And the water in the water supply pipe of joint upstream is in flow regime, so that not-easy-to-freeze rupture water pipe.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the invention；
Fig. 2 is the figure that pops of the invention；
Fig. 3 is generalized section when water in capsule of the present invention does not freeze；
Generalized section when Fig. 4 is the water freezing in capsule of the present invention.
Specific embodiment
As shown in Fig. 1 to Fig. 4, a kind of anti-freeze joint, mainly including joint, water valve 1, spring 2, set screw 3, capsule
4 and capsule set 5 constitute, capsule be elastic material make, in capsule be full of water, the threaded connection that joint passes through two ends
On water supply pipe, multiple air-vents 51 are provided with capsule set.When the temperature of environment drops to subzero, capsule is due to being located at
Outside water supply pipe and can by air-vent directly with extraneous air contact, easily first tied than the water in water supply pipe
Ice.
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 capsule into capsule set again, then capsule set is threadedly coupled with connector, by adjusting glue
Position of the cuff on connector, makes capsule be close to the nut of set screw.
When environment temperature is more than zero degree, the water in water and capsule 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 in capsule extends capsule, capsule elongation will will be assembled in one
Set screw, piston plate and the water valve for rising are pushed up to the direction of joint, piston plate is moved to connector, bore the water valve of water valve
Body leaves bead, and space is produced between water valve and bead, and space of the water in joint between water valve and bead flows into company
Joint, is blocked by piston plate, and current can only flow away from drainpipe, and drainpipe is connected by pipeline with drainage system, and water is arranged
To in drainage system, joint and the water in the water supply pipe of joint upstream is set to be in flow regime, so as to be difficult knot
Ice.
When the water freeze in capsule, 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 set, current is flowed from the space between piston plate and capsule set
To piston plate lower section, it is to avoid water makes the ice-out in capsule when flowing through capsule surface.
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 current from being flowed on capsule from the space between the central through hole and screw rod of piston plate,
Outer wall sealing ring prevents space of the current between piston plate and piston bush from flowing on capsule.
Described air-vent is elongated hole or circular hole.When the water in capsule is liquid, the diameter of capsule is less than capsule set
Diameter of bore 1-3mm, when the water freezing in capsule, capsule is extended to both sides, by the position-limiting action of capsule set, make
Capsule can only extend to the direction of water valve.
After environment temperature rises to above zero, the ice in capsule gradually melts, and the length of capsule is gradually reduced, spring
Tension force will by direction from piston plate to capsule push up so that the water valve bullet of water valve is pushed against in bead, make in joint
Water can not again flow 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.
