Description
Technical field
The utility model relates to a kind of self-regulating device of constant current amount in the liquid communication pipe network that is exclusively used in, belong to flow regulator or valve class.
Background technique
In the prior art, the Flow-rate adjustment of fluid realizes by dedicated regulation valve, as shown in Figure 1, among Fig. 1, the liquid body pressure effect of spool, another side is the effect of spring by compression, spool moves along valve rod under fluid pressure and spring acting in conjunction, by the gap between the inverted cone liquid entering hole that changes spool and valve body, change the flow resistance of liquid, keep the constant relatively of flow.But the valve of this flow constant speed only is applicable to the fluid of big flow and flows, and its structure relative complex, and flow control accuracy is difficult to improve, and Applicable scope is little, and manufacture cost is also than higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of influenced by the fluid incoming pressure little and design, and can keep water flow constant automatically, the liquid constant current amount automatic control tegulatingdevice that constant-current control accuracy is high.It has a mobile cavity that is connected on pipeline or the valve, and the liquid outlet channel mouth in the cavity is provided with the flexible deformation component who has the runner hole.
The side that described flexible deformation component goes up near the liquid outlet channel mouth is provided with inside caveli.
Runner hole on the described flexible deformation component is arranged on axial intermediate portion.
The described cavity of the utility model is provided with the adjusting head, and the liquid outlet channel mouth in the middle of facing, and at a distance of nearer.
The utility model is provided with the adjusting head in flexible deformation component's centre, and stretches on the liquid outlet channel mouth of cavity taper.
Described flexible deformation component's centre is provided with the adjusting head, and with the liquid outlet channel mouth of cavity taper at a distance of nearer, the runner hole on the flexible deformation component is opened in the caveli that adjusting goes up in front.
The runner hole that is provided with in the described flexible deformation component is formed for the radial groove that the edge axial groove is communicated with on end face.
The utility model both can have been set up separately and specially be assigned in the fluid flow pipeline, also can be used in combination with configuration of valve such as solenoid valve or specialized designs, be characterized in that inlet pressure fluctuates in quite wide scope, can both keep rate of discharge and keep constant, its design principle is the continuity equation Q=AV according to flow.Flow-rate adjustment element in the liquid inlet pressure surge, cavity changes actual internal area A automatically, causes the variation of water flow velocity V with the compensatory pressure difference.Be that inlet pressure P is big more, the rate of flow of fluid V in the chamber is also big more, and then effectively actual internal area A becomes more little, and the AV product is maintained constant.Otherwise pressure P is little, and then flow velocity V variable quantity is little, and valid circulation area A variable quantity is also little, and the AV product is still kept constant, so, no matter becoming, inlet pressure diminishes greatly, this device all can keep the invariable of outlet port fluid flow.It compared with prior art has simple and reasonable for structurely, and volume is small and exquisite, control is convenient, low cost of manufacture can be widely used in various liquid quantitative discharging occasions, as large-scale refrigerator, the refrigerator water filling, washing machine inflow, the water heater current quantitatively discharge, and fish jar, pond are irritated automatically and are put, the bathtub scouring water are irritated automatically and are put, and soya-bean milk, milk, drinks be discharging or the like characteristics quantitatively.
