Abstract
The utility model relates to a refrigerant joint, which can mainly solve the problem that the prior refrigerant joint will generate leakage. The utility model is characterized in that: a joint body(1) is provided with a fork-shaped branch pipe(3) which is communicated with a cavity(2)of the joint body; the cavity(2) is provided with a thimble(4) inside; a gland cover(7) is arranged between the upper tip(5) of the joint body(1) and the thimble(4), and the gland cover is pressed by a prepared cap(6). The utility model has the advantages that: the leakage will not be generated; the sealing effect is good and the operation is simple.
Description
Technical field:
The utility model relates to interpolation refrigerant accessory used on the chilling unit, belongs to a kind of refrigerant joint that adds.
Background technology:
In daily life and producing, chilling unit is used widely, chilling unit comprises air-conditioning, refrigerator, refrigerator-freezer etc., and the refrigeration processes of these equipment all to be circulation by refrigerant realize, when chilling unit needs to add refrigerant after long-term the use, convenient in order to add refrigerant, refrigerant circulating system all has plunger tip formula check valve mostly at present, can back down spool and add refrigerant in system, used joint is built-in fixedly thimble, when adding refrigerant, because it is gapped between the screw thread of joint, cause refrigerant to leak, and then cause waste and environmental pollution, also easy simultaneously frostbite operating personnel.
The utility model content:
Produce the deficiency of leaking in order to overcome the existing refrigerant joint that adds, the utility model provides a kind of refrigerant joint that adds, and this adds the refrigerant joint and has the leakage of not producing, good sealing effect and characteristics easy and simple to handle.
The technical solution of the utility model is: this adds the refrigerant joint and comprises fittings body, has " fork " shape arm that communicates with its inner chamber on the fittings body, and inner chamber is built-in with thimble, is equipped with between the upper end of fittings body and the thimble to be equipped with the sealing shroud that cap compresses.
Have Ka Tai on the above-mentioned thimble.
The utlity model has following beneficial effect: owing to having " fork " shape arm that communicates with its inner chamber on the fittings body of taking in the such scheme, inner chamber is built-in with thimble, when the jointing body, the available thimble of having handed up disengages thimble and plunger tip formula check valve, connects the pin that bears down on one behind the plunger tip formula check valve downwards, make it back down plunger tip formula check valve, exist the gap that refrigerant is leaked between can be in this process because of screw thread, easy and simple to handle, good sealing effect.
Description of drawings:
Accompanying drawing 1 is a structure cutaway view of the present utility model.
1-fittings body among the figure, the 2-inner chamber, the 3-arm, the 4-thimble, the 5-upper end, 6-is equipped with cap, 7-sealing shroud, 8-Ka Tai.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:.
As shown in Figure 1, this adds the refrigerant joint and comprises fittings body 1, has " fork " shape arm 3 that communicates with its inner chamber 2 on the fittings body 1, and inner chamber 2 is built-in with thimble 4, thimble 4 can slide up and down, have card platform 8 on the thimble 4,8 spacing and guide effects of card platform have the space between thimble 4 and the inner chamber 2, being convenient to refrigerant passes through, when jointing body 1, the available thimble 4 of having handed up disengages thimble 4 and plunger tip formula check valve; Be equipped with the sealing shroud 7 that cap 6 fully compresses between the upper end 5 of fittings body 1 and the thimble 4, connect the pin 4 that bears down on one behind the plunger tip formula check valve downwards, make it back down plunger tip formula check valve, exist the gap that refrigerant is leaked between can be in this process because of screw thread.
This shows that this adds the refrigerant joint and has the leakage of not producing, good sealing effect and behaviour Make easy characteristics, be worth of widely use.
Claims (2)
