Abstract
The utility model discloses a dispenser. The dispenser comprises a main joint (1) and a shower nozzle (2) which is fixed to the main joint (1), wherein a main pipeline (3) is arranged in the main joint (1), a plurality of branch pipelines (4) are arranged on the shower nozzle (2), the branch pipelines (4) are communicated with the main pipeline (3), and at least one layer of a filtering net (5) is arranged in the main pipeline (3). By the aid of the dispenser, the production efficiency is improved, the production cost is reduced, welding points of construction are reduced and the leakage of the refrigerant is avoided.
Description
Technical field
The utility model relates to field of air conditioning, specifically is a kind of knockout.
Background technology
Heat exchanger (comprising indoor heat exchanger and outdoor heat exchanger) in air-conditioning system is provided with knockout, and the effect of this knockout is that one refrigerant with refrigerant pipe is evenly distributed in each heat exchange coil of heat exchanger to ensure the effect of refrigerant heat exchange.The heat exchanger of prior art comprises a major joint and a shower nozzle of fixing with major joint, be provided with one in the major joint for the trunk line that is communicated with refrigerant pipe, be provided with in the shower nozzle a plurality of radially distribute be used for the branch pipe(tube) is communicated with each heat exchange coil, trunk line is communicated with whole branch pipe(tube)s.For guaranteeing that refrigerant normally circulates, prevent from stopping up, in air-conditioning system, also be provided with filter.
For guaranteeing shunting and the filtration of refrigerant, just must develop knockout and two kinds of moulds of filter and produce this two kinds of parts, therefore reduced production efficiency, increased production cost, and, necessary erection welding knockout and filter in air-conditioning system, the pad of construction is many, and the hidden danger of refrigrant leakage increases.
Summary of the invention
The technical problems to be solved in the utility model is that the knockout of a kind of pad that can enhance productivity, reduce production costs, reduce construction, reduction refrigrant leakage hidden danger is provided.
Technical solution of the present utility model is, a kind of knockout with following structure is provided, it comprises major joint and the shower nozzle of fixing with major joint, be provided with a trunk line in the major joint, shower nozzle is provided with a plurality of branch pipe(tube)s, all branch pipe(tube) all is communicated with trunk line, is provided with at least one metafiltration net in the trunk line.
After adopting above structure, the utility model knockout compared with prior art has following significant advantage and technique effect:
Owing to being provided with at least one metafiltration net in the trunk line, like this, the trunk line of major joint is communicated with refrigerant pipe and every branch pipe(tube) of shower nozzle is communicated with a heat exchange coil of heat exchanger, this knockout has not only kept the traditional function of refrigerant separatory, and had the filtration refrigerant of filter concurrently, prevent the function of blocking, only need mold and produce this a kind of knockout and need not to make in addition filter, therefore improved production efficiency, reduced production cost, and, only need a kind of part of this knockout of welding in the air-conditioning system, reduce the construction pad, reduced the hidden danger of refrigrant leakage.
As improvement, trunk line is made of two different duct sections of bore, two duct sections are communicated with and connectivity part is step surface, and filter screen is circular filter screen, and the diameter of filter screen is greater than the bore of the little duct section of bore, and the diameter of filter screen equals the bore of the large duct section of bore, like this, filter screen is put into the large duct section of bore, then refrigerant pipe is inserted this duct section, filter screen is pushed against on the step surface between two duct sections by refrigerant pipe, and this Standard is convenient, firmly.
As improving, the inside pipe wall of the outer end of the duct section that bore is large is provided with a circle chamfering, is convenient to so the large duct section of refrigerant pipe interference fit Inserting Tube internal diameter again.
As also improving, the large 2mm of bore of the duct section that the bore of the duct section that bore is large is less than bore, this size is easily manufactured and be convenient to being mounted with of filter screen.
Description of drawings
Fig. 1 is that the half section of the utility model knockout is faced structural representation.
As shown in the figure 1, major joint, 2, shower nozzle, 3, trunk line, 3.1, duct section that bore is large, 3.2, duct section that bore is little, 4, branch pipe(tube), 5, filter screen, 6, step surface, 7, chamfering.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model knockout, it comprises major joint 1 and the shower nozzle 2 of fixing with major joint 1.Be provided with one in the major joint 1 for the trunk line 3 that is communicated with refrigerant pipe, shower nozzle 2 is provided with a plurality of branch pipe(tube)s 4 that are communicated with each heat exchange coil that radially distribute.All branch pipe(tube) 4 all is communicated with trunk line 3.Be provided with at least one metafiltration net 5 in the trunk line 3.Trunk line 3 is made of two different duct sections of bore, two duct sections are communicated with and connectivity part is step surface 6, filter screen 5 is circular filter screen 5, and the diameter of filter screen 5 is greater than the bore of the little duct section 3.2 of bore, and the diameter of filter screen 5 equals the bore of the large duct section of bore 3.1.The large 2mm of bore of the duct section 3.2 that the bore of the duct section 3.1 that bore is large is less than bore.The inside pipe wall of the outer end of the duct section 3.1 that bore is large is provided with a circle chamfering 7.
Claims (4)
1. knockout, it comprises major joint (1) and the shower nozzle (2) of fixing with major joint (1), be provided with a trunk line (3) in the major joint (1), shower nozzle (2) is provided with a plurality of branch pipe(tube)s (4), all branch pipe(tube) (4) all is communicated with trunk line (3), it is characterized in that: be provided with at least one metafiltration net (5) in the trunk line (3).
