Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a solenoid valve with a pressure reducing function. Background Art

[0002] As a modern commonly used conveying control device, the solenoid valve has the main function of connecting to an external conveying pipeline. When electrical energy is conveyed to the interior of the solenoid valve through an external control component, the solenoid valve drives the transmission plug to block the interior of the solenoid valve, thereby completing the conveying control inside the conveying pipeline. However, the existing solenoid valve lacks a pressure reducing auxiliary component. When the pressure inside the solenoid valve is too high, the pressure inside the solenoid valve cannot be relieved, thereby affecting the safety of the solenoid valve.

[0003] Compared with the existing solenoid valve, the utility model adds a pressure reducing auxiliary component. When the pressure in the solenoid valve is too high, the pressure inside the solenoid valve can be relieved, thereby preventing the solenoid valve from rupture due to excessive pressure, thereby improving the safety of the solenoid valve. Utility Model Content

[0004] The purpose of the utility model is to provide a solenoid valve with a pressure reducing function to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: comprising a valve body and a fixing ring, wherein two sets of fixing rings are installed on the outer surface of the valve body, and eight sets of threaded fixing holes are opened through the outer surface of the fixing ring;

[0006] A pressure sensor is installed on the front of the valve body, and two groups of buzzers are installed on the front of the valve body, and the buzzers are located outside the pressure sensor.

[0007] Preferably, an electromagnetic relay is installed on the back side of the valve body.

[0008] Preferably, a pressure relief pipe is installed through the bottom of the valve body, and an electric telescopic rod is installed through the front of the pressure relief pipe.

[0009] Preferably, a fixing plate is installed inside the pressure relief pipe.

[0010] Preferably, a shielding block is embedded and connected inside the fixing plate, and the shielding block is connected to the electric telescopic rod.

[0011] Preferably, a connecting bolt is installed on the top of the valve body, and a shielding cover is installed on the top of the connecting bolt through bolts.

[0012] Preferably, an electromagnetic controller is installed through the top of the shielding cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is equipped with a pressure sensor, a buzzer, an electromagnetic relay, a pressure relief pipe, an electric telescopic rod and a blocking block. The pressure sensor detects the pressure inside the valve body. When the pressure inside the valve body is too high, the pressure sensor transmits an electrical signal to the inside of the electromagnetic relay. The electromagnetic relay drives the switch inside it to connect, and transmits electrical energy to the inside of the buzzer and the electric telescopic rod respectively. At the same time, the small pick inside the buzzer vibrates at a high frequency and makes a sharp sound, thereby reminding the surrounding staff that the internal pressure of the solenoid valve is too high. When the electrical energy is transmitted to the inside of the electric telescopic rod via the electromagnetic relay, the electric telescopic rod contracts, driving the blocking block to contract to the inside of the fixed plate, and driving the inside of the pressure relief pipe to connect.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] like Figure 1 , Figure 2 and Figure 3As shown, a solenoid valve with a pressure reducing function proposed by the utility model comprises a valve body 1 and a fixing ring 2. Two groups of fixing rings 2 are installed on the outer surface of the valve body 1. The valve body 1 provides fixing points for the fixing rings 2, pressure sensors 4, buzzers 5, electromagnetic relays 6, pressure relief pipes 7 and connecting bolts 11 installed on its outer surface. At the same time, when water is transported to the inside of the valve body 1, the valve body 1 transports the water to the inside of an external delivery pipeline to complete the transportation of the water. The fixing ring 2 is installed on the outer surface of the valve body 1 to provide fixing points for threaded fixing holes 3 penetrated through the outer surface of the valve body. Eight groups of threaded fixing holes 3 are penetrated through the outer surface of the fixing ring 2. Before using the device, insert the external bolts into the inside of the threaded fixing holes 3, and insert the external bolts into the inside of the external delivery pipeline. The solenoid valve is fixed; a connecting bolt 11 is installed on the top of the valve body 1, and the connecting bolt 11 is installed to the top of the valve body 1 to provide a fixing point for a shielding cover 12 connected to the top by bolts. A shielding cover 12 is installed on the top of the connecting bolt 11 by bolts, and the shielding cover 12 is installed to the top of the shielding cover 12 by bolts to ensure the sealing of the valve body 1 and provide a fixing point for the electromagnetic controller 13 installed on the top. The electromagnetic controller 13 is installed through the top of the shielding cover 12. When it is necessary to block the inside of the valve body 1, electric energy can be transmitted to the inside of the electromagnetic controller 13 via an external control component. At this time, the electromagnetic coil inside the electromagnetic controller 13 drives the transmission plug to move downward to block the inside of the valve body 1 through the electromagnetic effect.

[0022] The working principle of a solenoid valve with a pressure reducing function based on the first embodiment is: first, an external bolt is inserted into the interior of the threaded fixing hole 3, and the external bolt is inserted into the interior of the external delivery pipe to complete the fixation of the solenoid valve; when water is delivered to the interior of the valve body 1, the valve body 1 delivers the water to the interior of the external delivery pipe to complete the delivery of the water; when the interior of the valve body 1 needs to be blocked, electric energy can be delivered to the interior of the electromagnetic controller 13 via an external control component; at this time, the electromagnetic coil inside the electromagnetic controller 13 drives the transmission plug to move downward via the electromagnetic effect to block the interior of the valve body 1, thereby controlling the delivery pipe.

When the interior of the pressure relief pipe 7 is connected, the pressure relief pipe 7 transports the water to the interior of the external receiving component, reduces the pressure inside the valve body 1, and thus improves the safety inside the valve body 1. The front of the pressure relief pipe 7 is installed through the electric telescopic rod 8. When the electric energy is transmitted to the interior of the electric telescopic rod 8 via the electromagnetic relay 6, the electric telescopic rod 8 contracts, and drives the shielding block 10 to contract to the interior of the fixed plate 9.
