Technical field
The utility model is related to a kind of fluid control valve, more particularly to a kind of improved high-voltage check-valves.
Background technology
Check-valves belongs to a kind of automatic valve, and main function is to prevent medium from flowing backwards, prevent pump and drive motor anti-
Turn and vessel media released, be the primary element of fluid control engineering, be widely used in fluid line, it is traditional only
Return valve either swing check valve（It is rotated according to center of gravity）With lift check valve（It is moved along axis）All exist one it is shared
Disadvantage, i.e. shut-in time are long, and the refluence speed of water is fast, not can effectively prevent the hair for the phenomenon that water hammer and flap hit valve body
It is raw, noise is not only generated in the course of work, the service life of flap is had an effect on, due to certainly existing the fiber crops of part after Pipe installing
The foreign particles such as silk, welding slag or raw material band are easy to block sealing performance when leading to reflux at check valve seal and fail, cause serious
Leakage phenomenon, and existing universal check-valves is without filtering function, it is easier to cause to leak, serious economy is brought to user
Loss, therefore have and above-mentioned further improvement must be reduced user and bring unnecessary trouble.
Invention content
In view of the above-mentioned problems, the utility model proposes a kind of novel in structural design, there is movable overanxious function, and can be fast
The improved high-voltage check-valves that speed closes, can effectively prevent medium refluence to prevent water hammer to pump and pipeline damage.
To solve this technical problem, the utility model takes following scheme：A kind of improved high-voltage check-valves, including valve
Body, gland and flap, the valve body are partly equipped with the water inlet and water outlet of perforation medium in an axial direction, and the valve inner is set
There are Rotatable bracket, described holder one end to be equipped with flap and be bolted, prevents aqueous reflux for closing rapidly, the valve
It is equipped with gland above body, and is locked by bolt, sealing ring is equipped between the flap and valve body, between the gland and valve body
Equipped with gasket, it is additionally provided with shackle above the gland, movable filtering net is equipped at the valve inleting water mouth, and pass through valve body
Bottom, the fixed block are set to below movable filtering net, are used for plug filter net, are equipped with retainer ring below the fixed block, use
It prevents from falling off in conveniently blocking fixed block, O-ring seal together is equipped between the fixed block and valve body.
It is further improved to be：Filter hole is equipped at the valve inleting water mouth.
It is further improved to be：O-shaped slot is equipped on the outside of the fixed block, top is additionally provided with movable groove.
By using preceding solution, the utility model has the beneficial effects that：The utility model improved high-voltage check-valves, institute
It states and is equipped with movable filtering net at valve inleting water mouth, and pass through body base, the fixed block is set to below movable filtering net,
For plug filter net, retainer ring is equipped with below the fixed block, prevents from falling off for conveniently blocking fixed block, the fixed block with
One of O-ring seal is equipped between valve body, water inlet end design activity formula filter screen is mainly more convenient inside filter pipe
Impurity or foreign matter, prevent foreign matter from blocking sealing surface, if fixed block is dismantled more convenient cleaning filter screen, it is easier to extend leakproofness
Energy and service life, will not more occur leakage phenomenon, and it is extremely convenient to be brought to user, reduces the loss that user brings.
It is equipped with filter hole at the valve inleting water mouth, O-shaped slot is equipped on the outside of the fixed block, it is recessed that top is additionally provided with activity
Slot.
