Abstract
The open one of the utility model can bilateral switching pressure difference valve, comprise ball valve body, 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.
Description
Technical field
The utility model relates to valve, and particularly relating to one can 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 to provide one can 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, 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, is provided with one-way valve in described valve hole, described one-way valve comprises spring, 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.
Described third through-hole is connected with valve hole and is positioned at same straight line, and described first plug through hole is mutually vertical with third through-hole, and the first plug through hole and the second plug through hole are positioned at same straight line.
The beneficial effects of the utility model are: the utility model is by comprising ball valve body, 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, is provided with one-way valve in described valve hole, described one-way valve comprises spring, 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 illustrates:
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: one can bilateral switching pressure difference valve, comprise ball valve body 1, 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 third 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 third 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.
