Abstract
The utility model provides a control valve which comprises a valve body. The valve body comprises a fluid inlet, a valve cavity and a fluid outlet, wherein the fluid inlet, the valve cavity and the fluid outlet are communicated mutually. A valve core assembly capable of controlling open and close of the valve body is arranged in the valve cavity, and the valve core assembly comprises a valve core seat and a valve rod arranged by penetrating through the valve core seat. A valve cover is fixedly connected with the upper portion of the valve core seat, a cavity is formed between the valve cover and the valve core seat, a runner is arranged in the lower portion of the valve core seat, and the runner is arranged in the valve cavity and communicated with the fluid inlet and fluid outlet. A valve clack for sealing the runner is arranged at one end of the valve rod, and the other end of the valve rod is arranged by penetrating out of the valve cover, and an elastic element for reset of the valve rod in a vertical direction is arranged in the cavity. The control valve has the advantages that the sealing element is arranged between the valve clack and the runner, a traditional method of opening and closing the valve through an oblique wedge block is changed, an effect of sealing the valve is achieved by adopting a method of vertical motion of the valve clack. Such coordination is low in precision, the structure is simple and convenient, operation is simple and sealing effect is good.
Description
Technical field
The utility model relates to valve field, refers to especially a kind of modulating valve.
Background technique
To be flow control valve use the typical case of domain of control temperature thermostat valve, and its basic principle is: by control heat exchanger, air-conditioning unit or other with heat, cool equipment, once heat or heating agent inlet flow rate, to reach the control apparatus outlet temperature.When load changed, by changing the valve opening degree adjust flux, the impact that causes to eliminate fluctuation of load made temperature return to setting value.
Thermostat valve comprises radiator valve and modulating valve, wherein modulating valve plays important effect at the flow of automatically regulating modulating valve, and in the existing modulating valve, tapered wedges in all employings that control valve opens and closes, the quality of fit of such structure is high, causes manufacture cost higher, and installs loaded down with trivial details, sealing effect is bad, causes complex structure.
