Description
Technical Field

[0002] The compressor system collectively includes the compressor, oil station, gas cooler, and motor. Conventional dual-unit oil-cooled skid-mounted oil stations have the following problems:
[0003] 1) Some gas stations use a vertically stacked structure of two oil coolers, which requires a relatively large amount of space;
[0004] 2) The switching valve is a key component that determines the layout of the dual oil cooler. When the existing switching valve rotates the valve core, it can only switch between single-pass and dual-pass operation. It cannot adjust the flow area of the oil cooling end channel, and therefore cannot adjust the flow rate between single-pass and dual-pass operation. In addition, the linkage operation of the switching valve is not convenient enough. Utility Model Content

The system end channel is connected to the system connector. The end of the system end channel facing the system connector has a flared structure with a wider outer diameter and a narrower inner diameter. The outer diameter of the flared structure is larger than the diameter of the end of the system connector near the system end channel. The two oil-cooling end channels are connected to two oil-cooling connectors respectively. The diameter of the oil-cooling end channel is the same as the diameter of the corresponding oil-cooling connector. The two ends of the switching mechanism are connected to the valve balls of the two three-way valves respectively. At least one of the three-way valves has a connecting valve connected between the two oil-cooling connectors through a pipe. The connecting valve controls whether the two oil-cooling connectors are connected.
[0008] Furthermore, an oil pump is also installed on the skid frame.

[0010] Furthermore, an oil mist separator is also installed on the skid frame.
[0011] Furthermore, the switching mechanism includes a connecting rod and a handle, with both ends of the connecting rod connected to the valve balls of two three-way valves respectively, and the handle connected to the connecting rod.
[0012] Furthermore, the handle can be adjusted to its position in the connecting rod axial direction.
[0013] Furthermore, one end of the handle is locked to the connecting rod by a clamp structure.
[0014] Furthermore, the oil cooling joint is a flange pipe, and the connecting valve is connected to the flange pipe via a pipeline.
[0015] Furthermore, the system connector is located at the upper end of the valve body, the two oil-cooling connectors are located on the left and right sides of the valve body respectively, and the three-way groove is a T-shaped groove.

[0018] 2) The system end channel of the valve ball in the double switching valve is provided with a flared structure so that when the valve ball rotates at an appropriate angle, the flow cross section of the system end channel does not change, while the flow area of the oil cooling end channel is appropriately adjusted from single to double, thereby regulating the flow and optimizing the heat exchange between the double oil cooling and the system.
[0019] 3) The connecting rod in the double switching valve is designed as an adjustable switching connecting rod structure, which can adjust the position of the handle arbitrarily to meet the switching and adjustment at any angle and position.

The two oil-cooled end channels 1031 are respectively connected to the two oil-cooled connectors 102. The diameter of the oil-cooled end channel 1031 is the same as the diameter of the corresponding oil-cooled connector 102. The two ends of the switching mechanism are respectively connected to the valve balls 103 of the two three-way valves. At least one of the three-way valves has a connecting valve 104 connected between the two oil-cooled connectors 102 through a pipe. The connecting valve 104 controls whether the two oil-cooled connectors 102 are connected. The connecting valve 104 is preferably a manual valve, but a solenoid valve can also be used.

The oil pump 5 is connected to the system connector 101 of the double-switch valve 1 via a pipeline. After being cooled by the oil cooler 4, the system connector 101 of the other three-way valve of the double-switch valve 1 is connected to the temperature control valve via a pipeline, sending cold oil into the temperature control valve. The cold and hot oils are mixed at the set temperature of the temperature control valve, adjusting the temperature to a specific level. The outlet of the temperature control valve is connected to the oil filter 6 via a pipeline.
[0031] This utility model relates to a horizontally arranged dual-oil-cooled skid-mounted oil station, which is suitable for compressor systems that require dual oil cooling and have extremely limited installation and maintenance space. It is also suitable for single-oil-cooled users who need to optimize and upgrade at the lowest cost, thus contributing to the construction of a green, low-carbon, and circular economy system.

[0034] The working principle of this utility model gas station:
[0035] This gas station employs a horizontally arranged dual oil cooler system. The station's oil pump draws hot oil from the tank and delivers it to the dual oil cooler. After cooling, the oil flows through temperature control valves, oil filters, and other components to provide the system with lubricating oil within a specific temperature and pressure range. The dual oil coolers are arranged horizontally side-by-side. Connected to the station's piping via a switching valve, the dual oil coolers are installed at the same height as single oil coolers, meeting the requirements for uninterrupted online maintenance. The design incorporates the convenience and lowest cost of replacing single or dual oil coolers.
[0036] The development and design of this utility model of a double-unit switching valve enables the double-unit switching valve to possess switching and adjustment functions, freeing it from the structural limitations of double-unit oil coolers, minimizing installation space, and eliminating maintenance space requirements. This forms the basis for realizing online maintenance and switching of double-unit oil coolers. This utility model also reduces the overall cost of double-unit oil cooler equipment, meeting functional requirements while also considering user-friendly design principles, and is applicable to a wide range of environments.
[0037] This utility model of a double-switch valve adopts a newly designed three-way valve and a newly designed adjustable switching rod. The adjustable switching rod is connected to two three-way valves through a connecting structure, and the connecting valve is installed on two channels of the valve body. The valve ball adopts a T-slot, and the T-channel port (corresponding to the system pipe joint when double-switched) is designed with an enlarged hole. The valve ball is connected to the adjustable switching rod through a structure. When the switching rod rotates, it can realize two-position switching of oil-cooled single-way (the two channels of the T-slot form an L-shaped channel) and oil-cooled double-switch (the three channels of the T-slot are respectively connected to two oil coolers and system pipes), as well as a wide range of adjustment between single-way and double-way. The handle position of the adjustable switching rod can also be adjusted to any position between the two three-way valves. When switching to a single oil-cooled channel, the oil cooler is filled with oil through the connecting valve before switching or adjustment.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
