Problems solved by technology

[0004] Problem 1 lies in: the spool of the electromagnetic proportional valve (5) is a floating structure, which cannot control the small air volume, so that the firepower cannot be reduced in summer, and it is too gas-intensive and hot to take a bath
[0005] Problem 2 lies in: the spool of the electromagnetic proportional valve (5) works in continuous suspension, which consumes a lot of power
[0006] Problem 3 lies in: large volume and high cost

Embodiment Construction

[0022] Depend on figure 2 It can be seen that the numerical control proportional valve includes: valve seat (1) solenoid valve (2) air valve core (3) air valve core pressure plate (4) return switch (5) gear (6) stepping motor (7) composition. The inlet pipe (1-1) of the valve seat (1) is inlaid with a fixed plate (1-2), and the air outlet (1-3) faces forward or upward; the solenoid valve (2) is located on the right side of the valve seat (1) , the air valve core (3) is located on the left side of the valve seat (1), and is fixed in the valve seat (1) by the air valve core plate (4), and the other end of the air valve core (3) is connected to the gear (6); The motor (7) is fixed on the air valve core pressure plate (4), the upper gear of the stepping motor (7) meshes with the gear (6), and the reply switch (5) is fixed on the air valve core pressure plate (4); When the upper gear of the stepping motor (7) pushes the gear (6) to press the return switch (5) to close, at this ti...

Abstract

A numerical control proportional valve is composed of an aluminium valve seat, an electromagnetic valve, an air valve element, an air valve element pressing plate, an echo switch, a gear and a stepping motor. When the echo switch is switched off, the air valve element driven by the gear is just placed at the closed position or at the position where a small amount of air flow is provided for a fire grate at the moment. When the opening degree of the air valve element reaches 20% or 30%, only the number of corresponding stepping pulses is provided for the motor.

Description

technical field [0001] The invention relates to a valve, especially a proportional valve for a constant temperature gas water heater. Background technique [0002] The existing electromagnetic proportional valve temperature adjustment method is: different working currents are passed into the coil, and the armature drives the gas valve core to produce different currents. [0003] same opening. [0004] Problem 1 is in: the spool of electromagnetic proportional valve (5) is a floating structure, which cannot control the tiny air volume, which causes the firepower to fail to drop in summer, and it is too gas-intensive and scalding to take a bath. [0005] Problem 2 lies in: the spool of the electromagnetic proportional valve (5) works in a continuous suspension mode, which consumes a lot of power. [0006] Problem 3 lies in: large volume and high cost. Contents of the invention [0007] The object of the present invention is to provide a numerically controlled proportional...
