Abstract
The utility model discloses a water-gas linkage valve of low staring pressure for a rapid gas water heater. The water-gas linkage valve comprises a linkage valve, and a water valve and a gas valve which are respectively arranged at the two ends of the linkage valve. A water pressure starting cavity is formed by combining the water valve and the linkage valve. A partition structure consisting of a rubber diaphragm and a diaphragm plate is arranged in the water pressure starting cavity, the water pressure starting cavity is divided into a balance water pressure cavity and a water pressure making cavity by the partition structure, and the water valve is communicated with the water pressure making cavity by a fluid channel. The utility model is characterized in that the capacity of the water pressure making cavity is smaller than or equal to the capacity of the balance water pressure cavity. The starting pressure of a water heater is improved by arranging bosses moving with the rubber diaphragm and the diaphragm plate on the rubber diaphragm and the diaphragm plate, so the water heater can even be normally started in low water pressure states. The normal life of users is ensured.
Description
Technical field
The utility model relates to the gas heater technical field, relates to a kind of being applicable to more specifically and makes the normal aqueous vapor interstage valve that starts of gas heater under normal hydraulic pressure and the low hydraulic pressure situation.
Background technology
Gas heater need could normally start under normal hydraulic pressure, yet resource scarcity now is to produce or the situation of hydraulic pressure deficiency all can appear in domestic water, particularly at floor than higher dwelling house, common gas heater can be because of the hydraulic pressure deficiency, and can't normally start.For this reason, people develop various aqueous vapor interstage valves to improve the starting pressure of water heater.At present, aqueous vapor interstage valve on the market mainly is made up of water valve 1, air valve 2 and interstage valve 3, as shown in Figure 1, water valve 1 and air valve 2 place interstage valve 3 two ends, and by the separation structure that diaphragm of rubber 4 and diaphragm plate 5 are formed the interstage valve inner chamber is divided into two cavitys and is communicated with air valve with water valve respectively, thereby increase the starting pressure of water heater, water heater is normally started.The shortcoming of this structure is that the contact-making surface of the diaphragm of rubber and the water conservancy diversion mouth of pipe is an arc, is easy to cause the insufficient pressure in the mozzle, can't start water heater fast.
Summary of the invention
The purpose of this utility model is exactly a kind of not only simple in structure, the environmental protection and energy saving that provide for the deficiency that solves prior art, and can shorten start-up time, ensures the gas instantaneous water heater low voltage starting aqueous vapor interstage valve of user security.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of gas instantaneous water heater low voltage starting aqueous vapor interstage valve, the water valve that comprises interstage valve and be divided into the interstage valve two ends, air valve, water valve combines with interstage valve and forms hydraulic pressure startup chamber, the hydraulic pressure startup is provided with the separation structure of being made up of diaphragm of rubber and diaphragm plate in the chamber, this separation structure will be divided into balance hydraulic pressure chamber and system hydraulic pressure chamber for hydraulic pressure starts the chamber, be communicated with by the fluid passage between water valve and the system hydraulic pressure chamber, it is characterized in that: the volume in described system hydraulic pressure chamber is less than or equal to the volume in balance hydraulic pressure chamber.
As further specifying of such scheme, described diaphragm of rubber is provided with the boss corresponding with the fluid passage, the surface of diaphragm plate is outwards protruded and is cooperated with the bottom of this boss is concavo-convex, and when water heater was in closed condition, the boss of described diaphragm of rubber can extend in the water valve fluid passage.
Be provided with gas passage between described interstage valve and the air valve, be provided with interlock valve, spring and air valve rubber in this passage, the middle part of interlock valve is provided with universal driving shaft, the junction that gas passage and hydraulic pressure start the chamber is provided with the interstage valve pressing plate, and universal driving shaft passes this interstage valve pressing plate and is connected with diaphragm plate.
The spool of described water valve is connected with mozzle, and the other end of this mozzle is communicated with system hydraulic pressure chamber.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts diaphragm of rubber and diaphragm plate to be provided with a boss that together moves with diaphragm of rubber and diaphragm plate, this boss can stretch in the fluid passage of water valve, and the volume in system hydraulic pressure chamber is less than or equal to the volume in balance hydraulic pressure chamber, help increasing the water heater starting pressure that hydraulic pressure starts the chamber, the dwelling house that solves story height is because of the not enough problem that can't start water heater of hydraulic pressure, to improving the toggle speed of gas heater, shorten its start-up time and have positive meaning.
