Abstract
The utility model discloses a kind of explosion stack volitional check valve, mainly comprise valve body outlet pipe, intake pipe, crossbeam, spring and valve plate, described intake pipe, valve body are connected successively with outlet pipe, vertical crossbeam is provided with in described valve body, one end of linking springs in the middle part of described crossbeam, the other end of described spring is fixedly connected with described valve plate; The diameter of described pipeline is less than the diameter of described valve plate; Described valve plate is located at described intake pipe side.This explosion stack volitional check valve, by responding to pressure change when normal water flowing and water pipe explosion, realizing quick closedown, can block current, protect family's property.The utility model structure is simple, easy to use, can be applied in conduit pipeline and HVAC, and anti-water stopping tube bursts the loss caused.
Description
Technical field
The utility model relates to a kind of articles for daily use, more particularly, relates to a kind of explosion stack volitional check valve.
Background technique
Because Modern Family has because the pipeline burst that causes of the quality of running water pipe and radiator and problem of aging, cause damage to family's property, also can waste certain water resources simultaneously.
Therefore, owing to there is above-mentioned technological deficiency in prior art, be those skilled in that art's technical problems urgently to be resolved hurrily.
Model utility content
The purpose of this utility model, for providing a kind of explosion stack volitional check valve, is intended to solve in prior art the above-mentioned defect and problem that exist.
For achieving the above object, the utility model provides following technological scheme:
A kind of explosion stack volitional check valve, mainly comprise valve body, outlet pipe, intake pipe, crossbeam, spring and valve plate, described intake pipe, valve body are connected successively with outlet pipe, vertical crossbeam is provided with in described valve body, one end of linking springs in the middle part of described crossbeam, the other end of described spring is fixedly connected with described valve plate.
Preferably, the diameter of described pipeline is less than the diameter of described valve plate, the outlet pipe that described pipeline refers to and intake pipe.
Preferably, described valve plate is located at described intake pipe side.
The beneficial effects of the utility model are: this explosion stack volitional check valve, by responding to pressure change when normal water flowing and water pipe explosion, realizing quick closedown, can block current, protect family's property.The utility model structure is simple, easy to use, can be applied in conduit pipeline and HVAC, and anti-water stopping tube bursts the loss caused.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
In figure: 1 is valve body; 2 is outlet pipe; 3 is intake pipe; 4 is crossbeam; 5 is spring; 6 is valve plate.
Embodiment
The utility model provides a kind of explosion stack volitional check valve, and the utility model structure is simple, easy to use, can be applied in conduit pipeline and HVAC, and anti-water stopping tube bursts the loss caused.
Below in conjunction with the accompanying drawing in the utility model embodiment, carry out clear and detailed description to the technological scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of explosion stack volitional check valve as shown in Figure 1, mainly comprise valve body 1, outlet pipe 2, intake pipe 3, crossbeam 4, spring 5 and valve plate 6, described intake pipe 3, valve body 1 is connected successively with outlet pipe 2, the structure of a composition water flowing, vertical crossbeam 4 is provided with in described valve body 1, the flowing of water can not be hindered, one end of linking springs 5 in the middle part of described crossbeam 4, by increasing and decreasing the methods such as the material of spring 5 quantity or replacing spring 5, spring 5 is set when normal current, there will not be flexible, normal water flowing can be carried out, the other end of described spring 5 is fixedly connected with described valve plate 6, and become suddenly anxious at current, when causing the hydraulic pressure in intake pipe 3 and outlet pipe 2 to change, water now in intake pipe 3 promotes valve plate 6 and is subjected to displacement, thus spring 5 is compressed, the diameter of described intake pipe 3 and outlet pipe 2 is less than the diameter of described valve plate 6, thus when valve plate 6 is moved, valve plate 6 can by line clogging, thus prevent current from further revealing.Described valve plate 6 is located at described intake pipe 3 side.Can by this valve body 1 structure in ventilating water pipe or in heating and ventilating pipeline, thus can when explosion occurs water pipe, timely blocking pipe, prevents from causing any property loss.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.Be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
