Abstract
The invention discloses a novel check valve which comprises a vale body, a valve plate and a spring. The valve plate and the spring are arranged inside the valve body. One end of the spring is fixed on the central position of the valve plate. The valve body is in a trumpet shape, and contracts towards a water inlet end. A baffle is arranged at a water outlet end of the valve body. The other end of the spring is fixed on the central position of the baffle. The baffle is a round plate, and the diameter of the baffle is identical to the inner diameter of a water inlet of the valve body. Water outlet holes are formed in the positions, far away from the spring, of the baffle. The water inlet and the water outlet of the check valve can be accurately distinguished even though light is weak, and the novel check valve is long in service life, can meet the branch requirements of the water outlet, and is convenient to use.
Description
Technical field
The present invention relates to a kind of valving, especially a kind of one-way valve that is used for the control media one-way flow belongs to valve technology field.
Background technique
In pipe-line system, in order to prevent the medium reverse flow in the pipeline, all one-way valve can be installed.Usually one-way valve all is by being arranged on one-way flow that valve plate in the valve body and spring realize medium, when one-way valve is installed, pay particular attention to the media flow direction, need to make the direction of arrow of indicating on medium proper flow direction and the valve body consistent, otherwise not only can block the proper flow of medium, also can damage one-way valve.But the bright indicating arrow of one-way valve valve body subscript is generally all smaller, is not easy to distinguish, and if under the very weak environment of dark or light, and just difficulty relatively of one-way valve is installed.For this reason, the people in the industry proposes to apply at valve inleting water mouth place one deck fluorescent material, to overcome the inlet/outlet of distinguishing one-way valve under the environment a little less than the light, avoids setup error.But the fluorescent material of coating can only can be seen under the very weak environment of light, and after use a period of time, coating layer has just slowly disappeared, and working life is not long.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposes a kind of ratio and has been easier to distinguish inlet/outlet, and the Novel check valve of long service life.
Technical solution of the present invention is achieved in that a kind of Novel check valve, comprises valve body, valve plate and spring; Described valve plate and spring all are positioned at valve inner; One end of described spring is fixed on the central position of valve plate; Described valve body is horn-like, and shrinks to inlet end; The water outlet end of described valve body is provided with baffle plate; The other end of described spring is fixed on the central position of baffle plate; Described baffle plate is circular plate, and its diameter is identical with the internal diameter of the water intake of valve body; Away from the position of spring, have osculum on the described baffle plate.
Preferably, described osculum is two, lays respectively at the both sides of spring.
Preferably, described water intake and osculum place are equipped with the flange plate of connecting tube.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Novel check valve of the present invention, just can accurately distinguish the inlet/outlet of one-way valve by the contraction mouth of horn-like valve body, even in the situation that light is very weak, also can be by touching horn-like valve body, distinguish very like a cork the inlet/outlet of knowing one-way valve, and its long service life; Two osculums that are provided with at the baffle plate place do not need to increase other conversion parts, just can satisfy branch's requirement of water outlet, and are very easy to use.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing l is the stereogram of Novel check valve of the present invention;
Accompanying drawing 2 is the stereogram of another angle of Novel check valve of the present invention;
Accompanying drawing 3 is the axial sectional view of Novel check valve of the present invention;
Wherein: 1, valve body; 2, valve plate; 3, spring; 4, baffle plate; 5, osculum; 6, flange plate; 7, water intake.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of Novel check valve of the present invention such as accompanying drawing 1,2,3, comprise valve body 1, valve plate 2 and spring 3; Described valve plate 2 and spring 3 all are positioned at valve body 1 inside; One end of described spring 3 is fixed on the central position of valve plate 2; Described valve body 1 is horn-like, and shrinks to water intake 7 ends; The water outlet end of described valve body 1 is provided with baffle plate 4; The other end of described spring 3 is fixed on the central position of baffle plate 4; Described baffle plate 4 is circular plate, and its diameter is identical with the internal diameter of the water intake 7 of valve body 1; Away from the position of spring 3, have osculum 5 on the described baffle plate 4; Described osculum 5 is two, lays respectively at the both sides of spring 3; Described water intake 7 and osculum 5 places are equipped with the flange plate 6 of connecting tube.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Novel check valve of the present invention, just can accurately distinguish the inlet/outlet of one-way valve by the contraction mouth of horn-like valve body, even in the situation that light is very weak, also can be by touching horn-like valve body, distinguish very like a cork the inlet/outlet of knowing one-way valve, and its long service life; Two osculums that are provided with at the baffle plate place do not need to increase other conversion parts, just can satisfy branch's requirement of water outlet, and are very easy to use.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is 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.
