Abstract
The invention discloses a fire hydrant valve cover. The fire hydrant valve cover comprises a valve body and a valve cover, wherein the external thread of the valve body is matched with the internal thread of the valve cover; a circular sealing gasket is arranged between the end surface of the valve body and the inner bottom surface of the valve cover; the diameter of the circular sealing gasket is equal to the that of the inner end surface of the valve cover; a plurality of springs are arranged between the circular sealing gasket and the inner end surface of the valve cover. By adopting the structure that the circular sealing gasket is arranged between the valve body and the valve cover and the springs are arranged at the bottom of the circular sealing gasket, the airtightness of a fire hydrant can be effectively improved.
Description
Technical field
The present invention relates to fire-fighting domain, especially a kind of hydrant valve cap.
Background technology
Hydrant valve is the use of fire fighting truck water supply when fire extinguishing, hydrant valve cap is at ordinary times by being threaded on valve body, in order to guarantee sealing, hydrant valve cap must be tightened, in more existing fire hydrants in order to guarantee that sealing adopts rubber seal, but tighten for a long time and can cause rubber seal distortion due to valve gap, have a strong impact on the sealing of fire hydrant.
Summary of the invention
The present invention is directed to above-mentioned deficiency a kind of hydrant valve cap is provided, comprise valve body, valve gap, the external screw thread of described valve body matches with the internal thread of valve gap, be provided with round gasket between the end face of described valve body and valve gap inner bottom surface, the equal diameters of the diameter of described round gasket and valve gap internal end surface, be provided with many springs between the internal end surface of described round gasket and valve gap.
The invention has the beneficial effects as follows: by round gasket being set between valve body and valve gap and in the round gasket bottom, spring being set, can effectively improve the sealing of fire hydrant.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1-valve body, 2-valve gap, 3-round gasket, 4-spring as shown in the figure.
The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
A kind of hydrant valve cap as shown in Figure 1, comprise valve body 1, valve gap 2, the external screw thread of described valve body 1 matches with the internal thread of valve gap 2, be provided with round gasket 3 between the end face of described valve body 1 and valve gap inner bottom surface, the equal diameters of the diameter of described round gasket 3 and valve gap 1 internal end surface, be provided with many springs 4 between the internal end surface of described round gasket 3 and valve gap 1.The present invention, by round gasket being set between valve body and valve gap and in the round gasket bottom, spring being set, can effectively improve the sealing of fire hydrant.
The present invention is not limited to the aforesaid specific embodiment.The present invention expands to any new feature or any new combination disclosed in this manual, and the arbitrary new method disclosed or step or any new combination of process.
