CN201225409Y - Cock valve mounted on automobile warm air water tank - Google Patents

Abstract

The utility model discloses a stopcock installed on a heater water tank of an automobile. The stopcock consists of a feed valve body, a feed valve body gasket ring, a spring strip, a feed valve cover, a feed valve core and a feed valve rocker. The stopcock has the technical scheme that the feed valve body is provided with communicated feed passages, the inner part of the feed valve body is an L-shaped hollow tube, the corner of the inner part is provided with the feed valve core which is fixed by the spring strip and the gasket ring and can rotate in small angles, the feed valve core is driven by the rocker to rotate, and the rotating movement of the feed valve rocker drives the feed valve core to rotate. When the water outlet of the feed valve core and the opening of the feed valve gasket ring are completely staggered, the water valve closes completely; when the water outlet of the feed valve core and the opening of the feed valve gasket ring are completely aligned, the water valve opens completely. The stopcock eliminates the influence of idle motion caused when drawing wires are connected, ensures that the stopcock completely closes, avoids leakage and guarantees the refrigerating effect of air-conditions.

Description

A kind of stopcock that is installed on the automobile warm-air water tank

Technical field

The utility model relates to a kind of control valve unit, particularly relates to a kind of stopcock that is installed on the automobile warm-air water tank.

Background technique

Water valve as one of temperature regulation power unit of automobile warm-air air-conditioning plays important effect when air-conditioning is opened, water valve is in case leak in occurring, to occur this cooled air be heated once more, directly influence the refrigeration of car air conditioner, will not have refrigeration fully when serious.At present, the water valve majority that can directly be fixed on the warm braw water tank is leaf valve, the inlet valve valve shaft of this valve links to each other with the inlet valve valve block, the inlet valve valve shaft is driven by wire drawing or other mechanism, the shortcoming of this valve be if the wire drawing that links to each other with inlet valve be connected have slightly loosening, the inlet valve valve block will no longer fit tightly with the inlet valve seal ring, and leaking will appear in water valve, also not have effectively to solve at present the method for similar shortcoming.

Summary of the invention

The influence of the idle stroke of bringing when connecting wire drawing in order to eliminate guarantees that water valve can cut out a kind of stopcock that is installed on the automobile warm-air water tank of avoiding leaking and designing fully.

The utility model is mainly by housing, seal ring, spring sheet, the inlet valve valve gap, inlet valve spool and rocking arm are formed, and the inlet valve housing has the intake tunnel that is interconnected, it is characterized by: there is an inlet valve spool in corner at " L " type passage, the inlet valve spool is provided with passage, and seal ring is fixed on enclosure interior with the inlet valve spool, drives the inlet valve valve core rotation by rocking arm.

The beneficial effects of the utility model: this stopcock comes switch by the rotation of spool, can eliminate the influence of the idle stroke of bringing when connecting wire drawing, guarantees that water valve can cut out fully, avoids leaking, and has guaranteed the refrigeration of air-conditioning.

Fig. 3 is the utility model full open position side view.

Fig. 4 directly is fixed on warm braw water tank schematic representation for the utility model.

Embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of stopcock that is installed on the automobile warm-air water tank, by housing 1, seal ring 2, spring sheet 3, inlet valve valve gap 4, inlet valve spool 5 and rocking arm 6 are formed; Its technological scheme is: inlet valve housing 1 has the intake tunnel that is interconnected, its inside is the blank pipe of " L " type, there is an inlet valve spool 5 in corner of portion within it, but by spring sheet 3 and seal ring 2 fixing small angle rotations, inlet valve spool 5 is by rocking arm 6 driven rotary, drive the rotation of inlet valve spool by rotatablely moving of rocking arm 6, water valve cuts out (accompanying drawing 2) fully when the mouth of the water outlet of inlet valve spool and inlet valve seal ring staggers fully, fully the timing water valve is all opened (accompanying drawing 3) when the water outlet of inlet valve spool and inlet valve seal ring.This water valve directly is fixed on the warm braw water tank, sees shown in the accompanying drawing 4, and stopcock water valve 7 is in the warm braw tank top, and the middle big sealing ring 8 that adopts seals, and the inlet valve driving mechanism for rocker arm drives.Consider the influence of wire drawing idle stroke, be not when allowing the inlet valve rocking arm move to the two ends break point fully in design, water valve just cuts out, but the place before moving to break point is just closed fully, can eliminate the influence of the idle stroke of bringing when connecting wire drawing like this, guarantee that water valve can cut out fully.

Claims (1)

1, a kind of stopcock that is installed on the automobile warm-air water tank, mainly by housing, seal ring, spring sheet, inlet valve valve gap, inlet valve spool and rocking arm are formed, the inlet valve housing has the intake tunnel that is interconnected, and it is characterized by: there is an inlet valve spool in corner at " L " type passage, and the inlet valve spool is provided with passage, seal ring is fixed on enclosure interior with the inlet valve spool, drives the inlet valve valve core rotation by rocking arm.
