Description
Technical field
The present invention relates to the valve for using at low ambient temperatures.
Background technology
For many years, sewage treatment plant is when temperature is too low in the winter time, there is cryocoagulation, or even freezing pipeline and part in pipeline now, as circulating liquid is freezed so that valve cannot be switched in pipeline, the antifreeze method for using at present is to wrap up, wind frost-resistant material mostly, not only troublesome but also laborious, effect is again not ideal, or even in the case where there is no preferably simple and easy to do antifreezing measures, many worthless methods such as people just pour boiling water on, naked light is roasting, without more comprehensively effectively safe antifreeze measure.
Pure water refers to H2O free from foreign meter, as without cation and anion, so which will not occur chemical reaction with other media, its electrical conductivity is too low to be negligible.
The content of the invention
In order to improve the deficiency that existing sewage valve can not be antifreeze, the present invention provides a kind of simple structure, the good sewage special valve of antifreeze ability.
The technical solution adopted for the present invention to solve the technical problems is：The valve body of sewage special valve is divided into inner valve body and outer valve, frost retarding layer is provided between the inner valve body and outer valve, pure water is provided with the frost retarding layer, the valve body is provided with a temperature controller, the temperature controller is connected with heating head and temperature sensing head, the heating head and temperature sensing head are arranged in frost retarding layer, valve element is provided with inside the inner valve body, passage is provided with the middle of the valve element, the valve element is provided with lower end fixed valve base with the lower contact position of inner valve body, upper end fixed valve base is provided with above the valve element, the cylindrical hole by valve rod is provided with the upper end fixed valve base, the valve rod is connected with valve element, the latch segment coordinated with inner valve body is provided with above the upper end fixed valve base, rubber blanket is provided between the latch segment and upper end fixed valve base, the valve rod upper end is provided with spanner.
A kind of prioritization scheme of such scheme is：The latch segment passes through screw thread or bolt connection with valve body.
Valve element inside inner valve body is rotated by spanner, valve element is fitted close with lower end fixed valve base and upper end fixed valve base, will not leak, upper end fixed valve base is compressed by latch segment, pure water in frost retarding layer does not contain positive and negative ion due to which, so which will not occur chemical reaction with valve body, when the pure water temperature that the temperature sensing head in frost retarding layer is detected in frost retarding layer is less than design temperature, temperature controller control heating head is heated to pure water, and temperature is transferred to the liquid for wherein circulating by inner valve body for the pure water of heating.
The invention has the beneficial effects as follows：The present invention is easy to maintenance, and sealing is high, and resistance to frost is good.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
