Description

Technical Field

[0001] This utility model relates to the field of gauge valve technology, and in particular to a gauge valve. Background Technology

[0002] Currently, in the air conditioning and refrigeration industry, the commonly used refrigerant dual valve generally includes a valve body, on which a low-pressure gauge and a high-pressure gauge are installed respectively. The low-pressure gauge controls the low-pressure valve core to open and close the low-pressure connecting pipe through the low-pressure handle, and the high-pressure gauge controls the high-pressure valve core to open and close the high-pressure connecting pipe through the high-pressure handle. The low-pressure connecting pipe is connected to the air conditioning three-way valve refrigerant charging port, and the high-pressure pressure pipe is connected to the air conditioning two-way valve refrigerant charging port. The middle pipe of the dual valve is connected to a vacuum pump or a gas cylinder nozzle. Chinese patent CN118167833A discloses a new type of dual valve structure.

[0003] The valve's intermediate pipeline is first connected to a vacuum pump for evacuation, then the vacuum pump is disconnected and switched to a refrigerant cylinder for refrigerant charging. However, this type of valve has the following disadvantages and deficiencies:

[0004] The intermediate management process involves time-consuming and labor-intensive switching between vacuum pumps and refrigerant bottles, significantly increasing manual labor costs and resulting in low switching efficiency, thereby reducing production efficiency. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing an integrated dual-interface valve that enables rapid switching between vacuum pumps and refrigerant bottles, reducing labor intensity and improving work efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a gauge valve, comprising a valve body and a gauge disposed on both sides of the valve body;

[0007] The valve body is symmetrically provided with a first interface connected to the vacuum pump and a second interface connected to the gas cylinder.

[0008] The first and second interfaces are opened and closed by the first and second knobs, respectively, to switch between the gauge valve, vacuum pump and gas cylinder.

[0009] In the above scheme, preferably, both the first knob and the second knob are provided with positioning elements, and the valve body is slidably provided with locking elements that cooperate with the positioning elements.

[0010] In the above scheme, preferably, the locking member is provided with a locking groove that engages with the locking member, and the locking member is slidably connected to the valve body via a lifting rod.

[0011] In the above-mentioned scheme, preferably, the locking component is provided with a handle.

[0012] In the above scheme, preferably, the locking component includes a lifting plate and a guide plate, the lifting rod is disposed on the lifting plate, and the locking groove is disposed on the guide plate;

[0013] The guide plate end face is fitted to the valve body surface.

[0014] In the above scheme, preferably, the valve body is slidably provided with a locking rod that locks the other locking member after the locking member on one side moves;

[0015] The locking component is provided with drive grooves for accommodating both ends of the locking rod.

[0016] In the above scheme, preferably, the valve body is provided with a mounting seat that cooperates with the locking rod, and springs that cooperate with the mounting seat are symmetrically provided on both sides of the locking rod.

[0017] In the above scheme, preferably, the locking rod includes a sliding part, the sliding part is slidably connected to the mounting base, and the diameter of the sliding part is smaller than the diameter of both ends of the locking rod;

[0018] The spring is sleeved on the sliding part.

[0019] In the above scheme, preferably, the handle includes an extension rod and a lifting block, wherein the outer edge of the lifting block is larger than the outer edge of the extension rod.

[0020] In the above scheme, preferably, the lifting plate and the guide plate are integrally formed from sheet metal, with an included angle of 90° between them, and the lifting rod is vertically arranged on the upper surface of the valve body.

[0021] The beneficial effects of this utility model are: through the dual-interface independent control design, this utility model eliminates the need for the traditional valve to repeatedly disassemble and reconnect pipelines between the vacuum pump and the refrigerant bottle, thus greatly shortening the switching time and significantly improving work efficiency.

[0022] Meanwhile, a dual protection mechanism of knob locking and linkage locking device is adopted. Through the snap-fit ​​cooperation between the positioning part and the locking groove, and the mechanical interlock between the locking rod and the drive groove, it is ensured that the knob on the other side is automatically locked when one side channel is opened, thus fundamentally avoiding the risk of refrigerant leakage caused by accidental opening of both channels.

[0023] In addition, the optimized ergonomic design includes a damped lifting structure with a handle and a guide plate that fits the valve body surface, enabling convenient one-handed operation and enhancing structural stability; modular components combined with a spring reset mechanism reduce maintenance difficulty and improve equipment reliability.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-4 .

[0029] A gauge valve includes a valve body 1 and gauge valves 2 symmetrically disposed on both sides of the valve body 1.

[0030] Valve body 1 is provided with:

[0031] First interface 101: Connects to a vacuum pump, and its opening and closing are controlled by the first knob 103. It is set... Figure 1 The left side of valve body 1 shown;

[0032] Second interface 102: Connects to a refrigerant cylinder, and its opening and closing are controlled by a second knob 104. It is set at... Figure 1 The right side of valve body 1 is shown.

[0033] The first knob 103 and the second knob 104 are as follows Figure 1 The valve body 1 is shown to be set on the left and right sides of the front of the valve body 1 and rotates with the valve body 1. By independently operating the first knob 103 and the second knob 104, the vacuum pump and the gas cylinder can be switched without disassembly.

[0034] Both the first knob 103 and the second knob 104 are provided with positioning elements 105. The positioning element 105 is pin-shaped and is disposed on the circumference of the knob. Initially, both the first knob 103 and the second knob 104 are in the closed state, at which time the positioning element 105 is vertically upward. Figure 1 and Figure 2 As shown;

[0035] A locking element 106 is vertically slidably connected to the valve body 1. The locking element 106 is composed of a lifting plate 11 and a guide plate 12 integrally formed from sheet metal, with an included angle of 90° between them. The lifting plate 11 is parallel to the upper surface of the valve body 1, and the guide plate 12 is parallel to the front surface of the valve body 1. A locking groove 107 that cooperates with the positioning element 105 is opened at the lower end face of the guide plate 12. A lifting rod 108 that is damped and slidably connected to the valve body 1 is provided on the guide plate 12. The lifting rod 108 is vertically arranged on the lifting plate 11, and the end face of the guide plate 12 is in contact with the surface of the valve body 1. The outer surface of the lifting rod 108 is a damping surface, which has a certain damping when it cooperates with the sliding hole on the valve body 1, and can only be moved by manual lifting.

[0036] A handle 109 is provided at the top of the end face of the guide plate 12 of the locking member 106 on the side away from the valve body 1; the handle 109 includes an extension rod 21 and a lifting block 22 with an outer edge larger than the extension rod 21; such as Figure 3 As shown, the handle 109 drives the locking member 106 to perform vertical lifting and lowering operations relative to the valve body 1.

[0037] A locking rod 3 that slides laterally is provided at the middle of the outer end face of the valve body 1. A drive groove 301 is provided on the end face of the locking member 106 near the locking rod 3. The two ends of the locking rod 3 can be moved and inserted into the drive groove 301, so that the other side is automatically locked when the locking member 106 on one side moves. The locking rod 3 includes a sliding part 304 provided in the middle. The diameter of the sliding part 304 is smaller than the diameter of the two ends of the locking rod 3. The sliding part 304 and the locking rod 3 at both ends can be fixed together by threaded connection. The valve body 1 is provided with a mounting seat 302. The locking rod 3 is slidably connected to the mounting seat 302 through the sliding part 304. Springs 303 are sleeved on both sides of the sliding part 304 and elastically abut against the end faces on both sides of the mounting seat 302.

[0038] Initially, both ends of the locking rod 3 are positioned at the openings of the drive grooves 301 of the two locking members 106, with part of it entering the openings. The drive grooves 301 have rounded transitions on both sides. When one locking member 106 is pulled upward, the drive groove 301 on that side slides upward and presses the end of the locking rod 3 placed in the groove, causing it to slide to the other side. At the same time, the spring 303 on that side is compressed. After the locking rod 3 is compressed, the other end inserts into the drive groove 301 of the locking member 106 on the other side, thereby fixing the locking member 106 on the other side and making it difficult to pull it up. This achieves the function of automatically locking the other side when one locking member 106 is active.

[0039] Using a valve as described above:

[0040] 1. Vacuuming stage:

[0041] In such Figure 1 In the direction shown, lift the left handle 109 to disengage the locking member 106 from the positioning member 105 of the first knob 103;

[0042] Turn the first knob 103 to open the first interface 101 and connect it to the vacuum pump;

[0043] The linkage locking lever 3 is inserted into the right drive slot 301 under the action of the spring 303, locking the second knob 104.

[0044] 2. Refrigerant charging stage:

[0045] Close the first knob 103 and drive the left handle 109 downward so that the locking groove 107 of the left locking member 106 engages with the positioning member 105 on the first knob 103 to lock the first knob 103. At the same time, the right end of the locking rod 3 slides away from the inner cavity of the drive groove 301 of the right locking member 106 under the action of the spring 303.

[0046] Lifting the right handle 109 causes the linkage locking lever 3 to slide to the left and insert into the drive groove 301 of the left locking component 106;

[0047] Turn on the second knob 104 to connect the refrigerant cylinder for seamless switching.
