Description
Technical field
The present invention relates to a kind of hydraulic pressure switch, specifically for the device of detection and control flow.
Background technique
Suction booster feedwater supercharging all will be being used toward multiple occasions such as eminence water deliverys.Hydraulic pressure switch is exactly the device of the flow of water in detection and control pipeline.
At present, the single-pipeline that is designed to of hydraulic pressure switch common on market supplies water, and its structure is comparatively accurate, function admirable, but once pipeline blocking occurs or damages, whole hydraulic pressure switch will be scrapped, and user cost is higher.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thus a kind of hydraulic pressure switch is provided, adopt dual circuit to supply water, reduce rate of fault and maintenance rate.
According to technological scheme provided by the invention, hydraulic pressure switch comprises sensitive switch, compression fittings, spool and main valve body, main valve body side is threaded compression fittings, spool is provided with in compression fittings, compression fittings front is provided with sensitive switch, spool left end can stretch out compression fittings and contact sensitive switch, it is characterized in that: in main valve body, be provided with fluid passage, main valve body side is provided with the first water intake and the second water intake, opposite side is provided with the first water outlet and the second water outlet, first water intake, second water intake, first water outlet is communicated with fluid passage respectively with the second water outlet, be provided with spring between spool left end and compression fittings, spool right-hand member is pressed on main valve body by spring, blocks the port of fluid passage.
Further, outer seal ring is provided with between compression fittings and main valve body.
Further, inner seal ring is provided with between compression fittings and spool.
Compared with the prior art the present invention has the following advantages:
The present invention adopts dual circuit, reduces rate of fault and maintenance rate, improves working life; Reduce user cost; Compact structure, small and exquisite; Highly sensitive, stable performance, there is good impact resistance; Using scope is extensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-sensitive switch, 2-compression fittings, 3-spring, 4-outer seal ring, 5-inner seal ring, 6-spool, 7-first water intake, 8-main valve body, 9-second water intake, 10-first water outlet, 11-second water outlet, 12-fluid passage.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises sensitive switch 1, compression fittings 2, spool 6 and main valve body 8, be provided with fluid passage 12 in main valve body 8, main valve body 8 side is provided with the first water intake 7 and the second water intake 9, and opposite side is provided with the first water outlet 10 and the second water outlet 11.First water intake 7, second water intake 9, first water outlet 10 is communicated with fluid passage 12 respectively with the second water outlet 11.First water outlet 10 and the second water outlet 11 place are used for connected electromagnetic valve.
Main valve body 8 side is threaded compression fittings 2, and be provided with spool 6 in compression fittings 2, be provided with spring 3 between spool 6 left end and compression fittings 2, spool 6 right-hand member is pressed on main valve body 8 by spring 3, blocks the port of fluid passage 12.
Compression fittings 2 front is provided with sensitive switch 1, and spool 6 left end can stretch out compression fittings 2 and contact sensitive switch 1.
Be provided with outer seal ring 4 between described compression fittings 2 and main valve body 8, strengthen the seal degree between compression fittings 2 and main valve body 8 by outer seal ring 4.
Be provided with inner seal ring 5 between described compression fittings 2 and spool 6, strengthen the seal degree between compression fittings 2 and spool 6 by inner seal ring 5.
Working principle of the present invention is: during work, and fluid flows to main valve body 8 by the first water intake 7 and the second water intake 9, flows out main valve body 8 by the first water outlet 10 and the second water outlet 11.Fluid overcomes spring 3 pressure and promotes spool 6 in fluid passage 12.If flow is excessive, then fluid forces spool 6 stretches out compression fittings 2 and contacts sensitive switch 1, and sensitive switch 1 controls the solenoid valve that the first water intake 7 is connected with the second water intake 9 place, thus controls the size of flow.The present invention adopts dual circuit, and when one of them pipeline of hydraulic pressure switch blocking occurs or damages, another one pipeline still can ensure the normal work of hydraulic pressure switch, can extend the working life of hydraulic pressure switch, effectively reduce costs.Overall structure of the present invention adopts metallic copper integrated member, high-precision spool and solenoid valve, has highly sensitive, stable performance, good impact resistance.The full soldering and sealing of metallic copper connects, compact structure, compact, has the media compatibility of good protection against the tide, anti-corrosion capability and excellence.The present invention can change solenoid valve according to measured liquid difference, thus is widely used in industry equipment, water conservancy, hydraulic pressure etc.
