[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1 The embodiment of the utility model provides a technical solution: a multiple small bypass valve integrated end cover device for a wind power gearbox filter element, comprising a device body 1, the device body 1 comprising an end cover body 2, a small bypass valve mechanism 3 and an end cover cover plate 4, the small bypass valve mechanism 3 is provided with a plurality of groups, the plurality of groups of the small bypass valve mechanisms 3 are annularly equidistantly installed in the end cover body 2, the end cover cover plate 4 is fixed on the top of the end cover body 2, and the end cover cover plate 4 is located on the top of the plurality of groups of small bypass valve mechanisms 3;
[0019] The problem is solved, the small bypass valve mechanism 3 includes a bypass valve seat 5, a spring 6 and a valve core 7, the spring 6 is sleeved on the outside of the valve core 7, and the bypass valve seat 5 is installed on the outside of the spring 6. Through a number of small bypass mechanisms 3, a single failure can be prevented. Further, when the filter element is blocked, the pressure difference is too large, causing the filter element to be crushed.
[0020] Furthermore, the end cover body 2 is a disc-shaped structure, and a plurality of groups of mounting grooves 9 distributed in a ring manner are opened in the end cover body 2. The mounting grooves 9 are a cylindrical structure. The mounting grooves 9 in the end cover body 2 are for facilitating the installation of the small bypass valve mechanism 3.
[0021] Differently, a sealing member 8 is installed at the bottom of the bypass valve seat 5. The sealing member 8 is in a circular ring structure and is made of rubber. The sealing member 8 at the bottom of the bypass valve seat 5 can improve the sealing performance and prevent leakage.
[0022] Effectively, the bypass valve seat 5 and the valve core 7 are both made of stainless steel. The bypass valve seat 5 and the valve core 7 are made of stainless steel, which can effectively improve the wear resistance of the bypass valve seat 5 and the valve core 7 and increase the service life. They also have anti-corrosion function, which can prevent the bypass valve seat 5 and the valve core 7 from being corroded.
[0023] Working principle: During operation, multiple small bypass valve mechanisms 3 are evenly distributed in the end cover body 2. Each small bypass valve mechanism 3 includes a bypass valve seat 5, a valve core 7 and a spring 6. The valve core 7 and the bypass valve seat 5 are sealed and matched to form a closed state. When the filter element body is blocked, the pressure difference reaches a certain value, the valve core 7 overcomes the spring force under the action of oil pressure, the small bypass valve opens, and the oil flows out through the small bypass valve mechanism 3 to realize the bypass function. The uniform distribution of multiple small bypass valve mechanisms 3 also improves the uniformity and stability of the bypass effect. At the same time, the opening pressure of the small bypass valve mechanism 3 can be adjusted according to actual needs to meet the bypass requirements under different working conditions.
[0024] The utility model comprises 1, a device body; 2, an end cover body; 3, a small bypass valve mechanism; 4, an end cover plate; 5, a bypass valve seat; 6, a spring; 7, a valve core; 8, a sealing member; 9, a mounting groove. All the components are universal standard components or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. The utility model solves the problem that the existing filter element design usually only sets a large bypass valve on the filter element end cover, or integrates a large bypass valve on the filter cover. When the filter element is blocked, the bypass valve may be stuck due to factors such as spring manufacturing process defects or other factors. The bypass valve cannot be opened in time and effectively to play a bypass role, and the lubrication filter elements are relatively large. The flow rate that needs to pass through a single bypass valve needs to be large, and the opening area of the bypass valve needs to be large. Then, the preload force of the spring required for a single bypass valve is very large, which is not conducive to product assembly. The utility model can integrate an end cover device through a plurality of small bypass valves through the combination of the above-mentioned components. The structure is simple and has strong applicability. The opening pressure of the bypass valve can be adjusted according to actual conditions by adjusting the spring parameters. The number of bypass valves can also be adjusted according to actual flow requirements. Only the end cover body needs to be adjusted, which greatly reduces the manufacturing cost.
[0025] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
