Abstract
The utility model discloses a head face airproof electric water heater safety valve, comprising a valve body, an inner discharging device, a water entering spring, an escaping device, a positioning cap, an O shaped ring and a flat gasket. The O shaped ring covers in the O shaped groove at the lower side of the positioning cap; the upper head face of the positioning cap is provided with the flat gasket; a positioning convex pit is arranged at the connecting position of the valve body main cavity and the positioning cap. The utility model has the advantages of rational structure, convenient mounting, good sealing capacity, safety and reliability, suitable for any type electric water heater.
Description
One, technical field:
The utility model relates to a kind of electric water heater safety valve, and is especially relevant with the end face seal electric water heater safety valve.
Two, background technique
Safety valve is the important composition parts of electric water heater, and its groundwork principle is a kind of protective gear that can drain automatically when tap water pressure is higher than the inner container of electric water heater rated pressure.The safety valve of producing on the existing market is when being threaded with electric water heater, and sealing easily produces and leaks by the sealing of auxiliary seal band; Degree of depth location not when screw thread is screwed into causes to be screwed into too deeply, or is screwed into and overexerts, and the valve body cracking phenomena occurs.
Three, summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, and is easy for installation, safe and reliable end face seal electric water heater safety valve of new generation.
For achieving the above object, the utility model is realized by following technical solution: the end face seal electric water heater safety valve, comprise valve body, interior arranging device, water inlet spring, leakage device, positioning cap, O type circle and flat gasket, O type snare is in the O of positioning cap downside type groove, and flat gasket is equipped with in the positioning cap upper-end surface.
Described end face seal electric water heater safety valve also is provided with the protruding bank in a location with the positioning cap contacting point in the valve body main cavity.
The utility model compared with prior art has the following advantages: (one) installs with electric water heater to be connected with the seal with flat gasket of positioning cap end face, and after the installation, difficult generation is leaked; When (two) being installation, being screwed into the degree of depth has the positioning cap location, thereby solves the valve body cracking phenomena; (3) be when installing on the screw thread without the auxiliary seal band, it is more clear, simple and clear to reduce installment work intensity and the back overall appearance is installed; (4) be on the electric water heater safety valve applicable to any kind.
Four, description of drawings
Fig. 1 is the structural representation of the utility model end face seal electric water heater safety valve.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the end face seal electric water heater safety valve comprises valve body 1, interior arranging device 3, water inlet spring 4, leakage device 5, positioning cap 7, O type circle 8 and flat gasket 6, O type circle 8 is enclosed within the O type groove of positioning cap 7 downsides, and flat gasket 6 is equipped with in positioning cap 7 upper-end surfaces, and interior arranging device 3 is headed on by water inlet spring 4, be contained in valve body 1 main cavity by positioning cap 7 center holes location, in valve body 1 main cavity, also be provided with the protruding bank 2 in a location with positioning cap 7 contacting points.
Claims (2)
1, a kind of end face seal electric water heater safety valve, comprise valve body (1), interior arranging device (3), water inlet spring (4), leakage device (5) and positioning cap (7), it is characterized in that: it also comprises O type circle (8) and flat gasket (6), and O type circle (8) is enclosed within the O type groove of positioning cap (7) downside, and flat gasket (6) is equipped with in positioning cap (7) upper-end surface.
