Description
Technical field
The present invention relates to a kind of hydraulic control valve, mainly is to be used for hydraulic engineering, urban water supply and sewerage, sewage network, the two-way row of giving of sewage treatment, dual check, the controlled multifunctional flexible hydraulic control valve of water flow.
Background technique
Existing hydraulic control valve can be divided into diaphragm type and piston type by control mode, mainly be to realize valve opening, close or regulate and control the aperture size by means of flap or inner carrier driving mechanism, its actuator is a rigid material, the adjustment point can cause the control valve malfunction with the skew of operating conditions, control program is on the high side, and rate of fault increases, complex structure, the manufacturing process complexity, the manufacture cost height.
Existing rubber safety check is to utilize rubber natural elasticity sealing, is out of shape and is realized unidirectional defeated draining and non-return by water pressure and safety check abdominal cavity hydraulic pressure official post safety check, and its backpressure ability to bear is low, can not control the flow of water.
Summary of the invention
The purpose of this invention is to provide a kind of actuator is flexible material, adjusts point and covers a face width, but dual check, two-wayly carry out flow control, with safety check and the integrated multifunctional flexible hydraulic control valve of hydraulic control valve function.
The technical solution used in the present invention is: it is into (to go out) in the valve casing at the mouth of a river that the spool that flexible valve cylinder and aqueduct link into an integrated entity is installed on two ends, spool one end is fixed on the face of valve casing left end hole, the aqueduct of the other end axially moves in valve casing right-hand member hole with the opening and closing of flexible valve cylinder, valve casing right-hand member hole internal diameter is provided with seal ring, aqueduct is with the Adjustable device circle outward, one control waterway tube is communicated with the valve casing two ends respectively and advances (going out) mouth of a river and valve shell cavity, control waterway tube both sides are provided with little control valve and control the valve casing two ends respectively and advance (going out) mouth of a river and valve shell cavity conducting, the differential water pressures that forms between valve shell cavity and flexible valve tube inner chamber realizes the unlatching and the closure of flexible valve cylinder, is the swelling-waist shape that tends to narrowing toward each end broad in the middle behind the flexible valve cylinder complete opening.
After adopting above technological scheme, the beneficial effect that the present invention reaches is:
1, in the position control valve scope, it becomes the controllable bidirectional valve with one-way valve, and multi-purpose valve has improved the non-return pressure rating, the non-return stable action.
2, in the hydraulic control valve scope, it replaces the conventional rigid material with actuator's flexible material, reduces manufacture cost, improves reliability, the stationarity of control.
3, its simple in structure, reliable operation, easy to operate reduces hydraulic loss, and traditional safety check and control valve simple function are integrated in one, and can do gate valve, safety check, hydraulic control valve, pressure controlled valve use.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a spool plan view of the present invention.
Among Fig. 1, enter (going out) mouth of a river 1,9, valve casing left end hole face 2, valve casing 3, flexible valve cylinder 4, aqueduct 5, valve casing right-hand member hole face 6, seal ring 7, adjustable back-up ring 8, little control valve 10,12, valve shell cavity 11, control waterway tube 13.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, adopt the valve cylinder 4 of flexible material to be installed in the valve casing 3 with the spool that metal aqueduct 5 links into an integrated entity, one end of spool is fixed on the valve casing left end hole face 2, the aqueduct of the other end axially slides in valve casing right-hand member hole, right-hand member hole internal diameter is connected with seal ring 7 and close joining of aqueduct 5 external cylindrical surfaces, aqueduct is with adjustable back-up ring 8 outward, driving aqueduct when flexible valve cylinder is closed moves in valve, adjustable back-up ring is blocked in side, the right hole of valve casing 6 makes the spacing activity of spool, controls flexible valve cylinder and moves within the specific limits.The two ends of valve casing connect into (going out) mouth of a river 1,9 respectively, form valve shell cavity between valve casing left side and right side, and what control waterway tube 13 was communicated with the valve casing two ends advances (going out) mouth of a river and valve shell cavity 11, and control waterway tube both sides are equipped with little control valve 10,12.
Several working state of the present invention is:
1, establish little control valve 10 and be closed condition, control valve 12 is an opening state.
A, when water intake 1 water level is higher than water outlet 9 water levels, at this moment water intake 1 place's current enter flexible valve cylinder 4 inner chambers, the chamber pressure of flexible valve cylinder 4 is higher than valve shell cavity 11 pressure, flexible valve cylinder 4 dual-sides are strutted, water enters in the aqueduct 5 and from water outlet 9 and discharges, and aqueduct 5 moves a position to water outlet 9.Water intake 1 is big more for the pressure difference of water outlet 9, and aqueduct 5 amount of movements are just big more.
B, when water intake 1 water level is lower than water outlet 9 water levels, water outlet 9 is a water intake, water intake 1 is a water outlet.At this moment, water intake 9 place's current enter flexible valve cylinder 4 inner chambers through aqueduct 5, also enter valve shell cavity 11 through control waterway tube 13 simultaneously.But at this moment, because flowing of past water outlet 1 arranged at flexible valve cylinder 4 inner chambers, so the pressure of valve shell cavity 11 is greater than the chamber pressure of flexible valve cylinder 4, flexible valve cylinder 4 dual-sides just have the strength of inside closure, closed fully until flexible valve cylinder 4, aqueduct 5 moves to water outlet 1 direction, and pressure is big more, the aqueduct amount of movement is big more, and the adjustable back-up ring 8 restriction spools that side, valve casing right-hand member hole 6 is blocked on the aqueduct 5 move.Flow velocity is fast more, and valve shell cavity and flexible valve tube inner chamber pressure reduction are big more, and flexible valve cylinder closing force is also just big more.
2, establish little control valve 10 and be opening state, control valve 12 is a closed condition.
This state action is opposite with above-mentioned the 1st state action, but the minimizing of the amount of movement of aqueduct, the adjustable back-up ring on the aqueduct is inoperative.
3, the controllable bidirectional safety check of can doing that the 1st and the 2nd state closes uses.
4, the open degree of the little control valve 10,12 of adjustment can be adjusted the open degree and the closing speed of flexible valve cylinder 4.
