CN2066924U - Rotary ring type non-pressure automatic non-discharge closing valve - Google Patents

Abstract

The utility model relates to a rotary ring type non-leakage valve, particularly a non-leakage automatically closing valve without pressure. The utility model is characterized in that the operation of a rotary ring is simple and flexible; after a spring is installed, when the medium pressure is smaller than the operating pressure, the rotary ring can automatically rotate to a closed position. Thus, when the water supply is cut off, the bad results caused by forgetting to switch off a faucet, etc. can be avoided. The automatically closing device can be inserted or drawn out by hand according to users' requirements. The utility model has the advantages of no leakage, reliable closure, bidirectional circulation, flow regulation, simple fabrication, low cost, beautiful appearance, durability and convenient use. The utility model can be dismounted by hand.

Description

Rotary ring type non-pressure automatic non-discharge closing valve

The utility model provides not leakage valve of a kind of revolving ring type that has improved.

China disclosed my " revolving ring type is not let out stop valve " on August 23rd, 89 in CN2043308U, it is characterized in that: on the basis of former stop valve, change spiral shell and execute pay to open and close and be the revolving ring type keying, make valve opening and closing flexible rapidly, and can two-way circulate, do not leak ... but do not have to wave its advantage unfortunately, increase robot device.

For example: when cutting off the water in the daily life, forget and turn off the tap, can cause when coming water again and spread unchecked.The residential quarter do not wish like this, industrially more do not allow like this.

For additional above blemish in an otherwise perfect thing, and make the easier assembling of this valve processing simpler, purposes is wider, provides a kind of here and utilizes elastic force and pressure medium official post change to automatically reset, and the nothing of throttle down is leaked automatic valve.

Fig. 1, do not close automatically and do not leak water tap for revolving ring type has pressure.

Fig. 2,, revolving ring type do not close not leakage valve automatically for having pressure.

Fig. 3, be that valve is flanged, the change schematic representation of face dress steel ball then.

The utility model is finished like this:

Referring to Fig. 1,2,3: a kind of self-acting valve that do not leak, by valve body 1, valve gap 2, end socket 3, compositions such as change 4 and winding type seal bowl 5.End socket 3 likeness in form " mountain ", tail end can be adorned steel ball 8, and valve gap 2 is overlapping end socket 3 and is pressing the limit of seal bowl 5.Valve gap 2 can be fixing with screw thread or positioning ring 6 with valve body 1.Change 4 is enclosed within the cylindrical of valve body 1, can adorn between them steel ball 8 '.The axially locating of change 4 can limit with positioning ring 6.Can annotate scale in the change 4, regulate flow, the inside groove of change 4 can fill up a sheetmetal 7; One of the steel ball 8 of valve body 1 two ends on can flanged 1 ' valve body 1 ' can adorn or adorn some side by side.When valve was vertically installed, steel ball 8 also can be adorned in the side of change 4 ", valve one end is if open formula, as water tap, can not adorn on the valve body 1 steel ball 8 '.

Because pressure medium always holds up end socket 3 in the valve, and the inside groove of change 4 is spiral of Archimedes, as long as rotation change 4, the inside groove of change 4 can be pressed inward gradually or loosens the tail end of end socket 3, thereby regulates flow and switch valve.

In change 4 one sides several pits 9 are arranged, on the valve body 1 of these pits 9, circle has the spring 10 of a dish multi-turn number vis-a-vis.The two ends of spring 10 all can be inserted in the pit of valve body 1 at ordinary times, and robot device is inoperative.After an end of spring 10 changes in a certain pit that inserts change 4, spring 10 always attempts change 4 is threaded to the position of closing, just pressure medium makes the frictional force of the tail end of end socket 3 and change 4 greater than spring force at ordinary times, change 4 can be threaded to any angle and do not rebounded, but when pressure medium during less than working pressure, spring 10 makes change 4 be threaded to the position of closing.

Like this, be equipped with at needs and close automatically in the pipeline of facility, as the poisonous medium of forgetting chemical industry department when turning off the tap after cutting off the water is when overflowing, when gas stove stops working, in the shower during anoxic ... this valve has possessed the good condition as an actuator.

Spring 10 can be made with steel, copper, metal alloy or other non-metallic elastic materials.

The utility model does not have leakage, closes reliably, can two-way circulate, and regulates flow, makes simply, and cost is low, attractive and durable, and is easy to use, can free-hand dismounting.

Claims (3)

1, a kind of revolving ring type leakage valve not is made up of valve body 1, valve gap 2, end socket 3, change 4 winding type seal bowls 5, spring 6 etc., it is characterized in that: end socket 3 be "

" shape, valve gap 2 is overlapping end socket 3 and is pressing the bowl limit of winding type seal bowl 5, and spring 10 circles are on the valve body 1 of change 4 one sides.

2, not leakage valve according to claim 1 is characterized in that: valve gap 2 and valve body 1 can connect or fixing with positioning ring 6 with screw thread.

3, not leakage valve according to claim 1, it is characterized in that: change 4 can be annotated scale, inside groove can fill up sheetmetal 7, interior circle and then face can adorn steel ball 8 ' and 8 ".
