Front and back pressure difference is adjusted for connecting.
Preferably, being equipped with reset spring on the body of rod that the bottom spool is connected, one end of the body of rod and bottom spool connect
It connects, the lower end of the body of rod is connect with pressure control diaphragm, and pressure controls diaphragm and utilizes front and back pressure difference, closes bottom spool, Jin Erping
Weigh flow.
The utility model has the beneficial effects that having both balance and control function, it has not only been able to achieve the automatic control of flow system flow, but also
It can be remained unchanged when system pressure changes using pressure difference autobalance downstream flow, improve energy transmission efficiency,
The operating power consumption of water pump is reduced, and valve is small in size, simple installation effectively avoids damage to, and reduces debugging, installation and maintenance dimension
Protect cost.
Detailed description of the invention
It is described in detail the utility model with reference to the accompanying drawings and detailed description；
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Referring to Fig.1, present embodiment uses a kind of following technical scheme: dynamic differential pressure balanced type electric control valve,
Including valve rod 1, bonnet, 2, pressure tap 3, valve body 4, upper valve core 5-1, bottom spool 5-2, upper balancing sleeve 6-1, lower balancing sleeve
6-2, pressure control diaphragm 7, bottom flange 8, reset spring 10, catheter pressure 11, and the upper end of valve body 4 is equipped with bonnet, 2, valve body
4 lower end is equipped with bottom flange 8, and 4 two sides of valve body are provided with pressure tap 3, valve rod 1 is equipped on bonnet, 2, valve body 4 is by top
Flow control area and lower part flow equilibrium district's groups at being provided with valve port 9, flow between flow control area and flow equilibrium area
Upper valve core 5-1, upper balancing sleeve 6-1 are installed in control zone, bottom spool 5-2, lower balancing sleeve are installed in flow equilibrium area
6-2, reset spring 10, one end that valve rod 1 is located in valve body 4 are fixedly connected with upper valve core 5-1, and upper valve core 5-1 is socketed on flat
It weighs in sleeve 6-1, bottom spool 5-2 is socketed in lower balancing sleeve 6-2, and valve body 4 is built-in with catheter pressure 11, valve body 4 and lower valve
Pressure control diaphragm 7 is installed in the inner space that lid 8 connects.
It is worth noting that, be equipped with reset spring 10 on the bottom spool 5-2 connected body of rod, one end of the body of rod with
The lower end of bottom spool 5-2 connection, the body of rod is connect with pressure control diaphragm 7, and pressure controls diaphragm 7 and utilizes front and back pressure difference, makes lower valve
Core 5-2 is closed, and then balanced flow.
The working principle of the present embodiment is as follows: (1) valve rod 1 is connect with Electric Actuator, when system operation, is driven
Spool 5-1 moves up and down, and then controls flow and increase or decrease；
(2) when system pressure remains unchanged, bottom spool 5-2 keeps full-gear, system under the drive of reset spring 10
Required uninterrupted is kept controlling by electronic spool position；
(3) when system pressure becomes larger, pressure difference changes therewith before and after valve, at this point, upstream pressure passes through built-in pressure
Pressure load to pressure is controlled diaphragm 7 by power conduit 11, and pressure controls diaphragm 7 and utilizes front and back pressure difference, compression reseting spring 10, band
Dynamic bottom spool 5-2 is moved to closing direction, to play the role of balanced flow.
Present embodiment is a kind of in heating system, having 100% valve anthority and automatic flow limitation function
