Abstract
Provided is a novel pneumatic adjusting valve. The problems that after an existing adjusting valve is used, a cushion block becomes brittle and the sealing performance is reduced are mainly solved. The novel pneumatic adjusting valve is characterized in that a cooling cavity (5), a liquid inlet (6) and a liquid outlet (7) are formed in a valve rod (2), the liquid inlet (6) and the liquid outlet (7) are communicated with the cooling cavity (5), padding (8) is arranged between the valve rod (2) and a valve cover (3), a padding pressing plate (9) is arranged on the valve cover (3), and a padding pressing sleeve (10) is arranged between the padding pressing plate (9) and the padding (8). The cooling cavity is formed in the valve rod, cooling liquid in the cooling cavity can fast absorb heat emitted in the operation process of the valve rod, the cushion block is effectively protected, the sealing performance of the valve is good, and the service life is long.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of novel pneumatic modulating valve.
Background technique
Modulating valve is the controlling component in fluid delivery system, has water conservancy diversion, dams, adjusting, throttling, prevents the functions such as refluence, shunting or overflow pressure relief.How the valve rod of modulating valve is connected with cylinder, so that it controls spool fast open, keying is closed.This valve is in the time that valve rod frequency of okperation is higher, and temperature arrising caused by friction between valve rod and filler, causes filler below cushion block to become fragile, and affects valve seal.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of novel pneumatic modulating valve, has mainly solved existing modulating valve after using, and cushion block becomes fragile, the problem that sealing declines.
The technological scheme that the utility model adopts is: a kind of novel pneumatic modulating valve, comprise valve body, valve rod, valve gap, in described valve body, be provided with valve seat, in described valve rod, be provided with cooling chamber, liquid entering hole, liquid outlet, described liquid entering hole, liquid outlet are communicated with cooling chamber, between described valve rod and valve gap, be provided with filler, described valve gap is provided with hold-down grid, between described hold-down grid and filler, is provided with filler pressing sleeve.
Described valve gap is provided with standing groove, and described filler and filler pressing sleeve are arranged in standing groove, and described filler pressing sleeve end is exposed standing groove and contacted with hold-down grid, and described hold-down grid is fixed by screw and valve gap.
In described valve body, be provided with sleeve, described sleeve one end contacts with valve body, and the other end contacts with valve gap.
Between described valve gap and filler, be provided with cushion block.
Described sleeve and the junction point of valve body are provided with pad.
The beneficial effects of the utility model are: be provided with cooling chamber, the heat distributing when the cooling liquid in cooling chamber can absorb valve rod operation fast, has protected cushion block effectively, and valve seal is good, long service life.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
If Fig. 1 is in conjunction with as shown in Fig. 2 to 3, a kind of novel pneumatic modulating valve, comprise valve body 1, valve rod 2, valve gap 3, in described valve body 1, be provided with valve seat 4, in described valve rod 2, be provided with cooling chamber 5, liquid entering hole 6, liquid outlet 7, described liquid entering hole 6, liquid outlet 7 are communicated with cooling chamber 5, between described valve rod 2 and valve gap 3, are provided with filler 8, described valve gap 3 is provided with hold-down grid 9, between described hold-down grid 9 and filler 8, is provided with filler pressing sleeve 10.
Described valve gap 3 is provided with standing groove 31, and described filler 8 is arranged in standing groove 31 with filler pressing sleeve 10, and described filler pressing sleeve 10 ends are exposed standing groove 31 and contacted with hold-down grid 9, and described hold-down grid 9 is fixing by screw and valve gap 3.Install firmly, filler can not leak outside.
In described valve body 1, be provided with sleeve 11, described sleeve 11 one end contact with valve body 1, and the other end contacts with valve gap 3, easy installation and removal.
Between described valve gap 3 and filler 8, be provided with cushion block 12.Guarantee mechanism's sealing, prevent dielectric leakage.
Described sleeve 11 is provided with pad 13 with the junction point of valve body 1.Pad 13 can effectively reduce the impact force of spool to sleeve 11, protection sleeve 11, extending mechanism working life.
The concrete use of the utility model is as follows: when work, valve rod 2 is under the effect of driving mechanism, and filler 8 slippages also produce heat relatively; cooling liquid in valve rod 2 cooling chambers 5 can absorb heat fast; reduce valve rod 2 temperature, protected cushion block 12, improved mechanism's sealing.
The beneficial effect of model utility is: be provided with cooling chamber, the heat distributing when the cooling liquid in cooling chamber can absorb valve rod operation fast, has protected cushion block effectively, and valve seal is good, long service life.
