Abstract
The utility model relates to a liquid dirt discharge outlet apparatus, the working condition of which has vacuum in a refrigeration machine body. The utility model is composed of a thread fastening cover (1), a dirt discharge outlet seat (2) with outer threads, a sealed pad (3) and a sealed pressing block (4). Due to the adoption of the mode of indirectly extruding the sealed pad (3) without direct friction of the sealed pad (3), the sealed pad (3) can not be worn out to deform. The utility model has good sealed effect and is capable of ensuring favorable vacuum degree environment of refrigeration machines.
Description
It is the liquid sewage mouth device of vacuum that the utility model relates to the interior working environment of a kind of refrigerator body.
At present, lithium-bromide absorption-type refrigerating machine is generally taked to add a rubber washer at sewage draining exit place end face at the sewage draining exit of removing inner dirt, and the threaded plug plug of apparatus is blocked outlet and screwed.The shortcoming of this practice is: in the process that plug screws, two end faces up and down of packing ring are rubbed, and are fragile, are difficult to ensure the vacuum environment in the refrigerator body.
The purpose of this utility model provides a kind of sealing gasket and is not rubbed, and guarantees the impregnable blowdown apparatus of vacuum in the refrigeration machine machine.
Design of the present utility model is: it is made up of screw threads for fastening lid, band external screw thread sewage draining exit seat, sealing gasket, sealed briquette, it is characterized in that, band external screw thread sewage draining exit seat oral area has a pair of " ┌ ┐ " shape briquetting claw hook in opposite directions near the edge, it and sewage draining exit seat are integral, and a pair of briquetting claw hook forms the briquetting gathering sill with band external screw thread sewage draining exit seat mouth end face; There is a positive even numbers side plate piece at middle part, screw threads for fastening lid outer face, is integral with the screw threads for fastening lid; The sealed briquette cross section is " protruding " shape.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is the generalized section of facing of prior art blowdown plug;
Fig. 2 faces generalized section for the utility model;
Fig. 3 takes off the vertical view of screw threads for fastening lid for the utility model.
Above-mentioned as in, 1-screw threads for fastening lid, 2-band external screw thread sewage draining exit seat, the 3-sealing gasket, the 4-sealed briquette, 5-briquetting claw hook, 6-briquetting gathering sill, the 7-plate, 8-stops up, 9-packing ring, 10-sewage draining exit seat.
Embodiment 1:
The utility model is made up of screw threads for fastening lid (1), band external screw thread sewage draining exit seat (2), sealing gasket (3), sealed briquette (4), it is characterized in that with near external screw thread sewage draining exit seat (2) mouthful edge a pair of " ┌ ┐ " shape briquetting claw hook (5) in opposite directions being arranged, it is integral with band external screw thread sewage draining exit seat (2), and a pair of pressing plate claw hook (5) forms briquetting gathering sill (6) with band external screw thread sewage draining exit seat (2) mouthful end face; There is a regular hexagon plate (7) at middle part, screw threads for fastening lid (1) outer face, is integral with screw threads for fastening lid (1); Sealed briquette (4) cross section is " protruding " shape; Sealing gasket (3) is greater than the flexible plastics king disk of being with of sewage draining exit seat internal diameter.
Assembling process of the present utility model is: will be with external screw thread sewage draining exit seat (2) base port to aim at the sewage draining exit seat, be welded into the seam of no leak source, to be with flexible plastics king disk sealing gasket (3) along briquetting gathering sill (6), to seal with the oral area of external screw thread sewage draining exit seat (2), the large end face of sealed briquette (4) contacts with being with flexible plastics king disk sealing gasket (3), place in the briquetting gathering sill (6), sealed briquette after putting into (4) has a fixed gap with briquetting claw hook (5), sealed briquette (4) small end face is higher than briquetting claw hook (5) upper surface, the screw threads for fastening of screwing on lid (1), its internal thread is connected mutually with external screw thread with externally threaded sewage draining exit seat (2), uses spanner clamping plate (7) to tighten at last.
Embodiment 2:
It all is the disk of rubber that sealing gasket of the present utility model (3) also can make both ends of the surface; The plate (7) at middle part, screw threads for fastening lid (1) outer face can adopt square or octagon.Other are with embodiment 1.
Embodiment 3:
The one side of sealing gasket of the present utility model (3) is that rubber or outer shroud are rubber, and other are with embodiment 1.
The utility model is because employing has friction with sealed briquette (4), and the mode of crush seal pad (3) without direct friction sealing gasket (3), makes sealing gasket (3) not suffer abrasion deformation, and good sealing effect can ensure the vacuum environment that refrigeration machine is good.
Claims (4)
1, a kind of screw threads for fastening end face does not have friction sealed blowdown apparatus, it is characterized in that it is made up of screw threads for fastening lid (1), band external screw thread sewage draining exit seat (2), sealing gasket (3), sealed briquette (4):
A, band external screw thread sewage draining exit seat (2) have a pair of " ┎ ┒ " shape briquetting claw hook in opposite directions near the oral area edge, it is integral with band external screw thread sewage draining exit seat (2), and a pair of briquetting claw hook (5) forms briquetting gathering sill (6) with band external screw thread sewage draining exit seat (2) mouthful end face;
There is a positive even numbers side plate piece (7) at B, middle part, screw threads for fastening lid (1) outer face, are integral with screw threads for fastening lid (1);
C, sealed briquette cross section are " protruding " shape.
2, screw threads for fastening end face according to claim 1 does not have friction sealed blowdown apparatus, it is characterized in that sealing gasket (3) is for being with flexible plastics king disk;
3, screw threads for fastening end face according to claim 1 does not have friction sealed blowdown apparatus, it is characterized in that sealing gasket (3) has at least one side to be rubber face;
4, screw threads for fastening end face according to claim 1 does not have friction sealed blowdown apparatus, it is characterized in that an outer shroud of sealing gasket (3) is a rubber.
