A ball valve having a cam element, and a ball having a left arm and a right arm with a slot between each arm. A terminal portion of each arm is positioned adjacent the cam element. The cam element is shaped so that, when the ball is rotated from the open condition to the closed condition, the cam element forces the arms through three distances of separation. A first distance, when the ball has undergone no rotation from the fully open condition. A second distance, when the ball has undergone some rotation from the fully open condition towards the closed condition but has not reached the closed condition. A third distance in which the ball has undergone rotation to the closed condition. The third distance is greater than the first distance, and the second distance is greater than the third distance.

The invention discloses a steel box body buckle hat type temporary construction road, and relates to the technical field of road construction, in particular to a pavement technology of a temporary road in a construction site. The steel box body buckle hat type temporary construction road comprises a plurality of box body assemblies which are sequentially connected, the box body assembly in each group comprises a rectangular steel plate box body, I-shaped steel, a steel buckle hat, a fixator, a sleeve and a fixing pile, an opening is formed in the lower end of the rectangular steel plate box body, the sleeve is vertically arranged, and the fixing pile is vertically arranged; the I-shaped steel and the steel buckle hats are welded at the top parts of the inner sides of the steel plate box bodies; the upper surfaces of the steel buckle hats are flat surfaces, and the lower surfaces of the steel buckle hats are concave semi-spherical surfaces; the upper parts of the sleeves are semi-spherical bodies and are arranged in the semi-spherical surfaces of the steel buckle hats in a matching way; the lower parts of the sleeves are arranged at the upper parts of the fixing piles in a sleeving way; the sleeves are connected with the I-shaped steel through the fixators. Compared with a traditional temporary construction road, the steel box body buckle hat type temporary construction road disclosed by the invention has the advantages that the requirements on a site are lower, the steps are simple, the assembly is quick, and stronger response capacity on route change and pipeline change is obtained; meanwhile, turnover use can be realized, and green construction is ensured.

The invention discloses a perovskite precursor solution and its application in preparing solar cells. The perovskite precursor solution includes the following components in mass percentage: methyl iodide 2.56%~9.46%, methyl bromide 0.13%~2.35%, methyl iodide 3.54%~11.90%, lead iodide 28.63%~53.60% , lead bromide 2.44%~7.70%, chloroformamidine 0~10.20%, dimethyl sulfoxide 2.61%~11.68%, N,N-dimethylformamide 14.79%~35.02%, γ-butyrolactone 16.85% ~42.49%. The invention utilizes the perovskite precursor solution to prepare the light-absorbing layer of the perovskite solar cell, which can be spin-coated in an open atmospheric environment, which is convenient for preparation, and can be transferred to a vacuum environment after spin-coating to form a non-porous and dense large The perovskite light-absorbing layer with grain size has high photoelectric conversion efficiency.

The invention discloses a handlebar structure convenient to brake. The handlebar structure is located on the front side of a bicycle body frame, and comprises a handlebar rod, a limiting rod fixed tothe bicycle body frame and a braking line. The braking line comprises an inner core and a shell. A braking hole containing the inner core of the braking line to pass through and blocking the shell ofthe braking line is formed in one side of the limiting rod. A connecting rod is arranged between the handlebar rod and the limiting rod. Two ends of the connecting rod are correspondingly rotatably connected with the handlebar rod and the limiting rod. The limiting rod is internally provided with a connecting groove capable of containing rotation of the connecting rod. The inner core of the braking line extends into the handlebar rod through the braking hole. The handlebar rod is internally provided with a control assembly capable of fixing the inner core of the braking line. The handlebar structure has the beneficial effects that hand griping brake is converted into arm pushing brake, and therefore persons with small hands or little hand strength can use appropriately, and the braking effect is reliable; normal riding of the bicycle body can be conducted after the handlebar rod is completely reset manually, and therefore security is high; and the higher the bicycle speed is, the better matching of the inertia braking is, and emergency response capacity is high.

The invention discloses a quick collection system for distributed internet data. The system comprises five layers including a seed website setting node, a hyperlink collection layer, a real-time queue, a webpage downloading and parsing layer and a webpage data storage layer, wherein the seed website setting node is used for setting each parameter and each extracting rule for storing a data source; the hyperlink collection layer is used for requesting the hyperlink list webpage of the data source and extracting the hyperlink of a target webpage; the real-time queue is used for accessing a URL (Uniform Resource Locator) hyperlink extracted by the hyperlink collection layer, the extraction rule corresponding to the URL hyperlink and the accessed URL hyperlink; the webpage downloading and parsing layer is used for requesting and parsing the URL hyperlink which is not accessed in the real-time queue and carrying out formatting extraction on specific data; and the webpage data storage layer is used for storing target data obtained by the formatting extraction carried out by the webpage downloading and parsing layer.
