Description

TECHNICAL FIELD

[0001] The utility model relates to the field of stop valve installation, specifically is a stop valve high support. BACKGROUND

[0002] As a common type of valve, stop valves play a crucial role in fluid control systems, often used to shut off or regulate fluid flow in pipelines. However, in practical applications, the installation position of the stop valve needs to be adapted to the height of the pipeline.

[0003] Chinese patent application No. 202420320617.0 discloses a stop valve high support, which sets several groups of U-shaped support frames and collars at the bottom end of the pipeline to lift the pipeline, and adjusts the height of the threaded shaft according to different road surface heights, thereby achieving the leveling of the two ends of the pipeline. When fixing a longer pipeline, the problem of bending of the longer pipeline is avoided. However, the height adjustment of this high support is relatively cumbersome, and only the height of one end of the stop valve can be adjusted, which cannot adapt to the installation of higher pipelines. SUMMARY

[0004] To overcome the above-mentioned shortcomings, the utility model provides a stop valve high support.

[0007] The utility model has the advantages of:

[0008] The utility model discloses a shake handle can be easily adjusted the height of stop valve, make it adapt to different installation demand, convenient and fast operation, adopt four lower fixed base and four upper fixed base and corresponding connecting rod mechanism, whole support structure is stable and reliable, can bear greater weight and pressure.

DETAILED DESCRIPTION

[0015] As Figures 1-5As shown: a stop valve frame high support, including the bottom plate 1, the bottom plate 1 has lifting plate 2, the bottom plate 1 top fixed connection four lower fixed seat 3, lifting plate 2 bottom four corners are fixedly connected with the upper fixed seat 4, upper fixed seat 4 is rectangular distribution, lower fixed seat 3 and upper fixed seat 4 corresponding, lower fixed seat 3 and upper fixed seat 4 are all by two vertical plate 5, two vertical plate 5 parallel interval arrangement, four lower fixed seat 3 top all have connecting rod one 6, connecting rod one 6 one end with lower fixed seat 3 two vertical plate 5 opposite side wall rotation connection, four upper fixed seat 4 bottom all have connecting rod two 7, connecting rod two 7 one end with upper fixed seat 4 two vertical plate 5 opposite side wall rotation connection, upper and lower corresponding connecting rod one 6 other end and connecting rod two 7 other end side wall between having connecting shaft 8, connecting shaft 8 through connecting rod one 6 and connecting rod two 7 side wall, connecting shaft 8 and connecting rod one 6 and connecting rod two 7 rotation connection, bottom plate 1 and lifting plate 2 between provided with two-way screw 9, two-way screw 9 left and right extension, two-way screw 9 left and right side outer wall are all screw nut 10, two ball nut 10 outer wall front and back side are all fixedly connected with the linkage rod 11 one end, linkage rod 11 other end and the proximal connecting shaft 8 end fixed connection, two-way screw 9 left end fixed connection crank 12, two-way screw 9 left end outer wall screw nut 13, locking nut 13 right side wall against the left ball nut 10 outer wall, lifting plate 2 top middle fixed connection fixed frame 14, stop valve 15 fixed installation in fixed frame 14 top.

[0016] In the initial state, the stop valve 15 is installed on the top of the lifting plate 2 through the fixed frame 14, and the lifting plate 2 is connected with the bottom plate 1 through a series of connecting rod mechanisms and the two-way screw 9, forming an adjustable height structure.

[0017] When the height of the stop valve 15 needs to be adjusted, the crank 12 located at the left end of the two-way screw 9 is shaken. Since the left and right outer walls of the two-way screw 9 are all threaded with the ball nut 10, and the moving directions of the two ball nuts 10 are opposite, that is, one moves left while the other moves right, therefore, shaking the crank 12 will cause the two ball nuts 10 to move in opposite directions at the same time.

[0018] With the movement of the ball nuts 10, they drive the connecting shaft 8 and its connected connecting rod one 6 and connecting rod two 7 to rotate through the linkage rod 11. Since the connecting rod one 6 and the connecting rod two 7 are connected to the four lower fixed seats 3 of the bottom plate 1 and the four upper fixed seats 4 of the lifting plate 2 respectively, this rotation will cause the lifting plate 2 to rise or fall relative to the bottom plate 1.

[0019] When the stop valve 15 reaches the desired height, the locking nut 13 can be tightened so that its right side wall abuts against the outer wall of the left ball nut 10, thereby locking the position of the two-way screw 9 and preventing the lifting plate 2 from moving accidentally.
