Description
Technical Field
The invention belongs to an installation tool, and particularly relates to a small-caliber upper-mounting type ball valve seat installation tool.
Background
The small-caliber top-mounted ball valve cannot apply pre-tightening force to a valve seat to overcome a disc spring in the whole assembly process due to small space of a valve cavity and a flow passage, compact structure and the like, so that the valve seat cannot reach the specified mounting position of the valve body,
in view of the above, how to develop the research on the valve seat installation process under the premise of utilizing the existing valve structure and space is the first problem faced by the complete machine assembly of the small-caliber top-mounted ball valve.
Disclosure of Invention
The invention provides a small-caliber upper-mounting type ball valve seat mounting tool aiming at the defects of the prior art.
The technical scheme of the invention is as follows: the utility model provides a small-bore upper assembling type ball valve seat installation frock, wherein, including the tight cover that expands, the tight cover that expands is hollow cylinder part, sets up the tight screw rod that expands that is hollow cylinder equally in the middle of the tight cover that expands, sets up the tight dabber that expands in the tight screw rod that expands, sets up the tight nut that expands at the tight cover that expands foremost, connects tight nut at the tight cover overcoat that expands.
According to the installation tool for the small-caliber upper-mounting type ball valve seat, a friction gasket is arranged at the rear part of the expansion nut.
According to the installation tool for the small-caliber upper-mounted ball valve seat, the expansion sleeve is further sleeved with the adjusting gasket.
The installation tool for the small-caliber upper-mounting type ball valve seat is characterized in that the outer section of the expansion sleeve is of a hexagonal structure.
The installation tool for the small-caliber upper-mounting type ball valve seat is characterized in that a positioning shoulder is arranged in the middle of the expansion sleeve.
The invention has the following effects: (1) the structure is ingenious and the operation is easy. Due to the adoption of the combined unit structure, the structure is ingenious, the whole weight is light, and the carrying by installation personnel is convenient. Simultaneously, the expansion sleeve has the functions of automation and valve seat positioning and centering, so that the device can be quickly installed when in use. (2) The tool has strong universality. Because the cover that expands possesses certain elasticity, the cover that expands simultaneously adopts taper fit with the tight dabber cooperation that expands, can realize the tight that expands of this frock in the certain limit through taut tight dabber that expands, so this frock has stronger commonality. (3) Reduce operating personnel working strength, improve work efficiency. In order to reduce the friction force between the nut and the part in the expansion process, friction gaskets are respectively added between the nut and the part to reduce the working strength of operators and improve the working efficiency.

Detailed Description
This patent is further described below with reference to the accompanying drawings:
as shown in fig. 1 and 2, 4 elastic grooves are formed at the left end of the expansion sleeve 3, so that the expansion sleeve has elasticity. In order to provide the tensioning reaction force for the expansion sleeve 3, an outer hexagonal structure is arranged at the right end part of the expansion sleeve. Meanwhile, the installation is convenient and fast, and a positioning shoulder is arranged in the middle of the expansion sleeve 3. Utilize the tight dabber 1 that expands and the tight taper fit between the cover 3 that expands, adopt the tight screw rod 2 that expands to connect the tight nut 7 that expands simultaneously, make it become an organic whole, through the tight nut 7 that expands of screwing, under the tight screw rod 2 pulling force effect that expands, can realize the tight cover 3 left end face stabilizer blades that expand and open to the tight function that expands is realized.
In order to guarantee the long service life of the device and the tightening strength of the nut, an adjusting gasket 4 is respectively added between the tightening nut 5 and the part to be installed, and a friction gasket 6 is added between the expansion nut 7 and the expansion sleeve 3, so that the situation that the clamping is caused by overlarge friction force in the tightening process is avoided.
As shown in fig. 4 and 5, after the valve seat 8 and the disc spring 9 are preassembled in the inner hole of the upper-mounted valve body 10, then the device unit is arranged into a preset position through a hole at the right end face of the upper-mounted valve body 10, the positioning shoulder of the expansion sleeve 3 is positioned with the inner hole of the upper-mounted valve body 10 to ensure that the device is concentric with the valve seat 8, after the installation is finished, the expansion sleeve 3 is fixed by a wrench 11, by screwing the expansion nut 7 (forming a reaction force with the wrench 11), the legs of the expansion sleeve 3 are expanded to the groove of the valve seat 8 and clamp the valve seat 8, then tighten tensioning nut 5 (and spanner 11 between form reaction force), make this device turn right side direction and remove to 9 pretightning forces of dish spring to assigned position are overcome to accurate steady drive disk seat 8, treat to install all the other assembly parts after, loosen the tight nut 7 that expands, can take out this device, the disk seat installation of quick completion.
