Abstract
The utility model relates to a three-way valve position identification means belongs to valve body technical field. The valve mainly comprises a valve body, a diaphragm, a movable rod, a diaphragm cover and a valve position indicating rod, wherein the diaphragm can be axially movably arranged in the valve body through the movable rod, the diaphragm cover is arranged at the top of the valve body, and the valve position indicating rod vertically penetrates through the diaphragm cover and is fixedly connected to the movable rod; the top of the membrane cover is provided with a transparent cover; the utility model can accurately indicate the position of the valve core; when the valve core stroke has a dead point, the valve core position can be identified through the valve position identification scale, whether a fault occurs or not is judged visually, the maintenance time is shortened, and the production efficiency is improved.
Description
Technical Field
The utility model belongs to the technical field of the valve body, in particular to three-way valve position identification means.
Background
The back washing valve and the special hydraulic control valve are driven by the pressure of a pipeline system, and can automatically switch between two positions and three ways, so that the automatic back washing of the filter is realized. Be applied to the supporting two tee bend back flush valves of disk filter, a unit of disk filtration system comprises the multiunit and a blow off pipe of sharing, but in the long-time use of three-way valve, the valve body, the case, form one-way stroke card after the diaphragm corrosion and die etc. the drain is closed untight or not closed when the three-way valve is in the filtration state, lead to the system blow off pipe to last unusual drainage, because the three-way valve can't discern whether the diaphragm is in utmost point position or card die position, lead to the state of opening and shutting of unable affirmation valve body, because the three-way valve is a plurality of parallel operation, can't judge that group and which three-way valve trouble, it is more difficult to overhaul, seriously influence the normal work of equipment.
Disclosure of Invention
In order to overcome the problems in the background art, the utility model provides a three-way valve position marking device, which can accurately indicate the position of a valve core, is convenient for adjustment and ensures the accurate flow control; when the valve core stroke has a dead point, the valve core position can be identified through the valve position identification scale, whether a fault occurs or not is judged visually, and the maintenance is convenient.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: a three-way valve position marking device mainly comprises a valve body, a diaphragm, a movable rod, a diaphragm cover and a valve position indicating rod, wherein the diaphragm can be axially movably arranged in the valve body through the movable rod; the top of the membrane cover is provided with a transparent cover.
The utility model has the advantages that:
the utility model can accurately indicate the position of the valve core; when the valve core stroke has a dead point, the valve core position can be identified through the valve position identification scale, whether a fault occurs or not is judged visually, the maintenance time is shortened, and the production efficiency is improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
The utility model discloses a three-way valve position marking device, which mainly comprises a valve body 1, a diaphragm 2, a movable rod 3, a membrane cover 4 and a valve position indicating rod 5, wherein the diaphragm 2 can be axially movably arranged in the valve body 1 through the movable rod 3, the membrane cover 4 is arranged at the top of the valve body 1, and the valve position indicating rod 5 vertically passes through the membrane cover 4 and is fixedly connected on the movable rod 3; the transparent cover 6 is arranged at the top of the membrane cover 4, so that the valve position indicating rod 5 is prevented from being collided and bent, the friction resistance is large during expansion and contraction, and the extending amount of the valve position indicating rod 5 can be visually observed through the transparent cover 6; when the valve is in a filtering state (C-B) (as shown in figure 1), the top of the valve position indicating rod 5 is flush with the top of the membrane cover 4; when the valve is in a back flushing sewage discharge state (B-A) (as shown in figure 2); the position of the diaphragm 2 can be accurately indicated; when the stroke of the diaphragm 2 has a dead point, the top of the valve position indicating rod 5 is contacted with the top of the transparent cover 6; the position of the diaphragm 2 can be identified through the valve position indicating rod 5, whether a fault occurs or not is judged visually, the maintenance time is shortened, and the production efficiency is improved.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
