Abstract
The utility model provides a hydraulic and manual blowdown device of an airplane water wagon. The device is characterized by comprising a worm, a ball valve, a sector gear, a worm handle, a worm handle seat, a spherical end head, a handle guide slot, a limiting seat, a handle limiting dowel, a spring, a hydraulic oil cylinder, a liquid discharge pipeline and a fitting base of the hydraulic oil cylinder. According to the device, sewage flows everywhere if the valve is mistakenly and easily opened through utilizing a hydraulic device, so that the valve is prevented from mistakenly and easily opened when the hydraulic device is utilized, faults are prevented from being easily caused by the hydraulic device to cause the sewage in a tank to flow everywhere through the opened valve, an emergency operation function is realized, and the working reliability and convenience are improved.
Description
Technical field
The present invention relates to a kind of drainage device, particularly relate to aircraft waterwheel drainage device.
Background technique
At present, the whole world existing aircraft waterwheel drainage device is a hydraulic pressure installation, because of hydraulic pressure installation work has no idea to reach perfect, cause error easily, cause the valve mistake to open during error, when filling sewage and transport, the sewage in the case can cause traffic congestion and befouling environment in the serious airdrome because of the trickling everywhere of opening of valve.Therefore, handle and to clear up by a large amount of manpower physical resources of cost.
Summary of the invention
A kind of aircraft waterwheel hydraulic pressure and manual blowdown device have been the purpose of this invention is to provide, solve this defective from following principle: can satisfy can be when hydraulic pressure installation be made a fault at hydraulic pressure and manual blowdown device, can mistake not open valve, utilize manual operating device to realize the opening and closing of valve this moment again.
In order to achieve the above object, the invention provides following technological scheme:
A kind of aircraft waterwheel hydraulic pressure and manual blowdown device is characterized in that it comprises: worm screw, ball valve, tooth sector, worm screw handle, worm screw handle set, spherical termination, handle guide groove and position limit socket, handle position-limitting pin and spring, hydraulic jack, fluid discharge pipeline, hydraulic jack mounting base.Worm screw is connected with tooth sector; Ball valve is connected with tooth sector; Worm screw is connected with the worm screw handle; Tooth sector is connected with hydraulic jack; Handle guide groove and position limit socket are located at worm screw handle one end; The fluid discharge pipeline is located at hydraulic jack one side; Handle position-limitting pin and spring are located in handle guide groove and the position limit socket; The hydraulic jack mounting base is located at worm screw handle one side.In invention, owing to utilize hydraulic pressure installation to cause when error valve mistake to open easily, sewage can be because of the trickling everywhere of opening of valve; Therefore, the valve mistake is opened when avoiding hydraulic pressure installation to cause error easily, avoids hydraulic pressure installation to cause error easily, and the sewage in the case can be realized the emergency operation function because of the trickling everywhere of opening of valve, improves the reliability simplicity of work.
The invention has the beneficial effects as follows: the valve mistake is opened when avoiding hydraulic pressure installation to cause error easily, avoids hydraulic pressure installation to cause error easily, and the sewage in the case can be realized the emergency operation function because of the trickling everywhere of opening of valve, improves the reliability simplicity of work.Can bring good economic benefits, save cost, easy and simple to handle.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further elaborated.
As Fig. 1 and shown in, a kind of aircraft waterwheel hydraulic pressure and manual blowdown device is characterized in that it comprises: worm screw 1, ball valve 2, tooth sector 3, worm screw handle 4, worm screw handle set 5, spherical termination 6, handle guide groove and position limit socket 7, handle position-limitting pin and spring 8, hydraulic jack 9, fluid discharge pipeline 10, hydraulic jack mounting base 11.In invention, owing to utilize the spring and the position-limitting pin of handle position-limitting pin and spring 8, can control to the characteristic of handle release and locking, in conjunction with 6 designs of spherical termination; Therefore, the valve mistake is opened when avoiding hydraulic pressure installation to cause error easily, avoids hydraulic pressure installation to cause error easily, and sewage can be realized the emergency operation function because of the trickling everywhere of opening of valve, improves the reliability simplicity of work.
As shown in Figure 1 and Figure 2, when the aircraft waterwheel transports the sewage jar of filling sewage, worm screw handle 4 is fixed with position-limitting pin and spring in the bottom of handle position-limitting pin and spring 8 at this moment, because the drive mechanism of worm screw 1 and tooth sector 3 can be realized the function with the large-scale ball valve 2 of manual operation.
As shown in Figure 3, worm screw handle 4 one ends use spherical termination 6, realize to rotate and on lift worm screw handle 4 and carry out release.
As shown in Figure 4, hydraulic jack 9 uses hydraulic jack mounting base 11 directly to be installed on the ball valve 2, can save materials and installing space.
The working principle of above-mentioned aircraft waterwheel hydraulic pressure and manual blowdown device is: when the aircraft waterwheel transports the sewage jar of filling sewage, worm screw handle 4 is on the top of handle position-limitting pin and spring 8 at this moment, fix with position-limitting pin and spring, press down after worm screw handle 4 puts in place, worm screw 1 is realized engagement with tooth sector 3, can be with hydraulic jack 9 positive locks, because the drive mechanism of worm screw 1 and tooth sector 3 can be realized the function with the large-scale ball valve 2 of manual operation.Normal manually-operable, turn worm screw handle 4 can be closed ball valve 2 counterclockwise, and turn worm screw handle 4 can be opened ball valve 2 clockwise, and the drive mechanism of worm screw 1 and tooth sector 3 can be realized the function with the large-scale ball valve 2 of manual operation.As shown in Figure 3, worm screw handle 4 one ends use spherical termination 6, realize to rotate and on lift worm screw handle 4 and carry out release.When can prevent that hydraulic system is malfunctioning thus, sewage can flow out from fluid discharge pipeline 10 because of the opening of ball valve 2 mistakes.When can prevent that hydraulic system is malfunctioning thus, sewage can flow out from fluid discharge pipeline 10 because of the opening of ball valve 2 mistakes.After lifting to the position as if worm screw handle 4, worm screw handle 4 is on the top of handle position-limitting pin and spring 8, and worm screw 1 is removed engagement with tooth sector 3, and this moment, hydraulic jack 9 can move, and realization electricity consumption console keyboard is opened and throttle down.
According to above-mentioned working principle: owing to utilize the spring and the position-limitting pin of handle position-limitting pin and spring, can control to the characteristic of handle release and locking, in conjunction with the design of spherical termination; Therefore, the valve mistake is opened when avoiding hydraulic pressure installation to cause error easily, avoid hydraulic pressure installation to cause error easily, sewage can be because of the trickling everywhere of opening of valve, realize the function of locking oil hydraulic cylinder and light manually-operable valve, the emergency operation function is made simply, improves the reliability simplicity of work.
