Abstract

The utility model relates to a valve in a pipeline system with gas or fluid working medium, in particular to an intelligent four-way reversing valve for the working medium flow direction transformation in the pipeline system. The utility model is realized in the way that a valve body (1) is adopted, a valve core axle (2) is provided in the valve body, a shape memory alloy spring (3) respectively provided at the two ends of the valve core axle is arranged in an end cover (4), and a PTC ceramic heater (5) is arranged outside the end cover (4), etc. to form the intelligent four-way reversing valve. The utility model has the advantages that the structure is simple, the price is low, after the valve core is displaced axially, the power can be cut off to save the power, the operation is reliable and the service life is long. The utility model is not only suitable for the pipeline system of an air-conditioner, but also suitable for an electric refrigerator, a water heater and so on, which brings an ideal fitting for scientific research and new product development.

Description

The intelligence four-way change-over valve

The utility model relates to the interior a kind of novel valve of pipe-line system of gas, liquid working medium, particularly the working medium in the pipe-line system is flowed to the intelligent four-way change-over valve of conversion.

The inventor declares " memory selector valve ", the patent No.: ZL 96205652.9 on February 28th, 1996.Because the development to " memory selector valve " inspires, the designer expects the application on air conditioner.The utility model intelligence four-way change-over valve can replace " the electromagnetism four-way change-over valve " that use present home and abroad on air conditioner.

The purpose of this utility model provides a kind of novel valve of using on air conditioner, its advantage: the relative electromagnetism four-way change-over valve of the utility model, and simple in structure, price is low, can cut off the power supply after poppet shaft is axially displaced, saves electric energy, the use of this valve is reliable, and the life-span is long.

The purpose of this utility model is achieved in that and adopts the marmem of new material to be made into screw type alloy spring, the spring expanded by heating, and the expansive force actuating valve mandrel of spring is axially displaced.It is to adopt the PTC ceramic heater that spring is heated, and heater adopts the ceramic plate of ring.

The concrete structure of model utility is provided by following enforcement and accompanying drawing thereof.

Fig. 1 is the total sectional drawing according to the concrete structure that the utility model proposes.

Describe in detail according to concrete structure and the working condition that the utility model proposes below in conjunction with Fig. 1.

The intelligent four-way change-over valve of the pipe-line system of air conditioner has a valve body (1), a poppet shaft (2) is arranged in the valve body, the two ends of poppet shaft respectively have a shape memory alloy spring (3) to place in the end cap (4), end cap (4) welds mutually with valve body (1), is provided with PTC ceramic heater (5) in the outside of end cap (4).

The working condition of this valve: behind a termination energize of valve, TPC ceramic heater work heating, heat will be passed to screw type alloy spring (3) by end cap (4), the alloy spring expanded by heating, the poppet shaft (2) that the expansive force of alloy spring promotes in the valve body is axially displaced, the displacement of poppet shaft (2) has changed five holes and 2 holes of poppet shaft (2) and the relative position of a groove of valve body (1), has also just changed the flow direction of working medium in the system.When poppet shaft (2) is moved only the other end by energising one end, just can cut off the power supply the saving electric energy.

After this valve the other end is connected power supply, PTC ceramic heater work heating, heat will be passed to screw type alloy spring (3) by end cap (4), the alloy spring expanded by heating, the poppet shaft (2) that the expansive force of alloy spring promotes in the valve body is axially displaced, the displacement of poppet shaft (2) has changed five holes and 2 holes of poppet shaft (2) and the relative position of a groove of valve body (1), has also just changed the flow direction of working medium in the system.

After an end of valve was connected power supply again, the same with aforesaid process, going round and beginning again changed the intrasystem working medium flow direction.

The utility model adopts the expansive force of shape memory alloy spring, and the novel valve as the displacement power of poppet shaft (2) is not only applicable in the pipe-line system of air conditioner, and also is suitable in the gas of refrigerator, water heater etc., liquid pipeline system.

This valve is new design, has brought desirable accessory to scientific research and new product development.
