Abstract
The utility model discloses a water backflow preventing device of a water supply pipeline to solve the problem that no suitable water backflow preventing device is arranged on certain branched pipes small in water supply flow currently. The water backflow preventing device comprises a water supply pipe, a section of a shrinking pipe small in diameter is serially connected on the water supply pipe, one end of a retaining plate is hinged on the pipe wall of an outlet of the shrinking pipe while the other end of the same is connected with the inner wall of the shrinking pipe through a spring, and a position where the retaining plate contacts with the outlet of the shrinking pipe is sealed by mounting a rubber sealing ring. By the water backflow preventing device, the retaining plate can be enabled to be automatically closed through the spring according to changes of water supply pressure to achieve the object of automatically cutting off water backflow; the rubber sealing ring can play a great role in sealing, so that the water backflow preventing device is good in water backflow preventing effect.
Description
Technical field
The utility model relates to the anti-water recovery apparatus of a kind of water supply line.
Background technique
In water supply process, frequent generation is cut off the water supply suddenly or water flow pressure diminishes, and at this moment backwater phenomenon easily occurs, and pipeline generation backwater not only causes downstream water supply can not be guaranteed, and easily upstream motor or valve etc. is impacted.Conventional anti-backwater Disposal Measures is to install back water valve at present, adopts the mode of valve to carry out anti-non-return water, and this device easily adopts in large-scale water supply line, and the arm less to some water supply flows operates inconvenience.
Summary of the invention
The purpose of this utility model is to overcome prior art defect, provides a kind of water supply line anti-water recovery apparatus.
The technical solution of the utility model is achieved in that the anti-water recovery apparatus of a kind of water supply line, comprise water pipe, it is, the one section of diameter of contacting on water pipe is less dwindles pipe, baffle plate one end is hinged on and dwindles on pipe outlet tube wall, the other end by spring with dwindle inner tube wall and be connected, baffle plate with dwindle pipe outlet contacting point rubber seal ring sealing be installed.
Preferably, baffle plate upper end is hinged on and dwindles on pipe outlet tube wall, lower end by spring with dwindle inner tube wall and be connected.
The utility model can be according to the variation of pressure of supply water, by spring, make baffle plate automatically closed, reaches the object that automatic cut-out current reflux, and rubber seal ring can play good seal action, and anti-backwater is effective.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1-water pipe; 2-dwindles pipe; 3-baffle plate; 4-spring.
Embodiment
Below in conjunction with accompanying drawing, be further described:
As shown in Figure 1, the anti-water recovery apparatus of water supply line, comprises water pipe 1, and one section of less the dwindling of diameter of contacting on water pipe 1 manages 2, baffle plate 3 upper ends are hinged on and dwindle on pipe 2 outlet tube walls, lower end by spring 4 with dwindle pipe 2 inwalls be connected, more laborsaving, spring 4 resilience effects are better, baffle plate 3 inner rings are circular steel plate, periphery is equipped with ring of silicone rubber,sealing, dwindles on pipe 2 outlet circumference and is also equipped with ring of silicone rubber,sealing, makes baffle plate 3 and dwindle pipe 2 outlet contacting points to form excellent sealing.
When normal water supply, hydraulic pressure can be washed baffle plate 3 open, current normal water supply; When pressure of supply water is too small, the pulling force of spring 4 will make baffle plate 3 close, and cut off and supply water; When there is backwater, pressure of return water will make baffle plate 3 close, and backwater cannot be refluxed.
Claims (2)
1. the anti-water recovery apparatus of water supply line, comprise water pipe, it is characterized in that: the one section of diameter of contacting on water pipe is less dwindles pipe, baffle plate one end is hinged on and dwindles on pipe outlet tube wall, the other end by spring with dwindle inner tube wall and be connected, baffle plate with dwindle pipe outlet contacting point rubber seal ring sealing be installed.
2. the anti-water recovery apparatus of a kind of water supply line according to claim 1, is characterized in that: baffle plate upper end is hinged on and dwindles on pipe outlet tube wall, lower end by spring with dwindle inner tube wall and be connected.
