It states gas off-take and is connected with escape pipe, first epithelium healing is connected with low-pressure meter, and second epithelium healing is connected with high pressure gauge, institute
Air flue is connected with pressure regulating device before stating, and is provided with sealing structure between the pressure regulating device and the preceding air flue,
Further include shell, the shell includes upper housing and lower case, the valve body setting the upper housing with it is described
In the cavity formed after lower case engaging.
Optional: the sealing structure includes upper seal and lower seal, and the upper seal bottom setting is fluted,
The lower seal top is provided with boss, gasket is additionally provided between the upper seal and the lower seal, under described
Seal boss be inserted into the groove of the upper seal by the gasket be fixed on the upper seal and the lower seal it
Between.
Optional: the upper seal and lower seal are rubber material.
Optional: the end of the air intake duct is provided with filter.
Optional: the pressure regulating device includes pressure regulation handle.
Optional: the upper housing and the lower case are transparent PE material.
By adopting the above technical scheme, due to being provided with the upper housing and lower case of engaging outside pressure reducer, can will subtract
Depressor protects, and is provided with sealing structure, not only increases the shatter-resistant performance of pressure reducer, also improves the longevity of pressure reducer
Life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model shatter-resistant gas pressure reducer；
Fig. 2 is the cross-sectional view of sealing structure in the utility model shatter-resistant gas pressure reducer.
In figure, 1- valve body, 2- gas off-take, the first epithelium healing of 3-, the second epithelium healing of 4-, 5- air intake duct, 6- low-pressure meter, 7- high
Press table, 8- air inlet nut, 9- pressure regulating device, 10- shell, 11- upper seal, 12- lower seal, 13- gasket.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
A kind of shatter-resistant gas pressure reducer is respectively arranged with gas off-take 2, air inlet on valve body 1 as shown in Figure 1, including valve body 1
Road 5, the first epithelium healing 3, the second epithelium healing 4 and preceding air flue, air intake duct 5, the first epithelium healing 3, the second epithelium healing 4 and preceding air flue phase
Logical, air intake duct 5 is connected with air inlet pipe by air inlet nut 8, and sealing structure, outlet are provided between air inlet nut 8 and air inlet pipe
Road 2 is connected with escape pipe, and the first epithelium healing 3 is connected with low-pressure meter 6, and the second epithelium healing 4 is connected with high pressure gauge 7, preceding air flue connection
