Abstract
The utility model discloses a novel piston-type float ball valve, which comprises a valve body and a float ball, wherein the float ball is provided with a connecting rod, and the connecting rod is fixedly connected with an adjusting member which can adjust the height of the connecting rod; one end of the valve body is provided with a water inlet, and the other end of the valve body is provided with a water outlet; the adjusting member is also fixedly connected with a driving lever, and the end part of the driving lever is an arc-shaped surface and extends into the water outlet; and a cavity of the valve body is provided with a valve core and a horn-shaped valve opening, wherein the valve core passes through a snap spring, a piston is connected to the head of the valve core, the side surface of the piston butts against the valve opening correspondingly, and the tail part of the valve core is hemispheric and is in contact with the arc-shaped surface of the end part of the driving lever. Due to the adoption of the structure, the novel piston-type float ball valve disclosed by the utility model has the advantages of simple structure, lower cost, suitability for various sizes of float balls and wider adaptability.
Description
Technical field
The utility model relates to water valve, particularly a kind of novel piston type float valve.
Background technique
Existing float valve generally only relies on the floating function of ball float, and water shutoff is realized in the water inlet that makes plug push against annular, on the one hand; The two is relative for the hydraulic pressure of the water generates of buoyancy and inflow valve body, and buoyancy has been fallen by partial offset, and on the other hand, plug contacts with the water inlet; Be only limited to the circle of water inlet nose end, surface of contact is less, and easy abrasion, and these all can cause the water sealing effect of plug not good enough; Leak easily, in addition, existing floating ball valve structure relative complex; Cost is higher, and volume is bigger, and these all have much room for improvement.
The model utility content
The technical problem that the utility model will solve provides a kind of novel piston type float valve, and not only valve control is respond well, and simple in structure, and cost is lower, and ball float volume size is all suitable, and adaptability is wider.
For solving the problems of the technologies described above, the technological scheme of the utility model is: a kind of novel piston type float valve is provided, comprises valve body and ball float; Ball float has connecting rod, and the adjusting element of its height of connecting rod and can regulate is fixedly connected, and an end of valve body is a water intake; The other end is a water outlet; Adjusting element also is fixedly connected with driving lever, and the driving lever end is an arc shaped surface, and stretches in the water outlet; Body cavity is provided with spool and flaring valve port, and spool passes jump ring, and the spool head is connected with piston, and the side of piston is corresponding with valve port to push against, and the spool afterbody is a hemisphere, and its arc shaped surface with the driving lever end contacts.
Aforesaid novel piston type float valve, piston end surface is with sealer.
Aforesaid novel piston type float valve, the spool outer wall is with Returnning spring.
Aforesaid novel piston type float valve, the sealer that piston end surface overlapped is a silica gel.
Above-mentioned novel piston type float valve, owing to rely on piston to realize water shutoff, piston is contact face-to-face with contacting of valve port, area of contact is bigger; Not easy to wear, and take advantage of a situation by the hydraulic pressure of the water generates that flows into valve body and to push against piston, hydraulic pressure does not receive any counteracting, thereby; Water sealing effect is good, and, simple in structure; Cost is lower, and ball float volume size is all suitable, can be adaptable across small-sized household or large scale industry water supply equipment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Longitudinal section when Fig. 1 closes for said model utility piston;
Fig. 2 is the said model utility piston longitudinal section when opening.
Embodiment
Referring to Fig. 1, a kind of novel piston type float valve is provided, comprise valve body 1 and ball float 2; Ball float 2 has connecting rod 3, and the adjusting element 4 of its height of connecting rod 3 and can regulate is fixedly connected, and an end of valve body 1 is a water intake 5; The other end is a water outlet 6; Adjusting element 4 also is fixedly connected with driving lever 7, and driving lever 7 ends are arc shaped surface, and stretches in the water outlet 6; Valve body 1 inner chamber is provided with spool 8 and flaring valve port 9, and spool 8 passes jump ring 10, and spool 8 heads are connected with piston 11, the side of piston 11 and valve port 9 corresponding pushing against, and spool 8 afterbodys are hemisphere, its arc shaped surface with driving lever 7 ends contacts.Piston 11 end faces are with sealer, can be silica gel specifically, and not only sealing effect is better, and can reach the hygienic requirements of food production.Spool 8 outer walls are with Returnning spring 12.
During use, referring to Fig. 1, piston 11 is closed, and promptly piston 11 pushes against valve port 9, and float valve is in and stops the water supply state, and this moment, ball float 2 floated, connecting rod 3 levels, and the hemisphere of spool 8 afterbodys contacts with the arc shaped surface middle part of driving lever 7 ends.Referring to Fig. 2, when ball float 2 drawdown of living in, ball float 2 descends thereupon; Connecting rod 3 and then drive driving lever 7 ends upwarp; The arc shaped surface of driving lever 7 ends promptly produces thrusting action to spool 8 afterbodys, spool 8 reaches, thus piston 11 is backed down forward; Water liquid can flow out water supply start through water outlet 6 from valve port 9.In the water supply process, ball float 2 rises gradually, and driving lever 7 ends fall gradually; Spool 8 resets gradually, and piston 11 is also resetted by the acting in conjunction of hydraulic pressure and Returnning spring 12 gradually, when water level rises to designated water level; Piston 11 pushes against valve port 9 again, and float valve stops to supply water.Above-mentioned working procedure is capable of circulation back and forth.
Because the pressure that ball float 2 produces only is used to push piston 11 open, rather than pushes against piston 11 and supply water stopping, thereby; Required buoyancy is not very big; That is to say that the volume of ball float 2 not only can be bigger, can also do lessly; The utlity model has extensive applicability thereby make, can generally be applicable to small-sized household or large scale industry water supply equipment.
The foregoing description is the preferred embodiment of the utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to the protection category of the utility model.
