Description
Technical Field
The utility model belongs to the technical field of the measuring equipment technique and specifically relates to indicate a measurement system discharge gate structure.
Background
The metering system is generally a weight metering device for industrial or trade large-scale objects, and refers to the matched use of modern electronic technologies such as program control, group control, telefax printing record, screen display and the like, so that the metering system has complete functions and higher efficiency. The metering system mainly comprises a bearing system (such as a scale pan and a scale body), a force transmission conversion system (such as a lever force transmission system and a sensor) and a value indicating system (such as a dial and an electronic display instrument) 3. In the combination of metering, production and sales, metering systems are receiving great attention, and the demand of the metering systems is increasing.
The discharge gate of title body only sets up a butterfly valve among present measurement system for the discharge gate receives to drag the influence with title body support easily, and receives the impact of air current, material and makes the measurement accuracy reduce. Therefore, there is a need to develop a solution to the above problems.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention is directed to the deficiency of the prior art, and the main objective of the present invention is to provide a discharge hole structure of a metering system, which can effectively solve the problem that the existing metering system is easily impacted by air flow and material, so that the metering accuracy is low.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a discharge port structure of a metering system comprises a scale body, a first butterfly valve and a second butterfly valve; the bottom of the scale body is provided with a first output port, the first butterfly valve is arranged at the first output port and communicated with the inside of the scale body, and the bottom of the first butterfly valve is provided with a second output port; the second butterfly valve is located under the first butterfly valve, an input port is formed in the top of the second butterfly valve, the whole periphery of the input port is in flexible connection with the whole periphery of the second output port through a ventilation hose, and a third output port is formed in the bottom of the second butterfly valve.
Preferably, the air-permeable hose is made of a needle felt material.
Preferably, the diameter of the second butterfly valve is larger than the diameter of the first butterfly valve.
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:
through being provided with first butterfly valve and second butterfly valve to the cooperation utilizes ventilative hose to carry out the flexible coupling with first butterfly valve and second butterfly valve, in order to eliminate the influence that the discharge gate title body support was dragged, and can control discharge gate below air current, the impact influence of the material impact symmetry body well, effectively promote the precision of measurement, and butterfly valve sealing performance is good, the gas tightness of the control title body that can be fine, further promote measurement accuracy, facilitate for the use.
To more clearly illustrate the structural features and functions of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

Detailed Description
Referring to fig. 1, a specific structure of a preferred embodiment of the present invention is shown, which includes a scale body 10, a first butterfly valve 20 and a second butterfly valve 30.
The bottom of the scale body 10 is provided with a first output port 11, the first butterfly valve 20 is arranged at the first output port 11 and communicated with the inside of the scale body 10, and the bottom of the first butterfly valve 20 is provided with a second output port 21.
The second butterfly valve 30 is located right below the first butterfly valve 20, the top of the second butterfly valve 30 has an input port 31, the entire periphery of the input port 31 is flexibly connected to the entire periphery of the second output port 21 through a ventilation hose 40, and the bottom of the second butterfly valve 30 has a third output port 32. In this embodiment, the diameter of the second butterfly valve 30 is larger than the diameter of the first butterfly valve 20, so as to eliminate the influence of the misalignment between the second butterfly valve 30 and the first butterfly valve 20 on the material accumulation and material leakage, and the air permeable hose 40 is made of needle felt.
Detailed description the working principle of the present embodiment is as follows:
during the measurement, before the material got into the balance body 10, make first butterfly valve 20 open, second butterfly valve 30 closes, then, make the material get into in the balance body 10, the air current of discharge gate below has been controlled well, the impact influence of symmetry bodies 10 such as material impact, promote the precision of measurement, during the measurement, close first butterfly valve 20, and make second butterfly valve 30 open, after the measurement is accomplished, open first butterfly valve 20 again, the material in the balance body 10 can be through first butterfly valve 20, ventilative hose 40 and the output of second butterfly valve 30 in order to accomplish the ejection of compact.
The utility model discloses a design key is: through being provided with first butterfly valve and second butterfly valve to the cooperation utilizes ventilative hose to carry out the flexible coupling with first butterfly valve and second butterfly valve, in order to eliminate the influence that the discharge gate title body support was dragged, and can control discharge gate below air current, the impact influence of the material impact symmetry body well, effectively promote the precision of measurement, and butterfly valve sealing performance is good, the gas tightness of the control title body that can be fine, further promote measurement accuracy, facilitate for the use.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention.
