Description

Air stop valve for fire control

Technical Field

The utility model relates to a fire control ends pneumatic valve technical field, specificly relates to a fire control is with ending pneumatic valve.

Background

Fire control unit and stage property are used everywhere in life, along with epoch development and technological progress, all kinds of fire-fighting apparatus are progressively perfect, but a lot of fire-fighting apparatus still exist not enoughly, the period that the gas check valve is installed on gas transmission pipeline, the gas check valve mainly plays the effect of opening the transport medium and closing the separation medium, under the operating condition, the switch closure state of valve has decided the quality of valve, current gas check valve is in the use, because the transport medium contains all kinds of impurity, often can influence the work efficiency of valve, the damage of valve accelerates.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a fire control is with ending pneumatic valve can effectively solve the problem that impurity influences work efficiency and valve damage with higher speed in the valve.

The utility model provides a following technical scheme:

the utility model provides a fire control is with ending air valve, includes the valve body, the both ends of valve body are equipped with the ring flange, the top of valve body is equipped with the twist grip, the valve body is located one side pipeline of import and is equipped with the filter screen.

Preferably, the filter screen is obliquely arranged in the pipeline in a direction away from the valve body.

Further preferably, the pipeline is located below the filter screen and is provided with an opening extending downwards, and a collecting cavity detachably connected with the opening is arranged below the filter screen.

Further preferably, the outer wall of the collection chamber and the opening are provided with matching threads.

Further preferably, the bottom of the collection cavity is a sealing cover, and the sealing cover and the collection cavity are of an integrated structure.

Still further preferably, a detachable elastic sealing ring is arranged in front of the sealing cover and the opening.

The utility model discloses possess following beneficial effect:

1. the utility model discloses the stagnant gas valve has set up the filter screen in valve import department, and before the pipeline transport medium through the stagnant gas valve, all kinds of small foreign particles in the transport medium can be blockked by the filter screen, can effectively protect the stagnant gas valve to avoid the foreign particles accumulation to damage the valve, the filter screen that the slope set up when carrying the medium that has certain pressure, can reduce the resistance that the filter screen brought, reduce the influence to conveying efficiency.

2. The utility model discloses the gas check valve has set up the collection chamber, and the detachable collection chamber has been set up to the below of filter screen, can collect the impurity particle that the filter screen blockked off, when waiting that the pipeline is out of work or overhauls, can take out the collection chamber, and reuse after driving impurity has reduced the cost that the gas check valve changed the collection chamber;

3. the utility model discloses the gas check valve collects the chamber and adopts threaded connection between closing to set up elastic sealing circle, threaded connection has better leakproofness for other connected modes such as grafting, and sets up the elastic sealing circle in the bottom, can further strengthen after screwing up the collection chamber and collect the sealing performance between chamber and the valve pipe wall.

Drawings

FIG. 1 is a schematic view of the structure of the air stop valve of the present invention;

in the figure: the valve comprises a valve body 1, a flange plate 2, a rotating handle 3, a filter screen 4, an opening 5, a collecting cavity 6, a sealing cover 7 and an elastic sealing ring 8.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the fire-fighting gas-stop valve comprises a valve body 1, wherein flange plates 2 are arranged at two ends of the valve body 1, a rotating handle 3 is arranged at the top of the valve body 1, and a filter screen 4 is arranged in a pipeline at one side of an inlet of the valve body 1; the filter screen 4 is obliquely arranged in the pipeline in a direction away from the valve body, the obliquely arranged filter screen 4 has a larger filtering area and can block more sundry particles in a conveying medium, and the oblique filter screen 4 has smaller resistance to the conveying medium and smaller influence on the conveying efficiency;

the pipeline is positioned below the filter screen 4, the opening 5 extending downwards is arranged below the filter screen 4, the collecting cavity 6 detachably connected with the opening 5 is arranged below the filter screen 4, sundry particles blocked by the filter screen 4 can fall into the collecting cavity, when the sundry particles in the collecting cavity 6 are excessive, the medium conveying is stopped, the collecting cavity 6 is taken down to remove the sundries, and the sundries can be reused;

the outer wall of the collecting cavity 6 and the opening 5 are provided with matched threads in a threaded connection mode, so that the collecting cavity has good sealing performance, and the phenomenon of leakage between the collecting cavity 6 and the tube wall of the air stop valve is avoided in the medium conveying process;

the bottom of collecting chamber 6 is sealed 7, sealed lid 7 and the structure of collecting chamber 6 as an organic whole, be equipped with detachable elastic sealing ring 8 before sealed lid 7 and opening 5, through the packing of elastic sealing ring 8 between sealed lid 7 and the opening 5, strengthen collecting chamber 8 and the 5 degree of adaptability of opening, sealing performance further obtains improving.

The utility model discloses a realize like this: when carrying the medium in the pipeline, the small foreign particles who carries in the medium can be intercepted by filter screen 4 before reaching the air stop valve, and along with the impurity of interception becomes many, impurity can fall into and collect chamber 6 in to guarantee the transport efficiency of pipeline, and can effectively reduce the damage of impurity to the valve, improve the life of valve, treat that the pipeline overhauls or the pipeline is in idle state, the rotatory chamber 6 of collecting that takes out, and wash impurity, can reuse.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
