Abstract

The utility model discloses a cutting pressure type liquid valve. The thin end of a step type circular pipe valve body 1 is positioned with a switch handle 2 via a positioning shaft 8, and the side part of the switch handle 2 is provided with a positioning plate 4 which is provided with a concave slot 5. The lower arm of the switch handle is provided with a spring ball latch door catcher 6 corresponding to the concave slot, a rubber bent pipe 3 is sheathed in a valve body 1, and the upper end of the rubber bent pipe 3 can be in the pressure of the lower arm of the switch handle 3. The utility model has the characteristics of easy manufacturing, low cost, long service life, tight closing and short opening and closing times.

Description

Cut the pressure type Liquid valve

The utility model relates to a kind of valve of controlling liquid flow, is specially a kind of section pressure type Liquid valve.

At present, making in the society and use in the valve of controlling liquid flow many kinds are arranged, can be divided into spiral valve and ball type valve door substantially, though spiral valve can effectively be realized the task of controlling liquid flow, but having close, the screw port place of being not closed completely should damage, switching time is long, and the defective that working life is short is though the more spiral valve of ball type valve door has long service life, close tight, the characteristics that switching time is short, but really have the cost height, be difficult for the defective of manufacturing.

Task of the present utility model is to overcoming the defective of above-mentioned valve, provides a kind of and is easy to that manufacturing, cost are low, long service life, closes novel section pressure type Liquid valve tight, that switching time is short.

Task of the present utility model takes following scheme to realize.

Accompanying drawing has provided structural representation of the present utility model.

In the accompanying drawings, (1) is that valve body, (2) switch knob, (3) are sealed mouth for liquid entering hole, (10) for liquid outlet, (11) for positioning shaft, (9) for internal thread, (8) for spring latch lock, (7) for Baltimore groove, (6) for positioning plate, (5) for curved rubber hose, (4).

Below will be described as follows concrete structure of the present utility model with reference to the accompanying drawings:

With reference to the accompanying drawings, valve body (1) is a step pipe, at the inwall of step pipe butt end On be provided with internal thread (7), and form water inlet (9), pass through at the tube wall of its taper end Locating shaft (8) is positioned with the bent switching handle (2) that the top is circular arc, and make its this open The circular arc top of closing handle (2) places from the lower wall twice rubber of valve body (1) and becomes pipe (3) The wall thickness place, be provided with at the sidepiece of the underarm of switch knob (2) and be equipped with Baltimore groove (5) Fan-shaped location-plate (4), on the underarm of switch knob (2) and be in corresponding to location-plate The place, centre of the Baltimore groove (4) (5) is provided with spring latch lock (6), at rubber The end of bend pipe (3) is provided with seal (11), makes it with seal (11) Curved rubber hose (3) is sleeved in the valve body (1) by the taper end of valve body (1), and makes its rubber Seal (11) on the glue bend pipe (3) places on the step of valve body (1), and its rubber is curved The upper end of pipe (3) is under the pressure of underarm of switch knob (2), curved rubber hose (3) The other end place outside the valve body (1), form liquid outlet (10).

Below will be described as follows using method of the present utility model with reference to the accompanying drawings:

When using the utility model, by the internal thread (7) on the valve body (1) valve body (1) and water pipe are linked together, and by the sealed mouth on water pipe and the rubber pipe (3) with rubber pipe (3) fit sealing in valve body (1), make liquid entering hole (9) and liquid outlet (10) form path, when need are opened valve, along A to rotary switch handle (2) and spring latch lock (6) is inserted in the Baltimore groove of diverse location position, at this moment curved rubber hose (3) is upspring automatically, make liquid entering hole (9) and liquid outlet form path, thereby realize opening the task of valve, can be in this process according to the size of required fluid flow, determine the angle of swing of switch knob, spring latch lock (6) is entered in the pairing Baltimore groove (5), just can realize controlling the needs of different flow liquid, when needing throttle down, need only the task that can realize throttle down by the said process operation.

-the utlity model has following evident characteristic: owing to adopted switch knob rotary push rubber pipe as on-off mode, replaced spiral way,, closed tight characteristics so it is short to have long service life, switching time, have simultaneously simple in structure, easily processing, the advantage that cost is low.

In sum, can effectively realize task of the present utility model, be easy to for society provides a kind of that manufacturing, cost are low, long service life, close novel section pressure type Liquid valve tight, that switching time is short.
