Abstract
The utility model relates to a gas valve, which is used for particularly solving the on-line detection of valves. The utility model discloses a double-seal gas butterfly valve which is capable of on-line detection. The utility model comprises a valve body, a valve rod and a valve plate. The utility model is characterized in that both sides of the valve plate are provided with symmetrical seal rings, and the radial direction of a valve body is provided with a detection hole. Sealing property can be detected by a detector when the valve is closed, and gas pressure or temperature in a gas pipeline can be detected on line by the detector when the valve is opened.
Description
Technical field
The utility model relates to gas valve, specifically belongs to the gas cut-off valve.
Background technique
Gas fuel butterfly valve has compact structure, and the characteristics that flow resistance is little are widely used in combustion gas and dam in the pipeline.The erosion of adamant influences the valve seal performance in the combustion gas but exist.For guaranteeing under valve in off position reliable sealing performance to be arranged, must carry out sealing and measure, and existing valve is single sealing configuration, can't detect.
Summary of the invention
Be to solve the online detection of valve, the purpose of this utility model provides a kind of double-sealing Gas fuel butterfly valve that can online detection, and it can measure sealability, the temperature and pressure of valve.
The utility model is to realize that by following technological scheme it includes valve body, valve rod, valve plate, and its structure outline is to be arranged with two seal rings on the valve plate, and valve body radially is provided with one and detects the hole, and this hole and valve body hole are connected.
The center line in above-mentioned detection hole and valve rod and valve body hole center line intersect.
The utility model is simple in structure, because only adopt double sealing structure and on valve body, offer one and detect the hole on the valve plate two sides, and measurement sealing in the time of just making valve closing, gaseous-pressure and temperature parameter in the measuring channel when valve opening.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view cutaway drawing of the utility model structure.
Embodiment
Embodiment below with reference to accompanying drawing is further described the utility model.
Among Fig. 1 and Fig. 2, valve plate 1 is housed in the valve body hole 6, double density seal 2 is equipped with by screw in the valve plate two sides.During valve closing, the sealing sword of two seal rings all fits tightly with valve body 3 sealing surfaces.Two seal rings are separated into A, B, three inner chambers of C with valve body hole 6, and B chamber and A, C chamber completely cut off.Be drilled with one on the valve body 3 and detect hole 5, detect the hole and communicate with valve body hole, the center line that detects the hole intersects with valve rod 4 and valve body hole center line, detects the technical parameter that the hole can be used to measure valve.When valve is under the closed condition, can detect sealing with detector.Valve rod 4 is used for rotational valve plate 1, when valve is under the opening state, with detector can online detection gas pipeline in gas pressure or temperature.
