Abstract
The utility model relates to a check valve with a flexible inward valve. The utility model is composed of a shell 1, a water inlet 2, a water outlet 3, a valve 4 in the shell, a spacing strip 5, etc., wherein, the majority edge of the valve is fixed on the inner wall of the shell, a valve pocket with an opening is formed, and the opening of the valve pocket is toward one side of the water outlet 3. The check valve is connected with a water pump; when the water pump lifts water, the valve is closely contacted with the inner wall of the shell, and the water flow is unblocked. When the water pump is stopped and the water flows back, the valve is opened to close a passage and alleviate shock. In addition, because the shell is a soft flexible body, a rubber joint can be replaced, and the length of an outlet pipe segment of the water pump can be shortened.
Description
Technical field: the utility model is a kind of mechanical device, exhibition safety check in promptly a kind of flexible valve.
Background technique: on the outlet pipe section of water pump, need to install and to prevent the safety check that flows backwards and the elastomer connector of flexible.And existing check valve structure complexity, volume is bigger, and price is higher.Existing elastomer connector acts on singlely, has increased the length of exit of pump pipeline section.
Summary of the invention: the purpose of this utility model is that a kind of water hammer that both can prevent of development takes place, and can replace elastomer connector again, and is simply light, the safety check that cost is lower.Above-mentioned purpose is realized by following technological scheme: develop exhibition safety check in a kind of flexible valve, this safety check also is to be made of housing, water intake, water outlet, retaining element etc., different is: said non-return valve housing is a kind of flexible elastic shell, the inwall of housing is provided with the valve capsule that is made of flexible valve, valve capsule one end is Nang Kou, except that Nang Kou, the remaining edge of flexible valve all is connected mutually in inner walls, and capsule mouth direction is towards safety check water outlet one end.
Said housing middle part is spherical in shape, uniform three valve capsules on the inner walls.
The inboard of said valve capsule is provided with spacing band, and an end of spacing band is connected on the valve, and the other end is connected on the inner walls.
Said housing is the flexible elastic shell of being made by rubber.
The safety check that adopts such scheme to make, simple in structure, cheap.When pump working, under the impact of current, valve is attached on the inwall of safety check, and resistance is very little, and current are unimpeded.When the water pump stall, when the water in the water pipe refluxed, valve Nang Kou opened, exhibition in the valve and block passage, and just water can not reflux.Simultaneously, valve can stretch significantly and produce certain buffer function, offsets the impact of water hammer.In addition,, can replace existing elastomer connector, reduce the connected element of exit of pump pipeline section because the non-return valve housing is flexible.
Description of drawings: Fig. 1 is a kind of embodiment's a plan view, and Fig. 2 is its left view.
Mode of execution: as shown in the figure, this safety check is by housing 1, water intake 2, water outlet 3, valve 4, spacingly is with 5 to constitute.All be provided with the flange plate that usefulness is installed on the water intake 2 of housing and the end face of water outlet 3.The housing middle part is spherical, and inner walls is provided with three valves 4, and valve 4 is made for soft resilient material, its shape such as petal, its most of edge is connected on the inwall of housing, forms a valve capsule that opening is arranged, and opening direction is towards safety check water outlet 3 one sides.In valve capsule inboard, be provided with that one or several rope form elasticity is spacing is with 5, the spacing end of being with connects inner walls, and the other end is connected on the valve, during use, the water intake 2 of this safety check is connected on the pump outlet, and the back connects water pipe.When the water pump water lift, the pressure of current can make the valve of three flexibilities be close on the safety check inner walls, and current are unimpeded.When water pump stall or rotating speed were very low, three valve capsules were washed in the current inflection open.Valve abduction overlap joint has stopped up passage, withstands current.Because valve has elasticity preferably, can be out of shape stretching under water impact, thereby offset the pressure of water hammer, guaranteed the stable and safety of equipment.
In order to prevent that valve from excessively stretching, in the valve capsule, be provided with and spacingly be with 5, spacing band is rope form, and an end is connected on the inner walls, and the other end is connected on the valve, particularly on the opening edge of valve.Spacing band elasticity is less, when valve is expanded to certain position, will hold by limited band, is not turned over or damages and can not dash.
