Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment Row elaborates.
As shown in Figures 1 to 9, the utility model discloses a kind of Check valve of current limiter structure, and it can be installed on water outlet dress In putting, the water inlet of gondola water faucet is such as installed on, or is installed in the water outlet of tap.
Described Check valve of current limiter structure includes the bonnet 1 and base 2 to cooperate, and the water inlet 11 of the bonnet 1 is set Limited fluid 12, current limiting sealing ring 13 is coordinated on the current limliting body 12, the external diameter of the current limliting sealing ring 13 is less than water inlet 11 internal diameter, between bonnet 1 and base 2 activity be combined with nonreturn valve core 3, spring 4 is provided between nonreturn valve core 3 and base 2;Just When often crossing water, nonreturn valve core 3 and spring 4 be pressurized it is positive it is mobile open water route, the current limliting sealing ring 13 on current limliting body 12 is pressurized meeting The discharge area of generation transverse deformation and then change water inlet 11 reaches the purpose of current limliting;When being more than water inlet end in water outlet end pressure During pressure, that is, when backflow phenomenon occurs, the reverse movement under the effect of the reset force of spring 4 of nonreturn valve core 3 can close water route, prevent Water side current are back to water inlet end.
Coordinate Fig. 1, specifically, the bonnet 1 is a column sleeve, upper end is water inlet 11, and lower end is with base 2 with synthesis one Body, the water inlet 11 connect the current limliting body 12 by some connecting bars 14, and the current limliting body 12 includes the He of a body 121 Some limit ribs 122 on body 121, the current limliting sealing is combined between the body 121 and limit ribs 122 Circle 13, wherein described limit ribs 122 can be from the outward-dipping arrangement in the centre of body 121 so that limit ribs 122 are presented A kind of petal-shaped of expansion, so that the maximum external profile diameter of the limit ribs 122 is more than the internal diameter of current limliting sealing ring 13 So that current limliting sealing ring 13 can be nested on current limliting body 12, prevent current limliting sealing ring 13 from being come off from current limliting body 12.In current limliting The inwall of bonnet 1 of the lower section of body 12 is inwards formed with block face 15 to coordinate nonreturn valve core 3 to realize the opening and closing in water route.It is described The lateral wall of bonnet 1 can form groove 16 with fitted seal circle 17 and form sealing with discharging device and coordinate.
The nonreturn valve core 3 includes sealing piece 31 and coordinates the valve rod 32 in the lower surface of sealing piece 31;The block face 15 Minimum inner edge diameter is less than the external profile diameter of sealing piece 31, and the nonreturn valve core 3 is located between block face 15 and base 2;It is described to stop Water piece 31 is upwardly formed a necking down 311 for being combined with non-return sealing ring 33, formed in necking down outwardly confined planes 312 with Limit non-return sealing ring 33;For ensure sealing piece 31 can against block face 15 and cause non-return sealing ring 33 be in close contact with block face 15 Form sealing to coordinate, the external profile diameter of the confined planes 312 is less than the external profile diameter of sealing piece 31.
The base 2 is also a column sleeve, and its top forms inner chamber and placed for nonreturn valve core, and lower end is formed with apopore Go out the water surface 21, go out the water surface 21 herein and coordinate provided with limited post 22 for the valve rod 32 of nonreturn valve core 3, to be realized to nonreturn valve core 3 The spacing function of guiding action.Wherein described limited post 22 can be hollow structure so that valve rod 32 places;Can also be described Valve rod 32 is hollow structure, and the limited post 22 is nested with for valve rod 32.Further, the periphery of the base 2 can be upwardly formed Several leads 23, the inner edge diameter that the lead 23 is formed are equal to the diameter of the side of sealing piece 31, are ensureing this practicality By lead 23 and limited post 22 it is also ensured that the direction that nonreturn valve core 1 moves will not be inclined while new discharge capacity Move, can guarantee that sealing piece 31 coordinates with the sealing of block face 15.
The lower end of the spring 4 acts against out the upper surface of the water surface 21, and upper end is held in the lower surface of sealing piece 31.
During actual use, the utility model is assembled in the water route of discharging device, as shown in Fig. 2 normally without water inlet when, bullet Spring 4 is to make the sealing piece 31 of nonreturn valve core 3 hold block face 15 in normal condition, and water route is blocked, and now the water in water route is It can not be flowed back from lower to upper part of the present utility model, realize the function of unidirectional counterflow-preventing.
Coordinate shown in Fig. 3, Fig. 5 and Fig. 7, when opening effluent switch and making discharging device normally intake, current are from bonnet 1 Water inlet 11 enters, and is acted on by hydraulic pressure, and nonreturn valve core 3 can be positive mobile downwards, and sealing piece 31 departs from block face 15, sealing piece 15 Water space was formed with the inwall of bottom 2 or the inwall of bonnet 1, realizes normal effluent functions, spring 4 now is in pressure Contracting energy accumulating state, water pressure hour is served as, i.e., for the moment, as shown in Figure 3 and Figure 4, hydraulic pressure is insufficient to allow current limliting sealing ring 13 to state Deformation, now the discharge area of water inlet 11 is maximum;When the water flow pressure further increases, i.e., state two when, such as Fig. 5 and figure Shown in 6, hydraulic pressure acts on the upper surface of current limliting sealing ring 13, and because of the elastic characteristic of current limliting sealing ring 13, current limliting is acted on by hydraulic pressure Transverse deformation can occur for sealing ring 13, so as to reduce the discharge area of its water inlet 11, so realize flow control function, reach The purpose of water saving.
Further, the water inlet 11 can include middle circular several relief areas for crossing aqua region and outer rim Domain so that when the water flow pressure continues increase, i.e. state three, as shown in Figure 7 and Figure 8, current limliting sealing ring 13 produce maximum distortion, Block the circular of water inlet 11 and cross aqua region, and gap regions normal can also cross water, ensure that forward direction of the present utility model crosses water Ability.The water hole 123 run through up and down can also be formed among the current limliting body 12, to ensure that forward direction of the present utility model crosses water Ability.
The utility model is when water side pressure occur and being more than water inlet end pressure, i.e. state four, as shown in figure 9, sealing piece When 31 insufficient pressures born against spring 4 to compress the elastic force resetted, spring 4 promotes sealing piece 31 to reset, and sealing piece 31 is anti- To moving up, sealing piece 31 coordinates with the sealing of block face 15, closes water route, can effectively prevent occurring backflow phenomenon in pipeline.
In summary, the utility model realizes current limliting work(by the transverse deformation of the current limliting sealing ring 13 on water inlet 11 Can, the inverse-stopping functions in water route are realized by the displacement of the nonreturn valve core 3 between bonnet 1 and base 2, it is simple in construction, can Using water wisely, and can ensure water safety guarantee.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art The appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
