Abstract
A kind of water heater Decompression valves, includes hollow valve body, is suction port in the bottom of described valve body, and described valve body top is threaded connection installs end cap screw; The corresponding suction port of described valve interior wall one end is one-body molded step, on described step, has through hole; In the valve pocket of valve body and end cap screw and step composition, be provided with valve rod, with spool, voltage regulation screw and stage clip that step through-hole is sealed and matched, described voltage regulation screw is positioned at end cap screw below, is threaded with valve interior wall.The utility model is in the time that water tank internal air pressure exceeds standard, and pressure pushing tow spool, overcomes the pressure of stage clip, and pressure or air pressure are discharged by the air outlet on through hole and valve body on step, reaches the effect of release, simple in structure, fabricating cost is low, using effect good.
Description
(1) technical field
The utility model relates to a kind of water heater Decompression valves, is particularly useful on the water tank of solar water heater.
(2) background technique
For safety, need on the water tank of solar water heater, install pressure relief additional, existing pressure relief device complex structure, cost are high, and using effect is general.
(3) summary of the invention
The technical problems to be solved in the utility model is to provide a kind of water heater Decompression valves, simple in structure, with low cost, and using effect is good.
For this reason, the utility model is taked following technological scheme:
A kind of water heater Decompression valves, includes hollow valve body, is suction port in the bottom of described valve body, and described valve body top is threaded connection installs end cap screw; The corresponding suction port of described valve interior wall one end is one-body molded step, on described step, has through hole; In the valve pocket of valve body and end cap screw and step composition, be provided with valve rod, with spool, voltage regulation screw and stage clip that step through-hole is sealed and matched, described voltage regulation screw is positioned at end cap screw below, is threaded with valve interior wall; Described spool is arranged on valve rod tail end, spool size is greater than the through-hole aperture on step, and described valve stem tip runs through described voltage regulation screw, and described voltage regulation screw is provided with described stage clip, stage clip one end and step upper-end surface offset, and the other end and voltage regulation screw lower end surface offset; Side between the corresponding end cap screw of described valve body and step has air outlet; Described end cap screw and voltage regulation screw upper-end surface have straight-line groove.
The screw thread terminal that described valve interior wall coordinates with voltage regulation screw is positioned at the top of air outlet.
The corresponding step of described valve outer wall below is provided with outside thread.
Described step is outward extended with surrounding edge from valve outer wall.
Described surrounding edge external frame is regular hexagon.
The utility model has the advantages that: 1, in the time that water tank internal air pressure exceeds standard, pressure pushing tow spool, overcomes the pressure of stage clip, and pressure or air pressure are discharged by the air outlet on through hole and valve body on step, reach the effect of release, simple in structure, fabricating cost is low, using effect good; 2, in valve body, be provided with voltage regulation screw, can regulate as required the air pressure in valve pocket, wide adaptability; 3, valve body is connected with water tank by the outside thread of step below, simple, convenient.
(4) brief description of the drawings
