Description
Technical field
The present invention relates to a kind of locking antidrip ball check valve, belong to the valve technology field with spherical surface stopper.
Background technology
Ball check valve is a kind of non-return structure completing that got off by the collective effect of check valve spool body and ball valve, this valve
Can only one-way flow a kind of non-return structure.Existing product structure, in conjunction with Fig. 1, mainly by ball valve 1a, sealing gasket 2a, non-return
Valve flap 3a, valve body 4a and attaching nut 5a are constituted, and check-valves flap 3a therein only has single check function, works as user
In the case of the use water of very little metering, water meter does not rotate and does not measure, thus leading to property and waterworks virtually a kind of economical
Loss.While water resource critical shortage, Residents drip use, that water meter does not measure, water rate collects the phenomenons such as difficulty is quite general
Time, result in the significant wastage of water resource, exacerbate the imbalance between supply and demand of water resource.
Based on this, make the application.
Content of the invention
In order to solve Residents in the case of water resource critical shortage drip use, water meter does not measure, water rate collects difficulty
Etc. phenomenon, result in the significant wastage of water resource, exacerbate the imbalance between supply and demand of water resource, and improve waterworks or property water supply
Economic benefit and management and control, the application JP sends out locking antidrip ball check valve a kind of, even if the situation in very little flow water
Under, also can cut off current, thus reaching drip-proof function.
For achieving the above object, the technical scheme that this application takes is as follows：
A kind of locking antidrip ball check valve, including band spherical ball valve, flap seat, valve petal shelf, spring and check valve body, check valve body
It is connected with band spherical ball valve, flap seat, valve petal shelf and spring are arranged in check valve body, and described flap seat is arranged on band spherical ball valve
And valve petal shelf between；Between valve petal shelf and flap seat, sealing gasket is installed；Spring is set with valve petal shelf.
Further, as preferred：
Described flap seat is set to the conical surface towards one end of valve petal shelf.It is furthermore preferred that described sealing gasket includes the inner with outward
End, inner is fixing end, and this end is arranged on valve petal shelf, and outer end is movable end, and this end is installed on inside the conical surface.
Described check valve body is fixed by attaching nut.
It is provided with key, for controlling the opening and closing with spherical ball valve above described band spherical ball valve.
It is set with O-ring between described flap seat and band spherical ball valve, play sealing function.
Described valve petal shelf is the font structure of falling T, and including perpendicular end and horizontal end, it is perpendicular end towards one end of flap seat, erects
Fixing groove is provided with end, sealing gasket makes its inner be fixed on valve petal shelf by this fixing groove, and spring is sleeved on horizontal end.More
Preferably, described perpendicular end is arranged fluted, spring one end is fixed in this groove, and the other end then forms movable end.
It is provided with parting bead, spring is located between parting bead and valve petal shelf in described check valve body.It is furthermore preferred that described every
Through hole is transversely provided through on bar, this through hole is correspondingly arranged with the horizontal end of valve petal shelf.
The application locking goes back on defense water clock ball check valve, substantially increases the management of Running-water Company and property.And should
Locking goes back on defense water clock ball-valve structure by under the flap seat with the conical surface and the valve petal shelf with sealing gasket and spring collective effect power,
When the pressure of current is more than the active force of spring and flap seat sealing gasket, current push check-valves open, and check-valves are opened.；When little
The pressure of flow current is less than the active force of spring and flap seat sealing gasket, closure of check ring, at this moment drip-proof function can in case
Only drip use, water meter of resident such as does not measure at the bad phenomenon, thus reaching the intransitable purpose of low discharge, this valve achieves antidrip
The function of leakage check-valves.
In the case of user stays out or be dry, online in running water pipe in parallel, because other users are with water
The siphonage of Shi Zaocheng, the water meter being fitted without this check valve has rotation idle running phenomenon, and after installing this valve, this rotation is empty
Turn phenomenon to eliminate, thus prevent user dry in the case of water meter rotation idle running lead to the economic loss of user's water.
When user is not in the case of arrearage or artificially handing over water rate, property or Running-water Company can be entered to ball valve with key
Row locking, efficiently solves the imbalance between supply and demand of property or Running-water Company and user, substantially increases property or Running-water Company
Management and control ability to user's water, thus convenient manage.
Ball check valve set by the application, valve petal shelf, spring, sealing gasket and flap seat constitute Anti-drip-leakage mechanism, are not required to
Separately installed dripping-free valve is it is achieved that the function of multi-purpose valve.When discharge is more than the normal metered flow of water meter, valve element
Normally-open；When discharge is trickle, when being in water clock flow, then valve element internally will turn off under the pressure of spring, non-return
Valve body is not connected with band spherical ball valve, that is, cut off flow, thus reaching drip-proof function.This antidrip ball valve is applied to all size
Rotor water gauge, this valve flow through water meter each drip be attained by measure purpose, and after table can be prevented be situated between
Rotation that matter flows backwards and water meter dallies,
The operation principle of the ball check valve that the application is adopted is：Check-valves refer to rely on medium itself to flow and automatic open and close
Flap, for the valve preventing medium from flowing backwards, also known as non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belong to a kind of
Automatic valve, its Main Function is to prevent medium from flowing backwards, prevent pump and drive motor reversion, and the releasing of vessel media.
This valve mainly includes a kind of table early gate of resident living area pipe network with supply and drain water system, and main preventing and treating resident drips
With, water meter does not measure, water rate collects difficulty, water meter dally rotation use water occasion.
