Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a technical solution: a municipal gas pipe valve, comprising a gas pipe 1, a sealing assembly 2 is arranged on the right side of the gas pipe 1;

[0032] The sealing assembly 2 includes a fixing rod 201, a connecting rod 202 and a fixing screw 203. The fixing rod 201 is arranged on the right side of the gas pipe 1, and the connecting rod 202 is connected inside the fixing rod 201. The fixing screw 203 is penetrated in the middle of the fixing rod 201 and the connecting rod 202, and a sealing ring 204 is arranged on the inner wall end of the connecting rod 202.

[0033] The right end of the sealing component 2 is connected with a threaded pipe 3; a fixed pipe 4 is arranged on the left side of the gas pipe 1, a valve 5 is passed through the middle of the gas pipe 1, and a handle 6 is connected to the top of the valve 5, and a thickening component 7 is installed on the upper end of the handle 6, and a pushing component 8 is arranged at the front end of the fixed pipe 4. Specifically, firstly, a sealing component 2 is arranged in the middle of the gas pipe 1 and the threaded pipe 3, so that when another set of connecting pipes is connected to the threaded pipe 3, the connection is sealed by the sealing component 2, which effectively prevents gas leakage when the gas pipe is connected. The connecting rod 202 is stretched outward from the fixed rod 201, and the sealing ring 204 can be connected to the connection. The fixing screw 203 is passed through the middle of the connecting rod 202 and the fixing rod 201 for positioning and locking. The sealing ring 204 is set at the gap between the threaded pipe 3 and the gas pipe 1 for sealing. Then, the pushing component 8 is opened to move the valve 5 in the middle of the fixing pipe 4 through the movement of the handle 6. The valve 5 can be opened and closed electrically. The upper end of the handle 6 is provided with a thickening component 7, which is convenient for threading the threaded rod 703 of the thickened handle 701 on the handle 6, reinforcing the body of the handle 6 to prevent the user from rotating and moving the handle 6 and causing breakage. The thickened handle 701 is fixed by the anti-slip pattern 702. 1 is subjected to anti-skid treatment to prevent the thickened handle 701 from slipping and loosening during the pushing process. The clamp 802 is clamped on the thickened handle 701 and the handle 6, and the electric telescopic rod 801 of the pushing component 8 can be telescoped back and forth. The thickened handle 701 and the handle 6 are electrically opened and closed by the electric telescopic rod 801 at the rear end of the clamp 802, which saves the user from manually opening and closing the valve 5. The anti-skid teeth 803 are arranged on the upper and lower sides of the clamp 802 to effectively prevent the thickened handle 701 and the handle 6 from sliding after the clamp 802 is clamped. Through this technical solution, the problem of the valve 5 being in operation is solved. In order to solve the problem that gaps are prone to appear at the connection, which affects the gas transportation, a sealing component 2 is provided in the middle of the gas pipe 1 and the threaded pipe 3, so that when another set of connecting pipes is connected to the threaded pipe 3, the connection is sealed by the sealing component 2, which effectively prevents gas leakage when the gas pipe is connected. The connecting rod 202 is stretched outward from the fixed rod 201, and the sealing ring 204 can be used to seal the connection. Finally, the fixing screw 203 is inserted into the middle of the connecting rod 202 and the fixed rod 201 for positioning and locking. The sealing ring 204 is set at the gap between the threaded pipe 3 and the gas pipe 1 for sealing.

[0034] Further, such as Figure 1 and Figure 2The figure shows that the thickening component 7 also includes a thickened handle 701, anti-skid patterns 702 and a threaded rod 703. The thickened handle 701 is installed on the upper end of the handle 6, and the middle part of the thickened handle 701 is provided with anti-skid patterns 702. The bottom end of the thickened handle 701 is provided with a threaded rod 703. The advantage of this technical solution is that the thickening component 7 is provided on the upper end of the handle 6, so that the threaded rod 703 of the thickened handle 701 can be threadedly arranged on the handle 6 to reinforce the body of the handle 6, thereby preventing the user from rotating and moving the handle 6 and causing breakage. The anti-skid patterns 702 are used to perform anti-skid treatment on the thickened handle 701 to prevent the thickened handle 701 from slipping and loosening during the pushing process.

[0035] The above solution still has the problem that it is not convenient to automatically push the handle 6 and the thickened handle 701. Figure 1 and Figure 4 As shown: in this solution, the push assembly 8 includes an electric telescopic rod 801, a clamp 802 and anti-slip teeth 803. The front end of the fixed tube 4 is provided with the electric telescopic rod 801, and the inner wall end of the electric telescopic rod 801 is connected with the clamp 802, and the inner wall end of the clamp 802 is provided with anti-slip teeth 803. The clamp 802 is clamped on the thickened handle 701 and the handle 6, and the electric telescopic rod 801 of the push assembly 8 can be telescoped back and forth. The thickened handle 701 and the handle 6 are electrically opened and closed by the electric telescopic rod 801 at the rear end of the clamp 802, which saves the user from manually opening and closing the valve 5. The anti-slip teeth 803 are provided on the upper and lower sides of the clamp 802, which effectively prevents the thickened handle 701 and the handle 6 from sliding after the clamp 802 is clamped.

[0038] First, a sealing component 2 is provided in the middle of the gas pipe 1 and the threaded pipe 3, so that when another set of connecting pipes is connected to the threaded pipe 3, the connection is sealed by the sealing component 2, which effectively prevents gas leakage when the gas pipe is connected. The connecting rod 202 is stretched from the inside of the fixed rod 201 to the outside, and the sealing ring 204 can be used to seal the connection. Finally, the fixing screw 203 is passed through the middle of the connecting rod 202 and the fixed rod 201 for positioning and locking. The sealing ring 204 is provided in the gap between the threaded pipe 3 and the gas pipe 1 for sealing. Then, the pushing component 8 is opened to move the valve 5 in the middle of the fixed pipe 4 through the movement of the handle 6, and the valve 5 can be electrically opened and closed. A thickening component 7 is provided at the upper end of the handle 6, which is convenient for thickening the handle 70 The threaded rod 703 of 1 is threadedly arranged on the handle 6 to reinforce the body of the handle 6 to prevent the user from rotating and moving the handle 6 and causing breakage. The thickened handle 701 is anti-slipped by the anti-slip groove 702 to prevent the thickened handle 701 from slipping and loosening during the pushing process. The clamp 802 is clamped on the thickened handle 701 and the handle 6, and the electric telescopic rod 801 of the pushing component 8 can be telescoped back and forth. The thickened handle 701 and the handle 6 are electrically opened and closed by the electric telescopic rod 801 at the rear end of the clamp 802, which saves the user from manually opening and closing the valve 5. Anti-slip teeth 803 are provided on the upper and lower sides of the clamp 802 to effectively prevent the thickened handle 701 and the handle 6 from slipping after the clamp 802 is clamped.
