Abstract
The invention discloses a high-pressure combustible gas valve opening and closing motor comprising a motor shell of which one end is sealed, a motor shaft, a rotor and a stator. An end cap is fixed at the open end of the motor shell. A sealed isolation sleeve capable of preventing gas from entering the internal cavity of the motor shell in which the rotor is positioned is arranged between the rotor and the stator. The sealed isolation sleeve comprises a sleeve body of which the internal end is sealed and a flange which is connected at the open end of the sleeve body. The internal end of the sleeve body stretches into the motor shell to be embedded in the internal wall of the sealed end of the motor shell. The motor internal cavities in which the rotor and the stator are respectively positioned are mutually isolated by the sealed isolation sleeve so that high-pressure combustible gas cannot enter the motor internal cavity in which the stator is poisoned after permeating into the motor internal cavity through the bearing gap of the motor. Therefore, environmental pollution and the risk of explosive combustion caused by exhausting of combustible gas to the external atmosphere can be prevented, and the requirement for normal working of the motor in a high-pressure system can be met.
Description
Technical field
The present invention relates to a kind of high pressure fuel gas valve opening and closing motor.
Background technology
On the container storing high pressure fuel gas, the unlatching of valve changes Electric Machine Control into by manual type in the past and opens, with regard to the sealing of existing motor, it only can prevent dust from entering motor cavity, do not possess the sealing property of bearing pressure differential, pressed gas cannot be stoped to enter motor cavity, and in actual use, after valve opening, because rotor two ends by bearings respectively, when machine operation is in rotation status, the fuel gas of high pressure penetrates into motor cavity easily via the gap of motor bearings, and after be discharged in ambient atmosphere through the fairlead of stator winding, both environmental pollution was caused, there is again the danger of flammable gas explosion burning, therefore existing electric machine structure is difficult to meet the requirement of normal work in high pressure systems.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of and can prevent high pressure fuel gas from entering motor cavity, meets the high pressure fuel gas valve opening and closing motor of normal job requirement in high pressure systems.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high pressure fuel gas valve opening and closing motor, comprise the casing that one end is closed, motor shaft, the stator being fixed on the rotor on motor shaft and being fixed in chassis cavity, casing openend is fixed with end cap, motor shaft puts in chassis cavity through end cap, the seal isolation cover that gas can be stoped to enter rotor place chassis cavity is provided with between described rotor and stator, described seal isolation cover comprises the inner sleeve body closed and the flange being connected to sleeve body openend, sleeve body the inner puts in casing and is embedded in casing blind end inwall, flange and end cap outer face are fixed, rotor is positioned at sleeve body, stator is positioned at outside sleeve body.
Further, the openend inwall of described sleeve body is provided with front-end bearing pedestal, and sleeve body blind end inwall is provided with rear bearing block, is respectively equipped with the bearing of support motor axle front and back end in axle bearing.
The inwall of described casing blind end has inner cavity, and the inner cooperation of sleeve body is embedded in inner cavity.
The invention has the beneficial effects as follows: the present invention by arranging seal isolation cover between the rotor and stator of motor, the motor cavity at rotor and stator place is separately spaced from each other, after the fuel gas of so extraneous high pressure penetrates into motor cavity by the gap of motor bearings, just be trapped in the motor cavity at rotor place, cannot enter in the motor cavity at stator place, thus prevent the danger that fuel gas is discharged to environmental pollution and the explosive combustion caused in ambient atmosphere, meet the requirement of motor normal work in high pressure systems.

Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of high pressure fuel gas valve opening and closing motor as shown in Figure 1, comprise one end and close the casing 1 of one end open, motor shaft 2, the stator 4 that is fixed on the rotor 3 on motor shaft 2 and is fixed in casing 1 inner chamber, the openend of casing 1 is fixed with end cap 5, motor shaft 2 puts in casing 1 inner chamber through end cap 5, and the inwall of casing 1 blind end has inner cavity.
The seal isolation cover that gas can be stoped to enter rotor 3 place casing 1 inner chamber is provided with between described rotor 3 and stator 4, described seal isolation cover adopts the stainless steel of high strength to make, it comprises the inner sleeve body 6-1 closed and the flange 6-2 being connected to sleeve body 6-1 openend, sleeve body 6-1 the inner puts in cooperation in casing 1 and embeds in the inner cavity of casing 1 blind end inwall, flange 6-28 and end cap 5 outer face are fixed, rotor 3 is positioned at sleeve body 6-1, and stator 4 is positioned at outside sleeve body 6-1.
The openend inwall of described sleeve body 6-1 is provided with front-end bearing pedestal 7, and sleeve body 6-1 blind end inwall is provided with rear bearing block 8, is respectively equipped with the bearing 9 of support motor axle 2 front and back end in axle bearing 7,8.
The present invention by arranging seal isolation cover between the rotor 3 and stator 4 of motor, the motor cavity at respective to rotor 3 and stator 4 place is spaced from each other, like this after the fuel gas of extraneous high pressure penetrates into motor cavity by the gap of the bearing 9 of motor, just be trapped in the motor cavity at rotor 3 place, cannot enter in the motor cavity at stator 4 place, thus prevent the danger that fuel gas is discharged to environmental pollution and the explosive combustion caused in ambient atmosphere, meet the requirement of motor normal work in high pressure systems.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
