Abstract
The utility model relates to a quick-opening and quick-closing high-pressure valve which belongs to the field of a mechanical valve, which comprises a valve body (1), wherein a circular cavity of the upper part of the valve body is provided with a valve plug (5). The valve plug is pressed on a channel flow hole (13), and is connected with a valve rod (7) and is fixedly connected with a cover (6) of the valve plug. The utility model is characterized in that the cover of the valve plug is fixedly connected with a spring (10) of the valve plug. The time of opening and closing a motorized valve is less than 1 second by the adoption of the valve body, and the requirements of the industrial fields of a filling machine field, etc. are met.
Description
Technical field
The utility model belongs to the machinery valve field.
Background technique
At present the switching time of mortor operated valve is mostly greater than 5 seconds, thereby much both requiring the reliability height, requires time of switch valve to be lower than under 1 second the occasion again---such as filling machine, IC-card boiled water supplying system etc., can't use.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of changing up soon to close high pressure valve.
The purpose of this utility model is achieved in that to change up soon closes high pressure valve, comprise valve body (1), valve plug (5) is housed in the upper circular cavity of valve body, valve plug is pushed down channel capacity hole (13), be connected with valve rod (7) on the valve plug, be connected with valve plug lid (6) on the valve plug, it is characterized in that: cover affixed valve plug spring (10) at valve plug.
Be equipped with valve compressing tablet (9) on the described valve plug spring, be equipped with y-type seal ring (8) on the valve compressing tablet, be equipped with sealing gland (12) on the y-type seal ring.
Described valve plug spring (10) is assemblied in the valve pocket inside of valve body (1), contacts with flowing medium.This is under the situation of valve closing, guarantee valve can be under the very high situation of hydraulic pressure proper functioning; Avoided spring because the effect of hydraulic pressure moves upward, valve open, make valve under high pressure airtight not tight.
Described valve rod (7) is a cylindrical body that has tooth bar.
Be equipped with O RunddichtringO (11) between described sealing gland (12) and the valve body (1).
The beneficial effects of the utility model: adopt valve body of the present invention, satisfied the requirement of industrial fields such as filling machine less than 1 second the switching time that can use mortor operated valve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Among the figure: 1 valve body, 2 valve body threaded coupling inserts, 3 valve plug screws, 4 valve plug gland screw covers, 5 valve plugs, 6 valve plugs lid, 7 valve rods, 8Y RunddichtringO, 9 valve compressing tablets, 10 valve plug springs, 11O RunddichtringO, 12 sealing glands, 13 channel capacity holes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to accompanying drawing 1, change up soon and close high pressure valve, comprise valve body (1), valve body threaded coupling inserts (2) symmetry is embedded in the both sides of valve body, valve plug (5) is housed in the upper circular cavity of valve body, valve plug is pushed down channel capacity hole (13), affixed valve plug gland screw cover (4) on the valve plug, the valve plug gland screw puts and is equipped with valve plug screw (3), be connected with valve rod (7) on the valve plug screw, be equipped with valve plug lid (6) on the valve plug, valve plug covers and is equipped with valve plug spring (10), is equipped with valve compressing tablet (9) on the valve plug spring, is equipped with y-type seal ring (8) on the valve compressing tablet, be equipped with sealing gland (12) on the y-type seal ring, be equipped with O RunddichtringO (11) between sealing gland and the valve body.Valve plug spring (10) is assemblied in the valve pocket inside of valve body (1), contacts with flowing medium.
Course of action: under the normal state, valve is under the effect of spring, valve is in closed condition, in the time of need driving valve, can drive valve rod by external force (such as electric actuator) and move upward, when valve rod moves upward 2mm, because the diameter in channel capacity hole is bigger, so the flow of this moment is bigger, thereby required opening time of valve is very short.After external force was removed, because the effect of valve plug spring, in less than 1 second time, valve plug was just pushed down the channel capacity hole, had realized that the instantaneous of valve close.
Claims (5)
1, changes up soon and close high pressure valve, comprise valve body (1), valve plug (5) is housed in the upper circular cavity of valve body, valve plug is pushed down channel capacity hole (13), be connected with valve rod (7) on the valve plug, be connected with valve plug lid (6) on the valve plug, it is characterized in that: cover affixed valve plug spring (10) at valve plug.
2, according to claim 1 changing up soon closed high pressure valve, it is characterized in that: be equipped with valve compressing tablet (9) on the valve plug spring, be equipped with y-type seal ring (8) on the valve compressing tablet, be equipped with sealing gland (12) on the y-type seal ring.
3, according to claim 1 and 2 changing up soon closed high pressure valve, it is characterized in that: described valve plug spring (10) is assemblied in the valve pocket inside of valve body (1), contacts with flowing medium.
4, according to claim 1 changing up soon closed high pressure valve, it is characterized in that: described valve rod (7) is a cylindrical body that has tooth bar.
5, according to claim 1 changing up soon closed high pressure valve, it is characterized in that: be equipped with O RunddichtringO (11) between sealing gland and the valve body.
