Abstract
The utility model discloses a mechanical electrically operated valve which comprises a valve body and an actuator connected with the valve body. The valve body is provided with a water inlet and a water outlet. The actuator comprises a shell body and an electric motor cover. A piston rod is arranged in the shell body and connected with the shell body in a sliding mode. The piston rod and the water outlet are coaxially arranged. The piston rod is located on a sealant head of one end of the water outlet, and the other end of the piston rod is connected with an eccentric shaft which is connected with a micro electric motor through a speed reducer. The mechanical electrically operated valve improves control ability of the valve and can conveniently control flow. Small torque of the electric motor can be shifted to large torque through the speed reducer. Power dissipation is low, operating voltage range is wide, and the mechanical electrically operated valve can reliably operate within 1.4-7.5 volt voltage range. Controlled hydraulic pressure is 0-0.8 MP. Self-lock of the piston rod can be generated due to the big transmission ratio of the speed reducer and can stabilize the flow. The mechanical electrically operated valve separates the piston rod from liquid through a seal sleeve, and is low in requirement of degree of purity of media, strong in universality, and wide in application scope.
Description
Technical field
The utility model relates to a kind of mechanical type electric valve, belongs to technical field of valve control.
Background technique
Electrical heads on the at present domestic and international institute use solenoid valve is the self-closing electromagnetic head, is comprised of coil, o type circle, piston, sealing gasket, and working principle is that the energising of self-closing electromagnetic head coil produces magnetic field, drives piston rod by magnetic force and moves.When piston rod ejected, the coil magnetic force will overcome pressure and the resistance of spontaneous magnet suction and water.When piston rod returned, the coil magnetic force will overcome the elastic force of self-sustaining spring and the resistance of water.The magnetic force that coil produces will just can be finished very greatly above two actions, so the power supply of electromagnetic coil will have 5V-6V just can make electromagnetic coil produce enough large magnetic force.Because existing piston rod directly contacts with water, and is higher to water quality requirement, when more such as the impurity in the water, often can be stuck piston rod, need to often clean.In addition, solenoid valve can only have out and close two kinds of working staties, can not remain on any opening degree state by control valve.Sometimes the self-closing electromagnetic head is subject to extraneous vibrations original state can't be kept, and produces misoperation, and working stability is undesirable.
Summary of the invention
The purpose of this utility model is, a kind of mechanical type electric valve is provided.Replace existing electromagnetic coil with motor, can make the free position of valve working between Push And Release; Power consumption is little, and operating voltage range is wide, and is not high to water quality requirement, improves the reliability of valve working.
The technical solution of the utility model:
A kind of mechanical type electric valve comprises valve body and the driver that is connected with valve body, and valve body is provided with water intake and water outlet; Driver comprises housing, is provided with piston rod in the housing, and piston rod and housing are slidingly connected, piston rod and the coaxial setting of water outlet, one end of piston rod is positioned at the sealer head of water outlet one end, and the other end of piston rod is connected with eccentric shaft, and eccentric shaft is connected with micromachine through retarder.
In the aforementioned mechanical type electric valve, the one side that the sealer head is positioned at the water outlet side is plane or the conical surface.
In the aforementioned mechanical type electric valve, described piston rod is provided with stuffing box gland outward, and an end and the sealer head of stuffing box gland connect as one, and the other end of stuffing box gland is connected with the housing of driver.
In the aforementioned mechanical type electric valve, described stuffing box gland is corrugated hose.
Compared with prior art, the utility model has substituted electromagnetic coil in the existing solenoid valve with micromachine, has improved the control ability of solenoid valve.Existing solenoid valve generally is to be in closed condition when outage, is in full-gear during energising, only has two kinds of working staties of opening and closing, does not have intermediateness, can not control flow.Piston rod of the present utility model can make piston rod rest on the arbitrary position of working stroke under the drive of micromachine, can control easily flow by the aperture that changes sealer head and water outlet.Retarder in the utility model can turn to high pulling torque with the little torque axis of motor, and controlled hydraulic pressure is higher, can reach 0～0.8MP.Micromachine is low in energy consumption, can work under low voltage, and operating voltage range is wider, can both reliably working in 1.4～7.5V voltage range.The big speed ratio that slows down simultaneously can produce self-locking to piston rod, under large Water Pressure, can not produce displacement by the pushing piston bar, can regime flow.With piston rod and liquid isolation, piston rod can be not stuck by the impurity in the medium when to-and-fro motion by stuffing box gland for the utility model, thus lower to the degree of purity requirement of medium, highly versatile, accommodation is large.The utility model is simple in structure, and processing cost and cost of material are all lower.Can improve the market competitiveness.
