The novel high-pressure constant-flow adjusting valve has reasonable design and advanced technology, can realize constant-flow water injection, and is safe, reliable, convenient for maintenance and low in price.

Description

The high voltage and constant current modulating valve
Technical field
The utility model relates to a kind of flow regulator, particularly relates to the stable problem of water injection rate in the oil-field flooding engineering, is the improvement to existing flow regulator.
Background technique
The problem that prior art exists:
1, not high pressure resistant; 2, complex structure, volume is big, cost is high; 3, it is short easily to stop up, be not easy to maintenance, working life;
The model utility content:
The purpose of this utility model is the deficiency that exists at prior art, a kind of reasonable in design, advanced technology is provided, can realizes constant current water filling and safe and reliable, easy to maintenance, cheap novel product.
The technical solution of the utility model is: a kind of high voltage and constant current modulating valve, comprise a bottom flange that plays sealing process that is installed in valve body lower end, one is installed in the spring that regulating action is played in the piston lower end, a valve body that has water intake, water outlet and equalizing orifice, a piston that has annular groove and in annular groove, have the water inlet, one has the sleeve in chamber, water inlet, osculum and Flow-rate adjustment hole up and down, a flap that plays linear regulating action, a bonnet that plays sealing process, a handle that has locking effect; Bottom flange, bonnet be the valve seal one, flap the other end coupling sleeve and piston that an end is connected with handle.
The utility model is a kind of reasonable in design, advanced technology, can realizes constant current water filling and safe and reliable, easy to maintenance, cheap novel product.
Description of drawings
Fig. 1 is the utility model structure cut-away view;
Fig. 2 is tube-in-tube structure figure;
Fig. 3 is piston structure figure.
Concrete mode of execution
The utility model will be further described below in conjunction with accompanying drawing 1:
As shown in Figure 1, a kind of novel high voltage and constant current modulating valve, comprise a bottom flange 1 that plays sealing process that is installed in valve body lower end, one is installed in the spring 2 that regulating action is played in the piston lower end, a valve body 3 that has water intake 13, water outlet 6 and equalizing orifice 5, a piston 4 that has annular groove 14 and in annular groove, have the water inlet, one has the sleeve 7 in chamber, water inlet 12, osculum 8 and Flow-rate adjustment hole up and down, a flap 9 that plays linear regulating action, 10, one handles that have locking effect 11 of bonnet that play sealing process.
Working principle is: the needs according to flow system flow are adjusted to certain aperture setting flow by flap 9.The entrance point pressure action of medium is in the upper end of piston 4 at this moment, and the active force of outlet end medium passes through the elastic force acting in conjunction of equalizing orifice 5 and spring in the lower end of piston 4, and the amount of force at piston two ends equates, direction is opposite, and piston 4 is in state of equilibrium.When valve inlet and outlet pressure difference changes, change the annular groove 14 on the piston 4 and the relative position of the water inlet 12 on the sleeve 7 by the active force that acts on piston 4 two ends media, realize the purpose of constant flow.When the inlet and outlet pressure difference increases, flow velocity is accelerated, flow has increase trend, but, pressure reduction increases relatively because increasing, act on the active force of the medium of piston 4 upper ends, piston 4 moves down, the annular groove 14 on this moment piston 4 and water inlet 12 relative positions on the sleeve 7 change, the medium overflow section that they constitute is long-pending to be reduced, flow has the trend that reduces again, finally keep the flow of setting, reached the purpose of constant flow; When the inlet and outlet pressure difference reduces, flow velocity slows down, flow has the trend that reduces, but, pressure reduction reduces relatively because reducing, act on the active force of the medium of piston 4 upper ends, piston 4 moves up, the annular groove 14 on this moment piston 4 and water inlet 12 relative positions on the sleeve 7 change, the medium overflow section that they constitute is long-pending to be increased, flow has the trend of increase again, finally keep the flow of setting, reached the purpose of constant flow; Increase in the process of (or reducing) in valve inlet and outlet pressure difference, piston 4 (or making progress) downwards moves, and also with increasing (or reducing), the reaction force of spring increases (or reducing) to the decrement of spring, the active force at piston 4 two ends is tending towards equal, and piston 4 is in new state of equilibrium again.
Principal character of the present utility model:
1, simple in structure, appearance and size is little, in light weight, cost is low. Manual adjustments part and auto-compensation part all are installed in the same cavity, inlet opening, apopore, Flow-rate adjustment hole all are arranged on a part { on the sleeve 7}, simplified like this valve mechanism, reduced number of spare parts, dwindled valve overall dimensions, the light weight of valve of letter, saved the production cost of valve, be convenient to applying of product.
2, easy to maintenance. Control valve upstream and downstream valve closing can be unloaded bottom flange on the control valve when needing, take out the internals cleaning or change all very convenient.
3, the minimum discharge of constant-flow regulation valve can be zero. Because all with sealing ring, when flap 9 was closed, the flow of valve was zero, has overcome the difficult problem that most control valves can not end on sleeve and the piston.
4, have locking mechanism, can guarantee that the aperture of the valve that configures is constant.
