Floating ball exhaust valve disclosed in ZL201020033409.0 etc., sealing element are that floating ball is floated when valve body does not have gas by water
Power levitating, gas vent is closed, and when exhaust, water level decreasing in valve body, floating ball decline is exposed gas vent and is exhausted.
Since exhaust valve is for hankering being frequently utilized in the equipment such as heat supplying pipeline, boiler, water heater, water temperature is higher, and its
For internal sealing element due to the needs of sealing, material is often the soft material of rubber etc, is repeatedly subjected to high temperature in exhaust
The impact of water makes it be very easy to temperature distortion, so that loss of seal, makes the hot water in relevant device outflow, not only influence
It uses, and will cause great waste.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides one kind can keep excellent sealing for a long time in heating equipment
The exhaust valve of property.
The technical solution adopted in the utility model is: a kind of exhaust valve, including internal valve body up and down, valve inner
Be provided with spool with gas vent and with the matched sealing element of spool, it is characterized in that: sealing element bottom setting hard
Water barrier.
A kind of exhaust valve, it is characterized in that: the sealing element is the sealing ring of annular, the water barrier be it is round or
Circular cylindrical body.
A kind of exhaust valve, it is characterized in that: the sealing ring matches setting guiding axis, the guiding axis with water barrier
It fixes or is fixed on spool with the sealing ring, water barrier, when guiding axis and fixed sealing ring, water barrier, set on spool
It is equipped with and the matched pilot hole of guiding axis.
A kind of exhaust valve, it is characterized in that: discharge outlet is arranged in the body wall, the draining open height is described
On spool.
Water barrier is arranged on the basis of original exhaust valve in the utility model below sealing element, can effectively stop to be vented
When high-temperature water impact, thus greatly extend sealing element service life.

Specific embodiment
Embodiment one:
As shown in Figure 1, a kind of exhaust valve, including lower valve body 1 and upper valve body 2, it is provided with spool 3 with holes in lower valve body 1,
Spool 3 is matched with sealing element 4, and sealing element 4 is circular cylindrical shape body, and 4 bottom of sealing element is water barrier 5, water barrier 5 and sealing element 4
Lower surface fitting.
When being vented valve exhaust, sealing element 4 is separated with spool 3 under the effect of gravity, and gas is discharged by the hole on spool,
As gas is discharged, horizontal plane constantly rises to water barrier 5, and water barrier is risen by buoyant belt dynamic seal, until and valve
Core fitting, prevents water from overflowing.
Embodiment two:
As shown in Fig. 2, a kind of exhaust valve, including lower valve body 1 and upper valve body 2, it is provided with spool 3 with holes in lower valve body 1,
Spool 3 is matched with sealing element 4, and sealing element 4 is circular cylindrical shape body, and 4 bottom of sealing element is water barrier 5, water barrier 5 and sealing element 4
Lower surface fitting, 2 side wall of upper valve body are provided with discharge outlet 6.
When being vented valve exhaust, sealing element 4 is separated with spool 3 under the effect of gravity, and gas is discharged by the hole on spool,
As gas is discharged, horizontal plane constantly rises to water barrier 5, and water barrier is risen by buoyant belt dynamic seal, until and valve
Core fitting, prevents water from overflowing.In exhaust valve long-term use process, due to Water vapor condensation or leakage etc., in upper valve body not
It is evitable to generate ponding, when ponding reaches it is a certain amount of when, can be discharged by discharge outlet 6, discharge outlet 6 can be separately provided, or
Water return pipeline is connected to recycle.
Embodiment three:
As shown in figure 3, a kind of exhaust valve, including lower valve body 1 and upper valve body 2, it is provided with spool 3 with holes in lower valve body 1,
Spool 3 is matched with sealing element 4, and sealing element 4 is circular cylindrical body, and 4 bottom of sealing element is water barrier 5, water barrier 5 and sealing element 4
Lower surface fitting, 3 bottom center position of spool are provided with guiding axis 7, and sealing element 4, water barrier 5 are placed on guiding axis 7, upper valve body
2 side walls are provided with discharge outlet 6.
When being vented valve exhaust, sealing element 4 is separated with spool 3 under the effect of gravity, and gas is discharged by the hole on spool,
As gas is discharged, horizontal plane constantly rises to water barrier 5, and water barrier is risen by buoyant belt dynamic seal, until and valve
Core fitting, prevents water from overflowing, and when sealing element moves up and down, guiding axis can make its guarantee horizontal, to reduce spool and sealing element
The fitting time, further avoid spilling water phenomenon.In exhaust valve long-term use process, due to originals such as Water vapor condensation or leakages
Cause inevitably generates ponding in upper valve body, when ponding reaches it is a certain amount of when, can be discharged by discharge outlet 6, discharge outlet 6
It can be separately provided, or connection water return pipeline recycles.
Example IV:
As shown in figure 4, a kind of exhaust valve, including lower valve body 1 and upper valve body 2, it is provided with spool 3 with holes in lower valve body 1,
Spool 3 is matched with sealing element 4, and sealing element 4 is circular cylindrical body, and 4 bottom of sealing element is water barrier 5, and water barrier 5 is circular cylindrical shape
Body, center are provided with guiding axis 7, and 3 bottom centre position of spool is provided with and the matched pilot hole 8 of guiding axis 7, water barrier
5 are bonded with 4 lower surface of sealing element, and guiding axis 7 protrudes into pilot hole 8, and 2 side wall of upper valve body is provided with discharge outlet 6.
When being vented valve exhaust, sealing element 4 is separated with spool 3 under the effect of gravity, and gas is discharged by the hole on spool,
As gas is discharged, horizontal plane constantly rises to water barrier 5, and water barrier is risen by buoyant belt dynamic seal, until and valve
Core fitting, prevents water from overflowing, and when sealing element moves up and down, guiding axis and pilot hole can make its guarantee horizontal, to reduce spool
It is bonded the time with sealing element, further avoids spilling water phenomenon.In exhaust valve long-term use process, due to Water vapor condensation or infiltration
The reasons such as leakage inevitably generate ponding in upper valve body, when ponding reaches it is a certain amount of when, can be discharged, be arranged by discharge outlet 6
The mouth of a river 6 can be separately provided, or connection water return pipeline recycles.
