Valve seat: link to each other with oil hydraulic cylinder by adpting flange, have three port T, P
1And P
2,
Valve rod: its upper end is connected with coupling and piston rod in turn, extends to oil hydraulic cylinder through piston rod, and the lower end extends to valve seat, and valve rod can move up and down by the relative valve seat of drive of coupling and piston rod;
Upper valve body: be positioned at valve seat top, separate, when the lower end surface of upper valve body contacts with the valve rod that moves upward, make the T mouth close P with valve seat
1Mouth and P
2Mouth communicates;
Following valve body: be positioned at the valve seat bottom, separate, when the upper-end surface of valve body contacts with the valve rod that moves downward instantly, make P with valve seat
1Mouth is closed T mouth and P
2Mouth communicates.
Wherein, the A mouth of described oil hydraulic cylinder is communicated with high pressure oil, and the B mouth is communicated with hydraulic oil container; Perhaps, the A mouth is communicated with hydraulic oil container, and the B mouth is communicated with high pressure oil, is used for providing pressure to oil hydraulic cylinder, makes coupling and piston rod drive valve rod and moves up and down.
Wherein, be provided with oil sealing device between described oil hydraulic cylinder and the joint, piston rod top, gap between the place is used to be tightly connected.
Wherein, be provided with water sealing device between described valve seat and the stem lower portion branch joint, gap between the place is used to be tightly connected.
The advantage of the utility model hydraulic control water valve device is: what hydraulic control two-bit triplet high pressure water valve adopted is that the high low pressure chamber separates the project organization that design, oily power source and water route separate, this product stable work in work, the commutation reliable in action, the life-span of product is long, applied widely, the liquid that comprises industrial water all can use, and it is simple and easy reliable to commutate.Adopt board-like good sealing effect, not easy to wear, positioning accuracy request is not high.Turbidity test to liquid are less demanding, are easier to use and promote.Working pressure can reach 31.5MPa, and flow can reach more than the 120L/min, also can proper functioning under the operating conditions condition of severe, and overcome traditional sliding valve style hydraulicdirectional control valve and be not suitable for the situation that medium is a water, require high for the cleaning liquid degree.
Description of drawings
Fig. 1 is that schematic representation cuts open in the office of the utility model hydraulic control water valve device.
Among the figure: 1: oil hydraulic cylinder; 2: adpting flange; 3: water sealing device; 4: valve seat; 5: following valve body; 6: upper valve body; 7: valve rod; 8: coupling; 9: piston rod; 10: oil sealing device.
Embodiment
Be described further with regard to a kind of hydraulic control water valve device described in the utility model below in conjunction with the drawings and specific embodiments.
The hydraulic control two-bit triplet high pressure water valve that the utility model is related is made up of the board-like selector valve group of a small-sized hydraulic power unit control.Fig. 1 is that schematic representation cuts open in the office of hydraulic control two-bit triplet high pressure water control valve unit, mainly represents each several part structure and position relation.Power unit comprises oil hydraulic cylinder 1, and two mouth A mouths and B mouth are wherein arranged; Connect oil hydraulic cylinder 1 and valve seat 4 with adpting flange 2; 3 port T, P1 and P2 are arranged on the valve seat 4, all communicate.
In valve rod 7 moves up and down process, impact mutually with upper valve body 6 and following valve body 5, fragile valve body, repair and replacement for convenience, upper valve body 6 and following valve body 5 devices separate design with valve seat 4.
Adopt oil sealing device 10 between oil hydraulic cylinder 1 and the joint, piston rod 9 top, adopt water sealing device 3 between valve seat 4 and the joint, valve rod 7 bottom, gap between the place is used for respectively being tightly connected.
When port of power unit was communicated with high pressure oil, high pressure oil promoted board-like valve rod 7 and moves to a position, and hydraulic oil flows to fuel tank from another port.Board-like valve rod 7 compresses a port with valve body 4, this liquid road port closure that flows, and liquid two ports outside two flow to outflow.When power unit another one port communicated with high pressure oil, board-like valve rod 7 can move to the another one position, with valve body 4 the another one port is compressed, and this liquid road port closure that flows, liquid flows to outflow from all the other two ports.
