Description
Technical field
The utility model relates to a kind of valve, specifically a kind of clamping valve.
Background technique
Along with the development of science and technology and the progress of society, industrial level is more and more higher, and the requirement for the various parts of application is also more and more higher, and clamping valve is exactly wherein a kind of.Control the start-stop device connecting or block pipeline medium during clamping valve is applicable to, under the various pressure of small-bore pipeline, temperature and medium, be widely used in the fields such as water-treating equipment, chemical industry equipment, petrochemical equipment, oil equipment, papermaking equipment, winning equipment, power equipment be supporting.The blasting resistance structure precision of existing clamping valve is not high in the market, explosion-proof pressure tolerance is large, after long-time placement, explosion-proof pressure can exceed original standard to play elastic force pressure and ejection power inadequate, and tightness is unstable, and these are all that application in industry and production bring inconvenience.
Model utility content
The purpose of this utility model is to provide a kind of clamping valve, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of clamping valve, comprise valve base, explosion-proof push rod, explosion-proof cushion rubber and explosion-proof push rod spring, described explosion-proof push rod is arranged in valve base by explosion-proof push rod cushion rubber, the inside of explosion-proof push rod upper end is provided with groove, and explosion-proof push rod cushion rubber is stuck in groove, and explosion-proof push rod outside is provided with annular groove, explosion-proof cushion rubber is arranged in annular groove, explosion-proof push rod lower end cover have explosion-proof push rod spring, the internal diameter of explosion-proof push rod spring is greater than the external diameter of explosion-proof push rod lower end, explosion-proof push rod bottom explosion proof nut is installed.
As further program of the utility model: explosion-proof push rod and valve base adopt aluminum alloy material to make, explosion proof nut adopts zinc alloy material to make, and explosion-proof push rod spring adopts 65Mn material to make, and explosion-proof cushion rubber and explosion-proof push rod cushion rubber adopt butyronitrile material to make.
As further program of the utility model: the quantity of explosion-proof push rod, explosion-proof cushion rubber and explosion-proof push rod spring is one.
As further program of the utility model: explosion proof nut is hexagon nut.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, reasonable in design, easy for installation, quick, long service life; Explosion-proof push rod is provided with precompressed distance, plays elastic force pressure and tightness is more stable than existing clamping valve and accurate, and safety in utilization is good.

Fig. 2 is the sectional drawing of clamping valve.
Fig. 3 is the structural representation of explosion-proof push rod in clamping valve.
Fig. 4 is the structural representation of explosion-proof push rod cushion rubber in clamping valve.
Wherein: the explosion-proof push rod of 1-, 2-explosion proof nut, the explosion-proof push rod spring of 3-, the explosion-proof cushion rubber of 4-, the explosion-proof push rod cushion rubber of 5-, 6-valve base.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1-4, a kind of clamping valve, comprise valve base 6, explosion-proof push rod 1, explosion-proof cushion rubber 4 and explosion-proof push rod spring 3, described explosion-proof push rod 1 is arranged in valve base 6 by explosion-proof push rod cushion rubber 5, the inside of explosion-proof push rod 1 upper end is provided with groove, explosion-proof push rod cushion rubber 5 is stuck in groove, explosion-proof push rod 1 outside is provided with annular groove, explosion-proof cushion rubber 4 is arranged in annular groove, the lower end cover of explosion-proof push rod 1 has explosion-proof push rod spring 3, the internal diameter of explosion-proof push rod spring 3 is greater than the external diameter of explosion-proof push rod 1 lower end, explosion-proof push rod 1 explosion proof nut 2 is installed bottom.Explosion-proof push rod 1 and valve base 6 adopt aluminum alloy material to make, and explosion proof nut 2 adopts zinc alloy material to make, and explosion-proof push rod spring 3 adopts 65Mn material to make, and explosion-proof cushion rubber 4 and explosion-proof push rod cushion rubber 5 adopt butyronitrile material to make.The quantity of explosion-proof push rod 1, explosion-proof cushion rubber 4 and explosion-proof push rod spring 3 is one.Explosion proof nut 2 is hexagon nut.
Working principle of the present utility model is: the explosion-proof push rod 1 of this device is provided with precompressed distance, after this device is placed for a long time, can not by sealer compressive strain when explosion-proof push rod spring 3 presses down, and ensure elastic force pressure and bubble-tight stable.This apparatus structure is simple, reasonable in design, easy for installation, quick, long service life; Explosion-proof push rod 1 is provided with precompressed distance, plays elastic force pressure and tightness is more stable than existing clamping valve and accurate, and safety in utilization is good.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
