Description

Technical Field

[0001] This invention relates to the field of pressure relief valve technology, specifically a waterproof pressure relief valve. Background Technology

[0002] Traditional pressure relief valves are all IP55 waterproof. In cities with abundant rainfall, the signal switch of the pressure valve is prone to short circuit and malfunction due to long-term exposure to rain and high humidity. Summary of the Invention

[0003] The purpose of this invention is to provide a waterproof pressure relief valve to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a waterproof pressure relief valve, comprising a valve seat, a bolt hole being formed on the outer wall of the top end of the valve seat, a pressure adjusting bolt being threaded into the inner cavity of the bolt hole, a spring plate being fixedly connected to the outer wall of the pressure adjusting bolt, a reed being fixedly connected to the top end of the spring plate, a valve cover being fixedly connected to the top end of the spring plate, a marker rod being fixedly connected to the top end of the valve seat, a magnetic ring being embedded in the inner cavity of the marker rod, and a connecting cable being bolted to the outer wall of the valve cover.

[0005] Preferably, the top of the outer wall of the valve cover is bolted with a locking clip.

[0006] Preferably, the locking clip is a "C" shaped clip.

[0007] Preferably, the valve cover and the locking clip are fixedly connected to the top of the marker rod by screws.

[0008] Preferably, the connecting cable adopts an aviation plug cable connection method.

[0009] Preferably, the outer wall of the reed switch is fitted with a process groove, and the process groove is fixedly connected to the compression spring plate.

[0010] Preferably, the pressure adjusting bolt is a half-thread bolt.

[0011] Preferably, the number of pressure adjusting bolts is four, and they are evenly spaced around the top of the valve seat.

[0012] Preferably, the valve seat has mounting holes at its four corners.

[0013] Preferably, the outer wall of the compression spring plate has through holes around its perimeter.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Unlike previous pressure relief valves that used microswitches as signal generators, this waterproof pressure relief valve uses a reed switch as the signal generator.

[0015] 2. For this waterproof pressure relief valve, the bottom of the reed switch also needs to be welded with wire ends to seal the welding contact points and the entire reed switch to protect the reed switch from damage and also to waterproof the welding contact points.

[0016] 3. This waterproof pressure relief valve uses an aviation plug for wiring, which solves the problem of traditional terminals not being waterproof.

[0017] 4. This waterproof pressure relief valve has a magnetic marker rod with a magnetic ring embedded in it. When the pressure valve is activated, the magnetic ring contacts the reed switch, and the reed switch is attracted and sends a signal under the action of the magnetic field.

[0018] 5. This waterproof pressure relief valve features an integrally cold-forged stretched valve seat. Traditional valve seats are made using a casting process, which results in internal pores that affect sealing and quality. The current process uses a stretching process to extrude aluminum plates into the shape of the valve seat.

[0019] 6. This waterproof pressure relief valve is a type with a standard half-thread bolt for adjusting spring pressure.

[0020] 7. This waterproof pressure relief valve allows for quick disassembly of the C-type hook lock anti-action locking clip, solving the problem that traditional single-line locking devices are not easy to disassemble. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 This invention provides a technical solution: a waterproof pressure relief valve, including a valve seat 1, which is an integrally cold-forged stretched valve seat. Traditional valve seats 1 are made using a casting process, resulting in internal pores that affect sealing and quality. This invention uses a stretching process to extrude an aluminum plate into the shape of the valve seat 1. Bolt holes are provided on the outer wall of the top of the valve seat 1, and pressure adjusting bolts 2 are threaded into the inner cavity of these bolt holes. The pressure adjusting bolts 2 are half-threaded bolts. Traditional pressure relief valves are inconvenient for adjusting the operating pressure (relief pressure value). Using standard parts not only saves costs but also allows for adjustment of the operating pressure through the threads of the half-threaded bolts 2 and the depth of the bolt holes in the valve seat 1. Four pressure adjusting bolts 2 are evenly spaced around the top of the valve seat 1. A spring plate 3 is fixedly connected to the outer wall of the plug 2. Through holes are provided around the outer wall of the spring plate 3. A reed switch 4 is fixedly connected to the top of the spring plate 3. The reed switch 4 is protected by a protective casting process. Because the reed switch 4 is made of sintered glass, the surface glass is very fragile. The reed switch 4 is installed and limited in the process groove 9, which is fixedly connected to the spring plate 3 of the pressure valve. After installation, silicone and epoxy resin are poured into the process groove 9. The bottom of the reed switch 4 also needs to be soldered to the female connector of the aviation plug cable 8. Sealing the soldering contact points and the entire reed switch 4 with adhesive protects the reed switch 4 from damage and also makes the soldering contact points waterproof. This process is applicable to all models of pressure valves. The wiring mode uses an aviation plug, solving the problem of traditional terminals not being waterproof. Traditional pressure relief valves use conventional terminals, which are not waterproof. In humid weather or when the external switch box is poorly sealed, water or condensation can accumulate inside the junction box, causing short circuits between terminals and malfunctions. Replacing them with aviation connectors can achieve an IP68 protection rating, perfectly avoiding and solving the problem of non-waterproof terminals. The outer wall of the reed switch 4 is fitted with a process groove 9, which is fixedly connected to the spring plate 3. The top of the spring plate 3 is fixedly connected to the valve cover 5, and the top of the valve seat 1 is fixedly connected to the indicator rod 6. A magnetic ring is embedded in the inner cavity of the indicator rod 6. When the pressure valve is activated, the magnetic ring contacts the reed switch 4, and the reed switch 4 is attracted and sends a signal under the action of the magnetic field. The outer wall of the valve cover 5 is bolted with a connecting cable 8, which uses an aviation connector for cable connection.

[0025] As a preferred option, the top of the outer wall of the valve cover 5 is bolted with a locking clip 7, which is a "C"-shaped clip. The valve cover 5 and the locking clip 7 are fixedly connected to the top of the marker rod 6 by screws. The locking clip 7 is a quick-release "C"-shaped hook lock anti-action locking clip, which solves the problem that the traditional single-bar locking device is not easy to disassemble. The traditional locking device uses two bolts for clamping and disassembly, which is troublesome and also detrimental to product quality. The "C"-shaped hook lock anti-action locking clip can be disassembled in one go by the screw in the center.

[0026] As a preferred option, the valve seat 1 is further provided with mounting holes at the four corners of its top end, which facilitates the installation of the valve seat with the outside.
