Abstract
The invention discloses an air lock type electric exhaust valve which comprises an exhaust valve control motor, a locking air cylinder, an arresting disc, an exhaust valve main shaft, an exhaust valve body and an exhaust valve plate. The exhaust valve control motor is arranged at the upper end of the exhaust valve main shaft, the arresting disc and the exhaust valve plate are sequentially connected to the exhaust valve main shaft in series from top to bottom, the arresting disc and the exhaust valve plate are fixedly connected with the exhaust valve main shaft, the locking air cylinder is arranged above the edge of the arresting disc, and the exhaust valve control motor, the locking air cylinder, the arresting disc, the exhaust valve main shaft and the exhaust valve plate are all mounted in the exhaust valve body. According to the air lock type electric exhaust valve, the electric exhaust valve can be in a power-losing state through the locking control of the locking air cylinder, and the service life of the exhaust valve control motor is prolonged.
Description
Technical field
Gas exhausting valve while the present invention relates to a kind of engine test, relates in particular to a kind of gas locking electric-powered air release valve.
Background technique
When carrying out engine test, generally need to control the back pressure of exhaust, performance with test internal-combustion engine in some specific back pressure situations, it is comparatively simple control mode that manual tune is controlled, what employing was more now is electronic control, generally with actuating motor or stepper motor, but when exhaust back pressure is transferred to after certain setting value, generally need to keep considerable time, at this moment in order to stablize back pressure, motor generally will be switched on for a long time and be made its locking electric-powered air release valve, and this has just caused motor because of easily damage of long-term energising.
Summary of the invention
The object of the invention is to overcome the defect of prior art, a kind of gas locking electric-powered air release valve is provided.
For achieving the above object, the present invention proposes following technological scheme:
Comprise exhaust valve control motor, lock-up cylinder, arresting disc, outlet valve main shaft, exhaust valve and exhaust valve plate, described exhaust valve control motor is located at outlet valve main shaft upper end, on described outlet valve main shaft, be in series with successively from top to bottom described arresting disc and described exhaust valve plate, and described arresting disc is fixedly connected with described outlet valve main shaft with described exhaust valve plate, described lock-up cylinder is located at described arresting disc side margin top, and described exhaust valve control motor, lock-up cylinder, arresting disc, outlet valve main shaft, exhaust valve plate are installed in described exhaust valve.
Described exhaust valve plate has 4 semicircle leaves.
Described gas lock stops cylinder can be moved up and down and fix.
Between described lock-up cylinder and described arresting disc, pass through friction stop.
Described exhaust valve control motor can dead electricity after the stop of described outlet valve main shaft.
Therefore disclosed gas locking electric-powered air release valve, can be controlled and be allowed electric-powered air release valve in power failure state by the locking of lock-up cylinder, and extended the working life of exhaust valve control motor.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of gas locking electric-powered air release valve of the present invention.
Embodiment
Below in conjunction with accompanying drawing of the present invention, the technological scheme of the embodiment of the present invention is carried out to clear, complete description.
As shown in Figure 1, disclosed gas locking electric-powered air release valve, comprise exhaust valve control motor 1, lock-up cylinder 2, arresting disc 3, outlet valve main shaft 4, exhaust valve 5 and exhaust valve plate 6, described exhaust valve control motor 1 is located at outlet valve main shaft 4 upper ends, on described outlet valve main shaft 4, be in series with successively from top to bottom described arresting disc 3 and described exhaust valve plate 6, and described arresting disc 3 is fixedly connected with described outlet valve main shaft 4 with described exhaust valve plate 6, described lock-up cylinder 2 is located at described arresting disc 3 tops, edge, described exhaust valve control motor 1, lock-up cylinder 2, arresting disc 3, outlet valve main shaft 4, exhaust valve plate 6 is installed in described exhaust valve 5.
Described exhaust valve plate 6 has 4 leaves, and be semi-circular shape, described gas lock stops cylinder 2 can be moved up and down and fix, and between described lock-up cylinder and described arresting disc, by friction stop, described exhaust valve control motor can dead electricity after the stop of described outlet valve main shaft.
Particularly: when work; lock-up cylinder 2 is thrown off with arresting disc 3; first by exhaust valve control motor 1, by outlet valve main shaft 4, drive exhaust valve plate 6, exhaust duct during combustion motor test carries out aperture adjustment, to reach, adjusts the object of controlling exhaust back pressure; after reaching requirement; in the time of need to carrying out back pressure maintenance, lock-up cylinder 2 work are fixed arresting disc 3, thereby have guaranteed the stable of exhaust valve plate 6; now exhaust valve control motor 1 can dead electricity, reaches the object of protection motor.
Technology contents of the present invention and technical characteristics have disclosed as above; yet those of ordinary skill in the art still may be based on teaching of the present invention and announcements and are done all replacement and modifications that does not deviate from spirit of the present invention; therefore; protection domain of the present invention should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present invention and modifications, and contained by present patent application claim.
