[0026] like Figures 1-4As shown, the spark arrester with explosion relief function includes a body 1, a slow-release cover 2, an explosion relief plate 4 and a spark arresting component 8. A slow-release cover 2 is provided at each end of the body 1, and an opening is provided on one side of the body 1, in which the explosion relief plate 4 is installed. A maintenance door 5 is provided on the other side of the body 1, and one side of the maintenance door 5 is hinged to the periphery of the body 1 through a hinge, and the other side of the maintenance door 5 is detachably connected to the periphery of the body 1 through a fixing member 6. The spark arresting component 8 is concentrically provided in the body 1, and the spark is conveniently accessed through the maintenance door 5. The collecting component 8 is disassembled and maintained to prevent dust accumulation on the spark collecting component 8. A hole is opened in the main body 1 and an explosion-proof plate 4 is set. The explosion-proof function of the explosion-proof plate 4 can prevent sparks from igniting dust on the spark collecting component 8, causing internal explosions and causing damage to equipment and personnel around the valve. The explosion-proof function principle of the explosion-proof plate 4 is that the structural strength of the explosion-proof plate 4 is less than the structural strength of the main body 1 and the series pipe. When an explosion occurs, the explosion-proof plate 4 is destroyed to relieve pressure and prevent impact on the pipe.
[0027] The cross section of the slow-release cover 2 is a trapezoidal structure. The large end of the slow-release cover 2 is installed to one end of the main body 1. The small end of the slow-release cover 2 is connected to the external pipe through the flange 3, and a sealing gasket 7 is provided on the flange 3 to ensure the sealing performance of this part. The trapezoidal structure of the slow-release cover 2 reduces the pressure and speed of the medium entering the main body 1, and increases the pressure and speed of the medium discharged from the main body 1, so as to facilitate the spark capture component 8 to intercept the spark point.
[0028] The fixing member 6 includes a first support plate 61, a second support plate 62 and a fixing bolt 63. The first support plate 61 is fixedly mounted on the body 1, and the second support plate 62 is fixedly mounted on the maintenance door 5. The second support plate 62 is provided with an opening. The fixing bolt 63 is installed on the first support plate 61. The periphery of the fixing bolt 63 can be located in the opening. The nut is threadedly connected to the periphery of the fixing bolt 63 and abuts against one side of the second support plate 62, which is used to fix the relative positions of the first support plate 61 and the second support plate 62, so as to facilitate the connection between the maintenance door 5 and the body 1 by the staff.
[0029] The spark collecting component 8 is installed inside the main body 1 through the support frame 9, and the support frame 9 is a frame structure. The support frame 9 does not contact the explosion venting piece 4. The outer periphery of the support frame 9 abuts against the side wall of the main body 1 to prevent the installation of the spark collecting component 8 from interfering with the explosion venting piece 4. The outer periphery of the spark collecting component 8 is slidably connected to the support frame 9, and the spark collecting component 8 of this embodiment is a 60-mesh stainless steel wire mesh, which is a blocking structure in the main body 1. The whole is made of 304 stainless steel. The spark collecting component 8 is used to block and extinguish sparks.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
