Abstract
The utility model relates to a gravity gas return valve used for a pressure container. The gravity gas return valve is formed by that a valve seat (6) is fixed to the wall (2) of the pressure container by a valve cover (1), a valve core is arranged inside the valve seat, and a through hole (5) which is connected with an inner cavity and the interior of the container is opened on the valve seat; the end of the through hole is provided with an elastic cushion (4) and a valve sleeve (3), and the central position of the elastic cushion is provided with a blocking ear of which the major semi-circle is disconnected with the elastic cushion. The utility model has the advantages of gas return, seal, good safety performance, simple structure and low cost.
Description
The utility model relates to pressurized container gravity return-air valve.
The safety exhaust that is used for the seal-off pressure container at present is generally weight valve, pressure fixing valve or other device, but container of again can generation person pressing for existing pressure such as pressure kettle etc., pulling up weight valve after will cooling off by the time just can use, and some inconvenience is provided with movable weight valve, the container of pressure fixing valve device, the soy milk making device that uses as food or family, get liquid machine etc., get liquid after should airtight heating getting liquid or cooling again, make and produce negative pressure in the seal container, thereby gas-returning devices to be arranged, but generally be to establish a return-air valve in addition, increased cost and complexity is installed.
The purpose of this utility model is to provide a kind of exactly can eliminate above-mentioned shortcoming, has the gravity return-air valve of return-air, airtight and safety effect.
Spool (7) is arranged in the valve seat of this device (6), also be provided with a through hole (5) that links with valve base cavity on the valve seat, the through hole end is provided with cushion (4) and valve pocket (3).
The spool of this device (7) top is " ten " word fancy, outer rim contacts with the internal chamber wall of valve seat (6), the spool bottom is a cylindrical body, cone is processed in the cylindrical body end, cone is stuck in inner chamber and the hole that internal tank communicates, and cushion (4) central position has the blocked ear that a greater part of circle and cushion are thrown off, and its diameter is greater than the diameter of through hole (5), valve seat (6) is fixed on the container wall (2) by valve gap (1), the through hole that has several to communicate with atmosphere and valve base cavity on the valve gap.
The utility model volume is little, cost is low, easy to install and use, have return-air, sealing and the multiple function of safety.
Be described further below in conjunction with accompanying drawing:
Description of drawings: figure is the device sectional view.
Comprise valve gap (1), container wall (2), valve pocket (3), cushion (4), through hole (5), valve seat (6), spool (7) among the figure.Valve seat (6) is fixed on the seal-off pressure container wall (2) by valve gap (1), there are several through holes to communicate on the valve gap with the inner chamber of valve seat, the inner chamber of valve seat is equipped with spool (7), the spool bottom is the cylindrical body of diameter less than intracavity diameter, taper is processed in its end, be stuck in inner chamber and the hole that internal tank communicates, spool top is " ten " word fancy, outer rim contacts with internal chamber wall, spool is moved up and down along inner chamber, and make the cone of bottom be stuck in the hole exactly, make inner chamber keep the one state again, the air inlet smoothness of giving vent to anger, the through hole (5) that valve seat (6) also has an inner chamber to communicate with internal tank is provided with valve pocket (3) and cushion (4) in its end, the cushion middle part has the blocked ear of more than half circle and cushion disengagement, its slightly larger in diameter is in the diameter of through hole (5), and a through hole that is slightly larger than the blocked ear diameter is also arranged on the valve gap (3).
One has pressure in this device pressurized container, and cushion (4) promptly seals through hole (5) passage, and when pressure was higher than spool gravity, high pressure backed down spool (7), and gas enters inner chamber by the through hole of valve seat (6), enters atmosphere by the through hole on the valve gap (1) again.After pressure reduced, spool is returning position again, and when pressure was brought down below atmospheric pressure, cushion (4) was inwardly inhaled and opened, and atmosphere is entered in the pressurized container by the inner chamber and the through hole (5) in the through hole seat valve footpath of valve gap (1).
This apparatus structure is simple, installs easily, and is applied widely, is suitable for various pressurized containers.
Claims (4)
1, a kind of gravity return-air valve has valve gap (1), valve seat (6), and it is characterized in that has spool (7) in the valve seat (6), and valve seat is provided with the through hole (5) of a connection inner chamber and internal tank, and the through hole end is provided with cushion (4) and valve pocket (3).
2, gravity return-air valve according to claim 1, it is characterized in that said spool (7) top is " ten " word fancy, outer rim contacts with the internal chamber wall of valve seat (6), and the spool bottom is a cylindrical body, its end is a cone, in the hole that cone is stuck in internal tank communicates.
3, gravity return-air valve according to claim 1 is characterized in that said valve seat (6) is fixed on the container wall (2) by valve gap (1), the through hole that has several to communicate with atmosphere and valve base cavity on the valve gap.
4, gravity return-air valve according to claim 1 is characterized in that said cushion (4) central position has the blocked ear of a greater part of circle and cushion disengagement, and its diameter is greater than through hole (5).
