Description

Technical Field

[0001] This utility model relates to the field of solenoid valves, and in particular to a remote control regulating valve. Background Technology

[0002] A solenoid valve is a basic automated actuator that uses electromagnetic force to control the on / off state or direction of fluids (liquids, gases, oils, etc.). It is commonly used in industrial control systems to adjust the direction, flow rate, and other parameters of the medium. By connecting the solenoid valve to a control circuit, remote control and regulation of pipeline fluids can be achieved.

[0003] When water freezes in low-temperature environments, the volume collisions cause an increase in the internal pressure of the pipeline. The pressure has nowhere to be released and will act on the valve stem and plunger, causing damage to the components (see the background technology of an actuation pressure relief mechanism for an antifreeze solenoid valve in announcement number CN222992182U). This not only affects the normal operation of the subsequent solenoid valve, but also easily leads to the solenoid valve freezing and cracking. The purpose of this utility model is to improve the existing solenoid valve structure to solve the above problems and reduce the damage rate of solenoid valves in low-temperature environments. Utility Model Content

[0004] The purpose of this invention is to provide a remote control regulating valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, a valve body, a telescopic rod, an upper bolt, and a lower bolt. The housing and valve body are connected. The valve body contains components such as an electromagnet for attracting the valve stem. In specific implementations, the valve body can be connected to the control device via wire or wireless connection according to actual needs, without substantially affecting the technical effect. Mounting flanges are formed on the connecting surfaces of the housing and valve body. A plunger is provided at the bottom end of the valve stem of the valve body, which can cooperate with the valve seat inside the housing. Mounting grooves are formed on the opposite surfaces of the mounting flanges. The telescopic rod is located within the mounting groove, with both ends connected to the mounting flanges. The telescopic rod refers to… The component in question is a telescopic rod-shaped part, which is known to those skilled in the art. Therefore, its specific structure and working principle will not be further explained. The upper and lower bolts are respectively set on the mounting flanges of the valve body and the housing. The lower bolt has a screw hole that can mate with the upper bolt. Both the upper and lower bolts are made of plastic. The specific type of plastic material used is not the technical content that the applicant wants to protect, so it will not be further disclosed. In specific implementation, technicians can change the disconnection threshold by changing the material and specifications of the upper and lower bolts to suit different types of application scenarios.

[0006] To optimize the above technical solution, further measures are taken, including a connecting rod and a baffle plate. A cavity is formed inside the valve stem, and a limiting block is formed at the top of the connecting rod, which forms a sliding pair along the length of the valve stem. The baffle plate is connected to the bottom of the connecting rod and can cooperate with the valve seat. When the valve body is separated from the housing, the valve stem and valve body move synchronously, and the baffle plate will move upward synchronously under the drive of the connecting rod located inside the valve body, thus blocking the valve seat.

[0007] As a further improvement to the above technical solution: a first annular locking block is formed on the top surface of the water baffle, and a first annular limiting groove is formed on the bottom surface of the valve seat. The first limiting groove can cooperate with the first annular locking block. The cooperation of the first limiting groove and the second limiting groove ensures that the top surface of the water baffle can stably cooperate with the bottom surface of the valve seat, thereby preventing the water baffle from shifting.

[0008] As a further improvement to the technical solution: a second annular locking block is formed on the bottom surface of the baffle plate, and a second limiting groove is formed inside the housing. The second limiting groove can cooperate with the second annular locking block. Through the cooperation of the second annular locking block and the second limiting groove, it is ensured that the baffle plate can be stably connected to the housing under normal conditions, so as to prevent the baffle plate from blocking the valve seat during fluid transportation.

[0009] As an improvement to the aforementioned technical solution, a sealing gasket is also included. The sealing gasket is placed between the mounting flanges to improve the sealing performance between the mounting flanges and prevent leakage. The sealing gasket is made of an elastic material. The specific type of elastic material used is not the technical content that the applicant intends to protect. In specific implementation, technicians can select different types of elastic materials according to actual needs, which will not have a substantial impact on the technical effect.

[0010] Furthermore, it also includes an elastic protective membrane, which is connected to the mounting flange on the connecting surface of the housing and the valve body. The elastic protective membrane refers to a membrane-like component made of elastic material that plays a protective role. The elastic material is existing technology and will not be described further. Its function is to protect the upper and lower bolts, reduce the exposure of the upper and lower bolts to prevent them from aging in the air, and extend their service life.

[0011] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model provides a remote control regulating valve. When the pipeline pressure increases due to icing, the valve body and the mounting flange of the housing can be separated to protect the valve stem and plunger from damage. At the same time, the pressure can be released to the separation point of the mounting flange, which helps to ensure the service life and avoid valve damage caused by icing. It has practical significance and promotion value, and is expected to generate good economic benefits. Attached Figure Description

[0015] The sealing gasket 8 is installed between the mounting flanges 101.

[0016] The elastic protective membrane 9 is connected to the mounting flange 101 on the connecting surface of the housing 1 and the valve body 2.

The housing 1 and the valve body 2 are connected, and mounting flanges 101 are formed on the connecting surfaces of the housing 1 and the valve body 2. A plunger 202 is provided at the bottom end of the valve stem 201 of the valve body 2, and the plunger 202 can cooperate with the valve seat 102 inside the housing 1. The mounting flange 101 forms a mounting groove 103 on its opposite surfaces, and the telescopic rod 3 is located in the mounting groove 103 with its two ends connected to the mounting flange 101 respectively. The upper bolt 4 and the lower bolt 5 are respectively installed on the mounting flange 101 of the valve body 2 and the housing 1. The lower bolt 5 has a screw hole 501 that can cooperate with the upper bolt 4. Both the upper bolt 4 and the lower bolt 5 are made of plastic.

[0018] The sealing gasket 8 is installed between the mounting flanges 101.

[0019] The elastic protective membrane 9 is connected to the mounting flange 101 on the connecting surface of the housing 1 and the valve body 2.

[0020] A cavity 203 is formed inside the valve stem 201, and a limit block 601 is formed at the top of the connecting rod 6, which is located inside the cavity 203 and forms a moving pair with the cavity 203 along the length direction of the valve stem 201. The water baffle 7 is connected to the bottom end of the connecting rod 6. The water baffle 7 can cooperate with the valve seat 102. A first annular locking block 701 is formed on the top surface of the water baffle 7. A first annular limiting groove 702 is formed on the bottom surface of the valve seat 102.

[0021] Working principle: In actual use, the housing 1 is connected to the pipeline. For embodiments 1 and 2, when the water in the pipeline gradually freezes, the pressure inside the pipeline increases. The pressure acting on the valve body 2 exceeds the force threshold of the upper bolt 4 or the lower bolt 5. At this time, the upper bolt 4 / lower bolt 5 breaks, causing the telescopic rod 3 to extend and the mounting flange 101 to separate. The valve body 2 then moves upward, causing the valve stem 201 and plunger 202 to move outward synchronously, which helps to prevent the valve stem 201 and plunger 202 from being squeezed and damaged. At the same time, the pipeline pressure can be released to the mounting flange 101. When connecting the housing 1 and valve body 2 in the future, only the upper bolt 4 and lower bolt 5 need to be replaced to reinstall the housing 1 and valve body 2.

[0022] In Embodiment 2, under normal conditions, the limiting block 601 moves within the cavity 203 during the movement of the valve stem 201, without affecting the normal operation of the valve stem 201. When the upper bolt 4 / lower bolt 5 breaks, causing the valve body 2 to move outward, the valve stem 201 moves outward synchronously, driving the limiting block 601. At this time, the limiting block 601 drives the baffle plate 7 to seal the valve seat 102 through the connecting rod 6, which helps to reduce leakage.

[0023] The control method of this utility model is to achieve automatic control through an external controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
