Abstract
A flue gas proportional control valve assembly consists of two electromagnetic switch valves, a gas outlet adapter, a ball valve, a proportional valve body, a film, a dynamic permanent-magnet, a static permanent-magnet, an excitation winding, a support and a gas inlet connecting pipe. A secondary spring is completely removed from the proportional control valve part, the electromagnetic switch valves can be disposed in three directions, the angle of a plug sheet is changeable, the gas inlet connecting pipe is a split-type and can be prepared flexibly as per the demand, the gas outlet has three optional directions for meeting multiple modes, so that the practicality, reliability and security of the product are promoted. The utility model has reasonable design, compact structure, evidently promoted proportional control valve characteristics and can be extensively applied for all flue gas devices. The utility model can be matched with the relevant electrical control system for reliable automatic control on flue gas pressure and flow and has excellent pressure stabilizing function. A two-stage switch valve on a fuel gas channel can control the on/off of the fuel gas channel safely and effectively.
Description
Technical field the utility model combustion gas control ratio valve assembly belongs to the valve class in the mechanical engineering, particularly the operation equipment of electric or magnetic actuating.
Background technique is present, the domestic moving magneto Proportional valve of producing, be that permanent magnetism and ball valve are packed in one, the magnetic induction intensity of magnetostatic core is controlled by the electric current of field winding, and moving permanent magnetism and magnetostatic core make between ball valve and the valve body opening degree with the proportional variation of size of current by magnetic interaction.Between moving permanent magnetic part and other related components secondary spring is housed all on the structure, the characteristic return difference is big, and volume is bigger, and the air outlet direction is single.For example structures such as patent 99225340.3 gas water-heater Proportional valves, patent 98232957.1 pipeline gas low pressure valves, patent 99228336.1 little power consumption direct action solenoid valves are complicated, and volume is bigger, are not easy to install.
The technology contents the purpose of this utility model provides a kind of combustion gas control ratio valve assembly, and Proportional valve partly fully phases out secondary spring, and the ratio characteristic of making significantly improves.The two-stage electromagnetic switch valve can selective installation on three directions, the inserted sheet variable-angle, and air inlet tube is split type, can prepare flexibly on demand; The air outlet can selective installation on three directions; Adapt to different types of machines, the practicability and reliability and the Security that have greatly improved this product.The utility model is made up of electromagnetic switch valve (1), electromagnetic switch valve (2), air outlet joint (3), ball valve (4), Proportional valve valve body (5), diaphragm (6), moving permanent magnetism (7), magnetostatic core (8), field winding (9), support (10), air inlet tube (11), the break-make of secondary switch valve series connection control blast tube, proportional control does not partly have secondary spring, and electromagnetic switch valve (1), electromagnetic switch valve (2) are installed in parallel on the direction A or direction B, C of Proportional valve valve body (5) side; Air outlet joint (3) can be installed in the direction A or the last selection of direction B, C of Proportional valve valve body (5).The utility model is reasonable in design, compact structure, and the proportional control characteristic significantly improves, and can be widely used in all kinds of gas combustion apparatus.Unite use with corresponding electric control system, can implement automatic control reliably, and have good voltage stabilizing function gaseous-pressure, flow.
Description of drawings Fig. 1 is the utility model structural drawing; Fig. 2 is the utility model electromagnetic switch valve (1) installation direction B, C schematic representation; Fig. 3 is the utility model electromagnetic switch valve (2) installation direction B, C schematic representation; Fig. 4 is the utility model air outlet joint (3) installation direction B, C schematic representation;
Embodiment is in the utility model, as shown in Figure 1: be on the basis of the secondary spring in the domestic existing proportional control valve of cancellation, two electromagnetic switch valves be installed in parallel in the side surface direction A of Proportional valve valve body (5).As shown in Figure 2, can electromagnetic switch valve (1) be installed on direction B or C according to user's needs.As shown in Figure 3, can electromagnetic switch valve (2) be installed on direction B or C according to user's needs.As shown in Figure 4, the air outlet is also taken over and can be installed on the side surface direction B of Proportional valve valve body (5) or C according to user's needs.Saved secondary spring, saved cost, the proportional control valve characteristic significantly improves.Two-stage electromagnetic switch valve (1), (2) parallel installation, height dimension is little, compact structure.The utility model can be widely used in all kinds of gas combustion apparatus, as gas water heater, heating, the dual-purpose water heater of bathing, baking oven etc., unite use with corresponding electric control system, can implement automatic control reliably combustion gas (natural gas, artificial coal gas, liquid gas) pressure, flow.During enforcement, main valve body, Proportional valve valve body, air inlet tube and air outlet joint are aluminium alloy compression casting after machining forms, bend formings such as solenoid valve support, magnetostatic core and moving magnetic core are heat-treated after adopting electromagnetic pure iron processing again, field winding is formed by the numerical control filament winder coiling, various working of plasticss, rubber parts, spring, standard piece cooperation processing, because the strict demand of products air tightness and ratio characteristic, so the Intelligent Dynamic Inspection equipment of corresponding calculated machine control must be arranged.
