Description
Technical field
The utility model relates to a kind of manual platform gate valve.
Background technique
The recovery process of oil gas needs the discrepancy being controlled downhole fluid by the switch of valve; when occurring emergency case; need rapid-closure damper to protect pipeline safety; existing manual flat valve is by structural limitations; throttle down needs more than 30 seconds, the structure that this opening/closing time is longer, can not ensure the safety of pipeline; therefore be necessary to design a structure more reliable, valve that can be rapidly opened and closed.
Summary of the invention
In order to overcome the defect of prior art, the utility model provides following technological scheme:
A kind of manual platform gate valve, it comprises lower valve bonnet, guide rod, valve body and valve plate, lower valve bonnet covers at guide rod outside, valve body is connected by mesopore steel ring with lower valve bonnet, valve body is installed on valve seat, the first shape of the mouth as one speaks circle is provided with between described valve seat and valve plate, guide plate and valve gap is provided with above valve seat, valve gap right-hand member is provided with grease pouring valve, the lip filler matched with grease pouring valve is provided with above valve gap left end, upper Packing seat and lower Packing seat, Gland is provided with above described upper Packing seat, described Gland is connected with support by the second shape of the mouth as one speaks circle, the right side of support is provided with lubricating cup, support passes on left the 3rd shape of the mouth as one speaks circle, two bearings and bearing gland are connected with Stem Mut, valve rod is provided with on the left of Stem Mut, valve rod upper end is through handwheel, described handwheel overcentre is provided with the upper valve bonnet and transparent cover that match with valve rod.
Further, be also provided with wavy spring between described valve plate and valve seat, described valve gap is connected with valve seat with a year silk bolt by hexagon nut, and described Gland is connected with valve gap by Cock screw, is provided with enlightenment board below valve rod.
The beneficial effect that the utility model brings is: compare existing valve, and its opening and closing speed improves greatly, has effectively ensured the safety of pipeline.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
