Abstract
The invention relates to the field of ball valves, in particular to a ball calve with a locking mechanism. The ball valve with the locking mechanism comprises the locking mechanism, a stopping dog, a valve body, a valve element, a valve rod and a rotating dog. The middle portion of the valve body is installed in the valve element, the upper end of the valve element is connected with the valve rod, the valve rod is located at the upper end of the middle of the valve body, the rotating dog is installed at the upper end of the valve rod, the stopping dog is designed at the upper end of the valve body, the rotating dog and the stopping dog are installed corporately, and the locking mechanism is rotatably installed at the upper end of the valve rod and is located above the stopping dog. The ball valve with the locking mechanism has the advantages that the design is skillful, the structure is reasonable, it is guaranteed that the ball valve cannot be closed automatically through the design of the locking mechanism, the ball valve is guaranteed to be in a normal state, the advantages of being safe and reliable are achieved, a potential safety hazard is solved, equipment is guaranteed to operate securely, and unnecessary loss is decreased.
Description
Technical field
The present invention relates to ball valve field, be specifically related to one and there is 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 foregoing invention problem, the present invention 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 foregoing invention object, the present invention 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.
Advantage of the present invention is that design is ingenious, rational in infrastructure, and 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 invention.
Fig. 2 is the close-up schematic view of closed condition of the present invention.
Fig. 3 is the schematic diagram of lockable mechanism of the present invention.
Embodiment
In order to the present invention is further described, 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 present invention 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.
