Abstract
An improved structure of differential pressure disc for water heater is in particular used for switch of water-igniting water heater. A chamber formed by an upper casing and a lower casing in tight connection comprises a differential pressure film, a pressure plate, and a spring. The upper casing is equipped with a connecting hole of the electronic inductance valve. The lower casing comprises a back pressure inlet, a master inlet, a gas flow guiding valve hole, and a front valve hole. The gas flow guiding valve hole is started and stopped by a flange block on the differential pressure film. The design enables integrality between the differential pressure device and the gas valve, thus the functions of both the differential pressure and the gas valve flow can be accomplished in the same structure, which reduces cost as well as lessens potential risks of leakage caused by extra connection and extra push rod.
Description
The utility model relates to the architecture advances of water lighting water heater pressure differential disc.
Water heater water lighting formula gas switch is mainly by water pond, pressure differential disc and cooperate various valve bodies to assemble.When its maximum characteristics are opened the water source exactly, directly by water flow pressure through water pond conducting valve body switch and by pressure differential disc conducting gas valve body, light burning things which may cause a fire disaster to reach the purpose of burning heat-obtaining water by ignition system again, and pressure differential disc is to be most important element in the said structure, and it has worked the unlatching shunting action of keeping gas.Yet present pressure differential disc structure is unsatisfactory, diaphragm valve and diaphragm are separate type, push rod is established in the centre, easy recurring structure problem, and volume is big, the one-tenth height, as shown in Figure 1 and Figure 2, this pressure differential disc (1 ') is exactly to install a valve body (2 ') in addition, utilize the unlatching closure of the push-rod piston (3 ') in the valve body, and cooperate water pond pull bar piston (5 ') can control the action of malleation valve opening, back pressure air inlet (6 ') and female fiery air inlet (4 '), reach the gas conducting and light, Fig. 1 is a closed condition, and Fig. 2 is an opening.But this complex structure, cost improves relatively, and the danger that exists leakage to be caused, and is real undesirable.
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of to society melts Differential Pressure Unit and the gas valve body is the water heater pressure differential disc of one, pressure reduction function and the effect of gas valve stream is finished, to reach the purpose that reduces cost by same structure.
Realize that design of the present utility model is to fix a pressure reduction diaphragm and a pressing plate in the chamber of the upper cover body that connects by combining closely and lower cover, this pressure reduction diaphragm is divided into plemum and back pressure chamber with chamber, the cone of the indent of upper cover body design that the electronic induction valve is installed will be provided with, spring is located at cone upper support pressure reduction diaphragm and pressing plate, lower cover design back pressure air admission hole, female fiery air admission hole, gas water conservancy diversion valve opening that communicates with gas catheter and the malleation valve opening that connects the gas main valve, on the pressure reduction diaphragm, design a flange piece greater than gas water conservancy diversion valve opening simultaneously, in order to open and close this valve opening.
The utility model is compared with known technology, and it combines Differential Pressure Unit and gas valve body structure together, and pressure reduction function and the effect of gas valve stream are finished by same structure, has reached to reduce cost, reduce dangerous purpose.

Be described in further detail by above-mentioned accompanying drawing embodiment below.
The improvement structure of water heater pressure differential disc (referring to Fig. 3-4) is by last, lower cover (1), (8) combine closely and be provided with the pressure reduction diaphragm (7) that is fastened in the lid faying face in the chamber that is formed by connecting, chamber is separated into plemum (15) and back pressure chamber (6), pressure reduction diaphragm (7) has the annular groove that clamps pressing plate (5) and locates over against a watt phase water conservancy diversion valve opening (13), flange piece (11) greater than the aperture, the spring (4) that is contained on the interior concave cone of upper cover body (1) (3) is supporting pressing plate (5) and pressure reduction diaphragm (7), upper cover body (1) also is provided with the valve that the electronic induction valve is installed and connects hole (2), lower cover (8) also has back pressure air admission hole (9) and female fiery air admission hole (10) of control pressure reduction diaphragm (7) action, and be communicated with to flow into main burner gas tube (12) gas water conservancy diversion valve opening (13) and connect the malleation valve opening (14) of gas main valve, the flange piece (11) of the pressure reduction diaphragm (7) of rubber system is a keying gas water conservancy diversion valve opening (13).
As can be seen from Figure 4, the utility model utilization is fallen pull-type water pond interlock valve (A) control and is flowed to by the gas that gas channel (B) enters, when interlock valve (A) is opened, gas just enters, back pressure chamber (15), (6), and light female fiery through the igniting action through the ventilation primary fire pipe (not shown) of back pressure chamber (6), burning inductive needle simultaneously and turning circuit and shut off differential pressure magnetic valve (C), make gas no longer enter back pressure chamber (6), the pressure of plemum this moment (15) and diaphragm (7) the area power that is produced that multiplies each other are drawn back main valve flange piece (11) greater than spring (4) elastic force, and this water conservancy diversion valve opening (13) of then main tile promptly enters gas and by female fiery ignition combustion (blacking solid line position among the figure).
Below by Fig. 5, the switch motion process that Fig. 6 installs one group of indirect type magnetic valve for example makes a presentation, wherein magnetic valve and water pan structure are not this case theme so be not described further, only the action that just is used with pressure differential disc describes in detail: the pressure differential that water pond A mat flow produces promotes push rod (A1), promote the startups pole socket (B1) in the valve mechanism (B4) again and drive starting bar (B2) displacement promotion microswitch (B3) and switch on, make the long-pending magnetic of E type electromagnet (B) and with I sections piece (B5) adhesive mutually, water pond push rod this moment (A1) action still continues passing and depresses lever (B8), drive and the affixed connecting rod (B7) of I sections piece (B5), draw back main gas valve (C1), then gas is thus in malleation valve opening (14) flows into the plemum (15) of pressure differential disc, again through back pressure air admission hole (9) by preceding primary fire pipe (C2) in the sensible heat valve flows into back pressure chamber (6), make pressure reduction diaphragm (7) in just, under the state that back pressure chamber pressure equates, pressed down by the interior spring (4) of upper cover body (1), make flange piece (11) the sealing gas water conservancy diversion valve opening (13) of diaphragm (7), this moment, gas was divided into twice, together flow into the igniting jet pipe and by the nipple ejection of end through back pressure chamber (6) by the back pressure pore (9) of lower cover (8), and light lighter flame relatively and burn and touch the thermoinduction pin thermoinduction valve cuts out, this moment, gas no longer entered in the back pressure chamber (6), its pressure is disappeared, and push away diaphragm (7) on the pressure of plemum (15), opening gas water conservancy diversion valve opening (13) heats up water in gas catheter (12) flows into main burner, so far, finish whole breakdown action.
The utility model pressure differential disc also can use with the non-electronic valve switch combination of direct-type and reach identical purpose.
