Description
Technical field
The utility model relates to valve, particularly relates to a kind of easily installation bilateral switching pressure difference valve.
Background technique
Pressure difference valve and self-balanced differential pressure valve, do not need the external energy, relies on and automatically adjusted by the change of tune medium pressure itself, the flow deviation that the residual pressure head of automatic elimination pipeline and pressure surge cause, constant user inlet outlet pressure differential.Pressure difference valve is specially adapted in household metering or automatic control system, contributes to stable system and runs.But the pressure difference valve on market can not regulate pressure reduction direction.
Model utility content
The purpose of this utility model is that providing a kind of easily installs bilateral switching pressure difference valve, has and can adjust pressure reduction direction feature as required.
In order to achieve the above object, the technological scheme that the utility model provides is: a kind of bilateral switching one-way valve, comprise ball valve body, described valve body is provided with connecting tube, described connecting tube is provided with sleeve pipe nut, described connecting tube offers internal thread, in described ball valve body, spool is installed, described spool is provided with connecting rod, described connecting rod is provided with handle, described spool offers valve hole, in described valve hole, one-way valve is installed, described one-way valve comprises spring, described spring is provided with plug, described plug offers respectively the first plug through hole, second plug through hole and the 3rd plug through hole.
The beneficial effects of the utility model are: the utility model is by comprising ball valve body, described valve body is provided with connecting tube, described connecting tube is provided with sleeve pipe nut, described connecting tube offers internal thread, internal thread can directly be connected with external outside thread, and sleeve pipe nut is convenient to be fixed with spanner when mounted and turns.In described ball valve body, spool is installed, described spool is provided with connecting rod, described connecting rod is provided with handle, described spool offers valve hole, in described valve hole, one-way valve is installed, described one-way valve comprises spring, and described spring is provided with plug, described plug offers respectively the first plug through hole, the second plug through hole and the 3rd plug through hole.By the pressure reduction direction of rotatory handling adjustment differential pressure switch, also by rotatory handling adjustment uninterrupted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model spool.
Embodiment
Embodiment 1
As shown in Figure 1: a kind of easily installation bilateral switching pressure difference valve, comprise ball valve body 1, described valve body 1 is provided with connecting tube 12, described connecting tube 12 is provided with sleeve pipe nut 13, described connecting tube 12 offers internal thread 14, internal thread 14 can directly be connected with external outside thread, and sleeve pipe nut 13 is convenient to be fixed with spanner when mounted and turns.In described ball valve body 1, spool 2 is installed, described spool 2 is provided with connecting rod 3, described connecting rod 3 is provided with handle 4, described spool 2 offers valve hole 5, in described valve hole 5, one-way valve 6 is installed, described one-way valve 6 comprises spring 7, and described spring 7 is provided with plug 8, described plug offers respectively the first plug through hole 9, second plug through hole 10 and the 3rd plug through hole 11.By the pressure reduction direction of rotatory handling adjustment differential pressure switch, also by rotatory handling adjustment uninterrupted.
Described 3rd plug through hole 11 is connected with valve hole 5 and is positioned at same straight line, and described first plug through hole 9 is mutually vertical with the 3rd plug through hole 11, and the first plug through hole 9 and the second plug through hole 10 are positioned at same straight line.Make plug via arrangements more reasonable, thus make the resistance of valve body less.
