Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model aims at providing a take filter of pressure differential instruction to solve the problem that prior art exists, make the structure of filter succinct more, carry easily, the installation of being convenient for.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
This embodiment provides a take filter of pressure differential instruction, including body 1 and pressure differential table 5, body 1 has inlet, liquid outlet, and the intercommunication is provided with feed liquor chamber 2, filter chamber 3 and play liquid chamber 4 between inlet and the liquid outlet in proper order, still is provided with on the body 1 to be used for pressure differential table 5 to imbed the inside opening of body 1, and the inlet pressure detection mouth of pressure differential table 5, play liquid pressure detection mouth are just right with feed liquor chamber 2 and play liquid chamber 4 respectively.
When the liquid pressure difference meter is used, fluid flows into the liquid inlet cavity 2 from the liquid inlet, then enters the liquid outlet cavity 4 after being filtered by the filter cavity 3 and finally flows out of the liquid outlet, the pressure difference meter 5 can detect the liquid pressure difference in the liquid inlet cavity 2 and the liquid outlet cavity 4 in real time through the liquid inlet pressure detection port, the liquid outlet pressure detection port and the internal detection module thereof, and when the liquid pressure difference in the liquid inlet cavity 2 and the liquid outlet cavity 4 exceeds a set value, the pressure drop of the fluid in the filter cavity 3 is overlarge, so that the filter cavity 3 needs to be cleaned. From this, this embodiment is through embedding differential pressure table 5 in body 1, has replaced the mode that utilizes two root canal to connect feed liquor chamber 2, play liquid chamber 4 among the prior art for the structure of filter is succinct more, carries easily, the installation of being convenient for.
Further, the liquid inlet pressure detection port is parallel to the axis of the liquid inlet cavity 2, and the liquid outlet pressure detection port is parallel to the axis of the liquid outlet cavity 4 in this embodiment.
In order to simplify the structural arrangement of the body 1, the pressure difference meter 5 is located above the filter cavity 3 in the embodiment, and in order to ensure the sealing performance between the pressure difference meter 5 and the body 1, a first sealing ring is further arranged between the pressure difference meter 5 and the opening in the embodiment, so that water leakage at the position of the opening is avoided; it should be noted that, after the differential pressure gauge 5 is embedded into the body 1, because the shape of the differential pressure gauge 5 is different from the shape of the inner cavity of the body 1, it is necessary to ensure the sealing performance between the differential pressure gauge 5 and the body 1, and it is also necessary to ensure that the liquid inlet cavity 2 and the liquid outlet cavity 4 cannot be directly communicated with each other, specifically, the inner wall of the body 1 may be provided with a plugging structure, so as to prevent the fluid from directly flowing into the liquid outlet cavity 4 from the gap between the differential pressure gauge 5 and the inner wall of the body 1 in the liquid inlet cavity 2, and ensure that the liquid inlet cavity 2 and the liquid outlet cavity 4 must be communicated with each other through the filter cavity 3. The specific blocking structure can be set by a person skilled in the art according to the shape of the body 1, and this embodiment will not be described in detail.
Specifically, have pressure difference pilot lamp 7 in this embodiment on the pressure difference table 5, can show green light in the pressure difference settlement range, when feed liquor chamber 2, play liquid chamber 4 pressure difference surpassed the settlement range, show red light warning staff and carry out the clearance of filter chamber 3. It should be noted that, the differential pressure gauge 5 in the present embodiment may adopt an existing device; the arrangement of the detection module in the pressure difference meter 5 and the connection of the pressure difference meter 5 with the pressure difference indicator light 7 are also well known in the art, and therefore, the detailed description thereof is omitted.
