The present invention is applicable to the technical field of quick-opening valves, and provides a quick-opening valve exhaust silencing device and a method of use thereof, including a straight pipe part, a first silencing part, a telescopic pipe part and a second silencing part, the straight pipe part One end is connected with a connecting flange, the connecting flange is connected with the flange of the valve, the other end of the straight pipe part is connected to the front end of the first muffler part, the rear end of the first muffler part is connected to the front end of the telescopic pipe part, and the rear end of the telescopic pipe part The end is connected to the second muffler part, the second muffler part has muffler one, muffler two and muffler three, to realize the multi-stage exhaust noise reduction of the second muffler, and also includes telescopic pipe section, which can effectively absorb the exhaust of the device The huge impact force received during the process; the exhaust muffler device of the present invention can produce a relatively good muffler effect when discharging high-pressure gas, greatly reducing noise, and at the same time the muffler device can better absorb the impact force generated by air vibration and protect other components , and each component can be replaced, which improves the economy of the device.

The invention provides a detection device and method for observation and measurement of the inner wall of a deep hole. The method comprises the steps that a clamping device (1) on an upper workbench (2) clamps a deep hole test piece; and a horizontal axis microdrum (3), a vertical axis microdrum (5), an elevating handle (8) and an angle adjusting turn button (10) are adjusted so that light of a spot light source (12) is input to the visual field of a stereomicroscope (13) from the bottom of the deep hole test piece and upwardly through the deep hole test piece. Thus, a clear visual field of high field depth can be obtained, and the inner wall of the deep hole test piece can be observed and measured in multiple angles.

The invention discloses a disposable combinational membrane module which is composed of combinational joints, hollow fiber membrane yarns and a membrane shell, wherein the combinational joints are arranged at the two ends of the disposable combinational membrane module, and the hollow fiber membrane yarns are arranged in the middle of the disposable combinational membrane module; the combinational joints comprise an upper combinational joint and a lower combinational joint, the lower combinational joint is provided with an aeration device, a casting head part is cast in a way of partitioned casting, and aeration discs are uniformly distributed in each casting interval, so that membrane bundle yarns in a membrane pipe fitting are uniformly distributed, and poor water-passing and aeration cleaning effects are not caused when the membrane bundle yarns are distributed excessively densely. In the disposable combined membrane module, disposable parts comprise a membrane connector, a membrane casting head and a membrane pipe, namely, when a membrane runs to a certain time or the membrane is contaminated and blocked seriously and can not reach requirements after being cleaned, a mode of directly replacing the membrane connector, the membrane casting head and the membrane pipe is adopted in the invention and the mode is more economic and environmental-friendly as compared with the traditional mode of replacing a whole membrane module; and after a membrane stack is formed, only an operation of connecting ports of a whole stack of membrane devices with a main water inlet pipe and a main water outlet pipe is required to be performed, so that the filling density is greatly improved, space can be saved and a lot of pipe fittings are also saved.
