Abstract
The utility model discloses a float valve of rotary valve core, belongs to the technical field of the structure of the float valve, and aims to overcome the defect of easy abrasion caused by the frequent long-distance and oppositely axial movement between cylindrical valve cores and valve ports of the existing float valve. The float valve comprises a valve seat, a floating ball, a connecting rod and a water inlet, wherein a core sleeve is closely arranged inside the valve seat in a non-rotatable mode, a through hole is arranged on the side wall aligning to a water inlet channel on the valve seat on a core sleeve, a valve core is closely and rotatablely arranged in the core sleeve, a water outlet is arranged at one end of the valve core, the connecting rod is arranged at the other end of the valve core, and a water inlet through hole is arranged on the side wall of the valve core.
Description
Technical field
The utility model relates to a kind of structure technology of float valve, particularly relates to a kind of float valve of rotary spool.
Background technique
Float valve is to utilize the buoyancy of ball float on liquid level, through the keying of spool in the connecting rod control valve body and valve base chamber, carries out fluid infusion or stops fluid infusion, makes liquid level remain on the height of a setting.Because float valve is high to the control accuracy of liquid level, water level does not receive the interference of hydraulic pressure height, so, not only on the high low cistern of the water tower of supply and drain water system, pond, cleaners and polishes, obtain general application; Simultaneously, in industries such as chemical industry, oil, rock gas, metallurgy, freezer refrigerations, also be an important components in the related system.Present float valve, its spool and valve opening that plays the keying effect is cylindrical, though relevant technical specification all requires its linking mechanism should guarantee the mobility of each contact, valve core should be light and steady moving of valve opening, and the jam phenomenon must not be arranged; Simultaneously, to the spool of the float valve that uses in various different occasions and valve seat etc. with material and whether answer quenching with Subsequent tempering, the hardness of each part of matching, or the like detailed regulation and requirement all arranged.But; Because float valve in use, its liquid level of controlling is often fluctuation, and it is frequent to cause it to open and close; Again the moving to axial of carrying out longer distance between spool and the valve opening; Therefore be easy to occur that to cause valve opening degree of finish not enough because of serious wear, or cause the softer side of material and be phenomenons such as ellipse or taper shape, make float valve malfunctioning at last; Cause the system that controls by float valve to break down and cause damage, when even more serious, also can therefore have an accident.
Summary of the invention
The purpose of the utility model provides a kind of float valve of rotary spool, overcomes between cylindrical spool and the valve opening of existing float valve frequently to carry out moving to axial of longer distance and the deficiency of easy abrasion.
The utility model is achieved through following technical proposals.
The utility model comprises valve seat, ball float, connecting rod and water intake; Core retainer plate closely is housed in said valve seat un-rotatably; The intake tunnel that the sidewall of said core retainer plate is aimed on the said valve seat is provided with through hole; Spool closely and rotationally is housed in the said core retainer plate, and an end of said spool is provided with water outlet, the other end is equipped with said connecting rod and on its sidewall, is provided with into water through hole.Among the design; Should adopt stationary fit between said core retainer plate and the valve seat; And adopt movingly between said spool and the said core retainer plate; Therefore promptly let said spool in said core retainer plate, rotate neatly, but can not let liquid carry out seepage flow, in degree of finish, higher requirement is arranged on to the quenching with Subsequent tempering of material and tolerance fit through the gap between their inside and outside wall.The keying of float valve is to be realized by the rotation of said spool in core retainer plate; Smooth and suitable Hardness Match between said spool and the core retainer plate makes mutual frictional force of rotating the surface very little, so open and close very flexibly and laborsaving, wearing and tearing can reduce widely.
For the frictional force between said spool and the core retainer plate is further reduced, ball bearing is equipped with at the two ends between said spool and the said core retainer plate.Like this, through said connecting rod transmission, from ball float sink-float or rock the radial component that is produced and also bear by said ball bearing for said spool.
Against existing technologies, the beneficial effect of the utility model is:
Reduce the wearing and tearing of spool and core retainer plate greatly, prolonged the working life of float valve; It is more accurate to make float valve exchange amount of restriction; Diminish owing to open and close required strength, can suitably reduce the volume of ball float or shorten connecting rod, help saving material or dwindle the shared space of float valve.
Description of drawings
Fig. 1 is the structural representation of the utility model, and Fig. 2 is that the A of Fig. 1 is to view.Among the figure: 1, valve seat, 2, ball float, 3, connecting rod, 4, water intake, 5, core retainer plate, 6, spool, 7, water outlet, 8, ball bearing.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
In the utility model, the manufacturing and the assembling of parts such as valve seat 1, ball float 2, connecting rod 3 are existing technology; Key is the cooperation between core retainer plate 5 and the spool 6, should accomplish that spool 6 can rotate neatly in core retainer plate 5, but must not have the gap that can cause seepage to exist, and again can be durable in use; So indexs such as the fit tolerance between them, degree of finish, hardness, coaxality all should strictly be carried out relevant machine-building and assembling standard.The apolegamy of ball bearing 8 also must have higher accuracy standard, otherwise can influence the coaxality between spool 6 and the core retainer plate 5.Embodiment as shown in Figure 1; Be in closed condition, along with the decline of liquid level, ball float 2 falls; Drive spool 6 rotation counterclockwise through connecting rod 3; When the through hole of spool 6 sidewalls when through hole on core retainer plate 5 sidewalls begins to overlap, the intersection that the flow that then flows into from water intake 4 just can be through above-mentioned through hole is by water outlet 7 outflows, float valve is opening state; When above-mentioned through hole overlapped fully, it is maximum that open degree reaches.When the liquid level rising, ball float will rise with liquid level, drives spools 6 through connecting rod 3 and turns clockwise, and the through hole contact ratio of spool 6, core retainer plate 5 sidewalls is diminished until disappearance gradually, and float valve just is in closed condition.As for the control of the lowest order of ball float 2 with its to the adjustable structure of liquid level, those skilled in the art person is accomplished easily, so this paper will not relate to.
Claims (2)
1. the float valve of a rotary spool; Comprise valve seat, ball float, connecting rod and water intake; It is characterized in that core retainer plate closely is housed un-rotatably, and the intake tunnel that the sidewall of said core retainer plate is aimed on the said valve seat is provided with through hole in said valve seat; Spool closely and rotationally is housed in the said core retainer plate, and an end of said spool is provided with water outlet, the other end is equipped with said connecting rod and on its sidewall, is provided with into water through hole.
