Pneumatic blow-off valve of air-blower closes valve device in, connect compressed air source by the trunk line, supplement the inside not enough phenomenon of atmospheric pressure of trunk line through this compressed air source, solve when the trunk line atmospheric pressure is insufficient to cause pneumatic blow-off valve to close the difficult problem, guarantee equipment normal use function, and then guarantee that production goes on smoothly.
Description
Technical Field
The utility model belongs to air-blower application especially relates to air-blower pneumatic blow-off valve closes valve gear.
Background
The existing pneumatic air release valve of the air blower is simple and convenient to apply on site, the valve opening speed is high when the air blower fails, and the air release pneumatic valve is closed and opened by utilizing the pipeline pressure of the air blower through the control of an electromagnetic valve. In practical application, if main pipeline pressure is low or just can't close the atmospheric valve when sweeping the main pipeline, if the lower for example pressure value of pressure still can cause the indefinite phenomenon of one-way valve plate switching when making pneumatic valve action critical point in the main pipeline simultaneously, finally influences equipment normal use.
Disclosure of Invention
In view of this, the utility model aims at providing an air-blower pneumatic blow-off valve closes valve device to can normally close pneumatic blow-off valve when realizing that trunk line atmospheric pressure is lower.
In order to achieve the above purpose, the technical scheme of the utility model is realized like this:
the pneumatic blow-down valve of air-blower closes the valve gear, and the air-blower corresponds the setting on the trunk line of equipment, and the setting of pneumatic blow-down valve is at the trunk line inlet end, and this trunk line has connect an auxiliary line by pneumatic blow-down valve inlet end position department, and this auxiliary line is external to have compressed air source.
Furthermore, the auxiliary pipeline and the air blower are communicated with the main pipeline through two inlet and one outlet three-way valves, and the auxiliary pipeline and the air blower are respectively communicated with one inlet of the two inlet and one outlet three-way valves.
Furthermore, a pressure reducing valve is installed on the auxiliary pipeline.
Further, the gas pressure at the outlet end of the auxiliary pipeline is 25-35 kp.
Further, the compressed air source is an air source generated by an air pump.
Compared with the prior art, the pneumatic blow-off valve of air-blower closes valve device have following advantage:
pneumatic blow-off valve of air-blower closes valve device in, connect compressed air source by the trunk line, supplement the inside not enough phenomenon of atmospheric pressure of trunk line through this compressed air source, solve when the trunk line atmospheric pressure is insufficient to cause pneumatic blow-off valve to close the difficult problem, guarantee equipment normal use function, and then guarantee that production goes on smoothly.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in figure 1, the air blower pneumatic air release valve closing device is characterized in that an air blower 1 is correspondingly arranged on a main pipeline 2 of equipment 8, a pneumatic air release valve 3 is arranged at the air inlet end of the main pipeline 2, an auxiliary pipeline 7 is connected to the main pipeline 2 beside the air inlet end of the pneumatic air release valve 3, and a compressed air source is connected to the auxiliary pipeline 7 externally. In this embodiment, the compressed air source produces the air supply for air pump 6, for implementing the gas pressure in the detection pipeline, for obtaining the 3 gas pressure that get into pneumatic blow-off valve, this trunk line is equipped with pressure sensor near 3 inlet end positions of pneumatic blow-off valve, and this pressure sensor and controller electricity are connected, auxiliary conduit 7 and air-blower 1 are through two one-in-one-out three-way valves 4 and trunk line 2 intercommunication, and auxiliary conduit 7 and air-blower 1 are respectively with 4 import intercommunications of these two one-in-one-out three-way valves. Through the pressure sensor detection gas pressure of 3 import positions departments of pneumatic blow-down valve, when needing to close pneumatic blow-down valve 3, if this position department pressure sensor detection gas pressure value is less than critical atmospheric pressure, then auxiliary line 7 and trunk line 2 intercommunication, compressed air source get into trunk line 2 and increased the trunk line internal pressure, and then close pneumatic blow-down valve 3. If the pressure in the main pipeline is gradually increased to the set pressure, the two-in one-out three-way valve 4 is switched to the state of only supplying air by the blower.
In this embodiment, the auxiliary pipe 7 is provided with a pressure reducing valve 5. The gas pressure of the auxiliary pipeline 7 entering the pneumatic emptying valve 3 is 25-35 kp.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
