Description

Technical Field

[0001] The utility model belongs to the technical field of air source heat pumps, and particularly relates to an energy-saving four-way valve for an air source heat pump. Background Technique

[0002] An air source heat pump is a device that uses the heat in the outside air for heating and cooling. Its working principle is based on the circulation of refrigerant between the evaporator and the condenser. Through the work of the compressor, low-temperature heat is absorbed, compressed by the compressor and then becomes high-temperature heat energy, and then released into indoor water or air to achieve heating; in the cooling mode, this process is reversed, and the indoor heat is absorbed and then released into the outside air through the cycle.

[0003] In a ground source heat pump system, the four-way valve is a key component responsible for switching the refrigerant flow direction to achieve the cooling or heating mode. However, in actual applications, the accidental opening or closing of the four-way valve due to accidental touch may cause unstable system operation and even equipment damage. This situation limits the reliability of the four-way valve in actual applications, especially in occasions that require high stability and long-term unattended operation. Therefore, it is necessary to improve the design of the four-way valve to prevent misoperation and ensure the safe operation of the ground source heat pump system. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an energy-saving four-way valve for an air source heat pump to solve the problem that the accidental opening or closing of the four-way valve due to accidental touch in the above background technique may cause unstable system operation and even equipment damage, which limits the reliability of the four-way valve in actual applications, especially in occasions that require high stability and long-term unattended operation.

[0005] To achieve the above object, the utility model provides the following technical solution: An energy-saving four-way valve for an air source heat pump, including a valve body, a four-way pipe is installed inside the valve body, a mounting seat is fixedly connected to the upper surface of the valve body, a valve rod is rotatably connected through the middle part of the inside of the mounting seat, both ends of the upper surface of the mounting seat are fixedly connected with fixing blocks, a telescopic groove is opened inside the fixing blocks, a clamping block is slidably connected to the upper end inside the telescopic groove, a spring structure is arranged between the clamping block and the bottom end inside the telescopic groove, there are two clamping blocks, a rotating disk is fixedly connected to the side surface of the valve rod, and a plurality of positioning holes are penetrated through the surface of the rotating disk.

[0006] Preferably, the mounting seat is fixedly installed on the upper surface of the valve body by bolts.

[0007] Preferably, a handwheel is fixedly connected to the upper surface of the valve rod.

[0008] Preferably, a handle is fixedly connected to one side surface of the clamping block.

[0009] Preferably, the cross-section of the clamping block is a right-angled triangle structure.

[0010] Preferably, a sliding groove is formed on the lower surface of the rotating disc.

[0011] Preferably, the valve body is made of stainless steel.

[0012] Compared with the prior art, the present utility model provides an energy-saving four-way valve for an air source heat pump, which has the following beneficial effects:

[0013] 1. Through the structures such as the clamping block and the positioning hole provided in the present utility model, when it is necessary to rotate the valve stem clockwise, the left clamping block is pressed downward through the handle, and the handle is released after the valve stem rotation is completed. When it is necessary to rotate the valve stem counterclockwise, the right clamping block is pressed downward through the handle, and the two clamping blocks on the left and right sides are ejected upward by the spring structure and clamped inside the positioning hole, realizing the limitation of the rotation angle of the rotating disc, thereby ensuring that the valve stem of the four-way valve will not be accidentally touched, effectively avoiding the accidental opening or closing of the four-way valve caused by accidental touch, which may cause unstable system operation and even equipment damage. This situation limits the reliability of the four-way valve in practical applications, especially in occasions that require high stability and long-term unattended operation;

[0014] 2. By adopting a valve body made of stainless steel in the present utility model, the energy-saving function of the four-way valve of the air source heat pump is realized, and the valve body has excellent corrosion resistance and can resist the erosion of various chemical substances that may be encountered in the heat pump system, such as chlorides, sulfides, etc. This means that the four-way valve is not easily damaged during long-term use, reducing the maintenance and replacement frequency caused by corrosion, thereby saving resources and energy.

At this time, the left clamping block 12 pops up upward under the action of the spring structure 14 and is stuck inside the positioning hole 8 to limit the rotation angle of the rotating disk 7 and prevent the valve stem 5 from being accidentally touched. When it is necessary to rotate the valve stem 5 counterclockwise, the user presses the right clamping block 12 downward through the handle 13, holds the handwheel 6 and rotates the valve stem 5 counterclockwise, and then releases the handle 13 after rotation. Similarly, the right clamping block 12 pops up upward under the action of the spring structure 14 and is stuck inside the positioning hole 8 to limit the rotation angle of the rotating disk 7. Through the above operations, the user realizes precise control of the air source heat pump four-way valve, avoids accidental opening or closing caused by accidental touch, and ensures high stability and reliability of the system operation. Especially in occasions where there is no one on duty for a long time, this structural design greatly improves the safety of the four-way valve in practical applications.
