Description

Timing valve

The utility model relates to a kind of valve of the cut-out air-flow that activates with mechanical timer, is the timing valve that a kind of novel gas kitchen range is used.

The gas cooker of Chu Shouing generally is unworthy of timing control apparatus in the market.Because the fire of gas cooker is stronger, is unworthy of timing valve and just can not cuts off combustion gas automatically on time.So when cooking, often need the people and keep an eye on, in case burn or catch fire.Especially when some food need boil the long period, the people can not leave and do other affairs, loses time, and uses little ideal.

The purpose of this utility model is: provide the energy timing turning off that uses on a kind of gas cooker combustion gas, timing valve easy to use.

The technical solution of the utility model is: timing valve comprises a common timer, its characteristics are: the valve casing of fixedlying connected with the timer housing has two chambeies of A, B, A, B chamber each have the interface of a logical fuel tube, A, B have vent between the chamber, utilizing spring to be fixed on plug on the valve casing just in time drops in the vent between A, the B chamber, the center fixation of round rail head jaggy is on the clockwork spring running shaft of timer, the tail end that is enclosed within the push rod in the retainer ring is aimed at plug, and the head end of push rod is to the track of director circle rail head.Be the sealing plate in B chamber between plug and the push rod afterbody, sealing plate is formed by the elastomeric layer of hard plate with holes and sealing, and the afterbody of push rod is aimed at the hole of this hard plate.Fix a lump on the sealing plate of aligning plug.The head of push rod has wheel.There is boss at the center of circle rail head, and the hole that matches with the clockwork spring running shaft is arranged in the boss, on the track of circle rail head concave indentation is arranged.Valve casing can be circular, square or other shapes.

The utility model has the advantages that: simple in structure, this timing valve is contained on the gas cooker, can be according to the length of period of combustion, adjust timer, because the clockwork spring running shaft of timer is fixedlyed connected with round rail head jaggy, directly drive the rotation of circle rail head valve body, can accurately cut off combustion gas according to the time, easy to use, save time.

Embodiment 1:

With reference to accompanying drawing 1-20, the enforcement of timing valve is as follows, make base plate cover 1 (seeing Fig. 2-4), plug 3 (seeing Fig. 8-10), push rod 6 (seeing Figure 15-17), retainer ring 18 (seeing Figure 14), seal diaphragm 16 (seeing Figure 11-13), the breach of valve chest 5 (seeing Fig. 5-7) valve casing with mould and justify rail head 7 (seeing Figure 18-20), material can be aluminum alloy or other metal.The fixing welding intake interface 4 and the interface 13 of giving vent to anger on the wall of valve chest 5, so that be connected with steam outlet pipe with the suction tude of gas cooker, intake interface 4 communicates with the A chamber of valve casing, the interface 13 of giving vent to anger communicates with the B chamber of valve casing.The base plate cover 1 of valve casing is screwed on the earhole 14 of valve chest 5 bottoms, adds one deck rubber in order to be sealed in the inside.One end of spring 2 is fixed on the inner face of base plate 1, and the other end of spring 2 is fixedlyed connected with plug 3, and the head of plug 3 just in time drops in the vent 19.Utilize the earhole of valve casing inwall the periphery of seal diaphragm 16 to be fixed on the inwall of valve chest 5, on seal diaphragm 16, add one deck rubber layer 20, aim on the rubber layer 20 of plug 3 head place sealing plates 16 and fix a Hard Roll piece 21, porose on the sealing plate 16 below the Hard Roll piece 21.Retainer ring 18 usefulness screws or rivet are fixed on the earhole of valve casing 5 inwalls.The shaft of push rod 6 is enclosed within the retainer ring 18.With screw 17 and fastening screw 8 breach circle rail head 7 is fixed on the clockwork spring running shaft 11 of timer 9.The mechanical timer that timer 9 adopts watch factory, granary, Jiangsu to produce, just the clockwork spring running shaft stretches out housing.The concave indentation of circle on the rail head 7 in orbit, the wheel of the head of push rod 6 is to the track of director circle rail head 7.Timer 9 is fixed on the earhole in the valve casing 5 by hole 12 with screw.Rotatable handle 15 matches with running shaft 11, is used for the control time.Screw hole 10 on timer 9 housings is used for timer is fixed on the panel of gas cooker.So far, timing valve is implemented to finish.

During use, intake interface 4 is connected on the suction tude of gas cooker, interface 13 is connected on the pipeline of igniter one end with giving vent to anger.When time switch was put O, the head end of push rod 6 placed the breach of round rail head, and plug 3 falls the hole 19 between A chamber and the B chamber is blocked, and air-flow is obstructed.Rotatable handle 15 is rotated, after also promptly opening switch, push rod 6 moves on the circular orbit of non-breach, the tail end of push rod 6 pushes plug 3 and rises, the A chamber is communicated with B chamber air-flow, also is that the air-flow of gas cooker communicates, when push rod 6 moves to breach, plug 3 falls to blocking hole 19, when just cutting off air-flow.Use easily.

Another makes usage be, on the suction port of gas cooker and the pipeline between the igniter, tap into bronchus and go out bronchus, advance the suction port of bronchus near gas cooker, go out bronchus near igniter, the intake interface of timing valve is connected on on the bronchus, the interface of giving vent to anger is connected on out on the bronchus, is advancing bronchus and is going out the ball-type selector switch of adorning a common usefulness on the pipeline between the bronchus in addition.During without timing valve, selector switch is opened, and air-flow is from original pipeline circulation.When needing to use timing valve, selector switch cuts out.Combustion gas flows to a steam outlet pipe from suction tude through a timing valve, and inlet point firearm then reaches the purpose of timing turning off air-flow.
