Abstract

The utility model relates to a filtering gate valve, which belongs to the technical field of the gate valve. The gate valve comprises a handle, a valve core and a valve body, and is characterized in that a slag removal tube inclined downwards is arranged at the bottom part of the valve body, the tube wall of the slag removal tube in the valve body is an annular filtering screen, and the filtering screen is connected with the inner wall of the valve body; and the utility model has the advantages that since the slag removal tube inclined downwards is connected at the bottom part of the valve body of the filtering gate valve, and the water and the dreg and dirt in other liquid can be filtered to the slag removal tube when flowing through the valve body, therefore, the filtering effect is achieved. The filtering gate valve can be placed at the front end of the water meter, also can be installed at any place of the pipeline, for example, the filtering gate valve is installed at the front end of the water meter, the dirt and the dreg in the water can be filtered in time, the normal use of the water meter is protected, and the service life of the water meter is prolonged.

Description

A kind of filtration gate valve

[technical field]

The utility model relates to a kind of gate valve technical field, especially a kind of filtration gate valve.

[background technique]

As everyone knows, the valve of supplying on the market in the past, as Water stop valve, can only play on-off action by water or other flow of fluid, slag and the dirt that exists in water and other liquid be there is no filtering function, Gong Ying some valve has increased filtering function in the market, has increased filter screen in water outlet place, is used to filter slag and dirt.But the shortcoming of this valve is, after long-time the use, slag or dirt can be deposited on the filter screen, causes water outlet to stop up, and makes water or other liquid slow when mobile, and polluted source once more.

[summary of the invention]

The purpose of this utility model is exactly the above-mentioned shortcoming that solves Water stop valve commonly used, and a kind of filtration gate valve is provided.

Solution of the present utility model is: a kind of modified model filters gate valve, comprises handle, spool, valve body, and the valve body bottom is provided with a downward-sloping slagging-off pipe, and the tube wall that the slagging-off pipe is positioned at valve body is the ring-type filter screen, and this filter screen is connected with valve interior wall.

There is openable end cap the bottom of the bottom slagging-off pipe of described slagging-off pipe.

Described downward-sloping slagging-off pipe and the angle between the water outlet are between 30-60 degree.

The beneficial effects of the utility model:, slag in water and other liquid and dirt can be filled into when flowing through valve body in the slagging-off pipe, thereby reach filtering effect because the valve body of this filtering type gate valve bottom is connected with a downward-sloping slagging-off pipe.This filtering type gate valve can be placed on the water meter front end, also can be installed in any position of pipeline, as is installed in the water meter front end, and in time dirt and the slag in the filtered water protected the normal use of water meter, prolongs the working life of water meter.

[description of drawings]

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a generalized section of the present utility model.

[specific embodiment]

Below in conjunction with the drawings and specific embodiments the utility model is described in detail:

As shown in Figure 1 and Figure 2, the structure that the utility model filters gate valve mainly comprises: handle 13, spool 12, valve body 11, handle 13 links to each other with spool 12, handle with sleeve 13 controllable flows, be provided with downward-sloping a stored slag and the slagging-off pipe 3 of dirt in the bottom of valve body 11, slagging-off pipe 3 tube walls that are positioned at valve body 11 are ring-type filter screen 4, filter screen 4 is connected with the inwall of valve body 11, be provided with openable end cap 5 in slagging-off pipe bottom, between preferred 30-50 degree of slagging-off pipe 3 and gate valve water outlet angle, present embodiment is 45 degree.

The working procedure of model utility filter tap is: as shown in Figure 2, handle with sleeve 13, drive spool 12 motions, water or other liquid flow to valve body 11 by water intake, through slagging-off pipe 3 and filter screen 4 time, filter screen 4 filters slag in water or other liquid and dirt, and the water after the filtration or other liquid flow out from water outlet, and slag that is filtered and dirt are stored in the memotron 3.Handle with sleeve 13 once more, drive spool 12 and close, and water or other liquid stop to flow into, and turn on end cap 5, can remove the slag and the dirt that are retained in the slagging-off pipe 3.This valve is used for water flow and cuts valve, vapour, oil, chemical industry flow and cut valve, also can be used for the pipeline of central air-conditioner.

Claims (3)

1. one kind is filtered gate valve, comprises handle, spool, valve body, it is characterized in that: described valve body bottom is provided with a downward-sloping slagging-off pipe, and the tube wall that the slagging-off pipe is positioned at valve body is the ring-type filter screen, and this filter screen is connected with valve interior wall.

2. a kind of filtration gate valve according to claim 1, it is characterized in that: the bottom of described slagging-off pipe is provided with openable end cap.

3. a kind of filtration gate valve according to claim 1 is characterized in that: described downward-sloping slagging-off pipe and the angle between the water outlet are 30-50 degree.
