Abstract
The present invention relates to a controllable automatic switch valve which comprises a valve body (14) and a cover (13). The present invention is characterized in that a piston group formed from an upper piston (4)and a lower piston (2) in positions corresponding to a valve through hole (15) in the valve body (14); the upper piston (4)and the lower piston (2) are coaxially connected by a valve rod (3); a hollow flow channel is formed in the valve rod (3), and the upper end of the hollow flow channel is sheathed with a flow guiding pipe (5); the other end of the flow guiding pipe (5) penetrates a valve cover (13) and is closed through a control valve (9) to open a valve through hole (15), or is communicated with a piston cavity (12) through the flow channel of the control valve (9) and downwards pulls the piston group to close the valve through hole (15). The present invention is suitable for controlling a valve with large flow to switch on or off by using less force, and provides possibility for remotely remote-controlling and operating valves with large flow and realizing automatic operation in severe work environment.
Description
Technical field:
The invention belongs to valve, be specifically related to a kind of controllable self-generating valve by the fluid effect.
Background technique:
In the known technology, the keying of valve adopts spiral to promote usually, and its exposed component is many, under the situation of work under bad environment, and the easy-to-rust clamping stagnation.And it is by manual operation, promotes effort, is difficult for realizing the long-distance remote control operation.The technological scheme that Chinese patent ZL93233727.9 discloses is a kind of " nothing leak outside laborsaving logistics switch valve ", it adopts the fluid passage is set on valve body, make that the valve body processing technology is difficult to realize, and trace is adjusted nearly 4 of control valves, not only make operation too complicated, respective valves mechanism is numerous and jumbled, influences mechanism's operational reliability.Simultaneously, the valve body openings is more, and cause easily and leak,
Summary of the invention:
The purpose of this invention is to provide a kind of pressure effect that utilizes self fluid, the automatic on-off valve, mechanism is simply ingenious, and reliable operation opens and closes controllable self-generating valve freely.
The present invention takes following technological scheme.
Controllable self-generating valve comprises valve body, valve gap, position corresponding to valve port in the valve body is provided with the piston set of being made up of upper piston and lower piston, upper piston links so that valve rod is coaxial with lower piston, establish the hollow fluid passage in the valve rod, hollow fluid passage upper end suit honeycomb duct, honeycomb duct the other end break-through valve gap are closed by control valve and Open valve through hole or be communicated with piston cavity through the control valve fluid passage and time push piston group and throttle down through hole.The planar circumferential area of upper piston is greater than the planar circumferential area of lower piston.
The present invention has tangible technique effect compared to existing technology.Owing to used the pressure of fluid self dexterously, make the keying of valve open freely, play the effect of " one or two group is very heavy ".Also be long-distance remote control operation large-capacity valve door, realize that the automation mechanized operation under the abominable working environment provides possibility.Functional unit is small and exquisite simultaneously, expose portion is few, long working life.Outturn sample of the present invention is on probation through industry, and effect is very desirable.
Description of drawings:
Accompanying drawing is the controllable self-generating valve sectional structure chart
Among the figure, the 1-flap, the 2-lower piston, the 3-valve rod, the 4-upper piston, the 5-honeycomb duct, the 6-fluid enters the hole, 7-control panel, 8-valve handle, 9-control valve, 10-fluid intercommunicating pore, 11-tap hole, 12-piston cavity, 13-valve gap, 14-valve body, 15-valve through hole.
Embodiment:
Below in conjunction with accompanying drawing the present invention is specifically described.Embodiment is used for illustrating of the present invention, rather than the present invention is imposed any restrictions.
Controllable self-generating valve comprises valve body 14, valve gap 13, position corresponding to valve through hole 15 in the valve body 14 is provided with the piston set of being made up of upper piston 4 and lower piston 2, upper piston 4 and lower piston 2 are with valve rod 3 coaxial linking, establish the hollow fluid passage in the valve rod 3, hollow fluid passage upper end suit honeycomb duct 5, honeycomb duct 5 the other end break-through valve gaps 13 are closed by control valve 9 and Open valve through hole or be communicated with piston cavity 12 through control valve 9 fluid passages and time push piston group and throttle down through hole 15.
The planar circumferential area of upper piston 4 is greater than the planar circumferential area of lower piston 2.
Working principle of the present invention is such, and the valve handle 8 when rotating control valve 9 makes control panel 7 sealing fluids enter hole 6, and piston cavity 12 is communicated with atmosphere by fluid intercommunicating pore 10, tap hole 11.At this moment, fluid pressure action is in flap 1, and the piston set that the while pushing tow is made up of lower piston 2 and upper piston 4 is up, relief valve through hole 15, and fluid flows.Micro fluid in the piston cavity 12 can be flowed out outside the valve by intercommunicating pore 10 and tap hole 11.
When the valve handle 8 that rotates control valve 9, drive control panel 7 and turn to fluid when entering hole 6 and being communicated with fluid intercommunicating pore 10, simultaneously tap hole 11 is closed, at this moment, fluid is by the hollow fluid passage and the honeycomb duct 5 of valve rod 3, the process fluid enters hole 6, fluid intercommunicating pore 10 enters piston cavity 12, acts on upper piston 4, promotes flap 1 downwards valve through hole 15 is closed.Valve is in closed condition.
Claims (2)
1, a kind of controllable self-generating valve, include valve body (14), valve gap (13), it is characterized in that the position corresponding to valve port (15) is provided with the piston set of being made up of upper piston (4) and lower piston (2) in the valve body (14), upper piston (4) and lower piston (2) are with coaxial the linking of valve rod (3), valve rod is established the hollow fluid passage in (3), hollow fluid passage upper end suit honeycomb duct (5), honeycomb duct (5) the other end break-through valve gap (13) is closed and Open valve through hole (15) or be communicated with piston cavity (12) through control valve (9) fluid passage and time push piston group and throttle down through hole (15) through control valve (9).
