Description
Technical field
The present invention relates to valve technology fields, and in particular to a kind of water meter protection valve.
Background technique
China is a water shortage country, and in daily life, as soon as our water wrings are leading, water is continuously flowed out,
The crisis of possible at all imperceptible water.But in fact, the water that we depend on for existence, positive increasingly in short supply.Controlling water supply leakage loss is
The one of the important signs that for creating slug fluidization, it is estimated that the pipe network model rate average out to of China's city public water supply system
21.5%.Therefore, the leak rate for how reducing public supply mains, the waste for reducing water resource have become weight in water supply work
In it is weight.Reducing water supply network leak rate is even more the effective way for saving water resource.Valve before domestic consumer's water meter is frequently sent out
The phenomenon that raw water clock, causes a large amount of wastes and economic loss of water resource.
To be usually copper locking gate valve as water meter protect valve to come using but due to China's copper with valve before table domestic at present
Gate valve material is brass, and lead content is too high, not can guarantee urbanite water consumption safety, while the valve can not solve tap water clock
Problem occurs dripping causing the loss of water resource the case where table is not walked.Valve can not be solved because of pipe network pressure difference before existing table simultaneously
Caused by water meter rotation and the phenomenon that reversion, and the rotation of water meter and reversion led to the not accurate of the data of water meter and using the longevity
Shortening for life, causes the complaint of user.
Summary of the invention
Based on the above issues, water meter rotation and anti-caused by can solve it is an object of that present invention to provide one kind because of pipe network pressure difference
Turn phenomenon, while valve minimum starting flow is greater than the minimum starting flow of water meter, is able to solve urbanite water consumption and water clock occurs
Water meter protects valve.
In view of the above problems, providing following technical solution: a kind of water meter protects valve, including valve body, valve deck, valve rod and
The flashboard being connected with valve rod bottom end, the valve body both ends are respectively equipped with water inlet end and water outlet, are equipped in the valve body for being situated between
The logical pipelined channel of mass flow, the interior side positioned at flashboard with respect to water outlet of the valve body are equipped with the sky being connected with pipelined channel
Chamber；It further include non-return mechanism, the non-return mechanism includes spool, is located in cavity and is sequentially sleeved on spool towards water outlet
Sealing ring, pressure ring, spring and positioning ring, the outer circle wall of the spool, which is equipped with, to be located in pipelined channel and and sealing ring
The bulge loop to offset, the sealing ring are located at the connectivity part of pipelined channel and cavity, and connection and cutting for controlling the two, institute
The both ends for stating spring are butted on respectively on pressure ring and positioning ring, and the port being connected with cavity is offered on the positioning ring, described
Spool is reciprocally displaced towards positioning ring, and the water outlet is equipped with the connector being threadedly coupled with it, and the connector is equipped with
The through-hole being connected with pipelined channel.
In above structure, the present invention is installed on the pipeline before water meter, flashboard is controlled by rotation valve rod with realize into
The circulation or cutting of water end (W.E.) and water outlet.When opening valve, tap water enters in pipelined channel from water inlet end, and tap water is to bulge loop
