Summary of the invention
A kind of aircraft waterwheel hydraulic pressure and manual blowdown device have been the object of this invention is to provide, from following principle, solve this defect: can meet can be when hydraulic pressure installation be made a fault at hydraulic pressure and manual blowdown device, can mistake not open valve, now recycle the opening and closing that manual operating device is realized valve.
In order to achieve the above object, the invention provides following technological scheme:
Aircraft waterwheel hydraulic pressure and a 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.In invention, owing to utilizing hydraulic pressure installation easily to cause when error valve mistake to open, sewage can be because of the trickling everywhere of opening of valve; Therefore, while avoiding hydraulic pressure installation easily to cause error, valve mistake is opened, and avoids hydraulic pressure installation easily to cause error, and the sewage in case can be realized 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: while avoiding hydraulic pressure installation easily to cause error, valve mistake is opened, and avoids hydraulic pressure installation easily to cause error, the sewage in case can be realized emergency operation function because of the trickling everywhere of opening of valve, improves the reliability simplicity of work.Can bring good economic benefit, cost-saving, 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 as shown in, aircraft waterwheel hydraulic pressure and a 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 andspring 8, hydraulic jack 9,fluid discharge pipeline 10, hydraulic jack mounting base 11.In invention, owing to utilizing spring and the position-limitting pin of handle position-limitting pin andspring 8, can control to the characteristic of handle release and locking, in conjunction with 6 designs of spherical termination; Therefore, while avoiding hydraulic pressure installation easily to cause error, valve mistake is opened, and avoids hydraulic pressure installation easily to cause error, and sewage can be realized 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 aircraft waterwheel transports the Water Tank of filling sewage, now worm screw handle 4, in the bottom of handle position-limitting pin andspring 8, is fixed with position-limitting pin and spring, because worm screw 1 can be realized the function with the large-scale ball valve 2 of manual operation with the drive mechanism of tooth sector 3.
As shown in Figure 3,spherical termination 6 is used in worm screw handle 4 one end, realize to rotate and on lift worm screw handle 4 and carry out release.
As shown in Figure 4, hydraulic jack 9 is used hydraulicjack mounting base 11 to be directly installed on 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 aircraft waterwheel transports the Water Tank of filling sewage, now worm screw handle 4 is on the top of handle position-limitting pin andspring 8, with position-limitting pin and spring, fix, after pressing down worm screw handle 4 and putting in place, worm screw 1 is realized engagement with tooth sector 3, can be by hydraulic jack 9 positive locks, because worm screw 1 can be realized the function with the large-scale ball valve 2 of manual operation with the drive mechanism of tooth sector 3.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 worm screw 1 can be realized the function with the large-scale ball valve 2 of manual operation with the drive mechanism of tooth sector 3.As shown in Figure 3,spherical termination 6 is used in worm screw handle 4 one end, 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, because of the opening of ball valve 2 mistakes, flow out from fluid discharge pipeline 10.When can prevent that hydraulic system is malfunctioning thus, sewage can, because of the opening of ball valve 2 mistakes, flow out from fluid discharge pipeline 10.If lift to behind position from worm screw handle 4, worm screw handle 4 is on the top of handle position-limitting pin andspring 8, and worm screw 1 is removed engagement with tooth sector 3, and now hydraulic jack 9 can move, and realizes electricity consumption console keyboard and opens and throttle down.
According to above-mentioned working principle: owing to utilizing 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, while avoiding hydraulic pressure installation easily to cause error, valve mistake is opened, avoid hydraulic pressure installation easily to cause error, 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, emergency operation function, makes simply, improves the reliability simplicity of work.
