Abstract

The utility model relates to a valve for fluid delivery, in particular to an anti-freezing vacuation valve in an underneath type box of a solar water heater, comprising a valve body which is provided with a water inlet and a water outlet. A valve pipe perpendicular to the water inlet and the water outlet is arranged in the inner of the valve body. A through hole is arranged on the side wall of the valve pipe. A sliding piston is arranged in the valve pipe and is connected with a piston lever. A return spring is arranged between the piston lever and the valve pipe. A gap is left between the tail end of the valve pipe and the inner side wall of the valve body. A clapboard is arranged in the gap and a vacuation pipe runs through the clapboard is plug-in arranged on the clapboard. The vacuation pipe is covered on the water inlet and is extended to the outer of the water inlet. The utility model is with the function of the water in and out and vacuation and is of simple structure and easy realization.

Description

Antifreeze exhaust-valve in the solar water heater underneath type case

Technical field

The utility model relates to a kind of valve of carrying liquid, is antifreeze exhaust-valve in the solar water heater underneath type case specifically.

Background technique

Solar water heater all has one to be installed on outdoor water tank, and it is indoor to be connected to the user by water pipe, and in the winter of cold, outdoor water pipe is frozen in even bursting by freezing easily, causes and can't use.Prevent that one of effective ways that outdoor water pipe is frozen are exactly with the water emptying in the water pipe obsolete the time.

Summary of the invention

The purpose of this utility model provides antifreeze exhaust-valve in a kind of solar water heater underneath type case.

For achieving the above object, the utility model adopts following technological scheme:

Antifreeze exhaust-valve in the solar water heater underneath type case described in the utility model, comprise valve body, have water intake and water outlet on the valve body, it is characterized in that: the valve pipe perpendicular to water intake and water outlet is installed in the inside of valve body, have through hole on the sidewall of valve pipe, slidably piston is installed in the valve pipe, is connected with piston rod on the piston, between piston rod and the valve pipe return spring is installed; Leave the gap between the end of valve pipe and the madial wall of valve body, be provided with dividing plate in this gap, be fitted with the emptying pipe that runs through dividing plate on the dividing plate, emptying pipe is sleeved in the water intake, extends to the outside of water intake.

The mortor operated valve that promotes piston rod movement is installed in the outside of valve body.

The utility model collection water inlet and outlet and air emptying function are one, simple in structure, easy realization.

Description of drawings

Fig. 1 is an embodiment's of the utility model a structural representation;

Fig. 2 is a partial sectional view.

Embodiment

As shown in Figure 1 and Figure 2, antifreeze exhaust-valve in the solar water heater underneath type case described in the utility model comprises valve body 1, has water intake 2 and water outlet 3 on the valve body 1.Valve pipe 4 perpendicular to water intake 2 and water outlet 3 is installed in the inside of valve body 1, has through hole 8 on the sidewall of valve pipe 4, slidably piston 5 is installed in the valve pipe 4, be connected with piston rod 6 on the piston 5, between piston rod 6 and the valve pipe 4 return spring 7 is installed; Leave the gap between the madial wall of the end of valve pipe 4 and valve body 1, be provided with dividing plate 9 in this gap, be fitted with the emptying pipe 10 that runs through dividing plate 9 on the dividing plate 9, emptying pipe 10 is sleeved in the water intake 2, extends to the outside of water intake 2.The mortor operated valve that promotes piston rod 6 motions is installed in the outside of valve body 1.The structure and the principle of concrete mortor operated valve are known technology, are not described in detail in this.

During use, this exhaust-valve is installed in the lowest part of solar water heater water tank, water intake 2 is installed in water tank inside, and water outlet 3 is positioned at the water tank outside, is connected with upper and lower conduit.Usual this exhaust-valve is in emptying state, is arranged in the air importing valve body 1 of the emptying pipe 10 of solar water heater water tank inside with the water tank top, enters upper and lower conduit.And this moment, piston 5 is valve pipe 4 sealing, the water in the water tank can not be by valve pipe 4, at this time as long as the valve of user side be in open mode just can be with the water emptying in the upper and lower conduit.

When needs up and down water the time, as long as handle mortor operated valve, promote piston rod 6, piston 5 move inwards, opens valve pipe 4, makes intake pipe 2 form the passage of an opening by through hole 8, valve pipe 4, valve body 1 and water outlet 3, thus water about realizing.
