Abstract
The utility model discloses a gas water heater safety valve. The gas water heater safety valve comprises a valve body, a valve core, a sealing spring, a pressure adjustment screw and a sealing gasket. A valve core inner hole is formed in the valve core, a water inlet hole is formed in the lateral wall of the valve core inner hole, the pressure adjustment screw is connected with the lower portion of the inner cavity of the valve body in a threaded mode, the upper portion of the sealing spring is arranged in the valve core inner hole, the lower end of the sealing spring makes contact with the pressure adjustment screw, and the sealing gasket is arranged on the top of the valve core. The gas water heater safety valve has the advantages of being conveniently adjustable pressure, good in sealing effect and smooth in drainage, saving copper materials and the like.
Description
Technical field
The utility model relates to a kind of Decompression valves, especially relevant with the gas water-heater Decompression valves.
Background technique
Existing gas water-heater Decompression valves is due to structural reason, more difficult if adjusted the pressure release pressure ratio after assemble, in addition, also exists that sealing effect is bad, draining is difficult, expends the deficiency such as copper material.
Summary of the invention
The purpose of this utility model is to provide a kind of pressure regulation convenience, good sealing effect, draining is unobstructed and the gas water-heater Decompression valves of saving copper material.
For achieving the above object, the utility model is achieved through the following technical solutions.The gas water-heater Decompression valves, comprise valve body, spool, Packing spring, pressure regulating screw and sealing gasket, on spool, have the spool endoporus, at spool endoporus sidewall, have water inlet, pressure regulating screw is connected with the body cavity lower thread, Packing spring top is located in the spool endoporus, and lower end contacts with pressure regulating screw, and sealing gasket is located at the spool top.
Described gas water-heater Decompression valves, be provided with weep hole on adjusting screw.
Described gas water-heater Decompression valves, the material of its valve body are ABS or PPS plastics.
Model utility compared with prior art has the following advantages: (one) is because pressure regulating screw is connected with the body cavity lower thread, and withstands on the Packing spring bottom, can conveniently adjust pressure release pressure; (2) be owing at the spool top, sealing gasket being set, greatly improved the sealability of Decompression valves; (3) be that draining is unobstructed owing on adjusting screw, being provided with weep hole; (4) be in some occasion, the material of valve body can adopt without copper material ABS or PPS plastics, can save copper material.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model gas water-heater Decompression valves.
