Description

Technical Field

[0001] This utility model belongs to the field of overflow valve technology, and specifically relates to an overflow valve with an overpressure alarm function. Background Technology

[0002] An overflow valve is a device in a hydraulic system that limits the maximum system pressure. Through the action of the valve core and spring, it controls the pressure of the fluid flow in the hydraulic system to prevent machine damage or hose rupture. The set pressure of the overflow valve must be slightly higher than the actual requirement to maintain stable system operation.

[0003] Current relief valves do not provide alarm functions. When the pressure of liquid flowing through the relief valve is too high, an alarm cannot be triggered in time to notify the workers. Overpressure can easily damage the relief valve or even paralyze the hydraulic system. Therefore, a relief valve with an overpressure alarm function is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a relief valve with an overpressure alarm function to solve the problem that the relief valves currently in use cannot provide timely alarms.

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figures 1 to 5 This utility model provides an overflow valve with an overpressure alarm function, including a valve body 10; the valve body 10 has a cavity 101 and a cavity 102 in the middle for diverting liquid; the top and bottom of the valve body 10 are provided with an inlet 11 and an outlet 13; an overflow groove 103 is provided at the connection between the inlet 11 and the inside of the valve body 10; an overflow groove 104 is provided at the connection between the outlet 13 and the inside of the valve body 10; a baffle 111 is provided at the connection between one side of the inlet 11 and the valve body 10; and a pressure relief groove 112 is provided on the other side of the connection between the inlet 11 and the valve body 10.

[0023] A pressure relief block 113 is provided inside the pressure relief groove 112. The pressure relief block 113 is slidably connected to the pressure relief groove 112. A trigger rod 114 is provided at the end of the pressure relief block 113. A spring 115 is sleeved on the trigger rod 114. A branch pipe 116 is provided below the pressure relief groove 112 to connect to the liquid outlet 13.

[0024] An alarm 12 is provided on the side of the valve body 10. The trigger electrode rod of the alarm 12 extends into the pressure relief groove 112 inside the valve body 10. One end of the spring 115 is connected to the pressure relief block 113, and the other end is connected to the alarm 12. The pressure relief block 113 can compress the spring 115 to move it closer to the alarm 12. When the trigger rod 114 at the end of the pressure relief block 113 contacts the alarm 12, the alarm 12 is triggered to sound an alarm.

[0025] A branch pipe 131 is provided on one side of the outlet 13. Both the branch pipe 116 and the branch pipe 131 are connected to the outlet 13, and the branch pipe 116 and the branch pipe 131 have a certain inclination angle to ensure that the liquid can enter the outlet 13 and will not flow back.

[0026] An adjusting wheel 14 is provided on the other side of the valve body 10 for adjusting the pressure of the valve body 10. A screw 141 is provided on the adjusting wheel 14, and the screw 141 extends into the valve body 10. A limit block 142 is provided at the end of the screw 141, and a spring 143 is provided on the limit block 142. A flow divider 15 is provided inside the valve body 10. The flow divider 15 is slidably connected to the inside of the valve body 10 and is connected to the spring 143. The flow divider 15 can compress the spring 143 and move it closer to the adjusting wheel 14.

[0027] The two ends of the diversion cylinder 15 are respectively provided with sealing block 151 and sealing block 152, which are used to seal overflow groove 103 and overflow groove 104 respectively.

[0028] When liquid enters valve body 10 from inlet 11, it flows into cavity 101. As liquid enters, it pushes diverter 15 towards regulating wheel 14. The size of overflow trough 103 is adjusted via sealing block 151, regulating the water flow rate. Liquid then flows out from outlet 13 (e.g., ...). Figure 4 As shown), when the liquid flow rate is too high, the liquid pushes the sealing block 151 and sealing block 152 of the diverter cylinder 15 to block the overflow channel 103 and overflow channel 104 respectively (as shown). Figure 5 As shown), at this time, the sealing block 151 blocks the overflow groove 103. The sealing block 151 is limited by the stop block 111, and the diverter 15 cannot continue to approach the adjusting wheel 14. The liquid flows out through the pressure relief groove 112. The liquid pushes the pressure relief block 113, causing the pressure relief block 113 to move along the pressure relief groove 112. The trigger rod 114 at the tail of the pressure relief block 113 contacts the alarm light 12 to trigger the alarm. The liquid pushing the pressure relief block 113 flows from the branch pipe 116 to the outlet 13 and flows out.

[0029] The working principle and usage process of this utility model are as follows: First, liquid enters the valve body 10 through the inlet 11 and flows out through the outlet 13. When the liquid flow pressure increases, the liquid enters the cavity 101. The liquid pushes the diverter cylinder 15 to move towards the adjusting wheel 14. The size of the overflow groove 103 is adjusted by the sealing block 151, thereby regulating the liquid flow rate and pressure. When the liquid flow rate is too high, the liquid pushes the sealing blocks 151 and 152 of the diverter cylinder 15 to block the overflow groove 103 and overflow groove 104 respectively (e.g., ...). Figure 5 As shown), at this time, the sealing block 151 blocks the overflow groove 103, and the liquid flows out through the pressure relief groove 112. The liquid pushes the pressure relief block 113, causing the pressure relief block 113 to move along the pressure relief groove 112. This causes the trigger rod 114 at the tail of the pressure relief block 113 to contact the alarm light 12 and trigger the alarm. The liquid pushing the pressure relief block 113 flows from the branch pipe 116 to the outlet 13 and flows out. The alarm light promptly notifies the workers to handle the overflow valve to prevent the overflow valve from being damaged by overload for a long time.
