Abstract

The utility model relates to a safety cover for automobile water tanks, which is characterized in that the middle between the inner cover and the outer cover of a water tank cover is provided with a lantern ring seat; the lantern ring seat is provided with middle rings; the upper part of the side wall of the lantern ring seat is provided with an air leakage mouth; the inner cover of the original air leakage port is connected with a duct; the duct is provided with an air leakage valve which comprises a valve cover, a rotary valve body, a handle. Before opening the water tank cover, an operator opens the air leakage valve to exhaust vapor first in order to reduce the air pressure of a water tank, and then screws the outer cover, so the operator can not be scalded by vapor. The utility model has an obvious effect of avoiding the operator scalding and has the advantages of simple structure and easy operation.

Description

Safety cover for automobile water tank

The utility model relates to the improvement of automobile water tank lid.

When the phenomenon that causes producing in the water tank high temperature, lack of water is for a long time crossed in the garage, the case lid of will fetching boiling water this moment, check whether lack of water or damage.Existing water tank cover structure as shown in Figure 1, tank lid is combined by enclosing cover 1 and inner cap 6, covers outward and is provided with plunger 4, and spring 2 and rubber seal 3 are housed on the plunger, after enclosing cover and inner cap screw by screw thread, force spring 2 to drive the relief opening 5 that plungers 4 compress rubber pads 3 are blocked inner cap.There is leakage port 7 in the inner cap outside, economizes small amount of steam and back down rubber seal 3 a little when high temperature, releases by leakage port.But when covering over the operator strikes with the hand, high-temperature steam moment scurries out from the gap, staff can be scalded.

The purpose of this utility model is to provide a kind of radiator safety head, to reduce the possibility of being scalded by high-temperature steam when the operator fetches boiling water case lid.

The utility model radiator safety head is achieved in that a cover ring seat is set between the inner cap of automobile water tank lid and enclosing cover, ring in one is arranged in the middle of the ring seat, in cover ring seat sidewall, locate on the ring, offer a leakage port, packing ring is equipped with in middle ring below, for the usefulness of sealing; At the former leakage port of inner cap position connecting duct, so that cannot being directed at imitatively, steam in the water tank do not hinder the work part, and on the close conduit of tank lid, be provided with, have the rotary valve of guide hole and the gas bleeder valve of handle by the cylinder valve pocket; The cover ring seat is suitable for reading articulating device with enclosing cover seven, and end opening has the articulating device with the inner cap coupling.

This radiator safety head rotated gas bleeder valve earlier before opening, the interior part steam of water tank is released by conduit, reduced the pressure of water vapor in the water tank, and then the enclosing cover of outwarding winding, steam just can not gone out in moment suddenly in the water tank, cause the operator to be scalded, the Security when having increased operation.Operation is after (Ru Jiashui) finish, and builds enclosing cover and makes snifting valve and close, and is the sealing shape in the water tank again, operates very easy.This product is through the trial-production test, and effect is fairly obvious, and the user beats has no injured danger when covering, and can transform existing tank lid easily.

Be described further below in conjunction with accompanying drawing

Fig. 1 is the structure of existing tank lid;

Fig. 2 is the cover ring seat stereo dissected figure in the safety water tank cover

Fig. 3 is the overall structure schematic representation of safety tank lid

Fig. 4 is the structural representation of this tank lid gas bleeder valve

Can see that by Fig. 1 raw water box lid is made of enclosing cover 1, inner cap 6, cover and be provided with spring 2, plunger 4, rubber seal 3, inner cap middle part and be relief opening 5 that sidewall has leakage port 7 outward; Fig. 2 has showed the structure of cover ring seat 8, and ring 9 in cover ring seat middle part is provided with is equipped with packing ring 10 under the middle ring, and the sidewall on middle ring top is provided with and loses heart 11; Can see the situation that inner cap 6, cover ring seat 8, enclosing cover 11 are assembled together by Fig. 3, by the former disappointing place connecting duct 13 of inner cap, conduit is provided with cylinder valve pocket 18, dress rotary valve 12 in the valve pocket, and handle 14 is connected with valve body; Fig. 4 has showed the detail structure of gas bleeder valve, and cylinder valve pocket 18 is arranged on the conduit 13, and the cylinder valve body 12 that has guide hole 19 is housed in the cover, and valve body links to each other with handle 14, and valve body is provided with groove 17, pack in the groove packing ring 16 so that valve body be stuck within the valve pocket 18.For the form that adapts to this tank lid and table shape with the facility on making, can adopt thinner metal bar to make the V-arrangement handle, be provided with pin-and-hole at the valve body two ends, the V-arrangement handle is inserted among the pin-and-hole.
