Abstract
The utility model discloses a large -traffic relief pressure valve, it includes the valve pocket, is connected with inlet channel and air outlet channel on the valve pocket, is equipped with first order decompression structure between the lower extreme of valve pocket and the inlet channel, and the one -level decompression gas outlet of first order decompression structure communicates with each other through valve port and valve pocket, and upper end in the valve pocket is equipped with carries out the second level decompression structure controlled to the airflow through the valve port, and setting that the structure is upper and lower range is reduced pressure on the relief pressure valve in first order decompression structure and the second level. The utility model discloses can automatically regulated decompression, firm output flow, this valve novel structure, enable with at home with external most gas cylinder and gas utensil on, coordinate unique doublestage decompression structure, have structure uniqueness, doublestage decompression steady voltage, flow greatly, characteristics that the market commonality is strong.
Description
[technical field]
The utility model relates to a kind of high-flow pressure reducing valve.
[background technique]
Although the design of family expenses reduction valve is on the market had nothing in common with each other, all there is the little namely problem that flow is inadequate of fire or flow foot in the overwhelming majority, but other performance has exceeded the problem of NBS.General family expenses reduction valve is only by single-stage pressure reducing, and valve port aperture is little, and valve port opening is narrow, and these factors have and have influence on the stability of delivery pressure and the size of flow.
[model utility content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, there is provided one automatically can regulate decompression, stablize output flow, this valve arrangement is novel, can be used on home and overseas major part gas cylinder and gas utensil, coordinate unique two stage pressure reducing structure, have that structure uniqueness, two stage pressure reducing voltage stabilizing, flow are large, market highly versatile high-flow pressure reducing valve.
The purpose of this utility model is achieved in that
A kind of high-flow pressure reducing valve, it comprises valve pocket, valve pocket is connected with gas-entered passageway and outlet passageway, it is characterized in that being provided with first order pressure reduction structure between the lower end of described valve pocket and gas-entered passageway, the one-level pressure vent of first order pressure reduction structure is communicated with valve pocket by valve port, upper end in described valve pocket is provided with the second level pressure reduction structure controlled the throughput by valve port, and described first order pressure reduction structure and second level pressure reduction structure are being arranged on reduction valve of upper and lower arrangement.
A kind of high-flow pressure reducing valve as above, it is characterized in that described first order pressure reduction structure comprises first order Pressure relief valve seat, first order Pressure relief valve seat is provided with first order diaphragm unit, one end of first order diaphragm unit is provided with first order spool, the upper end of first order spool is provided with the plug that can be against first order reduction valve intake valve port, and the other end of first order diaphragm unit is provided with first order reduction valve Returnning spring.
A kind of high-flow pressure reducing valve as above, it is characterized in that described second level pressure reduction structure comprises second level Pressure relief valve seat, second level Pressure relief valve seat is provided with second level diaphragm unit, one end of diaphragm unit is provided with second level spool, spool lower end, the second level is connected with lever, the other end of lever is provided with the valve pad that can be against valve port, and the other end of second level diaphragm unit is provided with second level reduction valve Returnning spring.
A kind of high-flow pressure reducing valve as above, is characterized in that the poppet shaft of the first order spool of described first order pressure reduction structure and the second level spool of second level pressure reduction structure is arranged for coaxial.
The utility model has the following advantages:
1, by the pressure regulation of double-stage pressure-regulation mechanism, delivery pressure will can be stablized with accurate than general single-stage pressure-regulating device more; In addition, as figure finds out, the valve port aperture of second depressurized mechanism is large, is 3 ~ 5 times of general single-stage pressure reducing valve, and valve rod hunting range is large, and such structure, can be reduction valve and export sizable flow.
2. in addition, the envelope valve arrangement of lever and valve pad realizes closing performance to meet standard, the key component that flow is large, valve rod is equipped with the sealing plate that can freely swing, when reduction valve reaches cut out condition, lever swing, enable valve pad entirely with valve port pressing, reach the function of close port.
3. in addition, from outward appearance, general two stage pressure reducing valves be that build is huger, outward appearance is more eccentric.But this reduction valve of design green for a long time, more petite than general two stage pressure reducing valves, outward appearance is also comparatively exquisite, this mainly gives the credit to the coaxial design of two stage pressure reducing valves, and one-level is on same axle center with the mandrel axis of second depressurized valve, is also on the central axis of whole reduction valve, the reduction valve designed like this, compact structure, outward appearance is exquisite, also has symmetrical aesthetic feeling simultaneously.
4, the utility model automatically can regulate decompression, stablize output flow, this valve arrangement is novel, can be used on home and overseas major part gas cylinder and gas utensil, coordinate unique two stage pressure reducing structure, have that structure uniqueness, two stage pressure reducing voltage stabilizing, flow are large, the feature of market highly versatile.
