Description

Technical Field

[0001] This utility model relates to the field of flushing valve technology, and in particular to a novel flushing valve. Background Technology

[0002] In travel motor systems, the opening, closing, and return processes of the built-in flushing valve significantly impact the heat dissipation stability and cleanliness of the entire hydraulic system. To achieve precise and stable oil delivery and flushing operations for the travel motor, an active circulation system using a built-in flushing valve is typically required. This valve usually includes auxiliary functional modules such as one-way throttling, low-pressure overflow, and constant-temperature cooling. Especially under continuous heavy-load conditions, with high-pressure overflow and instantaneous temperature rise, the valve's flow capacity and heat dissipation performance directly affect oil delivery stability and motor lifespan. Therefore, developing an integrated, efficient, and stable oil delivery travel motor with a built-in flushing valve has become an important direction for technological improvement.

[0003] In existing technologies, the structure used for the built-in flushing valve of a walking motor generally includes a one-way valve core, a low-pressure overflow channel, and auxiliary heat dissipation holes. Specifically, the valve body has a throttling orifice for connecting the high and low pressure chambers, which is sealed and fixed using screws or riveting. It is also equipped with a return oil filter and side wall heat dissipation grooves to dissipate heat from the high-temperature oil and prevent the valve core from jamming. In actual use, the throttling orifice diameter and overflow pressure are factory-set and not adjustable. When the oil temperature fluctuates, the throttling coefficient drifts accordingly, causing the flushing flow rate to fluctuate greatly. This results in unstable and smooth oil output during actual use, making operation cumbersome.

[0004] However, existing walking motors with built-in flushing valves still have certain problems in practical applications. On the one hand, when hydraulic oil enters, the traditional structure cannot stably and smoothly discharge the hydraulic oil, affecting the flushing efficiency and causing hydraulic oil to accumulate inside the flushing valve, resulting in valve washing. These problems reduce the efficiency of the built-in flushing valve and urgently need to be optimized in structural design. Therefore, a new type of flushing valve is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel flushing valve, which aims to improve the problem that flushing valves in the prior art cannot stably output oil during operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel flushing valve, comprising: a valve body, wherein the valve body serves as the basic structure of the entire flushing valve, and is used to integrate and fix various internal components to ensure the overall stability and sealing of the flushing valve;

[0007] The flushing valve core is slidably connected to the inside of the valve body on its outer wall. As the core control component of the flushing valve, the flushing valve core ensures precise control and efficient operation of the flushing process.

[0008] Oil inlet A is located on one side of the valve body and serves as one of the main channels for fluid to enter the valve.

[0009] The B inlet is located on the other side of the valve body and serves as another main channel for fluid to enter the valve.

[0010] The T-port is located at a specific position on the valve body and is used to discharge fluid or connect to an external circuit;

[0011] A smoothing component, disposed inside the valve body, is used to stably and smoothly discharge hydraulic oil added from either inlet A or inlet B.

[0012] As a further description of the above technical solution:

[0013] A spring seat is slidably connected inside the valve body, and a threaded plug is fixedly connected inside the valve body.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the spring seat is fitted with a left-side spring. One end of the left-side spring is fixedly connected to one end of the spring seat, and the other end of the left-side spring is fixedly connected to the end near the threaded plug.

[0016] As a further description of the above technical solution:

[0017] A spring seat is slidably connected inside the valve body, and a threaded plug is fixedly connected inside the valve body.

[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The smoothing component includes an elastic retaining ring for the orifice, the outer wall of which is fixedly connected to the inside of the valve body.

[0022] As a further description of the above technical solution:

[0023] A throttling plug is fixedly connected to the top of the orifice by an elastic retaining ring, and a pressure-holding valve core is fixedly connected to the top of the throttling plug.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, when hydraulic oil flows in from the flushing valve core, it flows into the through hole through the elastic retaining ring from the notch above the flushing valve core. Then, under the action of the pressure holding valve core, the pressure is kept constant, so that the hydraulic oil flows into the throttling plug. Under the throttling control of the throttling plug, it flows out of the T port stably and controllably, achieving a stable and smooth oil output effect. This solves the problem that the flushing valve cannot output oil stably and smoothly during operation and improves the smoothness of the flushing valve. Attached Figure Description

The threaded plug 2 provides elastic force to ensure that the flushing valve core 5 can quickly return to its original position after actuation. One end of the left spring 3 is fixedly connected to one end of the spring seat 4, and the other end of the left spring 3 is fixedly connected to the end near the threaded plug 2. A spring seat 9 is slidably connected inside the valve body 1, serving as a support structure for the right spring 10 and transmitting spring force to assist in the reset or actuation of the flushing valve core 5.
