Abstract
The utility model relates to a valve, in particular to a pneumatic hard seal quick switching valve. A seat sealing ring (2), a valve seat (3), a core rod (4), a valve sleeve (5), a cover sealing ring (6) and a valve cover (7) are arranged in an inner hole of a valve body (1); the core rod (4) is sleeved into the valve sleeve (5); the valve cover (7) is fastened with the valve body (1), and a support (21) is arranged on the top of the valve cover (7); a filler (11), a gasket (16) and a pressing plate (17) are arranged on the core rod (4); and the upper end of the core rod (4) is connected with a driving device. The quick switching valve thoroughly solves various problems of the conventional quick switching valve, is widely applied in various industries, and is particularly applied to quick automatic control of a high-temperature medium.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of pneumatic hard sealing acceleration switching valve.
Background technique
In industries such as oil, chemical industry, food, light industrys, because the specific (special) requirements of concrete operating mode need open and cut off the medium in the pipeline usually fast, have inaccessible quick unlatching of valve and cut-out now, there is the problem of reliability, poor stability.Pneumatic hard sealing acceleration switching valve is as one of critical valves of specific position, and ubiquity the interrupted problem of the slow or two-way speed of switching speed at present, leak in also having serious, filler leaks outside, be prone to stuck and repair difficult etc.Like the control of the blowback air in the Melamine Production, badly influenced the utilization efficiency of filter, cause output to descend.
Summary of the invention
The utility model provides a kind of pneumatic hard sealing acceleration switching valve, guide structure and coated with hard alloy in the employing, and actuator selects high thrust bidirectional high speed cylinder for use, is equipped with high flow directional control valve and rapid escape valve again, and complete machine speed can reach two-way 0.5 second.Sealing surface weld deposit department titanium Lay cemented carbide, and grind through special process, zero leakage guaranteed; Use 100,000 times non-maintaining, the quick disassembly-type valve seat of cage need not special tool; Make the maintenance of valve no longer difficult, thoroughly solved the variety of issue of present acceleration switching valve.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Pneumatic hard sealing acceleration switching valve; Be provided with a seal ring, valve seat, core bar, valve pocket, lid seal ring and valve gap in valve body inner bore; Described core bar is inserted in the valve pocket, and valve gap and valve body tighten up, and the valve gap top is provided with support; Core bar is provided with filler, lining ring and pressing plate, and the core bar upper end is connected with drive unit.
As preferably, described drive unit is the gas piston cylinder.
As preferably, described filler has four layers, is last filler, spacer, middle filler and following filler from top to bottom.
As preferably, there is screw to fix on described valve gap and the pressing plate respectively.
The utlity model has following advantage:
1. adopt and go up guide structure and coated with hard alloy, and through the processing of highi degree of accuracy outer rim grinding machine, surface finishment is high, when core bar slided up and down, surface friction drag was little, so the moment of open and close is little, and steadily opening and closing fast of valve.
2. drive unit is selected high thrust bidirectional high speed cylinder for use, is equipped with high flow directional control valve and rapid escape valve again, and complete machine speed can reach two-way 0.5 second.
3. sealing surface weld deposit department titanium Lay cemented carbide, and grind through special process guaranteed zero leakage, and wearing and tearing is little in the using process, and sealing is reliable, use 100,000 times non-maintaining.
4. the quick disassembly-type valve seat of cage need not special tool, can easily take valve gap apart, extracts parts place under repair or replacings such as core bar, seal ring, valve pocket out, makes the maintenance of valve no longer difficult.
Description of drawings
Fig. 1 is the embodiment's of the described pneumatic hard sealing acceleration switching valve of the utility model a structural representation.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1.
Embodiment
Pneumatic hard sealing acceleration switching valve; As shown in Figure 1: be provided with a seal ring 2, valve seat 3, core bar 4, valve pocket 5, lid seal ring 6 and valve gap 7 at valve body 1 endoporus, described core bar 4 is inserted in the valve pocket 5, and valve gap 7 tightens up with valve body 1; Valve gap 7 tops are provided with support 21; Core bar 4 is provided with filler 11, lining ring 16 and pressing plate 17, and core bar 4 upper ends are connected with drive unit 22, and drive unit 22 is the gas piston cylinder.
During the utility model switch motion, through the direction that solenoid valve adjustment pressure air gets into cylinder, during the cylinder upper cover ventilation, piston moves upward, and drives core bar 4 and upwards slides valve wide open; In lower cover of air cylinder when ventilation,, piston moves downward, and east, road core bar 4 is to lower slider, the valve complete shut-down.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
