Abstract

The utility model discloses a gate valve with environmental protection filtering capability, include: a valve body. Inlet valve seat installs the import department at the valve body, the exit at the valve body is installed to the export disk seat, the valve plate, thus can reciprocate close or open inlet valve seat with the export disk seat, the valve rod can reciprocate to the drive valve plate reciprocates, the last filter screen of installing of inlet valve seat. Inlet valve seat's outer circumference has first external screw thread, and correspondingly, the valve body has supporting first internal thread, and inlet valve seat's interior circumference has a plurality of first breachs, and the filter screen is placed between the nose circle face of inlet valve seat's terminal surface and valve body, and when the first internal thread of valve body was twisted by inlet valve seat's first external screw thread, the filter screen was compressed tightly fixedly. The outer circumference of filter screen is fixed with the bracing ring. The utility model has the advantages of simple structure, the loss of with low costs, pipeline pressure is little, the circulation is quick, arrange the convenient beneficial effect of sediment.

Description

There is the gate valve of environmental protection filtering function

Technical field

The utility model relates to a kind of gate valve with environmental protection filtering function.

Background technique

During traditional valve installation filter, usually be arranged on the entrance point of valve, need the filtration that specialized designs one is additional, angie type y-type filter is arranged on pipeline 90 ° of positions of turning round, this y-type filter structure relative complex, volume is comparatively large, and cost is higher, because filter is movable, dismounting is more convenient, easy neglected loading, when safeguarding, foreign material likely directly skip filter flow valve.

Model utility content

The utility model, according to above not enough, provides a kind of gate valve with environmental protection filtering function.

The technical solution of the utility model is:

There is a gate valve for environmental protection filtering function, comprising:

Valve body;

Import valve seat, is arranged on the inlet of valve body;

Outlet valve seat, is arranged on the outlet port of valve body;

Valve plate, can move up and down thus close or open import valve seat and outlet valve seat;

Valve rod, can move up and down, and drives valve plate to move up and down;

Import valve seat is provided with filter screen.

This filter screen is set directly in gate valve, does not increase the size of gate valve, takes full advantage of the spatial structure of gate valve, and because filter screen is relatively near import, the foreign material of filter screen filtration also take out than being easier to.

In order to easy for installation, the excircle of described import valve seat has the first outside thread, correspondingly, valve body has the first supporting internal thread, the inner circumference of import valve seat has some first breach, described filter screen is placed between the end face of import valve seat and the nose circle face of valve body, when the first outside thread of import valve seat is screwed into the first internal thread of valve body, filter screen is secured in a press, there is the first breach, conveniently utilize instrument to install import valve seat, filter screen can the mode such as spot welding be fixed on import valve seat.

In order to increase reliability, the excircle of described filter screen is fixed with bracing ring.Had bracing ring, the rigidity of filter screen can increase greatly.

Further, the end face of described import valve seat has the indent embedding described bracing ring.

As another technological scheme, described import valve seat has internal round chamber, the first outside thread, internal round chamber also has the second internal thread, correspondingly, valve body has first internal thread supporting with import valve seat first outside thread, also comprises trim ring, and this trim ring has the second outside thread and some second breach, described filter screen is placed on internal round chamber, is screwed into the second internal thread compresses by the second outside thread of trim ring.

In like manner, the excircle of described filter screen is fixed with bracing ring.

In like manner, the end face of described trim ring has the indent embedding described bracing ring.

The utility model has that structure is simple, cost is low, duct pressure loss is little, circulation is quick, the beneficial effect of residue-discharge convenience.

Accompanying drawing explanation

Fig. 1 is overall structure sectional view of the present utility model.

Fig. 2 is one of mounting structure of the utility model filter screen.

Fig. 3 is the mounting structure two of the utility model filter screen.

Embodiment

Now by reference to the accompanying drawings the utility model is further described:

As shown in the figure, valve body 1;

Import valve seat 2, is arranged on the inlet of valve body 1;

Outlet valve seat 5, is arranged on the outlet port of valve body 1;

Valve plate 4, can move up and down thus close or open import valve seat 2 and outlet valve seat 5;

Valve rod 3, can move up and down, and drives valve plate 4 to move up and down;

Import valve seat 2 is provided with filter screen 6.

One of further embodiment, the excircle of import valve seat 2 has the first outside thread 21, correspondingly, valve body 1 has the first supporting internal thread, the inner circumference of import valve seat 2 has some first breach 22, filter screen 6 is placed between the end face of import valve seat 2 and the nose circle face 11 of valve body 1, and when the first outside thread 21 of import valve seat 2 is screwed into the first internal thread of valve body 1, filter screen 6 is secured in a press.

The excircle of filter screen 6 is fixed with bracing ring 61.

The end face of import valve seat 2 has the indent embedding described bracing ring 61.

Further embodiment two, import valve seat 2 has internal round chamber, the first outside thread 21, internal round chamber also has the second internal thread, correspondingly, valve body 1 has first internal thread supporting with import valve seat 2 first outside thread 21, also comprises trim ring 7, and this trim ring 7 has the second outside thread and some second breach 71, filter screen 6 is placed on internal round chamber, is screwed into the second internal thread compresses by the second outside thread of trim ring 7.

The excircle of filter screen 6 is fixed with bracing ring 61.

The end face of trim ring 7 has the indent of embedding bracing ring (61).
