Description
Technical field
The utility model relates to a kind of shut-off valve.
Background technique
Along with industrialized development, shut-off valve is used widely, along with improving constantly of required precision, requirement for shut-off valve also improves constantly, all there is the problems such as sealing is not high, shutoff property is low in commercially used shut-off valve at present, all can not solve the appearance that one-way flow prevents backward flow problem simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of shut-off valve, and its structure is simple, easy for installation, sealing is high, and shutoff property is high, can not only realize the one-way flow of shut-off valve, and effectively can prevent the appearance of refluence phenomenon, substantially increase the practicability of shut-off valve.
In order to achieve the above object, the technical solution of the utility model is: a kind of shut-off valve, comprises valve body, described valve body comprises water intake, water outlet, water inlet cavity, water outlet cavity, be provided with valve rod in described valve body, be provided with valve gap in described water inlet cavity, described valve rod is connected with valve gap; Described valve gap bottom is separately installed with the first sealing plug, the second sealing plug, valve gap between described first sealing plug and the second sealing plug is provided with sealing gasket, between described water inlet cavity and water outlet cavity, unidirectional guide plate is installed, described unidirectional guide plate offers with sealing gasket with the use of groove.
Between described valve rod and valve gap, spring is installed, and described valve rod is connected with valve gap by locating stud.
Be separately installed with the first filtering baffle, the second filtering baffle in described water outlet cavity, and in valve body between described first filtering baffle and the second filtering baffle, filter screen be installed.
Be separately installed with between described valve rod and valve body evagination seal ring, with evagination seal ring with the use of groove seal ring.
Described valve body is provided with dust cap.
The beneficial effects of the utility model are: a kind of shut-off valve, and its structure is simple, easy for installation, sealing is high, and shutoff property is high, can not only realize the one-way flow of shut-off valve, and effectively can prevent the appearance of refluence phenomenon, substantially increase the practicability of shut-off 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.
A shut-off valve as shown in Figure 1, comprises valve body 1, and described valve body 1 comprises water intake 2, water outlet 3, water inlet cavity 4, water outlet cavity 5, and be provided with valve rod 6 in described valve body 1, be provided with valve gap 7 in described water inlet cavity 4, described valve rod 6 is connected with valve gap 7.Between described valve rod 6 and valve gap 7, spring 13 is installed, and described valve rod 6 is connected with valve gap 7 by locating stud 14.Described valve body 1 is provided with dust cap 18.
Described valve gap 7 bottom is separately installed with the first sealing plug 9, second sealing plug 10, valve gap 7 between described first sealing plug 9 and the second sealing plug 10 is provided with sealing gasket 11, between described water inlet cavity 4 and water outlet cavity 5, unidirectional guide plate 8 is installed, described unidirectional guide plate 8 offers with sealing gasket 11 with the use of groove 12.The setting of unidirectional guide plate 8 can not only make shut-off valve one-way flow, and can effectively prevent liquid from flowing backwards.
Be separately installed with the first filtering baffle 19, second filtering baffle 15 in described water outlet cavity 5, and in valve body 1 between described first filtering baffle 19 and the second filtering baffle 15, filter screen 16 be installed.First filtering baffle 19, second filtering baffle 15 and filter screen 16 with the use of the filtering effect that improve shut-off valve.
Be separately installed with between described valve rod 6 and valve body 1 evagination seal ring 17, with evagination seal ring 17 with the use of groove seal ring 20.Evagination seal ring 17 and groove seal ring 20 with the use of the sealing that improve between valve rod 6 and valve body 1.
A kind of shut-off valve of the present embodiment, its structure is simple, and easy for installation, sealing is high, and shutoff property is high, can not only realize the one-way flow of shut-off valve, and effectively can prevent the appearance of refluence phenomenon, substantially increase the practicability of shut-off valve.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection domain of the present utility model.
