Abstract

The utility model relates to an adjustable pressure limiting automatic valve with magnetic force for a sprayer. The utility model which is composed of a valve body, a valve core, a water inlet pipe, and a water outlet pipe is characterized in that a guide rod which penetrates through a limiting plate in a cavity body is fixed on a supporting plate, and the water outlet pipe is connected with the right part of the cavity body; a sealing head is arranged on the connecting position of the spout of the water inlet pipe and the cavity body; the cone bottom of the cone sealing head is clamped and inlaid in a right circular annular magnetic block which is fixed on the supporting plate, and a left circular annular magnetic block is sheathed outside the spout of the water inlet pipe and is fixedly clamped by a retainer ring. The utility model which can be used for spraying in a pressure limiting mode and can adjust limited pressure has the advantages of high efficiency, automatic opening and closing, simple operation, and simple use.

Description

Sprayer adjustable magnetic pressure limiting self-acting valve

The utility model relates to a kind of pressure limiting device, specifically a kind of sprayer adjustable magnetic pressure limiting self-acting valve.

At present the valve that uses on the sprayer is that manually-operable opens and closes, thereby can not limit the poor efficiency spraying under the low pressure, simultaneously because frequent operation, seal ring is is very easily worn and torn and causes leakage.

The purpose of this utility model provides a kind of energy pressure limiting spraying, the sprayer adjustable magnetic pressure limiting self-acting valve that automatic opening-closing is adjustable.

The purpose of this utility model is realized by following technological scheme.

The utility model is made up of valve body, spool, intake pipe and outlet pipe, it is characterized in that:

A, described valve body comprise cavity and guide rod, and the limiting board that guide rod passes in the cavity is fixed on the supporting plate, and outlet pipe is connected in the cavity right part;

B, spool comprise self-closing end socket of magnetic and a pair of ring magnetic patch, the self-closing end socket of magnetic places water inlet pipe mouth and cavity joining place, in the right ring magnetic patch of inlay card at the bottom of the awl of cone end socket on being fixed on supporting plate, left side ring magnetic patch is placed in outside the intake pipe mouth of pipe, by the back-up ring fixing of built-in thrust spring.

It is contained on the sprayer, operate its pressure cylinder and make its supercharging, the self-closing end socket pressurized of magnetic is opened, carry out the normal spraying under the authorized pressure, turn the magnetic force of a pair of annular magnetic interblock of the self-closing end socket of back-up ring can regulate magnetic, its authorized pressure is reached be desirably suitable, reduce to pressure that certain limit will make the self-closing end socket of magnetic lose enough to push open and self-closing, promptly stop spraying when pressure.

But the utility model has the advantages that not only pressure limiting spraying, raise the efficiency, and the can regulate pressure limiting, automatic opening-closing.Moreover operate, use simply, simultaneously not easy to wear, long service life.

Fig. 1 is the utility model structural representation.

By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.

Embodiment:

(referring to Fig. 1) processing one comprises the valve body 1 of cavity 5 and guide rod 6, and the limiting board 8 that guide rod 6 passes in the cavity 5 is fixed on the supporting plate 7, and outlet pipe 4 is connected in cavity 5 right parts; Form spool 2 by self-closing end socket 9 of magnetic and a pair of ring magnetic patch 10, the self-closing end socket 9 of magnetic places water inlet pipe mouth and cavity joining place, in the right ring magnetic patch 10 of inlay card at the bottom of the awl of cone end socket 11 on being fixed on supporting plate 7, left side ring magnetic patch 10 is placed in outside intake pipe 3 mouths of pipe, by back-up ring 12 fixings of built-in thrust spring 13.
