Description

Technical Field

[0001] The utility model relates to an energy release valve, belonging to the field of valves. Background Art

[0002] An energy release valve (also known as a "relief valve" or "safety valve") is a common control component in hydraulic and pneumatic systems, primarily used to regulate and limit fluid pressure within the system to protect the safe operation of the system and equipment. The energy release valve can be set to a maximum pressure. When the system pressure exceeds this value, the valve automatically opens, releasing excess fluid and preventing damage to the system caused by overpressure. In many industrial equipment and hydraulic systems, energy release valves serve as safety devices, rapidly discharging fluid in the event of a system failure or overpressure, thus preventing accidents. They maintain a certain pressure range within the system, regulating fluid flow according to demand, and helping to optimize system performance and efficiency. They are widely used in hydraulic systems, pneumatic control systems, the automotive industry, construction machinery, pharmaceutical equipment, chemical equipment, and various other types of mechanical equipment to ensure safe and reliable operation. Energy release valves are generally simple in structure and easy to operate, typically consisting of a valve body, spring, and valve plate.

[0003] Since the existing energy release valve cannot be fully open, impurities are easily deposited in the flow channel, affecting the sealing and reliability of the valve, and causing rust on the valve stem, further making the valve difficult to open and close, resulting in poor practical effect and service life. Utility Model Content

[0004] The purpose of the utility model is to provide an energy release valve in order to overcome the shortcomings and deficiencies of the prior art.

[0005] A kind of energy release valve includes a valve body, a valve seat, a valve cover, a rocker, a valve disc and a medium flow channel. The valve disc controls the opening and closing of the medium flow channel by rotating the rocker under the drive of the medium. A accommodating chamber for accommodating the rotation of the valve disc is provided between the valve body and the valve cover. A limit block is provided on the inner wall of the accommodating chamber for abutting the end face of the rocker to form a limit connection when the medium flow channel is opened. The limit block makes the medium flow channel fully open. Through the linkage design of the valve disc and the rocker, the opening and closing of the medium flow channel can be accurately controlled, and efficient medium flow control can be achieved to ensure the normal operation of the system. The limit block abuts the end face of the rocker to form a stable limit connection, ensuring that the valve disc can be firmly fixed in the fully open state when the medium flow channel is opened, ensuring that the valve disc can be cleaned when it is swung open, and the sealing design of the limit block and the valve disc effectively prevents the backflow of the medium and ensures the full-open state cleaning effect of the valve.

[0006] Preferably, the rocker and valve disc are connected by bolts, with the rocker extending to the end of the valve disc to form a stop surface that abuts against the stop block. This bolted connection creates a secure connection between the rocker and valve disc, reducing loosening caused by vibration or media impact, ensuring reliability during long-term use. The stop surface effectively limits the rotation range of the valve disc, allowing the valve to quickly reach a fully open or fully closed state, reducing resistance and eddy currents during fluid passage, and ensuring effective pipe cleaning.

[0007] Preferably, a pin is provided between the rocker arm and the valve disc, and a connecting channel is provided on the valve body. One end of the pin extends through the connecting channel to the outside and connects to a connecting rod synchronized with the valve disc. The connecting rod is provided with an energy releaser. Connecting the rocker arm and the valve disc via the pin ensures highly coordinated movement between the two, allowing for precise synchronization of the opening and closing of the valve disc. The energy releaser is connected to the valve disc via a shaft. When the residual medium force pushes on the valve disc, the valve disc drives the energy releaser to rise and fall, thereby mitigating the water hammer phenomenon caused by rapid valve closure.

[0008] Furthermore, the pin shaft outer sleeve is provided with a shaft sleeve located in the connecting channel. The additional shaft sleeve can avoid the increase of friction caused by corrosion.

[0009] Furthermore, the energy releaser contains hydraulic oil and is provided with an external oil storage tank, which is provided with a refueling port. The oil storage tank can visually check whether the hydraulic oil in the energy releaser is sufficient and is convenient for adding hydraulic oil.

[0010] Furthermore, a weight handle is connected to the connecting rod, and a weight is fixed to the weight handle. The weight handle provides additional deadweight to the valve disc, which helps the valve disc to quickly close when closing, ensuring that the valve can respond quickly and effectively prevent the backflow of the medium. Through the action of the weight, the valve disc can more quickly overcome the reaction force of the fluid when closing, thereby reducing the hysteresis that may occur during the valve closing process and improving the sensitivity and response speed of the valve.

[0011] Furthermore, a needle valve is installed on the connecting rod to control the opening and closing rate of the valve disc. This allows the operator to flexibly adjust the opening and closing rate of the valve disc. By adjusting the opening and closing rate of the valve disc, the impact and vibration of the fluid during flow can be effectively reduced, protecting the integrity of the pipeline and valve.

[0012] The beneficial effects of the present invention are as follows: the limit block abuts against the end face of the rocker to form a stable limit connection, ensuring that the valve disc can be firmly fixed in the full-open state when the medium flow channel is opened, ensuring that the valve disc can be cleaned when it is swung open, and combined with the sealing design of the limit block and the valve disc, it effectively prevents the backflow of the medium and ensures the full-open state cleaning effect of the valve.

[0019] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0020] like Figure 1-2The figure shows an embodiment of an energy release valve of the present invention, comprising a valve body, a valve seat, a valve cover, a rocker, a valve disc and a medium flow channel. The valve disc controls the opening and closing of the medium flow channel by rotating the rocker under the drive of the medium. A housing chamber for accommodating the rotation of the valve disc is provided between the valve body and the valve cover. A limit block is provided on the inner wall of the housing chamber for abutting against the end face of the rocker to form a limit connection when the medium flow channel is open. The limit block enables the medium flow channel to be in a fully open state. Through the linkage design of the valve disc and the rocker, the opening and closing of the medium flow channel can be precisely controlled, achieving efficient medium flow control and ensuring the normal operation of the system. The limit block abuts against the end face of the rocker to form a stable limit connection, ensuring that the valve disc can be firmly fixed in the fully open state when the medium flow channel is open, ensuring that the valve disc can be cleaned when it is swung open. Combined with the sealing design of the limit block and the valve disc, the backflow of the medium is effectively prevented, ensuring the full-open state cleaning effect of the valve.

[0021] The rocker and valve disc are connected by bolts. The rocker extends to the end of the valve disc to form a stopper surface that abuts the stop block. This bolted connection creates a secure connection between the rocker and the valve disc, reducing loosening caused by vibration or media impact, ensuring reliability during long-term use. The stopper surface effectively limits the rotation range of the valve disc, allowing the valve to quickly reach a fully open or fully closed state, reducing resistance and eddy currents during fluid passage, and ensuring effective pipe cleaning.

[0022] A pin is located between the rocker and the valve disc. The valve body is provided with a connecting channel. One end of the pin extends through the connecting channel to the outside, where it connects to a connecting rod synchronized with the valve disc. This connecting rod is equipped with an energy releaser. Connecting the rocker and the valve disc via the pin ensures highly coordinated movement between them, allowing for precise synchronization of the valve disc's opening and closing. The energy releaser is connected to the valve disc via a shaft. When residual medium force pushes on the valve disc, the disc drives the energy releaser upward and downward, mitigating the water hammer phenomenon that can occur when the valve closes rapidly.

[0023] The pin shaft outer sleeve is provided with a shaft sleeve located in the connecting channel. The additional shaft sleeve can avoid the increase of friction caused by rust.

[0024] The energy releaser contains hydraulic oil and is provided with an external oil storage tank, which is provided with a refueling port. The oil storage tank can visually check whether the hydraulic oil in the energy releaser is sufficient and is convenient for adding hydraulic oil.

[0025] The connecting rod is connected to a weight handle, to which a weight is fixed. The weight handle provides additional deadweight to the valve disc, which helps the disc close quickly when closing, ensuring a quick valve response and effectively preventing backflow of the medium. The weight helps the disc overcome the reaction force of the fluid more quickly when closing, thereby reducing the hysteresis that may occur during the valve closing process and improving the valve's sensitivity and response speed.

[0026] The connecting rod is also equipped with a needle valve, which controls the opening and closing rate of the valve disc. This allows the operator to flexibly adjust the opening and closing rate of the valve disc. By adjusting the opening and closing rate of the valve disc, the impact and vibration of the fluid during flow can be effectively reduced, protecting the integrity of the pipeline and valve. The valve body 1, valve seat 2, valve cover 21, rocker 22, valve disc 3, and medium flow channel 4 are comprised of a valve body 1, valve seat 2, valve cover 21, rocker 22, valve disc 3, and medium flow channel 4. Driven by the medium, the valve disc 3 rotates via the rocker 22 to control the flow channel 4. A chamber 11 is provided between the valve body 1 and valve cover 21 to accommodate the rotation of the valve disc 3. A stopper 12 is provided on the inner wall of the chamber 11, which abuts the end face of the rocker 22 to form a limiting connection when the medium flow channel 4 is open. This stopper 12 maintains the medium flow channel 4 in a fully open state. The coordinated design of the valve disc 3 and rocker 22 allows for precise control of the opening and closing of the medium flow channel 4, achieving efficient medium flow control and ensuring the normal operation of the system. The limit block 12 abuts against the end face of the rocker 22 to form a stable limit connection, ensuring that the valve disc 3 can be firmly fixed in the full-open state when the medium flow channel 4 is opened, and ensuring that the valve disc 3 can be cleaned when it is swung. Combined with the sealing design of the limit block 12 and the valve disc 3, the backflow of the medium is effectively prevented, ensuring the full-open state cleaning effect of the valve.

[0027] The rocker 22 and the valve disc 3 are connected by bolts. The rocker 22 extends to the end of the valve disc 3 to form a limit surface 23 that abuts the limit block 12. The bolt connection creates a secure connection between the rocker 22 and the valve disc 3, reducing loosening caused by vibration or media impact, ensuring reliability during long-term use. The limit surface 23 effectively limits the rotation range of the valve disc 3, allowing the valve to quickly reach a fully open or fully closed state, reducing resistance and eddy currents during fluid passage, and ensuring effective pipe cleaning.

[0028] A pin 24 is provided between the rocker 22 and the valve disc 3. A connecting passage 13 is provided on the valve body 1. One end of the pin 24 extends through the connecting passage 13 to connect to a connecting rod 31 synchronized with the valve disc 3. This connecting rod 31 is equipped with an energy releaser 32. Connecting the rocker 22 and the valve disc 3 via the pin 24 ensures highly coordinated movement between them, allowing for precise synchronization of the opening and closing of the valve disc 3. The energy releaser 32 is connected to the valve disc 3 via a shaft. When the residual medium force pushes on the valve disc 3, the valve disc 3 drives the energy releaser 32 upward and downward, thereby mitigating the rapid closure of the valve and the resulting water hammer.

[0029] The pin 24 is provided with a shaft sleeve 25 located in the connecting channel 13. The additional shaft sleeve 25 can avoid the increase of friction caused by rust.

[0030] The energy releaser 32 contains hydraulic oil, and the energy releaser 32 is provided with an external oil storage tank, and the oil storage tank is provided with a refueling port. The oil storage tank can visually see whether the hydraulic oil in the energy releaser 32 is sufficient, and is convenient for adding hydraulic oil.

[0031] A weight handle 33 is connected to the connecting rod 31, and a weight 34 is fixed to the weight handle 33. The weight 34 provides additional deadweight to the valve disc 3 through the arrangement of the weight handle 33, which helps the valve disc 3 to be quickly pressed together when closing, ensuring that the valve can respond quickly and effectively prevent the backflow of the medium. Through the action of the weight 34, the valve disc 3 can more quickly overcome the reaction force of the fluid when closing, thereby reducing the hysteresis that may occur during the valve closing process and improving the sensitivity and response speed of the valve.

[0032] The connecting rod 31 is also provided with a needle valve 35, which controls the opening and closing rate of the valve flap 3. This configuration allows the operator to flexibly adjust the opening and closing rate of the valve flap 3. By adjusting the opening and closing rate of the valve flap 3, the impact and vibration of the fluid during flow can be effectively reduced, protecting the integrity of the pipeline and valve.
