Abstract
The utility model relates to a filtering safety valve for liquid heating equipment, such as an electric boiler, an electric shower, etc. The safety valve comprises a valve body 1 and a valve core 2 arranged in the valve body 1. The utility model is characterized in that the valve body 1 is a hollow post-shaped body; the outer surface and an inner hole are respectively provided with outer threads 11 and inner threads 12; the end part on the end far from the inner threads is provided with a small hole 13; the inner part of the valve body is provided with the valve core 2, a spring 3 and eye bolts 4 connected with the inner threads 12 in turn; the other end is provided with a filter 5 and a sealing ring 6. The utility model combines a safety valve and a filter net as a whole and has the advantages of beautiful appearance, convenient cleaning, convenient installation, low cost, reliable operation, energy saving, etc.
Description
The utility model relates to a kind of valve, particularly relates to a kind of filtration safety valve that filters with the safety protection effect that plays that can be used on the liquid heating apparatus such as electric boiler and electrical shower.
On existing shower product, filter screen and safety valve are installed in respectively on the water inlet and water outlet of shower, and its defective is the manufacture cost height, and aesthetic property is poor, trouble is installed, and wastes energy.
The purpose of this utility model is to provide a kind of safety valve and filter screen is integrated, simple installation, and beautiful shape, it is convenient, with low cost to clean, reliable operation, but the filtration safety valve of energy saving.
For achieving the above object, the utility model provides a kind of filtration safety valve, this safety valve comprises valve body 1 and is contained in the interior spool 2 of valve body, it is characterized in that, described valve body 1 is an open column shape body, and its outer surface and endoporus are respectively equipped with outside thread 11 and internal thread 12, and its end end away from internal thread has an aperture 13, the eye bolt 4 that spool 2, spring 3 is housed in the valve body successively and is connected with internal thread 12, its other end is equipped with filter 5 and seal ring 6.
This valve is contained in the heater inleting pipe 7, and intake pipe is provided with the pipe joint 71,72 that links to each other with the intake pipe of water heater and heater respectively.
As seen from the above technical solution, the utility model links into an integrated entity safety valve and filter screen, not only have to filter and the safety protection dual functions, and this incorporate structure can effectively reduce production costs, and the simplification mounting process can also energy saving.Because the utility model is installed on the water inlet place of water heater, therefore can avoid reaching energy-conservation purpose because superpressure is discharged the water after shower heats.Again because the utility model is the internal and external threads linkage structure, therefore make product assembling and install and use more convenient.The utility model beautiful shape, it is convenient to clean, and cheap, reliable operation has very big practicability.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model parts sectional exploded views.
Fig. 2 is that the utility model is installed on the state of the installing and using outline drawing on the heater inleting pipe.
Consult Fig. 1, Fig. 2, filtration safety valve of the present utility model comprises valve body 1 and spool 2, its main points are, described valve body 1 is an open column shape body, its outer surface and endoporus are respectively equipped with outside thread 11 and internal thread 12, outside thread is used for being connected with water inlet tube of water heater, and internal thread then is used for being connected with eye bolt 4.Having a dozen away from an end end of internal thread on the valve body opens or closes and closes the aperture 13 that safety valve is used.The eye bolt 4 that spool 2, spring 3 is housed successively and is connected by perforate end to the other end in the valve body with internal thread 12, wherein spool 2 is a Cylindrical object, the one end has the less boss of a diameter, is used for socket spring 3, its other end by spring compression in described aperture 13 bottoms.Described eye bolt 4 one ends are provided with places the groove that spring is used, and the other end has the weep hole 41 that draining is used, and it is connected with internal thread 12 on the valve body inner bore.Being threaded is connected with a filter 5 by outer rim place, aperture 13 1 end end on the valve body, and this filter can be that cylinder is netted or dull and stereotyped netted, is the cylinder gauze filter in this example.This end outer rim also is equipped with seal ring 6.
Above-mentioned filtration safety valve is threadedly connected in the heater inleting pipe 7 by its outside thread 11, and intake pipe is provided with pipe joint 71,72, and wherein pipe joint 71 is connected with the heater inleting pipe, and pipe joint 72 is connected with the intake pipe of heater.
The utility model working principle as shown in Figure 1, when opening water valve, if water pressure in filtering the setting range of safety valve, then water safety valve elimination impurity wherein after filtration enters shower, again by discharging after the heater heats.When if water pressure exceeds the setting range that filters safety valve, the aperture 13 of water on valve body 1 washed spool 2 open, and 41 discharges of the weep hole on eye bolt 4, and the pressure of water can reduce rapidly, reaches effect of easing stress, thereby water heater is played a protective role.
