Problems solved by technology

In addition, when the diaphragm type solenoid valve is applied to devices other than such a dialysate supply device, there is also a problem that when the solenoid does not work normally, the valve does not operate correctly even if the coil is energized. Perform opening and closing actions, and the required opening and closing valve cannot be implemented in an emergency

Embodiment Construction

[0024] Hereinafter, embodiments of the invention will be described with reference to the drawings.

[0025] Such as Figure 1 ~ Figure 4 As shown, the diaphragm type solenoid valve according to the first embodiment of the present invention has a cylindrical appearance as a whole, and is composed of a housing 1 and an electromagnetic solenoid 6. The housing 1 connects the valve body 2 and a plurality of ring members. 3, 4, 5 are stacked and integrated, and the electromagnetic solenoid 6 is installed on the upper part of the housing 1.

[0026] At the center of the valve main body 2 is provided a flow passage 7 extending in the vertical direction, and convex upper valve seats 7 a and lower valve seats 7 b are formed at both ends of the flow passage 7 . In addition, the valve main body 2 is provided with first to third flow passage openings 8, 9, 10 extending in the horizontal direction, wherein the first flow passage opening 8 communicates with the third flow passage opening 10...

Abstract

Provided is an electromagnetic valve which can be switched manually from the outside in an emergency, etc. This diaphragm type electromagnetic valve is provided with: a housing (1) having a pluralityof ports (8, 9, 10); and an electromagnetic solenoid (6) mounted on the upper part of the housing (1). An upper valve body (11) capable of coming into contact with and separating from an upper valve seat (7a) is secured to the plunger (23) of the electromagnetic solenoid (6), and a lower valve body (13) capable of coming into contact with and separating from a lower valve seat (7b) is secured to adrive-receiving body (15) connected to the plunger (23). The bottom surface of the housing (1) is provided with a through-hole (17) which allows access to the drive-receiving body (15) from the outside. When a failure, etc. occurs in the coil (22) of the electromagnetic solenoid (6), a tool (30) is inserted into the through-hole (17) to push up the drive-receiving body (15), and the plunger (23)is moved to a lifted position by means of the drive-receiving body (15) and a push rod (26). As a result, the upper valve body (11) is separated from the upper valve seat (7a) to open the upper valveseat (7a).

Description

technical field [0001] The present invention relates to an electromagnetic valve that opens and closes a valve by energizing an electromagnetic solenoid installed in a case. Separated diaphragm type solenoid valve. Background technique [0002] Solenoid valves of medical instruments, various analytical instruments, etc. usually use a solenoid valve with a diaphragm arranged between the fluid flow path in the housing and the electromagnetic solenoid to prevent the electromagnetic solenoid from being installed on the upper part of the housing. The wear powder of the tube is mixed into the fluid flowing in the housing (for example, see Patent Document 1). [0003] In such a diaphragm type solenoid valve, a valve element is mounted on the lower end of a plunger, which is a component of an electromagnetic solenoid, and the outer edge of the diaphragm integrated with the periphery of the valve element is sandwiched and fixed on the Between the casing and the electromagnetic sole...
