Be composed of valve body , bonnet , valve seat , starting and stopping a piece , driving organization , sealing off and tightening firmware and so on generally. The valve control function is to depend on that drive organization or the fluid urges starting and stopping the size piece, going up and down , slipping , swaying immediately or turning round to change runner area to come true. Be used for industry and agriculture childbirth and daily life appliance middle broadly. Valve classification method is manys, but is that what be played role carries out classification according to the person in the pipeline mainly. The valve being applied or used universally in industry and civil project may divide into 11 kinds , be a valve , stop valve , stop cock , ball check , butterfly gate , baffle valve , non-return valve , throttle valve , relief valve , compression release valve and sparse water valve. Can the main body of a book be arranged for to valve structure being applied or used universally several kinds right away, operation and the upkeep are carried out studying, place of being tied in wedlock various valve diversity , the analysis being in progress to them in choice in giving birth to a child , living. The main job includes the main body of a book: (1) start with valve nature being applied or used universally this several kinds, structure , principle carry out the standard analysing , summing up their main part on their various. Range carries out (2) pair of the valve being applied or use
