Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.
Referring to the accompanying drawings 1 and 2 of the specification, a two-way valve device is vertically installed when in use, and comprises a valve body 1, an inner body 2 and a sealing ball 3, wherein the valve body 1 is provided with an inlet 11 and an outlet 12, the inlet 11 is communicated with a heat storage tank, the inner body 2 is arranged in the valve body 1, an accommodating space 21 is a hollow structure which is opened up and down, and the sealing ball 3 is arranged in the accommodating space 21 of the inner body; in addition, an upper sealing ring 41 is placed on the upper end of the outer periphery of the inner body 2, a lower support 42 is placed on the lower end, when the sealing ball 3 is positioned at the lower end of the inner body 1 under the action of self gravity, a gap a is formed between the sealing ball 3 and the lower end of the inner body 1, and gas can be discharged into the accommodating space 21 of the inner body from the gap a and finally discharged from the outlet 12 of the valve body. Of course, the two-way valve device may not include the inner body 2, the accommodating space 21 may be directly formed in the valve body 1, and the upper seal ring 41 and the lower support 42 may be disposed at the upper and lower ends of the accommodating space 21, so that when the ball seal is located at the lower end portion of the accommodating space 21, the gap a through which the gas can be discharged is also formed between the ball seal 3 and the valve body 1, and the function of discharging the gas from the gap can also be achieved.
In another preferred embodiment, referring to fig. 1 and 2, a two-way valve device is installed in a vertical manner when in use, and comprises a valve body 1, an inner body 2 and a sealing ball 3, wherein the valve body 1 is provided with an inlet 11 and an outlet 12, the inner body 2 is arranged in the valve body 1, the accommodating space 21 is a hollow structure which is opened up and down, and the sealing ball 3 is arranged in the accommodating space 21 of the inner body; in addition, an upper seal ring 41 is placed on the upper end of the outer periphery of the inner body 2, and a lower seal ring 42' is placed on the lower end, so that when the sealing ball 3 is positioned at the lower end 11 of the inner body 1 under the action of self gravity, a gap a is formed between the sealing ball 3 and the lower end 11 of the inner body 1, and gas can be discharged into the inner body 2 from the gap a and finally discharged from the outlet 12 of the valve body.
