Background technique
At present, gas water-heater and electrothermal heater have popularized numerous users, and the thermostat valve in the water heater is a critical component of regulating water temperature.Especially the thermostat valve of gas water-heater is subjected to pressure, the flow velocity of combustion gas, the influence of flow uncertain factor, is directly connected to the stability of its performance.Therefore, its structure is impelled the raising of stability in continuous optimization.Application number 02114998.4, " gas water-heater opens and closes trigger type aqueous vapor interstage valve with magnetic circuit " disclosed, this interstage valve be at present by the compressing of lever sheet with discharge sensitive switch by key pin, realize the break-make of contact, reach on the basis of pulse igniting controller opening and closing gas water heater working and improve.To lean on the water valve body end in the linkage valve of aqueous vapor interstage valve, fix a bowl-shape magnetic bowl of foraminate opening shape that make with permeability magnetic material, middle, and in the magnetic bowl, fix a foraminate permanent magnet in centre, the other end of little shaft retaining ring is equipped with a foraminate magnetic circuit close out sheet that make with permeability magnetic material, middle on little axle, and close magnetic bowl and permanent magnet place are fixed with the magnetic control induction switch element of a magnetic control dry reed-pipe or magnetic control Hall circuit outside linkage valve.This aqueous vapor interstage valve design proposal can realize that the switching with the water route reaches the automatic work and the purpose of closing of control gas water-heater, and outside linkage valve no any movable member.But this part patent is not introduced to the market as yet in application, exists design yet and owes reasonable part.
Summary of the invention
The utility model is that the like product that will be put to implement improves, and a kind of volumetric gas water heater thermostat valve that project organization is comparatively compact reduces required material, cost of production, simplifies assembly technology, shortens installation time.Now in conjunction with the accompanying drawings, its feature is described as follows:
A kind of volumetric gas water heater thermostat valve, this thermostat valve comprise temperature-sensitive pipe assembly 1, valve body 5, temperaturing control pressure seat 24, solenoid valve assembly 29, push rod assembly 33, it is characterized in that:
A), the axis on the plug 1-1 top in temperature-sensitive pipe assembly 1 and the recess axis of bar bar 2 are equal to;
B), an end and the temperaturing control pressure seat 24 of lever 2 connect, the other end of temperaturing control pressure seat and spring sheet 23, temperaturing control pressure seat sealing gasket 22, steel wire packing ring 21 connect, the other end of lever and push rod 3 connect;
C), push rod 3 is nested by guide sleeve 4, its afterbody is by inlay 8 phase embeddings, and links to each other with hex screw 11, another one of hex screw is connected with adjusting screw 12, and fixing by tightening nut 10;
D), adjusting screw 12 is connected with temperature adjustment knob 9;
On the coaxial line of temperaturing control pressure seat 24, be provided with aluminium lid 14, tower spring, be lined with aluminium lid seal ring 15 at the convex shoulder of aluminium lid.
Temperature-sensitive pipe assembly 1 is made up of expanded by heating amount big copper tube 1-2 and the small plug 1-1 of expanded by heating amount, two kinds of materials tighten together at temperature-sensitive pipe assembly 1 head, be heated the back because two kinds of material swell increment differences, contract thereby cause in the plug, lever 2 top 3 suffered power are changed, impel temperaturing control pressure seat 24 slowly to be returned to state when not heating.When the power that acts on spring sheet 23 less than certain value, spring sheet 23 is replied, and sounds, aluminium lid 14 is returned to reset condition under the effect of tower spring 13, close main air outlet passage.
During work, rotary temperature adjusting knob 9 is to temperature required, temperature adjustment knob 9 acts on push rod 3 by hex screw 11, the push rod 3 stressed levers 2 that act on, utilize lever 2 principles, keeping under the constant situation of plug 1-1 length, power transmission is in temperaturing control pressure seat 24, make temperaturing control pressure seat 24 suppressing action power in spring sheet 23, when power acquires a certain degree, spring sheet 23 work, sound, because spring sheet 23 acts on power that aluminium lid 14 produced and acts on the power of aluminium lid 14 greater than tower spring 13, make between aluminium lid 14 and the valve body 5 and produce the gap, thus conducting master gas port passage.

Embodiment
Mode of execution is an example with volume adjusted formula water heater thermostat valve.Earlier thermocouple is threaded to (see figure 3) on the solenoid valve assembly 29 before regulating, the Chang Minghuo mouth connects Chang Minghuo fire tube, suction port, air outlet and connects pipeline respectively; Thereafter, temperature adjustment knob 9 (Fig. 1) clockwise direction is threaded to the bottom, spool knob 18 is indicated the PILOT recess aim at the valve gap central position, combustion gas and Chang Minghuo road have promptly been connected.This moment, open the gas inlet pipe road, pressing push rod 3, burning torch button, the Chang Minghuo pipe mouth of pipe produce under the Mars effect at burning torch and light.Thermocouple is because the generation DC electrical source of being heated, thereby makes 29 adhesives of solenoid valve assembly.Decontrol pusher button 32 and burning torch button, gas guarantees that through solenoid valve assembly 29, spool 16, filter screen 31, ever-burning flame adjusting screw 30 holes, arrival Chang Minghuo air outlet hole ever-burning flame is flame-out in the operating time.
Heating schedule: rotary spool knob 18 is to main airway ON (Fig. 4), rotary temperature adjusting knob 9 is to required temperature, setting temperature scope: 30～73 ℃, produce spring under the plug of aluminium lid 14 in hex screw 11, push rod 3, lever 2, temperature-sensitive pipe assembly 1, temperaturing control pressure seat 24, spring sheet 23 actings in conjunction, gas arrives air outlet channel through spool 16, aluminium lid 14, arrives water heater ignition dish through main airway then, light the ignition dish, water heater is heated.
When water temperature reached setting temperature, the plug that the temperature-sensitive pipe assembly the is 1 li generation deformation of being heated acted on temperaturing control pressure seat 24, spring sheet 23, impels aluminium lid 14 to be returned to sealing state, the main airway stuffiness, and the ignition dish is flame-out, stops heating.
When water temperature drops to uniform temperature, temperature required low 14～18 ℃, thermostat valve then heats by above-described heating schedule again.
When closing, close gas source earlier, rotary spool 18 turns clockwise temperature adjustment knob 9 on earth to closing OFF (Fig. 4), thereby closes gas residual in the whole pipeline.
