Abstract

The utility model discloses an anti-high-pressure flow-stabilization type micro-resistance check valve. The anti-high-pressure flow-stabilization type micro-resistance check valve comprises a valve body, two ends of the valve body are respectively a water-inlet and a water-outlet, a valve plate which is horizontally arranged inside the valve body is movably hinged inside an inner cavity of the valve body, a supporting bar is arranged on an inner wall of the valve body outside the valve plate, and a spring is arranged outside the supporting bar in sleeved mode. A rubber buffer pad is arranged on an inner side wall of the valve plate in bonding mode, a stop block is fixed on an inner wall above the valve body, and the top end of the stop block is arranged on an outer side wall of the valve plate in abutting mode. A flow-stabilization plate is arranged on the water-outlet of the valve body, a plurality of mesh-shaped holes are arranged on the flow-stabilization plate, and buffer pieces are arranged inside the mesh-shaped holes. The flow-stabilization type micro-resistance check valve can be arranged in a pipeline or on an outlet portion of a pump and used in a safety device which prevents inverse rotation of the pump because backflow of media produces a water hammer to impact the pump in the halt process of the pump. The flow-stabilization type micro-resistance check valve has the advantages of being stable and reliable in sealing properties, wear-resisting, long in service life, stable in operation, and free of vibration.

Description

The little resistance safety check of a kind of anti-high pressure constant-current type
Technical field
The utility model relates to the opening/shutting valve class, specifically is the little resistance safety check of a kind of anti-high pressure constant-current type.
Background technique
At present; It is of all kinds that the valve arrangement form is returned in the little prevention of anti-high pressure constant-current type; The form that the open-close type safety check is arranged also has external cushion dashpot form, but the buffering when all just needing a kind of liquid to accomplish valve closing; Eliminate destructive water hammer, to ensure the property safe and reliable to operation of water supply line facility.But often because the leakage or the obstruction of hydraulic pipe line lose due function.
The model utility content
The purpose of the utility model provides the little resistance safety check of a kind of anti-high pressure constant-current type; Be installed in the pipeline or the delivery side of pump place; Be used for preventing when pump is shut down that the medium refluence from producing the safety installations of impact of water hammer pump reversing; Sealability is reliable and stable, wear-resistant, long service life, operate steadily, friction.
The technological scheme of the utility model is following:
The little resistance safety check of a kind of anti-high pressure constant-current type includes valve body, and two ends of valve body is respectively water intake, water outlet; Be rotatablely hinged with the valve plate that is horizontally placed in the valve body in the inner chamber of valve body, the valve interior wall in the valve plate outside is provided with strut, and strut is set with spring outward; Be bonded with rubber buffer on the madial wall of described valve plate, the inwall of valve body top is fixed with chock, and the top overhead of chock is in the outer side wall of valve plate; The water outlet of valve body is provided with stabilier; Be distributed with a plurality of reticulated cell on the stabilier, be provided with buffer substrate tablet in the hole of reticulated cell, the water outlet internal fixation of valve body is combined with dsah-pot; Be distributed with pawl on the dsah-pot inwall, the rear end of dsah-pot is provided with tapered transition.
The top of described chock is provided with soft cushion block.
The utility model is installed in the pipeline or the delivery side of pump place; Be used for preventing when pump is shut down that the medium refluence from producing the safety installations of impact of water hammer pump reversing, it is big to have the light open degree of flap, and power savings is remarkable; Fluid resistance is little; Sealability is reliable and stable, wear-resistant, long service life, operate steadily, friction, be applicable in the system pipelines such as plumbing, fire-fighting, HVAC or pump outlet prevents that medium from flowing backwards and produces water hammer pipeline or pump are produced harm.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, the little resistance safety check of a kind of anti-high pressure constant-current type includes valve body 1; The two ends of valve body 1 are respectively water intake 2, water outlet 3, are rotatablely hinged with the valve plate 4 that is horizontally placed in the valve body in the inner chamber of valve body 1, and the valve interior wall in valve plate 4 outsides is provided with strut 5; Be set with spring 6 outside the strut 5, be bonded with rubber buffer 7 on the madial wall of valve plate, the inwall of valve body top is fixed with chock 8; The top overhead of chock 8 is in the outer side wall of valve plate, and the water outlet of valve body is provided with stabilier 9, is distributed with a plurality of reticulated cell 10 on the stabilier 9; Be provided with buffer substrate tablet 11 in the hole of reticulated cell 10, the water outlet internal fixation of valve body 1 is combined with dsah-pot 12, is distributed with pawl 13 on dsah-pot 12 inwalls; The rear end of dsah-pot 12 is provided with tapered transition 14, and the top of chock is provided with soft cushion block.
