Embodiment Construction

[0022] The technical solution of the manual-automatic integrated piezoelectric valve of the present invention will be further described in detail below in conjunction with the embodiments shown in the accompanying drawings.

[0023] The invention discloses a manual-automatic integrated piezoelectric valve, which comprises a flexible membrane main valve core 13, which is arranged between the main valve inlet 1 and the main valve outlet 4, and is used to control the main valve The conduction and shutoff between the inlet 1 and the main valve outlet 4, the peripheral area of ​​the flexible membrane main valve core 13 is connected to the valve casing of the manual and automatic integrated piezoelectric valve, thereby forming the flexible membrane main valve core 13 The fixed part 131 of the main valve inlet 1 is connected to the water inlet of the valve, and the main valve outlet 4 is connected to the water outlet of the valve. With the flexible membrane main valve core 13 as the b...

Abstract

The invention discloses an manual-automatic integrated piezoelectric valve. The manual-automatic integrated piezoelectric valve comprises a flexible film main valve element. A manual valve element isdriven manually and thus controlled manually, an automatic valve element is driven by a piezoelectric actuator and thus controlled automatically, the automatic valve element and the manual valve element are used for controlling connecting and disconnecting of an automatic pilot hole and a manual pilot hole correspondingly, and then the action of the flexible film main valve element is controlled so as to achieve conducting and shutoff of the valve. The manual-automatic integrated piezoelectric valve has significant progressiveness.

Description

technical field [0001] The invention relates to a manual-automatic integrated piezoelectric valve, which belongs to the technical field of piezoelectric valves. Background technique [0002] In order to add a manual function to the piezoelectric valve, according to the prior art, there are two technical solutions to choose from. [0003] The first is to connect a manual valve in parallel with the outside of the piezoelectric valve. [0004] The second is to set two parallel water flow passages in the piezoelectric valve, one of which is a traditional piezoelectric valve part driven and controlled by a piezoelectric driver, and a manual main spool is set on the other passage, through manual control The action of the spool then controls the on-off of this passage. [0005] The principle of operation of the piezoelectric valves described above is essentially the same. [0006] The manual and automatic piezoelectric valve designed by relying on the existing technology is equi...
