Abstract

The utility model discloses a water inlet valve, and comprises a valve body, and a water inlet and a water outlet which are arranged on two ends of the valve body, wherein, the top of the valve body is provided with a pressure-releasing valve, a cylindrical valve body is arranged inside the inner cavity of the valve body, a ring-shaped groove is arranged at the outer side of the circumference of the valve core, and the outer side of the circumference of the valve core is provided with a run-through water hole on the radial direction. Since a pressure-releasing valve is arranged on the surface of the valve body, the utility model has the functions of a water inlet valve and a safety pressure-releasing valve, thereby saving the mounting cost and realizing the simple operation and the convenient utilization; moreover, since a valve core with a ring-shaped groove is arranged inside the inner cavity of the valve body, the utility model can prevent the damage of the electric water heater due to the water shortage caused by the closing of the water inlet valve because of the artificial mistake.

Description

A kind of inlet valve

Technical field

The utility model relates to a kind of inlet valve that is used for electric water heater, particularly a kind of inlet valve that has the pressure release function.

Background technique

Storage-type electric water heater is developed rapidly with its easy to use, comfortable characteristics, but accessory does not also obtain due attention so far.Particularly inlet valve function dullness must be installed with other parts, makes the superior function of storage-type electric water heater can not get fully playing.At present, generally the water intake at electric water heater is installed into water valve, at another place safety relief valve is installed, and can cause operation inconvenience like this, and installation cost is higher relatively.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of inlet valve that has the pressure release function, and is simple to operate, easy to use.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of inlet valve comprises valve body, is positioned at the water intake and the water outlet at valve body two ends, and the end face of described valve body is equipped with Decompression valves, and the inner chamber of valve body is equipped with the cylindrical body spool, and the periphery of spool is provided with the groove of annular, radially is provided with the water port of perforation.

As further preferred implementation of the present utility model, described Decompression valves is arranged between spool and the water outlet with the screw that is connected of valve body, and the end of described spool is connected with handwheel by the handwheel rotating shaft.

The beneficial effects of the utility model are: because the mounted on surface of valve body has Decompression valves, make the utility model possess the function of inlet valve and safety relief valve, saved installation cost, and simple to operate, easy to use; And be provided with the spool of band connected in star at body cavity, can prevent because human error is closed inlet valve and caused lack of water and damage electric water heater.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of inlet valve of the present utility model, a kind of inlet valve, comprise valve body 1, be positioned at the water intake 11 and the water outlet 12 at valve body 1 two ends, it is characterized in that the end face of described valve body 1 is equipped with Decompression valves 3, the inner chamber 13 of valve body 1 is equipped with cylindrical body spool 2, the arranged outside of spool 2 has the groove 21 of annular, radially is provided with the water port 22 of perforation.

With reference to Fig. 3 to Fig. 5, in the present embodiment, the outer side surface of water intake 11 is provided with screw thread, can connect the nut connector of water supply line, and the inboard of water outlet 12 is provided with screw thread equally to connect the water pipe of electric water heater.When inlet valve was opened, cold water was from the inner chamber 13 of water intake 11 inflow valve bodies 1, and by the water port 22 and the water outlet 12 of spool 2, the heating water chamber that enters electric water heater heats.The end of spool 2 is connected with handwheel 4 by the handwheel rotating shaft 41 of passing valve body 1 side through hole 15, can control the closure of inlet valve by rotating handwheel 4 when people use, thereby adjust the size that enters the electric water heater current.

Decompression valves 3 is arranged between spool 2 and the water outlet 12 with the screw 14 that is connected of valve body 1, and there is threaded connecting end 35 described pressure release valve housing 31 bottoms and is connected screw 14 and links to each other.Cap 32 is regulated to be threaded in described housing 31 tops, and the housing inner chamber is provided with T-valve bar 33, and described T-valve bar 33 peripheries are with spring 34.T-valve bar 33 compresses through hole 36 under the effect of spring 34 makes Decompression valves 3 keep normally closed, and people can be by adjusting the cracking pressure that the height of regulating cap 32 is regulated Decompression valves 3.When inlet valve is turned down or is closed, coolant-temperature gage in the heating water chamber of electric water heater raises, when its pressure surpasses Decompression valves 3 predefined pressure, aqueous vapor can boost T-valve bar 33, discharge from the space between T-valve bar 33 and the adjusting cap 32, pressure in the heating water chamber is reduced, avoid pressure in the heating water chamber excessive and explosion causes contingency.

In addition, the periphery of spool 2 is provided with the groove 21 of annular, makes water intake 11 and water outlet 12 keep normal open, even if inlet valve is when human error is closed, still there are a spot of current can enter electric water heater, avoid electric water heater lack of water operation and be damaged.

A kind of inlet valve of the present utility model has possessed the function of inlet valve and safety relief valve, can save installation cost, and is simple to operate, easy to use.
