Abstract
The utility model relates to a ball valve field, concretely relates to locking mechanism ball valve has. It includes locking mechanism, end a position dog, valve body, case, valve rod and rotatory dog, adorns in the case in the middle of the valve body, and the valve rod is connected to the case upper end, and the valve rod lies in upper end in the middle of the valve body, and rotatory dog is equipped with to the valve rod upper end, and the design of valve body upper end has the position of an ending dog, rotatory dog with end position dog cooperation installation, the valve rod upper end is rotatory is equipped with locking mechanism and lies in and end position dog top. The advantage is design benefit, and is rational in infrastructure, and locking mechanism's design ensures that the ball valve can not self -closing, ensure the ball valve at normal condition, safe and reliable has solved the potential safety hazard, guarantees the equipment safe operation, reduces and unnecessarily loses.
Description
Technical field
The utility model relates to ball valve field, is specifically related to one and has lockable mechanism ball valve.
Background technique
In air-conditioning refrigeration system, ball valve was in normally open in the past, because equipment operation can produce vibrations in air-conditioning refrigeration system, ball valve inherently 90-degree rotation is exactly switch, and under shock effect, ball valve can be easy to automatic closedown for a long time, cause system malfunctions, cause damage.
Summary of the invention
In order to solve above-mentioned model utility problem, the utility model proposes one and there is lockable mechanism ball valve, designing ingenious, simple and compact for structure, solve the automatic closing problem of ball valve, reduce fault and occur.
In order to reach above-mentioned model utility object, the utility model proposes following technological scheme:
There is lockable mechanism ball valve, it comprises lockable mechanism, stop bit block, valve body, spool, valve rod and rotary block, spool is loaded in the middle of valve body, spool upper end connects valve rod, valve rod is positioned at upper end in the middle of valve body, and rotary block is equipped with in valve rod upper end, and valve body upper end is designed with stop bit block, rotary block and stop bit block coordinate to be installed, and the rotation of valve rod upper end is equipped with lockable mechanism and is positioned at above stop bit block.
Described lockable mechanism comprises semicircular ring, block arc, round pin, and semicircular ring lower end inside is equipped with round pin, and round pin is contained in valve rod upper end, and block arc is arranged on the side of side, top, semicircular ring ground.
Described rotary block is arc-shaped, and 1/4 is circular, and rotary block is contained in valve rod upper end by jump ring.
Described stop bit block is semicircle shape, rotary block be loaded on stop bit block side and between form 1/4 arc-shaped opening.
The utility model has the advantages that design is ingenious, rational in infrastructure, the design of lockable mechanism guarantees that ball valve can not be closed automatically, guarantees that ball valve is in normal state, safe and reliable, solves potential safety hazard, ensures equipment safety operation, reduces unnecessary loss.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the close-up schematic view of the utility model closed condition.
Fig. 3 is the schematic diagram of lockable mechanism of the present utility model.
Embodiment
In order to further illustrate the utility model, introduce below in conjunction with Figure of description:
With reference to accompanying drawing, there is lockable mechanism ball valve, it comprises lockable mechanism 1, stop bit block 2, valve body 3, spool, valve rod 4 and rotary block 5, be loaded on spool in the middle of valve body 3, spool upper end connects valve rod 4, and valve rod 4 is positioned at the middle upper end of valve body 3, rotary block 5 is equipped with in valve rod 4 upper end, valve body 3 upper end is designed with stop bit block 2, and rotary block 5 and stop bit block 2 coordinate to be installed, and the rotation of valve rod 4 upper end is equipped with lockable mechanism 1 and is positioned at above stop bit block 2.
Described lockable mechanism 1 comprises semicircular ring 11, block arc 12, round pin 13, and semicircular ring 11 lower end inside is equipped with round pin 13, and round pin 13 is contained in valve rod 4 upper end, and block arc 12 is arranged on the side of side, semicircular ring 11 top.
Described rotary block 5 is arc-shapeds, and 1/4 is circular, and rotary block 5 is contained in valve rod 4 upper end by jump ring.
Described stop bit block 2 is semicircle shapes, rotary block 5 be loaded on stop bit block 2 side and between form 1/4 arc-shaped opening.
When the utility model uses, valve rod 90-degree rotation is just opened, rotary block rotates along with valve rod, 90-degree rotation, rotary block will withstand stop bit block, at this moment valve open and do not worry that valve is opened not in place or opened, the semicircular ring of lockable mechanism rotate around valve rod block arc is formed between rotary block and stop bit block 1/4 arc-shaped opening in, such block arc is just stuck between rotary block and stop bit block, rotary block would not rotary closing valve, valve would not be closed under shock effect, safe and reliable; The semicircular ring of lockable mechanism can be rotated around valve rod by round pin, during valve closing, semicircular ring rotates around valve rod upper end and is positioned at above stop bit block, and the block arc of lockable mechanism is then removed between rotary block and stop bit block, rotary block just can rotate back, valve closing.The arc length of block arc is less than the 1/4 arc-shaped opening arc length formed between rotary block and stop bit block, guarantees that block arc can be stuck between rotary block and stop bit block.
