A valve position controllable fixing clip for on-line maintenance of wall-mounted valve

Abstract

A valve location-controllable fixing clip for on-line maintenance of an adherent valve relates to a clip used for supporting. The middle part of a "U"-shaped support leg A (1) and the upper end of a casing pipe A (4) are fixedly connected; the middle part of a "U"-shaped support leg B (14) and the lower end of a casing pipe B (12) are fixedly connected; at least two planes (7) are arranged, and are oppositely arranged on the outer edge surface of a lead screw (8); an external thread A (6) and an external thread B (9) are opposite in thread direction; the casing pipe A (4) sheathes the external thread A (6); and the casing pipe B (12) sheathes the external thread B (9). According to the fixing clip disclosed by the invention, through the lead screw of which the upper end and the lower end are provided with the opposite threads and mutual matching between an upper support frame and a lower support frame respectively sheathing the upper end and the lower end of the lead screw, a valve rod is rapidly fixed when the adherent valve is maintained, so that a valve core is prevented from being scoured and falling off, and a valve location can also be enabled to keep opening required by process production, so that fluctuation in production is avoided.

Description

【Technical field】 [0001] The invention relates to a clip used for support, in particular to a clip with controllable valve position for on-line maintenance of a wall-attached valve. 【Background technique】 [0002] When the wall-mounted valve is maintained online, if the actuator needs to be repaired, the push rod of the actuator needs to be disengaged from the valve stem. In this case, the valve core will continue to be washed by the medium in the pipeline. If the valve stem is not repaired If it is fixed, when the flushing force is too large, the valve core and stem will be flushed into the container together, which may cause fluctuations or shutdown of the device. At the same time, due to the long maintenance time of the valve, the valve position cannot be controlled, which will have a great impact on production. 【Content of invention】 [0003] In order to overcome the deficiencies in the background technology, the present invention discloses an on-line maintenance valve...

[0002] When the wall-mounted valve is maintained online, if the actuator needs to be repaired, the push rod of the actuator needs to be disengaged from the valve stem. In this case, the valve core will continue to be washed by the medium in the pipeline. If the valve stem is not repaired If it is fixed, when the flushing force is too large, the valve core and stem will be flushed into the container together, which may cause fluctuations or shutdown of the device. At the same time, due to the long maintenance time of the valve, the valve position cannot be controlled, which will have a great impact on production.
