Abstract:
A multi-level waterway control device has: a fixed unit, a flow regulating plate, a function switching plate and a drive unit. Flow regulation is achieved through the relative rotation between the flow regulating plate and the fixed unit. The outlet functions switch is achieved through the relative rotation between the function switching plate and the fixed unit. The drive unit can slide and rotate relative to the fixed unit, at least happen between the first and second position. When the drive unit is at the first position, it can form a synchronous rotation connection with the flow regulating plate, and the drive unit can drive the rotation of the flow regulating plate to achieve flow regulation. In the second position, the drive unit can form a synchronous rotation connection with the function switching plate, can drive the rotation of the function switching plate to achieve outlet functions switch.
Abstract:
A folding clamshell shower has a body containing a water passage, a water diversion unit and an outlet unit. The outlet unit is rotationally and pivotally connected with the body to form the folding clamshell structure. The outlet unit is provided with at least two outlet functions; the water diversion unit is mounted at the rotary pivot joint site of the outlet unit and the body, and comprises a water diversion body; the rotation of the water diversion body relative to the body can be driven by the rotation between the outlet unit and the body, the relative rotation between the water diversion body and the body controls outlet functions of the shower to pause or switch.
Abstract:

The fixed unit is provided with a inlet and at least two independent mounting cavities, an outlet is formed at the lower port of the mounting cavity; two control valves are mounted in the mounting cavities respectively; and the control valve comprises a spool assembly, a first magnet, a sealing gasket, a first spring and a second spring. The spool assembly is fixedly arranged in the mounting cavity with a pressure relief way; the first magnet which is connected in the mounting cavity in an up and down sliding manner and is above the spool assembly; the sealing gasket is connected in the mounting cavity in a vertical sliding manner and is below the spool assembly; the second magnet is connected out of the fixed unit in a horizontal sliding manner.
Abstract:
A process of producing chlorine gas by catalytic oxidation of hydrogen chloride including: incorporating an oxidizing agent such as ozone, hydrogen peroxide solution etc. into a gas stream of hydrogen chloride containing impurities, conducting oxidation pretreatment of the gas stream under the action of ultrasonic wave, such that the impurities contained in the gas stream are oxidized; wherein the oxidizing agent does not generate additional or new impurities in the reaction system, where the gas stream obtained after the oxidation pretreatment is allowed to pass through a separating device wherein the oxidized impurities in the form of liquid and/or the oxidized impurities in the form of solid are removed from the gas stream so as to obtain a purified gas stream of hydrogen chloride, and thereafter the purified gas stream of hydrogen chloride is well mixed with a gas stream containing molecular oxygen, the resultant gas mixture is preheated to a reaction temperature, and then catalytically oxidized to produce chlorine gas, thus by means of oxidation pretreatment and separation, the process can remove efficiently the sulfur-containing impurities, the halogen-containing impurities, hydrocarbon impurities and the like from the gas stream of hydrogen chloride, and does not generate additional impurities.
Abstract:

Abstract:
An air-intake and focused type sprayer apparatus includes: a convergence chamber having a large end and a small end of varying sizes along the axial direction, an inner wall provided with a gradual transition between the large end and the small end, at least two water inlet paths in communication with the large end, where all of the water inlet paths converge within the convergence chamber towards an water discharging direction of the convergence chamber, at least one air intake passage in communication with the convergence chamber from the external open space, and a rectifier opening in communication with the small end and provided with a throat for allowing water flow to form a liquid seal. The cross-section area of the throat is one to three times larger than the maximum total cross-section area of the water inlet path; the rectifier opening gradually increases in the cross-section size outwards.

Abstract:
An angle positioning device of a rotation shaft includes a first pivot portion and a second pivot portion. The first pivot portion includes a first face having a positioning portion, a first path and a second path divided by the positioning portion. The first pivot portion includes a second face having a returning portion, a third path and a fourth path divided by the returning portion. The second pivot portion can move along the first path, the second path, the third path, and the fourth path. When the second pivot portion moves from the first path to the second path, the pivot angle is increased. When the second pivot portion moves from the third path to the fourth path, the pivot angle is decreased. When the pivot portion moves from the first path to the positioning portion, the pivot angle cannot be decreased. The second pivot portion can move from the third path through the returning portion and back to the first path.
