Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of push-pull valve.
Background technique
Sealing contacts the valve plate upper and lower surfaces of existing push-pull valve with lower cover plate with seal ring respectively; In use; Because the frequent folding of valve plate causes the friction with seal ring, lower cover plate, in the course of time, the valve plate upper and lower surfaces just has the gap respectively and between the seal ring, lower cover plate; Poorly sealed, as to cause medium to be revealed problem.This just needs to change seal ring and/or valve plate, and it is big not only to change difficulty, and cost is high.
The model utility content
The utility model provides a kind of and can regulate the valve plate upper and lower surfaces is in the sealing contact condition respectively in the course of the work all the time with seal ring and lower cover plate push-pull valve in order to solve deficiency of the prior art.
For solving the problems of the technologies described above; The utility model adopts following technological scheme: a kind of push-pull valve; Comprise and horizontally disposedly in upper cover plate that valve body, valve body top be provided with, the corresponding up and down connecting passage that is provided with of lower cover plate, upper cover plate and lower cover plate that the valve body bottom is provided with, the valve body be used to open and close the valve plate of connecting passage and be connected the valve rod that stretches out valve body with valve plate; Connecting passage place suitable for reading is provided with the seal ring that is connected with upper cover plate; The seal ring lower end surface contacts with the sealing of valve plate upper surface, and connecting passage end opening place is provided with the object-discharging pipe joint that is connected with lower cover plate, is provided with valve rod sealing assembly between valve rod and the valve body; Be provided with two slideways parallel in the said valve body with valve plate moving direction; Article two, slideway lays respectively at the left and right sides, valve plate below, and the valve plate lower surface left and right sides is respectively equipped with the slide rail that slides and be sealed and matched with adjacent slideway, and lower cover plate is provided with and is used for the modulating valve plate seal assemblies that roof pressure slideway upwards makes slideway and slide rail slip and is sealed and matched.
Said modulating valve plate seal assemblies comprises the cylindrical shell that is vertically welded on the lower cover plate, be located in the cylindrical shell and the upper end penetrates lower cover plate the make progress push rod of roof pressure slideway and the rotary cover with internal thread; Cylindrical shell bottom excircle is provided with outside thread and is threaded with rotary cover, is provided with the pad that cooperates with push rod lower end surface roof pressure in the rotary cover.
The face of being slidingly matched between said slide rail and the slideway is a fixing structure.
Adopt technique scheme; Slide rail is set and in valve body, is arranged at the slideway that slide rail is slidingly matched in valve plate lower surface both sides; Through operating regulation valve plate black box slideway is cooperated all the time with the slide rail slipper seal; Valve plate is slided in the course of the work all the time and sealing contact with the seal ring lower end surface, thus solve push-pull valve in use between long poorly sealed problem afterwards.
The modulating valve plate seal assemblies adopts the rotary cover of manually screwing to come the upwards mode of jacking push rod, and in rotary cover, adds pad, makes to regulate to have progressively and have continuable effect.
The face of being slidingly matched between slide rail and the slideway is a fixing structure, not only plays good slide-and-guide effect, has more good sealing effect.
The utility model is reasonable in design, simple in structure, easy and simple to handle, has practiced thrift the cost of changing seal ring and/or valve plate, has fully prolonged the working life of push-pull valve, and is practical, is easy to apply.
