Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
Anti-dropout radial direction double containment in the present embodiment plug assembly that discharges water consists of three parts, including the plug body 1 that discharges water, set
The drain plug pedestal 3 of sealing ring 2 and tubulose in the plug body 1 that discharges water, wherein the side wall of drain plug pedestal 3 is equipped with and leads
Discharge orifice 31, the plug body that discharges water 1 is inserted into drain plug pedestal 3 and sealing ring 2 thereon is located at the deflector hole 31 of drain plug pedestal 3
Top is connected between the plug body that discharges water 1 and drain plug pedestal 3 by being correspondingly arranged at the thread segment on top, the plug body that discharges water 1
Lower part is equipped with resilient clip 11, and resilient clip 11 stretches out the lower end surface of drain plug pedestal 3 and drain plug pedestal 3 for resilient clip 11
12 barrier of boss of end point is outside.
The modular construction changes the structure type for the plug body 1 that discharges water, and increases the drain plug pedestal 3 with deflector hole 31,
And mutually inserting cooperation, the resilient clip 11 with boss 12 by the way that 1 bottom of plug body that discharges water is arranged in discharge water between the two
Plug body 1 can be mobile relative to drain plug pedestal 3, and will not completely disengage drain plug pedestal 3, when effectively preventing putting coolant liquid
The occurrence of displacement of the plug body that discharges water 1 is fallen.When installing and using, the drain plug pedestal 3 added both can be straight with water tank chamber
It connects and is integrated into integrated, can also be used as a separate piece, connected by sebific duct, anchor ear etc. with water tank chamber, and simplify
Installation difficulty and manufacture difficulty.
In the plug body 1 that discharges water in the present embodiment in the axial direction from top to bottom include thread segment 1a, seal section 1b and
Resilient clip 11, wherein thread segment 1a outer diameter is greater than seal section 1b outer diameter and 11 outer diameter of resilient clip, seals when to avoid installation
Section 1b or resilient clip 11 damage the internal screw thread 3a of drain plug pedestal.The plug body 1 that discharges water herein is equivalent to multi-diameter shaft, corresponding
, the centre bore of tubulose drain plug pedestal 3 is the stepped hole matched with the plug body 1 that discharges water.
In the present embodiment, there are two sealing rings 2 and interval setting, one of sealing ring are always positioned at drain plug pedestal 3
The top of deflector hole 31, and another sealing ring (i.e. buckling state) when the plug body 1 that discharges water blocks drain plug pedestal 3 is located at
31 lower section of deflector hole；At this point, there are sealing ring in about 31 two sides of deflector hole of drain plug pedestal 3, closure process is effectively prevented
Leakage problems in (buckling state) at deflector hole screw thread；And during coolant drain, that above pulls out discharges water in plug body 1
Two sealing rings are respectively positioned on 31 top of deflector hole, further ensure the sealing performance of hand of spiral, while making discharge process
Middle coolant liquid can only be flowed out by deflector hole.Certainly, the quantity of sealing ring is not limited to two herein, can also there is multiple, cloth
As long as meeting the sealing to junction between deflector hole and drain plug pedestal 3 and the plug body 1 that discharges water in office.
In the present embodiment, the top of the plug body that discharges water 1 is equipped with handle 13.Handle 13 can meet singlehanded attaching/detaching and discharge water
The operational requirements of plug body simplify operation complexity without using professional tool.
Resilient clip 11 in the present embodiment is tool there are two the U-shaped card of supporting leg, and boss 12 sets up separately the two of U-shaped card
Supporting leg end outside.Resilient clip 11 herein can be an integral structure with thread segment 1a, seal section 1b, can also be independent
Part is connect by connector with the plug body 1 that discharges water integral.There is gap, when putting between 3 inner hole of two supporting legs and drain plug pedestal
When water plug body 1 lifts, coolant liquid flow to deflector hole 31 by gap.
As a further improvement of the foregoing solution, through slot is offered on two supporting legs of U-shaped card.Both having reduced raw material makes
Dosage has saved cost, at the same also increase coolant liquid by area, be conducive to shorten drain time.
In the present embodiment, boss 12 and supporting leg in U-shaped card constitute placed arrow type structure, smoothed between boss 12 and supporting leg
It crosses.Elastic u-shaped clamp front end projection section is no acute angle rugby contoured design, the supporting leg flowing transition with rear, both
Interference of the plug body 1 to water tank internal flow that discharge water is reduced, fluid is avoided and forms vortex and reduce water tank heat exchange or water
The problem of transition of stress concentration in box part position leads to leakage；Facilitate the lossless assembly manipulation and drain plug of sealing ring 2 again simultaneously
The subsequent taking-up demand when necessary of ontology 1.
As a further improvement of the foregoing solution, the seal section 1b of the plug body that discharges water 1 is equipped with the ring of embedding sealing circle 2
Slot, convenient for the assembly and positioning of sealing ring 2.
When design, the length of resilient clip, the position of boss, size, the distance between resilient clip and Double seal ring are put
Water plug pedestal water conservancy diversion hole site and size, screw thread segment length etc. will carry out matched design, to guarantee to open the plug body discharge that discharges water
The problem of leaking elsewhere does not occur when coolant liquid.
The plug assembly that discharges water be mounted and taken out operation it is as follows:
Installation operation: one hand holds the plug body upper handle that discharges water for having sealing ring, by the front end (elasticity for the plug body that discharges water
Clamp) the alignment drain plug pedestal hole internal screw thread 3a center, slowly insertion is internal, rotating handle to closure position.
Coolant drain operation: it rotates plug body upper handle to the resilient clip convex platform that discharges water and blocks drain plug pedestal lower end
Stop behind face, the position for two in the plug body sealing rings that discharge water at this time is moved to drain plug from drain plug pedestal deflector hole two sides
Pedestal deflector hole top, the seal section 1b of the plug body that discharges water 1 and sealing ring thereon are stepped down, and deflector hole is against resilient clip, water
Coolant liquid inside case can be flowed out outside water tank by deflector hole；When reverse rotation discharges water plug body until two sealing rings point
Not Wei Yu deflector hole two sides, then sealing ring cut off coolant liquid, discharge stop.
Take out operation: the handle that rotation discharges water in plug body, when resilient clip projection section blocks drain plug pedestal lower end
Behind face, after continuing firmly to rotate boss being made to enter drain plug pedestal internal channel (centre bore), continue to be rotated up taking-up discharging water
Until plug body.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
