[0002] Valves are control components in pipeline fluid delivery systems. They are used to change the cross-section of the passage and the direction of medium flow. They have functions such as diversion, cut-off, throttling, check, diversion or overflow pressure relief. The control of valves can adopt a variety of transmission methods, such as manual, electric, hydraulic, etc. In new valves, explosion-proof components can be used to divert liquids when the new valves are subjected to excessive internal pressure to avoid bursting of the valve body and pipeline.

[0003] For example, the utility model with application number CN202123109460.2 discloses a high-pressure resistant and explosion-proof valve assembly. The utility model adopts a stainless steel rod and a plastic thread to achieve fluid flow stopping, so that the valve assembly can withstand a large pressure, and a simple explosion-proof valve is used to prevent the valve assembly from being damaged due to excessive pressure. However, in the actual use of this type of explosion-proof assembly, since the elastic force of the compression spring is selected according to the pressure at which the valve is damaged, when the pressure resistance of the pipeline is lower than that of the valve, the pipeline may burst first, resulting in certain limitations when using this type of new valve.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an explosion-proof component and a new valve are provided. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The explosion-proof component and the novel valve proposed by the utility model can, through the setting of the adjustment component, utilize the rubber ring to improve the sealing performance between the sealing plate and the retaining ring when the spring seat pushes the sealing plate, thereby avoiding leakage of the explosion-proof component during normal use, and can also rotate the screw rod according to the use requirements. At this time, the guide groove and the guide block will limit the rotation of the screw sleeve on the connecting seat so that the position of the connecting seat can be adjusted, and the elastic force of the spring seat can be controlled according to the requirements to adapt to different explosion-proof requirements, which is beneficial to expanding the use range of the valve.

After the adjustment, it is only necessary to pull the gear sleeve out of the gear column, then turn it over to adjust the position, align the positioning column with the positioning sleeve, and then insert it into the gear column. At this time, the positioning sleeve will limit the positioning column to prevent the toggle block from rotating. Therefore, after the adjustment, the angle of the gear sleeve can be quickly locked to prevent the toggle block from being accidentally touched when operating the valve body, resulting in a change in the elastic force of the spring seat, which is beneficial to enhancing the stability after adjustment. At the same time, the magnet can also be used to absorb the iron positioning sleeve to prevent it from accidentally falling off. BRIEF DESCRIPTION OF THE DRAWINGS
