Abstract
The utility model provides an air valve with a filter screen, which is composed of an intake tube, a filter screen and a valve body and is characterized in that the filter screen is of a cavity structure with one end opened and is arranged between the intake tube and the valve body. Compared with the prior art, the air valve with a filter screen has the advantages of large filter area, long service time and no easy block.
Description
Technical field
The utility model relates to a kind of gas valve, particularly a kind of band filter screen air valve.
Background technology
Some gas equipments are when using gases; the impurity that usually can contain trace because of some gases; and cause the little hole plug of gas equipment; thereby influence result of use; so the air valve of band filter screen just occurred; existing band filter screen air valve comprises air inlet pipe, and filter screen and valve body, filter screen are a plane and the horizontal setting of air inlet pipe cross section.The maximum effective filtration area of this screen pack air valve has only air inlet pipe internal diameter cross section big, and the order number of filter screen is had relatively high expectations, thereby hinders gas communication, especially after using a period of time, filter screen stops up, and hinders gas communication especially greatly, influences the use of gas equipment.
The utility model content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, to provide filter area big, can use for a long time, not susceptible to plugging a kind of band filter screen air valve.
The technical solution of the utility model is: a kind of band filter screen air valve, comprise air inlet pipe, filter screen and valve body, and it is characterized in that filter screen is the cavity body structure of an end opening, filter screen is arranged between air inlet pipe and the valve body.
Described filter screen openend is when the valve body end is provided with, and the filter screen external diameter is less than the air inlet pipe internal diameter.
Described filter screen openend is when the air inlet pipe end is provided with, and the filter screen inner chamber is ccontaining foreign material chambeies.
It is big that the utility model compared with prior art has filter area, can use for a long time, not susceptible to plugging advantage.
Description of drawings
Fig. 1 is the utility model structure chart.
Concrete case study on implementation
The invention will be further described below in conjunction with accompanying drawing:
Shown in Figure 1, a kind of band filter screen air valve comprises air inlet pipe 1, filter screen 2 and valve body 3, and filter screen 2 is the cavity body structure of an end opening, and filter screen is arranged between air inlet pipe and the valve body.Described filter screen 2 openends are to valve body 3 end settings, and filter screen 2 external diameters are less than air inlet pipe 1 internal diameter.Described filter screen openend also can be provided with to the air inlet pipe end, and the filter screen inner chamber is ccontaining foreign material chambeies.
Claims (3)
1, a kind of band filter screen air valve comprises air inlet pipe, filter screen and valve body, it is characterized in that filter screen is the cavity body structure of an end opening, and filter screen is arranged between air inlet pipe and the valve body.
