[0029] As shown in Figures 1 to 7 An embodiment of the safety valve of the present application comprises: a valve body 1, a liquid discharge pipe 101, a guide-out assembly 2, a sound warning assembly 3.

[0030] As shown in Figures 1 to 4 One side of the valve body 1 is integrally formed with the liquid discharge pipe 101. This facilitates the fluid medium in the valve body 1 to be discharged along the liquid discharge pipe 101.

[0031] As shown in Figures 1 to 4 The upper part of the valve body 1 is integrally formed with a liquid inlet pipe 102. This facilitates the fluid medium to be conveyed into the valve body 1 along the liquid inlet pipe 102.

[0032] As shown in Figures 1 to 4 The guide-out assembly 2 is fixedly assembled on one side of the valve body 1, and the guide-out assembly 2 comprises a guide liquid pipe 201, which is in communication with the liquid discharge pipe 101. This facilitates the fluid medium discharged at the liquid discharge pipe 101 to be guided out along the guide liquid pipe 201.

[0033] As shown in Figures 1 to 2 A sealing gasket 202 is arranged between the guide liquid pipe 201 and the liquid discharge pipe 101. The sealing gasket 202 plays a sealing and limiting role on the guide liquid pipe 201 and the liquid discharge pipe 101.

[0034] As shown in Figures 1 to 4 Both ends of the guide liquid pipe 201 are fixedly connected with flanges 203. The flanges 203 are assembled and fixed to limit the assembly of the guide liquid pipe 201 and the liquid discharge pipe 101.

[0035] As shown in Figures 1 to 4 A plurality of assembly bolts 204 are fixedly connected between the flanges 203 and the liquid discharge pipe 101. The assembly bolts 204 play a connecting and fixing role on the flanges 203 and the liquid discharge pipe 101.

[0036] As shown in Figures 2 to 5As shown, the sound warning component 3 is fixedly assembled on one side of the liquid discharge pipe 101, and the sound warning component 3 comprises a driving shaft 301, which is rotatably assembled in the guide liquid pipe 201. The driving shaft 301 plays a role of assembling and fixing the connecting inner cylinder 307, and rotates the driving shaft 301 through the rotating mode of the plurality of liquid guide plates 302 with the fluid medium flowing in the guide liquid pipe 201, so as to facilitate the rotation driving control of the fixed ring 303 by the driving shaft 301.

[0037] As shown in the Figures 2 to 3 As shown, the outer side of the guide liquid pipe 201 is integrally formed with a fixed outer ring 306, and both ends of the driving shaft 301 are rotatably connected with the fixed outer ring 306. The fixed outer ring 306 plays a role of assembling and fixing the driving shaft 301 and the sound plate 305.

[0038] As shown in the Figures 4 to 5 As shown, a plurality of uniformly distributed liquid guide plates 302 are fixedly assembled on one side of the driving shaft 301 in the guide liquid pipe 201. The plurality of liquid guide plates 302 rotate the driving shaft 301 through the rotating mode of the plurality of liquid guide plates 302 with the fluid medium flowing in the guide liquid pipe 201.

[0039] As shown in the Figures 4 to 5 As shown, a connecting inner cylinder 307 is fixedly connected between the plurality of liquid guide plates 302, and the connecting inner cylinder 307 is fixedly sleeved on the outer side of the driving shaft 301. The connecting inner cylinder 307 plays a role of connecting the driving shaft 301 and the plurality of liquid guide plates 302.

[0040] As shown in the Figures 2 to 3 As shown, a fixed ring 303 is fixedly connected to one end of the driving shaft 301 outside the guide liquid pipe 201. The fixed ring 303 plays a role of connecting the liquid guide plate 302 and the connecting rope 308, so that the sound ball 304 can rotate synchronously with the rotation of the driving shaft 301 under the action of the connecting rope 308 and the fixed ring 303.

[0041] As shown in the Figures 2 to 3 As shown, a pair of sound balls 304 are fixedly connected to the outer side of the driving shaft 301. The pair of sound balls 304 generate a warning prompt sound through the mutual impact with the sound plate 305, so as to facilitate the warning prompt of whether there is fluid medium conduction in the guide liquid pipe 201.

[0042] As shown in the Figures 6 to 7 As shown, a connecting rope 308 is fixedly connected between the pair of sound balls 304 and the fixed ring 303. The connecting rope 308 plays a role of connecting the sound ball 304 and the fixed ring 303.

[0043] Specifically, the length of the connecting rope 308 is greater than the distance between the sounding plate 305 and the axis of the driving shaft 301. This facilitates the sounding ball 304 to collide with the sounding plate 305 under the action of the connecting rope 308, thereby facilitating the generation of a warning prompt sound.

[0044] Among them, the pair of sounding balls 304 are hollowly arranged, and a plurality of collision balls 309 are arranged in the pair of sounding balls 304. The warning sound is generated by the swinging and collision of the plurality of collision balls 309 in the cavity of the sounding ball 304.

[0045] In addition, the outer side of the pair of sounding balls 304 is provided with a ventilation sounding hole. By providing the ventilation sounding hole, it is convenient for external air to enter the sounding ball 304 through the ventilation sounding hole, thereby ensuring that the plurality of collision balls 309 collide under the action of the airflow and external force.

[0046] As shown in Figures 6 to 7 The side of the guide liquid pipe 201 is fixedly assembled with the sounding plate 305, and the sounding plate 305 is arranged in cooperation with the sounding ball 304. The warning prompt sound is generated by the collision of the sounding plate 305 and the sounding ball 304.

[0047] As shown in Figures 6 to 7 The side of the sounding plate 305 close to the sounding ball 304 is fixedly connected with the impact plate 310. The warning prompt is performed by the collision of the sounding plate 305 and the impact plate 310. The sounding cavity is formed between the impact plate 310 and the sounding plate 305. The warning prompt sound generated by the collision of the sounding ball 304 and the sounding plate 305 is improved by setting the sounding.

[0048] Specifically, in use, the valve body 1 is assembled in the equipment or fluid pipeline system to be protected through the liquid inlet pipe 102. When the fluid medium is in an overpressure state, the fluid medium can enter the valve body 1 through the liquid inlet pipe 102 and be discharged through the liquid outlet pipe 101, and be transported and discharged through the guide liquid pipe 201.

[0049] The plurality of groups of flow guide liquid plates 302 in the guide liquid pipe 201 can rotate with the flow of the fluid medium. The rotation of the plurality of groups of flow guide liquid plates 302 drives the driving shaft 301 to rotate synchronously, so that the driving shaft 301 can drive the sounding ball 304 to rotate under the action of the fixed sleeve ring 303 and the connecting rope 308. In the rotating process of the sounding ball 304, the external airflow can enter the sounding ball 304 through the ventilation sounding hole, and the plurality of collision balls 309 can collide with the sounding ball 304 under the action of the airflow, thereby generating a warning prompt sound. In addition, the sounding ball 304 can collide with the impact plate 310 in the rotating process, and the sounding ball 304 collides with the impact plate 310 to assist in generating a warning prompt sound.
