Description
Technical field
The utility model relates to the high one-way valve of a kind of sealing.
Background technique
One-way valve is also known as safety check or check valve.For preventing oil stream reverse flow in hydraulic system, or for preventing pressurized air reverse flow in pneumatic system.But one-way valve used in the market have ignored the impulse force of flow of fluid to one-way conduction structure while its unidirectional general character of consideration, and single one-way conduction structure can not meet the sealability of high request.
Model utility content
The purpose of this utility model is the one-way valve providing a kind of sealing high, its structure is simple, one-way conduction good airproof performance, first unidirectional baffle plate and the second unidirectional baffle plate with the use of the sealability not only increasing one-way conduction, and reduce the impulse force of liquid backflow to valve rod, thus effectively improve the usability of one-way valve.
In order to achieve the above object, the technical solution of the utility model is: the one-way valve that a kind of sealing is high, comprise valve body, described valve body comprises water intake, water outlet, described valve body is provided with valve gap, be provided with valve rod in described valve gap, described valve rod bottom is connected with valve disc, and described valve stem tip is connected with hand valve; Offer into water cavity, water outlet cavity, sealing cavity in described valve body respectively, the first unidirectional baffle plate is installed between described water inlet cavity and sealing cavity, the second unidirectional baffle plate is installed between described sealing cavity and water outlet cavity.
Described valve disc bottom is provided with the first sealing plug, the second sealing plug, is provided with sealing gasket between described first sealing plug and the second sealing plug, and the width of described sealing gasket equals the width of the first unidirectional baffle plate.
Described valve body madial wall is separately installed with the first projection, the second projection, the 3rd projection, is provided with the first unidirectional baffle plate between described first projection and the second projection, is provided with the second unidirectional baffle plate between described second projection and the 3rd projection.
Described valve body and the first projection, the second projection, the 3rd projection is integrally manufactured forms.
Be provided with spring between described valve rod and valve disc, described valve rod is connected with valve disc by locating stud.
Between described valve rod and valve gap, seal ring is installed.
Described valve body is connected with valve gap by bolt.
The beneficial effects of the utility model are: the one-way valve that a kind of sealing is high, its structure is simple, one-way conduction good airproof performance, first unidirectional baffle plate and the second unidirectional baffle plate with the use of the sealability not only increasing one-way conduction, and reduce the impulse force of liquid backflow to valve rod, thus effectively improve the usability of one-way valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For the ease of understanding the utility model, below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
The one-way valve that a kind of sealing is high as shown in Figure 1, comprise valve body 1, described valve body 1 comprises water intake 20, water outlet 21, and described valve body 1 is connected with valve gap 2 by bolt 19, be provided with valve rod 3 in described valve gap 2, described valve rod 3 is connected with valve disc 4 by locating stud 22.Between described valve rod 3 and valve disc 4, spring 17 is installed.Described valve rod 3 top is connected with hand valve 5.
Offer respectively into water cavity 6, water outlet cavity 7, sealing cavity 8 in described valve body 1.Described valve body 1 madial wall is separately installed with the first projection 14, second projection 15, the 3rd projection 16, between described first projection 14 and the second projection 15, first unidirectional baffle plate 9 is installed, the second unidirectional baffle plate 10 is installed between described second projection 15 and the 3rd projection 16.Described valve body 1 and the first projection 14, second projection 15, the 3rd projection 16 is integrally manufactured forms.First unidirectional baffle plate 9 is installed between described water inlet cavity 6 and sealing cavity 8, the second unidirectional baffle plate 10 is installed between described sealing cavity 8 and water outlet cavity 7.First unidirectional baffle plate 9 and the second unidirectional baffle plate 10 with the use of the sealability not only increasing one-way conduction, and reduce the impulse force of liquid backflow to valve rod, thus effectively improve the usability of one-way valve.
