Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment, in particular to a self-constant pressure valve. Background Art

[0002] A constant pressure valve is a valve that can automatically adjust the flow and maintain a constant pressure. Its working principle is to control the flow through an adjustable valve core. When the pressure in the system changes, the valve core will automatically adjust its opening to keep the set pressure unchanged. There is also a horizontal valve body installed on the side of the valve body of the solenoid pilot valve, which is connected to the main valve as a whole and controls the opening and closing of the main valve together with the solenoid pilot valve. It is collectively called a constant pressure solenoid valve.

[0003] However, in the prior art, when the existing constant pressure solenoid valve is installed on the solenoid valve main pipeline, multiple bolts are usually used to stably fix the two together. However, this connection method is not convenient for disassembly and assembly of the constant pressure solenoid valve. During operation, the bolts need to be disassembled and assembled one by one, which is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: the installation and connection method through bolts is not convenient for disassembly and assembly of the constant pressure solenoid valve, and the bolts need to be disassembled and assembled one by one during operation, which is cumbersome, time-consuming and labor-intensive.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a self-constant pressure valve, including a solenoid valve main pipeline and a constant pressure solenoid valve, one end of the constant pressure solenoid valve is installed with a mounting disk, and a bolt is connected through the surface of the mounting disk, one end of the bolt is fixedly connected with a fixing ring, a guide rod is inserted and connected in the fixing ring, and one end of the guide rod is fixedly connected to the mounting disk, a circular hole is opened near the mounting port of the solenoid valve main pipeline, and a threaded pipe is rotatably connected in the circular hole, the threaded pipe is threadedly connected to the bolt, one end of the threaded pipe is fixedly connected with a gear, a rotating ring is rotatably connected at the outer edge of the mounting port of the solenoid valve main pipeline, and teeth are fixedly connected to one side of the rotating ring, and the teeth are meshed with the gear.

[0006] As a preferred embodiment, an anti-skid bump is fixedly connected to the outer surface of the rotating ring, and a plurality of anti-skid bumps are arranged equidistantly around the rotating ring.

[0007] As a preferred embodiment, a sliding block is slidably connected to the surface of the solenoid valve main pipeline above the anti-slip block, and a sliding ring is fixed to one side of the sliding block, a blocking plate is fixedly connected to the bottom of the sliding ring, and a number of blocking plates are equidistantly arranged.

[0008] As a preferred implementation, the width of the shift-blocking plate itself is consistent with the spacing length between the anti-slip bumps.

[0009] As a preferred implementation, a clamping plate is fixedly connected to the outer side of the main pipeline installation port of the solenoid valve, and one end of the clamping plate is clamped and connected to the sliding ring.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model rotates the rotating ring so that the teeth on the rotating ring drive the multiple gears to rotate together, thereby causing the multiple threaded tubes to rotate and drive the multiple bolts to move upward along the guide rod for disassembly. Conversely, the multiple bolts can be operated to install at the same time. In this way, when disassembling and assembling the constant pressure solenoid valve, there is no need to disassemble and assemble the bolts one by one, which is simple, quick and labor-saving.

[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] Example 1

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a self-constant pressure valve, including a solenoid valve main pipeline 1 and a constant pressure solenoid valve 2, one end of the constant pressure solenoid valve 2 is installed with a mounting plate 3, and the surface of the mounting plate 3 is penetrated with a bolt 4, the bolt 4 is used to fix the connection between the solenoid valve main pipeline 1 and the mounting plate 3, one end of the bolt 4 is fixedly connected with a fixing ring 5, the fixing ring 5 is interspersed with a guide rod 6, and one end of the guide rod 6 is fixedly connected to the mounting plate 3, with the help of the fixing ring 5 and the guide rod 6, the initial placement position of the bolt 4 is uniformly positioned, so that the thread direction on each bolt 4 is in the correct direction, which is convenient for each bolt 4 to be positioned later It can be installed downward in a unified manner. A circular hole is opened near the installation port of the solenoid valve main pipeline 1, and a threaded tube 7 is rotatably connected in the circular hole. The threaded tube 7 is threadedly connected to the bolt 4, and a gear 8 is fixedly connected to one end of the threaded tube 7. A rotating ring 9 is rotatably connected to the outer edge of the installation port of the solenoid valve main pipeline 1, and a tooth 10 is fixedly connected to one side of the rotating ring 9, and the tooth 10 is meshed with the gear 8. By rotating the rotating ring 9, the tooth 10 on the rotating ring drives multiple gears 8 to rotate together, thereby causing multiple threaded tubes 7 to rotate and drive multiple bolts 4 to move upward along the guide rod 6 for disassembly. Conversely, multiple bolts 4 can also be operated to install at the same time.

[0022] Example 2

[0023] like Figure 1-5As shown, the outer surface of the rotating ring 9 is fixedly connected with an anti-skid protrusion 11, and a number of anti-skid protrusions 11 are arranged equidistantly around the rotating ring 9. The anti-skid protrusions 11 are arranged to increase the friction force of the outer surface of the rotating ring 9, thereby achieving an anti-skid effect. The surface of the solenoid valve main pipeline 1 is slidably connected with a slider above the position of the anti-skid protrusion 11, and a sliding ring 12 is fixed to one side of the slider. A blocking plate 13 is fixedly connected to the bottom of the sliding ring 12, and a number of blocking plates 13 are equidistantly arranged. By sliding the sliding ring 12 downward to move the blocking plate 13 to a position between the anti-skid protrusions 11, a large range of rotation of the rotating ring 9 can be effectively avoided, and the bolt can be effectively improved. 4 is installed in the threaded tube 7 to ensure the stability of the connection between the solenoid valve main pipeline 1 and the mounting plate 3. The width of the blocking plate 13 itself is consistent with the distance between the anti-skid protrusions 11. In this way, when the blocking plate 13 moves between the anti-skid protrusions 11, it can completely fill the gap between the anti-skid protrusions 11, which can further ensure that the rotating ring 9 does not move. A clamping plate 14 is fixedly connected to the outer side of the mounting port of the solenoid valve main pipeline 1, and one end of the clamping plate 14 is clamped and connected with the sliding ring 12. Through the connection between the clamping plate 14 and the sliding ring 12, the sliding ring 12 can be suspended, so that the blocking plate 13 will not hinder the movement of the rotating ring 9 and affect the disassembly and assembly of the bolt 4.

[0024] Working principle:

[0025] like Figure 1-5 As shown, when the constant pressure solenoid valve 2 needs to be disassembled during use of the utility model, the user first lifts the sliding ring 12 upwards and engages it with the clamping plate 14 to disengage the shifting plate 13 from the position between the anti-slip protrusions 11, and then puts the hand on the anti-slip protrusions 11 and moves it to make the rotating ring 9 rotate. With the help of the teeth 10, the rotation of the rotating ring 9 drives the gear 8 and the threaded tube 7 to rotate. Under the rotation drive of the threaded tube 7, the bolt 4 and the fixing ring 5 move upward along the guide rod 6, and finally the bolt 4 is disengaged from the connection with the threaded tube 7, so that the constant pressure solenoid valve 2 and the mounting plate 3 can be easily removed from the solenoid valve main pipeline 1.
