[0036] In a preferred embodiment, the bypass valve 14 includes a valve core 141, a valve stem 142, a valve seat 143, and a second spring 144. The valve seat 143 is detachably connected to the bypass passage 13 and has a communication hole communicating with the original liquid chamber. The valve stem 142 is fixedly connected to the valve seat 143. The valve core 141 is sleeved on the outside of the valve stem 142 and slidably connected to the valve stem 142. One end of the second spring 144 is fixedly connected to the end of the valve stem 142 away from the valve seat 143, and the other end is fixedly connected to the valve core 141 to push the valve core 141 against the valve seat 143 to close the bypass passage 13. When the pressure in the original liquid chamber is greater than the preset pressure of the second spring 144, the second spring 144 can be compressed to make the valve core 141 move away from the valve seat 143, thereby connecting the original liquid chamber and the oil outlet passage 12 through the bypass passage 13. This design gives the bypass valve 14 good pressure control and on / off functions. Under normal pressure, the bypass passage 13 is closed to ensure that the oil passes through the filter element 3 for filtration; when the pressure is abnormal, the bypass passage 13 is opened in time to prevent the system pressure from being too high due to reasons such as the filter element 3 being blocked, so as to ensure the safety and normal operation of the hydraulic system.

[0037] In a preferred embodiment, the valve core 141 is used to contact the valve seat 143 with a conical surface. The conical surface design can improve the sealing and contact stability between the valve core 141 and the valve seat 143, and ensure the reliable closure of the bypass valve 14 under high pressure. At the same time, when opening, the valve core 141 can more easily overcome the spring force to achieve displacement and smoothly open the bypass passage 13.

Both the first gland and the second gland are sleeved on the outside of the valve stem 142 and are fixedly connected to both ends of the second spring 144. The first gland is used to abut against the bottom surface of the valve core 141, and the second gland is used to abut against the end of the valve stem 142 away from the valve seat 143. The first gland and the second gland play a role in limiting and protecting the second spring 144, ensuring that the spring functions within its normal operating range. At the same time, they improve the overall stability of the bypass valve 14 structure and prevent the spring from shifting or deforming due to vibration or other factors, thus affecting the normal operation of the bypass valve 14.

[0039] In a preferred embodiment, a fourth sealing ring and a fifth sealing ring are also included. A fourth mounting ring groove is provided on the inner side of the valve core 141.

A fifth mounting ring groove is provided on the outer side wall of the valve seat 143. The fifth sealing ring is used to be installed in the fifth mounting ring groove, and the outer edge of the fifth sealing ring protrudes from the fifth mounting ring groove and seals against the inner side wall of the bypass passage 13. The fourth and fifth sealing rings further enhance the sealing performance between the components of the bypass valve 14, prevent oil leakage in the bypass passage 13, ensure stable pressure control when the bypass valve 14 is working, and improve the working reliability of the bypass valve 14.

[0040] In a preferred embodiment, the filter head 1 further includes a mounting port 15 with an exhaust pressure test connector. The mounting port 15 with the exhaust pressure test connector is used to connect to the oil inlet circuit 11 to install the exhaust pressure test connector. The installation port with the exhaust pressure test connector facilitates the installation of the exhaust pressure test connector, which is used to detect the pressure of the oil inlet circuit and to discharge air from the pipeline. This allows the staff to monitor the operating status of the filter and hydraulic system in real time, promptly determine whether there are any abnormalities, and provide accurate data support for maintenance and troubleshooting.

[0041] In a preferred embodiment, the filter head 1 further includes a transmitter mounting station 16 for installing a transmitter. The transmitter mounting station 16 can install a transmitter that can promptly send a signal to the operator when the filter's operating parameters exceed the normal range, allowing for appropriate measures to be taken to avoid serious consequences due to equipment failure, thereby further improving the safety and reliability of the hydraulic system.
