Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic press safety valve components, in particular to a hydraulic press safety valve component with a quick pressure relief device. Background Art

[0002] The hydraulic press safety valve assembly is a key part of the hydraulic press safety protection system. It is used to control the pressure in the hydraulic system and ensure that the system pressure is within a safe range. The hydraulic press safety valve assembly with a quick pressure relief device is based on the traditional safety valve assembly and adds a device that can quickly reduce the system pressure. It is mainly composed of basic components such as the valve body, valve core, and spring to form the main body of the safety valve. The valve body usually has an inlet and an outlet for connecting the oil circuit of the hydraulic system.

[0003] The safety valve is inconvenient to connect to the pipeline during use, and the disassembly and installation operations are cumbersome and inconvenient to use;

[0004] The existing patent (publication number: CN216009682U) discloses a safety valve for a hydraulic mechanism, including a valve body, a top cover is provided on the inner wall of the top of the valve body, and a joint is fixedly connected to the left side of the outer diameter of the connecting pipe. In this utility model, the pipe is inserted into the joint so that the pipe and the connecting pipe are in close contact. The handle is turned to rotate the threaded rod in the through hole and move toward the center position of the joint. The rotation of the threaded rod drives the clamping ring to move, and the pipe is clamped and fixed by the two clamping rings. The friction coefficient between the pipe and the clamping ring is increased by the friction teeth. It is more convenient to connect with the pipe during use, and the connection is firm, which is worthy of vigorous promotion.

[0005] In response to the above problems, existing patents have provided solutions. However, existing hydraulic press safety valve assemblies with rapid pressure relief devices mostly rely on mechanical spring drives, which have limitations in response speed. When faced with sudden high-pressure shocks, the mechanical spring type cannot quickly generate sufficient force to open the safety valve for rapid pressure relief because the elastic deformation of the spring itself takes a certain amount of time. In addition, it is not convenient to respond quickly and accurately according to the actual pressure conditions, and the safety valve is prone to opening too early or too late, affecting subsequent normal use.

[0006] To this end, a hydraulic press safety valve assembly with a quick pressure relief device is proposed. Utility Model Content

[0031] In this embodiment, by providing a rapid lifting mechanism 2, the electric lifting rod 202 has the characteristic of rapid response. It can be quickly activated after receiving a control signal. In the event of an emergency in the hydraulic press, the electric lifting rod 202 can complete the extension movement in a short time. The electric lifting rod 202 is tightly connected to the safety valve structure 1 through the connecting block 201, ensuring effective force transmission, so that the rapid lifting mechanism 2 can quickly act on the opening process of the safety valve. By providing a pressure sensor 6 and an ultrasonic sensor 3, the guide sleeve assembly 4 provides guidance for moving parts such as the valve disc 5. The pressure sensor 6 at the bottom of the valve disc 5 is a key component for achieving precise control. It can accurately monitor the pressure changes experienced by the valve disc 5 and respond promptly based on the actual pressure conditions. It works in conjunction with the controller 7 on the left side of the safety valve structure 1 to form a control closed loop. The controller 7 determines when to activate the rapid lifting mechanism 2 and other related operations based on the signal feedback from the pressure sensor 6. In addition, the ultrasonic sensor 3 can detect in real time whether there is any leakage in the safety valve structure 1 and surrounding connections, thereby improving the overall performance and reliability of the hydraulic press.

[0032] Specifically, such as Figure 5As shown, a connecting rod 8 is bolted to the bottom of the ultrasonic sensor 3 , and a detection component 9 is bolted to the bottom of the connecting rod 8 .

[0033] Specifically, such as Figure 5 As shown, a connecting plate 10 is bolted to a side of the ultrasonic sensor 3 close to the safety valve structure 1 , and a side of the connecting plate 10 close to the safety valve structure 1 is bolted to the safety valve structure 1 .

[0035] In this embodiment: the ultrasonic sensor 3 can better detect whether there is leakage in the safety valve structure 1 and the surrounding connections through the connecting rod 8 and the detection component 9. The connecting plate 10 makes it firmly connected to the safety valve structure 1.

The spring 18 and the pre-installed hole 19 on the inner wall of the safety valve structure 1 are conducive to the normal operation of the safety valve structure 1. The spring 18 can assist the safety valve structure 1 in opening or closing. The pre-installed hole 19 facilitates the installation or structural design of related components, thereby ensuring the performance of the safety valve structure 1.

[0042] Working Principle: During use of the safety valve structure 1 and ultrasonic sensor 3, the provision of a rapid lifting mechanism 2 enables the electric lift rod 202 to respond quickly. Upon receiving a control signal, it can be activated quickly. In the event of an emergency in the hydraulic press, the electric lift rod 202 can quickly extend. The connecting block 201 tightly connects the electric lift rod 202 to the safety valve structure 1, ensuring effective force transmission and enabling the rapid lifting mechanism 2 to quickly activate the safety valve. By providing a pressure sensor 6 and ultrasonic sensor 3, the guide sleeve assembly 4 provides guidance for moving components such as the valve disc 5. The pressure sensor 6 at the bottom of the valve disc 5 is a key component for precise control. It accurately monitors pressure changes within the valve disc 5 and can respond promptly based on actual pressure conditions. Working in conjunction with the controller 7 on the left side of the safety valve structure 1, it forms a closed control loop. Based on the signal fed back by the pressure sensor 6, the controller 7 determines when to activate the rapid lifting mechanism 2 and other related operations.
