Abstract

The utility model provides a sphere which can be quickly dismounted, comprising a sphere body, a channel, a flat slot, etc. Two thread holes are drilled on a step on the upper part of the sphere. An eccentric distance L exists between the centerline of the channel and the centerline of the sphere. The utility model has the advantage of convenient disassembly of the sphere, which effectively raises working efficiency.

Description

A kind of spheroid

Affiliated technical field

The utility model relates to a kind of spheroid that is used for ball valve.

Background technique

The present upper-mounting type ball valve that uses of metallurgy, petrochemical industry, nuclear power industry, when seal ring is changed in maintenance owing to be interference fit between spheroid and the seal ring, so the taking-up spheroid is very difficult.

Summary of the invention

The deficiency that spheroid is taken out in inconvenience when keeping in repair in order to overcome existing upper-mounting type ball valve, the utility model provides a kind of spheroid of fast demountable.

The technological scheme that its technical problem that solves the utility model adopts is that a kind of spheroid is made up of ball body, passage, flat groove etc., is drilled with two tapped holes at spheroid upper step place, the center line of passage and throw of eccentric L of the center line of spheroid existence.

The beneficial effects of the utility model are that the spheroid dismounting is very convenient, have improved working efficiency effectively.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is embodiment's a plan view, is whole-cutaway view.

Fig. 2 is embodiment's a left view, is whole-cutaway view.

Fig. 3 is embodiment's a plan view.

Among the figure: 1. ball body; 2. tapped hole; 3. flat groove; 4. port hole.

Embodiment

As shown in Figure 1, 2, 3, be drilled with two tapped holes 2 on the step of ball body 1, there is a throw of eccentric L in the center line of the center line of port hole 4 and ball body 1, makes the passway form the inclined-plane.When dismounting, as long as be screwed into two lifting bolts, one shake gently at tapped hole 2 places, can take out spheroid easily.

Claims (1)

1, a kind of spheroid is made up of ball body, passage, flat groove etc., it is characterized in that: be drilled with two tapped holes at ball body upper step place, there are a throw of eccentric L in the center line of passage and the center line of spheroid.
