Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and in particular to a positioning mechanism and its manual throttle valve. Background Technology

[0002] A manual throttle valve is a type of valve used to control the flow rate of fluids. The valve opening is adjusted manually to change the flow rate or pressure of the fluid.

[0003] Traditional manual throttle valves regulate flow by turning a handle located on top of the valve. When repairing equipment or replacing parts, the throttle valve needs to be closed to prevent fluid from continuing to flow, thus ensuring the safety of maintenance personnel. However, when the pressure of the fluid in the pipeline fluctuates, the impact of the water flow causes the valve body to shake, which may cause the handle to shake, thereby opening the throttle valve and allowing the fluid in the pipeline to continue to flow. Therefore, this solution proposes a positioning mechanism and its manual throttle valve to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a positioning mechanism and its manual throttle valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism, characterized in that it comprises:

[0009] A positioning component is disposed at the bottom of the support base, and the positioning component is used to fix the position of the positioning base.

[0010] Preferably, the limiting component includes:

[0011] A sliding block, which is fixedly connected to the bottom of the support base;

[0012] A fixing block is provided at the bottom of the support base, and a sliding hole is provided in the middle of the fixing block. The sliding block is inserted into the interior of the sliding hole.

[0013] Preferably, the positioning component includes:

[0014] A locking block, wherein the locking block is inserted and connected to one side of the sliding block, and a pushing member is provided on one side of the locking block;

[0015] A locking hole is formed on the inner wall of one side of the sliding hole, and the locking block is inserted into the inside of the locking hole.

[0016] Preferably, the pushing member includes:

[0017] A push block, which is fixedly connected to one side of the locking block;

[0018] An elastic block is fixedly connected to one side of the push block.

[0019] Preferably, the bottom of the sliding block has a cavity, the pushing block is inserted into the cavity, the elastic block is fixedly connected to the inner wall of one side of the cavity, and a guide is provided at the connection between the pushing block and the cavity.

[0020] Preferably, the guide includes multiple positioning rods fixedly connected between the inner walls on both sides of the cavity, and multiple positioning holes are opened on one side of the push block, with the multiple positioning rods respectively inserted and connected inside the multiple positioning holes.

[0021] A manual throttle valve includes the aforementioned positioning mechanism and a valve body, which is fixedly connected to one side of a fixed block.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] This invention, through the design of a positioning seat, positioning groove, support seat, limiting component, and positioning component, allows the positioning seat to be moved after the throttle valve is closed, so that the handle of the throttle valve is inserted into the positioning groove on the positioning seat. The positioning component then fixes the position of the positioning seat. The positioning block, which is fixed in position, prevents the handle of the throttle valve from rotating, thus avoiding the situation where liquid is still flowing in the pipeline when the equipment is being repaired or parts are being replaced.
