Abstract

The utility model relates to the technical field of valve body parts, in particular to a vacuum valve bonnet with a flap handle. The bonnet (1) is hollow, a pair of second pin holes (1-1) corresponds to a pair of first pin holes (2-1), pins (4) are disposed in the second pin holes (1-1) and the first pin holes (2-1), a flap (2) is rotatably disposed on the bonnet (1) through the pins (4), a ball plunger (5) is connected to a threaded hole (2-2) in a threaded manner and matched with an annular V-shaped groove (1-2), and the handle (3) is welded on the flap (2). The handle can be hidden in the bonnet completely, and the application requirements of specific occasions can be met.

Description

Vacuum valve valve gap with turnover panel handle

Technical field:

The utility model relates to valve body component technical field, be specifically related to a kind of in vacuum system the supporting vacuum valve valve gap with turnover panel handle of the socket valve of pipe end setting.

Background technique:

The valve gap of vacuum valve needs frequent opening, and the vacuum valve valve gap that uses at present is fixed, and the above is provided with handle, and handle can protrude, a lot of bad uses of occasion.

The model utility content:

The purpose of this utility model is to provide a kind of vacuum valve valve gap with turnover panel handle, and it can be hidden in handle the inside of valve gap fully, can satisfy the usage requirement of particular place.

in order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises valve gap 1, turnover panel 2, handle 3, bearing pin 4 and elasticity positioning bead 5, valve gap 1 is the hollow setting, and be provided with a pair of the second pin shaft hole 1-1 and ring-type V-shaped groove 1-2 on valve gap 1, be provided with a pair of first pin shaft hole 2-1 corresponding with the second pin shaft hole 1-1 on turnover panel 2, be provided with a pair of tapped hole 2-2 with the shaft axis Vertical direction of a pair of the first pin shaft hole 2-1, a pair of the second pin shaft hole 1-1 is corresponding with a pair of the first pin shaft hole 2-1, the second pin shaft hole 1-1 and the first pin shaft hole 2-1 inside are provided with bearing pin 4, turnover panel 2 is arranged on valve gap 1 by bearing pin 4 is rotatable, positioning bead 5 is threaded with tapped hole 2-2, and positioning bead 5 coordinates with ring-type V-shaped groove 1-2, handle 3 is welded on turnover panel 2.

The utlity model has following beneficial effect: it can be hidden in handle the inside of valve gap fully, can satisfy the usage requirement of particular place.

Embodiment:

referring to Fig. 1-9, this embodiment by the following technical solutions: it comprises valve gap 1, turnover panel 2, handle 3, bearing pin 4 and elasticity positioning bead 5, valve gap 1 is the hollow setting, and be provided with a pair of the second pin shaft hole 1-1 and ring-type V-shaped groove 1-2 on valve gap 1, be provided with a pair of first pin shaft hole 2-1 corresponding with the second pin shaft hole 1-1 on turnover panel 2, be provided with a pair of tapped hole 2-2 with the shaft axis Vertical direction of a pair of the first pin shaft hole 2-1, a pair of the second pin shaft hole 1-1 is corresponding with a pair of the first pin shaft hole 2-1, the second pin shaft hole 1-1 and the first pin shaft hole 2-1 inside are provided with bearing pin 4, turnover panel 2 is arranged on valve gap 1 by bearing pin 4 is rotatable, positioning bead 5 is threaded with tapped hole 2-2, and positioning bead 5 coordinates with ring-type V-shaped groove 1-2, handle 3 is welded on turnover panel 2.

in this embodiment when guaranteeing valve gap and valve body effectively coordinate, valve gap is designed to the shape of hollow, the space of turnover panel and handle is provided, simultaneously, the internal surface of valve gap in the sustained height Position Design ring-type V-shaped groove and two pin shaft holes of bearing pin are installed, V-shaped groove coordinates with the elasticity positioning bead, formed the position structure with two position locations, in stable condition when two positions have guaranteed that handle is in up or down, and two pin shaft holes coordinate with two pin shaft holes on turnover panel, the center in four holes is on same shaft core line, after in the hole, a bearing pin being installed, formed between turnover panel and valve gap along the structural type of bearing pin center relative rotation motion of driving system, above-mentioned feature has jointly formed the turnover panel handle and has passed through along the bearing pin central rotation, reach and make the valve gap that himself is hidden in hollow inner, the final turnover panel handle that forms, valve gap, valve body three's upper plane is in the effect in same plane.

This embodiment can be hidden in handle the inside of valve gap fully, can satisfy the usage requirement of particular place.
