Abstract
The invention discloses a minitype low-pressure self-locking check valve which comprises a pump cap, a valve gate and a valve seat. A pump casing is arranged on the inner side of the lower portion of the valve gate. The valve gate and the pump casing are fixed on the valve seat through the pump cap. The upper portion of the valve gate is set to be center-shaped. According to the minitype low-pressure self-locking check valve, due to the facts that the upper portion of the valve gate is set to be center-shaped, liquid can only flow through the valve gate from one direction, and is incapable of flowing through the valve gate from a reverse direction, and prevention of backflow of the liquid can be achieved. The minitype low-pressure self-locking check valve has the advantages of being simple in structure, small in amount of parts, and low in cost.
Description
Technical field
The present invention relates to a kind of improvement of safety check, refer in particular to a kind of simple in structure, Miniature low voltage self-locking safety check that cost is low.
Background technique
Safety check refers to rely on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards, and claims again check valve, one-way valve, reflux valve and back pressure valve.Safety check belongs to a kind of automatic valve, and its Main Function is to prevent that medium from flowing backwards, preventing pump and drive motor counter-rotating, and the releasing of vessel media.Safety check also can be used for may rising to the auxiliary system of pressing over system to wherein pressure to be provided on the pipeline of supply.Safety check mainly can be divided into Swing check valve (according to the center of gravity rotation) and Lift check valve (moving along axis).The complex structure of safety check of the prior art, component are many, processing, installation complexity, cost is high.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of simple in structure, Miniature low voltage self-locking safety check that cost is low.
For achieving the above object, the technical solution used in the present invention is: a kind of Miniature low voltage self-locking safety check comprises pump cap, valve, valve seat; The lower inside of described valve is provided with pump block; Described pump cap is fixed on valve, pump block on valve seat; Top shape is arranged on the top of described valve.
Preferably, described pump block screw thread is fixed on the lower inside of valve.
Preferably, the top of described valve is arranged to coniform.
Preferably, tip-angled shape is arranged on the top of described valve.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described Miniature low voltage self-locking of the present invention program safety check is because top shape is arranged on the top of described valve; Liquid can only be from the direction valve of flowing through; Valve can't be flow through in the other direction, thereby liquid backflow can be realized preventing; The present invention is simple in structure, component are few, and cost is low.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 2 is the plan view of accompanying drawing 1;
Accompanying drawing 3 is the sectional view of the liquid state of rest of Miniature low voltage self-locking safety check of the present invention;
Accompanying drawing 4 is the plan view of accompanying drawing 3;
Accompanying drawing 5 is the sectional view of the liquid backflow state of Miniature low voltage self-locking safety check of the present invention;
Accompanying drawing 6 is the plan view of accompanying drawing 5;
Wherein: 1, pump cap; 2, valve; 3, pump block; 4, valve seat.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1-6 a kind of Miniature low voltage self-locking safety check of the present invention comprises pump cap 1, valve 2, valve seat 4; The lower inside of described valve 2 is provided with pump block 3; Described pump block 3 screw threads are fixed on the lower inside of valve 2; Described pump cap 1 is fixed on valve 2, pump block 3 on valve seat 4; Top shape is arranged on the top of described valve 2; The top of valve described in the present embodiment 2 is arranged to coniform.Certainly, tip-angled shape also can be arranged in the top of described valve.
Accompanying drawing 1-2 is depicted as the liquid discharge stream mode of described Miniature low voltage self-locking safety check, and liquid enters from water intake, after backing down valve 2, flows out from water outlet.
Accompanying drawing 3-4 is depicted as the liquid state of rest of described Miniature low voltage self-locking safety check, at this moment, and valve 2 autoshutdowns.
Accompanying drawing 5-6 is depicted as the liquid backflow state of described Miniature low voltage self-locking safety check, and liquid enters from water outlet, gives the top pressurization of valve 2, and because the top of valve 2 is top shape, it is tighter that the pressure of liquid more closes valve 2, thereby realize the backflow of prevention liquid.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described Miniature low voltage self-locking of the present invention program safety check is because top shape is arranged on the top of described valve; Liquid can only be from the direction valve of flowing through; Valve can't be flow through in the other direction, thereby liquid backflow can be realized preventing; The present invention is simple in structure, component are few, and cost is low.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
