Abstract
A carbon black off-gas blow off valve device with good air impermeability comprises a blow off valve, a valve body, a valve door and a connection rod, wherein the upper portion of the blow off valve is provided with the valve body, the valve body is a U-shaped groove in structure, and the valve door is installed on the upper portion of the valve body, is provided with a downward bending edge, and is connected with the connection rod. The carbon black off-gas blow off valve device with the good air impermeability has the safety precaution function of an ordinary carbon black off-gas blow off valve. The valve door and the valve body are designed in a meshed structure, and therefore the air impermeability of a carbon black off-gas blow off valve is improved, carbon black off-gas leakage of the blow off valve is effectively prevented, and the structure is practical and safe.
Description
Technical field
The utility model relates to a kind of tail gas and diffuses control valve unit, relates in particular to a kind ofly to have good bubble-tight carbon black tail gas and diffuse control valve unit.
Background technique
To diffuse valve be when the pressure at control point surpasses setting value to existing tail gas in the carbon black process, promptly discharges the valve of a certain amount of gas, as a kind of safety early warning device; The existing valve that diffuses control valve unit lacks necessary Seal Design; In use, valve receives the effect of tail gas pressure, because poor sealing performance; How therefore the leakage that causes a small amount of tail gas to continue improve the sealing that carbon black tail gas diffuses valve and be still a problem demanding prompt solution.
Summary of the invention
The purpose of the utility model is to provide a kind of to be had good bubble-tight carbon black tail gas and diffuses control valve unit, and it can effectively solve, and carbon black tail gas diffuses valve because the tail gas that poor sealing performance caused continues leakage problem.
The utility model realizes that like this it comprises exhaust stack, valve body, valve, connecting rod, it is characterized in that the top of exhaust stack is provided with valve body; Valve body is a U type groove structure; The top of valve body is provided with valve, and valve has the edge of downward bending, and valve connects connecting rod.
The technique effect of the utility model is: the utlity model has and generally diffuse valve safe early warning function; Simultaneously, owing to the edge of bending match valve, improved the airtight performance that diffuses valve downwards with the U-shaped groove of valve body; Effectively prevented to diffuse valve tail gas leakage problem, the practical safety of structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model realizes that like this it comprises exhaust stack 1, valve body 2, valve 3, connecting rod 4; The top of exhaust stack 1 is provided with valve body 2, and valve body 2 is a U type groove structure, and the top of valve body 2 is provided with valve 3; Valve 3 has the edge of downward bending, and valve 3 connects connecting rod 4.In use, when the pressure in the exhaust stack 1 reaches set point, pressure jack-up valve 3; Valve 3 drivening rods 4, emit unnecessary tail gas after, valve 3 is closed; Valve 3 edge of bending downwards is inserted in the U type groove of valve body 2, in valve body 2, adds heat-preservation cotton or asbestos yarn, makes valve 3 and valve body 2 fit tightly; The occlusion structure design of valve 3 and valve body 2 has effectively improved air-tightness, has avoided the tail gas leakage.
