Description

A kind of aqueous vapor interstage valve with the combustion gas pressure maintaining valve
Technical field
The utility model relates to a kind of aqueous vapor interstage valve, specifically is a kind of novel aqueous vapor interstage valve of the band combustion gas pressure maintaining valve of using for gas water-heater.
Background technique
The used aqueous vapor interstage valve of existing gas water-heater does not all have the metastable gas pressure device, makes water heater in use like this, owing to each gas supply conduit pressure transient, and causes the water-exit temperature instability, the combustion condition state that waits not up to standard.In order to overcome this problem, a lot of manufacturers dispose a combustion gas pressure maintaining valve outside water heater, so not only influence the overall appearance of water heater, and inconvenience is installed, and voltage regulation result is undesirable.
The model utility content
At said circumstances, the purpose of a kind of aqueous vapor interstage valve with the combustion gas pressure maintaining valve of the utility model is to overcome the defective of existing product technology, provide a kind of and existing aqueous vapor interstage valve to have identical volume, installation dimension, versatility, voltage regulation result is good, the novel aqueous vapor interstage valve that has the metastable gas pressure device of compact structure.
For achieving the above object, a kind of technical characteristics that is adopted with the aqueous vapor interstage valve of combustion gas pressure maintaining valve of the utility model is: it comprises suction tude, contains the electromagnetism valve pocket of air outlet, sensitive switch, water valve device, interstage valve device, intake pipe, regulating the qi flowing in the channels spool, water transfer spool, this suction tude is connected with the electromagnetism valve pocket, it focuses on, this electromagnetism valve pocket air outlet is connected with the pressure maintaining valve air-inlet cavity, under the cold state of solenoid valve, this seal spool head gets lodged on the air outlet, the air outlet is closed, played the fuel gas path that sealing cuts off electromagnetism valve pocket and pressure stabilizing cavity; The pressure maintaining valve air-inlet cavity is communicated with pressure stabilizing cavity, and pressure stabilizing cavity connects an end of voltage stabilizing epithelium, and the other end of this voltage stabilizing epithelium connects stable-pressure device; This voltage stabilizing epithelium connects an end of voltage stabilizing spool, and the other end of this voltage stabilizing spool is established con cap body and placed throughput to regulate in the suction port in chamber the aperture of regulating suction port automatically.
In addition, this pressure maintaining valve is provided with controlling device, is provided with stable-pressure device between this controlling device and voltage stabilizing epithelium.
This controlling device is an adjusting nut, and this stable-pressure device is a pressure-stabilizing spring.
The utility model adopts said structure, its compact structure, and easy for installation, versatility is stronger, and voltage regulation result is better.It can solve the gas supply conduit pressure transient and the water temperature instability that causes effectively, defective such as combustion condition is not up to standard.
Description of drawings
Fig. 1 is the schematic perspective view of a kind of aqueous vapor interstage valve with the combustion gas pressure maintaining valve of the utility model;
Fig. 2 is the internal structure schematic representation of a kind of aqueous vapor interstage valve with the combustion gas pressure maintaining valve of the utility model.
Embodiment
As Fig. 1, shown in Figure 2, a kind of technical characteristics that is adopted with the aqueous vapor interstage valve of combustion gas pressure maintaining valve of the utility model is: it comprises suction tude 9, electromagnetism valve pocket 10, sensitive switch 12, water valve device 13, interstage valve device 14, intake pipe 15, regulating the qi flowing in the channels spool 4, water transfer spool 16, this suction tude 9 is connected with electromagnetism valve pocket 10, it focuses on, these electromagnetism valve pocket 10 air outlets are connected with pressure maintaining valve air-inlet cavity 1, under the cold state of solenoid valve, this seal spool head gets lodged on the air outlet, the air outlet is closed, played the fuel gas path that sealing cuts off electromagnetism valve pocket 10 and pressure stabilizing cavity 2; Pressure maintaining valve 11 air-inlet cavitys 1 are communicated with pressure stabilizing cavity 2, and pressure stabilizing cavity 2 connects an end of voltage stabilizing epithelium 6, and the other end of this voltage stabilizing epithelium 6 connects pressure maintaining valve 11; This voltage stabilizing epithelium 6 connects an end of voltage stabilizing spool 5, and the other end of this voltage stabilizing spool 5 is established con cap body 51 and placed throughput to regulate in the suction port in chamber 3 aperture of regulating suction port automatically.In this specific embodiment, this controlling device 7 is an adjusting nut, and this stable-pressure device 8 is a pressure-stabilizing spring.
When work, at first open the cold valves that feeds water heater, tap water enters water valve device 13 from intake pipe 15, under the promotion of hydraulic pressure, open interstage valve device 14 and sensitive switch 12, signal of controller is given in sensitive switch 12 action backs, and controller is started working follow procedure.At this moment combustion gas enters pressure maintaining valve air-inlet cavity 1, pressure stabilizing cavity 2 after by suction tude 9 and opened solenoid valve 10, gas pressure promotes the aperture that voltage stabilizing epithelium 6 is regulated voltage stabilizing spool 5 automatically, make the gas flow that enters throughput adjusting chamber 3 obtain control effectively on request, thereby reach the stable of gaseous-pressure output.Enter interstage valve 14 after opening by regulating the qi flowing in the channels spool 4 again through the combustion gas after the voltage stabilizing, enter the burner ignition at last, make the water heater proper functioning.Adjusting nut in the pressure maintaining valve 11, it can regulate before dispatching from the factory according to the different gas kinds in various places, air pressure; It is the compression ratio by the adjusting pressure-stabilizing spring, thereby reaches the voltage regulation result of gas water-heater under the state of different gas kinds, air pressure, makes gas water-heater be in good working order all the time.
The utility model adopts said structure, its compact structure, and easy for installation, versatility is stronger, and voltage regulation result is better.It can solve the gas supply conduit pressure transient and the water temperature instability that causes effectively, defective such as combustion condition is not up to standard.It is a kind of desirable aqueous vapor linkage valve of gas water-heater with built-in pressure maintaining valve.
In sum, the utility model provides the aqueous vapor interstage valve of a preferable feasible band combustion gas pressure maintaining valve, so offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be the utility model preferred embodiment, be not to limit to the utility model with this, be with, approximate with structure of the present utility model, device, feature etc., identical such as, all should belong to of the present utility model founding within purpose and the claim.
