Abstract
A water-gas linkage valve includes a water valve body assembly (1) with a high pressure water chamber (121), a gas valve body assembly (2), a linkage assembly (3) for connecting the gas valve assembly (2) with the water valve body assembly (1), and a low pressure water chamber (122). A gas outlet (32) is provided in the linkage assembly (3). The low pressure water chamber (122) is connected with the high pressure water chamber (121) by a venturitube (13). The low pressure water chamber (122) is provided in the water valve body assembly (1). A pressure transmission unit is formed when the water valve body assembly (1) is connected with the linkage assembly (3). The pressure transmission unit is isolated from the high pressure water chamber (121) and the low pressure water chamber (122) by a diaphragm (131,132). The linkage assembly (3) is controlled by the water valve body assembly (1) based on the change of the pressure difference between the high pressure water chamber (121) and the low pressure water chamber (122), and then the linkage assembly (3) controls the open and close of the gas in the gas valve body assembly (2). Since the high and low pressure water chambers (121,122) are isolated from the linkage assembly (3) by the diaphragm (131,132), it avoids the water directly touching with the metal parts of the linkage assembly and effectively prevents sediment incrustation and corrosion.
Description
Technical field
The present invention relates to water vapor linked valve, there is the water vapor linked valve of incrustation and corrosion phenomena in especially a kind of valve inner that prevents for gas heater.
Background technology
In gas heater use procedure, control air valve by water valve, in the time that water valve is opened, control air valve and open, when water valve cuts out, control air valve closure, thereby realize the synchro switch of bath water and combustion gas, i.e. Water-gas linkage.
Referring to Fig. 1, it is the cutaway view of water vapor linked valve in existing gas heater.The water valve body assembly 1 ' of water vapor linked valve comprises high-pressure water chamber 12 ', after being connected with linkage unit 3 ', water valve body assembly 1 ' forms low pressure water cavity 14 ', between high-pressure water chamber 12 ' and low pressure water cavity 14 ', utilize the 13 ' isolation of pressure differential disc barrier film, run through the little axle 31 ' of interlock of linkage unit 3 ' on low pressure water cavity 14 ' side center line, barrier film cushion rubber seat 15 ' is withstood in link one end of little axle 31 ', barrier film cushion rubber seat 15 ' holds out against pressure differential disc barrier film 13 ', and the other end of the little axle 31 ' that links withstands the packing holder 22 ' of gas valve body assembly 2 '.
When current flow into the pipeline of water valve body assembly 1 ' from flow inlet 11 ', first enter in high-pressure water chamber 12 ', after high-pressure water chamber 12 ' flows out, then flow into Venturi tube 16 ', finally enter in heat exchanger.In the time that current are flowed through Venturi tube 16 ', the pressure decreased of locating current in the throat 161 ' (being minor diameter part) of Venturi tube 16 ' is (in Fig. 1, filled arrows represents the flow direction of current), water in low pressure water cavity 14 ', in throat's 161 ' pressure of Venturi tube 16 ', is delivered to the low pressure of throat 161 ' in low pressure water cavity 14 ' through pressure tube 17 '.Now, the pressure of high-pressure water chamber 12 ' is greater than low pressure water cavity 14 ', water under high pressure promotes pressure differential disc barrier film 13 ' and moves to the direction of low pressure water cavity 14 ', promoting the little axle 31 ' of interlock moves to the direction of packing holder 22 ' again, thereby back down packing holder 22 ', make the combustion gas of fuel gas inlet 21 ' enter into burner apparatus, realize heating.
In the time that water valve cuts out, current no longer enter into high-pressure water chamber 12 ', in high-pressure water chamber 12 ', pressure is reduced to gradually with the pressure of low pressure water cavity 14 ' and equates, pressure differential disc barrier film 13 ' falls after rise, in valve, outer spring 23 ' resets, and top tight sealing seat 22 ', thereby reach the object that blocking-up combustion gas enters into burner apparatus, prevents dry combustion method.
Due to water vapor linked valve in use, in high-pressure water chamber 12 ' and low pressure water cavity 14 ', be all full of water, the one end and the sealing nut 32 ' that are arranged in the little axle 31 ' of interlock of low pressure water cavity 14 ' are immersed in water.Therefore, the water vapor linked valve long period works and easily produces fault in the poor environment of condition of water quality, in the time that bath water water quality contains more suspended material or colloid more firmly and wherein, in low pressure water cavity 14 ', easily form incrustation, especially link and easily stopped up by incrustation between little axle 31 ' and sealing nut 32 '; When being dissolved with higher concentration inorganic salts electrolyte (Na in bath water
+, Cl
-, sulfate radical etc.) and when oxygen, link between little axle 31 ' and sealing nut 32 ' easily by corrosion.Under the effect of incrustation scale and corrosion, water vapor linked valve easily occurs to be used after a period of time, the little axle 31 ' action that links in water vapor linked valve has some setbacks and even can not reset completely, thereby water vapor linked valve can not be closed completely, combustion gas still can enter into burner apparatus, burns away, thereby makes burner apparatus generation dry combustion method, damage gas heater, cause danger.
Summary of the invention
In order to overcome the problem that in the water vapor linked valve causing due to incrustation and corrosion, air valve can not normally be closed, technical scheme of the present invention is to provide a kind of water vapor linked valve, effectively solve the problem that the water vapor linked valve that causes due to incrustation and corrosion can not normally be closed, prevent dry combustion method and damage gas heater, increased the security performance of gas heater.
For solving the problems of the technologies described above, a kind of water vapor linked valve provided by the invention, comprising:
