Description
Technical field
The utility model relates to a kind of noise reduction environmental protection pressure governor, belongs to fuel gas transmission pipe network corollary equipment technical field.
Background technique
At present, the defeated Pneumatic type of many employing middle high-pressures in gas transmission and distribution system, by pressure governor, middle high-pressure combustion gas furnishing low-pressure fuel gas is delivered to user again, in order to ensure that user uses gas safety, need in gas transmission and distribution system, low pressure line installs pressure governor, so as in automatically to regulate, the gaseous-pressure of low pressure line, thus ensure that user uses the safety low-pressure combustion gas of below setting value, but when the gas outlet of rock gas due to outlet plenum after excess pressure regulates is smaller so air-flow velocity is higher, its howling is very large.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, and provide a kind of noise reduction environmental protection pressure governor, it can reduce the howling at air outlet place, reduces its operating noise, thus reaches the object of environmental protection.
The utility model solves the problems of the technologies described above the technological scheme taked: a kind of noise reduction environmental protection pressure governor, and it comprises:
Valve body, it is provided with outlet plenum;
Denoising device, it is arranged on the gas outlet of outlet plenum, denoising device comprises bottom platen, top platen, connection part and multiple noise reduction spring, one end of connection part is connected with bottom platen, the other end is connected with top platen, form holding area between bottom platen and top platen, multiple noise reduction spring is arranged in this holding area.
Further provide a kind of concrete structure of connection part, connection part comprises screw bolt and nut, and one end of bolt is threaded connection with a nut through after bottom platen, and the other end of bolt is threaded connection with another nut through after top platen.
The further technical problem to be solved of the utility model is: in order to realize its good pressure regulating performance, this filtering separation pressure governor also comprises main pressure regulator device, main pressure regulator device comprises elasticity pressure-regulating device, epithelium, pallet, pressure regulation bar and flap, also snout cavity is provided with in described valve body, pressure modulating opening, epithelium epicoele and epithelium cavity of resorption, described tray support is on epithelium, described epithelium keeps apart epithelium epicoele and epithelium cavity of resorption, described elasticity pressure-regulating device is arranged in epithelium epicoele, and its bottom is connected on pallet, one end of described pressure regulation bar is arranged on pallet, described flap is arranged on the other end of pressure regulation bar, described epithelium cavity of resorption is connected by the gas pipeline of PRESSURE PIPE with connection outlet chamber, described pressure modulating opening is arranged between snout cavity and outlet plenum, described flap matches with pressure modulating opening to regulate the airflow clearance between flap and pressure modulating opening under the effect of the air pressure of flap in the pressure and epithelium cavity of resorption of elasticity pressure-regulating device.
After have employed technique scheme, this noise reduction environmental protection pressure governor adds a denoising device at the gas outlet of the outlet plenum of valve body, when rock gas through excess pressure regulate after due to valve port smaller so air-flow velocity is higher, when air-flow is at a high speed after multiple noise reduction spring, its howling greatly weakens, noise greatly reduces, and reaches the object of environmental protection; In addition, air pressure in epithelium cavity of resorption is identical with the air pressure in outlet plenum, the air pressure of the epithelium cavity of resorption under original state below epithelium and the pressure of elasticity pressure-regulating device balance each other, when the air pressure in outlet plenum increases, air pressure in epithelium cavity of resorption also increases, pressure regulation bar then on move, the airflow clearance between flap and pressure modulating opening diminishes, thus use intraoral air pressure decline; Otherwise the air pressure in epithelium cavity of resorption diminishes, the airflow clearance between flap and pressure modulating opening becomes large, thus the air pressure in outlet plenum promotes, and ensures that the pressure of giving vent to anger is in suitable scope, so just achieves the pressure regulating performance that it is good.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of noise reduction environmental protection pressure governor of the present utility model.
Embodiment
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, a kind of noise reduction environmental protection pressure governor, it comprises:
Valve body 1, it is provided with outlet plenum 11;
Denoising device, it is arranged on the gas outlet of outlet plenum 11, denoising device comprises bottom platen 21, top platen 22, connection part and multiple noise reduction spring 3, one end of connection part is connected with bottom platen 21, the other end is connected with top platen 22, form holding area between bottom platen 21 and top platen 22, multiple noise reduction spring 3 is arranged in this holding area.
As shown in Figure 1, connection part comprises bolt 91 and nut 92, and one end of bolt 91 is threaded connection with a nut 92 through after bottom platen 21, the other end of bolt 91 through after top platen 22 and another nut 92 be threaded connection.
As shown in Figure 1, this filtering separation pressure governor also comprises main pressure regulator device, main pressure regulator device comprises elasticity pressure-regulating device 4, epithelium 5, pallet 6, pressure regulation bar 7 and flap 8, snout cavity 12 is also provided with in valve body 1, pressure modulating opening 13, epithelium epicoele 14 and epithelium cavity of resorption 15, pallet 6 is supported on epithelium 5, epithelium 5 keeps apart epithelium epicoele 14 and epithelium cavity of resorption 15, elasticity pressure-regulating device 4 is arranged in epithelium epicoele 14, and its bottom is connected on pallet 6, one end of pressure regulation bar 7 is arranged on pallet 6, flap 8 is arranged on the other end of pressure regulation bar 7, epithelium cavity of resorption 15 is connected by the gas pipeline of PRESSURE PIPE 16 with connection outlet chamber 11, pressure modulating opening 13 is arranged between snout cavity 12 and outlet plenum 11, flap 8 matches with pressure modulating opening 13 to regulate the airflow clearance between flap 8 and pressure modulating opening 13 under the effect of the air pressure of flap 8 in the pressure and epithelium cavity of resorption 15 of elasticity pressure-regulating device 4.
Working principle of the present utility model is as follows:
This noise reduction environmental protection pressure governor adds a denoising device at the gas outlet of the outlet plenum 11 of valve body 1, when rock gas through excess pressure regulate after due to valve port smaller so air-flow velocity is higher, when air-flow is at a high speed after multiple noise reduction spring 3, its howling greatly weakens, noise greatly reduces, and reaches the object of environmental protection; In addition, air pressure in epithelium cavity of resorption 15 is identical with the air pressure in outlet plenum 11, the air pressure of the epithelium cavity of resorption 15 under original state below epithelium 5 and the pressure of elasticity pressure-regulating device 4 balance each other, when the air pressure in outlet plenum 11 increases, air pressure in epithelium cavity of resorption 15 also increases, 7, pressure regulation bar moves, and the airflow clearance between flap 8 and pressure modulating opening 13 diminishes, thus the air pressure in outlet plenum 11 is declined; Otherwise the air pressure in epithelium cavity of resorption 15 diminishes, the airflow clearance between flap 8 and pressure modulating opening 13 becomes greatly, thus the air pressure in outlet plenum 11 promotes, and ensures that the pressure of giving vent to anger is in suitable scope, so just achieves the pressure regulating performance that it is good.
