Description

Technical Field

[0001] The utility model belongs to the technical field of gas transmission and distribution equipment, and in particular relates to a silencer type gas pressure regulator. Background Art

[0002] In the gas transmission and distribution system, the function of the gas pressure regulator is to automatically adjust the outlet pressure to stabilize it within a certain pressure range. Due to the large size of the gas pressure regulators in large and medium-sized medium and low pressure regulating gate stations, their internal casting or design will cause eddy current chaos during operation, causing the pressure regulator to generate noise and vibration. The noise generated is transmitted to downstream users through the gas pipeline, causing noise pollution to users. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a noise-eliminating gas pressure regulator.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: it includes a shell with an air inlet and an air outlet, an inlet flange is provided at the air inlet, an outlet flange is provided at the air outlet, the air outlet and the air outlet pipe are connected by a reducer, a silencer sleeve is provided in the air outlet pipe, a front silencer hole plate is provided at the front end of the silencer sleeve, a rear silencer hole plate is provided at the rear end of the silencer sleeve, and a plurality of parallel silencer pipes are provided between the front silencer hole plate and the rear silencer hole plate.

[0005] Its additional technical feature is that the silencer sleeve is connected to the air outlet pipe by bolts, or the silencer sleeve is welded to the air outlet pipe as a whole.

[0006] The silencer type gas pressure regulator provided by the utility model is assembled, and the front end of the silencer pipe and the front silencer orifice plate, and the rear end of the silencer pipe and the rear silencer orifice plate are fully welded respectively. After the welding is completed, grinding is performed to ensure that the weld is smooth. After the silencer pipe is welded, the front silencer orifice plate and the rear silencer orifice plate are installed in the silencer sleeve and welded, and finally the silencer sleeve is fixed in the outlet pipe. During the operation of the gas pipeline equipment, when the gas pressure regulator generates noise, when the noise reaches the silencer sleeve, the noise first enters the front silencer orifice plate, so that the noise is initially decomposed, and then the noise enters the silencer pipe again, so that the noise is further decomposed, and finally the noise enters the rear silencer orifice plate again, so that the noise is further decomposed, and the noise will not be transmitted to downstream users, ensuring that the user's use is not affected. The silencer type gas pressure regulator provided by the utility model has a silencer sleeve arranged in the outlet pipe, which reduces the vortex chaos caused by the casting or design inside the gas pressure regulator, so that the gas pressure regulator runs smoothly, eliminates noise, and eliminates the vibration of the equipment. It can be widely used in large and medium-sized medium and low pressure regulating gate stations and other equipment. According to needs, the silencer sleeve is connected to the air outlet pipe by bolts, or the silencer sleeve is welded to the air outlet pipe as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The specific structure of the silencer type gas pressure regulator of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0011] like Figure 1 As shown, the utility model silencer type gas pressure regulator comprises a shell 1, the shell 1 has an air inlet 2 and an air outlet 3, the air inlet 2 is provided with an inlet flange 4, the air outlet 3 is provided with an outlet flange 5, the air outlet 3 and the air outlet pipe 6 are connected by a reducer 7, and a silencer sleeve 8 is provided in the air outlet pipe 6.

[0012] like Figure 2 As shown, a front sound-absorbing hole plate 9 is arranged at the front end of the sound-absorbing sleeve 8, and a rear sound-absorbing hole plate 10 is arranged at the rear end of the sound-absorbing sleeve 8. A plurality of parallel sound-absorbing pipes 11 are arranged between the front sound-absorbing hole plate 9 and the rear sound-absorbing hole plate 10.

[0013] like Figure 3 As shown, a plurality of parallel silencer pipes 11 are arranged in the silencer sleeve 8 .

[0014] When assembling the silencer gas pressure regulator provided by the utility model, the front end of the silencer pipe 11 and the front silencer orifice plate 9, and the rear end of the silencer pipe 11 and the rear silencer orifice plate 10 are fully welded, respectively. After the welding is completed, grinding is performed to ensure that the weld is smooth. After the silencer pipe 11 is welded, the front silencer orifice plate 9 and the rear silencer orifice plate 10 are installed in the silencer sleeve 8 and welded, and finally the silencer sleeve 8 is fixed in the outlet pipe 6. When the gas pipeline equipment is in operation, when the gas pressure regulator generates noise, when the noise reaches the silencer sleeve 8, the noise first enters the front silencer orifice plate 9, so that the noise is initially decomposed, and then the noise enters the silencer pipe 11, so that the noise is further decomposed, and finally the noise enters the rear silencer orifice plate 10, so that the noise is further decomposed, and the noise will not be transmitted to downstream users, ensuring that the user's use is not affected. The utility model provides a silencer type gas pressure regulator, in which a silencer sleeve 8 is arranged inside the gas outlet pipe 6, which reduces the eddy current disorder caused by the casting or design inside the gas pressure regulator, makes the gas pressure regulator run smoothly, eliminates the noise, eliminates the vibration of the equipment, and can be widely used in large and medium-sized medium and low pressure regulating gate stations and other equipment. According to the needs, the silencer sleeve 8 is connected to the gas outlet pipe 6 by bolts, or the silencer sleeve 8 is welded to the gas outlet pipe 6 as a whole.
