Description of drawings
Fig. 1 is the structural representation of a kind of slim gas ratio valve of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of slim gas ratio valve as shown in Figure 1, comprise valve body 1, first order solenoid valve 2, second level solenoid valve 3 and Proportional valve 4, first order solenoid valve 2, second level solenoid valve 3 and Proportional valve 4 are fixedly installed on the valve body 1, first order solenoid valve 2 is in the left bottom of valve body 1, second level solenoid valve 3 is in the upper right of valve body 1, second level solenoid valve 2 and first order solenoid valve 1 are placed in opposite directions, and Proportional valve 4 is directly over first order solenoid valve 2.First order solenoid valve 2 and second level solenoid valve 3 comprise black box, the black box of first order solenoid valve 2 cooperates with a valve port 101 of valve body 1, the black box of second level solenoid valve 3 cooperates with another valve port 102 of valve body 1, and first order solenoid valve 2 and second level solenoid valve 3 open or close valve port 101 and valve port 102 according to the electrical signal of controller.
A valve port 101 is the valve port of loosing core, and another valve port 102 also is the valve port of loosing core, and the passage 5 that valve port 101 is connected with another valve port 102 is the technology passage of loosing core, and passage 5 is provided with stainless steel plug 6 sealings.
First order solenoid valve 2 is provided with sealing gasket 9 with valve body 1 joint, and second level solenoid valve 3 is provided with sealing gasket 9 with valve body 1 joint.Proportional valve 4 connects patch cord 10.Valve body 1 is connected with air input joint 11, and Proportional valve 4 is connected with air outlet adapter.Valve body 1 is provided with O-ring seals 12 and filter screen 13 with air input joint 11 joints.
The air flow direction of this slim gas ratio valve: as shown in Figure 2, first order solenoid valve 2 and second level solenoid valve 3 are closed conditions among the figure, first order solenoid valve 2 and second level solenoid valve 3 are opened in the electrical signal control of controller, and ratio coil 402 control ball valves 407 are opened.Combustion gas enters by 1. locating, enter again 2. to reach 3. and locate, again from valve port 102 enter Proportional valve 4 4. again to 5., last gas flow turnover gas joint.
The adjustment process of Proportional valve 4: when ratio coil 402 controlled electric currents, lower end surface at magnetic core 401 produces and the identical electromagnetic field of permanent magnet 403 upper-end surface polarity, the principle of repelling each other by the same sex, the two produces repulsive force, promote permanent magnet 403 and ball valve 407 and move down, and form corresponding aperture between the ball valve mouth.Electric current increases, the corresponding increase in magnetic core 401 magnetic fields, and the power of pushing permanent magnet 403 open increases, and ball valve mouth aperture increases; Electric current reduces, corresponding the reducing in magnetic core 401 magnetic fields, and the power of pushing permanent magnet 403 open reduces, and ball valve mouth aperture reduces.Controller can be regulated electric current automatically by the water temperature feedback signal and realize controlling automatically gas flow like this, carry accurate ratio adjust system, really reach step-less adjustment, can adjust the flow of required combustion gas immediately, thereby reach the regulation and control water temperature, stablize the purpose of water temperature.
Electromagnetic force disappears when 402 outages of ratio coil, and permanent magnetism power is inhaled to magnetic core 401 permanent magnet 403, moves on the ball valve 407 and closes the ball valve mouth; Permanent magnet 403 is inhaled all the time to magnetic core 401 under off-position, and ball valve 407 is produced constant pulling force, makes ball valve 407 have sealing effect.
The voltage stabilizing process of Proportional valve 4: after electric current was determined by set temperature value, magnetic force can be considered a constant force.When the rising of combustion gas incoming pressure, diaphragm 406 stressed increases reduce ball valve mouth aperture to top offset, and the combustion gas delivery pressure is diminished; When the decline of combustion gas incoming pressure, diaphragm 406 stressed reducing to bottom offset increase ball valve mouth aperture, make the combustion gas delivery pressure become big.So guaranteed the stable of combustion gas delivery pressure, made combustion condition remain required state.
Above-mentioned embodiment is a preferred embodiment of the present utility model; can not limit claim of the present utility model; other any change that does not deviate from the technical solution of the utility model and made or other equivalent substitute mode are included within the protection domain of the present utility model.
