Description
Technical field
The utility model relates to opening and closing control valve in fluid delivery system, particularly relates to float controlled valve door device.
Background technique
The mechanical float ball autocontrol valve that container of the prior art and delivery line are arranged, its ball float will have enough volumes and the arm of force, the buoyancy produced is used for overcoming the gravity of self and the hydrodynamic pressure from transporting system pipeline, reach keying effect, the installation, maintenance of this structure all can be subject to spatial constraints, container must be made into big uncork form, and is unhygienicly not easily incubated; As the problem of the automatic control difficulty that solar water heater just exists, now mainly adopt electronic control water-supply apparatus, its shortcoming to be mainly arranged in water tank directly and testing circuit (probe) poor reliability of hot water contacts, easy to failure, rate of overhauling is high.
Model utility content
For the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of valve.
The basic conception of the utility model employing technological scheme is: comprise the outer tube body that there is interface one end, be provided with the valve body be made up of thick body and thin body and solid cylinder shape spool in this outer tube body the other end endoporus; Described thick body is fixed on the described outer tube body mouth of pipe, and on the cylndrical surface of described thin body and the cylndrical surface of described spool, cover has spiral spring, and make this valve body together with valve core housing, described spool is fixed with driving lever, this driving lever stretches out from the endoporus of described valve body.
The cylndrical surface of described thin body and the cylndrical surface of spool are respectively equipped with spiral spring fixed groove; Described spool external diameter is identical with described thin outer tube diameter; The end face contacted with described thin body of described spool installs sealing gasket; The endoporus of described thick body is horn-like; Be provided with positioning step in described outer tube body, between this positioning step and described spool, spring is set; The end face do not contacted with described thin body of described spool is extruded with step, and described spring housing is on this step; The end that described driving lever stretches out connects float.
The beneficial effects of the utility model are, what make use of float due to above-mentioned solution controls opening/shutting valve automatically from gravity and these two power of buoyancy, do not need to overcome the pressure from fluid in transporting system pipeline, the simple volume of structure is little, also directly can insert on container and use in existing interface endoporus, be convenient to install and arrange, little by condition restriction, can paperback or perpendicular sidepiece or the bottom being contained in container as required, maintenance and repair is very convenient, container does not need to be made into comparatively big uncork form, is beneficial to insulation, health, manufacture cheap etc.; This float-controlled valve also can be used on electric water heater, and its water tank just need not to be made into pressure-bearing, and cost can reduce, safer, hydraulic pressure is not enough anhydrous time water tank inside water also can release, do not have after-heat and abandon, saving power.
Accompanying drawing explanation
Structural representation when Fig. 1 is valve closing, structural representation when Fig. 2 is valve opening, Fig. 3 is that valve arranges float schematic diagram.
In figure: 1-interface; 2-outer tube body; 3-valve body; The body that 4-is thick; The body that 5-is thin; 6-spool; 7-spiral spring; 8-positioning step; 9-spring; 10-step; 11-sealing gasket; 12-driving lever; 13-float.
Embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, there is interface 1 outer tube body 2 one end, the valve body 3 be made up of thick body 4 and thin body 5 is provided with in the other end endoporus, thick body 4 is fixed on outer tube body 2 mouth of pipe, on the cylndrical surface of thin body 5 and the cylndrical surface of solid cylinder shape spool 6, cover has spiral spring 7, valve body 3 and spool 6 are nested together, spool 6 external diameter is identical with thin body 5 external diameter, and the cylndrical surface of thin body 5 and the cylndrical surface of spool 6 are respectively equipped with spiral spring fixed groove, spool 6 is fixed with driving lever 12, driving lever 12 stretches out from the endoporus of valve body 3, the end that driving lever 12 stretches out connects float 13.
During use, this valve level is arranged on container side, when the liquid level in container is low, under the Gravitative Loads of float 13, driving lever 12 is with movable valve plug 6 to reverse, and spiral spring 7 is out of shape, spool 6 and thin body interruption-forming gap, water is flowed into by gap, valve body 3 endoporus flows out, and valve is opening state; When the liquid level in container rises, buoyancy makes float 13 drive driving lever 12 to rise, spiral spring 7 restores to the original state, spool 6 and thin body 5 are fitted with one heart, water cannot enter from spool 6 and thin body 5 contacting point, at this moment valve is closed condition, it is pointed out that fluid pressure acts on spool 6 here and valve closing can be made more reliable.This valve can automatically be opened according to liquid level or close.Perpendicular dress also has same function, and this valve is vertically arranged on container bottom, and float 13 is horizontally placed on driving lever 12 end, and when liquid level is low, float 13 drives driving lever 12 to tilt, this valve opening; During liquid level height, driving lever 12 is upright, this valve closing.The height of liquid level is adjustable, is set by the length of driving lever 12.
More tight in order to make spool 6 contact with thin body 5, make valve closing more reliable, the end face that thin body 5 contacts with spool 6 is provided with sealing gasket 11.
Reverse stroke for expanding driving lever 12, add the gap that big valve core 6 is formed with thin body 5, increase the discharge value under valve opening state, the endoporus of thick body 4 is horn-like.
For improving reliability and the working stability of this valve further, positioning step 8 is provided with in outer tube body 2, positioning step 8 is provided with spring 9, the end of spring 9 withstands spool 6, the end face do not contacted with thin body 5 of spool 6 is extruded with step 10, spring 9 is enclosed within step 10, utilizes spring 9 to play support to spool 6 and corrective action.
This valve also to can be applicable to beyond water in other fluid delivery systems.
The utility model does not limit above-mentioned form, is such as stretched in spring 9 by driving lever 12, and can arrange the toggle mechanism of the various ways such as bracing wire, lever, push rod in outer tube body 2 relevant position perforate, can reach the control valve of other purposes; Float 13 is also not limited to be fixed as one with driving lever 12, also can adopt actively to be flexible coupling, bracing wire, the various ways such as pull bar.
