Description
Technical field
The utility model belongs to valve technology field, relates to a kind of combined valve.
Background technique
Reduction valve is the parts by regulating on reduction valve, regulates loine pressure, and relies on the energy of medium itself, make the valve that outlet pressure keeps stable automatically.From hydromechanical viewpoint, reduction valve is the throttle element that a local resistance can change, and namely by changing orifice size, the kinetic energy of flow velocity and fluid being changed, causes the different pressure losses, thus reach the object of decompression.Then rely on the adjustment of control and regulation system, the fluctuation of downstream pressure and spring force are balanced each other, makes downstream pressure keep constant in certain margin of error.
Safety valve is used for having run important protective action to personal safety and equipment.Safety valve is generally in closed condition, only has when the pressure medium in equipment or pipeline increases to over specified value, and safety valve is opened, and outside system, discharge medium prevents pressure medium in pipeline or equipment from exceeding setting numerical value.
In some pipe-line systems, need to use reduction valve and safety valve simultaneously, such as, Chinese invention patent application (application publication number: CN 103867898 A, Shen Qing Publication day: 2014.06.18) disclose a kind of nitrogen decompression cabinet, comprise decompression cabinet, suction port, air outlet, high pressure hose, safety valve A, one-level pressure relief valve, second depressurized valve, one-level bypass valve, safety valve B, second depressurized valve pressure gauge, manual ball valve A, manual ball valve B, manual ball valve C, manual ball valve D, connection mouth A, connection mouth B, one-level bypass line is had additional in decompression casing, one-level bypass valve and pressure reducing orifice A is had additional on one-level bypass line side, secondary bypass line is had additional in decompression casing, secondary bypass valve and pressure reducing orifice B is had additional on secondary bypass line side.
In this pipe-line system, reduction valve and the separate setting of safety valve, make taking up room of pipe-line system large, use inconvenience, its installation also comparatively bothers.In addition, the component arranged separately needed for reduction valve and safety valve are more, and also make the less stable of this pipe-line system, rate of fault is higher.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the combined valve that a kind of structure is comparatively stable.
The purpose of this utility model realizes by following technical proposal:
A kind of combined valve, it is characterized in that, comprise the valve body one of integral structure, described valve body one have water intake and water outlet, be provided with reduction valve and nonreturn valve core between described water intake and water outlet, valve body and the valve body one of described reduction valve are integral type structure, and described reduction valve is arranged between water intake and nonreturn valve core, be provided with safety valve between described nonreturn valve core and water outlet, the inner chamber of described valve body one is connected with reduction valve, safety valve.
In this combined valve, because valve body one is integral type structure, the component of water circuit system are less, and it is convenient for production, and also improve the stability of combined valve structure.In addition, valve body one structure of integral type, also makes the structure of this combined valve comparatively compact, takes up room little during use.Wherein the concrete structure of reduction valve can adopt China Patent No. be 201220392148.0 structure.Wherein, safety valve can adopt China Patent No. be 201320766682.8 structure, the lower end of the valve body of this safety valve is fixed on the valve body one of this combined valve.Wherein, nonreturn valve core can adopt China Patent No. to be the structure of safety check in 201020242515.X.
In above-mentioned combined valve, the entirety of described nonreturn valve core is positioned at valve body one inside.Inner owing to whole nonreturn valve core to be all arranged on valve body one, avoiding through hole that to offer on valve body one for installing nonreturn valve core so that valve body one leaks, making the structure of combined valve entirety comparatively stable.
In above-mentioned combined valve, described valve body one is provided with the interface for connecting other valve or pipeline.When joint does not use, joint is blocked by available plug.
In above-mentioned combined valve, the quantity of described interface is two and lays respectively at the both sides of nonreturn valve core.
In above-mentioned combined valve, described valve body one has annular groove one, described safety valve has the annular groove two corresponding with annular groove one, be provided with a jump ring between described valve body one and safety valve and described jump ring is positioned at annular groove one and annular groove two.Sidepiece due to safety valve has the joint for connecting pipeline, and joint has certain length, by jump ring, safety valve and valve body one are linked together, instead of safety valve is threaded on valve body one, avoid the rotation of safety valve in installation process, make the structure of this combined valve more compact.
Compared with prior art, in this combined valve, valve body one is integral type structure, and its amount of parts is less, makes its structure comparatively stable.
