Abstract
The utility model provides a pressure-reducing valve with timing control device which is suitable to be arranged on the pipeline of a liquefied gas stove. The pressure-reducing valve with a timing control device is improved on the basis of the existing pressure reducing valves. The pressure-reducing valve with the timing control device is mainly characterized in that the timing control devices composed of timers, levers, elastic diaphragms, valve cores, compression springs and support plates are arranged in a pressure reducing chamber and at the upper part of a valve body to make the pressure-reducing valve can automatically cut off a power supply at a set time. Therefore, the pressure-reducing valve with the timing control device has the function of the timing control. The utility model has the advantages of compact structure, convenient operation and safety.
Description
The utility model relates to a kind of reduction valve, particularly a kind of reduction valve that has timing control apparatus on the pipeline that is contained in household liquified steam stove that is applicable to.
As everyone knows, reduction valve is one of device of household liquified stove indispensability, in order to the pressure and the flow of control liquid gas, makes liquefied gas furnace energy normal combustion.But, used reduction valve all is not provided with timing control apparatus at present, this not the exempt from customs examination user bring some troubles, if the user wants to order with boiling than the long time, but catching up with working again or do other thing and can not go back to close stove, naturally produce contradiction, this thing happens occasionally in people's life.
The purpose of this utility model is to overcome the existing existing problem of reduction valve, and a kind of reduction valve that has timing control apparatus is provided.
Below in conjunction with accompanying drawing the utility model is carried out detailed narration.
Fig. 1 is a section of structure of the present utility model.
As shown in drawings, the utility model is by air inlet pipe (16) existing, decompressor (17), valve body (2), improve on the pressure-reducing valve that pressure-reducing chamber (1) and escape pipe (4) form and form, its improvements are: the valve body of (1) (2) is installed a support plate (3) in the pressure-reducing chamber, put a compression spring (5) at support plate (3), a spool (6) places on the compression spring (5) with its shaft shoulder, the through hole (13) that pressure-reducing chamber (1) upper wall is passed on the top of spool (6) contacts with a slice flexible sheet (8), flexible sheet (8) is fixed on the valve body (2) by a hollow pressing plate (9) that links with valve body (2), load onto a lever (10) at hollow pressing plate (9), one end of lever (10) contacts with the flexible sheet (8) of spool (6) position, top, the other end contacts with the contact (15) of the timer (11) that is installed in valve body (2) top, on spool (6) and the shaft shoulder that pressure-reducing chamber (1) upper wall contacts, a sealing ring (7) is housed also, has the venthole (12) that communicates with escape pipe (4) at pressure-reducing chamber (1) upper wall that sealing ring (7) seals. For the sealing effectiveness of enhanced leaktightness circle (7), (1) corresponding upper wall also arranges a sealing bulge loop (14) in the pressure-reducing chamber. Spool (6) can be made of plastic. Also be provided with a valve gap (18) that is connected with timer (11) adjusting knob, makes with ABS plastic at the top of valve body (2).
Operation principle of the present utility model is such: in the working time that people set, the contact (15) of timer (11) just presses down, by lever (10) and flexible sheet (8) spool (6) is pushed, liquid gas through decompression just can enter escape pipe (4) by venthole (12), for the stove burning. When timer (11) is finished the time that people set, its contact (15) rises, compression spring (5) just jack-up spool (6) is pressed on sealing ring (7) on the sealing bulge loop (14), sealed venthole (12), cut off the gas of stove and supply with, thereby reached the requirement that timing controlled is stopped working automatically.
During use, people are as long as turn valve gap (18) transfers to the desired control time with timer (11), and stove just can extinguish at preset time.
The utlity model has the timing controlled function, easy to use, safe, and compact structure, be applicable on the pipeline that is contained in household liquified steam stove.
Claims (5)
1, a kind of by suction tude (16), decompressor (17), valve body (2), the reduction valve that underpressure chamber (1) and steam outlet pipe (4) are formed, it is characterized in that the last support plate (3) of installing of valve body (2) in underpressure chamber (1), on support plate (3), put a pressure spring (5), a spool (6) places on the pressure spring (5) by its shaft shoulder, the through hole (13) that underpressure chamber (1) upper wall is passed on the top of spool (6) contacts with a slice flexible sheet (8), flexible sheet (8) is fixed on the valve body (2) by a hollow pressing plate (9) that links with valve body (2), on hollow pressing plate (9), load onto a lever (10), one end of lever (10) contacts with the flexible sheet (8) of spool (6) position, top, the other end contacts with the contact (15) of the timer (11) that is installed in valve body (2) top, on spool (6) and the shaft shoulder that underpressure chamber (1) upper wall contacts a seal ring (7) is housed also, the upper wall in the underpressure chamber (1) that seal ring (7) is sealed has air outlet hole (12).
2, reduction valve according to claim 1 is characterized in that also being provided with a sealing bulge loop (14) at underpressure chamber (1) upper wall that seal ring (7) is contacted.
3, reduction valve according to claim 1 is characterized in that also being provided with at the top of valve body (2) valve gap (18) that is connected with the knob of timer (11).
4, reduction valve according to claim 1 is characterized in that spool (6) is made of plastic.
5, reduction valve according to claim 3 is characterized in that valve gap (18) is to make with ABS plastic.
