Specific embodiment
As shown in Fig. 1 to Fig. 4, a kind of joint with Nang Bao, 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, the fold of Nang Bao is in the state for somewhat being strutted, and joint is threaded on water supply pipe by two ends, in Nang Bao
Put and be 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
Cross air-vent directly with extraneous air contact, 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.
Joint middle part is provided with connector 6 outwardly, and inwardly projecting bead is provided with 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, from connector endoporus is injected in joint, bead is located at the water valve taper of the one end and water valve in water supply pipe to water valve stem
Body forms tight fit, and 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 diameter of bore of the external diameter more than connector of piston plate, piston plate passes through center
Through hole is enclosed within 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 and bead form tight fit towards the openend of joint, 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, the roof of Nang Bao 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, and 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 to prevent 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 extend, Nang Bao extend just
Set screw, piston plate and the water valve that will can be fitted together are pushed up to the direction of joint, piston plate is moved to connector, are made
The water valve bullet of water valve leaves bead, and space is produced between water valve and bead, and the water in joint is between water valve and bead
Space flow into connector, blocked by piston plate, current can only flow away from drainpipe, drainpipe pass 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.
Piston plate forms tight fit with the endoporus of capsule jacket, current is flowed from the space between piston plate and capsule jacket
To piston plate lower section, it is to avoid water makes the ice-out in capsule bag when flowing through Nang Bao surfaces.
The central seal groove that a circle is outwards recessed is provided with the central through hole of piston plate, around four the week side of boss walls of piston plate
The outer wall seal groove that a circle caves inward is provided with, 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 from current from flowing to capsule from the space between the central through hole and screw rod of piston plate wrapping,
Outer wall sealing ring prevents from space of the current between piston plate and piston bush from flowing to capsule wrapping.
Described air-vent is elongated hole or circular hole.When the water in capsule bag is liquid, the maximum gauge of Nang Bao 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 above zero, the ice in capsule bag gradually melts, and the length of Nang Bao is gradually reduced, spring
Tension force water valve, piston plate and the set screw that will will fit together pushed up to the direction of Nang Bao so that the water valve of water valve
Bullet is pushed against in bead, the water in joint is again flowed into connector.
The aperture of drainpipe acts on the aquatic products mainly made in the water supply pipe of joint upstream much smaller than the aperture of joint
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 to prevent water meter from rupturing.
Above-described embodiment is intended merely to interpretation purposes of the invention, and is not limitation of the present invention, this technology
The those of ordinary skill in field, in essential scope of the invention, makes a variety of changes or substitutes, and should also belong to guarantor of the invention
Shield category.
