Abstract
The utility model discloses a diaphragm valve, which comprises a valve body, a diaphragm, a valve cover, a valve rod and a handle, wherein the two ends of the valve rod are provided with the diaphragm and the handle respectively; the valve rod is arranged on the valve cover in a penetrating manner; the valve body is arranged on one side of the valve cover; and a working medium is arranged in the valve body. According to the diaphragm valve, the purity of the working medium is guaranteed, the possibility of impact of the working medium to working components of an operating mechanism is prevented, and no medium leakage is produced; and the diaphragm valve can also be used for conditions with chemical corrosion or suspension particle working medium.
Description
Technical field
The utility model relates to a kind of membrane valve.
Background technique
The effect of block valve is by connecting or block the medium in the pipeline, for example in the gas pipeline, after in a single day pipeline breaks, block valve for pipeline is realized the autoshutdown of valve according to the rate of pressure reduction of pipeline, but if pipeline breaking occurs, be easy to make pipeline medium impulse maneuver mechanism, thereby affect the purity of working medium.
The model utility content
The model utility purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, to provide a kind of simple in structure, reliable performance and the membrane valve of working in the situation with chemical corrosion or suspended particulate working medium again.
Technological scheme: in order to realize above purpose, a kind of membrane valve described in the utility model, it comprises valve body, barrier film, valve gap, valve rod and handle, the two ends of described valve rod are respectively equipped with barrier film and handle, described valve rod is located on the valve gap, and a side of valve gap is provided with valve body, is provided with working medium in the described valve body.
Beneficial effect: a kind of membrane valve that the utility model provides, disconnect by operating mechanism and the medium channel that will be positioned at the barrier film top, guarantee the degree of purity of working medium, and prevented the possibility of working medium impulse maneuver mechanism workpiece; Because the parts such as valve rod are not subjected to dielectric corrosion, thereby have saved packing seal structure, have saved cost, and can not produce the medium leakage, therefore, this membrane valve can also be used in the situation with chemical corrosion or suspended particulate working medium.
Description of drawings
Fig. 1 is sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
Be illustrated in figure 1 as a kind of membrane valve described in the utility model, it comprises valve body 1, barrier film 2, valve gap 3, valve rod 4 and handle 5.
The two ends of described valve rod 4 are respectively equipped with barrier film 2 and handle 5, and described valve rod 4 is located on the valve gap 3, and a side of valve gap 3 is provided with valve body 1, is provided with working medium in the valve body 1.
When needs are opened or are closed valve body 1, turn handle 5, at this moment, barrier film that valve rod 4 one sides are provided with 2 is done elevating movement along valve rod axis, and the distortion by barrier film 2 separates actuating mechanism and medium, has realized the connection of valve body 1 interior pipeline and blocks.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model Spirit Essence all should be encompassed within the protection domain of the present utility model.
