Detailed description of the invention
In order to be more clearly understood that the above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the accompanying drawings and
The present invention will be further described for embodiment.It should be noted that in the case of not conflicting, the application's
Feature in embodiment and embodiment can be mutually combined.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but, this
Bright can be different from other modes described here implement to use, therefore, the present invention is not limited to following
The restriction of the specific embodiment of prospectus.
Embodiment 1, as shown in Figure 1 and Figure 2, the invention provides a kind of diluted acid tank breather valve, including connection
Pipe 1, is mainly used in the acid & alkali liquid that circulates its communicating pipe 1, it is also possible to ventilating air, completes the positive and negative of breather valve
Pressure converts；One end in communicating pipe 1 is provided with the first housing 3, and the other end is provided with the second housing 2, and first
Housing 3 is mainly used in balancing the air pressure in breather valve, and the second housing 2 is mainly for delivery of liquid；First
The bottom of housing 3 is provided with air inlet 302, and the inside top at the first housing 3 is provided with the first receiving pipe
301, first accommodates in pipe 301 and is provided with the first valve body, and its air inlet 302, first accommodates pipe 301 and the
One valve body three defines a system in the first housing 3, mainly occurs that negative pressure is existing inside reply breather valve
As when, when i.e. the inside of breather valve is negative pressure appearance, the first valve body then can be away from air inlet 302
One accommodates operation in pipe 301, and the air of outside enters in breather valve, improves the air pressure within breather valve,
Inside and outside air pressure balance, breather valve is made normally to work；Second housing 2 inside bottom is provided with the second receiving pipe 204,
In the second gripper shoe 202 being provided above being arranged on the second housing 2 inwall accommodating pipe 204, support
It is provided with the second valve body on plate 202, between gripper shoe 202 and the second valve body, is provided with support set 203,
As in figure 2 it is shown, the second valve body is due to affected by gravity, for the good position fixing the second valve body,
It is provided with gripper shoe 202 and the support set 203 being arranged in gripper shoe 202；Arrange in receiving hole 201
