Description

Technical Field

[0001] This utility model relates to the field of hydraulic power transmission and control, and in particular to a three-channel oil distributor for a master control switch. Background Technology

[0002] In the field of hydraulic power transmission and control, the distributor plays a crucial role as a key component. With the continuous advancement of industrial technology and the increasing diversification of application scenarios, the types of distributors are also becoming more numerous. Currently, the most widely used distributors are mainly divided into two categories: single-channel distributors and single-function multi-channel distributors.

[0003] A single-channel hydraulic distributor, as the name suggests, has a relatively simple design principle, mainly controlling the flow of hydraulic oil through a single valve block passage and a directional valve. This structural simplicity gives single-channel distributors advantages in manufacturing cost and maintenance. However, its limitations are also quite obvious: it can only meet the power supply needs of a single device and cannot achieve power distribution and control between multiple devices. A single-function multi-channel hydraulic distributor improves upon the single-channel distributor by adding multiple channels to meet the power requirements of different devices or systems.

[0004] The aforementioned device has the following drawbacks: while existing oil distributors improve the flexibility and efficiency of power transmission to some extent, they are still limited by their single-function characteristics, meaning each channel can only perform a single power control task. Therefore, in application scenarios requiring complex power supply and control for multiple devices, single-function multi-channel oil distributors are also inadequate. To address this issue, a three-channel oil distributor with a master control switch is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a three-channel oil distributor with a master control switch, which aims to improve the problem of insufficient controllability in the multi-channel hydraulic oil supply of the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a three-channel oil distributor with a master control switch, comprising a main valve block assembly, a branch valve block assembly on the front surface of the main valve block assembly, an oil receiving tray assembly on the bottom surface of the main valve block assembly, the main valve block assembly including a main valve block, a hydraulically controlled check valve fixedly installed at the cartridge valve hole at the axial center of the upper surface of the main valve block, a pressure relief valve fixedly installed at the cartridge valve hole at the right end of the upper surface of the main valve block, a two-position three-way solenoid directional valve fixedly installed on the upper surface of the main valve block near the front end of the hydraulically controlled check valve, an adjustable flow valve fixedly installed at the front cartridge valve hole on the left side of the upper surface of the main valve block, a two-position two-way solenoid directional valve fixedly installed at the rear cartridge valve hole of the upper surface of the main valve block near the adjustable flow valve, and a plate filter detachably connected to the right surface of the main valve block by bolts.

[0007] As a further description of the above technical solution: the main valve block assembly also includes a high-pressure accumulator, a low-pressure accumulator, a soft-start accumulator, and a pressure gauge. The high-pressure accumulator, low-pressure accumulator, soft-start accumulator, and pressure gauge are all connected to the main valve block through connectors. The high-pressure accumulator is connected in series with the high-pressure oil circuit of the main valve block, and the low-pressure accumulator is connected in series with the return oil circuit of the main valve block. The inlet and outlet ports of the hydraulic check valve and the pressure relief valve are respectively connected in series with the high-pressure oil circuit of the main valve block.

[0008] As a further description of the above technical solution: the two-position three-way solenoid directional valve, the two-position two-way solenoid directional valve, the adjustable flow valve, the soft-start accumulator and the high-pressure oil circuit of the main valve block are connected in parallel.

[0009] As a further description of the above technical solution: the valve block assembly includes an oil distribution valve block, a high-pressure ball valve is connected to the oil outlet port of the oil distribution valve block, and a one-way valve is connected to the oil return port of the oil distribution valve block.

[0010] As a further description of the above technical solution: the internal passage of the oil separator valve block is configured as a one-to-three configuration.

[0011] As a further description of the above technical solution: the oil receiving tray assembly includes an oil receiving tray, valve block connecting brackets are welded to the left and right ends of the upper surface of the oil receiving tray, support legs are welded to the left and right ends of the lower surface of the oil receiving tray, and an oil drain port is threadedly connected to the groove at the left end of the lower surface of the oil receiving tray.

[0012] As a further description of the above technical solution: the front surface of the main valve block is detachably connected to the rear surface of the oil separator valve block.

[0013] As a further description of the above technical solution: the oil receiving tray is fixedly installed on the lower surface of the main valve block through a valve block connecting bracket.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by utilizing the mutual cooperation between the components in the main valve block assembly and the branch valve block assembly through the connection relationship, the internal passage of the oil distribution valve block is in the form of one-to-three, which divides the hydraulic oil output from the main valve block assembly into three paths, enabling the equipment to simultaneously provide hydraulic oil to multiple devices, meeting the needs of multi-device collaborative work, and improving the control effect and working efficiency of the equipment.

In this utility model, through the mutual cooperation between the components in the main valve block assembly and the oil receiving pan assembly, the high-pressure accumulator and the low-pressure accumulator are connected in series with the high-pressure oil circuit and the return oil circuit, respectively.

[0024] Reference Figures 1-2 This utility model provides an embodiment of a three-channel oil distributor for a master control switch, including a main valve block assembly 1, a branch valve block assembly 2 on the front surface of the main valve block assembly 1, and an oil receiving pan assembly 3 on the bottom surface of the main valve block assembly 1. The main valve block assembly 1 includes a main valve block 107. A hydraulic control check valve 104 is fixedly installed at the cartridge valve hole at the center of the upper surface of the main valve block 107. Its function is to control the unidirectional flow of hydraulic oil, prevent backflow of oil, and ensure the positive circulation of oil in the hydraulic system. A pressure relief valve 111 is fixedly installed at the cartridge valve hole at the right end of the upper surface of the main valve block 107. It is mainly used to release excess pressure oil when the system pressure is too high, thereby protecting the hydraulic system and preventing damage to the system due to excessive pressure. A two-position three-way solenoid directional valve 110 is fixedly installed on the upper surface of the main valve block 107 near the front end of the hydraulic control check valve 104. It switches the oil circuit on and off through electromagnetic control, realizing centralized control of the hydraulic equipment and enabling it to switch between different working states.

[0025] Reference Figures 1-2 An adjustable flow valve 106 is fixedly installed at the front cartridge valve hole on the left side of the upper surface of the main valve block 107. This valve is used to adjust the flow rate of hydraulic oil, thereby controlling the movement speed of the hydraulic equipment. A two-position two-way solenoid directional valve 105 is fixedly installed at the rear cartridge valve hole near the adjustable flow valve 106 on the upper surface of the main valve block 107. This valve is also controlled electromagnetically to open and close the oil circuit, assisting in the reversing operation of the hydraulic system. A plate filter 109 is detachably connected to the right surface of the main valve block 107 via bolts. This filter is used to filter impurities in the hydraulic oil, ensuring... To ensure the cleanliness of the hydraulic oil and extend the service life of the hydraulic system, the main valve block assembly 1 also includes a high-pressure accumulator 108, a low-pressure accumulator 101, a soft-start accumulator 102, and a pressure gauge 103. The high-pressure accumulator 108, the low-pressure accumulator 101, the soft-start accumulator 102, and the pressure gauge 103 are all connected to the main valve block 107 through connectors. The high-pressure accumulator 108 is connected in series with the high-pressure oil circuit of the main valve block 107. Its function is to absorb the pulsation generated by the hydraulic power source, stabilize the pressure of the high-pressure oil circuit, and reduce the impact of pressure fluctuations on the system.

[0026] Reference Figures 1-2The low-pressure accumulator 101 is connected in series with the return oil circuit of the main valve block 107 to absorb the pulses generated by the equipment and prevent pressure shocks in the return oil circuit from damaging the system. The inlet and outlet ports of the hydraulic control check valve 104 and the pressure relief valve 111 are connected in series with the high-pressure oil circuit of the main valve block 107 to control the pressure value and switching of the high-pressure oil circuit, ensuring that the system operates under safe pressure. The two-position three-way solenoid directional valve 110, the two-position two-way solenoid directional valve 105, the adjustable flow valve 106, the soft-start accumulator 102, and the high-pressure oil circuit of the main valve block 107 are also connected. The system is connected in parallel. The two-position three-way solenoid directional valve 110 controls the on / off state of the hydraulic control check valve 104 to achieve precise control of the unidirectional flow of hydraulic oil. The soft-start accumulator 102 slowly increases the pressure in the high-pressure pipeline to avoid shock caused by a sudden pressure increase during system startup. The two-position two-way solenoid directional valve 105 and the adjustable flow valve 106 are used for high and low pressure switching of the oil distributor to adjust the pressure level of the hydraulic system according to different working requirements. The pressure gauge 103 monitors the outlet pressure in real time, allowing operators to understand the system pressure status in a timely manner and ensuring the normal operation of the equipment.

[0027] Reference Figure 1 and Figure 3 The valve block assembly 2 includes a distributor valve block 201. The front surface of the main valve block 107 is detachably connected to the rear surface of the distributor valve block 201. A high-pressure ball valve 202 is connected to the oil outlet port of the distributor valve block 201, which is used to manually control the output of hydraulic oil and achieve precise control of on / off. A check valve 203 is connected to the oil return port of the distributor valve block 201 to prevent hydraulic oil in the return oil circuit from flowing to the equipment end, ensuring the normal working state of the equipment and avoiding the adverse effects of oil backflow on the equipment. The internal passage of the distributor valve block 201 is set to a one-to-three configuration, which divides the hydraulic oil output from the main valve block assembly 1 into three paths to supply multiple devices and meet the hydraulic oil needs of multiple devices at the same time.

[0028] Reference Figure 1 and Figure 4 The oil receiving pan assembly 3 includes an oil receiving pan 302, which is fixedly installed on the lower surface of the main valve block 107 via a valve block connecting bracket 301. The valve block connecting bracket 301 is welded to the left and right ends of the upper surface of the oil receiving pan 302 for connection and fixation with the main valve block assembly 1, ensuring the stability of the entire oil distributor structure. The left and right ends of the lower surface of the oil receiving pan 302 are welded with support legs 304 for supporting the entire oil distributor and keeping the equipment in a stable working state. An oil drain port 303 is threaded into the groove at the left end of the lower surface of the oil receiving pan 302 for draining the hydraulic oil stored inside the oil receiving pan, facilitating equipment maintenance and upkeep.

[0029] Working principle:

[0030] Pressure control and stabilization: The high-pressure accumulator 108 is connected in series in the high-pressure oil circuit of the main valve block 107. It is responsible for absorbing the pulsation generated by the hydraulic power source, thereby stabilizing the pressure of the high-pressure oil circuit and avoiding the adverse effects of pressure fluctuations on the system. The pressure relief valve 111 can release excess pressure oil when the system pressure is too high, so as to protect the hydraulic system and prevent damage due to excessive pressure.

[0031] The two-position three-way solenoid directional valve 110 switches the oil circuit on and off via electromagnetic control, realizing centralized control of different working states of hydraulic equipment. The two-position two-way solenoid directional valve 105 also uses electromagnetic control to realize the oil circuit on and off. The two work together to complete the switching operation of the hydraulic system. The adjustable flow valve 106 is used to adjust the flow rate of hydraulic oil, thereby controlling the movement speed of hydraulic equipment. The hydraulic control check valve 104 controls the unidirectional flow of hydraulic oil, prevents backflow of oil, and ensures the positive circulation of oil in the hydraulic system. The pressure gauge 103 monitors the outlet pressure in real time, which makes it convenient for operators to understand the system pressure status and ensure the normal operation of the equipment. The soft start accumulator 102 is connected in parallel with the high-pressure oil circuit, so that the high-pressure pipeline is slowly pressurized, avoiding the impact caused by the sudden pressure rise when the system starts.

[0032] The internal passage of the oil distributor 201 is a one-to-three type, which divides the hydraulic oil output from the main valve block assembly 1 into three paths to supply multiple devices and meet the hydraulic oil needs of multiple devices at the same time. The high-pressure ball valve 202 is connected to the oil outlet port of the oil distributor 201 for manual control of the hydraulic oil output, so as to achieve precise operation control of the equipment. The one-way valve 203 is connected to the oil return port of the oil distributor 201 to prevent the hydraulic oil in the oil return path from flowing to the equipment end, ensuring the normal operation of the equipment and avoiding the adverse effects of oil backflow on the equipment.

[0033] The oil receiving tray 302 is fixedly installed on the lower surface of the main valve block 107 via the valve block connecting bracket 301. The valve block connecting brackets 301 at both ends of its upper surface are used to connect and fix it to the main valve block assembly 1 to ensure the stability of the entire oil distributor structure. The support legs 304 at both ends of the lower surface of the oil receiving tray 302 are used to support the entire oil distributor and keep the equipment in a stable working state. The oil drain port 303 is threaded into the groove at the left end of the lower surface of the oil receiving tray 302 to drain the hydraulic oil stored inside the oil receiving tray, which facilitates the maintenance and upkeep of the equipment.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
