Abstract

The utility model discloses a kind of tank seal connector, the seal nipple includes casing and clamp nut, and the internal diameter of described sleeve pipe is adapted with the outer diameter of built-in heat exchanger conduit, and one end of casing is fixedly connected on inner water tank;It is equipped with annular groove at the end face of the other end and heat exchanger guiding-tube cooperation, is equipped with sealing ring in a ring groove, the external screw thread for being used to fit sealing circle with clamp nut cooperation is equipped on the outer wall of the other end.The seal nipple, sealing effect is good, and manufacturing cost is low, durable, and use is reliable and secure.

Description

A kind of tank seal connector
Technical field
The utility model relates to a kind of heat storage water tank, specifically a kind of sealing of built-in heat exchanger bearing hot water tank Connector.
Background technique
Conventionally, as the limitation that electric heater and solar water heater use, heat pump water heater are more next More it is taken seriously.And in heat pump water heater, it needs to place heat exchanger in cabinets cavity, to guarantee sealing effect, in cabinet Both ends need to be equipped with the attachment device for being used to install built-in heat exchanger.It is good currently without a kind of sealing effect and manufacturing process is simple Single attachment device.
Summary of the invention
The purpose of the utility model is to provide a kind of tank seal connectors, and the seal nipple, sealing effect is good, manufacturing cost Low, durable, use is reliable and secure.
The purpose of this utility model is achieved through the following technical solutions:
A kind of tank seal connector, it is characterised in that: the seal nipple includes casing and clamp nut, described sleeve pipe Internal diameter is adapted with the outer diameter of built-in heat exchanger conduit, and one end of casing is fixedly connected on inner water tank;The end face of the other end With at heat exchanger guiding-tube cooperation be equipped with annular groove, in a ring groove be equipped with sealing ring, on the outer wall of the other end be equipped with and compression Nut cooperation is used to the external screw thread of fit sealing circle.
Further, liner is made of plastic pouring, and one end of casing is cast directly on liner.
The clamp nut lower ending opening is big, and upper end opening is small, and the internal diameter of lower end is adapted with sleeve outer, upper end it is interior Diameter is adapted with heat exchanger guiding-tube outer diameter.
For heat-pump-type water tank, needs to place heat exchanger in cabinets cavity, to guarantee sealing effect, be equipped in tank ends With tank seal connector.Sealing ring can be tightly stuck on heat exchanger guiding-tube by clamp nut.
Compared with prior art, the seal nipple, sealing effect is good, and manufacturing cost is low, durable, uses reliable peace Entirely.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is that the utility model uses schematic diagram in single-chamber body water tank.
Fig. 3 is that the utility model uses schematic diagram in two cavity water tanks.
Specific embodiment
A kind of tank seal connector, is shown in Fig. 1, and the seal nipple includes casing 1 and clamp nut 2, described sleeve pipe it is interior Diameter is adapted with the outer diameter of built-in heat exchanger conduit 3, and one end of casing is fixedly connected on inner water tank 4;The end face of the other end With at heat exchanger guiding-tube cooperation be equipped with annular groove 11, in a ring groove be equipped with sealing ring 5, on the outer wall of the other end be equipped with and pressure Tight nut cooperation is used to the external screw thread 6 of fit sealing circle.The clamp nut lower ending opening is big, and upper end opening is small, lower end it is interior Diameter is adapted with sleeve outer, and the internal diameter of upper end is adapted with heat exchanger guiding-tube outer diameter, can be tight by sealing ring by clamp nut Tightly it is stuck on heat exchanger guiding-tube outer diameter.
It for heat-pump-type all-plastic liner bearing hot water tank, needs to place heat exchanger in cabinets cavity, to guarantee sealing Effect is equipped with seal nipple in tank ends subregion, sees Fig. 2.Inner water tank is plastic tube tube structure, is made of plastic pouring, One group of reinforcing rib 7 is uniformly surrounded in plastic tube tube internal layer.One end of casing 1 is cast directly on liner.
For expansion volume and preferably using the hot water in water tank, multiple liners can be linked together use, adjacent Two liners are connected by deflector hole.Fig. 3 is the schematic diagram of two inner water tank embodiments.In Fig. 3, it is equipped in the water tank of lower section Heat exchanger 8, water inlet are located below the bottom of box, and water outlet is located above the top of cabinet.
