Description
Technical Field
The utility model relates to an electromagnetic valve, in particular to a suspension electromagnetic valve.
Background
The existing electromagnetic valve has the defects that the connection between the magnetism isolating pipe and the valve body is not firm enough due to the fact that the magnetism isolating pipe and the valve body are connected through welding and/or interference fit.
Disclosure of Invention
In order to solve the problems, the utility model provides a suspension electromagnetic valve, wherein the connection between a magnetism isolating pipe and a valve body is firmer.
The technical scheme of the utility model is as follows:
the suspension solenoid valve is a normally closed solenoid valve and comprises a magnetism isolating pipe, a fixed iron, a spring, a movable iron component, a valve body, a valve seat, a ring filter screen and an end filter screen, wherein the magnetism isolating pipe, the fixed iron, the spring, the movable iron, a push rod, the valve body, the valve seat, the ring filter screen and the end filter screen are assembled together; the electromagnetic valve is arranged in the mounting hole on the base; the outer periphery of the valve body is provided with an annular boss, the magnetism isolating pipe is sleeved on the upper part of the valve body, and the lower end of the magnetism isolating pipe is pressed on the annular boss at the outer periphery of the valve body;
an annular step is arranged in the mounting hole on the base;
when the electromagnetic valve is installed in the installation hole on the base, the annular boss on the periphery of the valve body is supported on the annular step in the installation hole on the base, the base is extruded, and the installation hole opening part of the base deforms and presses the annular boss on the lower end of the magnetism isolating pipe and the periphery of the valve body.
The opening part of the mounting hole on the base is deformed and pressed on the lower end of the magnetism isolating pipe, and the contact surface of the mounting hole and the magnetism isolating pipe is a conical surface or a stepped curved surface; the design of the conical surface or the stepped curved surface effectively increases the compression contact area and avoids loosening.
Considering that the mounting hole part of the base is deformed, if the mounting hole part is only pressed on the lower end of the magnetism isolating pipe, the relative displacement between the lower end of the magnetism isolating pipe and the annular boss at the periphery of the valve body cannot be effectively limited, and further, the lower end of the magnetism isolating pipe and the annular boss at the periphery of the valve body are staggered to form an annular step, so that the mounting hole part on the base is deformed and pressed on the annular step formed by the lower end of the magnetism isolating pipe and the annular boss at the periphery of the valve body, the relative displacement between the lower end of the magnetism isolating pipe and the annular boss at the periphery of the valve body can be effectively limited, and the connection of the lower end of the magnetism isolating pipe and the annular boss at the periphery of the valve body is firmer.
The electromagnetic valve has the advantages that the electromagnetic valve is reasonable in design and simple in structure, the magnetic isolation pipe structure is improved, the lower end of the magnetic isolation pipe is pressed on the annular boss on the periphery of the valve body, so that when the electromagnetic valve is installed on the base, the base is deformed to press the annular boss on the periphery of the magnetic isolation pipe and the lower end of the valve body, and the magnetic isolation pipe is reinforced (of course, welding and interference fit connection can be simultaneously considered), so that the connection between the magnetic isolation pipe and the valve body is firmer.
