constitute stopping valve.Valve seat 4 usefulness nuts 5 and pad 11 are fixed on the pot cover 12, and stopping valve core 10 is applied in the valve seat 4 and the upper and lower slippage of rigidity thereon, and its gap is less than 0.3mm; The outside, stopping valve core 10 tops is embedded with O RunddichtringO 9, and it had both prevented that stopping valve core 10 from gliding, again seal valve seat 4 ports.

After pressure cooker covered, when in the pot pressure being arranged, pressure promoted to move on the stopping valve core 10, and at this moment, stopping valve core 10 jack-up display pole 7 on the one hand rises, and it is high more to rise, and pot inner pressure is just big more, and the pressure that graduation mark is represented is also big more.Stop moving of slide block in the folding lid insurance institution on the other hand again, pot cover 12 can not be opened.

Obviously, when the utility model tool and folding lid release mechanism is used, safer can Lean on, more convenient operation, have simple in structure, good looking appearance, the advantage such as security is good. Be suitable for assembling On the pressure cooker of handle with folding safety device.

Claims
