Abstract
The utility model discloses an energy saving check valve device, which comprises a valve body with two ends respectively provided with a water inlet and a water outlet. A valve flap is hinged inside the valve body. The energy saving check valve device is characterized in that a hydraulic cylinder is fixedly connected on the lower part of the valve body; a piston is equipped inside the hydraulic cylinder; a piston rod inserted into the valve body and capable of propping up the valve flap is connected on the piston; a spring is sleeved on a piston rod part located inside the hydraulic cylinder; a communicating pipe is connected on the lower end of the hydraulic cylinder; and the other end of the communicating pipe is communicating with a water intake pipeline of the valve body water inlet. The check valve device in the utility model is advantageous in that the fluid entering the valve body no longer needs to overcome the resistance of the valve flap for circulation due to the fact that the hydraulic cylinder fixedly connected on the lower part of the valve body and communicating with the water intake pipeline of the valve body water inlet enables the fluid entering the hydraulic cylinder to push the piston rod and make the piston rod rise through the fluid pressure so as to make the opened valve flap propped; the resistance to the fluid is low; the impact on the tonnage is insignificant; the pipeline loss of a discharge pipe line can be reduced; and the water pump efficiency is improved.
Description
Technical field
The utility model is particularly related to a kind of energy-conservation check vavle device.
Background technique
In discharge pipe line, the fluid when preventing termination of pumping or sudden power in the pipeline reflux suddenly and " water hammer " that form equipment is damaged, on the pump outlet pipeline, safety check is installed usually.Common safety check has rotary-open type and Lift check valve, behind pump working, when fluid flow reaches rated pressure, open flap by hydrodynamic pressure, but can produce certain resistance by convection cell after flap is opened, water displacement is affected, but also consumed energy.Though therefore existing safety check has played the protective action to equipment, also increased the line loss of discharge pipe line, reduced the efficient of water pump.
Summary of the invention
The resistance that the technical problems to be solved in the utility model provides a kind of convection cell generation is little, and is little to the water displacement influence, can reduce the line loss of discharge pipe line, improves the energy-conservation check vavle device of pump efficiency.
Technical solution of the present utility model is: it has two ends to be respectively equipped with the valve body of water intake and water outlet, in valve body, be hinged with flap, its special way is: be connected with oil hydraulic cylinder below valve body, in oil hydraulic cylinder, be provided with piston, on piston, be connected with the piston rod that is inserted in the valve body and flap can be propped up, on piston rod, be positioned at oil hydraulic cylinder and be with spring, be connected with connecting tube in the oil hydraulic cylinder lower end, connecting tube the other end be communicated with the inlet pipeline that is connected the valve inleting water mouth.
Above-mentioned energy-conservation check vavle device, the insert division of corresponding piston rod is provided with copper sheathing on valve body, is provided with seal ring in copper sheathing, to realize sealing.
The utility model has the advantages that: owing to below valve body, be connected with the oil hydraulic cylinder that is communicated with the inlet pipeline that is connected the valve inleting water mouth, promoting piston rod by the hydrodynamic pressure that enters oil hydraulic cylinder rises and the flap of opening can be propped up, make the fluid that enters valve body need not to overcome the resistance of flap and circulate, therefore the resistance of convection cell generation is little, little to the water displacement influence, can reduce the line loss of discharge pipe line, improve the efficient of water pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: valve body 1, water intake 101, water outlet 102, valve gap 2, flap 3, piston rod 4, copper sheathing 5, seal ring 6, spring 7, piston 8, oil hydraulic cylinder 9, connecting tube 10, inlet pipeline 11.
Embodiment
As shown in the figure, this energy-conservation check vavle device has a valve body 1, be respectively equipped with water intake 101 and water outlet 102 at valve body 1 two ends, be fixed with valve gap 2 in valve body 1 upper end, being hinged with in valve body 1 can be with the flap 3 of valve inleting water mouth 101 shutoff, be connected with oil hydraulic cylinder 9 at valve body 1 below by bolt, in oil hydraulic cylinder 9, be provided with piston 8, the center is connected with the piston rod 4 that the upper end is inserted in the valve body 1 and flap 3 can be propped up on piston 8, the insert division of corresponding piston rod 4 is provided with copper sheathing 5 on valve body 1, in copper sheathing 5, be provided with seal ring 6, on piston rod 4, be positioned at oil hydraulic cylinder 9 and be with spring 7.Be connected with connecting tube 10 in oil hydraulic cylinder 9 lower ends, connecting tube 10 the other end be communicated with the inlet pipeline 11 that is connected valve inleting water mouth 101.
During installation, valve inleting water mouth 101 and pump outlet are communicated with by described inlet pipeline 11.During pump working, when the pressure in the inlet pipeline 11 reaches rating value, flap 3 is washed open, liquid is discharged by valve body 1, at this moment the liquid in the pipeline is under the effect of pressure, by entering connecting tube 10 in the oil hydraulic cylinder 9, promote piston 8 and piston rod 4 rises, withstand flap 3 and make it reach the maximum rising space after piston rod 4 rises.When termination of pumping or have a power failure suddenly, the pressure moment in the inlet pipeline 11 is zero, and the pressure in the oil hydraulic cylinder 9 is by connecting tube 10 abrupt release, and under spring 7 effects, piston 8 and piston rod 4 fall after rise, flap 3 by gravity automatically upset valve inleting water mouth 101 is closed.
Claims (2)
1. energy-conservation check vavle device, comprise that two ends are respectively equipped with the valve body of water intake and water outlet, in valve body, be hinged with flap, it is characterized in that: below valve body, be connected with oil hydraulic cylinder, in oil hydraulic cylinder, be provided with piston, on piston, be connected with the piston rod that is inserted in the valve body and flap can be propped up, on piston rod, be positioned at oil hydraulic cylinder and be with spring, be connected with connecting tube in the oil hydraulic cylinder lower end, connecting tube the other end be communicated with the inlet pipeline that is connected the valve inleting water mouth.
