Description
Technical field
The utility model relates to decompressor technical field, particularly a kind of high sensitivity decompressor.
Background technique
Decompressor is that pressurized gas are reduced to low-pressure gas, also can be guaranteed that the required working pressure of gas equipment keeps the controlling device of steady state from start to finish, therefore be generally mounted between air feed equipment and gas equipment.Existing decompressor adopts diaphragm to reset conventionally, move and make the suction port of decompressor open or close by diaphragm, to reach the effect of voltage stabilizing, but, its defect is: first, when above-mentioned decompressor is applied to low temperature environment lower time, diaphragm easily causes hydraulic performance decline because of low temperature effect, and then sensitivity is lower while causing moving; The second, the working life of diaphragm is shorter, when use change more frequent, cause user cost higher; The 3rd, owing to adopting diaphragm to reset, the area of diaphragm is larger, and its voltage regulation result is better, therefore make the volume of existing decompressor larger, inconvenience is installed when use.
Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple and reasonable, stable performance, sensitivity is higher, the life-span is long, user cost is lower, small volume, high sensitivity decompressor easy for installation.
For achieving the above object, the utility model is by the following technical solutions:
A kind of high sensitivity decompressor described in the utility model, the bottom that comprises valve body, is connected with valve body, in described valve body, be provided with valve pocket, valve body is provided with the suction port and the air outlet that are communicated with valve pocket respectively, removable being provided with and the piston of suction port corresponding matching in described valve pocket, between described piston, valve body and bottom, sealing forms damping cavity, in described piston, be provided with decompression runner, described decompression runner one end is communicated with described valve pocket, the other end of decompression runner is communicated with described damping cavity, between described piston and valve body, is provided with pressure-stabilizing spring.
Further, described suction port bottom moulding is provided with valve nozzle, and the top of described piston is provided with the caulking gum corresponding with valve nozzle.
Further, in described piston head outer wall and bottom outer wall, be all embedded with " V " V-shaped ring.
Further, described valve body is provided with the relief opening corresponding with piston.
Further, described valve body bottom is located in described bottom welding.
The beneficial effects of the utility model are: by the removable piston coordinating with suction port that is provided with in valve pocket, between piston, valve body and bottom, sealing forms damping cavity, in piston, be provided with the decompression runner being communicated with valve pocket and damping cavity respectively, between piston and valve body, be provided with pressure-stabilizing spring.The utility model makes suction port open or close by piston action, and when work, performance is more stable, and sensitivity is higher, and the life-span is longer, and user cost is lower, small volume, easy for installation.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure:
L, valve body; 2, bottom; 11, valve pocket; 3, suction port; 4, air outlet; 5, piston; 6, damping cavity; 51, decompression runner; 7, pressure-stabilizing spring; 31, valve nozzle; 52, caulking gum; 53, V-shaped ring; 12, relief opening.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of high sensitivity decompressor as shown in Figure l, comprise valve body l, the bottom 2 being connected with valve body l, in described valve body 1, be provided with valve pocket 11, valve body 1 is provided with the suction port 3 and the air outlet 4 that are communicated with valve pocket 11 respectively, interior removable being provided with and the piston 5 of suction port 3 corresponding matching of described valve pocket 11, described piston 5, between valve body l and bottom 2, sealing forms damping cavity 6, in described piston 5, be provided with decompression runner 5l, described decompression runner 5l one end is communicated with described valve pocket 11, the other end of decompression runner 51 is communicated with described damping cavity 6, between described piston 5 and valve body l, be provided with pressure-stabilizing spring 7.
When suction port 3 is opened, a gas part in valve pocket 11 is passed through air outlet 4 for gas equipment, another part flows in damping cavity 6 through decompression runner 5l, in the time that the gas pressure intensity in damping cavity 6 increases to certain value, piston 5 moves under the effect of gas pressure intensity and shutoff suction port 3, suction port 3 is closed, now the gas in damping cavity 6 passes back into air outlet 4 through decompression runner 51, in the time that the pressure in damping cavity 6 reduces, piston 5 moves down under the effect of pressure-stabilizing spring 7, suction port 3 reopens, thereby makes the utility model reach the effect of circulation voltage stabilizing.
Adopt piston 5 and pressure-stabilizing spring 7 interoperations to make suction port 3 opening and closing, sensitivity is higher, and performance is more stable, the utility model can be applied in various rugged environment, and piston 5 is longer than the diaphragm life-span, and user cost is lower, make the utility model small volume simultaneously, easy for installation.
Described suction port 3 bottom moulding are provided with valve nozzle 31; the top of described piston 5 is provided with the caulking gum corresponding with valve nozzle 3l 52; coordinate by valve nozzle 3l and caulking gum 52; both guaranteed that piston 5 plugging effects were better; caulking gum 52 has also played the effect of damping simultaneously; effectively protect piston 5, extended the working life of piston 5.
In described piston 5 top exterior walls and bottom outer wall, be all embedded with " V " V-shaped ring 53, both guaranteed sealing of the present utility model, " V " V-shaped ring 53, than other seal elements, also has resistance little simultaneously, the advantage that the life-span is long.
Described valve body 1 is provided with the relief opening corresponding with piston 5 12, in the time that piston 5 moves up and down, can discharge the gas of valve body l by relief opening 12, makes the inside and outside pressure of valve body 1 keep balance.Described bottom 2 is welded and is located at described valve body l bottom by argon arc welding, connects fasteningly, is difficult for dropping.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
