DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 5, A natural gas pressure regulating device, comprising an air vent cylinder 1, an inlet pipe 2, an outlet pipe 3, a regulating component, a gas baffle 4, a positioning component and an opening and closing component. A through groove is provided at the top end of the air vent cylinder 1. The inlet pipe 2 communicates with the side surface of the air vent cylinder 1, and the outlet pipe 3 communicates with the side surface of the air vent cylinder 1. There are two regulating components, and the two regulating components are arranged at the top end of the air vent cylinder 1. The gas baffle 4 is arranged on the regulating component, and a plurality of positioning grooves and ventilation holes are provided on the side surface of the gas baffle 4. The positioning component is arranged at the bottom end of the air vent cylinder 1 for positioning the gas baffle 4. The opening and closing component is arranged on the side surface of the air vent cylinder 1 for opening and closing the ventilation holes of the gas baffle 4. Through the opening and closing component, a plurality of ventilation holes of the gas baffle 4 can be blocked and opened, so as to control the output of natural gas. And through the regulating component and the positioning component, the gas baffle 4 is driven to move up and down, so that natural gas flows out between the gas baffle 4 and the air vent cylinder 1.

[0027] In this embodiment, referring to Figure 2 , The regulating component includes a support cover 101, a reciprocating lead screw 102, a lead screw nut 103, a connecting frame 104 and a turntable 105. The support cover 101 is fixedly installed at the top end of the air vent cylinder 1. The reciprocating lead screw 102 is rotatably installed in the support cover 101. The lead screw nut 103 is threadedly connected to the reciprocating lead screw 102. One end of the connecting frame 104 is fixedly installed on the lead screw nut 103, and the other end of the connecting frame 104 is fixedly installed at the top end of the gas baffle 4. The turntable 105 is fixedly installed at the top end of the reciprocating lead screw 102. By rotating the turntable 105, the reciprocating lead screw 102 rotates, thereby driving the lead screw nut 103 and the connecting frame 104 to move up and down, and the connecting frame 104 drives the gas baffle 4 to move up and down.

[0028] In this embodiment, referring to Figure 3 , The positioning component includes a positioning frame 201, a sliding rod 202, a moving block 203, a positioning rod 204 and a bolt 205. There are two positioning frames 201, and the two positioning frames 201 are fixedly installed at the top end of the air vent cylinder 1, and a threaded hole is provided at the top end of the positioning frame 201. There are two sliding rods 202, and the two sliding rods 202 are respectively fixedly installed on the two positioning frames 201. The moving block 203 is slidably installed on the two sliding rods 202, and a threaded hole is provided at the top end of the moving block 203. There are two positioning rods 204, and the two positioning rods 204 are fixedly installed at the bottom end of the moving block 203. The bolt 205 is threadedly connected to the threaded hole. By sliding the position of the moving block 203 on the sliding rod 202, the positioning rod 204 is driven to insert into the positioning groove of the gas baffle 4, and then the thread is threadedly connected into the threaded holes of the moving block 203 and the positioning frame 201 for fixation.

[0029] In this embodiment, referring to Figure 4, the opening and closing assembly includes an opening and closing plate 301, a fixing bracket 302, a limiting rod 303 and a handle 304. The opening and closing plate 301 is slidably installed at the ventilation hole on the side of the air baffle 4. A number of limiting grooves are provided at the top of the opening and closing plate 301, and the opening and closing plate 301 is slidably installed through the side of the ventilation cylinder 1. The fixing bracket 302 is fixedly installed on the side of the ventilation cylinder 1. The limiting rod 303 is slidably installed through the fixing bracket 302. The handle 304 is fixedly installed on the side of the opening and closing plate 301. Pull the handle 304 to make the opening and closing plate 301 slide on the side of the air baffle 4, so as to block and open the ventilation hole of the air baffle 4, and release the natural gas. And by moving the limiting rod 303, it can be inserted into the groove of the opening and closing plate 301 to fix it.

[0030] In this embodiment, referring to Figure 2 and Figure 3 , when the positioning rod 204 is inserted into the positioning groove of the air baffle 4, the threaded hole of the moving block 203 and the threaded hole of the positioning bracket 201 are in the same vertical position. Thus, when the positioning rod 204 is inserted into the positioning groove, the moving block 203 and the positioning rod 204 can be fixed on the positioning bracket 201 to prevent forward and backward movement.

[0031] In this embodiment, referring to Figure 5 , the air baffle 4 can be slidably attached in the through groove of the ventilation cylinder 1, so as to prevent natural gas leakage when the air baffle 4 is lifted or lowered.

[0032] In summary, when the natural gas pressure regulating device is adjusted, natural gas is first input into the intake pipe 2. When controlling the volume of natural gas passing through, the pull handle 304 can be pulled to slide the opening and closing plate 301, exposing several ventilation holes. Then, according to the amount of natural gas required, the natural gas can flow out through the ventilation holes. When the number of opened ventilation holes is determined, the limit rod 303 can be moved and inserted into the corresponding groove of the opening and closing plate 301, and then the opening and closing plate 301 is fixed. If more natural gas needs to pass through, the opening and closing plate 301 can be pulled out of the ventilation cylinder 1, and then the turntable 105 is rotated to rotate the reciprocating lead screw 102, thereby driving the lead screw nut 103 and the connecting frame 104 to move up and down. The connecting frame 104 drives the air baffle 4 to move up and down, and the natural gas can flow out through the gap between the air baffle 4 and the ventilation cylinder 1. Moreover, the size of the gap can be adjusted according to the height of the air baffle 4 moving up and down, so as to control the volume of natural gas passing through. After the air baffle 4 moves up and down, the moving block 203 can be slid, the positioning rod 204 is inserted into the corresponding positioning groove, and then the bolt 205 is threadedly connected into the threaded holes of the moving block 203 and the positioning frame 201 for fixation. It should be added that the distances between several positioning grooves of the air baffle 4 are the same. Therefore, the volume of natural gas passing through can be roughly determined and adjusted according to the positioning grooves. In addition, the air baffle 4 fits and slides with the inner side wall of the ventilation cylinder 1, thus avoiding the leakage of natural gas when the air baffle 4 moves up and down.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
