Abstract

The utility model belongs to a diaphragm ball float valve by using the technology of ball floats and control valves, composed of a valve casing, valve holes and a ball float which is placed in the valve casing. The ball float can change the distance from the ball float to the valve holes according to the liquid level formed by the liquid which enters the valve casing, and can conduct the control to the liquid level and gas blocking. The utility model is configured as a diplopore closed type with a single ball and a single chamber and can be used individually or in the way of multistage concatenation. The utility model solves the problems of anti plugging, isolation of osmyl and resistance of reverse of the drainage of the buildings by using the simplest structure, and can also be used for the self control of the liquid level of feeding water in a closed type water tank, etc.

Description

Diaphragm floating ball valve

The utility model relates to a kind of autocontrol valve that utilizes ball float, particularly a kind of anti-blocking in building industry draining field, every obstruct float valve smelly, counterseal, it also can be applied to the last water automatic control of liquid of closed water tank.

For the indoor drainage and the drainage pipeline of building, the water seal of generally adopting bowl bell-type floor drain and S shape water pipe to form now reaches the effect that intercepts the sewerage foul smell.This class water seal part has been used for many years and has seldom been made an exception in existing building is installed.But this water seal deficiency is: once, do not intercept foul smell when not forming water seal, this is often to occur in floor drain is used, because the water seal annular groove water amount of floor drain seldom and the water seal that forms very shallow, do not have on ground regular draining by the time water in the annular groove will soon evaporate, lose the water seal effect; Two, water seal can't resolve the contrary problem of overflowing of sewage of sewerage, and this is to live in " disaster " that the people of building bottom worry most.Though have the technology that some are applied to ball float draining control in recent years, dive the ball float reverse-stop type from control draining valve as the Chinese utility model patent 91210699.9 of authorizing March in this year, though it has solved the contrary problem of overflowing of sewage, but it does not still break away from the dependence to water seal, in case water seal loses, still can't intercept the foul smell of sewerage.This in addition product structure is complicated, and can only can not be applied among the drainage pipeline as floor drain.

The purpose of this utility model provides and need not water seal, can intercept the sewerage foul smell, can prevent from again that sewage is contrary to overflow; Can be used for land drainage as floor drain, can be used for drainage pipe as sewer spare again; Can remedy product as the smelly anti-reverse practicality of resistance of existing floor drain, urinal and drainage pipeline, again can be as a kind of the most simple and reliable obstruct float valve of Updated product in the field of building industry draining from now on.Simultaneously, it can also be used in the last water automatic control of liquid of closed water tank or the aspects such as automatic vent hole of water heating type radiator.

The utility model is a principle of utilizing ball float to fluctuate greater than the liquid level of its liquid with proportion, with reference to the obstruct float valve of one of the action effect design of the one-way valve special construction of being made up of valve casing, valve opening and spool.This float valve is single ball single chamber diplopore enclosed, and its structure is: valve body is made up of valve casing and valve opening, and valve casing is the spheroid or the spheroid of a hollow; Valve body two ends up and down respectively has a hollow circular cylinder identical, that be symmetrically distributed as valve opening; Spool be a diameter greater than the valve opening internal diameter less than valve casing maximum cross section internal diameter, can be in valve casing free-moving bead, the proportion of the liquid that the proportion of bead is controlled less than this valve; Last valve opening outer end has one to go up double-edged fine-toothed comb, and there is a following double-edged fine-toothed comb following valve opening outer end or the inner.Two or more these valve lontitudinal series one be can be become in addition, a two-stage or multistage obstruct float valve become.When liquid entered, the ball float that plays the spool effect in the obstruct float valve just fluctuated with the liquid levels that enters valve casing, thereby reached the effect of self regulating valve hole aperture.The utility model can also be applied to the last water automatic control of liquid of closed water tank, as is used to be interrupted the automatic control of liquid of closed water tank of water supply or automatic vent hole of water heating type radiator etc.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is that single ball single chamber diplopore enclosed intercepts float valve

Fig. 2 is that down open type list ball single chamber diplopore tandem obstruct float valve is used for water automatic control of liquid level schematic representation

As shown in Figure 1, last double-edged fine-toothed comb 1 stops that the bulk foreign material enter valve body and play anti-blocking effect, and when not having few and the not enough so that ball float 4 of liquid or amount of liquid to float in the valve casing 3, ball float 4 drops on the valve opening 5 by gravity, has intercepted the interchange of gas.When liquid flowed into valve body from top to bottom, ball float 4 levitatings had been opened valve opening 5, make the flow of liquid mistake, continued to intercept the interchange of gas simultaneously.As liquid is reverse when entering valve body, ball float 4 rises until blocking valve opening 2 with liquid level, and reverse pressure is big more, and valve opening 2 is closed tightly more, has stoped emerging of liquid.This single ball single chamber diplopore enclosed intercept float valve be applied to sewerage or floor drain can play anti-blocking, every effect smelly, counterseal.Valve casing 3 inner wall smooths do not have the dead angle, available metal or plastics manufacturing.Valve opening 2,5 and ball float 4 contact segments are certain taper, ball float 4 any surface finish and certain elasticity, available plastics floating material or rubber material manufacturing are arranged.As shown in phantom in Figure 1, this product also has a kind of down open type, and double-edged fine-toothed comb 6 is increased to down the upper end of valve opening 5 under being about to, and descends valve opening 5 just can not be closed fully by ball float 4 like this.This down open type intercepts the automatic control of liquid that float valve is mainly used in closed water tank.

Fig. 2 intercepts the schematic representation that float valve is applied to the water automatic control of liquid level for down open type list ball single chamber diplopore tandem.Inlet valve 1 connects running water pipe and closed water tank 2 among the figure, and valve 1 is a hand sluice valve, just often is in normally open.Outlet valve 3 is a hand sluice valve, needs and switch with the user.Down open type list ball single chamber diplopore tandem intercepts float valve 5 and links to each other with the top of water tank 2 by its preceding valve 4, and valve 4 is a hand sluice valve, just often is in normally open.When running water system supplied water, high water tank rose gas is discharged through valve 4, valve 5, and when gas drains liquid level when arriving valve 5, the next stage of valve 5 is closed, and reaches case internal pressure and running water pipe internal pressure balance always.It is to increase safety factor that valve 5 adopts the purpose of plural serial stage, just in case malfunctioning the leaking of next stage also has upper level to check on.When running water system stops to supply water and user's open valve 3 when using in the water tanks water, along with liquid level decline ambient air by down open type list ball single chamber diplopore tandem intercept float valve 5, valve 4 enters water tank makes internal and external pressure balance, and unlikely generation negative pressure and put not water outlet.According to same technical conceive, this down open type list ball single chamber diplopore tandem intercepts the automatic vent hole use that float valve also can be used as the water heating type radiator.
