Description

Automatic monitoring constant-temperature deluge valve prying block

The technical field is as follows:

the utility model belongs to the technical field of fire control and fluid control, in particular to automatic control constant temperature drenches valve sled piece.

Background art:

at present, control valves used by a water spraying system for fire fighting of devices such as an outdoor tank area in the industries of winter, electric power and the like are mostly located outdoors according to design specifications, are distributed dispersedly and need remote field operation in cold areas in China, areas with outdoor temperature below zero, and the like. When the problem of the dispersed arrangement is solved, the improved structure in recent years adopts the fire-fighting deluge control valve chamber with a centralized brick-concrete structure, and an underground heat-preservation valve well or a valve pipeline is arranged to do simple heat-preservation heat tracing measures on site, but still has a plurality of problems which are difficult to solve:

(1) the fire-fighting deluge control valve chamber for intensively building the brick-concrete structure needs to adopt heating facilities, and needs to intensively introduce all dispersed pipelines into the valve chamber, so that the pipeline laying and laying distance is too long, the fire-fighting time response time from fire-fighting water flowing through the pipeline to a fire-fighting point after the valve is opened is too long, and the fire-fighting regulation cannot be met;

(2) the civil engineering cost is very high, and land resources are wasted;

(3) at large-scale storage tank field, the tank field dispersion, the deluge control valve arranges and needs the dispersion setting, need build more deluge valve rooms, receives the unable construction condition of field effect fire control deluge control valve room, especially in some petrochemical enterprises fire control hidden danger administers the transformation engineering, does not have the land that can be used to construct the deluge valve room at all, all can cause the limitation of concentrating the deluge valve room.

When an underground valve well is arranged, the following problems exist;

(1) in rainy season, the rain water is easily filled fully, so that the equipment is damaged, and a fire-fighting system is paralyzed.

(2) In the petrochemical industry, toxic and harmful gases are easy to accumulate in a well, and personal injury is caused when an operator operates the well.

(3) The use of fire protection codes against which the fire deluge valve should be installed in an easy-to-operate position is currently not allowed.

In order to solve the problems, some construction units and design units provide a simple on-site heat preservation method, and the heat tracing mode adopts hot water, steam, electric heating and other modes, but the following problems also exist:

(1) the deluge control valve is simply wrapped under the cotton and outer protection tube shell of heat preservation, lays wherein with the heating pipe together, and daily operation need open the heat preservation cover, and operation process is too loaded down with trivial details. If a valve on a control pipeline is operated, the index of a control instrument cannot be observed, the relevant law and regulation regulations of fire fighting are violated, and rapid and convenient operation on site cannot be realized, so that fire fighting hidden danger is caused.

(2) Temperature control can not realize accurate control, and the working state of a fire fighting system can not be remotely monitored in a control room. For the temperature control, only extensive control is carried out, overheating and supercooling can be caused by hot water type heat preservation and steam type heat preservation, the temperature of the whole fire-fighting valve is generally 4-80 ℃, the electromagnetic valve and the pressure switch electrical control element are required to be controlled to be about 0-50 ℃, the electrical element is aged due to overhigh temperature, the service life of the control valve is influenced, the fire-fighting freezing problem is caused by supercooling, and the fire-fighting system is stopped in winter by a specific enterprise with the failure of the whole fire-fighting system, so that great fire-fighting hidden danger is caused.

(3) At present, most of heat preservation modes of the deluge valve do not use an automatic temperature control function and a low-temperature alarm function, so that personnel in a control room cannot accurately master the working temperature of the valve, cannot receive an alarm signal and cannot arrive at the site for treatment at the first time. Thereby easily causing fire-fighting hidden trouble.

(4) At present, most of heat preservation modes of the deluge valve cannot meet the convenience of operation, and the problems of convenient operation and daily inspection of the valve cannot be solved at present because each operation process of the control valve needs to be operated in the front and back or up and down of the valve.

(5) Individual design suggestion adopts on-spot simple and easy insulation can, mostly is the temporary setting of construction unit, overhauls the space narrowly, and the chamber door design is unreasonable, is difficult to guarantee the thermal insulation performance from the type selection calculation, and the thermal insulation performance can't be at the accurate test of on-the-spot, and the maintenance of being not convenient for, long-range unable fine control of realizing.

(6) At present, the maintenance valves and connecting pipe sections of the deluge valve, a signal butterfly valve in front of the valve and the like are generally arranged non-uniformly, the problems that pipelines, electric wiring and the like are not arranged according to national standard drawing sets individually, the problem that the valves and the insulation can are organically combined exists, and for the mode that the pipelines penetrate through the insulation can, the gap is too large, and the valves and the connecting pipe sections cannot penetrate through flanges.
