Description
Technical field
The utility model relates to a kind of valve, and especially a kind of structure is simple, and between flap and valve seat, friction factor is little, the gate valve of long service life.
Background technique
Gate valve is one of conventional valve of the field of engineering technology such as petrochemical industry, rock gas, urban pipe network.At present, the gate valve that market and data occur primarily of valve body, valve seat, valve plate, drive valve plate driving mechanism and connect the valve rod of driving mechanism and valve plate, valve body is provided with medium inlet passage and medium flow pass, by connecting passage conducting between medium inlet passage and medium flow pass, driving mechanism drives valve plate elevating movement, thus realize conducting and the closedown of connecting passage, adopt metal hard-sealing or soft seal between valve seat and flashboard.Wherein, prop open type gate valve is widely used in some petrochemical industry purposes, its principle is that the independent flashboard pin of dependence two is connected to above connecting plate, when valve opening, rotate handwheel, linking mechanism is driven upwards to promote by valve rod, when valve rod drives connecting plate when driving flashboard upwards to do enhancing action, the conical surface below valve body boss and flap is departed from, at this moment the Compress Spring arranged between two flaps can draw two flaps to spindle of valve body line direction, when reaching certain distance, the flap boss that flap is arranged below can limit valve distance of opening suitable for reading, valve is not rubbed with sealing surface of seat in opening process, then security improvement, until standard-sized sheet, this spring that utilizes shrinks flap, the friction between flap and valve seat can well be reduced, but due to the physical property of spring, the degree of fatigue of spring can be caused in the drawing process gone round and begun again to increase, the elastic force of spring is declined, cannot well stretch to gate valve, the working life of valve is shortened.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is simple that the utility model provides a kind of structure, and between flap and valve seat, friction factor is little, the gate valve of long service life.
It is a kind of bracing type seal gate valve that the utility model solves the technological scheme that its technical problem adopts: include valve body, valve seat, valve plate, the driving mechanism of drive valve plate and the valve rod of connection driving mechanism and valve plate, valve body is provided with medium inlet passage and medium flow pass, by connecting passage conducting between medium inlet passage and medium flow pass, the both sides that connecting passage is positioned at medium inlet passage and medium flow pass are provided with valve seat, driving mechanism drives valve plate elevating movement, be in form in connecting passage and with valve seat from described valve plate and seal, described valve plate is oppositely arranged by two and laterally can blocks the dividing plate that medium circulates in valve body and form, be respectively the first dividing plate and second partition, described first dividing plate and second partition corresponding surface are in correspondence with each other equipped with pull unit, described pull unit is several magnetic patch be movably connected on corresponding surface, magnetic patch on described first dividing plate is oppositely arranged with the magnetic patch on second partition respectively, magnetic patch on described first dividing plate is contrary with the magnetic patch magnetic on second partition.
After have employed said structure, compared with gate valve in the past, instead of spring with magnet.Overcome single spring in the motion gone round and begun again, produce the problem of mechanical fatigue, and several magnetic patch also considerably increase the validity of motion, the maintenance degree of magnetic patch also more for convenience.
As further improvement of the utility model, described dividing plate is provided with the standing groove placed for magnetic patch, and the size and shape of described standing groove is consistent with magnetic patch, and magnetic patch can be tight with on this standing groove.
After have employed said structure, the setting of standing groove, can make magnet be positioned in this groove, and be convenient to taking and changing of magnetic patch, the maintenance for the later stage brings larger convenience.
As further improvement of the utility model, described first dividing plate and second partition are interval with three magnetic patch from top to bottom, described standing groove is also provided with magnet control piece, described magnet control piece is open and close door, be provided with the groove that pushes for open and close door turnover in described standing groove, described in push the shape of groove and open and close door and size consistent.
After have employed said structure, the setting of push groove and open and close door, can protect the magnetic patch temporarily not needing to use on the one hand, and can regulate the suction between magnetic patch according to demand.
Accompanying drawing explanation
Figure 1 shows that the self-contained figure of bracing type seal gate valve.
