Abstract
The invention discloses a temperature control valve comprising a valve body which is a three-way valve body. A valve element, a pressure-keeping oil cavity and a valve element adjusting sleeve are arranged in the three-way valve body. Three ends of the three-way valve body are an inlet end, an outlet end and a fire protection spray nozzle connecting end. When the temperature control valve is in a closed state, one end of the valve element abuts against the valve element adjusting sleeve on the inner side of the inlet end, the other end of the valve element and an inner cavity of the valve body form the pressure-keeping oil cavity, and the middle section of the valve element blocks an outlet channel.
Description
Technical field
The present invention relates to a kind of fire-fighting heat-operated valve, specifically a kind of heat-operated valve.
Background technique
In the time of breaking out of fire, existing applicator, cannot directly connect fire-prevention pipe, and the water yield of ejection is limited, in the time there is the large intensity of a fire, easily produces the delay of fire extinguishing.
Summary of the invention
The object of the invention is to design a kind of heat-operated valve.
What the present invention will solve is in the time of breaking out of fire, and existing applicator cannot directly be connected fire-prevention pipe, and the water yield of ejection is limited, in the time there is the large intensity of a fire, easily produces the problem of the delay of fire extinguishing.
Technological scheme of the present invention is: the present invention includes valve body, described valve body is
Three way valve, is provided with spool, pressurize oil pocket, spool adjustment sleeve in three way valve, three ends of three way valve are respectively entrance point, outlet end and applicator connecting end; Under this heat-operated valve closed condition, spool one end withstands on the spool adjustment sleeve of being located at entrance point inner side, and the spool the other end forms pressurize oil pocket with body cavity, and outlet passage is blocked in the stage casing of spool.
Advantage of the present invention is: under temperature is elevated to certain condition, automatically effectively open valve, connect fire water, effectively put out a fire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present invention includes valve body 2, described valve body 2 is three way valve.In three way valve, be provided with spool 6, pressurize oil pocket 3, spool adjustment sleeve 1.Three ends of three way valve are respectively entrance point 11, outlet end 8 and applicator connecting end 5.Under this heat-operated valve closed condition, spool 6 one end withstand on the spool adjustment sleeve 1 of being located at entrance point inner side, and spool 6 the other ends form pressurize oil pocket 3 with body cavity, and outlet passage 9 is blocked in spool 6 stage casings.
Described spool 6 two end outer rings are overlapped respectively to have and are prevented that the O RunddichtringO 7 leaking from appearring in spool
With O RunddichtringO 10.To prevent that leaking from appearring in spool.
At ordinary times, the import termination fire water intake pipe of valve body 2, the outlet end 8 of valve body 2 connects fire-service branch, and applicator connecting end is connected with applicator 4.In the time of breaking out of fire, applicator 4 is broken because of high temperature, the interior decompression of pressurize oil pocket 3, original and spool entrance point 11 hydraulic pressure pressurize oil pocket 3 oil pressure balances are just greater than the oil pressure in pressurize oil pocket 3, and two ends produce pressure differences, this pressure difference impels spool 6 to move to pressurize oil pocket 3, along with spool 6 is to the movement of pressurize oil pocket 3, outlet passage 9 is left in the stage casing of spool 6, and finally moves to spool 6 and leave outlet passage 9, and entrance point 11 and outlet end 8 are connected, fire water sprays automatically from outlet end.
Claims (3)
1. a heat-operated valve, comprises valve body, it is characterized in that described valve body is three way valve, is provided with spool, pressurize oil pocket, spool adjustment sleeve in three way valve, and three ends of three way valve are respectively entrance point, outlet end and applicator connecting end; Under this heat-operated valve closed condition, spool one end withstands on the spool adjustment sleeve of being located at entrance point inner side, and the spool the other end forms pressurize oil pocket with body cavity, and outlet passage is blocked in the stage casing of spool.
2. heat-operated valve according to claim 1, the spool two end outer rings described in it is characterized in that are overlapped respectively to have and are prevented that the O RunddichtringO leaking from appearring in spool.
3. heat-operated valve according to claim 1, is characterized in that described applicator connecting end is connected with applicator.
