Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1, Fig. 2 are the sectional elevations of the utility model hydraulic control valve.
Fig. 3 is the partial enlarged drawing of the utility model hydraulic control valve.
(1) is main valve in the drawings, and (2) are pilot valves, and (3) are one-way valves, (4) be water intake, (5) are hydraulic chambers, and (6) are boss, (7) be cartridge cover, (8) are spools, and (9) are water annuluss, (10) be breach, (11) are valve bodies, and (12) are the mouths of a river, (13) be water outlet, (14) are valve pockets, and (15) are the pilot valve mounting holes, (16) be spool, (17) (18) are the water holes, and (19) are water channels, (20) be gland, (21) be the gland card, (22) are the pilot valve core holes, and (23) are the one-way valve spools, (24) be one-way valve spool hole, (25) be one-way valve spool hole, (26 (27) (28) (30) (32) is the pilot valve core cylindrical body, and (29) are the pilot valve core semicylinders, (31) be peach shape chute, (33) be the zigzag card, (34) are springs, and (35) are the pilot valve valve cylinders.
The profile of valve pocket (14) can be a different shape, as: prism, cylindrical body etc.Hydraulic control valve is to be installed in the supply channel, and water intake (4) joins with running water pipe or penstock, and water outlet (13) joins with outlet pipe, the Placement steel pipe adopts and is threaded, plastic tube adopts support to insert the connection of formula drive fit, and the two sealing is reliable, and water can not overflow.After installing, tap water enters water hole (17) by water intake (4), water annulus (27), (9), breach (10), the top of the mouth of a river (12).The pilot valve core cylindrical body is a Spielpassung between outer wall of (26) (28) and pilot valve core hole (22) inwall, good airproof performance, and water can not overflow.Hydraulic chamber (5), water channel (19), water hole (18), pilot valve core hole power is zero.Because spool (8) round platform surface is subjected to the effect of water pressure, spool moves on (8), and tap water is (12) through the mouth of a river, and one-way valve spool (24) is closed by water pressure automatically, flows into water outlet (13), i.e. valve water flowing.
When valve stops water flowing, very little thrust F is given at pilot valve core (16) top, pressure spring (34) moves in pilot valve core hole (22), the foxy suitable up peach shape chute of font card (33) goes upward to the summit of chute simultaneously, enter locating slot, deduct pilot valve core (16) thrust F, pilot valve core (16) location.This moment water hole (17) (18), water annulus (27), water channel (19) hydraulic chamber (5) communicates, tap water enters hydraulic chamber (5), produces water pressure.Because spool (8) is sectional area poor up and down, (S
On＞S
Down, i.e. F
On＞F
Down), spool (8) moves down, and for line contacts, closed performance is good between round platform position and the mouth of a river (12) suitable for reading, and water can not overflow.Between spool (8) outer wall and hydraulic chamber (5) inwall is Spielpassung, and encapsulation is good, and water can not overflow into mutually.
When the valve water flowing, very little thrust F is given at pilot valve core (16) top, pilot valve core (16) moves, font card (33) head skids off locating slot, deducts the thrust F of pilot valve core (16), and pilot valve core (16) is under the effect of spring (34), outside pilot valve core hole (22), move, the foxy suitable descending peach shape chute of font card (33) comes downwards to the nadir of groove simultaneously, enters locating slot, i.e. pilot valve core (16) location.This moment water hole (18), water channel (19), hydraulic chamber (5), one-way valve (3), the mouth of a river (12), water outlet (13) communicates, hydraulic chamber (5) press water flows out, pressure is zero.Spool (8) round platform surface is because the effect of water pressure, and spool moves on (8), and tap water rises, and mouthful (12) to flow into water outlets (13) be the valve water flowing, goes round and begins again, and realized the purpose of stopping supplying water.
The utility model compared with prior art has lower following good effect:
1, adopt hydraulic transmission technology, reduced the wearing and tearing of parts, increased substantially sealing, The pilot valve that the utility model hydraulic control valve adopts, check valve, the structure of main valve is organically tied it Be combined, interact, reached the purpose of stopping supplying water, effectively stopped run, drip, leak The generation of water phenomenon.
2, according to the character of other fluids, medium, can select different materials to produce satisfactory liquid Pressure control valve.
3, this valve arrangement is simple, flexibly, stable performance, manufacture craft is simple, and is cheap, installs Convenient, the characteristics such as using water wisely.
