Abstract
The utility model relates to a filter piston type hydraulic control valve which comprises a connecting plate, hexagonal screw nails, an O-shaped sealing ring, screw rods, hexagonal screw nuts, a cylinder cover and a cylinder body. The utility model is characterized in that a valve body connected with the cylinder body adopts a streamline Y-shaped wide valve body structure, and a hydraulic cylinder type piston transmission apparatus is arranged in the valve body. The utility model has the advantages of stable and reliable movement, little noise, large inflow rate, strong cavitation erosion resistance ability, little pressure loss, wear resistance and durability. When the utility model is operated, the buffering action is generated; the whole mechanism which has the functions of transmission, guiding and sealing can ensure that the opening and the closing of the valve are more accurate and reliable; the control valve and a filter are well combined together, the volume and the weight are greatly reduced, and the cost is saved.
Description
The utility model relates to a kind of control valve, particularly a kind of filtration piston-type underwater force control valve.
Valve says it is a kind of fluid control apparatus on performance, thereby its open and close of major control and aperture thereof reach switching and control the effect of its flow, pressure.On this basis, utilize hydraulic transmission principle to control the open and close and the aperture of flap, and reach requirement on the valve performance, and the fluid in the utilization management is as hydraulic transmission medium, and do not need independently hydraulic power unit, promptly save the investment of equipment, energy saving again also can reach the purpose of automatic control.But traditional valve products performance is single, and the kind of drive also is manually substantially, is difficult to realize multi-purpose valve and control automatically, can not satisfy the needs of modern pipe network.Existing diaphragm type hydraulic control valve can produce vibration because of pressure, flow rapid change, and noise is bigger, and film destroys easily, and inflow-rate of water turbine is few, and the pressure loss is big.
The purpose of this utility model is to provide the filtration piston-type underwater that a kind of stable action is reliable, noise is few, inflow-rate of water turbine is big, anti-cavitation erosion ability is strong force control valve.
The purpose of this utility model can reach by following measure: the utility model comprises connecting plate, hex screw, " O " RunddichtringO, screw rod, hexagon nut, cylinder cap, cylinder body, it is characterized in that: the valve body that links to each other with cylinder body adopts fusiform Y molded breadth valve body structure, is provided with the hydraulic cylinder type piston gear in the valve body.
The purpose of this utility model can also reach by following measure: near the ingress filter screen is housed also in valve body.The hydraulic cylinder type piston drive is put and is comprised " O " RunddichtringO, hexagon nut, spring washer, piston, socket head screw, spring, garden nut, stopping shim, rubber gasket, flap, lower valve base, leading truck, valve rod, piston is loaded on an end of valve rod, and be positioned at cylinder body and valve body jointing place, the other end of valve rod is equipped with leading truck, leading truck is positioned at the medium position of valve body, and spring is located between leading truck and the piston.
Fig. 1 is a structure sectional view of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
The utility model by connecting plate 1, hex screw 2, " O " RunddichtringO 3,4,9,12,14,16,23,25,30,, screw rod 5, hexagon nut 6,10, cylinder cap 7, cylinder body 8, spring washer 11, piston 13, socket head screw 15, spring 17, garden nut 18, stopping shim 19, rubber gasket 20, flap 21, lower valve base 22, leading truck 24, valve rod 26, filter screen 27, valve body 28, hex screw 29, valve gap 31 etc. form.
Valve body 28 adopts fusiform Y molded breadth valve body structure, so the pressure loss is little, than the control valve flow increase by 25% of existing general spherical valve body; And link to each other with cylinder body 8 by screw rod 5, hexagon nut 6, O RunddichtringO 12.Cylinder cap 7 is loaded on 8, and piston 13 is loaded on an end of valve rod 26 by hexagon nut 10, spring washer 11, O RunddichtringO 14, and is positioned at cylinder body 7 and valve body 28 jointing places; The other end of valve rod is equipped with flap 21, lower valve base 22 and leading truck 23 by garden nut 18, stopping shim 19, rubber seal 20.Lower valve base 22 and leading truck 23 are positioned at the trident intersection of Y valve body 28.Between flap 21 and piston 13, be provided with spring 17.In valve body 28, filter screen 27 is housed near the ingress.Design has three place positioning and guiding mechanisms in the valve body: i.e. piston 13, valve rod 26 and leading truck 24, in the time of guaranteeing valve opening and closing more accurately, reliable, overcome other valve one point location and cause the shortcoming that the location is unstable.Adopt a plurality of O RunddichtringOs of making by nitrile rubber, made sealingly secure reliable, also reached the performance requirement (temperature≤100 ℃, medium: water, oil) of valve.The vibration that the spring 17 that is provided with in the mechanism is produced in the time of preventing the rapid change of hydrodynamic pressure, flow, and when no flow automatic-closing valve, prevent the medium refluence.This moment, oil hydraulic cylinder had buffer function, reduced the influence of water slug pressure (being water hammer) to pipe network.
This control valve is under the constant situation of main valve, can be according to requirements different in the pipe network, enclose suitable control system and just can satisfy requirements different in the pipe network, as adjustable pressure-reducing valve, flow control valve, safety relief valve, stop valve, safety check, altitude valve etc.And can realize automatic control, automatically controlled, remote control, and its time and speed when opening and closing of control.Reach the effect of multi-purpose valve.
The utility model has following advantage compared to existing technology:
1, adopts Y molded breadth valve body structure and the hydraulic cylinder type piston drive of streamline line, so moving Do steadily reliably, the effect of buffering arranged during action, noise seldom, and inflow-rate of water turbine is big, anti-gas The erosion ability is strong, and the pressure loss is few, and is wear-resisting durable.
2, whole mechanism has transmission, guiding, sealing three big functions, and with valve body separately Independent, valve body is contained in the pipe network during use, also whole mechanism can be pulled down, thereby maintenance And it is very convenient to change spare and accessory parts, and can guarantee valve opening and closing the time more accurately and reliably.
3, control valve and filter are combined well, thus volume that significantly reduces and weight, and can on pipe network, lack a joint, simplify the structure of pipeline and saved cost.
