Abstract
The invention relates to a novel temperature sensing water flow control valve which is mainly composed of a water inlet channel, a water outlet channel, a valve body, a temperature sensing glass ball and a fixed yoke rod. The interior of the valve body is communicated with the water inlet channel and the water outlet channel. The valve body is divided into a water inlet cavity and a water outlet cavity through a diaphragm. A valve rod and a spring in a stretching state are installed in the water outlet cavity. The spring is arranged on the valve rod in a sleeving mode, one end of the valve rod is connected with the diaphragm, and the other end of the valve rod is connected with one end of the temperature sensing glass ball in the yoke rod. The other end of the temperature sensing glass ball is fixed through a screw on the top of the yoke rod. An upper limiting device and a lower limiting device are arranged in the valve body, and the diaphragm moves between the upper limiting device and the lower limiting device. The height of the temperature sensing glass ball is not smaller than the distance between the limiting devices. The novel temperature sensing water flow control valve is simple in structure and reliable in performance and is mainly used for control over water flow on a water supply pipeline at the tail end of a nozzle of a wet type automatic sprinkler system.
Description
Technical field
The present invention relates to a kind of fire-protection equipment, specifically refer to a kind of temperature-sensitive water flow control valve being arranged on automatic wet pipe sprinkler system shower nozzle end supply channel.
Background technique
Automatic wet pipe sprinkler system mainly comes from spraying head to the protection of building and in fire, breaks timely even with the water distribution of shower nozzle.Due to the complexity of building structure and inside decoration, if while spraying head being arranged on be easy to be subject to the position of fire smoke effect, the water that shower nozzle sprays can be fitted up or pipeline, member etc. block, and affects distribution performance, even occurs the white space that cannot cover; If shower nozzle is arranged on the position that can not affect water distribution, shower nozzle cannot effectively be experienced the temperature of fire, can not move in time, causes the expansion that spreads of the intensity of a fire.The passing through of country's Code for design of automatic fire sprinkler systems regulation adjusted nozzle position and avoids blocking and adding the method for shower nozzle, solved to a certain extent the problems referred to above, but still had many insurmountable difficulties.As to the closeer grid ceiling of density, as by code requirement by shower nozzle be arranged on furred ceiling, under ceiling, the water distribution of shower nozzle can be subject to serious impact, the serious fire extinguishing effect that reduces; As shower nozzle is arranged under furred ceiling, shower nozzle can not move in time, also can affect fire extinguishing effect.
Summary of the invention
The present invention seeks to by designing a kind of control gear, solve shower nozzle in automatic sprinkling system and move in time and be not subject to obstacle to block the problem of effective watering.
The object of the invention is achieved through the following technical solutions:
The present invention is mainly made up of intake tunnel, exhalant canal, valve body, temperature sensing glass ball, tie-down yoke bar, and described valve inner is communicated with intake tunnel, exhalant canal; Valve body is divided into two cavitys of water inlet and outlet by barrier film by valve body, water chamber is provided with valve rod and the spring in extended state, spring is nested with on valve rod, one end of valve rod is connected with barrier film, the other end is connected with the one end that is arranged on the temperature sensing glass ball in yoke bar, and the other end of temperature sensing glass ball is fixed by the screw of yoke masthead portion; In valve body, have upper and lower two limit stoper, barrier film is movable between upper and lower two limit stoper.The height of described temperature sensing glass ball is not less than the distance between limit stoper.
Foregoing invention can effectively solve the problem of in time action of shower nozzle and unaffected watering, has easy for installation, simple in structure, reliable performance, economically viable feature.

Embodiment
Below in conjunction with embodiment, the present invention will be further described:
As depicted in figs. 1 and 2, the present invention is mainly made up of intake tunnel 1, exhalant canal 2, valve body 3, temperature sensing glass ball 7, tie-down yoke bar 8, and described valve inner is communicated with intake tunnel, exhalant canal; Valve body is divided into two cavitys of water inlet and outlet by barrier film 4 by valve body, water chamber is provided with valve rod 5 and the spring in extended state 6, spring is nested with on valve rod, one end of valve rod is connected with barrier film, the other end is connected with the one end that is arranged on the temperature sensing glass ball in yoke bar, and the other end of temperature sensing glass ball is fixed by the screw of yoke masthead portion; In valve body, have upper and lower two limiting stoppers 9,10, barrier film is movable between upper and lower two limiting stoppers.The height of described temperature sensing glass ball is not less than the distance between limit stoper, and described barrier film has good water proof effect, and resistance when mobile in valve body (3) is enough little.
As shown in Figure 3 and Figure 4, the proposition of the invention a kind of temperature-sensitive water flow control valve, this valve intake tunnel water-filling at ordinary times, exhalant canal is anhydrous at ordinary times, exhalant canal is communicated with deluge system by pipeline, temperature-sensitive water flow control valve is arranged on the position that is easy to experience fire hazard thermal effect, and deluge system is arranged on the position that can not affect water distribution characteristic.
The present invention is in work set condition.Water-inlet cavity is full of water, and barrier film 4 is against on lower limit piece 9 under the effect of valve rod 6, temperature sensing glass ball 7 and screw 11, now in water chamber, there is no water.
After fire occurs, temperature sensing glass ball is broken under heat effect, and barrier film, under the Water Pressure of extension spring and water-inlet cavity, moves to upper limit piece, and as shown in Figure 3, now water chamber is full of water, the pipe network water supply fire extinguishing after exhalant canal.
After fire extinguishing finishes, manually the piece that rolls off the production line is got back to in valve rod top, again load onto temperature sensing glass ball, be fixed by screw, the present invention comes back to set condition.
