Abstract
The utility model discloses an energy-saving check valve device which comprises a valve body; a valve clack is articulated in the valve body; the energy-saving check valve device is characterized in that a hydraulic cylinder is fixedly connected on the valve body and is internally provided with a piston; a clamping hook which is inserted into the valve body and can hook the valve clack is connected below the piston; a spring which is arranged in the hydraulic cylinder is arranged on the piston; a communicating pipe is connected at the lower end of the hydraulic cylinder; and the other end of the communicating pipe is communicated with a water inlet pipeline which is connected with a water inlet of the valve body. The energy-saving check valve device has the advantages that the hydraulic cylinder which is communicated with the water inlet pipeline connected with the water inlet of the valve body is fixedly connected on the valve body; the piston is pushed by the pressure of fluid entering the hydraulic cylinder to hook the opened valve clack, so that the fluid entering the valve body can circulate without overcoming the resistance of the valve clack; therefore, no resistance is generated on the fluid, the water discharge is not influenced, the pipeline loss of a discharge pipeline is eliminated, and the efficiency of a water pump is improved.
Description
Technical field
The utility model is particularly related to a kind of energy-conservation check valve 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, check valve is installed usually.Common check valve has two kinds of rotary-open type and rise-fall types, behind pump working, when fluid flow reaches rated pressure, opens flap by hydrodynamic pressure, but flap can produce certain resistance by convection cell after opening, and water displacement is affected, but also consumed energy.Though therefore existing check valve 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 technical problems to be solved in the utility model provides a kind of convection cell can not produce resistance, and water displacement is not had influence, can eliminate the line loss of discharge pipe line, improves the energy-conservation check valve device of pump efficiency.
Technical solution of the present utility model is as follows: 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 on valve body, in oil hydraulic cylinder, be provided with piston, below piston, be connected with the trip that is inserted in the valve body and flap can be caught on, on piston, be positioned at oil hydraulic cylinder and be provided 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 valve device, the insert division of corresponding trip is provided with copper sheathing on valve body.
Above-mentioned energy-conservation check valve device, described trip are the branch body structures that is formed by connecting by piston rod and hook, so that install.
The utility model has the advantages that: owing on 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 by the hydrodynamic pressure that enters oil hydraulic cylinder rises and the flap of opening can be caught on, make the fluid that enters valve body need not to overcome the resistance of flap and circulate, therefore convection cell can not produce any resistance, water displacement there is not influence, can eliminate 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, inlet pipeline 2, connecting tube 3, bearing pin 4, valve gap 5, oil hydraulic cylinder 6, spring 7, piston 8, trip 9, piston rod 901, hook 902, flap 10, copper sheathing 11.
Embodiment
As shown in the figure, this energy-conservation check valve device has a valve body 1, be respectively equipped with water intake 101 and water outlet 102 at valve body 1 two ends, upper end-hole at valve body 1 is fixed with valve gap 5, being hinged with by bearing pin 4 in valve body 1 can be with the flap 10 of valve inleting water mouth 101 shutoff, on valve body 1, by bolt oil hydraulic cylinder 6 is arranged near water outlet 102 1 sides, in oil hydraulic cylinder 6, be provided with piston 8, the center is connected with the trip 9 that is inserted in the valve body 1 and flap 10 can be caught on below piston 8, trip 9 is the branch body structures that are formed by connecting by piston rod 901 and hook 902, the insert division of corresponding piston rod 901 is provided with copper sheathing 11 on valve body 1, is positioned at oil hydraulic cylinder 6 and is provided with spring 7 on piston 8.Be connected with connecting tube 3 in oil hydraulic cylinder 6 lower ends, connecting tube 3 the other end be communicated with the inlet pipeline 2 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 2.During pump working, when the pressure in the inlet pipeline 2 reaches rating value, flap 10 is washed open, liquid is discharged by valve body 1, liquid in the inlet pipeline 2 is by enter in the oil hydraulic cylinder 6 connecting tube 3 simultaneously, promote piston 8 and trip 9 rises, catch on the flap of opening 10 and make it reach the maximum rising space after trip 9 rises, the fluid that enters valve body this moment need not to overcome the resistance of flap and circulates.When termination of pumping or have a power failure suddenly, the pressure moment in the inlet pipeline 2 is zero, and the pressure in the oil hydraulic cylinder 6 is by connecting tube 3 abrupt release, and under spring 7 effects, piston 8 and trip 9 fall after rise, flap 10 by gravity automatically upset with 101 sealings of valve inleting water mouth.
