Description
Technical field
The utility model relates to pipeline water check valve technical field, more particularly to it is a kind of need not by spring force, utilize pipe
The water check valve of internal pressure automatic water stopping, in particular to a kind of pipe internal pressure automatic flow-stop device.
Background technique
It is well known that there are many current antipriming, the most common tap, check valve etc. are exactly one kind of antipriming
The form of expression.
The water check valve of tap series belongs to except a kind of structure solenoid valve for needing external force to be just able to achieve sealing, single
It is a kind of without external force to valve, spring built in inner utilization realizes the antipriming of pipe plugging.
Check-valves either threeway or two at present on the market is logical, is substantially inside and is equipped with spool, then spool edge
Valve rod displacement, the spring that the power for blocking pipe is internally sourced use for a long time, spring gets rusty, one side shadow
Xiangshui County's matter, while it being easily broken off failure, gently then there is closure mouth and drips, then occurs the phenomenon that can not blocking again.
At present in the pipe installation process such as hot-water heating, the closure of pipe end temporarily or permanently can all be twisted in pipe end
Enter plug, plug some is using being threadedly coupled, and some is using being thermally connected, and no matter which kind of is connected, and when reopening, needs to seal
It is stifled to remove, then in other water fetching devices such as access tap, in this process, it is also necessary to close the main valve on pipeline
Fall, to facilitate the installation of the water fetching devices such as tap, while also avoiding the waste of tap water resource during the installation process, but
It is the main valve installation site on general pipeline than more covert, some is additionally arranged at outdoor certain places, operates very cumbersome.
There are also a kind of situation, tap use throughout the year may generate drainage, will cause water if repaired not in time
The waste of resource, at present traditional water pipe when in use, generally in elbow or the upper accepting water of threeway faucet or other intake equipments,
Generally there are two types of forms for elbow or threeway, and a kind of to have nested structure to be internal, another kind is light wall construction, according to different
Requirement uses different forms, can be used directly with nested, is thermally connected without nested can using or external
Thread bush etc..
Sealing described above is only a kind of representative of working fluid, a series of liquid medium or gas medium
Flowing is common to the description and expression of this programme.
Summary of the invention
The technical problems to be solved in the utility model is provided in a kind of pipe for existing deficiencies in the technology
Press automatic flow-stop device:
