Due to the design, the original design product can be completely replaced, the cost of a manufacturing process and materials can be further reduced, resources are saved, and the proportional valve with the improved structure is convenient to install.
Description
Technical field
The utility model relates to a kind of gas valve, relates in particular to a kind of architecture advances type Proportional valve.
Background technique
The fuel gas inlet pressure of combustion gas tool is not constant in practice, and the inlet pressure of fluctuation causes gas outlet pressure also along with variation, causes situation instability in the burning, for gas water-heater, will cause the situation that water temperature is sometimes hot and sometimes cold.Therefore need a kind of pressure regulator to come pressure is regulated, what keep-up pressure is stable.The proportional control technology is to realize the technological means of linear relationship between the controlled variable of element or system and the controlled quentity controlled variable, relies on these means to guarantee that output quantity size must change with input quantity in the ratio of determining and changes.So the combustion gas proportional control valve on the market has just produced, it is exactly the device of the traffic engineering capability of control combustion gas, generally be divided into moving-magnetic type Proportional valve and moving-iron type Proportional valve according to the Proportional valve principle, moving-iron type Proportional valve preparation process height, cost is just high naturally, and but performance is general, so moving magnetic structure Proportional valve is adopted in design mostly, in addition, combustion gas moving-magnetic type Proportional valve substantially all is the combined type Proportional valve in order to save on the cost structure on the open market.There is dual functions in Proportional valve portion wherein, be Proportional valve be again stop valve.Can save a stop valve like this, but also sacrifice its performance, as little fire can not transfer very little, and stable inadequately, flame-out easily, so the function of stop valve is also not ideal enough.
The general Proportional valves that have two by function on the market, all be to be used for the bigger water heater that rises number, stable performance, this Proportional valve on the market is to be assembled into than valve body from valve body and one by one in shape, two self-priming valves (being stop valve) are installed on valve body, than adorning a Proportional valve on the valve body, because volume is big, the characteristics that have inconvenience to install, add product complexity, manufacture cost height, so the market price is also than higher.
Summary of the invention
The utility model at the medium and small fire of prior art can not transfer very little, and stable inadequately, flame-out easily deficiency provides a kind of architecture advances type Proportional valve.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of architecture advances type Proportional valve, comprise from valve body with than valve body, be provided with suction port, on valve body, also comprise first stop valve and second stop valve from an end of valve body, a described end than valve body is provided with the air outlet, from valve body with connect as one by being connected air cavity than valve body.The gas ratio valve of this architecture advances type, be fully independently a combined type Proportional valve of routine valve function too, the characteristics of the Proportional valve maximum after the improvement are exactly under the prerequisite that guarantees installation dimension invariant position, retentivity stabilizability, are that disjunctor design, volume are little from valve body and Proportional valve.This design fully can substitute original deisgn product, and more can reduce manufacturing process and cost of material, has saved resource and has been convenient to and installed.
As preferably, communicate from the suction port and first air cavity of valve body, first air cavity be connected air cavity and communicate.The suction port and first air cavity are controlled by first stop valve, first air cavity be connected air cavity and control by second stop valve.
As preferably, connect air cavity and communicate with second air cavity than valve body, second air cavity and air outlet communicate.Intake process is to be ventilated by suction port earlier, is successively to pass through first air cavity earlier, connects air cavity then, by second air cavity, comes out the completed percentage adjustment process at last from the air outlet than valve body again.
As preferably, the side of air outlet has air outlet hole.Make things convenient for external equipment to test chamber pressure.
As preferably, than the spool lower end of valve body magnet steel is housed, the top of magnet steel is epithelium and compression plate, by elastic card magnet steel, epithelium and compression plate and spool is fixed.
As preferably, than the below of valve body the ratio coil is installed, the ratio coil inside has screw press.Secured core with the coil centre after the ratio coil electricity produces the power in a magnetic field, the magnetic force just in time magnet steel magnetic with the spool upper end is identical, whole mobile according to the principle that the same sex is repelled each other spool, by changing the coil current size, increase or reduce the magnetic force of coil, with the repulsion of magnet steel, reach change spool and sealing valve port gap, promptly finish the purpose of adjustments of gas flow size.
According to the technical solution of the utility model, under the prerequisite that guarantees installation dimension invariant position, retentivity stabilizability, be that disjunctor design, volume are little from valve body and Proportional valve.This design fully can substitute original deisgn product, and more can reduce manufacturing process and cost of material, has saved resource and has been convenient to and installed.
