Description
Technical field
The present invention relates to a kind of valve processing and use mold, relate in particular to mouthful flange drilling mold in a kind of rubber gate valve body.
Background technology
Gate valve is an indispensable control appliance in the water system, is mainly used in pipe network, pump house and filter tank etc. and locates.Gate valve mainly is made up of valve body, valve gap, valve rod, valve stem nut, the flashboard that is connected with valve rod, valve seat, filler assembly and transmission device.Valve body is the main body of gate valve; Be valve gap is installed, lays valve seat, is connected the strength member of pipeline; Valve body and valve gap are connected to form withstand voltage cavity through flange, and valve rod is connected with valve stem nut or transmission device, play a part carry-over moment and open and close flashboard; Flashboard is done elevating movement and is reached the keying purpose along sealing surface of seat under the drive of valve rod.Gate valve is a kind of of block valve class, is used for connecting or blocking the medium in the pipeline, and being applicable to does not usually need frequent keying, and keeps the operating mode of flashboard standard-sized sheet or full cut-off.Gate valve is not suitable for to be regulated or the throttling use, and for swiftly flowing medium, flashboard can cause the vibration of gate under part unlatching situation, and vibration possibly damage the sealing surface of flashboard and valve seat, and the throttling meeting makes flashboard suffer the erosion of medium.In view of above shortcoming; Adopt the soft sealing gate valve of the full encapsulate of flashboard to become the industry development main flow; Require specification to select the soft seal valve as far as possible for use with lower valve in " equipment choosing and operational management " technical measures of China's " urban water supply industry 2010 technological progress development plan and the year two thousand twenty long-range objectives ", and metal pedestal gate sealing valve old on the pipe network is progressively changed at DN600.Rubber seal is the main soft seal form of mesolow valve, and the performance of rubber, the hermetically-sealed construction of valve, contact element precision are the principal elements of influence sealing.The rubber gate valve adopts the full encapsulate of flashboard directly and the form of valve body contact seal; Slideway moves up and down the realization valve opening or closes the encapsulate flashboard along the body cavity both sides; The exposure level of encapsulate valve plate and valve body sealing surface in the precision of flashboard and valve body sealing surface, smoothness and the assembling process directly influences the sealing effectiveness of valve.Valve body is connected through valve flange and bonnet flange with valve gap, must on two flanges, hole before the assembling, and mouthful flange drilling must be with respect to slideway center and valve body sealing surface center symmetry in the valve body; Mouthful boring must be with respect to valve rod hole center symmetry in the valve gap, and these two symmetries have just guaranteed that valve gap valve rod hole center overlaps with valve body slideway center and valve body sealing surface center; Guaranteed to be in the middle of the valve body both sides sealing face after the valve plate assembling; The rubber even contact, thus make both sides sealing even, do not have and leak.The mold of mouthful flange hole mainly comprises the identical bushing plate of size shape and middle mouthful of flange profile, is inlaid in drill bushing and 2-3 alignment pin on the bushing plate in existing processing gate valve body and the valve gap; Its method of operating is, with bushing plate and valve body or bonnet flange profile and center line aligned and fixing, directly processing; Because the positioning reference precision is not high; Cause valve body two sealing surface symmetrical centre not overlap, can not be positioned in the middle of valve body two sealing surfaces after making valve plate assembling, cause rubber seal asymmetric, inhomogeneous with valve gap valve rod hole center; Valve leak, yield rate is lower.
Summary of the invention
Main purpose of the present invention is to the problems referred to above; Mouthful flange drilling mold in mouthful flange drilling mold and the corresponding a kind of valve gap is provided in a kind of rubber gate valve body; Make in the valve body mouthful flange drilling with respect to slideway center and valve body sealing surface center symmetry, in the valve gap mouthful boring with respect to valve rod hole center symmetry, thereby assurance valve gap valve rod hole center overlaps with valve body slideway center and valve body sealing surface center; Guaranteed to be in the middle of the valve body both sides sealing face after the valve plate assembling; Rubber is closely contact evenly, thereby makes both sides sealing evenly tight, does not have and leaks.
The technical solution adopted for the present invention to solve the technical problems is:
