Description

Technical Field

[0001] The utility model relates to the technical field of valve body equipment, in particular to a valve body equipment which is convenient for emergency cutting off. Background Art

[0002] A ball valve is a rotary valve that controls the flow of liquid or gas by rotating the ball. The ball is usually made of metal and its rotation angle can be controlled by controlling the valve stem or motor to open or close the fluid.

[0003] At present, in the prior art, most of the leakage of ball valves is often caused by the failure of the seal at the connection between the inner ball and the handle of the ball valve. When transporting some special liquids, the failure of the seal will cause a gap that is difficult for the naked eye to detect, which can cause great harm to the surrounding area. In view of this, we propose a valve body device that is easy to cut off in an emergency. Utility Model Content

[0004] The main purpose of the utility model is to provide a valve body device that is convenient for emergency cutting off, which can solve the problems raised in the above technical background.

[0005] To achieve the above-mentioned purpose, the utility model proposes a valve body device for emergency shutoff, comprising a device body, a detection mechanism is provided on the surface of the device body, a closing mechanism is fixedly connected to the surface of the device body, and the detection mechanism comprises:

[0006] An outer ring, the surface of which is fixedly connected to the surface of the device body, the inner wall of which is slidably connected to a sponge block, the bottom surface of which is fixedly connected to a gasket, and the surface of the gasket is slidably connected to the inner wall of the outer ring.

[0007] Preferably, an inclined slider is slidably connected to the inner wall of the outer ring, a spring switch is fixedly connected to the inner wall of the outer ring, and a detection end of the spring switch is fixedly connected to the surface of the inclined slider.

[0008] Preferably, the device body comprises a ball valve shell, an inner wall of the ball valve shell is rotatably connected to an inner sphere, and an upper surface of the inner sphere is fixedly connected to a bottom surface of the handle.

[0009] Preferably, the closing mechanism comprises a lower protective shell, the surface of the lower protective shell is hinged to two sides of the electric push rod, the inner wall of the electric push rod is slidably connected with a connecting rod, and the electric push rod is electrically connected to the detection mechanism.

[0012] Beneficial Effects

[0013] The utility model provides a valve body device that is convenient for emergency cutting and has the following beneficial effects:

[0014] (1) The valve body device that facilitates emergency shutoff has a detection mechanism. When the liquid transported inside the device body breaks through the seal between the ball valve shell and the inner ball body and reaches the handle, the sponge block absorbs the liquid, causing the weight of the sponge block to increase. As a result, the sponge block pushes the inclined slider to move under the action of gravity, causing the inclined slider to move and trigger the spring switch, thereby activating the closing mechanism. Compared with manual inspection, the inspection through the detection mechanism is more accurate and rapid.

[0015] (2) The valve body device that facilitates emergency shutoff has a closing mechanism. When the detection mechanism is activated, the electric push rod pushes the upper protective shell to flip, so that the upper protective shell and the lower protective shell are closed, and the internal liquid is sealed to avoid liquid leakage. When the electric push rod is pushed to the maximum stroke, the clamping plate clamps the handle. At this time, the stepper motor starts to push the clamping plate to rotate, so that the device body is cut off in time, so that workers do not need to cut it off manually, protecting workers from being harmed by the liquid inside the device body.
