Abstract
An electromagnetic check valve comprises a valve body, a valve bottom, a valve cover and a valve plate. A valve seat is fixed at the bottom end of the valve body, the valve cover is fixed at the top end of the valve body, the valve plate is connected with the valve cover through a fixing shaft, an electromagnetic piece is embedded in the upper end of the valve body, an electromagnetic rod is mounted in the valve plate, a controller is fixed at the top end of the valve cover, and leads are wound around both the electromagnetic rod and the electromagnetic piece and connected with the controller. The electromagnetic check valve is characterized in that a torsion spring is replaced by the electromagnetic rod and the electromagnetic piece, so that service life is prolonged, and electromagnetic check valve is suitable for pipelines various in fluid pressure.
Description
Technical field
The utility model relates to valve field, particularly a kind of safety check.
Background technique
Safety check is a kind of valve that is used for limiting flow direction.The structural design of existing safety check and principle are very reasonable, but its reposition element adopts twisting spring more, use for a long time rear spring to understand lost its bounce and affect keying effect; Because the pressure of some pipeline inner fluid is too small, be difficult to wash open the valve plate that is provided with torque spring, impact is normally used simultaneously.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and has designed a kind of solenoid check valve.Specific design scheme is:
A kind of solenoid check valve, at the bottom of comprising valve body, valve, valve gap, valve plate, at the bottom of the bottom of described valve body is fixed with valve, the top of described valve body is fixed with valve gap, and described valve plate is connected with described valve gap by stationary axle, and described valve body upper end is embedded with electromagnetic plate, in described valve plate, electromagnetic wand is installed, the top of described valve gap is fixed with controller, and the surrounding of described electromagnetic wand, electromagnetic plate is all wound with wire, and described wire is connected with described controller.
The bottom of described valve body is provided with valve plug.
Between described valve gap and valve body, be filled with seal ring.
Described wire is wound in described electromagnetic plate surrounding along clockwise direction.
Described wire is wound in described electromagnetic wand surrounding in the counterclockwise direction.
The solenoid check valve obtaining by above-mentioned design proposal of the present utility model, its beneficial effect is:
Described electromagnetic wand is contrary with the winding direction of electromagnetic plate upper conductor, when producing contrary electromagnetic field after energising, thereby described valve plate and valve body upper end are repelled mutually, described valve plate and valve body upper end are more approaching, its repulsion is larger, can replace the effect of torque spring completely.
Described controller can regulate the electric current in described wire, thereby reaches the effect of controlling repulsion between described electromagnetic wand and electromagnetic plate, guarantees that solenoid check valve adapts to the pipeline use of various hydrodynamic pressures.

Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
Fig. 1 is the structural representation of solenoid check valve described in the utility model while closing, and Fig. 2 is the structural representation of solenoid check valve described in the utility model while opening, Fig. 3 is the structural representation of valve plate described in the utility model, as Fig. 1, Fig. 2, shown in Fig. 3, a kind of solenoid check valve, comprise valve body 1, at the bottom of valve 2, valve gap 3, valve plate 4, the bottom of described valve body 1 is fixed with at the bottom of valve 2, the top of described valve body 1 is fixed with valve gap 3, described valve plate 4 is connected with described valve gap 3 by stationary axle 5, described valve body 1 upper end is embedded with electromagnetic plate 6, in described valve plate 4, electromagnetic wand 7 is installed, the top of described valve gap 3 is fixed with controller 8, described electromagnetic wand 7, the surrounding of electromagnetic plate 6 is all wound with wire 9, described wire 9 is connected with described controller 8.
The bottom of described valve body 1 is provided with valve plug 10.
Between described valve gap 3 and valve body 1, be filled with seal ring 11.
Described wire 9 is wound in described electromagnetic plate 6 surroundings along clockwise direction.
Described wire 9 is wound in described electromagnetic wand 7 surroundings in the counterclockwise direction.
During use, by controller 8, regulate the electric current in described wire 9, described electromagnetic wand 7, electromagnetic plate 6 surroundings are because the wire 9 that is wound with belt current produces magnetic force, thereby make described valve plate 4 and the top of described valve body 1 produce repulsion, reach the effect of torque spring in conventional check valves.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some variations that wherein some part may be made, within belonging to protection domain of the present utility model.
