Description
Technical Field
The utility model relates to a glasses valve subassembly, concretely relates to open-type eyes valve auto-lock locking device belongs to blast furnace system subassembly technical field.
Background
The gas system is a necessary component of the blast furnace, wherein, a glasses valve is required to be installed in the gas system to control the gas, and the glasses valve is also called a fan-shaped glasses valve, a fan-shaped blind plate valve, a flap valve and a fan-shaped valve, is widely used in gas medium management systems of industries such as industrial and mining enterprises, municipal administration, environmental protection and the like, and is particularly suitable for absolute cutoff of harmful, toxic and inflammable gases; the blind plate is also suitable for being used as a blind plate of a pipeline terminal so as to shorten the overhaul time or facilitate the connection of a new pipeline system; the blind plate valve is provided with three driving devices, wherein the three driving devices are two manual clamping or loosening devices, one electric device is used for opening or closing the flashboard, the two manual devices are firstly loosened in the process of opening or closing the flashboard, and then the electric device is started, so that the purpose of opening or closing the flashboard is achieved (after the flashboard is opened or closed, the two manual devices are clamped, a pipeline can work, the existing gas system on the blast furnace is generally provided with a 2400 open type eye valve, and a large amount of gas can be greatly damaged to peripheral personnel or even cause casualties due to the fact that staff naturally loosen when an operation error occurs or a valve tightening device fails.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an open-type eye valve auto-lock locking device through increasing behind the locking mechanism, can prevent gas leakage, improves the production security.
The utility model discloses an open eye valve self-locking anti-loosening device, which comprises a valve body; and a clamping seal arranged on two sides of the valve plate of the valve body; the glasses valve clamping device is arranged between the valve body and the clamping seal, and the anti-loosening mechanism is also arranged between the valve body and the clamping seal; the anti-loosening mechanism comprises a plurality of internal spiral tubes and screw adjusting rods screwed with the internal spiral tubes; the internal thread spiral pipe is fixed on the side of the glasses valve clamping device and is fixed with the valve body; one end of the screw adjusting rod is connected with the internal thread spiral pipe in a screwing mode, and the other end of the screw adjusting rod is tightly propped against the tightening seal.
As a preferred embodiment, a top plate is fixed at one end of the screw adjusting rod, which is far away from the internal thread spiral pipe.
In a preferred embodiment, after the screw adjusting rod is completely screwed into the internal thread spiral pipe, the top surface of the top plate of the screw adjusting rod does not exceed the top surface of the glasses valve clamping device.
Compared with the prior art, the utility model discloses an open-type eye valve auto-lock locking device; after increasing locking mechanism, can effectually prevent that the improper operation of eye valve from loosening, also can carry out the secondary when appearing tightening not tight gas leakage and tighten through adjusting screw, also do not hinder the normal operating of eye valve.
