Abstract
The special bleeding device of a kind of pressure regulating cabinet is a kind of pressure bleeding device for natural gas pressure regulating cabinet.Adopt novel light PPR pipe, make shaping bleeding device, when gas pipeline diffuses, carry out metal be flexible coupling with gas-fired equipment blowdown valve, start a high position and diffuse, exhaust stack top is provided with many places and diffuses hole, reduces and diffuses noise.There is the noise pollution and pollution of atmosphere that reduce and diffuse in process, improve the Security given out of gas, be easy to dismounting, be convenient to the features such as application.
Description
(1) technical field
The utility model relates to a kind of pressure bleeding device for natural gas pressure regulating cabinet.
(2) background technique
Diffuse the primary link that step-down is gas industry operation under pressure, in operation process in the past, integrated maintenance person sets up warning region around pressure regulating cabinet, opens middle pressure cock and diffuses.Diffuse that process noise is large, combustion gas is not easily spread, easily surrounding enviroment are polluted, and need many people safety custody, have a strong impact on working efficiency.
(3) model utility content
The purpose of this utility model is that reducing pipeline pressure diffuses noise pollution in process and pollution of atmosphere, improves the Security given out of gas.
The utility model solves the technological scheme that its technical problem adopts:
The bleeding device that a kind of pressure regulating cabinet is special, by PPR exhaust stack, holding clamp, DN15 valve, DN15 metal bellows, sound attenuation hole is formed, it is characterized in that: PPR exhaust stack is connected with holding clamp, and with holding clamp, exhaust stack is fixed on pressure regulating cabinet edge, DN15 metal bellows is connected with pressure regulating cabinet blowdown valve, DN15 valve is connected with PPR exhaust stack with DN15 metal bellows respectively, and PPR exhaust stack upper end is provided with sound attenuation hole.
Preferably, holding clamp material is 45# steel, and top installs equilibrium block additional, to ensure and pressure regulating cabinet edge stable connection, does not produce swing, reach the effect of whole machine balancing when diffusing.
Preferably, PPR exhaust stack is 1.5 meters of PPR materials, diffuses in process and combustion gas directly can be diffused to above position, pressure regulating cabinet top, be easy to combustion gas diffusion in an atmosphere, reduce the environmetal impact to neighbouring resident.
Preferably, PPR exhaust stack adopts PPR pipe, has price economy, stable performance, heat-and corrosion-resistant, safe and reliable advantage.
The beneficial effects of the utility model are: reduce the noise pollution and pollution of atmosphere of diffusing in process, improve the Security given out of gas, be easy to dismounting, be convenient to application.
(4) accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
1 be PPR exhaust stack, 2 be holding clamp in figure, 3 be DN15 valve, 4 be DN15 metal bellows, 5 for sound attenuation hole.
(5) embodiment
The PPR exhaust stack 1 of 1.5 Miho Dockyard N20 welds two shaping threeways of DN15, and at end welding end cap, two threeways place, DN15 valve 3 is installed, is connected with DN15 metal bellows 4 with outer silk; PPR exhaust stack 1 upper end is provided with sound attenuation hole 5.
Before pressure regulating cabinet diffuses, PPR exhaust stack 1 is stuck in the pipe clamp of holding clamp 2, guarantee that PPR exhaust stack 1 upper end exceeds voltage adjusting device, holding clamp 2 is arranged on pressure regulating cabinet edge, the other end of DN15 metal bellows 4 is connected with voltage adjusting device blowdown valve, open and connect the DN15 valve 3 of DN15 metal bellows 4 front end, open blowdown valve afterwards and carry out a combustion gas high position and diffuse.
Holding clamp 2 material is 45# steel, and top installs equilibrium block additional, to ensure and pressure regulating cabinet edge stable connection, does not produce swing, reach the effect of whole machine balancing when diffusing.PPR exhaust stack 1 adopts PPR pipe.
