Description

Technical Field

[0001] The utility model relates to the technical field of reversing valves, in particular to a four-way reversing valve. Background Art

[0002] The four-way reversing valve is mainly composed of a main valve, a pilot valve and an electromagnetic coil. When working, the main valve is switched through the joint action of the electromagnetic coil and the pilot valve to achieve the purpose of switching the flow direction of the fluid, so that the heat exchange system can switch between two working states to achieve the dual-purpose working purpose of cooling in summer and heating in winter. Most of the existing four-way reversing valves use metal brackets, which are not only simple in process but also heavy in weight, and the fixed connection effect is not good. Severe vibration will occur during operation, affecting the overall performance of the four-way reversing valve. Therefore, we propose a four-way reversing valve pipeline fixing structure to solve the above problems. Utility Model Content

[0003] In order to overcome the problem that most existing four-way reversing valves use metal brackets, which are not only simple in process but also heavy in weight, have poor fixed connection effects, and produce severe vibrations during operation, thus affecting the overall performance of the four-way reversing valve.

[0004] The technical solution of the utility model is: a pipeline fixing structure of a four-way reversing valve, comprising a valve body, a connecting module, an installation pipeline, a fixing module and an installation module; four groups of connecting modules for connecting the installation pipeline are installed around the outside of the valve body, an installation pipeline for changing the flow direction of the fluid is installed at one end of the connecting module away from the valve body, a fixing module for further fixing the connecting module and the installation pipeline is sleeved on the outside of the connection between the connecting module and the installation pipeline, and four groups of installation modules for finally fixing the connecting module and the installation pipeline and fixedly connected to the connecting module are installed around the outside of the installation pipeline.

[0005] Preferably, when the branch pipe and the mounting pipeline are further installed, the first rotating shaft drives the telescopic sleeve and the mounting pipeline to rotate to a suitable angle through the arc groove, and then the telescopic column drives the L-shaped mounting plate to move along the telescopic sleeve by adjusting the positioning bolt until the L-shaped mounting plate is close to the connecting ring plate, and at the same time, the L-shaped mounting plate is rotated to be parallel to the connecting ring plate through the second rotating shaft and the telescopic column, and then the mounting bolt drives the L-shaped mounting plate and the connecting ring plate to be fixedly connected through the mounting hole, and finally the positioning bolt is tightened to fix the telescopic column along the moving length of the telescopic sleeve, thereby finally fixing the branch pipe and the mounting pipeline.

[0006] Preferably, the connecting module includes a connecting ring plate, a branch pipe and a clamping column. The connecting ring plate is sleeved on the outside of the branch pipe. A plurality of sets of clamping columns are installed around the edge of one side of the branch pipe away from the valve body. The connecting ring plate is provided with mounting holes for fixing the connecting installation module. The mounting holes are convenient for installation with mounting bolts. The clamping column passes through the clamping groove to drive the branch pipe to be initially fixedly connected with the installation pipeline.

[0007] Preferably, four groups of arc grooves for installing the installation module are opened around the outside of the installation pipeline, and a clamping groove for the clamping column to pass through is opened on one side of the installation pipeline close to the connecting module corresponding to the clamping column. The arc groove facilitates the installation of the first rotating shaft, and the clamping groove facilitates the passage of the clamping column.

[0008] Preferably, the fixed module includes a connecting shaft, an arc-shaped clamping plate, an arc-shaped rubber pad, a positioning column and a nut. The arc-shaped clamping plates are symmetrically installed on both sides of the connecting shaft. The arc-shaped clamping plates are rotatably connected to the connecting shaft. An arc-shaped rubber pad is installed on the inner side of the arc-shaped clamping plate to increase the sealing performance to prevent fluid leakage. After the branch pipe and the installation pipeline are initially fixed, the arc-shaped clamping plate is rotated along the connecting shaft until the arc-shaped rubber pad completely fits the connection between the branch pipe and the installation pipeline, thereby increasing the sealing performance to prevent fluid leakage.

[0009] Preferably, positioning columns are passed through the upper ends of the two sets of arc-shaped clamping plates, and two sets of nuts are laterally sleeved on the outside of the positioning columns. After the fitting is completed, the positioning columns pass through the arc-shaped clamping plates and are tightened and fixed by nuts, thereby achieving further fixed connection.

[0010] Preferably, the installation module includes a first rotating shaft, a telescopic sleeve, a positioning bolt, a telescopic column, a second rotating shaft, an L-shaped mounting plate and a mounting bolt. The first rotating shaft is installed at one end of the telescopic sleeve. The first rotating shaft drives the telescopic sleeve to rotate and connect with the mounting pipeline through an arc groove. A telescopic column is installed inside the telescopic sleeve. After the branch pipe and the mounting pipeline are further installed, the first rotating shaft drives the telescopic sleeve and the mounting pipeline to rotate to a suitable angle through the arc groove to improve flexibility.

[0011] Preferably, a positioning bolt is provided at the connection between the telescopic sleeve and the telescopic column, a second rotating shaft is installed at one end of the telescopic column, the L-shaped mounting plate is rotatably connected to the telescopic column through the second rotating shaft, a mounting bolt is installed in the middle of the L-shaped mounting plate, and the mounting bolt drives the L-shaped mounting plate and the connecting ring plate to be fixedly connected through the mounting hole, and then by adjusting the positioning bolt, the telescopic column drives the L-shaped mounting plate to move along the telescopic sleeve until the L-shaped mounting plate is close to the connecting ring plate, and at the same time, the L-shaped mounting plate is rotated with the telescopic column through the second rotating shaft to be parallel to the connecting ring plate, and then the mounting bolt drives the L-shaped mounting plate and the connecting ring plate to be fixedly connected through the mounting hole, and finally the positioning bolt is tightened to fix the length of the telescopic column moving along the telescopic sleeve, thereby finally fixing the branch pipe and the installation pipeline.

[0012] Beneficial effects of the utility model:

[0013] 1. In the past, most four-way reversing valves used metal brackets, which not only had simple processes but also had heavy weight, and the fixed connection effect was not good. During operation, severe vibrations would occur, affecting the overall performance of the four-way reversing valve. In contrast, the clamping column first passes through the clamping groove to drive the branch pipe and the installation pipeline to make a preliminary fixed connection, and then the arc-shaped clamping plate rotates along the connecting axis until the arc-shaped rubber pad completely fits the connection between the branch pipe and the installation pipeline. After the fitting is completed, the positioning column passes through the arc-shaped clamping plate and is tightened and fixed by a nut, thereby making a further fixed connection.

[0014] 2. After the branch pipe and the installation pipeline are further installed, the first rotating shaft drives the telescopic sleeve and the installation pipeline to rotate to a suitable angle through the arc groove, and then the telescopic column drives the L-shaped installation plate to move along the telescopic sleeve by adjusting the positioning bolt until the L-shaped installation plate is close to the connecting ring plate. At the same time, the L-shaped installation plate is rotated to be parallel to the connecting ring plate through the second rotating shaft and the telescopic column, and then the installation bolt drives the L-shaped installation plate and the connecting ring plate to be fixedly connected through the installation hole. Finally, the positioning bolt is tightened to fix the telescopic column along the moving length of the telescopic sleeve, thereby finally fixing the branch pipe and the installation pipeline.
