Abstract
The utility model discloses a pressure reducing and stabilizing valve with pressure reducing holes which are connected in series with each other. The utility model is mainly composed of a valve body, a small hole seat ring, pressure reducing hole plates and a water outlet. The utility model is characterized in that a plurality of pressure reducing hole plates are connected in series with each other from the input end at the water outlet according to the hole size in an ascending order or a pressure reducing hole plate is connected in series with the small hole seat ring. The utility model has the advantages of simple structure, stable performance, large range of application and convenient use, and is proved by experiments to be completely capable of reaching the rated output pressure and flow of all grades in the operating range of the pressure reducing valve for fire fighting through configuring after the pressure is reduced through one small hole and is again reduced through another hole with the slightly larger size.
Description
Technical field:
The utility model relates to a kind of fire-fighting equipment, relates in particular to a kind of series connection decompression cellular type decompression venting valve.
Background technique:
Pressure reducing orifice is used in some local fire-fighting water decompression, and the pressure reducing orifice different pressures will be selected different specifications for use, selects difficulty for use.Some places fire-fighting decompression venting valve for this reason although these valve Applicable scope more greatly, generally be high pressure step-down output flow deficiency can the low pressure situation time, and structure is very complicated.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, has adopted a kind of series connection decompression cellular type decompression venting valve.
To achieve these goals, the technological scheme that its technical problem that solves the utility model adopts is, a kind of series connection decompression cellular type decompression venting valve, mainly form by valve body, aperture seat ring, pressure reducing orifice and water outlet, be characterized in: at water outlet several pressure reducing orifices are begun to be together in series by pore size is ascending from input end, or a pressure reducing orifice is connected with the aperture seat ring.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is simple in structure, be skillfully constructed, another aperture macropore decompression slightly of flowing through again after the decompression of aperture of evidence can reach fire-fighting reduction valve operating range 4kg～12kg/cm fully through configuration
2Specified delivery pressure of desired each grade and flow, and stable performance, Applicable scope big, select conveniently the tool promotional value for use.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Among the figure, a kind of series connection decompression cellular type decompression venting valve, the aperture seat ring 2 of pressure reducing orifice effect is equipped with in valve body 1 import, and water outlet 4 adds from input end and begins by the ascending pressure reducing orifice that is together in series 3 of pore size.Thus and thus, can reach fire-fighting reduction valve operating range 4kg～12kg/cm
2Specified delivery pressure of desired each grade and flow, and stable performance, Applicable scope big, select for use conveniently.
