Abstract
The utility model discloses a refrigeration check valve, including valve body, import copper pipe and export copper pipe, export copper guan weiyi head diameter is greater than the copper pipe of body portion diameter, and the head of export copper pipe is brazed fixedly with the exit end of valve body. The utility model has the advantages that adopt brazing of red copper and brass, avoided the complicated technology of brass and copper bond to the urosome has saved, and it is with low costs, the structure is simplified, and spare part is than less, and welding quality is good, and intensity is high, and manufacturing is convenient, simple process, and the dependable performance, long service life, economic nature is good.
Description
Technical field
The utility model relates to a kind of valve means, particularly one refrigeration one-way valve.
Background technique
In prior art, because individual event valve inside will load necessary part, first import and export copper pipe is welded on brass body and brass urosome so have employed, again brass body and brass urosome is welded after then loading inner body.Deficiency is: the welding process requirement of brass and brass is higher, adds and will prevent one-way valve inner body from crossing cause thermal damage, and welding quality is difficult to ensure.Also need to weld for three times, soldering part requirement on machining accuracy is high, thus causes high cost.
In view of above-mentioned technical problem, need to provide a kind of novel one-way valve, it can avoid the welding between brass, reduces the technological requirement to welding, improves soldering reliability, reduces costs.
Model utility content
Technical problem to be solved in the utility model to provide a kind of cost low, improves the refrigeration one-way valve of valve body reliability.
In order to solve above technical problem, the utility model provides a kind of refrigeration one-way valve, comprise valve body, import copper pipe and outlet copper pipe, described outlet copper pipe is the copper pipe that a head diameter is greater than body portion diameter, and the outlet head of copper pipe and the outlet end soldering of valve body are fixed.
Described outlet copper pipe is red copper.
Described valve body is built with piston, piston guide assembly and Returnning spring, and Returnning spring is placed on piston, and piston guide assembly is positioned at piston cavity.
The enlarging head of the outlet copper pipe of described valve body replaces brass urosome, soldering direct with valve body.Valve body entrance point soldering import copper pipe, after part all loads in valve body, is then directly soldered to the outlet end of valve body by the head of outlet copper pipe.
Superior effect of the present utility model is:
1) the utility model adopts the soldering of red copper and brass, and avoid the complicated technology of brass and brass welding, and eliminate urosome, cost is low;
2) the utility model structure is simplified, and component are fewer, and welding quality is good, and intensity is high, convenient processing and manufacture, and technique is simple, reliable performance, long service life, good economy performance.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the structural representation of the utility model embodiment forward conduction, and Fig. 2 shows the structural representation that the utility model embodiment oppositely ends.As depicted in figs. 1 and 2, the utility model provides a kind of refrigeration one-way valve, comprise valve body 2, import copper pipe 1 and outlet copper pipe 5, described outlet copper pipe 5 is the copper pipe that head 501 diameter is greater than body portion 502 diameter, and the head 501 of outlet copper pipe 5 is fixed with the outlet end soldering of valve body 2.
Described outlet copper pipe 5 is red copper.
Described valve body 2 is built with piston 3, piston guide assembly 4 and Returnning spring 5, and Returnning spring 5 is placed on piston 3, and piston guide assembly 4 is positioned at piston cavity.
The utility model refrigeration one-way valve can be used on the liquid of refrigeration and the air bells conditioner adopting fluoride refrigeration agent, air-breathing and hot gas line.
As shown in Figure 1, when the inlet pressure of refrigeration one-way valve is higher than outlet pressure, and when the active force that pressure reduction causes is greater than Returnning spring 6 power, piston 3 is pushed to right by difference force along outlet passage.The restriction that piston 3 is subject to piston guide assembly 4 is linearly moved to the right, and Returnning spring 6 is compressed simultaneously.Fluid flows through refrigeration one-way valve, and refrigeration one-way valve is in forward conduction state.
As shown in Figure 2, when the outlet pressure of the one-way valve that freezes is greater than or equal to inlet pressure, under the active force acting in conjunction that return spring force and pressure reduction cause, piston 3 is pushed to left by along inlet passage.The restriction that piston 3 is subject to piston guide assembly 4 is linearly moved to the left, and piston 3 seals valve port.Fluid cannot by refrigeration one-way valve.Refrigeration one-way valve is in reverse blocking state.
The enlarging head 501 of the outlet copper pipe 5 of described valve body replaces brass urosome, with valve body 2 directly soldering.Valve body entrance point soldering import copper pipe 1, after part all loads in valve body, is then directly soldered to the outlet end of valve body 1 by the head 501 of outlet copper pipe 5.
The foregoing is only preferred embodiments of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. freeze an one-way valve, and comprise valve body, import copper pipe and outlet copper pipe, it is characterized in that: described outlet copper pipe is the copper pipe that a head diameter is greater than body portion diameter, the outlet head of copper pipe and the outlet end soldering of valve body are fixed; Described outlet copper pipe is red copper.
2. refrigeration one-way valve according to claim 1, is characterized in that: described valve body is built with piston, piston guide assembly and Returnning spring, and Returnning spring is placed on piston, and piston guide assembly is positioned at piston cavity.
