Abstract
The utility model relates to a remote control valve, which consists of a valve seat (11), a valve core (5), a seal ring (4), and a return spring (9). The utility model is characterized in that the cone-frustum shaped sealed valve core (5) is arranged in the valve seat (11) which is provided with two main channels, and a single action low pressure cylinder (I) consisting of the valve seat (11), a control connector (2) with holes, and a control piston (3) is arranged at one end of the valve core (5); a stop mechanism (II) consisting of the valve core (5), the valve seat (11), the return spring (9), a return piston (8) and a return seat (12) is arranged at the other end of the valve core (5). The structure of the control valve is simple, the operation is secure and convenient, and not only the remote control can be realized, but also the remote automatic control can be realized.
Description
Technical field
The present invention relates to a kind of Remote control valve, is a kind of new bi-bit bi-pass stop valve, belongs to Fluid valve device class.
Background technique
Gas cylinder on the existing all kinds of aviations inflation special cars all adopts hand stop valve, inconvenient operation not only, and working life is short, and Security is also poor.
Technology contents
The purpose of the present utility model provides a kind of stop valve new, practicable remote pneumatic control, be used for gas cylinder, the gas cylinder of equipping on aviation oxygen dispenser, Nitrogen filling vehicle, the air-conditioned car for example, not only require easy to operate, safe in utilization and can also realize telecontrol and automatically control.
This process control valve is made up of valve seat (11), spool (5), seal ring (4), seal ring (7) and return spring (9), it is characterized in that: be provided with the spool (5) that the cone table shape sealing is being set in the valve seat (11) of two main passages, an end of this spool (5) is being provided with the single-acting low-pressure cylinder of being made up of valve seat (11), control joint with holes (2) and control piston (3) (I); The other end of spool (5) then is being provided with the disabling mechanism of being made up of spool (5), valve seat (11), return spring (9), return piston (8) and return seat (12) (II).
The invention has the advantages that it is simple for structure, long service life, Security is good, does not also have leakage when bearing pressure and reaching 40Mpa, and can realize telecontrol and control automatically.
Description of drawings
Accompanying drawing 1,2 is the utility model structural representation.
Among the figure: 1. gas cylinder joint 2. control joints 3. control pistons 4. seal rings 5. spools 6. seal muzzles 7. seal rings 8. return pistons 9. return springs 10. joints 11. valve seats 12. spring seat I. single-acting low-pressure cylinder II. disabling mechanisms.
Embodiment
This Remote control valve as shown in the figure, form by valve seat (11), spool (5), seal ring (4), (7) and return spring (9), that the inner chamber of its valve seat (11) is being provided with is shaft-like, the spool (5) of taper type, one end of this shaft-like spool (5) is being provided with porose control joint (2), the single-acting low-pressure cylinder I that control piston (3) is formed, the other end of valve seat (5) then is being provided with valve seat (11) and is being connected, and the disabling mechanism of being made up of spring seat (12), return spring (9) and return piston (8).
The working principle of this Remote control valve is as follows:
After valve seat (5) was connected by steel gas cylinder joint and gas storage cylinder, two main passages by spool (5) closure just become used the gas main passage.In case in the time of need emitting the valuable gases in the steel gas cylinder, start source of the gas as long as start the control that links to each other with control joint (2), as long as this pressure that starts source of the gas is about 0.6-3Mpa.Owing to start the effect of source of the gas, the spool (5) that control piston (3) in the single-acting low-pressure cylinder I promotes in the valve seat (11) moves right, at this moment connect with the gas main passage, simultaneously because moving to right of spool (5) also moves to right return piston (8) simultaneously, compression retracteding position spring (9).
And when needs are closed the main passage, as long as only close the startup source of the gas, because the control piston (3) in the left side single-acting low-pressure cylinder I loses pressure, being compressed spring and promptly can stretching in the disabling mechanism II of the right so, promote return piston (8) simultaneously and spool (5) is moved to the left, spool (5) is got back to again closed the position, main passage; And this moment, spool (5) left end also arrived initial state with the control piston pushing tow.
Use this valve not only can realize nearly remote opening and close, also can realize remote auto control.
