Description
Technical field
The present invention relates to a kind of flow control valve, particularly, the present invention relates to a kind ofly to be assembled in the water supply pipe, be used to control the flow control valve and the sprinkler head of shower-bath of the discharging amount of water.Described flow control valve is also referred to as " water-saving valve " or " water economizer ".
Background technique
In buildings such as tall building, hotel, office building, compare with the last water supply pipe that is positioned at place, building higher position, the height difference of the last water supply pipe that its position is lower is big, and its corresponding hydraulic pressure also increases.Therefore, for example, setting from the water of water supply pipe water tap emit and leading opening degree between relation, make described being set be beneficial to the water tap that is positioned at place, building higher position, then the hydraulic pressure on the water tap of building lower increases, even note closing at any time water tap, also situation about can waste water at ordinary times.Though even the water yield of each waste and little is accumulated over a long period, the then described water yield that wastes can be very big.Again, using the occasion of home-use shower etc., typically using such configuration structure: switching to the bathtub water and from the water of sprinkler head of shower-bath with switching valve.Yet, the bathtub water is required to discharge water with the speed of discharging water of maximum usually, yet, under the described speed that discharges water, when bathtub is discharged water the trickle state that switches to sprinkler head of shower-bath, then can make the shower injection flow rate excessive, cause unnecessary waste, in addition, because the ejection of trickle too rapidly, also can produce the bad odour that makes skin feel pain.
In order to improve above-mentioned condition, the someone has proposed several flow control valves.Figure 11 shows that the schematic representation that is installed on the flow control valve 101 on water tap 102 parts.As shown in the drawing, flow control valve is installed on the inside of water supply pipe.Figure 12 shows that the longitudinal sectional view (No. 3025904 communique of model utility) of an example of the structure of flow control valve 101 in the past again.Flow-rate adjustment before this is online, only at axial certain position place opening is set, and the adjusting system of its opening degree uses helical spring to carry out, so, can't carry out trace and regulate.Above-mentioned flow control valve system is used to improve above-mentioned thick opening degree and regulates and do.
With reference to Figure 12, flow control valve 101 comprises: the valve body 102 that constitutes the water flow passage major component, be opened in the first opening portion 102a of this dictyosome upper end, be opened in the outside thread bolt 103 that second opening portion on this body wall has the disc like top portion 103a that joins with above-mentioned valve body 2 inside sidewalls faces.Outside thread bolt 103a and screw 108 screwed joint of being located on the 102b of valve body bottom move its top 103a.The outer periphery diameter of this top 103a is bigger, the wall portion 107 that its diameter can the butt valve body, so, by moving axially that the rotation of outside thread bolt forms, can change the opening degree of second opening portion.
Water from first opening, one effluent to being provided with of second opening, one side, water is as shown in the drainage line 105, flow into valve body 102 from first opening side, current make after the one end is obstructed because of the top 103 of outside thread bolt, change its flow direction, emit from second opening portion, in the water supply pipe valve body of flowing through, as flowing to shown in 105.Formed sealing is not to seal completely between the interior mural painting of screw bolt top 103 and body wall outside, and water can permeate the sealing district, is stranded in the valve body bottom.Can think that also sometimes, water also can flow to water supply pipe inside by being arranged at screw on the valve body diapire 102b and the gap between the outside thread bolt.
With in the past only use traditional helical spring modulating valve by comparison, flow control valve in the past shown in Figure 12 in the adjusting of opening degree, can carry out trace and regulate.Yet, the Flow-rate adjustment that accomplish smoothness, trickle scale so that from the higher level of tall building to the structure at all levels of lower level, the adjusting of all can economizing on water fully is impossible.In the suburbs, city that is difficult to guarantee the water source, people require to develop a kind of flow control valve, and described flow control valve is convenient to water flow is carried out trickle Flow-rate adjustment, to deal with particularly unusual dry season of occurring in summer etc.
Again, flow control valve as shown in figure 12 in use opens and closes tap at every turn, and hydraulic pressure promptly acts on the top 103a of outside thread bolt repeatedly, makes the outside thread bolt that small vibration take place repeatedly.Again, in described outside thread bolt generation microvibration, water is by the space between outside thread bolt top and the body wall, among the gap that infiltration outside thread bolt and screw screw.Its result, the rotation that produces several angle in described microvibration accumulation, the former outside thread bolt tip position that is designed to suitable opening degree is offset, and can't carry out optimal flow rate control.The sealing function at outside thread bolt top is insufficient, directly causes the validity of Flow-rate adjustment to descend.
Again, in the COMM communication of switching with switching valve, carry out in bathtub, discharging water and the trickle of shower between switching the time, as the speed that discharges water at bathtub when maximum, when it was switched to the trickle of sprinkler head of shower-bath, this sprinkler head of shower-bath of ad hoc requirement has can make the trickle amount the suitably flow control valve of adjusting.
Therefore, first purpose of the present invention is: a kind of flow control valve is provided, and described flow control valve can carry out trickle flow control by the opening degree of setting smooth, trickle opening.
Another object of the present invention is: a kind of flow control valve is provided, and in a single day described flow control valve sets the opening degree adjusted position of opening, this adjusted position promptly be not easy to take place through the time change, described flow control valve is not easy to form incomplete sealing.
A further object of the present invention is: a kind of sprinkler head of shower-bath is provided, described sprinkler head of shower-bath is equipped with flow control valve, so that bathtub is being carried out discharging water of top speed, and discharge water when switching to the trickle of sprinkler head of shower-bath, can carry out the Flow-rate adjustment of suitable spraying water described.

Embodiment
Below, with reference to accompanying drawing, do an explanation with regard to example of the present invention.
Example 1
Figure 1 shows that the longitudinal sectional view of the flow control valve in the example 1.Described flow control valve mountain Austenitic Stainless Steel SUS304 constitutes.With reference to Fig. 1, this flow control valve 1 comprises valve body 2 that is provided with top entry oral area 2a and the outside thread bolt 3 that screws with the internal thread 8 that is arranged on this valve body 2 bottom 2b.
The sidewall of valve body 2 is provided with opening 4a, 4b.Here, importantly, near the first water outlet 4a of water inlet and, be not positioned at the axial same position of valve body than the second water outlet 4b of the more approaching bottom of first water outlet, but depart to some extent.In addition, in addition, be: near the opening area of the first water outlet 4a of water inlet opening area less than the second water outlet 4b as form preferably.Be more preferably, the first water outlet 4a and the second water outlet 4b repeat on above-mentioned axial position.The result of the first water outlet 4a and second repetition of water outlet 4b on above-mentioned axial position makes and can easily carry out setting pinpoint accuracy, trickle opening degree continuously not by stages.
In above-mentioned, the significance that a plurality of water outlets is just axially departed from configuration has been described, in Fig. 2, launch, exemplified the plan of establishment of other water outlet.Fig. 2 (a) is depicted as the figure that is provided with as the circular open of Fig. 1.On the position of full side face of halving, first row are set, secondary series respectively has two circular open.Two circular opens repeat on valve body is axial.Fig. 2 (b) is depicted as the figure that is divided into four-stage configuration circular open in the axial direction.On the circumferential position of the full side face of the quartering, the circular open of first row to the 4th row is set, and described circular open disposes with bolt shape respectively on each axial position.Fig. 2 (c) is depicted as groove shape opening, and on the position of full side face of halving, secondary series respectively has two slit openings.In Fig. 2 (d), on the circumferential position of the full side face of the quartering, on each axial position, become bolt shape ground respectively again,, on axial position repeated configuration first row to the groove shape opening of the 4th row.
So, make the multiple row opening, and the opening between the row is repeated on the valve body axial position, by this, can make stepless Flow-rate adjustment become possibility.Make the area of the area of first water outlet again, under the effect of above-mentioned two factors, can trickle, easily regulate flow less than second water outlet.
When Figure 3 shows that occasions such as flow control valve with example 1 is installed in the water supply pipe must sealing filling member example sectional view (among the figure, water outlet does not show).Fig. 3 (a) is for around the lug boss 25 that cone seal filling member 21 is installed on lip part 26 downsides, to cover the sectional view of lug boss.Again, Fig. 3 (b) is depicted as (a) is installed on sectional view under the state of water supply pipe 23.Lug boss 25 is positioned at the entry oral-lateral of first water outlet upper end.Numbering member title among the figure is as Fig. 1-3.Lug boss 25 and valve body 2 unitary mouldings.Be installed in around this lug boss, be the shape of opening towards the entry oral-lateral with the cone seal filling member 21 that covers lug boss.With water supply pipe when install in the outside, be fulcrum with the lug boss, described sealing filling member open part towards the body wall bending, be extruded to Yan body periphery and lip part 26, and press to lug boss 25 with brute force.Its result between lug boss and sealing filling member, and is surrounding lug boss, and is accepting to form strong sealing respectively between the inwall from the sealing filling member of the reaction force of lug boss and water supply pipe.Again, when in water supply pipe flow control valve being installed, the parts of numbering 23 are water supply pipe, in the time of on being installed on sprinkler head of shower-bath, and the water-guiding hole portion of numbering 23 expression sprinkler head of shower-bath.
By using above-mentioned cone seal filling member, can get rid of incomplete sealing, so, can therefore carry out the flow control of pinpoint accuracy.Again, when flow control valve of the present invention is installed on the water supply pipe 23, can easily carry out the centralized positioning of pinpoint accuracy, even use all the year round, can run-off the straight yet; Through using over a long time, flow set can be maintained certain level.
Example 2
Figure 4 shows that the sectional view of the flow control valve in the example 2.The maximum of the flow control valve in this example is characterised in that: the neck recess under the screw bolt top is installed an O type packing ring 11 outside.
Carry out flow set by following main points in the described flow control valve: the neck periphery under the 3a of screw bolt top is provided with depressed part outside, at this depressed part O type packing ring 11 is installed.This packing ring can be a synthetic rubber system, also can be the good silicone rubber system of Security and resistance to heat.Certainly, be more preferably the latter.Described O type packing ring outer periphery interface is close on the inner side surface of body wall, simultaneously, can make the revolution of outside thread bolt, and move axially along valve body.By this, can make described O type packing ring close attachment when the inner side surface of body wall slides, move.At the contact position downside of described O type packing ring, water is stopped that by described O type packing ring outer periphery in the second water outlet zone that is positioned at this position upper side range, water then can pass through this second water outlet zone.Therefore, the position of O type packing ring is the opening degree adjusted position of opening.
By the use of O type packing ring, water can not infiltrate into the valve body bottom from the gap of sealing.Thus, can not reduce the validity of Flow-rate adjustment, and the reduction of described validity is that direct cause is in incomplete sealing.The effect that prevents not exclusively sealing also produces effect to preventing the lax of outside thread bolt and rotating.Except preventing this incomplete seal action, described O type packing ring is because of the effect of elastic force and frictional force, with the outside thread bolt in certain position, so, even interrupted the variation takes place in hydraulic pressure, also be difficult for making the setting of the bolt position of outside thread bolt to change, can be with the bolt position long term maintenance of outer rib-loop bolt at correct desired location.
