Abstract
The utility model relates to a clamping plate type check valve with a flow guide disc. A valve core is arranged in a valve body. A pin shaft of the valve core is inserted with a positioning member. A spring is arranged between the valve core and the positioning member, and is used for pressing the valve core. The positioning member is integrally connected with the valve body. The positioning member is a flow guide disc type positioning member. A streamline-shaped inner cavity of the check valve is matched with the flow guide disc of the positioning member, and then a smooth liquid flow channel is formed. The liquid flowing through the valve body has small impact with parts in the valve, the flow speed is uniform and regular, the resistance coefficient of the check valve is decreased, and thus the hydraulic loss of the check valve is reduced.
Description
The utility model relates to a kind of clamp plate type safety check, particularly with the clamp plate type safety check of diversion disk.
In the prior art, do not have diversion component in the inner chamber of pipeline with the clamp plate type safety check, current are in disturbance state, cause hydraulic loss big.
The purpose of this utility model provides diversion component in a kind of inner chamber, can reduce the clamp plate type safety check of the band diversion disk of hydraulic loss.
The purpose of this utility model realizes by following measure, in the valve body 3 of the clamp plate type safety check of band diversion disk spool 1 is housed, the bearing pin of spool 1 and locating piece are pegged graft, spring 2 is arranged between spool 1 and the locating piece, in order to pressed spool 1, locating piece is connected with valve body 3 one, and described locating piece is a water conservancy diversion disc type locating piece 4, and the diversion disk concave surface of described locating piece is facing to the water intake direction.The inner chamber of described valve body is a streamline structure.
The dish mouth diameter of the water conservancy diversion disc type locating piece 4 of the clamp plate type safety check of above-mentioned band diversion disk is more than or equal to the diameter of spool 1.
Working principle of the present utility model is, the streamline inner chamber of safety check cooperates with the diversion disk of locating piece, form a mild flow channel for liquids, make the liquid and the interior part bump of valve of the valve body of flowing through very little, flow velocity is even and regular, reduce the resistance coefficient of safety check, thereby reduced the hydraulic loss of safety check.
Narrate below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
See figures.1.and.2 and be an embodiment of the present utility model, in the valve body 3 of the clamp plate type safety check of band diversion disk spool 1 is housed, the bearing pin of spool 1 and locating piece are pegged graft, spring 2 is arranged between spool 1 and the locating piece, in order to pressed spool 1, locating piece is connected with valve body 3 one, and described locating piece is a water conservancy diversion disc type locating piece 4, and the diversion disk concave surface of described locating piece is facing to the water intake direction.The inner chamber of described valve body is a streamline structure.
The dish mouth diameter of the water conservancy diversion disc type locating piece 4 of the clamp plate type safety check of above-mentioned band diversion disk equals the diameter of spool 1.
Claims (2)
