The anti-overflow vacuum shut-off valve comprises a valve body, a water inlet, a water outlet, an air inlet, a check valve component, an air inlet valve component and a valve bonnet and is characterized in that the check valve component comprises a lower disk, a sealing gasket and a spring, wherein a valve base of the check valve is arranged on the valve body, the spring is arranged between an upper disk and the lower disk, by virtue of the spring, the lower disk is kept downwards to be in contact with the valve base of the check valve so that the water inlet is kept closed, the air inlet valve component comprises the upper disk, a sealing gasket and the spring, a valve base of the air inlet valve is arranged on the valve bonnet, the spring is arranged between the upper disk and the valve bonnet, and by virtue of the spring, the upper disk is kept downwards to be separated from the valve base of the air inlet valve, so that the air inlet is kept in an air inlet state. According to the anti-overflow vacuum shut-off valve disclosed by the utility model, the spring is arranged between the upper disk and the lower disk, so that the condition that the sealing gasket of the upper disk is in contact with the valve base of the air inlet valve on the valve bonnet under the action of the spring force when the valve is switched on, and the indoor facility damage because water inside a pipeline splashes out from the air inlet is prevented.
Description
Technical field
The utility model relates to a kind of anti-spilled vacuum breaker.
Background technique
Owing to in the water supply system because reason such as cut off the water often is easy to generate vacuum or is lower than barometric pressure, cause the water siphon backflow phenomenon in the pipe-line system, severe patient may cause the pollution of water supply system.The vacuum breaker of prior art, formed by valve body, safety check and suction valve etc., by destroying the mode of vacuum, prevent the water siphon refluence in the pipeline, solved relevant issues, if but this valve be installed in indoor, in valve open or the process of closing, there is water to splash out by suction port, may indoor facility be damaged.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of and can prevent that the water in the valve from overflowing the novel anti-spilled vacuum breaker of coming.
The utility model solves the problems of the technologies described above and the technological scheme that adopts is: a kind of anti-spilled vacuum breaker, comprise valve body, water intake, water outlet, suction port, check valve assembly, suction valve assembly and bonnet, it is characterized in that: described check valve assembly comprises lower wall, sealing gasket and spring, check valve receptacle is arranged on the valve body, spring is arranged between dish and the lower wall, spring keeps down lower wall and contacts with check valve receptacle and keeps water intake to close, described suction valve assembly comprises dish, sealing gasket and spring, the suction valve valve seat is arranged on the bonnet, spring is arranged between dish and the bonnet, spring keeps down and the disengaging of suction valve valve seat dish, makes suction port keep the air inlet state.
As improvement, described lower wall is provided with support up, and support adopts screw to be connected with lower wall.
As improvement, described bonnet is threaded in the top of valve body, is provided with O type circle between bonnet and the valve body.
As improvement, the top of described valve body is with cover cap, and this cover cap utilizes Philip's head screw to be connected with the top of bonnet.
Compared with prior art, advantage of the present utility model is: be provided with spring between dish and lower wall, guarantee valve open the time, under the effect of spring force, the sealing gasket of last dish contacts with suction valve valve seat on the bonnet, prevent that the water in the pipeline from splashing away from suction port, destroy inside plant.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of anti-spilled vacuum breaker comprises valve body 1, water intake 2, water outlet 3, suction port 4, check valve assembly 5, suction valve assembly 6, bonnet 7 and cover cap 8 as described in Figure 1; Described water intake 2 is arranged on the bottom of valve body 1, and water outlet 3 is arranged on a side of valve body 1, and suction port 4 is arranged on the top of valve body 1, and check valve assembly 5 and suction valve assembly 6 are arranged in the valve pocket; Described check valve assembly 5 comprises lower wall 51, sealing gasket 52 and spring 53; Described suction valve assembly 6 comprises dish 61, sealing gasket 62 and spring 63; Described check valve receptacle 11 is arranged on the valve body 1, and described spring 53 is arranged on lower wall 51 and goes up between the dish 61, and lower wall 51 is kept down, and sealing gasket 52 is contacted with check valve receptacle 11, makes water intake keep closed condition; Described suction valve valve seat 71 is arranged on the bonnet 7, and described spring 63 is arranged between dish 61 and the bonnet 7, and dish 61 is kept down, and sealing gasket 62 and suction valve valve seat 71 are broken away from, and makes suction port be in opening state; Described lower wall 51 is provided with support 54 up, and support 54 adopts screw 55 to be connected with lower wall 51; Described bonnet 7 is threaded in the top of valve body 1, is provided with O type circle 12 between bonnet 7 and the valve body 1; Be provided with cover cap 8 above bonnet 7, the top of this bonnet 7 utilizes countersunk head Philip's head screw 9 to be connected with the center of cover cap 8.
Assembling should be cleaned each part earlier before the utility model, must not have any impurity to bring in the valve body 1, need through the 0.6Mpa air tightness test before coming into operation, pressurize after 15 seconds no any leakage just can normally use.
Working principle of the present utility model is further described.
When water intake 2 water inlet and water flow pressure just often, under the effect of hydraulic pressure, overcome the elastic force of spring 53, check valve receptacle on the valve body 1 separates with sealing gasket 52 on the lower wall 51, safety check is opened, while is under the effect of the elastic force of hydraulic pressure and spring 53, overcome the elastic force of spring 63, it is up mobile that last dish 61 drives sealing gasket 62, and then sealing gasket 62 and the suction valve valve seat 71 on the bonnet 7 are combined closely, suction valve cuts out, and water supply system is separated with air intlet, and anti-sealing overflows, and current are normal in the pipeline at water intake 2 and water outlet 3 places.
When the water flow pressure that does not have water or a water outlet 3 when water intake 2 is higher than the water flow pressure of water intake 2, under the effect of spring 53 elastic force, sealing gasket 52 on the lower wall 51 contacts with check valve receptacle 11 on the valve body 1, closure of check ring, prevent aqueous reflux, simultaneously, spring 63 overcomes the elastic force of spring 53, suction valve valve seat and the sealing gasket on the last dish 61 62 on the bonnet 7 are broken away from, INO, suction port have air to enter, and have destroyed the vacuum in the water system pipeline, prevent water siphon or the backflow of water outlet 3, prevented that well water from causing secondary pollution and prevent from water consumption device or water pump are caused impact of water hammer.
