Description

Technical Field

[0001] The utility model relates to a compensating valve, in particular to a simple compensating valve suitable for mineral oil. Background Art

[0002] Existing drive devices, such as motors, require oil for lubrication and cooling to meet their long-term operational needs. Furthermore, to ensure adequate lubrication of all motor components under varying operating conditions, different oil supply lines must be selected, with coordinated compensation between these lines to maintain appropriate oil pressure and avoid turbulence and insufficient lubrication.

[0003] At present, conventional solenoid valves are mainly used to coordinate and compensate the oil directly in different pipelines through the flaps inside the controller. Its structure is complex and the implementation cost is high.

[0004] Furthermore, during actual application, it was discovered that for normal oil pipeline distribution, as long as the main line can achieve a complete oil circulation and the branch line can provide real-time replenishment, it is sufficient. Even if the main line experiences an abnormal pressure increase, the branch line can still provide relief. To this end, it is possible to consider introducing a relief valve into the lubrication line of the main motor equipment.

[0005] However, current compensation valves are often set with absolute opening and closing values, which cannot achieve real-time mutual compensation between various pipelines. They are prone to transitional switching between being open for a period of time and closed for a period of time. There is no regular pattern during the switching period, and it is only related to the oil pressure compensation of the current main pipeline, which affects the stability of the oil pressure in each pipeline.

[0006] In view of the above-mentioned defects, the designer has actively carried out research and innovation in order to create a simple compensation valve suitable for mineral oil, making it more valuable for industrial use. Utility Model Content

[0036] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] like Figure 1A simple compensation valve suitable for mineral oil includes a valve body 1. Its unique feature is that a valve head assembly 2 is installed at the front end of the valve body 1 to achieve compensation guidance of the mineral oil. At the same time, in order to be able to control the compensation guidance under different oil pressure conditions, a compensation control chamber 3 is provided in the valve body 1, and an elastic component 4 is provided in the compensation control chamber 3. In addition, in order to meet the normal compensation conduction of low oil pressure and the auxiliary overflow switching of high oil pressure, a valve core assembly 5 is sleeved on the elastic component 4, and the front end of the valve core assembly 5 is connected to the valve head assembly 2. A compensation ball 8 is movably placed in the valve head assembly 2, and the compensation ball 8 is in contact with the valve core assembly 5. Furthermore, in order to avoid turbulence during compensation and achieve directional guidance of the mineral oil, an inlet hole 6 is opened at the front end of the valve head assembly 2, and a plurality of compensation holes 7 are opened at the side end of the valve head assembly 2.

[0038] In view of a preferred embodiment of the present invention, a bearing boss 9 extends from the outside of the valve body 1, and a coupling gasket 10 is sleeved on the bearing boss 9. In this way, it can be installed on a fixed base preset on the outside of the compensation pipe to achieve external positioning of the valve body 1. At the same time, positioning grooves are distributed around the outside of the valve body 1, and a sealing gasket 11 is nested in the positioning groove. As a result, after connecting to the oil branch to be compensated, liquid-tight contact of the coupling surface is achieved. In addition, gaskets 12 can be sleeved on the front and rear ends of the sealing gasket 11. In this way, when a large coupling tolerance occurs, the gasket 12 can be used to achieve early matching and filling.

[0039] Further, the valve core assembly 5 includes a valve core body, which is sheathed with a guide block 13. The guide block 13 contacts the inner wall of the valve body 1. One end of the elastic component 4 abuts the guide block 13, and one end of the valve core body is inserted into the elastic component 4. This allows the elastic properties of the elastic component 4 to adjust the position of the valve core assembly 5 relative to the current mineral oil flow, achieving effective compensation and release. Specifically, a contact outer ring extends from the front end of the valve core assembly 5, which contacts the inner wall of the valve head assembly 2. The contact outer ring is provided with a receiving groove, in which a contact gasket 14 is embedded. This achieves an appropriate liquid-tight effect while meeting the controllable stroke of the valve core assembly 5, preventing mineral oil from flowing into the compensation control chamber 3.

[0040] In combination with actual implementation, a contact base 15 is distributed in the compensation control cavity 3, and the elastic component 4 is a spring, one end of which is sleeved on the contact base 15. In this way, there will be no improper vibration of the bottom end of the spring during compensation expansion and contraction.

[0041] To accommodate the flow compensation requirements of different compensation lines, a stop ring 16 is installed at the front end of the valve body 1, and the valve head assembly 2 is connected to the stop ring 16. This facilitates replacement of the valve head assembly 2. During use, the valve head assembly 2 and the stop ring 16 can be threaded together for enhanced convenience. Of course, if mass production is used and the need for subsequent replacement of the valve head assembly 2 is not a consideration, the two can also be welded together.

[0042] Furthermore, the valve head assembly 2 is provided with a tapered guide groove, and the compensating ball 8 contacts the tapered guide groove. In this way, the mineral oil flows from the inlet hole 6 to the compensating hole 7 at a certain flow rate under the guidance of the tapered guide groove and the compensating ball 8.

[0043] Of course, in order to facilitate users to quickly identify the compensation flow corresponding to the current compensation valve, a label 17 can be attached to the outside of the valve body 1. During implementation, the corresponding data is marked on the label 17, or a specific color is used to distinguish and refer to it, so that users can know it easily.

[0044] The working principle of this utility model is as follows:

[0045] After installation, the inlet hole 6 is connected to the main mineral oil delivery branch in the pipeline, and the compensation hole 7 is connected to the supplementary branch.

[0046] During normal use, with the elastic component 4 engaged, the compensating ball 8 slightly blocks the inlet hole 6 and the compensating hole 7, allowing them to flow through at an appropriate rate. This allows mineral oil from the main delivery branch to flow into the supplementary branch. However, this is only used for compensation, achieving flow guidance of mineral oil at different flow rates.

[0047] When the oil pressure in the main delivery branch increases, affecting the normal delivery of mineral oil therein, the oil pressure is transmitted to the valve core component 5 through the compensation ball 8, and then to the elastic component 4, causing it to undergo a certain degree of compression deformation.

[0048] At this time, the compensation ball 8 moves inward without blocking the inlet hole 6 and the compensation hole 7, thereby achieving overflow and compensation under high oil pressure.

[0049] After the oil pressure returns to normal, the elastic component 4 is reset and the compensation ball 8 also returns to its original position.

[0050] That is to say, under different oil pressure impacts of mineral oil, the compensation ball 8 can move back and forth appropriately to meet the overflow and compensation control under different flow rates, and meet the needs of daily compensation and overflow pressure equalization of the main mineral oil delivery branch and supplementary branch.

[0051] It can be seen from the above text description and the accompanying drawings that the present invention has the following advantages:

[0052] 1. It is equipped with an independent elastic component, which can provide constant elastic holding force for different oil pressures, and can realize the switching needs of daily compensation and overflow reset. It does not require an additional solenoid valve and the overall structure is relatively compact.

[0053] 2. Equipped with a valve core assembly, it can achieve effective oil pressure transmission and proper sealing to prevent mineral oil from contaminating the elastic components.

[0054] 3. A compensator is provided to control the degree of flow between the inlet and compensation holes, meeting the flow diversion needs during daily compensation. It can also achieve overflow guidance under high pressure conditions and adjust the actual conduction aperture of the inlet and compensation holes. This eliminates the need for a separate vane mechanism or a separate on-off valve, greatly simplifying the entire valve structure.

[0055] 4. A conical guide groove is provided inside the valve head assembly to facilitate better rolling of the compensation ball and achieve more accurate compensation.

[0056] 5. The overall structure is simple and easy to assemble. It can be directly connected to the oil supply pipeline to achieve the overflow connection between the main delivery branch and the supplementary branch.

[0057] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated in a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
