Abstract
The invention discloses a sealing structure. The sealing structure comprises a guide tube and a connecting component. The cylindrical guide tube is arranged in a mounting hole of a water tank, so that an inner cavity of the water tank is communicated with the outside. The connecting component comprises an external thread part, a nut, a seal ring, a compression end cover and a compression nut. The guide tube is sleeved with the external thread part, the seal ring, the compression end cover and the compression nut sequentially from the interior of the water tank to the outside. The cylindrical external thread part is arranged in the mounting hole, the end, located in the water tank, of the external thread part is provided with a protrusion, and the other end of the external thread part is located outside the water tank. The two sides of the cylindrical wall of the water tank are clamped by the protrusion and the nut arranged on the external thread part. The cylindrical compression nut is in threaded connection with the external thread part and enables the compression end cover, the seal ring and the external thread part to be connected in an abutting mode. The compression end cover is fixedly arranged on the guide tube, and the compression cover and the outer circle of the guide tube are sealed. The sealing structure has the advantages of being simple in mounting technology, convenient to inspect and maintain, capable of prolonging the service life of the water tank and the like.
Description
Technical field
The present invention relates to a kind of sealing configuration, particularly relate to a kind of sealing configuration of the water tank for heat pump water heater.
Background technique
Working life and the water tank of current heat pump water heater have direct relation, the working life of water tank except having relation with water quality, also and the Placement of external equipment and water tank have direct relation; The water tank of sealing all needs water intake, water outlet, instrument mount inlet etc., the equipment that these perforates are installed is all generally welding box body that is direct and water tank, casing can be subject to the impact of high temperature in the process of welding, steel microstructure near weld seam changes, corrosion resistance reduces, therefore weld joint comparatively easily by aqueous corrosion, which reduces the working life of water tank in all the other positions; Be welded on equipment also not easy-maintaining and the replacing on water tank in addition, under some conditions, also not easily implement welding technology.
Summary of the invention
The present invention is intended to solve above-mentioned mentioned technical problem, provides the sealing configuration that a kind of technique is simple, easy for installation.
The present invention is realized by following technological scheme:
A kind of sealing configuration, comprises conduit and connected element, makes inner chamber and the ft connection of water tank in the mounting hole that tubular conduit is arranged at water tank; Connected element comprises external thread part, nut, seal ring, compression end cap and gland nut; On conduit, external thread part, seal ring, compression end cap and gland nut is set with outwardly successively by water tank, the external thread part of tubular is arranged in mounting hole, the one end being positioned at water tank is provided with projection, the other end is positioned at the outside of water tank, protruding and the nut clip be arranged on external thread part is located at the both sides of water tank barrel, the gland nut of tubular is threaded with external thread part and compression end cap, seal ring is abutted with external thread part three, and compression end cap is installed on conduit and with the cylindrical of conduit and seals.
Further, described compression end cap and the outer rim of conduit use circumferential weld or bonding mode to seal.
Further, described external thread part is provided with the cavity volume holding seal ring and compress end cap.
Further, described seal ring is several circular packing compositions.
Further, rubber sheet gasket is folded with between described projection and the inwall of water tank.
Beneficial effect is: a kind of sealing configuration of the present invention, and use is threaded, and without the need to using the mode of welding to be welded on water tank by equipment, it is convenient to implement; Use is threaded, and can not cause damage to water tank, extends the working life of water tank; Meanwhile, be threaded also easily inspection and maintenance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Fig. 1 is the schematic diagram of a kind of sealing configuration in the present invention;
Fig. 2 is the explosive view of connected element in Fig. 1.
Embodiment
A kind of sealing configuration as Figure 1-Figure 2, is applicable to the water tank 1 of heat pump water heater and the sealing of external apparatus interface.
Sealing configuration comprises conduit 2 and connected element, makes inner chamber and the ft connection of water tank 1 in the mounting hole that tubular conduit 2 is arranged at water tank 1; Connected element comprises external thread part 3, nut 4, seal ring 5, compresses end cap 6 and gland nut 7; On conduit 2, by being set with external thread part 3, seal ring 5 in water tank 1 outwardly successively, compressing end cap 6 and gland nut 7, the external thread part 3 of tubular is arranged in mounting hole, the one end being positioned at water tank 1 is provided with protruding 31, the other end is positioned at the outside of water tank 1, protruding 31 are folded in the both sides of water tank 1 barrel with the nut 4 be arranged on external thread part 3, the gland nut 7 of tubular be threaded with external thread part 3 and make compression end cap 6, seal ring 5 abuts with external thread part 3 three, compress end cap solid 6 and be located on conduit 2 and with the cylindrical of conduit 2 and seal.Be arranged between gland nut 7 and external thread part 3 owing to compressing end cap 6, the conduit 2 fixing with compressing end cap 6 can not be come off from water tank 1; Under the effect of gland nut 7, compress end cap 6 and seal ring 5 is compressed and makes it distortion, thus make the axial seal of conduit 2, prevent the medium in water tank 1 from leaking between conduit 2 and external thread part 3.
Described compression end cap 6 and the outer rim of conduit 2 use circumferential weld or bonding mode to seal.Compress end cap 6 and need that there is certain intensity with the sealing of conduit 2, when to avoid on conduit 2 erection unit or be collided, compress end cap 6 and depart from conduit 2, thus conduit 2 is departed from from water tank 1.
Described external thread part 3 is provided with the cavity volume 32 holding seal ring 5 and compress end cap 6.Use cavity volume 32 can make seal ring 5 centering more accurately, avoid seal ring 5 bias to cause the medium in water tank 1 to be revealed.
Described seal ring 5 is several circular packing compositions.Seal ring 5 is superimposed together by multiple packing and makes, and sealing effect is better; As revealed at seal ring 5 place, gland nut 7 can be tightened, making to compress end cap 6 pairs of seal rings 5 and applying larger pressure, thus increasing the sealing effect of seal ring 5.
In order to prevent medium from leaking between protruding 31 and the inwall of water tank 1, between described protruding 31 and the inwall of water tank 1, be folded with rubber sheet gasket.
Above embodiment is only not limited in order to technological scheme of the present invention to be described, all do not depart from spirit and scope of the invention any amendment or equivalently to replace, it all should be encompassed in the scope of technical solution of the present invention.
