Background technique
The opening and closing element of manual gate valve is flashboard, and the direction of motion and flow direction of flashboard are perpendicular, and gate valve can only make standard-sized sheet
It is closed with complete, cannot make adjustments and throttle.There are two sealing surface, two sealing surfaces of most common mode slide valve to form wedge for flashboard
Shape, key groove are different with valve parameter, and usually 50, it is 2 ° of 52' when medium temperature is not high.The flashboard of Wedge Gate Valves can be made
One entirety, is called rigid flashboard；Also it can be made the flashboard that can generate micro-deformation, to improve its craftsmanship, make up sealing
The deviation that face angle degree generates in process, this flashboard are called flexible disc.Manual gate valve, national standard gate valve, cast steel gate valve
Type, by sealing surface configuration can be divided into wedge gate type gate valve and parallel gate type gate valve, wedge gate type gate valve can divide again
For:Gate type, double ram type and flexible gate type；Parallel gate type gate valve can be divided into single disc formula and double ram type.By valve
The screw position of bar divides, and can be divided into Outside screw stem rising through handwheel type gate valve and two kinds of inside screw nonrising stem type gate valve.
Present gate valve repairs very difficult, and valve switching times are longer, and use when is laborious, and runs
Get up unstable.
Utility model content
Purpose of the utility model is to solve disadvantages mentioned above, and a kind of manual wedge-type Outside screw stem rising through handwheel type gate valve proposed.
To achieve the goals above, the utility model uses following technical solution：
A kind of manual wedge-type Outside screw stem rising through handwheel type gate valve is designed, including the second valve body that horizontal positioned and left and right communicates, second valve
It is equipped with the first valve body above body, has been bolted valve deck by first above first valve body, by the above the valve deck
Two bolts are connected with bracket, and the pedestal upper end inner rotation is connected with valve stem nut, set in the valve stem nut bottom cylindrical week
There is annular flange, and annular flange upper and lower is equipped with thrust ball bearing, the valve stem nut upper end is connected with handwheel, described
Flat key is equipped between handwheel and valve stem nut, the valve stem nut internal whorl is connected with valve rod, and the valve rod bottom end is connected with
The flashboard being used cooperatively with the second valve body.
By rotating handwheel, valve stem nut rotation is driven, thus band ovable valve stem moves up and down, and controls ram movement, realizes
Valve opening and closing, it is more laborsaving due to behaving by the way of threading action, it is pushed away due to being equipped between valve stem nut and bracket
Power ball bearing increases the stability of operation, since valve body is formed using multiple component combinations, greatly facilitates installation and maintenance.
Preferably, gasket is equipped between the valve deck and the first valve body.
Preferably, the bracket and valve deck junction are equipped with gland, and the gland is set in stem exterior, institute
It states gland to be fixed on valve deck by pivot pin, the gland bottom is placed with filler, and the filler is placed on valve deck
In the filler placing groove opened up, prevent from revealing.
Preferably, the flashboard passes through third bolt fastening together by two and half flashboards, stem bottom section shape
Shape is I-shaped, and is fastened between two and half flashboards, and disassembly is easily installed.
The utility model proposes a kind of manual wedge-type Outside screw stem rising through handwheel type gate valve, beneficial effect is：The utility model uses
It is simple and convenient, behave it is reliable and stable, installing and dismounting maintenance it is more convenient.
