Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1:

as shown in fig. 1, an integrally formed solenoid valve assembly includes a housing 1. The housing 1 is made of a non-metallic material, and is generally made of high-temperature-resistant flame-retardant PVC rubber as a raw material. The bottom of the shell 1 is integrally formed with a mounting seat 2. The mounting seat 2 is used for realizing bolt connection with a valve seat of the electromagnetic valve.

A plunger 3 is provided inside the housing 1. The plunger 3 is embedded with a valve needle 4. Two springs 5 are arranged between the needle 4 and the plunger 3. One of the springs 5 is provided with a wire guide sleeve 6 at both sides. Meanwhile, an enameled wire 7 is arranged around the inside of the shell 1. When the enameled wire 7 is electrified, a radial magnetic field is generated. The valve needle 4 with the wire guide sleeve 6 is driven to move upwards under the action of magnetic force, so that the electromagnetic valve is opened, and after the electrification is stopped, the valve needle 4 returns to the original position under the action of the spring 5, so that the electromagnetic valve is closed.

One side of the shell 1 is provided with an electric wire 8, and the electric wire 8 is used for electrifying the enameled wire 7.

In practical use, compared with the general welding type solenoid valve assembly, the solenoid valve assembly is formed by firstly installing the plunger 3, the spring 5, the valve needle 4 and the wire guide sleeve 6, then winding the enameled wire 7, and directly and integrally molding the housing 1 through an injection molding process. The shell 1 is integrally formed without welding, so that the problems of insufficient welding and desoldering do not exist, and the problem of corrosion of the shell 1 does not exist at the same time. The integrally formed solenoid valve assembly can avoid the leakage problem between the inner enameled wire 7 and the outer shell 1.

Example 2:

as shown in fig. 2, 3, 4 and 5, the difference from embodiment 1 is that a mounting structure 9 is provided on a mounting base 2 of an integrally molded solenoid valve assembly. The mounting structure 9 comprises a mounting hole 10 provided on the mounting socket 2. An annular groove 11 is arranged in the mounting hole 10. The ring groove 11 is communicated with a clamping groove 12. The snap-in groove 12 is communicated with the ring groove 11 and the outside. A clamping groove 13 is arranged on one side of the clamping groove 12.

Correspondingly, a mounting rod 14 is arranged in the mounting hole 10, and the tail end of the mounting rod 14 is clamped with the jack on the valve seat. The other side of the mounting rod 14 is provided with a snap-in block 15 which is matched with the snap-in groove 12. The snap-in block 15 snaps into the snap-in groove 12 and continues to move to the position of the ring groove 11. The mounting rod 14 is then rotated so that the mounting rod 14 drives the snap-in block 15 to rotate in the annular groove 11. Correspondingly, the mounting rod 14 is provided with a clamping block 16 corresponding to the clamping groove 13. The clamping block 16 is provided with a sealing strip (not shown in the figure). The sealing strip is used for making interference fit joint between joint piece 16 and the joint groove 13, can prevent simultaneously that the vibrations that produce at the solenoid valve during operation from producing the influence to the installation of installation pole 14, prevents that installation pole 14 and mount pad 2 from breaking away from.

Preferably, fixing grooves 17 matched with the clamping blocks 15 are arranged on two sides of the ring groove 11. When the mounting lever 14 is further rotated so that the click block 16 clicks into the click groove 13, the click block 15 clicks into the fixing groove 17. At this time, the interference fit clamping block 16 and the clamping groove 13 prevent the installation rod 14 from continuing to rotate, so that the installation rod 14 is fixed on the installation seat 2, and the connection of the valve seat and the electromagnetic valve assembly is completed.

If the parts such as the enameled wire 7 in the electromagnetic valve shell 1 are damaged and the electromagnetic valve component needs to be replaced, the mounting plate is pulled outwards by force, so that the clamping block 15 is separated from the fixing groove 17. The process is reversed so that the mounting stem 14 is unseated and replaced with a new solenoid operated valve assembly for installation.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications without inventive contribution to the present embodiment as required after reading the present specification, but all of them are protected by patent law within the scope of the present invention.
