Abstract
The utility model discloses a sliding seal device, which comprises a shell, a pressing plate indicating device and a seal plate, wherein the shell is provided with a seal plate sliding cavity; the seal plate is arranged in the seal plate sliding cavity; and the lower end of the seal plate extends out of the seal plate sliding cavity. The pressing plate indicating device comprises an indicating rod, a pressing plate and a spring, wherein the indicating rod and the pressing plate are vertical to each other to form a whole; the spring is sheathed onto the indicating rod; the pressing plate indicating device is arranged in the seal plate sliding cavity and is located at the upper end of the seal plate; and the upper end face of the seal plate is tightly pressed by the pressing plate. The upper part of the seal plate sliding cavity is sealed by a cover plate, and the indicating rod passes out from an indicating rod hole on the cover plate. The indicating rod is used for indicating the consumption of the seal plate. The lower end of the seal plate is directly contacted with a sliding part, and the lower end face of the seal plate is tightly fitted with the sliding part by the pressing force of the spring so as to seal the sliding part. The seal device is designed to be modular, and module units with corresponding dimensions can be selected according to the requirement to form the whole seal device. The sliding seal device has a simple structure and a good seal property and is capable of adapting to high-temperature working conditions.
Description
Technical field
The utility model relates to a kind of sliding sealing device, relates in particular to a kind of sliding sealing device that is applicable to cooling machine pushing device.
Background technique
Cooling machine pushing device is in order to destroy the inner accumulation of cooling machine " snowman ", improve the cooling machine to the cooling effect of grog and a kind of equipment that occurs, its working principle is generally by oil hydraulic cylinder and drives push rod, relies on the to-and-fro motion of push rod to destroy inner " snowman " who piles up of cooling machine.The appearance of pushing device provides a great help for the formation of avoiding " snowman " in the cooling machine, but problem of the thing followed to be the cooling machine inner abominable operating mode has proposed very big test for the sealing of push rod.The pushing device of making a general survey of in the past is not very desirable for the processing of push rod seal problem, and What is more does not simply take any seal approach.This grog particle that can cause cooling machine inside is along with spraying the working environment of severe exacerbation pushing device platform the slit of high temperature gas flow between push rod and housing.
The model utility content
In order to solve the problems referred to above that existing cooling machine pushing device push rod seal aspect exists, the utility model technology has proposed a kind of sliding sealing device that adapts to worst hot case, simple in structure, good seal performance.
For achieving the above object, the utility model has adopted following technological scheme: a kind of sliding sealing device comprises housing, clamp finger showing device, sealing plate; It is characterized in that: described housing is provided with the sliding chamber of sealing plate, and the sliding chamber of sealing plate connects housing, and sealing plate places in the sliding chamber of sealing plate, sealing plate the lower end stretch out outside the sliding chamber of sealing plate;
Described clamp finger showing device is made of indicating arm, pressing plate and spring, and indicating arm is vertical with pressing plate to constitute one, and spring housing is contained on the indicating arm, and the clamp finger showing device places in the sliding chamber of sealing plate and is positioned on the sealing plate, pressing plate compress sealing plate the upper-end surface;
Seal with cover plate on the top in the sliding chamber of sealing plate, and cover plate is provided with the indicating arm hole, and indicating arm is passed by the indicating arm hole.
Described sealing plate is a hard antifriction lubriation material sealing plate.
Described hard antifriction lubriation material is graphite, teflon or powdered metallurgical material.
To the convex edge, sealing plate was an inverted "convex" shape in lower end, the sliding chamber of described sealing plate was provided with.When sealing plate ledge touch lower end, the sliding chamber of sealing plate interior during to the convex edge, sealing plate just no longer continues to consume, this structural design avoided sealing plate wear and tear fully and the pressing plate that causes contacts with the direct of movable part, can judge whether that according to the position of indicating arm needs change sealing plate.
Described indicating arm is as the guide rod of spring, and be used to refer to sealing plate consumption, when indicating arm drops to some height, represent to change sealing plate.Described sealing plate lower end directly contacts with slider, relies on the impacting force of spring to make sealing plate lower end surface and slider fit tightly the sealing that realizes slider; Described spring housing is contained on the indicating arm, is used for clamping platen; The effect of pressing plate is that the impacting force with spring is applied on the sealing plate upper-end surface uniformly, makes sealing plate with the slider even contact, improves sealing effect.Seal arrangement is modular design, can choose the modular unit of correspondingly-sized as required and form a complete seal arrangement.
Simple in structure, the good seal performance of the utility model adapts to worst hot case.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, sliding sealing device of the present utility model comprises housing 1, clamp finger showing device, sealing plate 5.Described housing 1 is surrounded by steel plate, by Bolt Connection, forms the sliding chamber of sealing plate of up/down perforation between the steel plate.Sealing plate places in the sliding chamber of sealing plate, sealing plate the lower end stretch out outside the sliding chamber of sealing plate.To the convex edge, sealing plate was an inverted "convex" shape in lower end, the sliding chamber of sealing plate was provided with.When the edge of sealing plate projection touch lower end, the sliding chamber of sealing plate interior during to the convex edge sealing plate just no longer descend, this structural design avoided sealing plate wear and tear fully and the pressing plate that causes contacts with the direct of movable part, also should in time change sealing plate in this case certainly.
The clamp finger showing device is made of indicating arm 2, pressing plate 4 and spring 3, and indicating arm is vertical with pressing plate to constitute one, and spring housing is contained on the indicating arm, and the clamp finger showing device places in the sliding chamber of sealing plate and is positioned on the sealing plate, pressing plate compress sealing plate the upper-end surface.Seal with cover plate 6 on the top in the sliding chamber of sealing plate, and cover plate is provided with the indicating arm hole, and indicating arm is passed by the indicating arm hole.
Indicating arm 2 is as the guide rod of spring 3, and is used to refer to the consumption of sealing plate 5, represents change sealing plate when indicating arm 2 drops to some height; Sealing plate 5 can adopt graphite, teflon and powdered metallurgical material etc., and sealing plate 5 lower end surfaces directly contact with slider 7, rely on the impacting force of spring 3 make sealing plate lower end surface and slider fit tightly the sealing that realizes slider.Spring 3 is sleeved on the indicating arm 2, is used for clamping platen 4; The effect of pressing plate 4 be the impacting force with spring 3 be applied to uniformly sealing plate on the upper-end surface, make sealing plate lower end surface and slider even contact, improve sealing effect.
The utility model sliding sealing device, its housing is linked together by the mode and the fixing frame 8 of Bolt Connection or welding.Seal arrangement is modular design, and the modular unit that can choose correspondingly-sized is as required formed a complete seal arrangement and realized sealing to slider.In the engineering of slider work, rely on the sealing of finishing slider that fits tightly between sealing plate and the slider, improve the working environment of pushing device platform.
