Abstract
The utility model discloses a taper line sealing device which comprises a nut, a valve body, a spring, a steel ball and a cone body, wherein the nut is connected to the valve body by screw threads; the cone body is clamped on the valve body; and the steel ball and the spring are installed in the valve body in a press fitting manner. With the tightening of the screw threads between the valve body and the nut, the cone body compresses the spring so that the steel ball is closely attached to a sealing surface of the inner chamber of the valve body under the pressure of the spring to implement spherical linear sealing between the steel ball and the sealing surface of the inner chamber of the valve body, simultaneously, along with the tightening of the screw threads between the valve body and the nut, the conical surface of the cone body is also hermetically attached to the valve body to generate another seal. In the structure for implementing spherical linear sealing between the steel ball and the sealing surface of the inner chamber of the valve body, when abrasion is caused between the steel ball and the sealing surface of the inner chamber of the valve body, the effects of regulation and compensation can be implemented by the pressure of the spring and the tightening of the screw threads between the valve body and the nut, and in a similar way, compensation effect is also implemented for the hermetical attachment between the conical surface of the cone body and the valve body according to the other seal.
Description
Technical field
The utility model relates to a kind of high-pressure grease pouring valve, relates in particular to a kind of tapering linear sealing device that is used for grease pouring valve.
Background technique
At present; The grease pouring valve of domestic production is the sealing of single sealing hard sphere, and the material that it is selected for use comprises and satisfied not the operating conditions at high pressure or rugged environment sealing life; Produced the phenomenon of " run, leak " grease; Do not have the lubrication of grease,, produced very big negative influence the valve use of integral body to whole valve.
Summary of the invention
For overcoming the defective of existing high-pressure grease pouring valve, the utility model provides a kind of tapering linear sealing device that is used for grease pouring valve.This grease pouring valve tapering linear sealing device can finely solve whole valve lubrication system and " run, leaked " problem.
The technical solution that the utility model adopted is:
A kind of tapering linear sealing device comprises nut, valve body, spring, steel ball, cone, and wherein nut is through being threaded on the valve body, and cone is installed on the valve body, and steel ball, spring are fitted in valve inner through cone.Along with tightening of the screw thread between valve body and the nut; The cone pressure spring is being fitted on the sealing surface of body cavity steel ball closely under the pressure of spring, realize the spherical line sealing at the sealing surface of steel ball and body cavity; Simultaneously; Cone is along with screw thread between valve body and the nut tightens, and the conical surface of cone has also been realized fitting with the sealing of valve body, produces another road sealing.
Realize in the spherical line sealing configuration at the sealing surface of described steel ball and body cavity; When wearing and tearing appear in the sealing surface of steel ball and body cavity; Through the pressure of spring and tightening of the screw thread between valve body and the nut, can work to regulate compensation, to its another road sealing; The conical surface of cone and the sealing of valve body are fitted, but also redeeming in like manner.
The usefulness of the utility model is:
When implementing the utility model; Steel ball is being fitted under the elastic force of spring on the sealing surface of body cavity closely, realizes inner sealing, and the conical surface of cone is fitted along with the sealing that has also realized with valve body of tightening of the screw thread of valve body; The blocked valve cavity pressure; Thereby realize the normal use of grease pouring valve,, have good seal performance to reach the purpose that prevents dielectric leakage; Beneficial effects such as long service life and compact structure, advantage such as safe and reliable are applicable to oil, chemical industry, pipeline upper ball valve, plate valve main accessories lubrication system grease pouring valve.
Description of drawings
Fig. 1 is the utility model section of structure.
Among Fig. 1: 1, nut, 2, valve body, 3, steel ball, 4, spring, 5, cone.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; A kind of tapering linear sealing of the utility model device comprises nut 1, valve body 2, steel ball 3, spring 4, cone 5, and wherein nut 1 is through being threaded on the valve body 2; Cone 5 is installed on the valve body 2, and steel ball 3, spring 4 are fitted in valve body 2 inside through cone 5.Along with tightening of screw thread between valve body 2 and the nut 1; Cone 5 pressure springs 4 are being fitted on the sealing surface of valve body 2 inner chambers steel ball 3 closely under the supporting force of spring 4, realize the spherical line sealing at the sealing surface of steel ball 3 and valve body 2 inner chambers; Simultaneously; Cone 5 is along with screw thread between valve body 2 and the nut 1 tightens, and the conical surface of cone 5 has also been realized fitting with the sealing of valve body 2, produces another road sealing of this device.
Realize in the spherical line sealing configuration at the sealing surface of described steel ball 3 and valve body 2 inner chambers; When wearing and tearing appear in the sealing surface of steel ball 3 and valve body 2 inner chambers; Through the supporting force of spring 4 and tightening of the screw thread between valve body 2 and the nut 1, can work to regulate compensation, to its another road sealing; The sealing of the conical surface of cone 5 and valve body 2 is fitted, but also redeeming in like manner.
