Abstract
The utility model relates to a control valve which changes the spring pressure to achieve the automatic control of the water pressure. The control valve belongs to a pressure adjustment field. Besides an outer casing (1), a water inlet chamber (8) and a water outlet chamber (7), the utility model is characterized in that the upper end of the outer casing (1) is connected with an adjusting screw (2), the adjusting screw (2) is connected with a pressure plate (4) through an adjusting spring (3), the pressure plate (4) goes in turn through a sealing rubber (5) and drawbars (6) and is connected with stop valve (9), the stop valve (9) is actively connected with the water inlet chamber (8)., the stop valve repeatedly opens and closes to achieve the automatic adjustment of the water pressure, and the adjusting screw (2) is revolved in and revolved out according to the need of the adjustment pressure to change the pressure of the adjusting spring (3), furthermore, to change the water pressure.
Description
Technical field:
The utility model belongs to pressure and regulates the field, is that a kind of pressure that changes spring that utilizes is realized the hydraulic pressure control valve of control automatically.
Background technique:
Now, in order to guarantee the regular supply of water, the pressure of water is generally all very high, thereby causes a series of problem: can be enough to bear pressure just some bearing hot water devices must be thickeied, cause cost too high.Hydraulic pressure is big more, and water flows fast more, causes the waste of water resources in some cases.
Summary of the invention:
The utility model purpose just provides a kind of water pressure energy and regulates automatically, hydraulic control valve easy to use.
The purpose of this utility model is achieved in that a kind of hydraulic control valve, form by shell (1), intake chamber (8), water-supplying chamber (7), it is characterized in that described shell (1) upper end connects adjusting screw (2), adjusting screw (2) connects pressing plate (4) by spring (3), be connected with cut-off valve (9) with pull bar (6) by caulking gum (5) successively under the pressing plate (4), cut-off valve (9) flexibly connects with intake chamber (8), by cut-off valve (9) repeated open, close, realize the automatic adjusting of hydraulic pressure.
Optimum implementation of the utility model is: Regulation spring (3) is connected with cut-off valve by pull bar (6), the pressure of Regulation spring, spring rises under the effect of hydraulic pressure, descending, drive cut-off valve (9) repeated open, close, realize the automatic control of hydraulic pressure.
The utility model compared with prior art has following advantage:
Cut-off valve (9) is owing to adopt hard system rubber, and the shell valve seat adopts hard close fit mode, long service life, safety coefficient height.
Description of drawings:
Figure is the utility model concrete structure schematic representation:
1. shell 2. adjusting screw 3. Regulation springs 4. pressing plates 5. seal rubbers
Embodiment:
Shell (1) adopts aluminium die casting to form, and cut-off valve (9) adopts hard system rubber.During use, water enters water-supplying chamber (7) by intake chamber (8), pressure in the water-supplying chamber (7) rises gradually, rise in the time of to overcome spring pressure, caulking gum (5), pressing plate (4), Regulation spring (3) rises under hydraulic action, thereby cause the rising of pull bar (6), drive cut-off valve (9) and be closed gradually, during water, the pressure of water-supplying chamber reduces gradually, caulking gum (5) is descending under the effect of Regulation spring (3), thereby causes the descending of pull bar (6), and cut-off valve (9) is opened, water enters water-supplying chamber (7) by intake chamber (8), so repeatedly, cut-off valve constantly cuts out, open, make water-supplying chamber (7) keep a fixing hydraulic pressure.Regulate hydraulic pressure, only need to screw in as required (back-out) adjusting screw (2), change the pressure of Regulation spring (3), thereby change the pressure of water.
Claims (2)
1. hydraulic control valve, form by shell (1), intake chamber (8), water-supplying chamber (7), it is characterized in that described shell (1) upper end connects adjusting screw (2), adjusting screw (2) connects pressing plate (4) by spring (3), be connected with cut-off valve (9) with pull bar (6) by caulking gum (5) successively under the pressing plate (4), cut-off valve (9) flexibly connects with intake chamber (8).
2. hydraulic control valve according to claim 1 is characterized in that described cut-off valve (9) is to connect special block rubber by a metallic rod away from pull bar (6) one ends to make.
