Abstract
The utility model discloses a kind of fluid pipe deceleration valve gate housing, comprising: valve cavity, the transmission shaft running through described valve cavity top and rotating shaft platform, be provided with some oblique stiffening ribs between described rotating shaft platform and valve cavity.Described valve cavity inwall is provided with movable chamber, and described movable chamber central authorities arrange Turbogrid plates column.The Turbogrid plates of described Turbogrid plates column both sides can be set to different sizes, namely can adjust with the area of fluid-flow contact.There is certain space between described movable chamber and valve cavity, the surplus between movable chamber and valve cavity arranges and ensure that when liquid flow impact, can have the space of buffering, can not directly be delivered on valve body by impulse force, extend the working life of valve entirety.
Description
Technical field
The utility model relates to a kind of deceleration valve, more particularly, relates to a kind of for fluid pipe deceleration snubber valve gate housing.
Background technique
Butterfly valve is Flap valve again, is the simple modulating valve of a kind of structure.Refer to that closure member (flap or butterfly plate) is disk for the valve butterfly valve in the mode work of the switch control rule of low pressure pipeline medium, rotate a kind of valve reaching open and close around valve shaft, on pipeline, main rising is cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.As can be seen here, turnover panel is the significant components of butterfly valve, and turnover panel is determined the impact that can suffer liquid stream for a long time by its working principle, although be the liquid stream be in low pressure pipeline, still can suffer than stronger liquid flow impact in the moment opened and closed.The butterfly valve of general use turnover panel is exactly blocked by the liquid stream in pipeline when cutting out, no longer include liquid to flow through, but liquid stream just will turn down by the object in some situations, or impact force reduces before liquid flows to destinations such as reaching reaction tank, under such circumstances or select frequent opening/shutting valve, or just can only turn down liquid emitting rate in the source of liquid flow tube.
How in pipeline, using simple method, the surge pressure reducing rapidly liquid stream is the problem that industry technician needs to consider.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, claimant, through repeatedly putting into practice improvement, devises a kind of fluid pipe deceleration valve gate housing, and when mainly solving that flow stream velocity is too fast in pipeline, common valve cannot conveniently slow down the problem remained in a standstill.
Technological scheme: in order to realize foregoing invention object, the technological scheme that the utility model adopts is: a kind of fluid pipe deceleration valve gate housing, its structure comprises: valve cavity, the transmission shaft running through described valve cavity top and rotating shaft platform, be provided with some oblique stiffening ribs between described rotating shaft platform and valve cavity.
Described valve cavity inwall is provided with movable chamber, and described movable chamber central authorities arrange Turbogrid plates column.The Turbogrid plates of described Turbogrid plates column both sides can be set to different sizes, namely can adjust with the area of fluid-flow contact, so just can play the effect of slowing down and remaining in a standstill when liquid flows through.
There is the space of 1-2mm between described movable chamber and valve cavity, the surplus between movable chamber and valve cavity arranges and ensure that when liquid flow impact, can have the space of buffering, can not be directly delivered on valve body by impulse force.
Further, described movable cavity wall is provided with caulking gum packing ring.
Again further, described rotating shaft platform is provided with the through hole run through for transmission shaft, and it is special-shaped driveshaft that described transmission shaft protrudes rotating shaft platform section.Described special-shaped driveshaft is used for muff-coupling wrench or valve plate.
Further, described transmission shaft is provided with instruction gear, and described instruction gear is arranged on rotating shaft platform lower end.
Described instruction geared sleeve is connected on transmission shaft.Described instruction gear is a flange one side of something being processed as profile of tooth.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
The space of 1-2mm is there is between movable chamber and valve cavity described in this practicality, surplus between movable chamber and valve cavity arranges and ensure that when liquid flow impact, the space of buffering can be had, can not directly impulse force is delivered on valve body, extend the working life of valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fluid pipe deceleration valve of the utility model gate housing.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of fluid pipe deceleration valve gate housing, its structure comprises: valve cavity 1, the transmission shaft 3 running through described valve cavity 1 top and rotating shaft platform 4, be provided with some oblique stiffening ribs 2 between described rotating shaft platform 4 and valve cavity 1.Described valve cavity 1 inwall is provided with movable chamber 6, and described movable chamber 6 central authorities arrange Turbogrid plates column 7.
Described movable chamber 6 inwall is provided with caulking gum packing ring 5.
Described rotating shaft platform 4 is provided with the through hole run through for transmission shaft 3, and it is special-shaped driveshaft 8 that described transmission shaft 3 protrudes 4 sections, rotating shaft platform.
Described transmission shaft 3 is provided with instruction gear 9, and described instruction gear 9 is arranged on rotating shaft platform 4 lower end.
Described instruction gear 9 is socketed on transmission shaft 3.
Described instruction gear 9 is a flange one side of something being processed as profile of tooth.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
