However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0014] The present utility model will be further described below in conjunction with the drawings and preferred embodiments.
[0015] Embodiment 1
[0016] Refer to Figure 1 As shown, an airtightness testing device for a heater water valve involved in this embodiment includes a test base 1. An installation groove 2 for clamping the heater water valve is provided on the test base 1, and a rotary clamping cylinder 3 for pressing the heater water valve from top to bottom. A first plug 4 is provided on one side of the installation groove 2, and a second plug 5 is provided on the other side. Linear reciprocating motion mechanisms (not shown) for controlling the movement in the direction of approaching or departing from the installation groove are provided on both the first plug 4 and the second plug 5. The linear reciprocating motion mechanism is a push rod cylinder. A test pool 6 filled with water is opened on the test base 1;
[0017] An air inlet channel (not shown) is opened on the first plug 4. One end of the air inlet channel is connected to an air supply source (not shown), and the other end is opened on the end face of the first plug 4 facing the installation groove 2. An air outlet channel (not shown) is opened on the second plug 5. One end of the air outlet channel is connected to the test pool 6 through a pipe, and the other end is opened on the end face of the second plug 5 facing the installation groove 2. The connection part of the air outlet channel and the test pool through the pipe is immersed in the liquid.
[0018] Furthermore, a transparent cover plate 7 is provided on the test pool 6, and the cover plate 7 is made of acrylic material.
[0019] Furthermore, a positioning pin 8 is provided on the test base 1.
[0020] In this embodiment, first, a warm air valve in a closed state is clamped in the installation groove 2, and the rotating clamping arm on the rotating clamping cylinder 3 is used to press the warm air valve. Then, the linear reciprocating motion mechanism controls the first plug 4 and the second plug 5 to move horizontally until the first plug 4 is inserted into one end valve port of the warm air valve and the second plug 5 is inserted into the other end valve port of the warm air valve. Finally, air is supplied to the air inlet passage. If there is internal leakage in the warm air valve, gas will escape from the air outlet passage, flow along the pipeline into the test pool 6, and generate bubbles, so as to judge whether the warm air valve leaks.
[0021] Among them, through the setting of the transparent cover plate 7, while covering the test pool 6, the situation inside the pool can still be visually judged.
[0022] Among them, through the setting of the positioning pin 8, it is used for precise positioning when the warm air valve is clamped.
[0023] The airtightness test device for the warm air valve involved in the present utility model clamps the warm air valve in a closed state, supplies air to one end of it, and detects whether there is air leakage at the other end. If leaked gas is generated, it will flow into the test pool along the pipeline and generate bubbles, with intuitive judgment. Moreover, the overall structure is simple, the failure rate is low, the functions are perfect, and the practicability is strong.
