Abstract
Disclosed is a reversible one-way valve. An existing one-way valve is capable of ensuring liquid to flow towards one direction and stopping the liquid from flowing towards the other direction; once process flow requires changing the existing one-way valve into a circulation pipeline, changing liquid directions can not be realized; and a conventional gravity one-way valve with small sealing force is not suitable for high-pressure occasion. The reversible one-way valve comprises a valve body (2); two ends of the valve body are connected to a connecting pipe (1) and a connecting pipe (5) along axial direction; a rotary shaft box is mounted on the upper portion of the valve body along vertical direction; one end of a rotary shaft (8) of the rotary shaft box is positioned outside the valve body; a boss (3) and a locking hole (6) are arranged at the end of the rotary shaft (8); the other end of the rotary shaft (8) is positioned inside the valve body and hinged with a valve plate; and the valve plate is hanged and fastened onto a connecting pipe orifice when in one-way work. The reversible one-way valve serves as a one-way valve capable of circulating bidirectionally.
Description
Technical field:
The utility model relates to a kind of valve, is specifically related to a kind of unidirectional and one-way valve that two-way circulate can selected.
Background technique:
Existing one-way valve can guarantee that liquid flows towards a direction, another direction does not allow to flow, in case technological process requires to become circulation duct, change liquid flow direction and just can't realize, existing one-way valve can guarantee that liquid flows towards a direction, and another direction does not allow to flow, in case technological process requires to become circulation duct, change liquid flow direction and just can't realize that traditional gravity one-way valve sealing force is little, be not suitable for kind of high pressure position and close.
Summary of the invention:
The purpose of this utility model provides a kind of reversible one-way valve, can change the flow direction of liquid as required.
Above-mentioned purpose realizes by following technological scheme:
Reversible one-way valve, its composition comprises: valve body, described valve body two ends connect adapter vertically, the rotating shaft case is installed in the top of described valve body vertical, rotating shaft one end in the described rotating shaft case is positioned at the valve body outside and has boss and position and lock hole, the other end of described rotating shaft is positioned at valve inner and valve plate is hinged, hangs down during described valve plate one-way only operation to be buckled in and takes over mouthful.
Described reversible one-way valve, the angle of swing of described locking aperture are 0-90 °, and described valve plate is the Z type.
The beneficial effects of the utility model:
1. when the utility model was made one-way valve and used, valve plate was sagging around the shaft, cover by weight and take over mouthful, when the pressure in the mouth of pipe greater than the outside pressure situation under, one-way valve is opened, and realizes that direction of liquid is mobile.When the tool using rotating boss and when locking locking aperture, valve plate rotates the N degree simultaneously, and valve plate leaves sealing orifice, and all open on the valve two sides, and liquid can two-way flow, has realized a valve purpose double-duty.
2. the utility model has effectively avoided using the one-way valve pipeline to change the process route that flow direction must install bypass additional, and it is efficient to have improved the making of valve.Because the rotating shaft case improves rotating shaft position in vertical, valve plate upwards strengthens, and weight increases, and has strengthened sealing effect, can more extensively promote the use of.
Description of drawings:
Accompanying drawing 2 is the utility model using process schematic representation.
Embodiment:
Embodiment 1:
Reversible one-way valve, its composition comprises: valve body 2, described valve body two ends connect adapter 1 vertically and take over 5, the rotating shaft case is installed in the top of described valve body vertical, rotating shaft 8 one ends in the described rotating shaft case are positioned at the valve body outside and have boss 3 and position and lock hole 6, the other end of described rotating shaft is positioned at valve inner and valve plate 4 is hinged, hangs down during described valve plate one-way only operation to be buckled in and takes over mouthful.
Described reversible one-way valve, the angle of swing of described locking aperture are 0-90 °.
Working principle:
When doing the one-way valve use, valve plate position and adapter axis normal, can realize that direction of liquid flows, when tool using 7 rotating boss, 90 degree and locking locking aperture, valve plate revolves simultaneously and turn 90 degrees, and valve plate becomes 90 degree with the adapter axis, and all open on the valve two sides, liquid can two-way flow, has realized a valve purpose double-duty.
Claims (2)
1. reversible one-way valve, its composition comprises: valve body, it is characterized in that: described valve body two ends connect adapter vertically, the rotating shaft case is installed in the top of described valve body vertical, rotating shaft one end in the described rotating shaft case is positioned at the valve body outside and has boss and position and lock hole, the other end of described rotating shaft is positioned at valve inner and valve plate is hinged, hangs down during described valve plate one-way only operation to be buckled in and takes over mouthful.
2. reversible one-way valve according to claim 1 is characterized in that: the angle of swing of described locking aperture is 0-90 °, and described valve plate is the Z type.
