Description
本創作涉及一種旋轉式液壓閥改良之結構，在此專指液壓系統的控制閥，特別是控制閥之閥蕊能隨時保持平衡，以旋轉方式即可輕易改變流體方向及有效控制流量的旋轉式液壓閥。 The present invention relates to a modified hydraulic valve structure, which is specifically referred to herein as a control valve of a hydraulic system, in particular, a valve core of a control valve can be balanced at any time, and the rotation direction can be easily changed in a rotating manner and the flow rate can be effectively controlled. Hydraulic valve.
惟，習知液壓系統(Hydraulic System)乃採用「巴斯卡定律(又稱巴斯卡原理Pascal’s Pinciple)」可以將力放大，根據巴斯卡原理：「對密閉容器中不會因受到壓力而產生體積變化的流體施加壓力時，此壓力可以傳至流體的其他各部位，且其壓力強度不變」，而液壓系統的方向控制閥即為油壓系統之控制機構，負責控制調節油路中之油壓、流量和導向，能夠傳遞能量，進而使作動器達到預定之動作，例如：千斤頂之升降、可以將能量轉換成機械運動的致動器(如：直線運動之液壓缸與旋轉運動之液壓馬達)、起重機或挖土機之各種動作的實現；但，傳統液壓系統的方向控制閥若為板式閥時，因閥蕊以直線滑移之方式來控制液壓油之流動方向，不但液壓油內漏量及壓力損失較高，並需要加設閥塊做為油管之轉接連結，以致於造成體積過大、笨重，成本又高之缺失；若是傳統電磁換向閥，又無法適用於大流量的大型液壓機械，因為，如果要克服大流量液流力之穩定性、液壓 卡緊力、運動磨擦阻力，以及復位彈簧之反力等問題，就必須增大電磁鐵的推力，而導致電磁鐵太大，且要減少壓力之損失，還需要加大閥蕊的直徑，實在不符合經濟效益；由以上得知，此些缺失，不但讓液壓系統使用者帶來極大的不便與困擾，也是許多相關業者無法突破的長期缺弊。 However, the conventional hydraulic system uses the Baska's Law (also known as Pascal's Pinciple) to amplify the force. According to the Baska principle: "There is no pressure on the closed container." When a pressure is applied to a fluid that produces a volume change, the pressure can be transmitted to other parts of the fluid, and the pressure strength is constant, and the directional control valve of the hydraulic system is the control mechanism of the hydraulic system, which is responsible for controlling the oil passage. The oil pressure, flow and guidance can transfer energy, and thus the actuator can reach a predetermined action, such as: lifting of the jack, an actuator that can convert energy into mechanical motion (eg, hydraulic cylinder and rotary motion of linear motion) The realization of various actions of the hydraulic motor), the crane or the excavator; however, if the directional control valve of the conventional hydraulic system is a plate type valve, the flow direction of the hydraulic oil is controlled by the linear sliding of the valve core, not only the hydraulic oil The internal leakage and pressure loss are high, and the valve block needs to be added as the transfer connection of the oil pipe, so that the volume is too large, heavy, and the cost is high. If conventional solenoid valve, they can not apply to large-scale flow of large hydraulic machinery, because, if you want to overcome the force of the high-volume flow stability, hydraulic The clamping force, the frictional resistance of the motion, and the reaction force of the return spring must increase the thrust of the electromagnet, which causes the electromagnet to be too large, and to reduce the loss of pressure, it is also necessary to increase the diameter of the valve core. It is not in line with economic benefits; from the above, these shortcomings not only cause great inconvenience and trouble to users of hydraulic systems, but also long-term defects that many related companies cannot break through.
本創作人有鑒於前述傳統液壓系統之方向控制閥所存在的諸多問題無法突破，而加以精心研究，再積極的研發、創作，經多年從事於此一行業之專業經驗與心得，於是創作出本案之創作。 In view of the above-mentioned problems of the traditional hydraulic system directional control valve, the creator has not been able to break through, and has carefully studied, and then actively researched and developed, created, and after years of professional experience and experience in this industry, he created the case. Creation.

The groove is such that the hydraulic oil entering the valve core from the oil inlet hole is filled in the annular groove of the oil inlet portion of the valve core and the U-shaped groove of the first and second working portions connected to each other, so that the pressure of the hydraulic oil It acts on the inner wall of the valve body at any time, and the upper and lower parts of the valve core are subjected to the average force of the hydraulic oil, so that the oil pressure difference between the valve core and the shaft portion is minimized, so that the valve core and the valve body are The tightness is more precise, the leakage of hydraulic oil is minimized, and the oil pressure in the stable oil passage is effectively adjusted, so that the valve core can be kept in balance at any time without offsetting, even at high pressure, manual or electric The control method can easily rotate the valve core with a small force to change the direction of the shaft portion, control the flow of the hydraulic oil, and enable the hydraulic oil to smoothly flow in a predetermined direction to control the predetermined action of the actuator.

The annular groove (230) communicates with the two pairs of inverted U-shaped grooves (211a), (211b) and (212a), (212b) (as shown in Figure 9A), and the hydraulic oil flows to the opposite side. a pair of U-shaped grooves (221a), (221b) and (222a), (222b) disposed in the second working portion (22) and communicating with the annular groove (230) of the oil inlet portion (23) (eg In the 9th C), the upper and lower parts of the valve core (20a) are subjected to the equal force of the hydraulic oil, and the oil pressure difference is extremely small, and the balance suspension state can be maintained at any time, and the valve core can be easily rotated as long as the force is small. (20a); when the valve core (20a) rotates +60 degrees (2nd angle) with respect to the valve body (10), due to the valve core (2 The oil inlet ring groove (230) of 0a) is still in communication with the oil inlet hole (P11) of the valve body (10), and at this time, the valve core (20a) of the hydraulic oil is filled with the U of the second working portion (22). The type groove corresponds to the second working outer hole (B12) of the communication valve body (10), so that the actuator (50) generates a predetermined action, and the second working outer hole (B12) is made by the actuator (50). A working outer hole (A11) is in communication, and the first working outer hole (A11) is further connected to the U-shaped groove (213) of the first working portion (21), and then the U-shaped groove (213) and the first back The oil ring groove (T25) is connected to each other, so that the first oil return groove (T25) and the U groove (213) are filled with hydraulic oil, so that the first oil ring groove (T25) is connected. The first oil return hole (T11) of the valve body (10) flows back to the oil pressure source (30); when the valve core (20a) rotates by 60 degrees (the third angle) with respect to the valve body (10), due to the valve The oil inlet ring groove (230) of the core (20a) is still with the valve body (10) The oil inlet hole (P11) is connected. At this time, the inverted U-shaped groove of the first working portion (21) of the valve core (20a) filled with the hydraulic oil corresponds to the first working outer hole of the communication valve body (10) (A11 The actuator (50) is caused to perform a predetermined action, and the first working outer hole (A11) is communicated with the second working outer hole (B12) by the actuator (50), and the second working outer hole (B12) is again Connecting the U-shaped groove (223) of the second working portion (22), and communicating with the second oil return ring groove (T26) by the U-shaped groove (223), the second oil return concave ring The groove (T26) communicates with the second oil return hole (T12) of the valve body (10), and flows back into the oil pressure source (30); thereby, it can be seen that the pressure of the hydraulic oil acts on the working state at any time. The inner wall of the valve body (10) can not only make the tightness between the valve core (20a) and the valve body (10) less than 3um, but also achieve the minimum leakage in the hydraulic oil, and is forced by the valve core (20a). The pressure difference of the oil is quite small, the valve core (20a) can maintain the state of equilibrium suspension at any time, and improve the efficiency of work; based on the above characteristics, the rotary hydraulic valve (1) of the present invention is light, small in weight, large in power, and works. Smooth, simple structure, and easy to control Many advantages, at the same time, not only do not need the valve block as a tubing transfer connection, can be used alone, can also be used as a sheathed valve or with a plate valve, can also be used as a flow valve, greatly improving the convenience and practical use. And economic benefits.
