Description
The technical field is as follows:
the utility model belongs to the technical field of the valve is made, concretely relates to overflow protection gas valve part.
Background art:
the gas valve sold in the market at present, the kind of case is different, the utility model relates to a novel can cut off the gas valve inner structure of flow automatically.
The gas valve is a novel safety matching device for gas pipeline engineering; the gas valve is used for cutting off, connecting and adjusting gas in a pipeline, and has good control characteristics and closing sealing performance; it is suitable for various gas medium pipelines such as city gas, liquefied petroleum gas, natural gas and oxygen. The existing gas valves have no gas over-flow control function and poor safety.
The utility model has the following contents:
the utility model aims at overcoming the deficiencies that exist of above-mentioned prior art, provide a cross flow protection gas valve part.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a cross flow protection gas valve part, the protective member include leading truck and hemisphere spill float, hemisphere spill float locate in the leading truck, hemisphere spill float both ends be connected with the connecting rod, the leading truck include upper portion cross arm and lower part casing, leading truck upper portion cross arm center be equipped with the connecting rod through-hole, hemisphere spill float top connecting rod from bottom to top pass the connecting rod through-hole, hemisphere spill float top connecting rod cover be equipped with the spring.
The connecting rod through hole department be equipped with the spill round platform, top connecting rod top be equipped with the valve hoop, spring overlap joint set up between hair hoop and spill round platform.
The over-flow protection gas valve component is arranged in the direction of a gas inlet of an inner cavity of the gas valve.
The guide frame is integrally formed.
The outer contour shape of the guide frame is consistent with that of the inner cavity of the gas valve, so that the guide frame and the gas valve are arranged in a fit mode.
When no fuel gas is introduced into the over-flow protection fuel gas valve part, the spring is in a natural extension state, and the upper part of the hemispherical concave floater is attached to the lower part of the cross bracket; when the gas is introduced, the spring is in a compressed state.
The use process of the over-flow protection gas valve component is as follows:
when the gas pressure exceeds an allowable value, the hemispherical concave floater rapidly moves downwards to be in contact fit with the inner wall of the guide frame shell and sealed under the gas stamping, the gas flow is blocked, the gas is automatically closed, and the purpose of safety protection is achieved.
The utility model has the advantages that:
the utility model discloses a cross flow protection gas valve part and simple structure under the condition that does not change valve structure, can realize that the valve adjusts self according to the size of airflow, when gas utensil or pipeline gas leakage, flow are too big, self-closing gas to the personal safety of protection, the material resources of using manpower sparingly by a wide margin, reduce cost, and can improve work efficiency, environmental protection.
Description of the drawings:
fig. 1 is a schematic structural view of an overflow protection gas valve in embodiment 1 of the present invention;
fig. 2 is a perspective view of the structure of the overflow protection gas valve in embodiment 1 of the present invention;
fig. 3 is a schematic sectional view of an overflow protection gas valve a-a according to embodiment 1 of the present invention; wherein:
1-valve hoop, 2-connecting rod, 3-spring, 4-cross bracket, 5-hemispherical concave floater, 6-concave round table and 7-shell.
The specific implementation mode is as follows:
the present invention will be described in further detail with reference to examples.
Example 1
A structure schematic diagram of an over-flow protection gas valve component is shown in figure 1, a-A is shown in figure 3 in a cross-sectional structure schematic diagram, a perspective diagram is shown in figure 2, the protection component comprises a guide frame and a hemispherical concave floater 5, the hemispherical concave floater 5 is arranged in the guide frame, two ends of the hemispherical concave floater 5 are connected with connecting rods 2, the guide frame comprises an upper cross support 4 and a lower shell 7, a connecting rod through hole is formed in the center of the upper cross support 4 of the guide frame, the connecting rod 2 above the hemispherical concave floater 5 penetrates through the connecting rod through hole from bottom to top, a spring 3 is sleeved on the connecting rod 2 above the hemispherical concave floater 5, a concave round table 6 is arranged at the connecting rod through hole, a valve hoop 1 is arranged at the top of the upper connecting rod 2, and the.
The over-flow protection gas valve part is arranged in the direction of a gas inlet of an inner cavity of the gas valve.
The guide frame is integrally formed, and the outline shape of the guide frame is consistent with that of the inner cavity of the gas valve so as to realize the joint arrangement of the guide frame and the gas valve.
When no fuel gas is introduced into the over-flow protection fuel gas valve part, the spring 3 is in a natural extension state, and the upper part of the hemispherical concave floater 5 is attached to the lower part of the cross bracket 4; when the gas is introduced, the spring 3 is in a compressed state.
The use process of the over-flow protection gas valve part is as follows:
the gas valve is opened, gas flows to the direction of the lower part of the guide frame along the gap of the guide frame from the upper part of the guide frame, a flowing path is realized, in the flowing process of the gas, the hemispherical concave floater 5 moves downwards under the action of gas pressure and drives the connecting rod 2 to compress the spring 3, when the gas pressure exceeds an allowable value, the hemispherical concave floater 5 rapidly moves downwards under the stamping of the gas, penetrates through the shell 7 and is attached to the inner wall of the gas valve, the gas flow is blocked, and the gas is automatically closed, so that the safety protection is realized.
