Background technique
We know, valve is the important devices of break-make, rate of flow of fluid and change flow direction for controlling various fluid circuits.At present, the valve of the use in the field such as water conservancy, electric power, chemical industry, rock gas, heating adopts ball valve more.The structure of existing ball valve is: be provided with valve body, valve body is provided with liquid entering hole and liquid outlet, in valve body, be provided with the cylindrical liquid runner that is communicated with liquid entering hole and liquid outlet, in flow channel for liquids, be provided with spherical valve core free to rotate, that match with cylindrical liquid runner, spherical valve core middle part is provided with the via by its axis, spherical valve core one side is provided with handler, and handler extends to valve body outside through valve body.During use, control spherical valve core rotate in valve body by handler, via is relative with liquid entering hole and liquid outlet, when the two is communicated with, pipeline conducting, otherwise pipeline disconnects, and by controlling the angle of spherical valve core, flow that can regulating valve.This valve, the area of contact of spherical valve core and valve body is large, and unlatching moment is large, the easy fouling of valve interior wall, valve is easily stuck, high to water quality requirement.Ball valve is due to internal structure reason, and the via diameter at spherical valve core middle part is less than the diameter of liquid entering hole and liquid outlet, and flow coefficient is low, large to the liquid resistance of flowing through.Flow-rate adjustment in the inapplicable fluid pipeline of ball valve, is used it to control break-make, i.e. completely open and close conventionally.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of spool and valve body area of contact little, open moment little, use for a long time late gate to be difficult for stuck, can automated cleaning valve interior wall, the fluid regulating valve that flow control accuracy is high, regulation range is large
The technological scheme that the present invention solves above-mentioned the deficiencies in the prior art employing is:
A kind of fluid regulating valve, be provided with valve body, valve body is provided with liquid entering hole and liquid outlet, is provided with the cylindrical liquid runner that is communicated with liquid entering hole and liquid outlet in valve body, it is characterized in that being provided with in flow channel for liquids ogee spool free to rotate, that match with flow channel for liquids; Described ogee spool is: be provided with the fan-shaped upper backup pad and the lower supporting plate that match with flow channel for liquids, between upper backup pad and lower supporting plate, be provided with the arc valve central layer matching with flow channel for liquids, the fan-shaped circle centre position of upper backup pad upside is provided with handler, handler extends to valve body outside through valve body, the fan-shaped circle centre position of lower supporting plate downside is provided with locating stud, flow channel for liquids lower wall is provided with the slot matching with locating stud, slotting being embedded in slot that locating stud is free to rotate.
The valve body of flow channel for liquids described in the present invention below is provided with spool dismounting mouth, on spool dismounting mouth through the lower end cap that has been threaded.Slot is located at the central authorities of lower end cap, when spool stops up, opens lower end cap, can in the situation that not dismantling pipeline, take out spool cleaning, and after cleaning, spool is in place again, saves a large amount of maintenance manpowers, financial resources.
Arc spool described in the present invention and the flow channel for liquids sidewall contacting point of matching is the arc matching with flow channel for liquids, curvature is identical.Spool and liquid flow to close contact, and obturation effect is better.
The valve body at the liquid entering hole described in the present invention and liquid outlet place is provided with connecting base.Be convenient to install on pipeline.
The valve body at the liquid entering hole described in the present invention or liquid outlet place is provided with temperature transducer mounting hole, and temperature transducer mounting hole is provided with sealing cover.In the time of need to monitoring the interior fluid temperature of pipeline, mounting temperature sensor on temperature transducer mounting hole.It is simple, convenient to use.
The present invention, in the process of using, controls fan-shaped upper backup pad by handler and rotates in flow channel for liquids, drives ogee spool and lower supporting plate to rotate; The periphery of upper backup pad, lower supporting plate and arc valve central layer contacts with flow channel for liquids inwall completely, during by liquid entering hole or liquid outlet and flow channel for liquids blocking-up, valve closing, pipeline disconnects, after Spool rotating several angle, spool is separated with flow channel for liquids sidewall or rotate to flow channel for liquids one side liquid entering hole and liquid outlet conducting, valve open, pipeline conducting.Spool of the present invention and valve body area of contact are little, open moment little, use for a long time late gate to be difficult for stuck, during valve interior wall fouling, rotate one week spool, can automated cleaning valve interior wall, and low to water quality requirement, flow control accuracy is high, regulation range is large.
