It leaks the safety valve for water heater in portion with clearance sealing structure the invention discloses a kind of, includes portion of leaking in valve, include hole of leaking on valve body；The portion of leaking includes：Seal washer, sealing pair outer tube, sealing pair interior bar, washer, fastening seat, spring, pressure regulation cap, seal receptacle, interior bar sealing ring, rivet, stainless steel substrates and handle；There are through-hole, the water flowed out in through-hole that can be flowed to outside safety valve by the hole of leaking on valve body on sealing pair housing tube wall；Clearance seal between sealing pair outer tube and interior bar：When water pressure inside safety valve body is more than certain pressure threshold, water pressure resistance tension force of spring pushes interior bar axial movement, expose through-hole on housing tube wall, so that the water in safety valve body is flowed out by through-hole via hole of leaking, safety valve plays the role of as water heater water tank pressure release.Clearance seal avoids the permanent deformation, material aging, corrosion-vulnerable and the leakproofness that are generated during safety valve sealing flat shim is used for a long time easily by harmful effects such as impurities in water.
Description
Technical field
The invention belongs to safety valve technical fields, refer to a kind of safety valve for water heater.
Background technology
Safety valve is the important safety guard block of water heater, its main operational principle is when in tap water or water heater
In courage the pressure of water higher than water heater specified water pressure when can drain a kind of protective device of decompression outward automatically.Existing safety valve
The automatic pressure reduction structure of excretion outward is all to compress to seal with valve body of safety valve inner surface boss using sealing flat shim, seals plain cushion
Piece surface forms indent, and after this structure is used for a long time, indent position can not restore, and so that contained spring decrement is become smaller, cause
Safety valve pressure is relatively low, while it is also possible that impurity is liable to stick to concave surface, leads to safety valve escape.Seal plain cushion length of a film
Phase is using also inevitably material aging, corrosion-vulnerable etc. are difficult to the defect overcome.Above all multi-purpose flat shims are close
The adverse consequences generated is sealed, annoyings safety valve manufacturer and users always.Therefore, in view of the above-mentioned problems, it is of the invention
It is proposed a kind of new technical solution.

Rank, spring between interior bar boss rank and pressure regulation cap, pressure regulation cap and sealed socket sleeve on sealing pair interior bar one end and with safety
Valve body is threadedly coupled, and sealing pair interior bar sealing ring is sleeved on sealing pair interior bar one end and is pushed down by seal receptacle, and stainless steel substrates are sleeved on
Sealing pair interior bar one end and cover seal receptacle；Sealing pair interior bar is connect by rivet with handle.
The safety valve for water heater in above-mentioned portion of leaking with clearance sealing structure, the sealing pair outer tube and reeve outer tube
In sealing pair between bar part there are gap, which both can guarantee interior bar free axial fortune in outer tube
It is dynamic, and water can be blocked to flow into through-hole on housing tube wall by gap, the water flowed out in through-hole on housing tube wall can pass through
Hole of leaking on valve body flows to outside safety valve.
Above-mentioned to leak the safety valve for water heater in portion with clearance sealing structure, the water pressure inside the safety valve body is less than
When certain pressure threshold V, spring tension pushes sealing pair interior bar to cover through-hole on sealing pair housing tube wall, plays blocking water
The sealing function of stream；When water pressure inside safety valve body is more than certain pressure threshold V, water pressure resistance tension force of spring pushes
Sealing pair interior bar moves axially, and exposes through-hole on sealing pair housing tube wall, so that the water in safety valve body passes through housing
Through-hole plays the role of via the hole outflow that leaks, safety valve as water heater water tank pressure release on tube wall.
The safety valve for water heater in above-mentioned portion of leaking with clearance sealing structure, the clearance sealing structure that the sealing pair is constituted
Principle can be used in safety valve for water heater Inner and let out portion's structure design, and water flow pressure Inner excessive in valve body is let out into water inlet pipe
Road.
Advantageous effect：Present invention application clearance seal principle designs the portion of leaking of safety valve for water heater, effectively overcomes
Safety valve for water heater used at present be susceptible in the long-term use due to sealing flat shim aging and contaminated etc.
The defects of leak caused by reason and abnormal work.
