Description

Be used for the automatic turnover scavenging air valve on the liquid seal container

(1) technical field:

The utility model relates to the turnover device of air; Be specifically related to a kind of automatic turnover scavenging air valve that is used on the liquid seal container.

(2) background technique:

Liquid seal container of the prior art, as splendid attire tank body vinous, when treating that tank inner chamber needs splendid attire or discharging wine liquid, all need manually climb up the manually opened turnover scavenging air valve in tank body upper end, make it to enter in time that its inner chamber is the unnecessary air discharge of wine liquid of tank body, help the splendid attire of wine liquid; Otherwise tank inner chamber easily forms vacuum because of air pressure reduces when outwards putting wine liquid, also needs ambient air in time to enter tank inner chamber and replenishes the smooth discharging that is beneficial to wine liquid.After treating wine liquid splendid attire or racking up, also need manually climb up once more the tank deck throttle down, the operator had both increased labor intensity to the tall and big upper and lower ascend operation in tank body top, had reduced working efficiency again.

(3) summary of the invention:

At the deficiency that above-mentioned prior art exists, the purpose of this utility model be to provide a kind of alleviate labor strength and increase work efficiency be used for automatic turnover scavenging air valve on the liquid seal container.

For achieving the above object, the utility model is used for the automatic turnover scavenging air valve on the liquid seal container, mainly comprises valve body and valve gap; It is to be connected with valve gap in described valve body upper end; Be fixed with guide rod on the described valve gap; The lower spring that described guide rod lower loop cover is connected with links to each other with the lower valve end face that slip is connected on the guide rod; Described lower valve cylindrical places in the body cavity air inlet/outlet and to be gap-like corresponding with its bore area, and described lower valve other end is by the supporting of lower spring, is in same plan-position with the air inlet/outlet end face of body cavity; Slip is connected in the last valve block end face on the guide rod, joins with valve body air inlet/outlet end face and lower valve other end respectively; The described valve block end face of going up is provided with air hole, and upper spring one end and last valve block end face that ring set is connected in the guide rod upper end join, and its other end links to each other with the valve gap interior edge face; Described valve body upper end portion is provided with air inlet/outlet and is communicated with the air inlet/outlet of its inner chamber.

The utility model is taked said structure, by utilizing ring set to be connected in the elastic force supporting of the upper and lower spring of guide rod, make the upper and lower valve block that is connected on the guide rod that slides be in the airtight equilibrium position of valve body air inlet/outlet, when the turnover of wine liquid makes its inner chamber produce pressure change in the jar, elasticity by upper and lower spring changes, the compression lower valve moves down or promotes simultaneously to move on the upper and lower valve block, can realize the automatic turnover ventilation of tank inner chamber gas.Compare with prior art, reduced operator's labor intensity effectively, improved working efficiency significantly.

(4) description of drawings:

Fig. 1 is a sectional view of the present utility model.

(5) embodiment:

Shown in Figure 1.This automatic turnover scavenging air valve that is used on the liquid seal container mainly comprises valve body and valve gap; Described valve body 7 upper end portions are connected with valve gap 1; Be fixed with guide rod 5 on the described valve gap; The lower spring 6 that described guide rod lower loop cover is connected with links to each other with lower valve 4 end faces that slip is connected on the guide rod 5; Described lower valve cylindrical places in the valve body 7 inner chamber air inlet/outlets and to be gap-like corresponding with its bore area; The supporting of described lower valve 4 other ends by lower spring 6 is in same plan-position with the air inlet/outlet end face of body cavity; Slip is connected in last valve block 3 end faces on the guide rod 5, joins with valve body 7 inner chamber air inlet/outlet end faces and lower valve 4 other ends respectively; Described valve block 3 end faces of going up are provided with air hole; Upper spring 2 one ends and last valve block 3 end faces that ring set is connected in guide rod 5 upper ends join, and its other end links to each other with valve gap 1 interior edge face; Described on being provided with valve body 7 upper end portions of valve block, be provided with air inlet/outlet and be communicated with the air inlet/outlet of its inner chamber.Connect good sealing effect for installing, on the valve body lower end face, be provided with seal groove (shown in Figure 1) usually.During use, the utility model is installed on wine tank body upper end, treat that wine liquid enters tank inner chamber, the air pressure of tank inner chamber increases, acting on pressure on the lower valve 4 promote to go up on the elastic force that valve block 3 overcomes upper spring 2 and moves, when treating to move away on the valve block 3 valve body 7 inner chamber air inlet/outlet end faces (with reference to shown in Figure 1), tank inner chamber gas then discharges by the gap between lower valve 4 cylindricals and the valve body air inlet/outlet, when treating that tank inner chamber pressure reaches certain equilibrium value, under the elastic force effect of upper spring 2, on, lower valve is got back to original original state position automatic-closing valve (shown in Figure 1) again.When wine liquid outwards discharges in the jar, tank inner chamber pressure reduces, the external atmospheric pressure value is during greater than the force value of its inner chamber, acting on the elastic force that external atmospheric pressure on the lower valve 4 overcomes lower spring 6 presses down, lower valve 4 end faces are separated with last valve block 3 end joined to move down, this moment, ambient air then entered tank inner chamber (with reference to shown in Figure 1) by the gap between lower valve 4 cylindricals and the valve body air inlet/outlet, when tank inner chamber gas pressure and ambient pressure reach equilibrium value, lower valve 4 moves under the effect of lower spring 6, returns to original state position automatic-closing valve (shown in Figure 1).

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characteristics that the process creative work just can be associated; can also make some modification and/or improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
