Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of filling valve, especially to a filling valve of active control. BACKGROUND

[0002] The air conditioner filling valve is an important component of adding refrigerant, and its main function is to inject refrigerant into the refrigeration system to ensure the refrigeration effect of the equipment during operation. With the passage of time, the air conditioning system may be caused by pipeline leakage and other reasons to cause insufficient refrigerant, and then affect the overall performance of the equipment. The filling valve is usually made of metal material, and its structure is simple and firm. Its design allows professionals to conveniently connect the filling device and quickly complete the refrigerant filling. The operation of the filling valve is relatively simple, and usually only needs to be connected with the filling pipeline to perform the filling operation.

[0003] When the filling valve is used, it needs to be connected with the filling port on one side of the air conditioner first. The existing air conditioner filling port is internally provided with a sealing plug. When the filling valve is connected with the filling port, the sealing plug is pushed open by the filling valve to enable the cooling liquid to be normally filled. However, the sealing plug is opened at the same time, and the filling valve and the filling port are still in the state of continuous connection, which causes the sprayed refrigerant to easily cause frostbite to the worker. Therefore, the problem needs to be solved. UTILITY MODEL CONTENTS

[0007] As a further embodiment of this utility model, the limiting mechanism includes a limiting rod, which is slidably connected to one side of the mounting groove. A pull plate is fixedly connected to the end of the limiting rod away from the top rod. A tension spring is sleeved on the surface of the limiting rod near the mounting groove. The bottom end of the tension spring is fixedly connected to the top of the pull plate, and the top end of the tension spring is fixedly connected to one side of the mounting groove. A limiting groove is formed on the surface of the main body near the limiting rod. The limiting rod and the limiting groove are configured to cooperate with each other. By setting the limiting rod, the adjusting plate can be limited.

[0008] As a further embodiment of this utility model, the expansion mechanism includes a T-shaped groove, which is formed on the top of the adjusting plate. A turntable is rotatably connected inside the T-shaped groove. A connecting rod is fixedly connected to the top of the turntable. A piston cylinder is fixedly connected to the top of the connecting rod. The piston cylinder is slidably connected to the piston chamber. The piston cylinder, piston chamber, and airbag are arranged in cooperation with each other. A first connecting pipe is fixedly connected to one side of the main body. A fixing ring is installed on the surface of the second connecting pipe near the airbag. The airbag can be inflated by the piston cylinder.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by employing a technique of moving the sealing plug via a push rod, avoids frostbite on workers. It effectively solves the problem of refrigerant spraying out and causing frostbite to workers while the charging valve and charging port remain connected, even when the sealing plug is open. A push rod is installed on one side of the adjusting plate, and this push rod cooperates with the main body at the bottom of the second connecting pipe. When the adjusting plate is rotated, the push rod moves upward, thus opening the sealing plug in the air conditioner charging port. Since the second connecting pipe is already connected to the charging port, opening the sealing plug prevents frostbite on workers. When the piston cylinder moves inside the piston chamber, it fills the gas bladder with gas, causing the bladder to expand. The expanded bladder seals the gap between the second connecting pipe and the charging port, preventing leakage during the charging process. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Reference Figure 1 - Figure 4 An actively controllable filling valve includes a main body 1. A push rod 201 is rotatably connected to one side of the main body 1. The push rod 201 and the main body 1 are configured to cooperate with each other. An adjusting plate 2 is fixedly connected to one end of the push rod 201. Two mounting grooves 203 are opened on the surface of the adjusting plate 2 away from the push rod 201. Each of the two mounting grooves 203 is equipped with a limiting mechanism for limiting the adjusting plate 2. The push rod 201 can be controlled by the adjusting plate 2. A second connecting pipe 102 is fixedly connected to the end of the main body 1 away from the adjusting plate 2. A storage chamber 105 is opened on the end of the second connecting pipe 102 away from the adjusting plate 2. An air bladder 106 is installed inside the storage chamber 105. Three piston chambers 104 are opened on the inner surface of the storage chamber 105. The three piston chambers 104 are evenly arranged in a ring. Each of the three piston chambers 104 is equipped with an expansion mechanism for expanding the air bladder 106. The push rod 201 can prevent workers from suffering frostbite.

[0019] Preferably, the limiting mechanism includes a limiting rod 401, which is slidably connected to one side of the mounting groove 203. A pull plate 4 is fixedly connected to the end of the limiting rod 401 away from the top rod 201. A tension spring 402 is sleeved on the surface of the limiting rod 401 near the mounting groove 203. The bottom end of the tension spring 402 is fixedly connected to the top of the pull plate 4, and the top end of the tension spring 402 is fixedly connected to one side of the mounting groove 203. The tension spring 402 can be used to reset the limiting rod 401. A limiting groove 107 is opened on the surface of the main body 1 near the limiting rod 401. The limiting rod 401 and the limiting groove 107 are configured to cooperate with each other. The limiting rod 401 can limit the adjustment plate 2.

[0020] Furthermore, the expansion mechanism includes a T-shaped groove 202, which is located on the top of the adjusting plate 2. A turntable 3 is rotatably connected inside the T-shaped groove 202, and a connecting rod 301 is fixedly connected to the top of the turntable 3. The turntable 3 allows the connecting rod 301 to move upward stably. A piston cylinder 302 is fixedly connected to the top of the connecting rod 301, and the piston cylinder 302 is slidably connected to the piston chamber 104. The piston cylinder 302, the piston chamber 104, and the airbag 106 are arranged in cooperation with each other. A first connecting pipe 101 is fixedly connected to one side of the main body 1, and a fixing ring 103 is installed on the surface of the second connecting pipe 102 near the airbag 106. The piston cylinder 302 allows the airbag 106 to expand.

[0021] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, the second connecting pipe 102 is first connected to the air conditioner charging port through the fixing ring 103. After the connection is completed, the adjusting plate 2 can be rotated. A push rod 201 is installed on one side of the adjusting plate 2, and the push rod 201 cooperates with the main body 1 at the bottom of the second connecting pipe 102. Thus, when the adjusting plate 2 is rotated, the push rod 201 can be moved upward, thereby enabling it to push open the sealing plug in the air conditioner charging port. Since the second connecting pipe 102 has been connected to the charging port, when the sealing plug is pushed open, the phenomenon of frostbite on workers can be avoided. A piston cylinder 302 is also installed on one side of the adjusting plate 2. The piston cylinder 302 is connected to the adjusting plate 2 via the turntable 3. Therefore, when the adjusting plate 2 rotates upward, the piston cylinder 302 can move upward normally. A piston chamber 104 is provided inside the main body 1, and the piston cylinder 302 slides inside the piston chamber 104. An air bladder 106 is installed on the top of the piston chamber 104, and the air bladder 106 is configured to communicate with the piston chamber 104. Thus, when the piston cylinder 302 moves inside the piston chamber 104, the gas inside the piston chamber 104 can be filled into the air bladder 106, thereby allowing the air bladder 106 to expand. The expanded air bladder 106 can seal the gap between the second connecting pipe 102 and the filling port to prevent leakage during the filling process.
