Description
Technical field
This utility model belongs to hydropneumatics field, it is specifically related to a kind of maximum amount of water for releasing and the shortest time released according to test platform during test, carry out while water puts test or false weapon test at test platform, it is released to release in water tank by the air-water mixture that transmitting tube reclaims, and realize gas and water separation by acoustic filter, reduce the device of noise, be a discharger ingredient repairing test platform on hinterland.
Background technology
Existing part discharger uses aerodynamic non-balance radiation pattern.In emission process, the compressed air in transmitting tube promotes weapon to go out pipe, in order to ensure disguise, prevents compressed air from exposing, needs by bleeder, the Partial shrinkage air in transmitting tube and part sea water are reclaimed at short notice and be released in water tank.Test platform on hinterland repaiied by discharger is to simulate real sea water working environment, when carrying out water and putting or launch false weapon test, it is also desirable to release at short notice the Partial shrinkage air in transmitting tube and water.
At present, in order to ensure that water is put test and launches being smoothed out of false weapon test, need to release the Partial shrinkage air in transmitting tube and water during each emission test, realization means has two kinds: a kind of cistern being to arrange an enough capacity in the side of test platform, when testing every time, the Partial shrinkage air that needs are released by bleeder by pipeline and water are directly released in cistern, owing to compressed air and water simultaneously enter cistern at short notice, according to the difference launching pressure set by different depth, the water being released in cistern will form tens meters of high water columns under compressed-air actuated effect, and produce huge noise, the safety of emission test and the physically and mentally healthy of operator are produced impact.Another kind is to use the compression muffler being made up of water tank of releasing, acoustic filter to reclaim the compressed air and water released, the Partial shrinkage air and water released is reclaimed with water tank of releasing, and the gas and water separation releasing in water tank is realized by acoustic filter, the compressed air of water tank of releasing is discharged after being reduced pressure by acoustic filter, remaining water is then discharged in cistern by the drainage pipeline of water tank of releasing, which ensure that water is put test and launches being smoothed out of false weapon test, improve reliability and the safety of test platform, it is to avoid the adverse effect directly released.
Summary of the invention
The purpose of this utility model is to provide a kind of and repaiies test platform water on hinterland for discharger and put test and launch the silencing means that false safety of weapons is released.
The silencing means of releasing that the utility model proposes, is mainly made up of acoustic filter, water tank etc. of releasing.The discharge outlet of the bleeder water inlet of water tank upper end of releasing utilizes bolt to be attached with the discharge outlet of bleeder by flange, and the make a slip of the tongue water inlet of bolt and the water-retention pipeline of side of water tank lower end draining of releasing utilizes bolt to be attached by flange；Two acoustic filter interfaces that two acoustic filters are arranged with water tank upper end of releasing utilize bolt to be attached by flange.
Silencing means main operational principle of releasing is: Partial shrinkage air that when water tank of releasing is mainly used in recovery test, bleeder is released and water, realizes gas and water by its acoustic filter installed above and separates.Wherein, acoustic filter be internally provided with decompressor, enter the compressed-air actuated pressure in acoustic filter for reducing water tank of releasing, compressed air is changed into low-pressure gas, then the low-pressure gas after changing discharges acoustic filter, by the effect of resistive noise reduction section, thus reaches the purpose that noise-decreasing puies forward.The interior water reclaimed of water tank of releasing, because without compressed-air actuated effect, being drained in cistern by mild for the drainage pipeline by water tank of releasing, thus reaches to guarantee the purpose of process of the test reliability, safety.
This utility model good stability, service life is long, it is ensured that the reliability of process of the test and safety, is greatly improved test efficiency, shortens the test period, reduces the injury that the noise produced of releasing brings to testing crew simultaneously.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
1.1 release waterbox design.
In order to take into account the maximum amount of water (700L) that test platform is released, the compressive resistance of cylinder and release the shortest time (3.3S), this programme selects a diameter of Φ 1120mm, the cylinder of the Q345R plate of a length of 2500mm, inner barrel is provided with impingement baffle assembly and baffle assembly, wherein, impingement baffle assembly is A-frame shape, it is welded in the both sides letting out caisson inner upper, the lower section in silencer air inlet pipe road, directly wash away the admission line of acoustic filter primarily to prevent the gases at high pressure entering in the air-water mixture of water tank of releasing from rising and cause pipe vibration unstability and corrosion；Baffle assembly is installed on the outlet of water tank internal drainage pipeline of releasing, and outlet is completely covered, and its effect, primarily to reinforcement is with separating, improves the intensity of whole water tank, prevents interlayer seepage.Simultaneously, the water inlet using a diameter of Φ 170mm directly over water tank of releasing is taken over, meet water tank of releasing and within the shortest time of releasing, all can reclaim the water yield that bleeder is released, the discharge outlet that underface weld diameter is Φ 120mm at water tank of releasing is taken over, it is connected with cistern by pipeline, in order to the water that water tank of releasing can drain in water tank after having released.Separate in addition to realize gas and water, need to be arranged above two vent connections at water tank of releasing, for connecting two acoustic filters.Release water tank specific design as shown in Figure 1.
The key technical indexes of water tank of releasing is as follows:
(1) working media: compressed air and water；
(2) total volume: 800L；
(3) operating temperature :+50 DEG C；
(4) compressive resistance: 3.0MPa.
1.2 muffler desing.
Compressed air pressure owing to reclaiming in water tank of releasing is higher, so needing to arrange three grades of decompressors at the air inlet of the lower inside gases at high pressure of acoustic filter, whole decompressor is made up of one, two, three relief pipe, gases at high pressure are by after three grades of relief pipes, gas pressure reduces, thus reduce the flow velocity of gas, make gas flow rate steady, reduce the impact to acoustic filter body；Additionally the top of acoustic filter also needs to arrange resistance noise reduction section, resistance noise reduction section is installed on above decompressor and between rain cap, primarily to dissipate by acoustic energy being converted into heat energy with the friction of high pressure draught, the noise along pipe transmmision is made to decay with distance.Meanwhile, in order to prevent pouring into of rainwater, need in the top side of acoustic filter to install umbrella shape rain cap additional.
Deafener the key technical indexes is as follows:
(1) treating capacity: 100t/h；
(2) operating temperature :+50 DEG C；
(3) operation pressure: 2.0MPa.
