Abstract
The utility model discloses a valve cover with a sealing groove. The valve cover comprises a valve cover body, wherein an annular sealing gasket groove is arranged on an annular installing surface at the bottom of the valve cover. After a sealing gasket is arranged in the sealing gasket groove, the sealing gasket groove is more tightly connected with a valve port part of a valve body, therefore, the sealing performance between the valve cover and the valve body is improved, and the quality of a regulating valve is ensured.
Description
Technical field:
The utility model relates generally to the part field on the modulating valve, relates in particular to a kind of valve gap with seal groove.
Background technique:
Modulating valve has another name called control valve, in industrial automation process control field, through accepting to regulate the control signal of control unit output, removes to change the final control unit of process parameters such as rate-of flow, pressure, temperature, liquid level by power operation.
Generally, the modulating valve structure includes valve body, has valve port on the valve body, is stamped valve gap on the valve port.Modulating valve in the course of the work, whether valve gap and valve body can be tightly connected the service behaviour that has influence on modulating valve.
In the prior art, the sealability that connects between valve gap and the valve body is relatively poor, influences the work of modulating valve, therefore, need improve the structure of valve gap.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of valve gap with seal groove to be provided, and it can improve the sealing that connects between valve gap and the valve body.
The utility model is realized through following technological scheme:
A kind of valve gap with seal groove is characterized in that: include the valve gap body, the attachment face of said valve gap body base circle is provided with the gasket slot of annular.
Described a kind of valve gap with seal groove is characterized in that: the sealing gasket that is mounted with annular in the said gasket slot.
The utility model has the advantages that:
After settling sealing gasket in the said gasket slot, be connected closelyr with the valve port position of valve body, improved the sealability between valve gap and the valve body, guaranteed the quality of modulating valve.
Description of drawings:
Fig. 1 is the structural representation at valve gap body attachment face position.
Embodiment:
Referring to accompanying drawing.
A kind of valve gap with seal groove includes valve gap body 1, and the attachment face of said valve gap body 1 base circle is provided with the gasket slot 2 of annular.Be mounted with the sealing gasket 3 of annular in the gasket slot 2.
Claims (1)
1. valve gap with seal groove is characterized in that: include the valve gap body, the attachment face of said valve gap body base circle is provided with the gasket slot of annular; Be mounted with the sealing gasket of annular in the said gasket slot.
