Further, the outer edge 32 〇1 of the piston 32 and the outer edge of the water stop 321 which is coated on the outer side of the water stop 321 is larger than the outer diameter ui (four) 彳i of the turning portion 13 for the piston guide 22 to be displaced upward. The lever portion 224 that drives the upper end is also relatively displaced upward, so that the water stop gasket 321 can cover the drain port 13 at this time, and the water stop tab 321 can be covered by the other end edge 32〇1 of the piston 32. Extending outward, the water stop 321 can completely close the drain m. In addition, in the preferred embodiment of the present invention, in the preferred embodiment, the elastic member 33 is disposed at the bottom of the piston 32 at the bottom of each position of the piston 32. Between the 326 and the accommodating groove 311 of the lower cover 31, the one end 331 of the elastic member 33 is sleeved with the chamber 326, and the other end 332 is fixed with a pad body 34 and is screwed to the locking portion 314 which is screwed to the end of the lower cover 31. In the shape, the pad body 34 can be used for the lifting portion 314 to rotate the lifting distance of the elastic member 33 to adjust the pressure exerted by the elastic member. Moreover, the piston 32 is placed in the receiving groove 311 of the lower cover 31, and the water ring 325 is disposed on the periphery. Thereby, when the piston 32 is assembled with the groove 311 of the lower cover 31 of the lower cover 31, The water stop ring 325 can be used to make the adhesion between the two better. Please refer to FIG. 2, when the pressure relief valve is actually used, the pressure relief valve uses the liquid pressure to touch and reply. During the process, when the liquid flows in from the inner hole 142 of the inlet pipe 141, through the drain port ι31 of the turning portion 13 to the inner hole 152 of the outlet pipe 151, the hydraulic pressure flows to the groove 323 and the piston guide rod 22 The through hole 220 and the through hole 21 of the upper cover 21 push the pressure gauge 23 so that the pressure gauge 23 can immediately display the data. If the safety data displayed by the pressure gauge 23 is larger, the water inlet pipe 141 is used. The hydraulic pressure generated when the liquid flows is greater than the hydraulic pressure of the water outlet pipe 151, and the hydraulic pressure generated when the liquid flows is greater than the elastic force of the elastic member 33, and then the piston 32 is pushed upward and the piston guide rod 22 is displaced upward to act as the piston guide rod. When the displacement is 22, the contact portion 224 at the upper end is also opposite. Displacement, and the water stop gasket 321 closes the drain port ι31. At this time, the line pressure operation can be performed by the water inlet pipe 141. When the hydraulic pressure of the water outlet pipe 151 is not continuously pushed and is smaller than the elastic force of the elastic member 33 inside the piston 32, The piston guide rod 22 located in the drain port 131 is also displaced back to the original position, and is abutted against the water stop washer 321 of the piston 22 by the contact portion 321 to position the piston 32 in relative displacement. When the contact portion 224 does not enter the drain port 131, an unactuated state is formed, thereby repeatedly operating, and the hydraulic pressure generated by the liquid flowing pushes the water stop gasket 321 of the piston 32 to open or close P only 1 drain port 131 〇 The structural characteristics of the above-mentioned pressure relief valve are mainly characterized by: When applied to various liquid pipelines, the hydraulic fluid can be used to drive the displacement of the piston 32, and the contact portion thereof 224 also changes the relative displacement 'the other pressure relief valve is composed of the main body 10, the push group 20 and the pressure control device 30, and the like, the purpose of starting or closing the pressure relief valve can be achieved, and the overall structural composition is quite simple. Therefore, the manufacturing cost can be greatly reduced, and it is suitable for the industrial use of the ancestral customs.
