Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a stable anti-falling type valve. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Existing valves are connected to the pipes on both sides by bolts during installation. There is a lack of effective support and anti-falling structure. The valve is suspended off the ground. Under long-term use, the valve may fall and cause the connection to loosen.

[0003] A search of CN219472846U Chinese utility model patent discloses an anti-drop valve. This solution uses a clamping adjustment piece in conjunction with a clamping seat. The clamping seat can be used to clamp and support the pipes on both sides of the valve body, and the bottom plate can be used for fixed support, thereby effectively preventing the valve body from falling and causing the valve body to loosen and separate from the pipe. The sliding seat is used in conjunction with a slide rail ring, and the angle can be adaptively adjusted according to the inclination of the bottom plate mounting surface.

[0004] However, after research by the applicant, it was found that the scheme had the following problems. First, the scheme needed to be tightened and disassembled by means of screws and nuts, so the process was cumbersome and inconvenient to use. Secondly, the height adjustment of the valve body needed to be fixed by the vertical plate, the horizontal plate and the positioning bolts, so the adjustment process was complicated and the use efficiency was low. In response to this, we proposed a stable and anti-falling valve. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a stable anti-falling type valve.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A stable and anti-falling valve comprises a valve body, a fixed seat is welded to the bottom of the valve body, a telescopic rod is vertically arranged in the center of the bottom of the fixed seat, a base is arranged at the bottom of the telescopic rod, guide rails are symmetrically arranged at both ends of the top of the base, sliding seats are slidably sleeved on the top of the guide rails, connecting rods are hinged on the side of the sliding seat close to the telescopic rod, the end of the connecting rod away from the sliding seat is hinged to the bottom of the base, sliding rods are symmetrically inserted in the upper part of the sliding seat for sliding, and positioning components for fixing the height of the valve body are arranged on the end of the sliding rod away from the sliding seat.

[0008] Preferably, the positioning assembly includes a clamping block which is arranged at the end of the sliding rod away from the sliding seat, a serrated strip is provided on the side of the clamping block away from the sliding seat, the inclined surfaces of the serrated strip are slidably opposed to the inclined surfaces of the clamping blocks on the adjacent side, a top spring is provided at the position of the sliding rod close to the clamping block and the sliding seat, and a release assembly for controlling the synchronous movement of the clamping block is provided at the opposite end of the sliding rod on the adjacent side.

[0009] Through the above technical solution: the clamping block is used in conjunction with the serrated strip, the valve body can be fixed by pressing it, and it cannot slide in the opposite direction by itself, so that accurate height control can be obtained and the installation is easy.

[0010] Preferably, the release assembly includes racks that are transversely arranged at one end of the opposite surface of the sliding rod on the adjacent side, and the opposite surface of the racks on the adjacent side are meshed with the same gear. A spline rod is coaxially and transversely arranged at the center of the gear, and the spline rod is slidably sleeved with a spline sleeve. The outer peripheral surface of the spline sleeve is rotatably sleeved with a first support seat, and the first support seat is fixed to the top of the base. An adjustment assembly for controlling the rotation of the gear is provided at the end of the spline sleeve away from the gear.

[0011] Through the above technical solution: the spline rod is used to drive the gear to rotate, thereby driving the rack to slide synchronously, thereby separating the clamping block from the serrated strip, and the valve body can be quickly released to facilitate its rise control.

[0012] Furthermore, the adjustment assembly includes a second support seat symmetrically arranged on the top of the base, a rotating rod is inserted into the upper part of the second support seat for transverse rotation, both ends of the rotating rod and the end of the spline sleeve are sleeved with synchronous wheels, the synchronous wheels on the adjacent side are respectively sleeved with the same synchronous belt, and a knob is coaxially provided at the end of the rotating rod.

[0013] Through the above technical solution: the knob is used to rotate the rotating rod, and the spline sleeve and the spline rod are driven to rotate synchronously through the synchronous belt and the synchronous wheel, thereby playing a role of rapid adjustment and achieving rapid and synchronous release of the clamping block.

[0014] Furthermore, screws are vertically symmetrically arranged on both sides of the top of the base, and threaded sleeves are threadedly sleeved on the outer circumference of the screws, and the tops of the threaded sleeves are abutted against the bottom of the fixed seat.

[0015] Through the above technical solution: using the threaded sleeve in conjunction with the screw, when the valve body is installed, the threaded sleeve is rotated to make it rise straight up and abut against the bottom of the fixed seat, thereby forming an efficient support for the fixed seat and preventing the valve body from being affected by external forces and causing its position to change.

[0016] Preferably, a compression spring is sleeved on the outer circumference of the telescopic rod.

[0017] Through the above technical solution: the compression spring is used to make the valve body obtain an upward thrust, thereby preventing the valve body from being pressed down and causing a change in height position.

[0018] The beneficial effects of the utility model are:

[0019] 1. Through the positioning assembly, the clamping block is used in conjunction with the serrated strip. By pressing the valve body, the clamping block can be automatically retracted. When the pressure on the valve body stops, the compression spring is used to thrust the valve body upward, so that the valve body itself cannot slide in the opposite direction, thereby preventing the valve body from being pressed down and causing a change in height position. Accurate height control can be obtained, and the installation is easy at the same time.

[0020] 2. By using the adjustment component in conjunction with the release component, the spline rod is used to drive the gear to rotate, and then the rack is driven to slide synchronously, so that the clamping block is separated from the serrated strip, and the valve body can be quickly released to facilitate controlling its rise. In addition, the spline rod is used in conjunction with the spline sleeve, so that when the slide seat slides, the transmission of the spline rod will not be affected, and the valve body can be fixed at any height, which is very easy to install and can greatly improve the installation accuracy.

In order to more clearly understand the technical means of the utility model, it can be implemented in accordance with the contents of the specification.
