Description
Technical field
It the utility model is related to city gas transmission pipeline network corollary equipment technical field, especially a kind of gas safe diffusion
Valve.
Background technology
Gas is the important energy source of China or even countries in the world, and it mainly includes natural gas, liquefied petroleum gas, coal system
Gas and artificial coal gas etc..Gas not only turns into the main energy sources of China's resident living as important basic energy resource at present,
Be also widely used for the every field such as heating, refrigeration, generating, automobile, with China's economy and gas cause it is continuous to
Preceding development, people propose higher requirement to the quality, performance and security of gas-fired equipment, market need it is safer, efficient,
The gas-fired equipment of energy-saving and environmental protection.Continually developing China has the equipment such as the fuel gas pressure-regulating box of independent intellectual property right, to improve China
The competitiveness of gas equipment supply enterprise.
In the running of fuel gas pressure-regulating box equipment, pressure or the situation of flow moment increase occurs in downstream sometimes,
To prevent upstream device from influenceing safe handling because pressure increases, the setting of voltage adjusting device cut-out pressure is not increased in downstream pressure
Before value, voltage adjusting device can release portion gas to reduce the pressure in pipeline by Safety relief valve.Existing Safety relief valve
Have that some structures are complex, volume is larger, but security is fine；Certain structures are simple, compact, but for pressure
Relief situation is bad, so needing a kind of compact, compact-sized, conveniently maintenance is changed, safe and reliable, pressure relief capability is stronger
Safety relief valve.
Utility model content
The technical problems to be solved in the utility model is：Overcome deficiency in the prior art, there is provided a kind of gas safe is put
Dissipate valve.
Technical scheme is used by the utility model solves its technical problem：A kind of gas safe diffusion valve, including tool
There is the T-valve body of three passages, three passages are respectively an inlet channel and two outlet passageways, and the outlet passageway is close
Valve port is provided with body cavity center, valve port is outwards disposed with spring base, spring, spring bearer plate and outlet connecting plate, bullet
Spring abutment seals the valve pad of valve port through hole towards being connected with the side of valve port, and spring bearer plate withstands spring base to compress valve through spring
Pad, outlet connecting plate are arranged on the end of outlet passageway.
Further, the valve pad is mounted elastically by fixed screw.
Further, the coefficient of elasticity of spring is identical in two outlet passageways.In this way, two outlet passageways diffuse
The port of export to diffuse pressure value identical, when an outlet passageway inner part, which breaks down, to work, one outlet of the other end
The discharging opening end of passage can continue to diffuse pressure.
Further, the coefficient of elasticity of spring is more than the elasticity system of spring in another outlet passageway in an outlet passageway
Number.In this way, the discharging opening end of two outlet passageways, which has two kinds, diffuses pressure value, diffused when gas pressure reaches relatively low
During pressure, one end outlet passageway diffuses, and such as pressure rise, reaches higher when diffusing pressure, other end outlet pipe also diffuses.
The beneficial effects of the utility model are：The utility model have compact, it is compact-sized, settable two kinds diffuse
The features such as pressure value, convenient maintenance are changed, are safe and reliable.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1. valve body, 2. valve ports, 3. spring bases, 4. springs, 5. spring bearer plates, 6. outlet connecting plates, 7. valve pads, 8.
Fixed screw, 11. inlet channels, 12. outlet passageways.
Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of gas safe diffusion valve as shown in Figure 1, including the T-valve body 1 with three passages, three passage difference
For an inlet channel 11 and two outlet passageways 12, outlet passageway 12 is provided with valve port 2, valve port 2 at the lumen centers of valve body 1
Outwards it is disposed with spring base 3, spring 4, spring bearer plate 5 and outlet connecting plate 6,4, spring is towards connecting on the side of valve port 2
The valve pad 7 for sealing the through hole of valve port 2 is connected to, valve pad is arranged on spring base 3 by fixed screw 8, and spring bearer plate 5 pushes up through spring 4
Firmly for spring base 3 to compress valve pad 7, outlet connecting plate 6 is arranged on the end of outlet passageway 12.
The gas safe diffusion valve is mainly installed in voltage adjusting device at the outlet conduit in gas pressure regulator, governor downstream, and gas leads to
After crossing gas pressure regulator, governor, if downstream pressure exceedes the setting pressure of pressure regulator, over-pressure gas will be entered by the T-shaped diffusion valve
Exhaust stack leads to air.The discharging opening end of two outlet passageways 12, it is settable it is identical diffuse pressure value, when an outlet passageway
12 inner parts break down when can not work, and the discharging opening end of one outlet passageway 12 of the other end can continue to diffuse pressure；
It can set the discharging opening end of two outlet passageways 12 that there are two kinds and diffuse pressure value, pressure is diffused when gas pressure reaches relatively low
During force value, one end outlet passageway 12 diffuses, and such as pressure rise, reaches higher when diffusing pressure value, other end outlet pipe 12
Diffuse.
For above-mentioned embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this skill
The personage of art can understand content of the present utility model and be carried out, and protection model of the present utility model can not be limited with this
Enclose, all equivalent change or modifications made according to the utility model Spirit Essence, should all cover in protection model of the present utility model
In enclosing.
