Abstract

The utility model provides a controllable tap of no water, it has adopted by spheroid, the sealing washer of establishing separately and the valve body that the ejector pin constitutes and by camshaft, balanced switch the controllable device that constitutes, under anhydrous state, the camshaft changes under balanced switch effect along with water pressure, makes the case close rapidly, is equipped with the spline delivery port at the case lower extreme, makes the hydroenergy that contains impurity smooth the flowing unimpededly rapidly. The tap is flexible and reliable in use, ensures the closing effect in the water-free state, and is easy to assemble, replace and maintain due to the valve core.

Description

Controllable water tap when water cut-off

The utility model relates to a kind of anhydrous controlled tap.

Analysis, the disclosed anhydrous water tap of closing automatically, there is following defective in its structure, one, spool adopts existing structure for water tap, is fixedly connected on the seal ring of awl bar upper end, and is yielding in reciprocating action, wearing and tearing, do not weigh and be difficult to play sealing effect, and more difficultly reach anhydrous purpose of closing automatically, and particularly in water, contain the grains of sand or other impurity when higher, easily stop up taper hole, do not weigh that current are obstructed, more can't reach anhydrous purpose of closing automatically; Its two, under the state that hydraulic pressure constantly changes, particularly hydraulic pressure hour, the variation when its bent axle is difficult to adapt to less hydraulic pressure state is difficult to close automatically.

The purpose of this utility model is to provide a kind of energy reliable and be applicable to anhydrous controlled tap under the different quality state.

The utility model is for solving above-mentioned task, adopt following structure to realize: the spool that will be fitted in the outlet pipe inner chamber has adopted the push rod by end in contact under spheroid, seal ring and the spheroid to constitute, the spool lower end is provided with the spline water outlet, push rod lower end by spline water outlet center contacts with camshaft, the camshaft the other end connects balance cock, and the axis of the axis of camshaft and outlet pipe is mutually 90 °.

Below will come the utility model is described in detail by drawings and Examples:

Accompanying drawing 1 is structure master's sectional view of the present utility model

Fig. 2 is the A-A sectional drawing of Fig. 1

Valve body (5) adopts casting and machine to add to combine and makes, and valve body is provided with intake pipe (1) and outlet pipe (9), two tube hub line vertical line and connections.The spool that is contained in the outlet pipe epicoele is made of spheroid (6), seal ring (7) and push rod (8).Spheroid adopts glass to make or adopt other nonmetallic material to make, the seal ring that is positioned under the spheroid adopts the material of corrosion-and high-temp-resistant to make, and seal ring adopts drive fit, and it is positioned at the chamber, the push rod upper end contacts with spheroid, the center hole of lower end spline water outlet (10), spline water outlet and valve body are made one and are adopted three slotted eyes for well.The push rod lower end surface contacts with camshaft (3), camshaft one end is for adapting to the dedicated cam that variation in water pressure is made, in the camshaft the other end drive fit balance cock (2) is arranged, establishing switch is that a counterweight handle, camshaft are contained in end cover (4) hole, and rotary end cover is threadedly connected on the valve body.

Under opening state, current flow out through the outlet pipe cavity of resorption via the seal ring taper hole and the mouth of a river, spline limit (10) by intake pipe (1), particularly all can flow out through the spline water outlet smoothly the current that contain the grains of sand and other impurity, at this moment, under hydraulic action, the push rod lower end surface contacts with cam, simultaneously, balance cock (2) is in same direction (switching position shown in the figure) with camshaft, when variation in water pressure is extremely anhydrous, under on-off action, from middle rotation, a bar and spheroid move down and reach sealing effect camshaft immediately immediately.

The utility model adopts novel spool and cam-operated switch structure, makes its using scope extensive, is not only applicable to the water quality that purified, and more be applicable to water quality unprocessed or that impurity is more, action is flexibility and reliability very, and the part convenient maintenance and replacement can be closed under anhydrous state reliably.

Claims

1, a kind of anhydrous controlled tap, it is by valve body (5), intake pipe (1), outlet pipe (9) and spool are formed, and it is characterized in that being fitted in the spool of outlet pipe (9) inner chamber, by spheroid (6), the push rod (8) of end in contact constitutes under seal ring (7) and the spheroid, the spool lower end is provided with spline water outlet (10), and the push rod lower end by water outlet (10) center contacts with camshaft (3), and switch (2) and camshaft axis that the camshaft the other end connects balance become 90 ° with the outlet pipe axis.

2, anhydrous controlled tap as claimed in claim 1 is characterized in that described balance cock (2) is a counterweight handle.

3, anhydrous controlled tap as claimed in claim 1 is characterized in that seal ring (7) adopts high temperature resistant and resistant material is made and drive fit is loaded in the pipe.
