Abstract
The utility model discloses a one-way valve device for low-pressure steam lines. The one-way valve device for low-pressure steam lines is used for unidirectional breaking and composed of a valve body and a valve cover which is arranged on the inclined plane of the hole opening of the inner opening corresponding to the steam inlet port of the valve body, wherein, the valve cover can be cut off by gravity and pushed away by delivering the steam pressure. The one-way valve device for low-pressure steam lines is mainly used for being matched with a steam vapor cabinet for preventing steam in a bathing cover reflowing into a blower system, and therefore, the damage of a blower and an electric circuit device thereof can be avoided. The utility model is cabinet, practical and simple in structure.
Description
The utility model relates to one-way valve, specifically a kind of one-way cock device that is exclusively used in low pressure steam line.
In existing portable steam vapor cabinet, the high-temperature water vapor that steam generator produces is delivered to steam in the steam-inflated plastic shroud by the pressure conveying of blower and is used for steaming to bathe, hot water was treating stranguria when bath finished shutdown but carries out steaming, damp and hot water vapor in the steam-inflated plastic shroud certainly will reflux by former pipeline and enter blower fan, thereby fan and electric control circuit apparatus thereof bring infringement.
The purpose of this utility model is to propose a kind of Pneumatic unidirectional valve that prevents steam refluence usefulness that is exclusively used in, and it can be controlled at the unidirectional blocking-up of taking over steam passage in the road effectively.
This Pneumatic unidirectional valve, comprise valve body and valve gap, it is characterized in that valve body is provided with two connecting ports, wherein the aperture face of the corresponding internal orifice of the port of front is the inclined-plane, a gravity type valve gap is set on the angle face, valve gap is hinged on the valve body of top, inclined-plane, and the valve pocket that surrounds in the valve body communicates with two connecting ports, and valve gap is positioned at valve pocket.
One-way cock of the present utility model utilizes the cooperation on the gravity and the valve body inner port inclined-plane of its valve gap, reaches the control purpose of unidirectional blocking-up water vapor path effectively, is used among the steam vapor cabinet, can improve the Security and the operating life of bath cabinet blower fan system.
Accompanying drawing has provided specific embodiment.
Fig. 1 is the basic structure schematic representation of Pneumatic unidirectional valve.
Fig. 2 is embodiment's two a structural representation.
Referring to accompanying drawing.Pneumatic unidirectional valve shown in Figure 1, valve body is formed by being threaded by valve seat 1 and tube cover 2, and 7 is seal ring, the middle valve pocket that forms, valve pocket communicates with two connecting ports 5,8 on the valve body, and with the port 8 corresponding internal orifices 6 that are provided with, this internal orifice aperture face 9 is the inclined-plane on the valve seat 1, bevel angle is 10 °-15 °, a gravity type valve gap 4 is set on the angle face, and it is hinged on the valve body of top, inclined-plane, is interrelated by articulated axle 3 and axle ear, valve gap 4 is positioned at valve pocket, and aperture is upwards less than 90 °.The external position at port 5,8 places is made turriform and is connect the mouth form, and keeping the center line of valve seat, port when port 8 is hinged with for forward is substantially horizontal, and the axle ear upwards makes valve gap folding work normally.Embodiment shown in Figure 2, its structure is formed fully identical with Fig. 1 example, but the mode of structure difference of its valve seat port 8, connecing mouth is French Franc dish linkage structure.The water tank wall of being convenient to direct and steam generator like this is correctly fixing, and valve gap at any time can both proper functioning.
The water vapor air-flow enters from the left side during work, pushes valve gap 4 open, sends from the right.After the shutdown of steam generator and blower fan, the steam cutout is dodged and is covered 4 and because of its deadweight internal orifice 6 is closed, and realizes unidirectional blocking-up.
Claims (2)
1, a kind of Pneumatic unidirectional valve, comprise valve body and valve gap (4), it is characterized in that valve body is provided with two connecting ports (5,8), wherein the aperture face of the corresponding internal orifice of the port of front (8) (6) is the inclined-plane, a gravity type valve gap (4) is set on the angle face, valve gap (4) is hinged on the valve body of top, inclined-plane, and the valve pocket that surrounds in the valve body communicates with two connecting ports (5,8), and valve gap (4) is positioned at valve pocket.
2, Pneumatic unidirectional valve as claimed in claim 1 is characterized in that the bevel angle that internal orifice (6) is located is 10 °-15 °.
