Description

A kind of temperature control valve

Technical field

The utility model relates to a kind ofly can regulate flow, especially can regulate the temperature control valve of flow by the variation of ambient temperature automatically.It belongs to the HVAC valve and makes the field.

Background technique

Present known temperature control valve is the expansion that is produced because of temperature variation by the metal thermometer bulb in the valve handle or shrinks the unlatching of control valve or close, thereby the flow size of control media fluid influences ambient temperature.Its working method is: the metal thermometer bulb drives depression bar because of expansion or the contraction that temperature variation produces when temperature change, depression bar promotes piston, piston is blocked or the Open valve water intake, make valve closing or unlatching, because the sealing of depression bar is O type circle sealing on the pressured bar, moving up and down of depression bar makes the quick abrasion of O type circle many, leaks in case wearing and tearing will form, and causes disaster.

Summary of the invention

The purpose of this utility model is: solve original temperature control valve and damage inefficacy easily because of the wearing and tearing of O type circle, cause medium to leak outside and form the problem of disaster.The utility model provides a kind of magnetic coupling type temperature control valve, and this valve does not have machinery outer logical, thoroughly avoids damaging inefficacy easily because of the wearing and tearing of O type circle, causes medium to leak outside and forms the problem of disaster.

For reaching the purpose of this utility model, the used technological scheme of the utility model technical solution problem is: the inner magnetic core of temperature control valve piston sleeve is made some groups, and the magnet outside the piston sleeve is corresponding with it, forms the magnetic circuit of a plurality of mutual closures.Directly control the center osculum of big piston assembly in conjunction with inner magnetic core, direct promotion continuous motion stem is done and is moved up and down when thermometer bulb temperature influence generation deformation, and magnet is together moved up and down, under the magnetic force of outer magnet, inner magnetic core is moved up and down together, because the inner magnetic core assembly is directly controlled the water inlet at big piston assembly center and is formed big piston assembly pressure reduction up and down, at big piston up and down under the active force of pressure reduction, the big piston assembly is moved up or down, open or close valve, because the location-controlled of inner magnetic core assembly is in the position of outer magnet, and the location-controlled of outer magnet is in thermometer bulb, the controlled again and Temperature Influence of thermometer bulb, therefore outer magnet under a temperature, the position of inner magnetic core assembly is consistent relatively, water-outlet quantity is relatively stable, the thermometer bulb temperature influence begins to shrink, Returnning spring upwards promotes continuous motion stem and moves up, the drive outer magnet moves up, the inner magnetic core assembly is moved up, big piston moves up under the thrust of hydraulic pressure simultaneously, and the current quantitative change of valve is big; Otherwise, thermometer bulb begins to expand under Temperature Influence, promotes continuous motion stem and moves down, and drives the outer magnet assembly and moves down, the inner magnetic core assembly of piston sleeve moves under the effect of magnetic force, slowly big piston assembly osculum is stopped up, valve water flow diminishes, the thermometer bulb temperature influence continues to move down, because of osculum stops up, intake pressure continues to increase, and the big piston assembly is closed valve outlet, the anhydrous outflow of valve.During rotatable handle, because of using with the lifting cover, handle is threaded, the lifting cover moves the drive continuous motion stem and moves up and down, thereby make that manual rotatable handle just can the controlled water flow amount, during handle with sleeve, change is to the pressure and the deformation space of thermometer bulb, so thermometer bulb is subjected to the spacing control of handle, makes temperature constant in relative space.

The beneficial effects of the utility model are: utilize outer magnet to make valve controlled by magnetic force control inner magnetic core assembly, there is not machinery outer logical, accomplish totally-enclosed, overcome the possibility that medium leaks, appropriate design by external magnet assembly and a plurality of magnets of inner magnetic core assembly, form the magnetic circuit of a plurality of closures, greatly increased magnetic force.Whole valve simple and reasonable.
