Description
Technical field
The utility model relates to and a kind ofly has reliably spacing full flow guide type list plate valve, belongs to gate valve technical field.
Background technique
Plate valve is widely used in the gas of department and the conveyings of liquid medium such as chemical industry, water power, metallurgy, urban construction.Plate valve fluid resistance is very little, and sealing surface is little by washing away and corroding of medium, and switch valve is laborsaving, opens and closes moment and is only 1/2 of common valve, can reach light open and close valve.Plate valve with pod apertures is arranged on pipeline also can carry out pigging by direct wiper, but, the plate valve of the band pod apertures of traditional design, manufacturing procedure is complicated, manufacture cycle is very long, required precision is harsher than traditional valve, and often find after parts, during valve wide open position, flashboard pod apertures cannot be positioned on same axis with valve body two passage, cause any perpendicular to the Fei Deng circular section, cross section on valve passage axis, need of production is dismantled again, analyze, maintenance part, manufacture cycle is longer, cost of labor is very expensive, its application area is greatly limited.
Model utility content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of and has reliably spacing full flow guide type list plate valve.
Technological scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of have reliably spacing full flow guide type list plate valve, comprise: valve body, valve gap, valve rod, flashboard, valve seat orifice, stop bit parts, stroke limit convex shoulder, pod apertures, described body top arranges valve gap, described valve rod is connected with flashboard through valve gap, and valve rod and flashboard joint are provided with stop bit parts; Described valve seat orifice top is provided with stroke limit convex shoulder; Described stop bit parts match with stroke limit convex shoulder position, for controlling flashboard axial position; Described flashboard is provided with pod apertures.
Described stop bit parts comprise: upper seam, lower seam, and described stop bit component top is set to seam, and stop bit feature bottom is set to lower seam; Described upper seam matches with bottom valve gap, for controlling valve rod upward stroke; Described lower seam matches with stroke limit convex shoulder, for controlling flashboard axial position.
Also comprise: guide mechanism, described valve body madial wall is provided with guide mechanism, matches with flashboard sidewall in described guide mechanism position, for controlling flashboard lateral attitude.
Also comprise: indicating device, described valve stem tip is provided with indicating device, for the convenient running position observing flashboard.
Preferably, described flashboard top is provided with T-slot, and described stem bottom is connected with T-slot on flashboard.
Preferably, described valve body is provided with two symmetrical valve seat orifice.
Beneficial effect: what the utility model provided a kind ofly has reliably spacing full flow guide type list plate valve, utilize valve own characteristic, axial, horizontal position-limit mechanism is set, during valve wide open, on valve rod, seam contacts with valve gap lower end surface, during valve closing, the stroke limit shoulder contact under valve rod in seam and valve seat orifice, carries out axial accurate limiting to valve rod; Meanwhile, guide mechanism is utilized to contact with flashboard sidewall, to the horizontal accurate limiting of flashboard.Can ensure that pod apertures at valve wide open position and valve body both sides port hole axis point-blank, namely the circular hole cross section such as be along the arbitrary section of passage vertical line, effectively ensure the pigging operation of energy transfer line.The design's structure is simple, strong operability, and assembling is simple, stroke adjustable, easy-to-operat, observation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is flashboard partial structurtes front views;
Fig. 3 is indicating device's structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of have reliably spacing full flow guide type list plate valve, comprise: valve body 1, valve gap 2, valve rod 3, flashboard 4, valve seat orifice 5, stop bit parts 6, stroke limit convex shoulder 7, pod apertures 8, described valve body 1 top arranges valve gap, described valve rod 3 is connected with flashboard 4 through valve gap 2, and valve rod 3 and flashboard 4 joint are provided with stop bit parts 6; Described valve seat orifice 5 top is provided with stroke limit convex shoulder 7; Described stop bit parts 6 match with stroke limit convex shoulder 7 position, for controlling flashboard axial position; Described flashboard 4 is provided with pod apertures 8.
Described stop bit parts 6 comprise: upper seam 61, lower seam 62, and described stop bit parts 6 top is set to seam 61, is set to lower seam 62 bottom stop bit parts 6; Described upper seam 61 matches with bottom valve gap 2, for controlling valve rod upward stroke; Described lower seam 62 matches with stroke limit convex shoulder 7, for controlling flashboard axial position.
As shown in Figure 2, also comprise: guide mechanism 9, described valve body 1 madial wall is provided with guide mechanism 9, and match with flashboard 4 sidewall in described guide mechanism 9 position, for controlling flashboard lateral attitude.
As shown in Figure 3, also comprise: indicating device 10, described valve rod 3 top is provided with indicating device 10, for the convenient running position observing flashboard.
Preferably, described flashboard 4 top is provided with T-slot, is connected bottom described valve rod 3 with T-slot on flashboard 4.
Preferably, described valve body 1 is provided with two symmetrical valve seat orifice 5.
Concrete usage mode is as follows: the handwheel on rotating drive mechanism, driving casing in driving mechanism makes valve rod move up and down, drive flashboard to move up and down along the Vertical direction of passage axis, rotate counterclockwise driving mechanism handwheel, the flashboard connected together with valve rod rises, valve channel is opened, fluid flows to the other end by one end of valve body, on the contrary, when rotating clockwise handwheel, flashboard declines, valve closing.During valve wide open, because upper seam contacts with valve gap lower end surface, and flashboard contacts with guide mechanism, effectively can ensure that valve is when fully open position, flashboard pod apertures and valve body both sides port hole axis are point-blank, namely the circular hole cross section such as to be along the arbitrary section of passage vertical line, effectively to ensure the pigging operation of energy transfer line.The stroke limit convex shoulder that valve seat orifice top is arranged, instantly, when seam and stroke limit shoulder contact, valve can be realized and close completely, valve stroke position accurately, is intuitively placed on valve top part by indicating device simultaneously, greatly easy-to-operat is observed, and accomplishes visual.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
