Description

Technical Field

[0001] The utility model relates to the field of silencing check valves, in particular to a pipeline silencing check valve. Background Art

[0002] A silencing check valve refers to a valve that automatically opens and closes the valve flap relying on the flow of the medium itself to prevent the reverse flow of the medium. It is also called a non-return valve, a one-way valve, a silencing check valve, a reverse flow valve, and a back pressure valve. A check valve belongs to an automatic valve, and its main functions are to prevent the reverse flow of the medium, prevent the pump and the driving motor from reversing, and the discharge of the medium in the container.

[0003] According to the disclosed patent 202322504430.4, a pipeline silencing check valve includes a silencing check valve body. A docking component is provided at the bottom of the silencing check valve body. The docking component includes: a docking seat; a bidirectional lead screw rotatably connected inside the docking seat; a crank fixedly connected to one end of the bidirectional lead screw; lead screw nuts symmetrically distributed on the outer sidewall of the bidirectional lead screw; and docking sliders fixedly connected to the tops of the lead screw nuts. By providing the docking component and the clamping component, the docking component can synchronously drive the two clamping components to move inward, so that the two clamping components can synchronously clamp the two ports of the silencing check valve body. This structure is simple and can quickly connect the silencing check valve. Only by turning the crank, the docking of the pipeline and the silencing check valve can be achieved, reducing the installation difficulty and operation steps, and greatly improving the installation efficiency of the silencing check valve. In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. Although by providing the docking component and the clamping component, the docking component can synchronously drive the two clamping components to move inward, so that the two clamping components can synchronously clamp the two ports of the silencing check valve body. This structure is simple and can quickly connect the silencing check valve. Only by turning the crank, the docking of the pipeline and the silencing check valve can be achieved, reducing the installation difficulty and operation steps, and greatly improving the installation efficiency of the silencing check valve. However, in the use process, for a traditional pipeline silencing check valve, a docking component needs to be additionally provided at the bottom of the valve body, resulting in a relatively large overall volume of the valve body. When the installation position is small, it is easy to cause the valve body to be unable to be installed. Moreover, by using threaded rods with opposite threads to drive the two clamping components to move at the same time, since the model sizes of the pipelines connected to both sides of the valve body are different, and the connection distances to the valve body are also different, when the two clamping components that move simultaneously are used for docking and clamping, there is a situation where the docking distances on both sides are different. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a pipeline silencing check valve, so as to solve the technical problems of the current traditional pipeline silencing check valve, which requires an additional docking component to be arranged at the bottom of the valve body, resulting in a relatively large overall volume of the valve body. When the installation position is small, it is easy to cause the valve body to be unable to be installed. Moreover, with threaded rods of opposite threads driving two clamping components to move simultaneously, due to the different model sizes and connection distances of the pipelines connected to both sides of the valve body, when the two clamping components moving simultaneously are used for docking and clamping, there is a situation where the docking distances on both sides are different.

[0005] In order to achieve the purpose of the present utility model, the technical solution adopted by the present utility model is as follows: Design a pipeline silencing check valve, including a valve body. A groove is opened at the bottom of the valve body. Installation grooves are opened on both sides inside the groove. A micro motor is installed inside the installation groove. One side of the micro motor is connected with a motor shaft. A moving component is arranged at the end of the motor shaft far away from the micro motor.

[0006] One end of an L-shaped rod body is fixed to the top of the moving component, driving the L-shaped rod body to move horizontally. The other end of the L-shaped rod body is fixed with a support ring.

[0007] Preferably, the moving component includes a threaded rod fixed on one side of the motor shaft, a moving block penetrated by the threaded rod outside, and an L-shaped rod body fixed on the top of the moving block. The screw hole in the moving block is threadedly connected with the threaded rod.

[0008] Preferably, a plurality of circular grooves are opened on the inner wall of the support ring, and a plurality of elastic telescopic members are installed inside the plurality of circular grooves.

[0009] Preferably, the elastic telescopic member includes a first fixed cylinder and a second fixed cylinder sleeved with each other. A spring is fixed between the first fixed cylinder and the second fixed cylinder sleeved with each other, and the second fixed cylinder is driven to move by the elastic force of the spring.

[0010] Preferably, a fixed block is fixed to the bottom of the valve body, and a liquid receiving shell is fixed to the bottom of the fixed block. Liquid inlet receiving grooves and liquid outlet receiving grooves are respectively opened on both sides of the top of the liquid receiving shell.

[0011] Preferably, one end of a micro liquid pump is communicated with the front end of the liquid inlet receiving groove, and the other end of the micro liquid pump is communicated with a conveying pipeline.

[0012] Preferably, the end of the conveying pipeline far away from the micro liquid pump is communicated with the valve body, and is used for conveying the medium leaked during liquid inlet into the valve body.

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

[0014] 1. By combining a micro motor, a moving block, and an L-shaped rod, the utility model can not only set the micro motor and the moving block on the top of the valve body, integrated with the valve body, without setting a mechanism outside the valve body, reducing the overall volume of the valve body. Moreover, due to the provision of two micro motors, the two micro motors can be used to drive the moving block and the L-shaped rod to move respectively, so as to adjust the support rings on both sides separately according to the connection distances of different pipes. In addition, a plurality of elastic telescopic members are provided on the inner wall of the support ring. When pipes of different sizes pass through the support ring, the elastic telescopic members can be used to tightly limit pipes of different sizes. This solves the technical problems of the traditional pipeline sound-absorbing check valve, which requires an additional docking component at the bottom of the valve body, resulting in a larger overall volume of the valve body. When the installation position is small, it is easy to cause the valve body to be unable to be installed. Moreover, by using threaded rods with opposite threads to drive two clamping components to move simultaneously, since the model sizes of the pipes connected to both sides of the valve body are different, and the connection distances to the valve body are also different, when the two clamping components move simultaneously, there is a situation where the docking distances on both sides are different during docking and clamping.

[0015] 2. By combining a liquid receiving housing, a micro liquid pump, and a conveying pipeline, the utility model can not only use the liquid inlet receiving groove and the liquid outlet receiving groove on the top of the liquid receiving housing to receive the media leaked from the liquid inlet position and the liquid outlet position of the valve body respectively, and collect the leaked media. Moreover, after the media at the liquid inlet position of the valve body leaks, the micro liquid pump can be used to pump the media leaked from the liquid inlet position of the valve body into the conveying pipeline and re-enter it into the valve body for conveying, directly bypassing the leaked liquid inlet position of the valve body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the utility model with reference to the drawings and embodiments:

[0021] Embodiment 1: A pipeline silencing check valve, see Figures 1 to 3 , including a valve body 1. A groove 2 is opened at the bottom of the valve body 1. Installation grooves 204 are opened on both sides inside the groove 2. A micro motor 205 is installed inside the installation groove 204. One side of the micro motor 205 is connected to a motor shaft 206. A moving component is arranged at the end of the motor shaft 206 away from the micro motor 205; One end of an L-shaped rod 201 is fixed to the top of the moving component, driving the L-shaped rod 201 to move horizontally. The other end of the L-shaped rod 201 is fixed to a support ring 202. First, pass the pipelines connected to both sides of the valve body 1 through the support rings 202 on both sides. After the pipelines pass through the inside of the support rings 202, turn on the two micro motors 205 in the groove 2 respectively. The micro motor 205 drives the motor shaft 206, the motor shaft 206 drives a threaded rod 207, and the threaded rod 207 is used to drive a moving block 203 to move. The moving block 203 will drive the L-shaped rod 201 to move, the L-shaped rod 201 will drive the support ring 202 to move, and the support ring 202 drives the pipeline to be butted with the valve body 1. According to the connection distances of different pipelines, the support rings 202 on both sides are adjusted separately, solving the problem of the traditional pipeline silencing check valve that an additional butting component needs to be arranged at the bottom of the valve body 1, resulting in a relatively large overall volume of the valve body 1. When the installation position is small, it is easy to cause the valve body 1 to be unable to be installed. Moreover, by using threaded rods 207 with opposite threads to drive two clamping components to move simultaneously, since the model sizes of the pipelines connected to both sides of the valve body 1 are different and the connection distances to the valve body 1 are also different, when the two simultaneously moving clamping components are butting and clamping, there is a situation where the butting distances on both sides are different.

[0022] Specifically, see Figure 2 , the moving component includes a threaded rod 207 fixed to one side of the motor shaft 206, a moving block 203 penetrated by the outside of the threaded rod 207, and an L-shaped rod 201 fixed to the top of the moving block 203. The threaded hole in the moving block 203 is threadedly connected to the threaded rod 207.

[0023] Furthermore, see Figure 1 , a plurality of circular grooves 209 are opened on the inner wall of the support ring 202. A plurality of elastic telescopic members are installed inside the plurality of circular grooves 209. By arranging a plurality of elastic telescopic members on the inner wall of the support ring 202, when pipelines of different sizes pass through the support ring 202, the elasticity of a spring 208 can be utilized to drive a second fixing cylinder 211 to move, and the second fixing cylinder 211 is used to tightly limit pipelines of different sizes.

[0024] It should be noted that, see Figure 3, the elastic telescopic member includes a first fixed cylinder 210 and a second fixed cylinder 211 that are sleeved with each other. A spring 208 is fixed between the first fixed cylinder 210 and the second fixed cylinder 211 that are sleeved with each other. The elastic force of the spring 208 is used to drive the second fixed cylinder 211 to move.

[0025] It should be noted that, referring to Figure 1 , a fixed block 3 is fixed to the bottom of the valve body 1, and a liquid receiving housing 301 is fixed to the bottom of the fixed block 3. Liquid inlet receiving grooves 302 and liquid outlet receiving grooves 303 are respectively formed on both sides of the top of the liquid receiving housing 301.

[0026] It is worth introducing that, referring to Figure 1 , one end of a micro liquid pump 304 is connected to the front end of the liquid inlet receiving groove 302, and the other end of the micro liquid pump 304 is connected to a delivery pipeline 305. By using the liquid inlet receiving groove 302 and the liquid outlet receiving groove 303 on the top of the liquid receiving housing 301, the media leaked from the liquid inlet position and the liquid outlet position of the valve body 1 can be respectively received to collect the leaked media. Moreover, after the media at the liquid inlet position of the valve body 1 leaks, the micro liquid pump 304 can be turned on to pump out the media leaked from the liquid inlet position of the valve body 1 and input it into the delivery pipeline 305. The media is re-input into the valve body 1 through the delivery pipeline 305, directly bypassing the leaked liquid inlet position of the valve body 1.

[0027] It should be emphasized that, referring to Figure 1 , one end of the delivery pipeline 305 far from the micro liquid pump 304 is connected to the valve body 1, for delivering the media leaked during liquid inlet to the inside of the valve body 1.

[0028] When using a pipeline silencing check valve, first pass the pipelines connected to both sides of the valve body 1 through the support rings 202 on both sides. After the pipelines pass through the inside of the support rings 202, turn on the two micro-motors 205 in the grooves 2 respectively. The micro-motors 205 drive the motor shafts 206, and the motor shafts 206 drive the threaded rods 207 to rotate. The threaded rods 207 are used to drive the moving blocks 203 to move. The moving blocks 203 will drive the L-shaped rod bodies 201 to move. The L-shaped rod bodies 201 separately drive the support rings 202 on both sides to adjust and move according to the connection distances of different pipelines. The support rings 202 drive the pipelines to be butted with the valve body 1. Since a plurality of elastic telescopic members are provided on the inner wall of the support rings 202, when pipelines of different sizes pass through the support rings 202, the elastic force of the springs 208 can be used to drive the second fixed cylinders 211 to move, and the second fixed cylinders 211 are used to tightly limit pipelines of different sizes. The liquid inlet liquid receiving groove 302 and the liquid outlet liquid receiving groove 303 at the top of the liquid receiving shell 301 can respectively catch the media leaked from the liquid inlet position and the liquid outlet position of the valve body 1 to collect the leaked media. Moreover, after the media at the liquid inlet position of the valve body 1 leaks, the micro liquid pump 304 can be turned on to pump out the media leaked from the liquid inlet position of the valve body 1 and input it into the conveying pipeline 305. The media is re-input into the valve body 1 through the conveying pipeline 305, directly bypassing the leaked liquid inlet position of the valve body 1.

However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
