Abstract
The utility model discloses a butterfly valve with a dissolution layer. The dissolution layer is fixedly connected to a valve body of the butterfly valve. The dissolution layer comprises a first side edge, a second side edge, a top edge, an air inlet and an air outlet. The first side edge and the second side edge are respectively of an annular structure. The inner side walls of the first side edge and the second side edge are fixedly connected to the portion between two flanges on the valve body in a sleeved mode. A gap is formed between the first side edge and the flange adjacent to the first side edge, and a gap is formed between the second side edge and the flange adjacent to the second side edge. The top edge is of an annular structure. The two end faces of the top edge are fixedly connected with the upper end of the first side edge and the upper end of the second side edge respectively. A sealing structure is formed by the first side edge, the second side edge and the top edge. The top edge or the side edges are provided with the air inlet and the air outlet. The air inlet is connected with a hot air source. According to the butterfly valve with the dissolution layer, due to the arrangement of the dissolution layer, materials are prevented from being condensed on the edge of a valve clack in a heating mode and the use of the valve is effectively ensured in the using process of the valve.
Description
Technical field
The utility model belongs to valve processing technique field, relates in particular to a kind of butterfly valve with dissolving layer.
Background technique
Valve is the controlling component in fluid delivery system, have cut-off, adjusting, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various, produce and use standard without unified, production firm often goes to manufacture according to user's actual demand.
On some chemical substance conveyance conduit, valve can form stickum at the edge of flap after having grown service time, so that make flap closure completely, thereby make valve lose cutting action, therefore, can effectively address the aforementioned drawbacks in the urgent need to a kind of valve.
Summary of the invention
The purpose of this utility model provides a kind of butterfly valve with dissolving layer, to solve in prior art on some chemical substance conveyance conduit, after valve has been grown service time, edge at flap can form stickum, so that make flap closure completely, thereby make valve lose the defect of cutting action.
In order to realize the purpose of this utility model, the utility model provides a kind of butterfly valve with dissolving layer, described dissolving layer is fixedly connected on the valve body of described butterfly valve, described dissolving layer comprises first side, second side and top margin, suction port, air outlet, described first side and second side are cirque structure, its madial wall fixedly sleeved on described valve body two flange intermediate portions, and described first side and second side are respectively at having gap between the flange to contiguous, described top margin is cirque structure, the both ends of the surface of described top margin are fixedly connected with upper end, second side respectively at described first side, described first side, second side and top margin form sealing configuration, described top margin or side are provided with suction port and air outlet, described suction port and described air outlet are symmetrical arranged, described suction port is connected with hot gas source.
Wherein, described first side is all fixedly connected with described valve body by the mode of welding with second side, and described top margin is fixedly connected with second side with described first side by the mode of welding.
Wherein, described suction port is that multiple and air outlet is multiple.
The utility model; compared with prior art, by dissolving layer is set, make valve in the process using; by the mode of heating; avoid material to condense in the edge of flap, effectively ensured the use of valve, hot gas source of the present utility model can also adopt industrial waste gas to serve as; having realized industrial waste gas effectively utilizes; improved energy utilization rate, through the waste gas of dissolving layer effectively lower temperature, environmental protection has been played to important function.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure, 1-valve body, 2-first side, 3-second side, 4-top margin, 5-suction port, 6-air outlet.
Embodiment
In order to make the purpose of this utility model, technological scheme and beneficial effect clearer, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1, the utility model provides a kind of butterfly valve with dissolving layer, described dissolving layer is fixedly connected on the valve body of described butterfly valve, described dissolving layer comprises first side, second side and top margin, suction port, air outlet, described first side and second side are cirque structure, its madial wall fixedly sleeved on described valve body two flange intermediate portions, and described first side and second side are respectively at having gap between the flange to contiguous, described top margin is cirque structure, the both ends of the surface of described top margin are fixedly connected with upper end, second side respectively at described first side, described first side, second side and top margin form sealing configuration, described top margin or side are provided with suction port and air outlet, described suction port and described air outlet are symmetrical arranged, described suction port is connected with hot gas source.
When use, suction port is connected to hot gas source, hot gas, after dissolving layer, is discharged from air outlet, through hot gas cycle, has improved the temperature of valve body, and heat is delivered to flap edge by valve body, by the mode heating up, prevents condensing of pollutant.Above-mentioned suction port and air outlet are symmetrical arranged preferentially fingering gas port and air outlet and are symmetrical arranged with the center of circle on circumferential surface, by symplex structure ensured hot gas the largest contact with described valve body surface, improve heat utilization efficiency; Gap is all left with flange in first side and second side, used when gap is fixed for valve and pipeline.In the utility model, can directly utilize the hot gas discharging in pipeline transmission directly to serve as hot gas source, in this way, tool has the following advantages profit: 1. protection of the environment, and 2. waste utilization, 3., without increasing new equipment, reduces costs, and 4. simple in structure, replicability is strong.
Wherein, described first side is all fixedly connected with described valve body by the mode of welding with second side, and described top margin is fixedly connected with second side with described first side by the mode of welding.
Means of fixation has multiple, can pass through the modes such as welding, bolt connection.
Wherein, described suction port is that multiple and air outlet is multiple.If the temperature of hot gas source is lower, for ensureing solute effect, can utilize many suction ports and have more gas port, improve airspeed, promote solute effect.
The utility model; compared with prior art, by dissolving layer is set, make valve in the process using; by the mode of heating; avoid material to condense in the edge of flap, effectively ensured the use of valve, hot gas source of the present utility model can also adopt industrial waste gas to serve as; having realized industrial waste gas effectively utilizes; improved energy utilization rate, through the waste gas of dissolving layer effectively lower temperature, environmental protection has been played to important function.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
