Description

Technical Field

[0001] This utility model relates to the field of hydraulic power station valve block technology, specifically a hydraulic power station valve block structure. Background Technology

[0002] The valve block of the hydraulic power unit is an important component of the hydraulic power unit. It is a key component in the hydraulic system used to install, connect and control hydraulic valves. The letters marked on it represent different oil ports and functions. The flow direction, pressure and flow rate of hydraulic oil are regulated through these oil ports.

[0003] In traditional hydraulic power station valve block structures, when hydraulic oil flows inside the valve block, due to the working characteristics of the hydraulic system, the hydraulic oil generates a lot of heat during the flow process. Especially in the oil inlet area, the flow rate and pressure of the hydraulic oil change more complexly, which can easily generate local high temperatures. If this heat cannot be dissipated in time, it will cause the valve body temperature to rise. The rise in valve body temperature will lead to the deterioration of the hydraulic oil due to excessive temperature. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic power station valve block structure that solves the problem of traditional hydraulic power station valve block structures. When hydraulic oil flows inside the valve block, due to the working characteristics of the hydraulic system, the hydraulic oil generates a lot of heat during the flow process. Especially in the oil inlet area, the flow rate and pressure of the hydraulic oil change more complexly, which easily generates local high temperature. If this heat cannot be dissipated in time, it will cause the valve body temperature to rise, which will lead to the deterioration of the hydraulic oil due to excessive temperature.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a hydraulic power station valve block structure, comprising a valve body, an oil inlet channel inside the valve body, an oil inlet pipe connector inside the valve body, the oil inlet pipe connector being connected to the inside of the oil inlet channel, a return oil pipe connector inside the valve body, a male oil storage tank connector inside the valve body, a female return oil pipe connector inside the valve body, an operating valve mounted on the upper surface of the valve body, an oil filter mounted on the lower surface of the valve body, an installation groove on one side of the valve body, the installation groove being located above the oil inlet channel, a heat dissipation mechanism mounted inside the installation groove, the heat dissipation end of the heat dissipation mechanism abutting against the inner surface of the installation groove above the oil inlet channel, and a flow slowing component mounted inside the oil inlet channel.

[0007] Furthermore, the heat dissipation mechanism includes a limiting plate, and a mounting base is fixedly installed on one side of the limiting plate, the mounting base being inserted into the interior of the mounting groove.

[0008] Furthermore, a plurality of aluminum heat dissipation fins are fixedly installed on the inner surface of the mounting base, and the aluminum heat dissipation fins abut against the inner surface of the mounting groove above the oil inlet channel.

[0009] Furthermore, the limiting plate has several connecting bolts connected to its internal threads, and all of these connecting bolts are connected to the internal threads of the valve body.

[0010] Furthermore, the limiting plate has several heat dissipation holes inside.

[0011] Furthermore, the flow-retarding component includes a limiting tube and a spiral blade. The limiting tube is fixedly installed inside the oil inlet channel, and the spiral blade is fixedly installed on the peripheral side of the limiting tube.

[0012] This utility model has the following beneficial effects:

[0013] (1) In the hydraulic system, hydraulic oil enters the inlet channel inside the valve body through the inlet pipe joint. After the hydraulic system has been running for a period of time, the hydraulic oil will generate heat during the flow process. This heat will cause the temperature of the valve body to rise, especially the area around the inlet channel. At this time, the heat dissipation mechanism begins to play its role. The heat dissipation mechanism is installed in the mounting groove on one side of the valve body, and its heat dissipation end abuts against the inner surface of the mounting groove above the inlet channel. The aluminum heat dissipation fins can quickly conduct away the heat generated near the inlet channel. Through the heat dissipation holes on the limit plate, heat exchange with the surrounding environment is achieved to dissipate heat and cool down the valve body. The temperature of the valve body can be reduced in a timely and effective manner to prevent the hydraulic oil from deteriorating due to excessive temperature and ensure the stable operation of the hydraulic system.

[0014] (2) Before the hydraulic oil in the oil inlet channel of this utility model flows to the subsequent hydraulic components, it will first pass through the slow flow component. The limiting tube and the spiral blade in the slow flow component cooperate to make the hydraulic oil flow through the path of the spiral blade, thereby extending the flow distance of the hydraulic oil, increasing the contact time between the hydraulic oil and the heat dissipation mechanism, and further improving the heat dissipation efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a hydraulic power station valve block structure, including a valve body 1, an oil inlet channel 101 inside the valve body 1, an oil inlet pipe connector 2 installed inside the valve body 1, the oil inlet pipe connector 2 and the oil inlet channel 101 are connected inside the valve body 1, a return oil pipe connector 3 is installed inside the valve body 1, a male oil storage tank connector 4 is installed inside the valve body 1, a female return oil pipe connector 5 is installed inside the valve body 1, an operating valve 6 is installed on the upper surface of the valve body 1, an oil filter 7 is installed on the lower surface of the valve body 1, an installation groove 102 is opened on one side of the valve body 1, the installation groove 102 is opened above the oil inlet channel 101, a heat dissipation mechanism 8 is installed inside the installation groove 102, the heat dissipation end of the heat dissipation mechanism 8 abuts against the inner surface of the installation groove 102 above the oil inlet channel 101, and a flow slowing component is installed inside the oil inlet channel 101.

[0025] The heat dissipation mechanism 8 includes a limiting plate 801, and a mounting base 802 is fixedly installed on one side of the limiting plate 801. The mounting base 802 is inserted into the inside of the mounting groove 102.

[0026] Several aluminum heat dissipation fins 803 are fixedly installed on the inner surface of the mounting base 802, and the aluminum heat dissipation fins 803 abut against the inner surface of the mounting groove 102 above the oil inlet passage 101.

[0027] The limiting plate 801 has several connecting bolts 804 internally threaded, and all connecting bolts 804 are connected to the internal threads of the valve body 1.

[0028] The limiting plate 801 has several heat dissipation holes 805 inside;

[0029] In the hydraulic system, hydraulic oil enters the inlet passage 101 inside the valve body 1 through the inlet pipe joint 2. After the hydraulic system has been running for a period of time, the hydraulic oil will generate heat during the flow process. This heat will cause the temperature of the valve body 1 to rise, especially in the area around the inlet passage 101. At this time, the heat dissipation mechanism 8 begins to play its role. The heat dissipation mechanism 8 is installed in the mounting groove 102 on one side of the valve body 1, and its heat dissipation end abuts against the inner surface of the mounting groove 102 above the inlet passage 101. The aluminum heat dissipation fins 803 can quickly conduct away the heat generated near the inlet passage 101. Through the heat dissipation holes 805 on the limit plate 801, heat exchange with the surrounding environment is achieved to dissipate heat and cool down the valve body 1. This can effectively reduce the temperature of the valve body 1 in a timely manner, prevent the hydraulic oil from deteriorating due to excessive temperature, and ensure the stable operation of the hydraulic system.

[0030] The flow control assembly includes a limiting tube 9 and a spiral blade 10. The limiting tube 9 is fixedly installed inside the oil inlet channel 101, and the spiral blade 10 is fixedly installed on the circumferential side of the limiting tube 9.

[0031] Before flowing to subsequent hydraulic components, the hydraulic oil in the oil inlet 101 passes through the flow-retarding component. The limiting tube 9 and the spiral blade 10 in the flow-retarding component work together to make the hydraulic oil flow through the path of the spiral blade 10, thereby extending the flow distance of the hydraulic oil, increasing the contact time between the hydraulic oil and the heat dissipation mechanism, and further improving the heat dissipation efficiency.

[0032] In operation, hydraulic oil first enters the inlet channel 101 inside the valve body 1 through the inlet pipe connector 2 in the hydraulic system. After the hydraulic system has been running for a period of time, the hydraulic oil will generate heat during the flow process. This heat will cause the temperature of the valve body 1 to rise, especially in the area around the inlet channel 101. At this time, the heat dissipation mechanism 8 begins to play its role. The heat dissipation mechanism 8 is installed in the mounting groove 102 on one side of the valve body 1, and its heat dissipation end abuts against the inner surface of the mounting groove 102 above the inlet channel 101. The aluminum heat dissipation fins 803 can quickly conduct away the heat generated near the inlet channel 101. Through the heat dissipation holes 805 on the limit plate 801, heat exchange with the surrounding environment is achieved to dissipate heat and cool down the valve body 1. This can effectively reduce the temperature of the valve body 1 in a timely manner, prevent the hydraulic oil from deteriorating due to excessive temperature, and ensure the stable operation of the hydraulic system.

[0033] Before flowing to subsequent hydraulic components, the hydraulic oil in the oil inlet 101 passes through the flow-retarding component. The limiting tube 9 and the spiral blade 10 in the flow-retarding component work together to make the hydraulic oil flow through the path of the spiral blade 10, thereby extending the flow distance of the hydraulic oil, increasing the contact time between the hydraulic oil and the heat dissipation mechanism, and further improving the heat dissipation efficiency.
