Technical Field
The invention relates to the technical field of internal combustion engine machinery, in particular to a bypass valve protection structure.
Background
The bypass valve for the general engine is integrated in the oil duct, and because the distance between the steel ball and the pressure relief hole is generally relatively short, when the system pressure is abnormally increased, the steel ball can fall into the pressure relief hole after moving to the position of the pressure relief hole, so that the bypass valve is invalid.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
Disclosure of Invention
The invention aims to provide a bypass valve protection structure which is simple and reasonable in structure and can effectively avoid failure of a bypass valve.
In order to achieve the above object, the present invention provides a bypass valve protection structure integrated in a bottom plate of an oil cooler, the bypass valve protection structure including: the device comprises a first oil duct, a second oil duct, a steel ball, a pressure relief hole and a bracket. The first oil duct is arranged in the bottom plate; the second oil duct is arranged in the bottom plate, and one end of the second oil duct is connected with one end of the first oil duct; the steel ball is arranged in the first oil duct, and the steel ball is positioned in one end of the first oil duct, which is close to the second oil duct; the pressure relief hole is arranged in the second oil duct; the bracket is arranged on the pressure relief hole and is used for preventing the steel ball from falling into the pressure relief hole; when the oil pressure of the first oil duct is greater than that of the second oil duct, the oil pushes the steel ball to move towards the second oil duct, so that the first oil duct is communicated with the second oil duct, and pressure is relieved through the pressure relief hole.
In a preferred embodiment, the diameter of the first oil passage is smaller than the diameter of the second oil passage.
In a preferred embodiment, the bypass valve protecting structure further comprises a plug screw disposed on the other end of the second oil passage, and the plug screw is used for blocking the second oil passage.
In a preferred embodiment, the bypass valve protecting structure further includes a spring disposed in the second oil passage, and one end of the spring is in contact with the steel ball.
In a preferred embodiment, the carrier is cast.
Compared with the prior art, the bypass valve protection structure is simple and reasonable in structure, low in cost, long in service life and high in practicability, and failure of the bypass valve can be effectively avoided.
Drawings
Fig. 1 is a schematic front view of a bypass valve protecting structure according to an embodiment of the present invention.
The main reference numerals illustrate:
the device comprises a base plate 1, a first oil duct 2, a second oil duct 3, a steel ball 4, a pressure relief hole 5, a bracket 6, a spring 7 and a screw plug 8.
Description of the embodiments
The following detailed description of embodiments of the invention is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
As shown in fig. 1, fig. 1 is a schematic front view of a bypass valve protecting structure according to an embodiment of the present invention.
According to a preferred embodiment of the present invention, a bypass valve protection structure integrated in a bottom plate 1 of an oil cooler, the bypass valve protection structure includes: the device comprises a first oil duct 2, a second oil duct 3, a steel ball 4, a pressure relief hole 5 and a bracket 6. The first oil duct 2 is arranged in the bottom plate 1; the second oil duct 3 is arranged in the bottom plate 1, and one end of the second oil duct 3 is connected with one end of the first oil duct 2; the steel ball 4 is arranged in the first oil duct 2, and the steel ball 4 is positioned in one end of the first oil duct 2 close to the second oil duct 3; the pressure relief hole 5 is provided with a second oil duct 3; the bracket 6 is arranged on the pressure relief hole 5, and the bracket 6 is used for preventing the steel ball 4 from falling into the pressure relief hole 5; when the oil pressure of the first oil duct 2 is greater than that of the second oil duct 3, the oil pushes the steel ball 4 to move towards the second oil duct 3, so that the first oil duct 2 is communicated with the second oil duct 3, and pressure is relieved through the pressure relief hole 5.
In a preferred embodiment, the diameter of the first oil passage 2 is smaller than the diameter of the second oil passage 3; the bypass valve protection structure further comprises a plug screw 8 arranged at the other end of the second oil duct 3, and the plug screw 8 is used for blocking the second oil duct 3.
In a preferred embodiment, the bypass valve protecting structure further comprises a spring 7 disposed in the second oil passage 3, and one end of the spring 7 is in contact with the steel ball 4; the bracket 6 is cast.
In practical application, a first oil duct 2 and a second oil duct 3 are arranged on the bottom plate 1, and the first oil duct 2 is larger than the second oil duct 3. When the pressure of the first oil duct 2 is greater than the pressure of the second oil duct 3, the oil pushes the steel ball 4 to move backwards (to move towards the second oil duct 3), the first oil duct 2 is communicated with the second oil duct 3, the oil is decompressed through the decompression hole 5, and the pressure of the first oil duct 2 can be kept within a certain range by properly designing the spring 7 force of the spring 7. Through setting up bracket 6 in the centre of relief hole 5, can prevent that steel ball 4 from falling into relief hole 5, can effectively avoid the inefficacy of bypass valve.
In a word, the bypass valve protection structure is simple and reasonable in structure, low in cost, long in service life and high in practicability, failure of the bypass valve can be effectively avoided, the failure rate of parts can be effectively reduced, and the bypass valve protection structure is convenient to install, popularize and use.
The foregoing descriptions of specific exemplary embodiments of the present invention are presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application to thereby enable one skilled in the art to make and utilize the invention in various exemplary embodiments and with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
