Background

The exhaust valve is applied to exhaust of pipelines such as an independent heating system, a central heating system, a heating boiler, a central air conditioner, a floor heating system, a solar heating system and the like. When gas overflows from the system, the gas ascends along the pipeline and finally gathers at the highest point of the system, the exhaust valve is generally arranged at the highest point of the system, when the gas enters the valve cavity of the exhaust valve and gathers at the upper part of the exhaust valve, the pressure rises along with the increase of the gas in the valve, when the gas pressure is higher than the system pressure, the gas can enable the water surface in the cavity to fall, the floating ball falls along with the water level, and the exhaust port is opened; after the gas is exhausted, the water level rises, the floating ball also rises, and the exhaust port is closed. In the same way, when negative pressure is generated in the system, the water level in the valve cavity is lowered, the exhaust port is opened, and the outside atmospheric pressure is higher than the system pressure, so that the atmosphere can enter the system through the exhaust port, and the negative pressure is prevented from being damaged.

However, in the pipeline structures such as the heating system, a large amount of impurities are generated along with the prolonging of the service life, and the impurities gradually accumulate along with the medium entering the valve cavity of the exhaust valve, so that a floating ball and an exhaust port inside the exhaust valve are polluted, the accumulation and corrosion of the impurities are caused, the tightness of the exhaust valve is damaged, the gas leakage or the gas cannot be discharged is caused, the use of equipment is influenced, and even dangerous conditions such as overhigh pressure inside the pipeline are generated.

fig. 2 is a schematic structural view of the vibration device according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. Based on the embodiments only in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1-2, an exhaust valve 1 filters impurity structure acts on exhaust valve 1, exhaust valve 1 includes a valve cavity 10, an exhaust port 11 is opened above valve cavity 10, a sealing ring 12 is fixed at exhaust port 11, a floating ball 13 is placed inside valve cavity 10, a filter screen 14 is arranged at the periphery of floating ball 13 in the inner cavity of valve cavity 10, the bottom of filter screen 14 is connected with valve cavity 10 through a vibrating device 15, vibrating device 15 includes a vertically arranged vibrating spring 151, and a resistance plate 152 is inserted and fixed in the middle of vibrating spring 151.

When the structure is used, along with the operation of the exhaust valve 1, the liquid level inside the valve cavity 10 is constantly changed, and a medium constantly flows through the filter screen 14, so that impurities are blocked outside the exhaust valve 1 by the filter screen 14; and in the flowing process, the vibration device 15 can vibrate along with the water flow, so that the whole filter screen 14 is driven to vibrate, and impurities are prevented from being attached to the filter screen 14. And the number of the vibration devices 15 is plural. The vibration effect can be ensured to be stronger under the condition that the filter screen 14 is ensured to be safely connected with the valve cavity 10. And the force-receiving area of the resistance plate 152 is larger than that of the vibration spring 151, and the acting force is stronger, so that the vibration strength is increased.

Wherein, the lower extreme of vibrating spring 151 is fixed with screw assembly 153, the water inlet department of discharge valve 1 offers the screw assembly 153 with screw assembly 153 matching, vibrating spring 151 is fixed in the water inlet department of discharge valve 1 through being connected of screw assembly 153 and screw assembly 153. Therefore, when the exhaust valve 1 is detached for maintenance, the vibration device 15 can be detached for maintenance in the same manner, and the service life is prolonged.

And, because the exhaust valve 1 is generally disposed above the system, the water flow generally moves up and down inside the exhaust valve 1, so the resistance plate 152 is disposed horizontally, the contact area and the acting force are increased, and the number of the resistance plates 152 is plural, and the resistance plates are inserted and fixed on the vibration spring 151 at intervals, thereby enhancing the vibration frequency and effect of the vibration spring 151. The vibration spring 151 is a light spring, and thus can be driven to vibrate by water flow. And the whole vibration device 15 is made of corrosion-resistant alloy materials, so that the influence on the action effect caused by medium corrosion is prevented.

The above is only the preferred embodiment of the present invention, and any person can make some simple modifications, deformations and equivalent replacements according to the present invention, all fall into the protection scope of the present invention.
