Abstract
The utility model discloses a miniature pressure controller comprising a compressive deformation component arranged in an air box, and a switch component controlled by the deformation of the compressive deformation component to switch on and switch off, wherein the compressive deformation component comprises a corrugated pipe and a spring, wherein one end of the corrugated pipe is fixedly connected to a joint of the air box and the corrugated pipe can deform along with pressure change. The spring is butted with the other end of the corrugated pipe; the switch component is a momentary contact switch component. The utility model has the advantages of accuracy and sensitivity improvement and failure possibility reduction of a product; when system pressure rises or reduces, the spring and the corrugated pipe generate elongated or contracted deformation, a switch is driven to act by a transmissions part to switch off or switch on a control circuit, and accordingly, the purpose of two-step control for medium pressure is achieved. The utility model is suitable for a pressure control system in refrigeration industry, boiler industry, clothes machine industry, welding machine industry, water treatment industry, etc.
Description
Technical field
The utility model relates to a kind of automatic control and protective device, particularly a kind of micro pressure controller that changes and make circuit disconnection or closure along with the pressure in the system.
Background technology
Mostly conventional small pressure controller is to adopt bellows or diaphragm and rubber seal as the gas tank parts.The sealing of bellows is better, but deflection is less, and the adjustable range of pressure is narrow, the bellows that the system of different pressures can only whole replacing different applications, and cost is higher.Diaphragm and rubber seal coil structures, be subjected to the influence of variations in temperature and steam easily and wear out, corrode in operational environment, thereby cause pressure controller to leak easily or lost efficacy, the deflection of diaphragm is little simultaneously, therefore the sensitivity of product is not high, and the adjustable range of pressure is narrow.Conventional simultaneously small pressure controller adopts touch switch more, and pressure slowly raises, and when pressure was in critical condition, soon Jie Chu switch contact was easy to generate electric arc, thereby main frame is damaged.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of micro pressure controller, its reliability height, and the pressure adjustable range is big, and is safe in utilization.
The purpose of this utility model is achieved in that a kind of micro pressure controller, comprise the compressive deformation parts that are built in gas tank, and the switch block of controlling folding by the deformation of compressive deformation parts, it is characterized in that: described compressive deformation parts comprise that an end is fixed in the bellows that can be out of shape with air pressure change of gas tank joint and the spring that offsets with the bellows other end, and switch block is a wink dynamic formula switch block.
Described bellows is welded in gas tank joint inboard.
Described wink, the dynamic formula switch block comprised push rod, contact sensitive switch and the bottom bullet face that drives push rod and compressive deformation parts interlock.
Be provided with the adjusting parts of a scalable bellows rock deformation pressure between described spring upper end and the gas tank inwall.
Be provided with driving member between described compressive deformation parts and the switch block.
The utility model is by adopting the big bellows of deflection, product accuracy and sensitivity are improved, and greatly reduce the possibility of product failure, when the pressure of system rises or descends, the distortion that the corresponding compression spring of controller and bellows produce elongation or shrink, move by the driving member pull switch, cut off or connect control circuit, thereby reach purpose, be applicable to the control pressurer system of industries such as refrigeration, boiler, garment machinery, electroplating equipment wielding machine, water treatment the pressure medium on-off control.
Description of drawings
Fig. 1 is a cut-away view of the present utility model.
Embodiment
The utility model is a kind of micro pressure controller, as shown in Figure 1, comprises gas tank 1, compressive deformation parts, switch block 6 etc.The compressive deformation parts place in the gas tank 1, comprise bellows 2 and spring 3.Bellows 2 lower ends are welded in gas tank joint inboard, and welding ends communicates with the gas tank joint, can be out of shape with the air pressure change of system.As the gas tank parts, and adopt the soldering tin technique welding with copper corrugated pipe and copper sleeve, thereby solved existing diaphragm and the rubber seal coil structures is subjected to the influence of temperature and steam and causes problem aging and corrosion in operational environment.The upper end of spring 3 lower ends and bellows 2 offsets, and its effect is the rock deformation pressure of control bellows 2 and bellows 2 is resetted.Be the control rock deformation pressure in the prior art, must adopt the different bellows or the diaphragm of different-thickness, the production cost height, technical difficulty is big.And in the utility model, can adopt different flexible springs to control, also can between spring 3 upper ends and gas tank 1 inwall, establish the adjusting parts 5 of a scalable bellows 2 rock deformation pressures.Regulate parts 5 and can adopt an adjusting nut, revolve and save in gas tank 1 inwall, regulate its height in gas tank 1 by rotation and can compress spring 3 to some extent, make 3 pairs of bellowss 2 of spring apply different pressure, it is the rock deformation pressure of scalable bellows 2, very convenient, adjustable range is wide, between 0~3.0Mpa even higher.Switch block 6 is a wink dynamic formula switch block, comprises push rod 61, contact sensitive switch 62 and the bottom bullet face 63 that drives push rod 61 and compressive deformation parts interlock.Be provided with driving member between compressive deformation parts and switch block 6, for being socketed on the drive link 4 in the spring 3, one end and bellows offset, and the bottom bullet face 63 of the other end and switch block 6 offsets, and drives both interlocks.
During use; vertically be installed on gas tank joint of the present utility model on the instrument board; be communicated with system pressure; when the pressure of system rises or descends; control circuit is cut off or connected to the distortion that the corresponding compression spring of controller and bellows produce elongation or shrink by the action of driving member pull switch; switch is disconnected rapidly under critical condition or close, thereby realized automatic control and protection.
