Guide electromagnetic valve with hand push button

Abstract

The invention discloses a leading type electromagnetic valve with a hand-operated button, which comprises a main valve body, a check filter valve component, a movable valve core component, a return spring, a leading valve body component, an electromagnetic valve and a hand-operated valve. The check filter valve component is arranged on a front passage inside the main valve body. A back passage inside the main valve body is divided into an upper passage and a lower passage, the movable valve core component with an eyehole is arranged at an inlet of the upper passage, the valve body at an outlet of the upper passage is connected with the leading valve body, and a seal cavity is formed between the movable valve core component and the leading valve body. One end of the return spring is supported on the leading valve body, and the other end of the return spring is supported on the movable valve core component capable of sealing or opening an inlet of the lower passage. A front inlet and a back inlet arranged on a passage of the leading valve body are both connected with the passage of the main valve body, an outlet of the passage of the leading valve body is connected with the outlet end of the main valve body, the electromagnetic valve is arranged on the passage of the leading valve body, the hand-operated valve is arranged on the back inlet of the passage of the leading valve body, and an outlet of the lower passage is connected with the outlet end of the main valve body. The leading type electromagnetic valve has the advantages of convenient maintenance and repair, compact structure, small volume and raw material conservation. The normal use of the valve can be controlled even during power failures.

Description

technical field [0001] The invention relates to a pilot electromagnetic valve, in particular to an electromagnetic water valve used for a squat urinal induction flusher among induction sanitary ware. Background technique [0002] The electromagnetic water valve used in the existing squatting toilet induction flusher adopts a diaphragm structure without a water cut-off mechanism. If the electromagnetic valve is repaired, the main water supply valve must be closed before proceeding, which is very inconvenient and also Without a filter, if it is added with a filter and a stop valve, the volume of the whole product is relatively large and there are many consumables. And when the present electromagnetic valve is applied to the occasion of automatic flushing, its manual function relies on electronic triggering, if there is no electricity, then the electromagnetic valve and the manual operation function all lose their effect. Contents of the invention [0003] The technical prob...

[0002] The electromagnetic water valve used in the existing squatting toilet induction flusher adopts a diaphragm structure without a water cut-off mechanism. If the electromagnetic valve is repaired, the main water supply valve must be closed before proceeding, which is very inconvenient and also Without a filter, if it is added with a filter and a stop valve, the volume of the whole product is relatively large and there are many consumables

Moreover, when the current solenoid valve is used in automatic flushing occasions, its manual function is triggered electronically. If there is no electricity, both the solenoid valve and the manual operation function will be useless.
