[0029] The non-coal pipeline one-way exhaust valve 100 of the utility model is installed on the exhaust component (not shown), and is used for discharging excess gas in the exhaust component.

[0030] When excess gas appears in the exhaust component, the excess gas enters the mounting groove 12 through the exhaust hole 3 and is blocked by the waterproof pad 2. Figure 3 When there is no excess gas in the exhaust component, the internal pressure of the exhaust component decreases, and the bending part 21 moves in the opposite direction of the gas outlet direction until the bending part 21 returns to the original position.

[0031] The non-coal pipeline one-way exhaust valve 100 of the utility model, by setting the mounting groove 12 for accommodating the waterproof pad 2 on the valve body 1 and the bending part 21 close to the inner circumferential side of the waterproof pad 2, and setting the exhaust hole 3 in the valve body 1 on one side of the waterproof pad 2, the excess gas in the exhaust component can be discharged along the exhaust hole 3, and the external water vapor or other liquids cannot break through the waterproof pad 2 to enter the exhaust component, which avoids the external water vapor or other liquids from entering the exhaust component, causing corrosion in the exhaust component or other adverse effects on the exhaust component.

[0032] In one embodiment, the number of waterproof pads 2 is 1. In another embodiment, please refer to Figure 3 , the waterproof pad 2 includes a first waterproof pad 21 and a second waterproof pad 22 which are sequentially stacked along the depth direction of the mounting groove 12. By setting the first waterproof pad 21 and the second waterproof pad 22, when the external water vapor or other liquid breaks through the second waterproof pad 22, the first waterproof pad 21 plays a role of blocking the external water vapor or other liquid, improving the reliability of the one-way exhaust valve 100 in use.

[0033] There are many ways to fix the first waterproof pad 21 in the mounting groove 12. In one embodiment, as shown in Figure 3 , a first clamping portion 4 is arranged in the mounting groove 12, which abuts the side of the first waterproof pad 21 away from the bottom surface of the mounting groove 12, and is used to press the first waterproof pad 21. As shown in Figure 3 , the mounting groove 12 is a circular ring, the first waterproof pad 21 and the first clamping portion 4 are both circular rings, and the diameter of the first clamping portion 4 is slightly larger than the diameter of the mounting groove 12. After installing the first waterproof pad 21 in the mounting groove 12, install the first clamping portion 4 in the mounting groove 12. Under the extrusion of the mounting groove 12, the first clamping portion 4 is firmly fixed in the mounting groove 12, and at the same time, the first waterproof pad 21 is fixed in the mounting groove 12.

[0034] By installing the annular first clamping portion 4 of the slightly larger diameter annular mounting groove 12 in the mounting groove 12, it is convenient to install and produce, and at the same time, it reduces the complexity of the valve body 1 production and reduces the production cost of the valve body 1.

[0035] Please refer to Figure 3 , in one embodiment, the position where the first waterproof pad 21 abuts against the first clamping portion 4 is provided with a first protrusion 6, the position where the first clamping portion 4 abuts against the first waterproof pad 21 is provided with a first recess, and the first protrusion 6 is limited in the first recess, so that the first waterproof pad 21 is fixed in the mounting groove 12. By setting the first protrusion 6 and the first recess, the first waterproof pad 21 is fixed more firmly, avoiding the first waterproof pad 21 from falling off.

[0036] Further, the fixing manner of the second waterproof pad 22 can refer to the first waterproof pad 21. In an embodiment, the mounting groove 12 is further provided with a second clamping portion 5, the first clamping portion 4 and the second clamping portion 5 are arranged in a stacking manner along the depth direction of the mounting groove 12, and the second waterproof pad 22 is arranged between the first clamping portion 4 and the second clamping portion 5. Under the clamping of the first clamping portion 4 and the second clamping portion 5, the second waterproof pad 22 is fixed in the mounting groove 12. In an embodiment, the second waterproof pad 22 is provided with a second protrusion 7 close to the second clamping portion 5, the second clamping portion 5 is provided with a second groove close to the second waterproof pad 22, and the second protrusion 7 is limited in the second groove to fix the second waterproof pad 22 in the mounting groove 12.

[0037] For the connection manner of the one-way exhaust valve 100 of the utility model and the exhaust component, in an embodiment, as shown in Figures 1 to 3 , the connecting portion 11 comprises a column body, an outer thread matched with an inner thread pre-provided on the exhaust component is arranged on the outer side surface of the column body, and the exhaust hole 3 is arranged on the bottom surface of the column body away from the mounting groove 12. When the exhaust valve is threadedly connected with the exhaust component, the column body extends into the exhaust component, and the gas is discharged from the exhaust hole 3 arranged on the column body.

[0038] In an embodiment, as shown in Figure 1 , the number of exhaust holes 3 is a plurality of exhaust holes arranged in a circumferential direction on the bottom surface of the column body.

[0039] The one-way exhaust valve 100 of the utility model further comprises an annular sealing gasket 8 sleeved on the column body, and the one-way exhaust valve 100 clamps the annular sealing gasket 8 with the exhaust component after being installed on the exhaust component. By arranging the annular sealing gasket 8, the water vapor or other liquid in the outside is prevented from entering the exhaust component through the gap between the one-way exhaust valve 100 and the exhaust component, and the sealing effect of the utility model in use is enhanced.

[0040] As shown in Figure 1 and Figure 3 , in an embodiment, a groove 13 perpendicular to the bottom surface of the mounting groove 12 in the depth direction is arranged on the connecting portion 11, and the exhaust hole 3 is arranged in a circumferential direction of the groove 13. When the non-coal pipeline one-way exhaust valve 100 of the utility model is installed vertically, the groove 13 can be used to accommodate the dirt discharged by the exhaust component, so as to avoid the dirt from blocking the exhaust hole 3.

[0041] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
