Description
Technical field
The present invention relates to a kind of gate valve with environmentally friendly filtering function.
Background technology
When traditional valve installs filter, be typically mounted on the entrance point of valve, it is necessary to specially design one it is additional
Filtration, angie type y-type filter is arranged on the positions of 90 ° of pipeline turn, and the y-type filter structure is relative complex, volume compared with
Greatly, it is relatively costly, because filter is movable, more convenient, easy neglected loading is dismounted, when safeguarding, debris are possible to directly skip
Filter flows into valve.
The content of the invention
The present invention is not enough according to more than, there is provided a kind of gate valve with environmentally friendly filtering function.
The technical scheme is that：
A kind of gate valve with environmentally friendly filtering function, including：
Valve body；
Import valve seat, at the import of valve body；
Outlet valve seat, installed in the exit of valve body；
Valve plate, can move up and down so as to close or open import valve seat and outlet valve seat；
Valve rod, can move up and down, and drive valve plate to move up and down；
Screen pack is installed on import valve seat.
The screen pack is set directly in gate valve, and the size of gate valve is not increased, takes full advantage of the space structure of gate valve, by
Import is relativelyed close in screen pack, the debris of filter screen filtration are also easier to take out.
In order to easy for installation, the excircle of the import valve seat has the first external screw thread, and correspondingly, valve body has supporting
First internal thread, the inner periphery of import valve seat has some first breach, and described screen pack is placed on the end face of import valve seat
And the nose circle face of valve body between, when the first external screw thread of import valve seat is screwed into the first internal thread of valve body, screen pack is compacted
It is fixed, there is the first breach, convenient to install import valve seat using instrument, screen pack can be fixed on import valve seat in modes such as spot welding
On.
In order to increase reliability, the excircle of the screen pack is fixed with bracing ring.There are bracing ring, the rigidity of screen pack
Can greatly increase.
Further, there is the indent of the insertion bracing ring on the end face of the import valve seat.
Used as another technical scheme, the inlet valve seat tool has internal round chamber, the first external screw thread, and internal round chamber also has in second
Screw thread, correspondingly, valve body has first internal thread supporting with the external screw thread of import valve seat first, also including trim ring, trim ring tool
There are the second external screw thread and some second breach, the screen pack is placed on internal round chamber, and second is screwed into by the second external screw thread of trim ring
Internal thread is compressed.
Similarly, the excircle of the screen pack is fixed with bracing ring.
Similarly, there is the indent of the insertion bracing ring on the end face of the trim ring.
The present invention has simple structure, low cost, duct pressure loss is small, circulation is quick, residue-discharge convenience beneficial effect.
Brief description of the drawings
Fig. 1 is overall structure sectional view of the invention.
Fig. 2 is one of mounting structure of screen pack of the present invention.
Fig. 3 is the two of the mounting structure of screen pack of the present invention.
Specific embodiment
In conjunction with accompanying drawing, the present invention is further illustrated：
As illustrated, valve body 1；
Import valve seat 2, at the import of valve body 1；
Outlet valve seat 5, installed in the exit of valve body 1；
Valve plate 4, can move up and down so as to close or open import valve seat 2 and outlet valve seat 5；
Valve rod 3, can move up and down, and drive valve plate 4 to move up and down；
Screen pack 6 is installed on import valve seat 2.
One of further embodiment, the excircle of import valve seat 2 has the first external screw thread 21, and correspondingly, valve body 1 has
The first supporting internal thread, the inner periphery of import valve seat 2 has some first breach 22, and screen pack 6 is placed on import valve seat 2
Between end face and the nose circle face 11 of valve body 1, when the first external screw thread 21 of import valve seat 2 is screwed into the first internal thread of valve body 1, mistake
Filter screen 6 is secured in a press.
The excircle of screen pack 6 is fixed with bracing ring 61.
There is the indent of the insertion bracing ring 61 on the end face of import valve seat 2.
The two of further embodiment, import valve seat 2 has internal round chamber, the first external screw thread 21, and internal round chamber also has second
Internal thread, correspondingly, valve body 1 has first internal thread supporting with the external screw thread 21 of import valve seat 2 first, also including trim ring 7, should
Trim ring 7 has the second external screw thread and some second breach 71, and screen pack 6 is placed on internal round chamber, is twisted by the second external screw thread of trim ring 7
Enter the second internal thread compression.
The excircle of screen pack 6 is fixed with bracing ring 61.
