Detailed Description
The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.
The electromagnetic valve with the short throttling pipe as shown in fig. 1 to 3 is used in the heat pump system as shown in fig. 1, the short throttling pipe and the electromagnetic valve are arranged in parallel in the system, and the short throttling pipe and the electromagnetic valve are matched together to realize the heating and cooling mode functions of the heat pump system, in fig. 1, the short throttling pipe and the electromagnetic valve are separately arranged, so that the design usually brings a large number of pipeline design and installation procedures, has a lot of limitations, is inconvenient to use, and is easy to cause problems of leakage and the like;
in order to make the system simpler to use and avoid laying the pipeline, the electromagnetic valve structure of the integrated cut-off short pipe is adopted as shown in fig. 2 and 3, wherein the electromagnetic valve structure comprises a valve body 1, a valve cover 2 arranged on the valve body 1 and an electromagnetic control part 3 arranged on the valve cover 2, and a junction box 4 is arranged on one side of the electromagnetic control part 3; a liquid inlet cavity 11 is arranged on one side of the valve body 1, a liquid outlet cavity 12 is arranged on the other side of the valve body 1, a valve port 13 is arranged between the liquid inlet cavity 11 and the liquid outlet cavity 12 in the valve body 1, a valve core 5 is closely arranged on the valve port 13, the top of the valve core 5 is connected with a movable iron core 6, and an electromagnetic control part 3 is sleeved on the top of the movable iron core 6; when the electromagnetic control part is electrified to control the movable iron core to move up and down, the movable iron core drives the valve core to move up and down, so that the liquid inlet cavity and the liquid outlet cavity are communicated; a throttling short pipe 7 is also arranged on the valve body 1 for separating the liquid inlet cavity 11 and the liquid outlet cavity 12;
in order to realize the structural reliability, the throttling short pipe 7 adopts the simplest single pipe, namely a single bidirectional throttling short pipe, and the short pipe does not adopt a structure of a one-way valve, so that the production cost is reduced, and the welded junction and the leakage hidden danger are reduced; in addition, the vibration noise of the check valve can be avoided;
in addition, because the particularity of the solenoid valve and the short throttling pipe is that the cleaning degree of the medium is very high, in order to prevent impurities from entering the solenoid valve and blocking the short throttling pipe to influence the sealing reliability of the main valve element, a filter screen or a Y-shaped filter can be arranged at the front end of the solenoid valve, and in order to reduce extra connecting structures and improve the reliability of the device, the filter screen 111 is preferably fixedly arranged in the liquid inlet cavity 11.
When the heat pump system is in a refrigeration mode, the compressor is started to compress a refrigerant into high-temperature and high-pressure gas, the high-temperature and high-pressure gas enters the condenser, the condenser cools the high-temperature and high-pressure gas into high-temperature and high-pressure liquid, then the liquid flows through the electromagnetic valve with the short throttling pipe, at the moment, the electromagnetic control part of the electromagnetic valve is electrified to enable the movable iron core to move upwards, so that the valve core is separated from the valve port, and at the moment, the refrigerant in the liquid inlet cavity directly flows through the valve port to enter the liquid outlet;
when the heat pump system is in a heating mode, an electromagnetic control part on the electromagnetic valve is in a closed state, at the moment, the valve core is in close contact with the valve port, and a refrigerant in the liquid inlet cavity passes through the throttling short pipe under high pressure and is changed into a gas-liquid two-phase state from a liquid phase under the throttling and pressure reducing action of the throttling short pipe; and then into the external heat exchanger.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
