Abstract

The utility model discloses a pressing cover with a sealing ring for a static ring base. The pressing cover comprises a flange, a groove and a thread; and a sealing ring is sleeved on the groove. The sealing ring is an O-shaped; the internal diameter size of the sealing ring is more than the groove bottom size of the groove, and is less than the external diameter size of the thread. The pressing cover with the sealing ring for the static ring base provided by the utility model has a simple structure; the assembly accuracy and the reliable using property can be ensured; and the risk of losing or neglected loading of the O-shaped sealing ring in dismounting and mounting processes can be avoided. Meanwhile, the working amount in the dismounting process further can be reduced; a sealing effect is good; and the pressing cover is matched with a pump body of a water pump, and is applicable to a body of a part in need of being sealed in industries.

Description

A kind of stationary seat gland with seal ring

Technical field

The utility model relates to a kind of mechanical sealing element and uses the stationary seat gland, particularly a kind of stationary seat gland with seal ring.

Background technique

The hole structure Sealing of existing pump body adopts the installation of stationary seat gland and seal ring to guarantee its sealability usually.During assembling seal ring placed the groove of pump body, then with being threaded in the pump body of stationary seat gland, the internal thread in the pump body cooperates the mode with screwed that seal ring is compressed to get final product with the outside thread of stationary seat gland.The shortcoming that this sealing configuration exists is: 1, seal ring needs independent installation, and mechanical sealing element is defective need to be prone to seal ring is lost or neglected loading during repeated disassembled and assembled, thereby causes sealability to lose efficacy; 2, all need seal ring aimed at every turn and insert the stationary seat gland again after pump body platform hole places and tighten, installation procedure is complicated, wastes time and energy.

The model utility content

The utility model is the defective that exists in the above existing technology in order to overcome, and a kind of stationary seat gland of improved band seal ring is provided, and comprising: flange, groove, screw thread are with seal ring on its further groove.

In technique scheme, seal ring is O shape circle.

In technique scheme, the internal diameter of the seal ring size is greater than the bottom land size of groove and less than the outside dimension of screw thread.

Compared with prior art; The utlity model has following beneficial effect: because stationary seat gland and pump body are when tightening; The groove of stationary seat gland is just in time corresponding with the platform hole of pump body; Therefore consider at groove suit seal ring, and utilize the bottom land size of groove and, the internal diameter of seal ring is designed to greater than the bottom land size of groove and less than the outside dimension of screw thread less than the characteristics of the outside dimension of screw thread; Both can avoid internal diameter of the seal ring excessive, also avoid the internal diameter of the seal ring tension quilt corner wear problems of square thread down by deviating from the groove.And its sealing effect installation results compared with before-improvement will be got well; Stopped losing or the risk of neglected loading of seal ring in dismounting and the installation process; Also reduced simultaneously the workload in the disassembly process, main is the reliability that has guaranteed correctness, convenience and the usability of assembling.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model structure assembling schematic representation.

In conjunction with the accompanying drawing following reference character of mark above that:

1-stationary seat gland; The 2-seal ring; The 3-pump body; The 11-flange; The 12-groove; The 13-screw thread; 31-platform hole.

Embodiment

Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.

The utility model is as shown in Figure 1, and this stationary seat gland 1 comprises flange 11, groove 12, screw thread 13, is with seal ring 2 on its further groove 12.

Further as shown in Figure 2; During assembling; Stationary seat gland 1 directly inserts in the pump body 3, rotates stationary seat gland 1 then, and screw thread 13 outsides of stationary seat gland 1 and inboard cooperation of the screw thread of pump body 3 are tightened; Seal ring 2 is displaced downwardly to 31 places, platform hole and compacted thereupon, thereby reaches seal action.

More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.

Claims

1. stationary seat gland with seal ring, comprising: flange, groove, screw thread are with seal ring on its further groove.

2. a kind of stationary seat gland with seal ring according to claim 1 is characterized in that: said seal ring is O shape circle.
