Description

Technical Field

[0001] The invention relates to the technical field of reversing valves, and in particular to a reversing valve for a lubrication system with a quantitative oil injection function. Background Art

[0002] The reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It is a valve that realizes the communication, cutting and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control. It can be divided into manual reversing valve, electro-hydraulic reversing valve, etc. It is also called Chris valve, which has a multi-directional adjustable channel and can change the flow direction of the fluid in time. When working, the drive transmission mechanism outside the valve rotates the drive shaft, drives the crank arm, and starts the valve plate, so that the working fluid sometimes flows from the left inlet to the lower outlet of the valve, and sometimes changes from the right inlet to the lower outlet, achieving the purpose of periodic flow change. This type of conversion valve is widely used in petroleum and chemical production, and is most commonly used in synthetic ammonia gasification systems. However, the connection position of the reversing valve is prone to leakage during the oil inlet process during use, which reduces the overall sealing effect of the reversing valve, and it is not easy to control the speed of the oil flow inside the reversing valve, which is easy to affect the overall service life of the reversing valve.

[0003] In summary, during the use of the reversing valve, the connection position is prone to leakage during the oil intake process, which reduces the overall sealing effect of the reversing valve and makes it difficult to control the flow speed of the oil inside the reversing valve, which can easily affect the overall service life of the reversing valve.

The reinforcing arc plates 84 are tightly fitted with the rotating plate 82, so that the reinforcing arc plates 84 can reinforce the bottom of the rotating plate 82, thereby increasing the bearing capacity of the rotating plate 82 itself, avoiding the situation where the rotating plate 82 falls off the connecting position due to increased wear during rotation, so as to achieve better sealing effect inside the reversing valve. The bottom of the rotating plate 82 is fixedly connected with a sealing disk 81, and the bottom of the inner surface of the sealing disk 81 is fixedly connected with a rotating guide frame 83. The middle position of the bottom of the guide frame 83 passes through the sealing disk 81 and extends to the outside of the sealing disk 81. The bottom of the rotating guide frame 83 is fixedly connected to the driving body 85. The rotating guide frame 83 rotates driven by the driving body 85, so that the rotating guide frame 83 drives the sealing disk 81 to rotate, and the sealing angle of the component is adjusted, thereby improving the stability of the internal adjustment of the reversing valve, preventing excessive shaking during the sealing process from affecting the use of the reversing valve, and at the same time avoiding the reversing valve from being subjected to the impact of the sealing of internal components for a long time, causing surface fractures, thereby further improving the overall service life of the reversing valve.

The support sleeve 95 is in contact with the sealing block 94, so that the support sleeve 95 has a movable space with the separator 91 under the support of the sealing block 94, thereby reducing the impact of the support sleeve 95 on the flow diversion of the separator 91 caused by the contact between the support sleeve 95 and the component, and the support sleeve 95 can position the rotating component, thereby avoiding the component from tilting or getting stuck due to uneven force during rotation, thereby improving the working effect of the rotating component, and the support sleeve 95 The middle position of the bottom of 5 penetrates the sealing block 94. The bottom of the inner cavity of the partition seat 91 is located on both sides of the sealing block 94 and is fixedly connected with a mounting box 92. The middle of the inner wall of both sides of the mounting box 92 is fixedly connected with a fixing frame 93. The mounting box 92 can be supported by the fixing frame 93, thereby increasing the stability of the mounting box 92 on the partition seat 91. The mounting boxes 92 are evenly distributed on the partition seat 91 to collect the residual oil, and the multi-layer space of the partition seat 91 is used to increase the internal separation effect, further avoiding the problem of oil leakage inside the reversing valve, and ensuring that the partition seat 91 can seal the oil outflow position of the reversing valve.

[0030] When in use, the oil stored inside the drainage tube 441 increases and enters the interior of the barrier sleeve 74 through the guide frame 75, and the quantitative circulation component 73 is used to adjust the circulation speed inside the collecting box 72, and the driving body 85 drives the rotating guide frame 83 to rotate, and the rotating guide frame 83 drives the blocking disk 81 to rotate, and the blocking disk 81 drives the rotating disk 453 to rotate through the rotating plate 82, and the supporting sleeve 95 supports the rotating rod 472, and the oil falling from the separation box 474 enters the interior of the separation seat 91, so that the installation box 92 is in contact with the medicine under the reinforcement of the fixed frame 93, and the interior of the containing tube 471 is protected.
