Abstract
The utility model relates to a check valve with a flexible valve outward segment, which can be connected to a water outlet of a water pump. The utility model is composed of a body shell 1, a water inlet 2, a support frame 3, a multi-hole limit plate 4, a valve sleeve 5, a water outlet 8, etc., wherein, the shell is a plastic body shell, and the support frame 3 and the valve sleeve 5 which are in the body shell form an umbrella-shaped check member. When the water pump lifts water, the valves are combined, and the water flow is unblocked; when the water pump is stopped and the water flows back, the valve sleeve is deployed, the water flow is blocked, and the impulsive force of the water can be counteracted. Because the shell body is the flexible member which is made of plastic elastic material, the check valve can also replace a flexible rubber joint. The utility model has the advantages of simple structure, one object with multiple functions, reliable performance, low cost, etc.
Description
Technical field: the utility model is a kind of mechanical device, promptly a kind of flexible valve abduction safety check.
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 safety check mostly is simple rigid construction, can not cushion water hammering.Minority has the check valve structure complexity of elastic structure, and 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 a kind of flexible valve abduction safety check, also be by housing, water intake, retaining element in water outlet and the housing constitutes, different is: said retaining element is to be made of flexible flaps Membrane cover and supporting frame, supporting frame is a rigid pipe of installing along the housing axis, two ends are connected on the housing by pole, the valve cover is the sleeve made from flexible material, be enclosed within on the supporting frame, at pump intake on one side, the valve cover closely is connected with supporting frame and seals, the opening of the other end opens under normal pressure and is affixed to the inwall of housing, can produce significantly distortion under uniaxial pressure.
Said housing stage casing is spherical rubber elastomer.
Said supporting frame is an elongate rod.
Said supporting frame is to be the rigid body frame of trident star by the connect transverse section that forms, the long limit of three rectangular laths by separately.
Between said supporting frame and the valve cover, be connected by the spacing band that is rope form.
On the supporting frame of water intake one side, a porous limiting board is housed, after valve is reversed current and washes open, during its outer surface contact limiting board, be the maximum position of valve orifice.
The safety check that adopts such scheme to make is contained on the water outlet of water pump, and when the water pump water lift, valve cover outer surface is subjected to the impact of water and is attached on the supporting frame, thereby current are unimpeded.When the water pump stall, during the current inflection, the big end opening of valve cover opens, blocking channel, and anti-backflow produces certain tensile buckling buffered water hammering blow simultaneously.
Accompanying drawing is introduced: Fig. 1 is a kind of plan view of mode of execution, and Fig. 2 is its left view.Fig. 3 is second kind of retaining element plan view in the mode of execution, and Fig. 4 is its left view, and Fig. 5 is its plan view.
Among the figure as seen: housing 1, water intake 2, supporting frame 3, porous limiting board 4, valve cover 5, spacingly be with 6, support 7, water outlet 8, trident star supporting frame 9.
Mode of execution:
First kind: as seen from Figure 1, this non-return valve housing 1 two ends are provided with water intake 2 and water outlet 8, end face all has the flange plate that usefulness is installed, and a umbrella retaining element is arranged in the housing, its supporting frame shape such as umbrella bar, top valve shell-like such as umbrella cover, the umbrella bar is installed along the housing axis, and two ends are supported on the housing by support 7 or porous limiting board 4, at water intake 2 one ends, the valve cover links to each other with supporting frame and seals, and the other end valve cover is opening-like.During for the water pump water lift, under the impact of current, valve is adjacent to supporting frame, and pipeline is open-minded, and when the inflection of termination of pumping current, the valve cover is washed open, and the valve abduction is close to inner walls, and current are obstructed.Along with the tensile buckling of valve, water hammering is alleviated counteracting.
In order to prevent the valve hyper-abduction, spacing be with 6 valve covers to be pulled on the supporting frame in the inboard of valve by several, the abduction amplitude of restriction valve.Also a porous limiting board 9 or spacing net can be set on the supporting frame of water intake one side, when being deployed into the position of porous limiting board 9 under the impact of valve at reverse flow, turn over after can not continuing again.
Because housing adopts flexible material making such as rubber, the distortion of big spoke degree can be arranged after the installation, thereby can replace the elastomer connector on original exit of pump pipeline section.
Second kind; Housing is identical with first kind of mode of execution, and just the supporting frame of the inside has changed shape, the retaining element so Fig. 3, Fig. 4, Fig. 5 have only drawn, and omitted the view of housing.
As shown in the figure: the supporting frame of valve cover is to be docked by a limit separately by three laths to form, angle is 120 ° between per two battens, thereby the valve cover three parts have been divided into, form three valve capsules, when valve and fashionable, being close on the plate face of supporting frame, when opening, also is outwards to be affixed to inner walls.The working state of the valve of this mode is more reliable and more stable.
