Abstract
The utility model provides a twin -lock stop valve, includes the valve body, the valve clack, and the valve gap, the valve rod, valve body both ends and pipe connection, centre have a cylindrical cavity, and the cylindrical cavity of valve body is placed in to the valve clack, there is a rectangle recess valve clack upper end, the rectangle recess with valve rod one end is connected, wherein the valve rod penetrates through the valve cover, the valve gap passes through the screw to be connected with the valve body, its characterized in that, the valve clack includes circular valve clack of level and vertical rectangular valve clack, circular valve clack of level and valve body water inlet phase -match, vertical rectangular valve clack and valve body delivery port phase -match. Compare with traditional stop valve, through addding the vertical rectangular valve clack in the circular valve clack one end of level, when closing this valve, respectively to intake the end with go out the water end (W. E. ) and carry on two -way ending, even in higher water pressure or the sealed occasion that expects much, also can carry on effectual by and can not produce microleakage.
Description
Technical field
This utility model relates to valve technology field, is specifically related to a kind of stop valve.
Background technology
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve, so when valve closing, it is necessary to apply pressure to flap, do not leak with forced seal face.When medium is by when entering valve below flap, the resistance overcome required for operating physical force, be valve rod and filler frictional force with by thrust produced by the pressure of medium, the power of the force rate valve opening door of closing valve is big, so the diameter of valve rod wants big, the fault of valve rod bending otherwise can occur.In the pipeline that stop valve is typically installed, fluid flow is big, produced pressure is the biggest, bigger pressure causes being susceptible to micro-leakage at sealing, or corrosive liquids also can produce corrosiveness to the packing ring at sealing and cause micro-leakage, in the occasion that sealing requirements is higher, this common stop valve can not meet requirement.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that a kind of novel twin-lock stop valve.
Technical problem to be solved in the utility model uses following technical scheme to realize:
A kind of twin-lock stop valve, including valve body, flap, valve gap, valve rod, described valve body two ends are connected with pipeline, and centre has circular cylindrical cavity, described flap to be placed in valve cylinder-shaped cavity, described flap includes level circle flap and vertical rectangle flap, level circle flap matches with valve inleting water mouth, and lower end is fixing is stained with sealing gasket, and vertical rectangle flap matches with valve body outlet, there is rectangular recess described flap upper end, rectangular recess is connected with described valve rod one end, and described valve rod passes valve gap, and described valve gap is connected with valve body by screw.
The described valve rod other end connects handwheel, and this valve rod is positioned at valve gap lower end and arranges centring ring, prevents from rotating when rotating handwheel excessively causing valve rod to come off with flap.
Described valve gap arranges porose with described vertical rectangle flap corresponding position, and upper end, hole correspondence vertical rectangle flap is provided with rectangular flap set, and when opening this stop valve, vertical rectangle flap rises in rectangular flap set along this hole.
Described rectangular flap set it is preferably provided as transparent material, and so in overlapping through this flap, whether vertical flap stretches out valve gap it may determine that go out this stop valve and be in closed mode and be in opening.
The beneficial effects of the utility model are: compared with tradition stop valve, by setting up vertical rectangle flap in level circle flap one end, when closing this valve, respectively water inlet end and water side are carried out two-way stop, even if in the occasion that higher hydraulic pressure or seal request are high, also can effectively end without producing micro-leakage.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As shown in Figure 1, a kind of twin-lock stop valve, including valve body 1, flap 2, valve gap 4, valve rod 3, valve body 1 two ends are connected with pipeline, there is circular cylindrical cavity 9 centre, flap 2 is placed in valve body 1 circular cylindrical cavity 9, and flap 2 includes that level circle flap 5 and vertical rectangle flap 6, level circle flap 5 match with valve body 1 water inlet, lower end is fixing is stained with sealing gasket 8, vertical rectangle flap 6 matches with valve body 1 outlet, and flap 2 upper end has rectangular recess, rectangular recess to be connected with valve rod 3 one end, valve rod 3 is connected with valve body 1 through valve gap 4, valve gap 4 by screw 11.
Valve rod 3 other end connects handwheel 10, and valve rod 3 is positioned at valve gap lower end and arranges centring ring 12, prevents from rotating when rotating handwheel 10 excessively causing valve rod 3 to come off with flap 2.
Valve gap 4 arranges porose with vertical rectangle flap 6 corresponding position, and upper end, hole correspondence vertical rectangle flap 6 is provided with rectangular flap set 7, and when opening this stop valve, vertical rectangle flap 6 rises in rectangular flap set 7 along this hole.
Rectangular flap set 7 it is preferably provided as transparent material, and so whether vertical flap stretches out valve gap 4 it may determine that go out this stop valve and be in closed mode and be in opening in through this flap set 7.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
