Description
Technical field
The utility model relates to and a kind ofly acts on the valve that activates on the barrier film by fluid, particularly a kind of can be manually opened and can be automatically or manually regulate the barrier film water valve of flow.
Background technique
Existing barrier film water valve can be with reference to shown in Figure 3, comprise valve body 1 ', valve gap 2 ' and barrier film 3 ', valve body 1 ' is provided with intake pipe 11 ', outlet pipe 12 ' and control mouth 13 ', be provided with inlet 14 ' between outlet pipe 12 ' and the intake pipe 11 ', barrier film 3 ' is arranged between valve gap 2 ' and the control mouth 13 ', and be in inlet 14 ' top, form a water pressure balance cavity 20 ' between barrier film 3 ' and the valve gap 2 ', be provided with spring 8 ' between barrier film 3 ' and the valve gap 2 ', barrier film 3 ' bottom is provided with the projection 30 ' that blocks water, this projection 30 ' that blocks water can block on inlet 14 ', and the path between outlet pipe 12 ' and the intake pipe 11 ' is blocked; Outlet pipe 12 ' madial wall is provided with down intercommunicating pore 51 ', valve gap 2 ' is provided with a solenoid valve mounting groove 4 ', solenoid valve mounting groove 4 ' bottom is provided with a last intercommunicating pore 52 ' that communicates with the following intercommunicating pore 51 ' of outlet pipe 12 ' madial wall, solenoid valve mounting groove 4 ' sidewall also is provided with the through hole 53 ' that communicates with water pressure balance cavity 20 ', barrier film 3 ' is provided with an equalizing orifice 6 ', this equalizing orifice 6 ' communicates water pressure balance cavity 20 ' and intake pipe 11 ', in the solenoid valve mounting groove 4 ' solenoid valve 7 ' is installed, the valve core 70 ' of solenoid valve 7 ' is positioned at intercommunicating pore 52 ' top.
When the solenoid valve 7 ' of above-mentioned barrier film water valve is switched on, its spool 70 ' is upwards inhaled, last intercommunicating pore 52 ' is on state, and water pressure balance cavity 20 ' and outlet pipe 12 ' are connected, and its hydraulic pressure equals the hydraulic pressure of outlet pipe 12 ', and less than the hydraulic pressure of intake pipe 11 ', therefore, barrier film 3 ' is upwards pushed up, and the projection 30 ' that blocks water leaves inlet 14 ', inlet 14 ' conducting, intake pipe 11 ' and outlet pipe 12 ' are communicated with; During solenoid valve 7 ' outage, its spool 70 ' stops up downwards goes up intercommunicating pore 52 ', because the hydraulic pressure of intake pipe 11 ' is higher than the hydraulic pressure in the water pressure balance cavity 20 ', water slowly enters in the water pressure balance cavity 20 ' from equalizing orifice 6 ', equate up to barrier film 3 ' two side hydraulic pressures, barrier film 3 ' is pressed on the inlet 14 ' under spring 8 ' elastic force effect, is blocked between intake pipe 11 ' and the outlet pipe 12 '.In addition, the barrier film water valve that yet has does not have spring 8 ', and its course of action relies on barrier film 3 ' elasticity own to finish fully.
As mentioned above, the distance that barrier film 3 ' quilt made progress jack-up when the flow size of this barrier film water valve depended primarily on its conducting, and this distance depends primarily on the size of hydraulic pressure and the elasticity of barrier film, hydraulic pressure is big or barrier film elasticity is bigger, then its flow is bigger, otherwise then flow is less, and as seen, its flow can not be regulated as required; In addition, if solenoid valve is out of order or has a power failure, solenoid valve can't be worked, and then this water valve is ineffective.

Embodiment
Embodiment of the present utility model, see figures.1.and.2, comprise valve body 1, valve gap 2 and barrier film 3, valve body 1 is provided with intake pipe 11, outlet pipe 12, be provided with opening inlet 10 up between intake pipe 11 and the outlet pipe 12, part in the inlet 10 links to each other with outlet pipe 12, inlet 10 outer parts link to each other with intake pipe 11, barrier film 3 is arranged between valve gap 2 and the valve body 1, barrier film 3 middle parts are provided with the plug 31 that can block in inlet 10, form a water pressure balance cavity 20 between barrier film 3 and the valve gap 2, the one side top of valve gap 2 is provided with a solenoid valve mounting groove 21, be provided with intercommunicating pore 210 between this solenoid valve mounting groove 21 and the outlet pipe 12, solenoid valve mounting groove 21 also is provided with the water port 211 that communicates with water pressure balance cavity 20, barrier film 3 is provided with the hydraulic balance hole 32 that water pressure balance cavity 20 and intake pipe 11 are connected, the size in this hydraulic balance hole 32 is minimum, solenoid valve 4 is installed in the solenoid valve mounting groove 21, and the valve core 41 of solenoid valve 4 is above the intercommunicating pore 210 between solenoid valve mounting groove 21 and the outlet pipe 12.
When solenoid valve 4 no electric circuits, its spool 41 relies on intercommunicating pore 210 tops, be not communicated with between water pressure balance cavity 20 and the outlet pipe 12, water in the intake pipe 11 enters water pressure balance cavity 20 by hydraulic balance hole 32 at this moment, hydraulic pressure in the water pressure balance cavity 20 equates with hydraulic pressure in the intake pipe, sprue 81 is subjected to hydraulic action, upwards rely on the ladder of the spacing body of rod 7 cavity bottoms, thereby water pressure balance cavity 20 is not communicated with outlet pipe, hydraulic action in the water pressure balance cavity 20 is on barrier film 3, plug 31 is blocked on inlet 10, thus obstructed between intake pipe 11 and the outlet pipe 12, and this barrier film water valve is in closed condition.
If solenoid valve 4 energisings, its spool 41 moves up, intercommunicating pore 210 and water port 211 are linked to be path, and water pressure balance cavity 20 and outlet pipe 12 are connected, and the size in hydraulic balance hole 32 is minimum, thereby the hydraulic pressure in the water pressure balance cavity 20 reduces, hydraulic pressure in the intake pipe 11 is bigger, and under this hydraulic action, barrier film 3 is by the jack-up that makes progress, be communicated with by inlet 10 between intake pipe 11 and the outlet pipe 12, this barrier film water valve is in opening state.If solenoid valve 4 outages, path between water pressure balance cavity 20 and the outlet pipe 12 is blocked, hydraulic pressure in the water pressure balance cavity 20 slowly are increased to identical with hydraulic pressure in the intake pipe 11, and barrier film 3 blocks on inlet 10 under the effect of himself weight and pressure spring 9, and this barrier film water valve promptly cuts out.
As from the foregoing, the amplitude that barrier film 3 moves upward is big more, inlet 10 opening degrees are just big more, the flow of water is also just big more, therefore can it be moved up and down by rotation adjusting screw 5, move up and down thereby drive the spacing body of rod 7, can reach the upwards amplitude peak of action of restriction barrier film 3, thereby the flow of adjustable water saving.
If solenoid valve 4 damages or has a power failure, then the path through solenoid valve mounting groove 21 is blocked between water pressure balance cavity 20 and the outlet pipe 12, can't open this barrier film water valve by solenoid valve 4.Downwards press cylinder 8 by the perforation in the adjusting screw 5 50 this moment, sprue 81 moves downward thereupon, water can flow through space, spilled water hole 71, [212 and intercommunicating pore 210 between cylinder 8 Lower Halves and the spacing body of rod 7 cavity Lower Half inwalls, enter outlet pipe 12, then water pressure balance cavity 20 is connected with outlet pipe 12; On the contrary, behind the relieving cylinder 8, under the effect of pressure spring 9, sprue 81 resets, and this path is blocked.This shows,, also can realize the switching of this barrier film water valve by making cylinder 8 actions.
