Receiving channel, the receiving channel are arranged in filter plate close to the side in flow inlet direction and are contradicted with filter plate, the receiving
Connecting plate is installed in channel, the valve body is equipped with capping, driving lidstock is connected between the capping and connecting plate
The actuator of receiving channel free end, one end of the receiving channel connecting passage is installed with to be extended and not towards filter plate direction
Contradict the obstruction filter plate of filter plate.
By using above-mentioned technical proposal, impurity enters inside runner with fluid from flow inlet, due to filter plate
It is obliquely installed mode so that the receiving that the impurity filtered can enter under the percussion of fluid below filter plate is led to
Inside road.And it enters after the fluid inside receiving channel can form a convolution with impurity inside receiving channel and is continuously introduced to
In runner, the fluid that reduction formation convolution is arranged by stopping filter plate is taken the impurity in receiving channel out of receiving and is led to
Road；By actuator driving capping far from receiving channel, for receiving channel to be discharged in impurity, realize the cleaning to impurity and is prevented
Only there is a phenomenon where blocking, to promote the practicability of the forged steel check valve in actual use.
It is further arranged to：The outflow port direction of the free end of the receiving channel towards runner is obliquely installed.
By using above-mentioned technical proposal, in such a way that receiving channel is set as being obliquely installed so that convolution is in appearance
The fluid of channel interior received can enable impurity to be preferably trapped in receiving logical preferably towards the direction movement stopped where filter plate
In road.
It is further arranged to：The actuator is screw rod, and the screw rod is threadedly coupled with connecting plate and end face is fixedly arranged on
Capping, reinforcing rib is fixedly connected between the connecting plate and the inner wall of receiving channel.
By using above-mentioned technical proposal, capping drives screw rod rotation, passes through the threaded connection between screw rod and connecting plate
Mode realizes keying of the capping for receiving channel free end, and increases connecting plate and receiving channel by the setting of reinforcing rib
Between structural strength.
It is further arranged to：The obstruction filter plate is equipped with to extend internally towards receiving channel towards the side of filter plate to be prolonged
Stretch filter plate portion.
By using above-mentioned technical proposal, the setting for extending filter plate portion plays better blocking to the impurity in swirling flow body
Effect so that impurity can be preferably trapped in inside receiving channel.
It is further arranged to：Sealing ring is equipped between the receiving channel and capping, the capping is equipped with for sealing ring
The groove being embedded.
By using above-mentioned technical proposal, the setting of sealing ring increases the leakproofness between receiving channel and capping, prevents
The phenomenon that fluid leaks, and the contact area between sealing ring and capping is increased by the setting of groove, reach better
Sealing effect.
It is further arranged to：The receiving channel, which is equipped with, sets for sealing ring card and limits sealing ring disengaging receiving channel
Card slot.
By using above-mentioned technical proposal, the card of card slot, which is set, realizes that sealing ring is fixed in receiving channel, makes capping and holds
It receives between channel in separation, sealing ring need not be repositioned, facilitate the keying operation of receiving channel.
It is further arranged to：Deformation cavity is equipped in the sealing ring.
By using above-mentioned technical proposal, the setting of deformation cavity enables sealing ring preferably to deform upon, to real
The now more preferable sealing between capping and receiving channel.
In conclusion the utility model has the advantages that：The present invention can be to filtering on the basis of realizing and filtering
Impurity cleared up, to promote the practicability of the forged steel check valve in actual use.
