Embodiment
As shown in Fig. 1 to Fig. 4, a kind of band Nang Bao joint, mainly including joint, water valve 1, spring 2, set screw 3, capsule
Bag 4 and capsule jacket 5 are constituted, and Nang Bao sides wall is provided with multiple fold that can be stretched, and in original state, is full of in capsule bag
Water, Nang Bao fold is in the state somewhat strutted, and joint is threaded on water supply pipe by two ends, in Nang Bao
Put provided with multiple air-vents 51.When the temperature of environment drops to subzero, Nang Bao is due to that outside water supply pipe and can lead to
Air contact of the air-vent directly with the external world is crossed, is easily first frozen than the water in water supply pipe.Because capsule has wrapped fold,
So as to form more spaces between Nang Bao and capsule jacket, the air in the external world is set more to be connect with capsule containment wall face
Touch, so as to be also easier to freeze.
Capsule containment wall is made using sheet metal or sheet rubber, preferably sheet metal, because sheet metal easily transmits heat, works as the external world
Temperature change, it becomes possible to which extraneous temperature change is passed to the water in capsule bag in time.
Outstanding connector 6 is provided with the middle part of joint, provided with inwardly projecting bead at connector and fittings
61, it is provided with drainpipe 62 in connector side；Water valve is made up of water valve bullet and water valve stem, and water valve bullet is located at joint
Interior, water valve stem in joint from connector endoporus is injected, and bead is located at one end in water supply pipe and the water valve taper of water valve
Body formation tight fit, spring housing is provided with tapped adjustment hole on water valve stem on water valve stem；Set screw by nut and
Screw rod, anti-freeze joint also includes piston plate 7, and the external diameter of piston plate is more than the diameter of bore of connector, and piston plate passes through center
Through hole is enclosed on the screw rod of set screw, then the screw rod of set screw is screwable into the adjustment hole on water valve stem, makes spring
One end is against in bead, and the other end is against on piston plate, set screw, piston plate and water valve is fitted together, original state
When, tension force of spring makes the water valve bullet of water valve form tight fit towards the openend of joint with bead, and piston plate leaves company
Joint, to make tension force of spring work, by set screw twist it is tighter a little make spring that there is a certain degree of compression, with
Strengthen the initial tension of spring.Put Nang Bao into capsule jackets again, then capsule jacket is threadedly coupled with connector, by adjusting capsule
The position on connector is wrapped in, Nang Bao roof is close to the nut of set screw.
When environment temperature is more than zero degree, the water in water and capsule bag in water supply pipe is all without icing, and running water
Hydraulic pressure in pipeline is larger, the water valve bullet of water valve will be pressed in bead, therefore, the water in water supply pipe will not
Flow into connector.I.e. when environment temperature is more than zero degree, anti-freeze joint only serves the effect of common water pipe head, and works as environment
When temperature is less than zero degree, anti-freeze joint can just play a part of preventing water supply pipe from freezing.
When environment temperature is dropped to it is subzero when, the water freezing volumetric expansion in capsule bag so that Nang Bao extends, Nang Bao extends just
The set screw fitted together, piston plate and water valve can be pushed up to the direction of joint, piston plate is moved to connector, make
The water valve bullet of water valve leaves bead, and the water in space, joint is produced between water valve and bead between water valve and bead
Space flow into connector, blocked by piston plate, current can only flow away from drainpipe, and drainpipe passes through pipeline and drainage system
It is connected, water is discharged in drainage system, joint and the water in the water supply pipe of joint upstream is in flow regime,
So as to not-easy-to-freeze.
When the water freeze in capsule bag, piston plate can be pushed against onto connector.
Described spring is turriform spring, and bottom of towe is against in bead, and tower top is against on piston plate.
The endoporus formation tight fit of piston plate and capsule jacket, prevents current to be flowed from the space between piston plate and capsule jacket
Below to piston plate, it is to avoid water makes the ice-out in capsule bag when flowing through Nang Bao surfaces.
The central seal groove being outwards recessed provided with a circle in the central through hole of piston plate, around four the week side of boss walls of piston plate
The outer wall seal groove caved inward provided with a circle, the installation center sealing ring in central seal groove is embedded in outer wall seal groove
Upper outer wall sealing ring.Central seal circle prevents current from flowing to capsule from the space between the central through hole and screw rod of piston plate and wrapping,
Outer wall sealing ring prevents space of the current between piston plate and piston bush from flowing to capsule and wrapping.
Described air-vent is elongated hole or circular hole.When the water in capsule bag is liquid, Nang Bao maximum gauge is less than capsule
The diameter of bore 1-3mm of jacket, when the water freezing in capsule bag, makes capsule bag to extend to both sides, the spacing work of receptaculum jacket
With, make capsule bag can only to joint direction extend.
After environment temperature rises to more than zero degree, the ice in capsule bag gradually melts, and Nang Bao length is gradually reduced, spring
Tension force will by the water valve fitted together, piston plate and direction from set screw to Nang Bao push up so that the water valve of water valve
Bullet is pushed against in bead, the water in joint is flowed into connector again.
The aperture of drainpipe is much smaller than the aperture of joint, and effect mainly makes the aquatic products in the water supply pipe of joint upstream
Raw flowing, so that not-easy-to-freeze.
Because the water meter on water supply pipe is easily broken when freezing, therefore, one anti-caking is installed in the downstream of water meter
Ice joint, it becomes possible to play a part of preventing water meter from rupturing.
Above-described embodiment is intended merely to interpretation purposes of the present utility model, and is not to limit of the present utility model
System, those skilled in the art in essential scope of the present utility model, make a variety of changes or substituted, and also should
Belong to protection category of the present utility model.
