Description
Technical field:
The present invention relates to a kind of valve, specifically is a kind of vacuum breaker.
Background technique:
Vacuum breaker is mainly used in potable water system, can eliminate the vacuum in the delivery (pipe) line automatically, prevents that effectively the polluted water siphon from refluxing.Vacuum breaker comprises valve body, cover cap, bonnet, goes up seal ring, goes up sealing gasket, goes up dish, first spring, lower wall, lower seal pad, lower seal and valve seat.Said bonnet, go up seal ring, go up sealing gasket and go up dish and form outlet valve.Described valve seat, lower seal, lower seal pad and lower wall form safety check.Can be provided with one second spring between the last sealing gasket of the vacuum breaker of existing technology and the first limited ring upper surface; Purpose is to go up sealing gasket when receiving the pressure of the regulation that is near the mark; Last sealing gasket is against the part meeting projection on described second spring; Make to go up other parts of sealing gasket can not with the face seal of valve gap through hole end, just have gas and get into valve body and open outlet valve this moment.
There is following shortcoming in the vacuum breaker of above existing technology:
1,, just can't be installed on two perhaps parallel on same straight line water pipes because structure is angie type mostly, and promptly intake pipe and outlet pipe vertical distribution are concerned by like this mounting point.
2, because the control valve opening and closing are to cooperate with the valve gap through hole through sealing gasket, i.e. sealing between face and the face is out of shape and when smooth inadequately, can be reduced sealing effect at sealing gasket like this.
Summary of the invention
The technical problem that the present invention will solve is that a kind of vacuum breaker that can be installed on two perhaps parallel on same straight line water pipes, can guarantee sealing effect is provided.
Technological scheme of the present invention is, a kind of vacuum breaker with following structure is provided, and comprises valve body, valve gap; Said valve gap is located at the top of valve body; And be provided with connecting valve intracoelomic cavity and extraneous suction port, said valve body is provided with intake pipe and outlet pipe, and said valve body is provided with the first passage that is used to water into, be used for the second channel of water outlet and be used for the third channel of air inlet; Said first passage inboard is provided with lower valve base, is provided with upper valve base in the said valve gap; The axis of the intake pipe of said valve body is located along the same line with the axis of outlet pipe or is parallel, and the position between upper valve base and lower valve base in the said body cavity is provided with the valve ball that control valve body is opened or closed.
The said valve ball outside also is provided with ring support.
The wall of said ring support is provided with filter screen.
Said valve ball outer surface also is coated with the skin of being processed by teflon, and said outer field external diameter is less than the internal diameter of lower valve base and upper valve base.
After adopting said structure, the present invention compared with prior art has the following advantages:
1, owing to state axis and the axis of outlet pipe of the intake pipe of valve body and be located along the same line, can be installed in like this between two parallel or parallel water pipes.
2, open or close owing to adopting valve ball to distinguish, saved original upper-lower seal pad, make simple in structure as valve; And the sealing of the first passage of valve ball and valve body and second channel, be being sealed and matched of sphere and through hole, good sealing effect.
As improvement, the said valve ball outside also is provided with ring support, can prevent that valve ball from departing from, and guarantees effective sealing of valve ball and valve body, valve gap.
As further improvement, the wall of said ring support is provided with filter screen, the impurity in can filtered water.
As improvement; Said valve ball outer surface also is coated with the skin of being processed by teflon; Said outer field external diameter is less than the through hole internal diameter of lower valve base and upper valve base; It is low to make valve ball have a good antiacid alkali resistant, anti-various organic solvents, white high temperature, friction factor like this, can better be close to lower valve base and upper valve base and seal.

Embodiment
Below in conjunction with accompanying drawing vacuum breaker of the present invention is described further.
Like Fig. 1, shown in Figure 2, vacuum breaker of the present invention comprises valve body 1, valve gap 2; Said valve gap 2 is located at the top of valve body 1, and is provided with the suction port 2.1 that is communicated with valve body 1 inner chamber and the external world, and said valve body 1 is provided with seal ring with the joint of valve gap 2; Said valve body 1 is provided with intake pipe 1.1 and outlet pipe 1.2; Said valve body 1 is provided with the first passage 1.3 that is used to water into, be used for the second channel 1.4 of water outlet and be used for the third channel 1.5 of air inlet, and said first passage 1.3 inboards are provided with lower valve base 3, the sealing gasket of this lower valve base 3 for being processed by rubber material; Be provided with upper valve base 4 in the said third channel 1.4, this upper valve base 4 processes for one with valve gap 2; The axis of the intake pipe 1.1 of said valve body 1 is located along the same line with the axis of outlet pipe 1.2 or is parallel; The axis of the intake pipe 1.1 of the valve body 1 of present embodiment and the axis of outlet pipe 1.2 are located along the same line; The position between upper valve base 4 and lower valve base 3 in said valve body 1 inner chamber is provided with the valve ball 5 that control valve body is opened or closed; This valve ball 5 can offset with lower valve base 3 or upper valve base 4 respectively, and sealing is sealed the through hole of upper valve base 4 when offseting with lower valve base 3; Sealing is sealed the through hole of lower valve base 3 when offseting with upper valve base 4.
Said valve ball 5 outsides also are provided with ring support 6, and the wall of said ring support 6 is provided with filter screen 7.This ring support 6 is the cylindrical of hollow, and the upper and lower end face is opening.
Said valve ball 5 outer surfaces also are coated with the skin of being processed by teflon 5.1, and said outer 5.1 external diameter is less than the through hole internal diameter of lower valve base 3 and upper valve base 4.Behind these valve ball 5 parcels outer 5.1, can be free up and down in ring support 6.
Vacuum breaker working principle of the present invention: when the water intake intake pressure just often, under the effect of hydraulic pressure, overcome the gravity of valve ball 5 self; Valve ball 5 breaks away from lower valve base 3; Float to valve gap 2 and combine closely, and with the sealing that offsets of the upper valve base 4 of valve gap 2, at this moment; Gas-entered passageway cuts off, and current are normal in the pipeline; When water intake does not have the pressure of pressure ratio water intake of water or water outlet high, under the effect of valve ball 5 self gravitations, the sealing that offsets of valve ball 5 and lower valve base 3; Prevent aqueous reflux; Valve gap 2 breaks away from valve ball 5, and suction port 2.1 has air to get into, and prevents that the water siphon that exports from refluxing; The one, anti-sealing causes secondary pollution, and the 2nd, prevent water consumption device or water pump are caused impact of water hammer.
Above embodiment is merely preferable embodiment of the present invention, the present invention also allows other and changes, all within the scope of the claims, all in the protection domain of claim of the present invention.
