Abstract
The utility model relates to an electromagnetic gas valve, comprising a valve body, valve plug rods, a push rod and an electromagnetic coil. The sealing film which is fixed on the valve body and is used for sealing off the communication between the valve body and outside world is a bowl-shaped film. The push rod which is driven by the electromagnetic coil and the valve plug rods of two venting chambers inside the sealed valve body are respectively positioned above and below the bowl bottom of the bowl-shaped film. Meanwhile, sealing gaskets which are arranged on the valve plug rods are annular sealing gaskets.
Description
The utility model relates to valve, is a kind of electromagnetic gas valve.
All dispose burnt gas valve on the gas kitchen ranges, particularly on the automatic control gas-cooker that can light a fire, cut off automatically source of the gas automatically, generally all dispose the electromagnetic gas valve, control the closure of gas valve with the control circuit of the protective device of gas-cooker.Existing be used for that electromagnetic gas valve on the gas kitchen ranges is general main to be made of valve body, valve cock stem, solenoid, push rod, sealing film etc., sealing film is fixed on valve body and the extraneous valve port that communicates, also be screwed simultaneously to be connected and be positioned on the push rod that valve body is subjected to the solenoid restriction outward, and push rod and valve cock stem also directly fuse.Electromagnetic gas valve so, when electronic control circuit drives the solenoid action and when driving the push rod displacement, push rod drives the valve cock stem motion that is attached thereto and valve closing.Existing this electromagnetic gas valve seal is bad, sealing film particularly, because this planar shaped sealing film is connected with push rod, the deformation range of planar shaped film itself is very little on the one hand, and it does not allow push rod that any rotation is arranged yet, otherwise film is damaged easily, causes gas leakage.Be arranged in addition that the sealing gasket in order to seal valve seat is a kind of O-ring seals on the valve cock stem, it is line with valve seat and contacts, and gas leakage also easily takes place.Valve leak is very dangerous, because people are difficult for discovering, and maintenance is also difficult, and a large amount of leakage causes personal injury easily.
The purpose of this utility model is for a kind of gas kitchen ranges electromagnetic gas valve with excellent sealing and reliable operation is provided, to improve the use security personnel performance of gas kitchen ranges.
Realize the utility model of above-mentioned purpose, the same with existing solenoid gas valve, mainly include valve body, have valve cock stem, solenoid, the push rod of sealing gasket and be fixed on the sealing film that communicates with the closed valve and the external world on the valve body.Have two in its valve body and be communicated with but spaced-apart venting cavity and connected chamber, one of them venting cavity is connected with admission line, and another venting cavity is connected with outlet pipe; Valve cock stem is set in the connected chamber of valve body, and corresponding with push rod, and push rod is with the action campaign of solenoid.The design's characteristics are that sealing film is designed to bowl shaped structure, push rod and valve cock stem lay respectively at the upper and lower at the bottom of the bowl of this bowl-type film, and the sealing gasket in order to seal valve seat is designed to loop configuration on the valve cock stem being arranged in the design, this Gask-O-Seal compresses with the spring roof pressure, face contacts to make it to have closely with valve base chamber, to guarantee in the valve body sealing between two venting cavities.So the working method of the electromagnetic gas valve of structure is, when operating push rod to bottom offset, push rod promptly promotes bowl-type film and related promotion valve cock stem to bottom offset, at this moment, Gask-O-Seal is lifted off a seat, and interior two venting cavities of valve body is communicated, to the burner air feed of gas-cooker, simultaneously, sealing gasket makes the spring compression.Lived by holding when being displaced to certain distance downwards, so the valve seat place is opened always because of push rod; When removing the constraint to push rod when action under the driving of solenoid at control circuit, push rod is to top offset, and the bowl-type film resiles, and the Gask-O-Seal on the valve cock stem is pressed on the valve seat at the effect lower cover of top pressure spring, reaches the purpose of closing valve.
Therefore, the utility model has the advantages that, the inside and outside bowl-type sealing film of closed valve all breaks away from push rod and valve cock stem, even therefore push rod rotates also can not draw and decreases the bowl-type film, solved valve body and extraneous sealing problem effectively, and, the good springiness of bowl-type film, deformation range is big, can guarantee the ventilation of two venting cavities in the valve body.Secondly, the seal of two venting cavities is Gask-O-Seals in the closed valve, is face with valve seat and contacts, and has improved the sealing of air valve closed condition effectively.Therefore, have more higher fail-safe behind use the utility model on the gas kitchen ranges.
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described specifically.
Description of drawings:
Accompanying drawing is a structure cutaway view of the present utility model.
See that by figure 12,13 and connected chambers 7 that are communicated with this two venting cavity and communicate with the external world of two venting cavities are arranged in the valve body 1. Venting cavity 12,13 is connected with gas pipeline, valve cock stem 2 in the connected chamber 7 is set in the pole socket 11 that is fixed on the valve body 1, then valve cock stem 2 can be done upper and lower displacement in this pole socket 11, and this valve cock stem 2 is provided with Gask-O-Seal 9, holds out against on the valve seat 8 of valve body 1 with spring 10.See by figure, the exit, upper end of connected chamber 7 is fixed with bowl-type film 3, the top of this bowl-type film 3 is a push rod 4, push rod 4 and valve cock stem 2 coaxial settings, push rod 4 devices are in ram seat, ram seat one side is being fixed solenoid 6, and the backstay 5 that is positioned at solenoid 6 centers can head into the lock slots of push rod 4.
