Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model aims to provide a high-pressure jet vacuum valve and a metalworking fluid circulation system to solve the problems existing in the above-mentioned prior art, improve the metalworking fluid circulation efficiency, and save energy consumption at the same time.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model provides a high-pressure jet vacuum valve 100, comprising a valve body 1 and an inlet pipe 3, the valve body 1 having a liquid inlet section 101, a communication chamber 102, an injection section 103 and a liquid outlet section 104 which are connected in sequence, the diameters of the liquid inlet section 101 and the liquid outlet section 104 are both larger than the diameter of the injection section 103; the liquid inlet section 101 is provided with a liquid inlet pipe 2, the liquid inlet pipe 2 is a variable diameter structure, one end of the liquid inlet pipe 2 extends into the communication chamber 102, and there is a gap between the end of the liquid inlet pipe 2 extending into the communication chamber 102 and the inner wall of the valve body 1, and the other end of the liquid inlet pipe 2 is connected to the valve body 1; the inner diameter of the liquid inlet pipe 2 on the side close to the liquid inlet section 101 is larger than the inner diameter of the liquid inlet pipe 2 on the side close to the liquid outlet section 104; the valve body 1 can be connected to a conveying pipeline of a metalworking fluid; one end of the inlet pipe 3 is connected to the communication chamber 102; the other end of the inlet pipe 3 can be connected to the metalworking fluid to be purified.

[0029] In the high-pressure jet vacuum valve 100 of the utility model, liquid is input from the liquid inlet section 101 and enters the liquid inlet pipe 2. As the inner diameter of the liquid inlet pipe 2 becomes smaller, the liquid is ejected from the liquid inlet pipe 2 at high speed and enters the ejection section 103, and a local vacuum is formed in the communication chamber 102, so that the liquid in the pipe 3 is sucked in under the action of negative pressure, and the mixed liquid is output from the liquid outlet section 104. The utility model adopts the Bernoulli principle, and while conveying the metalworking fluid to the purification equipment, the metalworking fluid at the tool of the processing equipment is sucked away, thereby improving the circulation efficiency of the metalworking fluid and saving energy consumption.

[0030] Among them, the liquid inlet pipe 2 is a stepped structure, and the end with a larger outer diameter of the liquid inlet pipe 2 is detachably connected to the valve body 1, which is convenient for the disassembly and assembly of the liquid inlet pipe 2, and a sealing element is arranged between the liquid inlet pipe 2 and the valve body 1 to avoid leakage. The end with a smaller outer diameter of the liquid inlet pipe 2 extends into the connecting chamber 102 to ensure that the liquid introduced by the liquid inlet pipe 2 enters the connecting chamber 102 and is ejected through the injection section 103.

[0031] It should also be noted that the end of the liquid inlet pipe 2 extending into the communication chamber 102 has a guide mechanism 201, which is a conical structure, and the outlet of the liquid inlet pipe 2 is arranged on the end surface of the guide mechanism 201 and is arranged directly opposite the injection section 103. The end of the liquid inlet pipe 2 close to the injection section 103 has a conical guide mechanism 201, which plays a role in guiding the liquid introduced into the confluence pipe 3, so that after entering the communication chamber 102, it flows smoothly toward the injection section 103, further improving the working reliability of the device.

[0032] The gap between the liquid inlet pipe 2 and the inner wall of the valve body 1 forms a confluence space 4, and the confluence pipe 3 is connected to the confluence space 4. In the present specific embodiment, the liquid inlet pipe 2 and the valve body 1 are coaxially arranged to keep the gap therebetween uniform, thereby improving the uniformity of the liquid sucked into the connecting chamber 102 and enhancing the working stability of the high-pressure jet vacuum valve 100.

[0033] In this specific embodiment, the inlet pipe 3 is detachably connected to the valve body 1, and a threaded connection method can be selected, which is convenient for disassembly and assembly, providing convenience for subsequent device maintenance.

[0034] Specifically, the liquid inlet section 101 and the liquid outlet section 104 are both connected to the injection section 103 by a transition section. The transition section is a conical structure to avoid dead angles that affect liquid flow and injection, thereby improving the mechanical properties of the liquid.

[0035] More specifically, the end of the liquid inlet pipe 2 away from the valve body 1 is connected with an inlet connecting pipe 5, and the liquid outlet section 104 is provided with an outlet connecting pipe 6, which is detachably connected to the valve body 1. The inlet connecting pipe 5 and the outlet connecting pipe 6 can both be connected to the metalworking fluid delivery pipeline, which facilitates the high-pressure jet vacuum valve 100 to be connected to the metalworking fluid circulation pipeline, and improves the convenience of its connection with the pipeline. The inlet connecting pipe 5 is detachably connected to the liquid inlet pipe 2, and the inner diameter of the inlet connecting pipe 5 is larger than the inner diameter of the liquid inlet pipe 2, which ensures the smooth input of the liquid. Moreover, the inlet connecting pipe 5 and the outlet connecting pipe 6 are both detachably connected, which further improves the flexibility and adaptability of the high-pressure jet vacuum valve 100. In practical applications, in order to facilitate the connection of the inlet connecting pipe 5 and the outlet connecting pipe 6 with other pipelines, a connection structure, such as a plug-in or clamping structure, can be provided at the end of the inlet connecting pipe 5 and the outlet connecting pipe 6 to facilitate the connection operation of the pipeline.

[0036] Furthermore, the utility model also provides a metalworking fluid circulation system, including the above-mentioned high-pressure jet vacuum valve 100. During the machining process, the above-mentioned high-pressure jet vacuum valve 100 is used to suck away the metalworking fluid to be treated, without the need to separately set up a pump body to absorb the metalworking fluid, thereby saving the working energy consumption of the metalworking fluid circulation system.

[0037] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
