Description
Technical field
The present invention relates to a kind of ball valve, specifically ultra-short ball valve.
Background technique
Because ultra-short ball valve has the advantages such as volume is little, quality is light, installation and maintenance are convenient, therefore in pharmacy and chemical plant installations, be usually applied to ultra-short ball valve.The valve rod of existing ultra-short ball valve is through valve body, in order to avoid valve in-vivo medium occurs leaking by the gap between valve rod and valve body, gap between valve rod and valve body is sealed by filler, ball valve can be completed disconnecting the conversion between connection by rotary valve rod during ultra-short ball valve work, easy to operate.But, in the process of rotary valve rod repeatedly, valve rod extruding filler repeatedly, sealing between valve rod and valve body is deteriorated, loaded down with trivial details because carrying out replacement operation process to the filler between valve rod and valve body, the direct abandoned of ultra-short ball valve that between existing a lot of valve rod and valve body, sealing configuration is damaged and no longer coming into operation, this just causes the wasting of resources.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide ultra-short ball valve easy to operate when the sealing configuration between valve body and valve rod is changed.
Object of the present invention is achieved through the following technical solutions: ultra-short ball valve, the driving mechanism comprising valve body, end cap, valve rod, spheroid and be connected with valve rod, described valve body is configured with spheroid chamber and connects the media outlet in spheroid chamber, described spheroid is arranged in spheroid chamber, described end cap is connected with valve body, and end cap is configured with the medium entrance connecting spheroid chamber; The top of described valve body is provided with groove, the through hole connecting this groove and spheroid chamber is provided with in valve body, the seal gasket mated with groove size is provided with in the groove of valve body, the other end that described valve rod connects driving mechanism end relatively through seal gasket and valve body through hole and be connected with spheroid, form interference fit between described seal gasket and valve rod.
Pad is provided with between described valve body and end cap.The present invention, by arranging pad between valve body and end cap, ensure the sealability between valve body and end cap, and pad can cushion the active force of end cap to valve body by the interaction energy of pad, and then ensures that the structure between valve body and end cap is not damaged.
Be bolted between described seal gasket and valve body.The present invention strengthens the linkage structure between seal gasket and valve body by bolt, seal gasket can be taken off by swivel bolt, easy to operate when this further makes the present invention change seal gasket.
The outlet end seal ring being provided with the entrance point seal ring be connected with end cap in described spheroid chamber and being connected with valve body, described spheroid contacts with outlet end seal ring with entrance point seal ring.The present invention passes through the effect of entrance point seal ring and outlet end seal ring, medium can be avoided from the clearance leakage between spheroid and end cap or valve body, and then enhance sealability of the present invention.
Compared with prior art, the present invention has following beneficial effect: the present invention includes valve body, end cap, valve rod, spheroid and the driving mechanism be connected with valve rod, wherein, the top of valve body is provided with groove, the through hole connecting this groove and spheroid chamber is provided with in valve body, the seal gasket mated with groove size is provided with in the groove of valve body, valve rod one end through seal gasket and valve body through hole and be connected with spheroid, interference fit is formed between seal gasket and valve rod, the present invention adopts said structure, overall structure is simple, be convenient to realize, and the present invention comes the gap between sealed valve body and valve rod by the seal gasket be embedded in groove, seal gasket forms the sealing configuration in gap between valve body and valve rod, because seal gasket is direct and extraneous contact, it is easy to operate when it is changed, avoiding problems and cause ball valve not re-use the caused wasting of resources because of the seal structure damage between valve body and valve rod, the present invention is prior art more saving resource comparatively.
