Abstract
The utility model relates to a multifunctional safety valve for household pipeline fuel gas. The utility model is mainly composed of a timing closing mechanism, a safety protecting device and an energy-saving magnetizing device. The utility model is characterized in that a conical spring (11) is sheathed on a shutter assembly (12); one end of the shutter assembly (12) is abutted on an isolation diaphragm (6), and the other end of the shutter assembly (12) is butted with the bottom of the conical spring (11). The top of the conical spring (11) is butted with a shutter pressing plate (10). A small ball (18) is arranged on a current limiting and regulating screw rod (16). A reset switch (19) is arranged relative to the small ball (18), and a ball sealing (17) is clamped in a gas passage on the right side of the small ball (18). The utility model has the functions of limiting current, automatic cutting off gas source, and switching off the gas source in definite time, and has the advantages of high safety, energy saving, etc.
Description
The utility model is a kind of home pipeline combustion gas multifunctional safety valve, particularly a kind of multifunctional fuel safety valve that relates to piped gas, rock gas, stone oil gas etc.
At present, cock-type or general cut-off type valve switch are all adopted in domestic piped gas, natural gas, stone oil gas etc.This class switch is along with the lengthening of service time, valve in various degree exist gas leak phenomenon.The user who has does not in addition note closing stop valve at ordinary times, only depend on to close the stove and accessory valve and reach the cut-out source of the gas, like this from the valve to the cooking stove between because of connecting with sebific duct, whether the sebific duct interface tight, whether sebific duct has damaging small sand holes etc., can cause becoming flat.Particularly, easily produce bigger harm when sebific duct comes off, when cracking or breaking out of fire, can not cut off source of the gas automatically.Also have some user when heating up water, to leave the kitchen,,, fail in time to find, and cause the phenomenon of CO poisoning and fire accident also to happen occasionally also because of not cutting off source of the gas automatically when water is boiled when stove being put out by water after overflowing.
The purpose of this utility model is to provide a kind of home pipeline combustion gas multifunctional safety valve.So that it have current limliting, automatically cut off source of the gas, regularly close the function of source of the gas, also have advantages such as safe and reliable and energy-conservation simultaneously, to overcome above-mentioned deficiency.
The purpose of this utility model is achieved in that it mainly is made up of timing closing mechanism device, safety protection device and magnetization energy-saving device three parts, it is characterized in that: they are installed on the same air flue successively, and the magnetization energy-saving device is made up of two blocks of magnet (23) and middle springs (20), is installed on the suction port of safety valve; Safety protection device is installed in the middle of the air flue, regulates screw mandrel (16) by current limliting and is screwed on the pneumatic duct, the inner ball (18) of placing, and its opposite position is provided with reset switch (19), and ball sealing (17) is stuck in the air flue of ball (18) right side; Regularly closing mechanism device is installed on the air flue of air outlet one side, the break-make of air flue, by valve combination (12) control, one end and isolation diaphragm (6) near, the other end puts tower spring (11) back and valve pressing plate (10) is abutted against; Isolation diaphragm (6) cooperates with timer (5) and is abutted against; The control of duration of ventilation is set (timer is existing parts) by the knob (1) on the timer indicator panel (2).When knob (1) open mode, isolate diaphragm (6) jack-up valve combination (12) and open air flue; Isolate the effect of diaphragm (6) owing to tower spring (11) when knob (1) turn-offs, source of the gas is turn-offed in valve combination (12); Reach the control of duration of ventilation like this.
The utlity model has current limliting, automatically cut off source of the gas, regularly close the function of source of the gas, so its can energy saving, reduce harm, be a kind of ideal, safe and reliable home pipeline combustion gas multifunctional safety valve.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is an overall structure schematic representation of the present utility model.
Accompanying drawing 2 is structural representations of the utility model safety protection device part.
Accompanying drawing 3 is modular construction schematic representation of the utility model valve combination 12.
Wherein: 1, knob 2, timer indicator panel 3, plus screw 4, valve body 5, timer 6, isolation diaphragm 7, seal membrane 8, lid 9, plus screw 10, valve pressing plate 11, tower spring 12, valve combination 13, air chamber 14, plus screw 15, O type circle 16, current limliting is regulated screw mandrel 17, ball sealing 18, ball 19, reset switch 20, spring 21, valve cast 22, rubber pad 23, magnet.
As Fig. 1, Fig. 2, shown in: it mainly is made up of the utility model timing closing mechanism device, safety protection device and magnetization energy-saving device three parts; it is characterized in that: they are installed on the same air flue successively; and the magnetization energy-saving device is made up of two blocks of magnet (23) and middle springs (20); be installed on the suction port of safety valve; like this when inflammable gas passes through the suction port of safety valve; can make the combustion gas micel intensify the back division; in burning with oxygen mixed combustion more fully, thereby reach purpose of energy saving.Safety protection device is installed in the middle of the air flue; regulating screw mandrel (16) by current limliting is screwed on the pneumatic duct; the inner ball (18) of placing; its opposite position is provided with reset switch (19); ball sealing (17) is stuck in the air flue of ball (18) right side, and safety protection device is limited the quantity of to the gas through air flue.Reduce when current limliting adjusting screw mandrel (16) revolves then specified current limliting amount inwards, otherwise increase.It is according to the fluid mechanics principle design, and when gas velocity surpassed certain value, ball cambered surface top relative pressure reduced, the ball come-up, because the effect of air-flow, the ball strain cooperates with ball sealing is airtight, cuts off gas circuit, thereby reaches the generation of the accident of preventing and the expansion of disaster.
The timing closing mechanism device, be installed on the air flue of air outlet one side, the break-make of air flue, by valve combination (12) control, the action of valve combination (12) is subjected to the restriction of timer, the control of duration of ventilation, set by the knob (1) on the timer indicator panel (2), timer belongs to prior art for existing parts, during installation, isolation diaphragm (6) cooperates with timer (5) and is abutted against; Simultaneously, an end of valve combination (12) and isolation diaphragm (6) near, the other end puts tower spring (11) back and valve pressing plate (10) is abutted against; Isolation diaphragm (6) jack-up valve makes up (12) and compresses tower spring (11) and open air flue when knob (1) open mode; When knob (1) turn-offed, promptly when timer (5) arrived zero-bit, isolation diaphragm (6) was because under the effect of tower spring (11), source of the gas is turn-offed in valve combination (12), reaches the control of duration of ventilation.
