Abstract
The utility model relates to a control device for a fuel gas regulation valve, which mainly utilizes a stepping motor to drive a control rod to shift linearly so as to accurately regulate and control the pressure and the flow rate of the valve and is particularly suitable to be used on a proportional valve of a water heater, wherein the stepping motor utilizes a pulse control principle of magnetic pole exchange of an electromagnetic coil to drive a multipole magnetic ring so as to accurately drive the control rod to shift linearly, and thus, the pressure and the flow rate at an outlet of the valve can be controlled more accurately. The control device is beneficial for carrying out more rapid and accurate regulation on the valve corresponding to the pressures and the flow rates of different fuel gases.
Description
Technical field
The utility model relates to a kind of valve control technique of combustion gas, refers to that especially a kind of valve that can make is corresponding to the pressure of different combustion gas kinds and traffic demand and the control gear of adjusting and controlling.
Background technique
In combustion gas tool or combustion gas conductive device, utilize various valves come to combustion gas block, flow control, be a kind of necessary means of implementing so that the pressure of combustion gas, flow control are more easy, or for open and close, the usefulness of safety blocking-up.
Because the kind difference of combustion gas, the preservation that it presents, transmission and delivery pressure and inequality, for example rock gas promptly presents different delivery pressures with the barreled liquefied petroleum gas (LPG), and many valves that are applied to combustion gas can utilize gaseous-pressure to carry out flow control or safety control on the implementation, so in response to different combustion gas kinds, then must adopt preset pressure when making the combustion gas tool, the valve that flow is different, so that the enough normal operations of combustion gas prodigiosin, perhaps in the combustion gas tool, install the valve that is available for users to adjust working pressure and flow, make the combustion gas prodigiosin carry out related setting in response to different combustion gas.
Yet, the pressure of commercially available combustion gas tool related valve, the adjustment means of flow control, utilize calutron directly to promote a controlling rod mostly and carry out linear displacement, and utilize the means that change the supply current size to change the thrust of calutron, so that the compressing force of the spring of control valve outlet pressure and flow changes, and then valve can be adjusted corresponding to the pressure of different combustion gas kinds and traffic demand.
The existing enforcement means of this kind, the moment that starts except calutron impacts to valve easily, also easy instability because of the aging of calutron and thrust output usefulness makes spring pre-load compression amount be not so good as to expect, and pressure and the coarse problem of flow control take place.
In view of this, model utility designer is at valve control the carrying out research and discussion of gas valve, and then make valve export pressure and flow can obtain more accurately control, being beneficial to valve can adjust corresponding to the pressure of different combustion gas kinds and traffic demand.
Summary of the invention
The purpose of this utility model is providing a kind of control structure that can accurately adjust valve export pressure and flow.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of gas control valve control gear comprises a pedestal, a controlling rod and a stepper motor, it is characterized in that:
This pedestal has a non-circular perforation, this controlling rod one end is provided with and bores a hole corresponding and penetrate the guide posts that limits the controlling rod linear displacement in this perforation, described guide posts end contacts at one and is used for making valve to keep the spring of normally off, and the other end of controlling rod has a screw part again;
Described stepper motor has multi-pole magnet-ring and coil block of controlling multi-pole magnet-ring deflection with pulse control magnetic force output that a nut portion, that is screwed together in screw part drives this nut portion rotation.
Wherein: this controlling rod structure that is formed in one.
Wherein: described valve is the pressure differential valve with pressure reduction diaphragm.
Wherein: this perforation and cylinder are the polygonals that matches.
When coil block drives the multi-pole magnet-ring rotation, can make nut portion can obtain smart adjustment and control, and then the drive controlling bar carries out linear displacement and changes the compressing force of aforementioned spring, even if when valve is subjected to bigger pressure or impact force action, controlling rod still can rely on screw part to remain on original predeterminated position with cooperating of nut portion, can not be offset, allow valve be remained on best pressure and flow control state.
During enforcement, described controlling rod can be the modularization manufacturing and makes that guide posts is the end that is assembled in controlling rod, or this controlling rod is formed in one structure to save manufacturing process and cost.
Described valve is the pressure differential valve with pressure reduction diaphragm, accurately controls the position of diaphragm connecting rod to utilize aforementioned stepper motor, pedestal and controlling rod, makes the back pressure of pressure reduction diaphragm be kept stable.
Described perforation and cylinder are the polygonal moulding that matches, and to prevent controlling rod with respect to the perforation rotation, guaranteeing can the push lever linear displacement when multi-pole magnet-ring drives the rotation of nut portion.
Compared to prior art, the utility model utilizes the pulse control principle of electromagnetic coil magnetic pole exchange to drive a multi-pole magnet-ring, so that stepper motor can drive the controlling rod linear displacement accurately, and then make valve export pressure and flow obtain control more accurately, so valve can be adjusted with traffic demand corresponding to the pressure of different combustion gas kinds, the setting that makes valve with adjust more accurate, rapid and convenient.
