Abstract
The invention discloses a micro hydraulic control valve device, which belongs to measurement and control technology and particularly relates to a micro hydraulic control valve device. In the device, a valve body is connected with a valve cover; and the valve core passes through the valve body directly and is fixed on the valve body axially. The device is characterized in that: a groove is radially formed in the valve core; a hose 1, a hose 2, a hose 3, a hose 4 and a cross pipe adaptor are connected and are placed in the valve body; a hose 5 is also arranged in the valve body; the hose 5 and the hose 4 are connected with a sensor; a top wire is arranged in each of the hose 1, the hose 2, the hose 3 and the hose 4; the valve core has four gears; and with the rotation of the valve core among the four gears, the hoses are opened or closed respectively. The device has the advantages of realizing the opening and closing switching of various kinds of solution, preventing solution mixing, leakage and molecule inverse movement in a non-working state, meeting a nanoscale micro leakage requirement and applying to special connection environments with small space, multiple channels, low pressure, small flow, no leakage and no liquid mixing.
Description
Technical field
The present invention relates to belong to observation and control technology, be specifically related to a kind of miniature pilot operated valve device.
Background technique
At present, the hydraulic control valve internal structure all adopts valve body and the sealing of spool taper fit, and valve body and spool are directly radially passed in liquid paths hole, radially rotate to suitable angular orientation by spool, come shutoff port hole liquid line structure form.Can only limit 1 to 4 channel valve in engineering is used, spool frictional rotation moment is big.And, need take very large space, especially the machining accuracy height cooperates requirement tight, also occurs faults such as leakage and mixed liquid easily and lacks property.
Summary of the invention
It is little that technical problem to be solved by this invention provides a kind of volume, and valve core rotation moment is little, and multichannel does not have and leaks, and does not mix the miniature pilot operated valve device of liquid.
For solving the problems of the technologies described above, the technological scheme that the present invention takes is:
A kind of miniature pilot operated valve device, valve body and valve gap link together, spool directly passes valve body, and be axially fixed on the valve body, it is characterized in that the spool radial position is provided with groove, flexible pipe one, flexible pipe two, flexible pipe three, flexible pipe four are connected with cross pipe and place valve inner, flexible pipe five also places in the valve body, and flexible pipe five, flexible pipe four are connected with sensor again, also is provided with jackscrew in flexible pipe one, flexible pipe two, flexible pipe three, the flexible pipe four.
Described spool is provided with four gears, and when spool was in gear I position, jackscrew all flattened each flexible pipe one, flexible pipe two, flexible pipe three, flexible pipe four, and hydraulic control valve is in "off" state, and each hose passages does not all communicate; When spool went to gear II position, the flexible pipe one that is crushed, flexible pipe five restored to the original state at spool radial position groove, reach the state of " leading to ", and flexible pipe two, flexible pipe three valve element position places do not have groove, are in "off" state; When the spool gear was in the III position, flexible pipe two, flexible pipe five reached the state of " leading to ", and flexible pipe one, flexible pipe three are in "off" state; When the spool gear was in the IV position, flexible pipe three, flexible pipe five reached the state of " leading to ", and flexible pipe one, flexible pipe two are in "off" state.
Described spool is to be fixed on the valve body by plain washer, spring washer, nut.
The invention has the beneficial effects as follows the break-make switching function of realizing multiple solution, prevent that solution from mixing molecule backward motion under liquid, leakage and the off working state, satisfying leakage rate is nano level little seepage requirement.The special JA(junction ambient) that apparatus of the present invention are particularly useful for that the space is little, multichannel, low-pressure, small flow, nothing leak, do not mix liquid.
Description of drawings
Below in conjunction with the drawings and specific embodiments technological scheme of the present invention is further described in detail.
Fig. 1 is the structural representation of the miniature pilot operated valve device of the present invention.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of miniature pilot operated valve device, valve body 9 links together by connection set 8 with valve gap 11.Spool 10 directly passes valve body 9 and is axially fixed at one by plain washer 13, spring washer 14, nut 15.Flexible pipe 1, flexible pipe 24, flexible pipe 36, flexible pipe 42 are connected with cross pipe 3 and place valve body 9 inside, and flexible pipe 57 also places in the valve body 9.Flexible pipe 57, flexible pipe 42 are connected with sensor 5 again, and each flexible pipe 1, flexible pipe 24, flexible pipe 36, flexible pipe 57 also are equipped with jackscrew 12, form one six Channel Micro pilot operated valve device.When hydraulic control valve spool 10 was in gear I position, jackscrew 12 all flattened each flexible pipe 1, flexible pipe 24, flexible pipe 36, flexible pipe 57, and product is in "off" state, and each hose passages does not all communicate; When spool 10 went to gear II position, the flexible pipe 1 that is crushed, flexible pipe 57 restored to the original state at spool 10 radial position grooves, reach the state of " leading to ", and flexible pipe 24, flexible pipe 36 valve element position places do not have groove, are in "off" state; In like manner, when spool 10 gears were in the III position, flexible pipe 24, flexible pipe 57 reached the state of " leading to ", and flexible pipe 1, flexible pipe 36 are in "off" state; When spool 10 gears were in the IV position, flexible pipe 36, flexible pipe 57 reached the state of " leading to ", and flexible pipe 1, flexible pipe 24 are in "off" state.
It should be noted last that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
