Abstract

The utility model relates to the field of non-negative pressure valves, in particular to a non-negative pressure valve of a non-negative pressure tank. The non-negative pressure valve comprises a non-negative pressure valve body, a sealing ring, a dustproof screen layer and a filter screen layer, wherein the non-negative pressure valve body is arranged on the top of the non-negative pressure tank and comprises a valve base and a valve rod; the sealing ring is sleeved on the valve rod and is arranged at the bottom of the valve base; the dustproof screen layer is arranged on the upper part of an inner cavity of the valve rod; and the filter screen layer is arranged at the bottom of the inner cavity of the valve rod. According to the non-negative pressure valve, the sealing ring is arranged on the valve rod of the non-negative pressure valve body, the dustproof screen layer is arranged in the middle part of the inner cavity of the valve rod, and the filter screen layer is arranged at the bottom of the valve rod. The non-negative pressure valve is simple in structure and low in cost, and can be prevented from being influenced by the external environment to the greatest extent, so that the physical health of a person is ensured.

Description

A kind of non-negative pressure valve of pot with no negative pressure

Technical field

The utility model relates to the non-negative pressure valve field, is specifically related to a kind of non-negative pressure valve of pot with no negative pressure.

Background technique

The resident family of high-rise building is when using tap water now, and due to the master, the underpressure of city planting ductwork when the water supply peak causes the water of high-rise buildings difficult, and the supply that the way of dealing with problems adopts pot with no negative pressure to keep tap water; This way of ordinary circumstance is to adopt at the pot with no negative pressure top non-negative pressure valve is set, and the work by non-negative pressure valve keeps the water level of pot with no negative pressure normal, thereby guarantees the use of the tap water of high-rise buildings; But because the non-negative pressure valve body is arranged on the pot with no negative pressure outside, thereby be subject to the impact of dust in external environment condition, sewage, form secondary pollution thereby form to tap water, affect the healthy of people.

The model utility content

The purpose of this utility model is for the defective of prior art and deficiency, provide a kind of simple in structure, the non-negative pressure valve of a kind of pot with no negative pressure reasonable in design, easy to use, on the valve rod of its employing non-negative pressure valve body, seal ring is set, be provided with dustproof stratum reticulare in the middle part of stem cavity, in stem bottom, the filtration stratum reticulare be set; It is simple in structure, and cost is low, can guarantee to greatest extent that non-negative pressure valve is not subjected to the impact of external environment condition, thereby to need to guarantee that people's is healthy.

For achieving the above object, the technical solution adopted in the utility model is:

The non-negative pressure valve of a kind of pot with no negative pressure described in the utility model comprises the non-negative pressure valve body, and described non-negative pressure valve body is arranged on the pot with no negative pressure top; Described non-negative pressure valve body comprises valve base and valve rod, and it also comprises seal ring, dustproof stratum reticulare and filtration stratum reticulare, and described seal ring is set on valve rod, on the sealing circle is arranged on bottom valve base; Described dustproof stratum reticulare is arranged on the inner chamber top of valve rod; Described filtration stratum reticulare is arranged on the intracavity bottom of valve rod.

Further, the material of described dustproof stratum reticulare adopts metallic steel.

After adopting said structure, the utility model beneficial effect is: on the valve rod of its employing non-negative pressure valve body of the utility model, seal ring is set, is provided with dustproof stratum reticulare in the middle part of stem cavity, in stem bottom, the filtration stratum reticulare is set; It is simple in structure, and cost is low, can guarantee to greatest extent that non-negative pressure valve is not subjected to the impact of external environment condition, thereby to need to guarantee that people's is healthy.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, 2, the non-negative pressure valve of a kind of pot with no negative pressure described in the utility model comprises non-negative pressure valve body 1, and described non-negative pressure valve body 1 is arranged on pot with no negative pressure 2 tops; Described non-negative pressure valve body 1 comprises valve base 11 and valve rod 12, and it also comprises seal ring 13, dustproof stratum reticulare 14 and filter stratum reticulare 15, and described seal ring 13 is set on valve rod 12, and sealing circle 13 is arranged on valve base 11 bottoms; Described dustproof stratum reticulare 14 is arranged on the inner chamber top of valve rod 12; Described filtration stratum reticulare 15 is arranged on the intracavity bottom of valve rod 12.

As another kind of optimal way of the present utility model, the material of described dustproof stratum reticulare 14 adopts metallic steel.

On the valve rod of its employing non-negative pressure valve body of the utility model, seal ring is set, is provided with dustproof stratum reticulare in the middle part of stem cavity, in stem bottom, the filtration stratum reticulare is set; It is simple in structure, and cost is low, can guarantee to greatest extent that non-negative pressure valve is not subjected to the impact of external environment condition, thereby to need to guarantee that people's is healthy.

The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
