In this embodiment, the water sealing baffle 21 is pivotally connected to the cylindrical housing 200 at one end, and is movably mounted in the hollow portion 201 with the other end freely placed. Specifically, two sides of one end of the water sealing baffle 21 are respectively provided with a pivot shaft 210, and the side wall of the hollow part 201 is provided with a shaft hole matched with the pivot shaft 210 of the water sealing baffle 21, so that one end of the water sealing baffle 21 is fixed in the hollow part 201 in a pivot manner, and the other end of the water sealing baffle 21 is freely placed, so that the free end of the water sealing baffle 21 can be pushed open by water pressure, and water can flow out of the hollow part 201 of the water sealing base 20.
The switch assembly 3 comprises a switch valve 30, a connecting pipe 31, a movable buckle 32 and an elastic piece 33, wherein the water inlet end of the connecting pipe 31 is positioned at the front end of the water inlet 12 of the main valve cavity 10, the water outlet end of the connecting pipe 31 is communicated with the valve cavity 11 for two times, and the switch valve 30 is fixedly arranged on the connecting pipe 31 to control the water flow in the connecting pipe 31 to be opened and closed. In this embodiment, the side wall of the water inlet pipe 14 is provided with a joint pipe 141 which is communicated with the water inlet pipe, a three-way valve 142 is installed on the free end of the joint pipe 141, an outlet of the three-way valve is connected with an inlet of a three-way joint 143, and the other two outlets of the three-way joint 143 are respectively connected and communicated with the valve cavity 11 for two times through a connecting pipe 31.
Each valve cavity 11 is movably provided with a movable buckle 32, and each movable buckle 32 comprises a piston part 320 positioned in the secondary valve cavity 11, a resisting part 321 positioned in the main valve cavity 10 and a rod part 322 connecting the piston part 320 and the resisting part 321.

Each valve chamber 11 is also fixedly provided with an elastic member 33, which in this embodiment is a spring 33. The elastic member 33 acts on the piston portion 320 of the movable catch 32 in the secondary valve chamber 11, so that the elastic member 33 generates an elastic force on the movable catch 32 to push it toward the main valve chamber 10.
The hydraulic control valve provided in this embodiment is used as follows:
When the three-way valve (i.e. the switch valve 30) is adjusted to the closed state, referring to fig. 8, water flows into the secondary valve cavity 11 at the two axial ends of the main valve cavity 10 through the connecting pipes 31 at the two ends, the movable buckle 32 is pushed under the combined action of the water pressure in the secondary valve cavity 11 and the elastic force of the elastic piece 33 to press the water sealing baffle 21 in the main valve cavity 10 into the hollowed-out part 201 of the water sealing base 20, so that the cylindrical shell 200 of the water sealing base 20 is in the closed state, thereby blocking the water inlet 12 of the main valve cavity 10, water cannot flow into the main valve cavity 10 from the water inlet pipe 14, and the hydraulic control valve is in the closed state at this time.
When the three-way valve (i.e., the switch valve 30) is turned to the open state, referring to fig. 9, the water outlet end of the connector pipe 141 is in the closed state, and water cannot flow from the connecting pipe 31 into the secondary valve chamber 11 at the two axial ends of the main valve chamber 10, so that the water pressure in the water inlet pipe 14 overcomes the elastic force of the elastic member 33, and the water sealing baffle 21 is pushed away from the hollow portion 201 of the water sealing base 20, so that water can flow from the hollow portion 201 of the water sealing base 20 into the main valve chamber 10, and finally flows from the water outlet 13 into the water outlet pipe 15, and the water pressure control valve is in the open state.
The hydraulic control valve provided by the embodiment realizes sealing only by hydraulic force, has the advantages of small water head loss, large water flow, quick opening and closing reaction and the like, can effectively reduce the installation of other types of valves, and is beneficial to reducing the engineering cost.
In this embodiment, referring to fig. 4-6, the cylindrical housing 200 of the water seal base 20 is in a prismatic table shape, wherein the inner diameter of the prismatic table-shaped cylindrical housing 200 decreases sequentially from the opening end toward the closing end, each side of the prismatic table-shaped cylindrical housing 200 is provided with a hollow portion 201, and one end of the water seal baffle 21 near the opening end of the cylindrical housing 200 is pivoted with the cylindrical housing 200, and one end near the closing end of the cylindrical housing 200 is freely placed, so that the water seal baffle 21 can be pushed away by a smaller water pressure.
Preferably, the closed end of the cylindrical housing 200 is further provided with a cone 202 protruding toward the open end, and the outer diameter of the cone decreases sequentially from the closed end of the cylindrical housing 200 toward the open end, so that water entering the cylindrical housing 200 can better act on the free end of the water seal 21, and a smaller water pressure can push away the water seal 21.
It is further preferable that the width of the water seal 21 near the closed end of the tubular casing 200 is smaller than the width near the open end of the tubular casing 200, that is, the water seal 21 has a substantially trapezoidal shape, and the trapezoidal upper base plate faces the closed end of the tubular casing 200, so that the water seal 21 can be pushed open by a smaller water pressure.
In the present embodiment, referring to fig. 3, 5 and 10, the water blocking plate 21 includes a soft plate body 211 and a hard lining 212. Since the cylindrical housing 200 is made of a material with a relatively high hardness, such as metal or hard plastic, the plate 211 is generally made of a relatively soft material, such as rubber or silica gel, so that when the movable buckle 32 presses the plate 211, the plate 211 and the cylindrical housing 200 can have a better tightness with the cylindrical housing 200 due to the elastic deformation of the plate. However, since the soft plate 211 is easily deformed by the water pressure to cause water leakage, in this embodiment, the lining member 212 is generally made of a material with a relatively high hardness such as metal or hard plastic, and is embedded in the plate 211, so that the water sealing barrier 21 can have a high rigidity as a whole, preventing the deformation of the plate 211 and facilitating the rotation of the water sealing barrier 21 around the shaft. The lining member 212 includes an annular base 2120 configured to match the edge shape of the water seal baffle 21, a plurality of lining strips 2121 are disposed on the annular base 2120, insertion holes 2101 configured to match the lining strips 2121 are formed on the plate 211, and the lining strips 2121 are embedded into the insertion holes 2101 corresponding to the plate 211 for fixing, so that the water seal baffle 21 has good rigidity and strength as a whole, and a surface in sealing contact with the cylindrical housing 200 has a certain deformability to achieve a good sealing effect.
Referring to fig. 11, each of the valve chambers 11 is further provided with an exhaust hole 110 which is communicated with the external environment, and the position of the exhaust hole 110 communicated with the inner wall of the secondary valve chamber 11 is located on one side of the bottom surface of the piston portion 320 facing the main valve chamber 10, which is close to the main valve chamber, and is located outside the moving stroke of the piston portion 320, so as to prevent water leakage caused by the movement of the piston portion 320. The vent hole 110 prevents the piston part 320 from compressing air when moving, which results in the situation that the water sealing baffle 21 cannot be completely pressed, and simultaneously prevents the situation that the water sealing baffle 21 cannot push the movable buckle 32 open due to vacuum, which ensures the normal operation of the hydraulic control valve.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
