For solving the problems of the technologies described above, the flow-limiting valve of the plumbing for building equipment robot control system(RCS) of the utility model band muting function, comprising: housing, and described housing is hollow structure; Fitting seat, described fitting seat is connected to the tail end of described housing by connecting rod; Wherein said fitting seat comprises: base, and described base is connected to the tail end of described housing by connecting rod; Sleeve pipe, one end of described sleeve pipe is connected with described base, and other one end of described sleeve pipe is that opening is arranged; Current limliting bar, one end of described current limliting bar is inserted the opening of described sleeve pipe, is stretched into described cannula cavity; Spring, described spring is arranged between described base and described current limliting bar, is positioned at described cannula cavity; Current limliting block, described current limliting block is connected with the other end of described current limliting bar; Fixed block, described fixed block is arranged in described inner walls; Flow-limiting plate, flow-limiting plate described in polylith is connected with the outer wall of described inner walls and described sleeve pipe respectively; Noise reduction piece, described noise reduction piece is arranged on the tail end of described housing.
Also be provided with at the tail end of described current limliting bar and help to shoulder heavy thing.
The side of described current limliting block is taper.
Described noise reduction piece comprises: noise reduction piece body; Metering hole, described metering hole is arranged on described noise reduction piece body; Groove, described groove is arranged on described noise reduction piece body, and one end of described groove extends to the edge of described constrictor body, and the other end of described groove communicates with described metering hole.
Described groove is two, and two described grooves are for being symmetrical arranged.The groove width of described groove is less than the diameter of described metering hole.
The current limliting block of the flow-limiting valve of the plumbing for building equipment robot control system(RCS) of the utility model band muting function is fitted with fixed block in an initial condition, when there being current to carry out in housing, current can impact current limliting block, current limliting block is moved backward, gap is opened between current limliting block and fixed block, form flow channel, simultaneously under the guiding of current limliting block surface conical surface, current enter in valve body along flow channel.Current limliting bar is connected with the base on fitting seat by spring, under the action of the spring, the distance of current limliting block movement backward in sleeve pipe has the limit, that is the maximum flow of current is conditional, when current limliting block moves backward to the position of the limit, the flow of the current passed through also will reach peak value.Meanwhile, the helping to shoulder heavy thing of tail end of current limliting bar can prevent current limliting bar from coming off.In addition, the outside of sleeve pipe and the inwall of housing are also crisscross arranged flow-limiting plate, between flow-limiting plate, interval is arranged, form bent road completely, can make on the one hand through the speed of current reduce, reduced velocity flow, to reduce because of the too fast impact to water pipe of current, in addition on the one hand, in the very large situation of moment current, bent road can store a certain amount of water by its longer water channel, plays the effect of buffering.
Simultaneously, noise reduction piece body offers the groove communicated with metering hole, it can upset the current by metering hole, namely feed water flow is through noise reduction piece, arranging of groove can form another water route, can produce mutual interference between itself and the water route of metering hole, and turbulent flow occurs, the current producing noise deflect, and thus can reach the noise reduced because the sudden change of metering hole bore produces.
