Abstract
The utility model provides a self-lifting big flow valve new structure which is suitable for opening and closing a pipeline. A valve rod is movably connected with a valve cover; when the valve rod is spiraled up and down, the valve cover rises and falls consequently to play the functions of opening and closing the valve; the valve cover is wear-resistant. The utility model provides a big flow capacity, small damping, simplicity and reliability; the point of the valve rod is sealed, due to the use of a self-sealing nut.
Description
The utility model provides a kind of hand-held large-capacity valve door new structure, and existing this structure is used is the example explanation on running water valve.
Running water valve commonly used now, valve rod and valve gap do not connect, and when the valve rod spiral promoted, valve gap relied on hydraulic pressure jack-up and opens valve, and when hydraulic pressure was low, the valve water outlet was just less, not even water outlet; When hydraulic pressure was higher, valve gap was by jack-up, was subjected to water impact again simultaneously and up and down, caused that the water route is not smooth, and water outlet is just very anxious, causes that spray splashes.Existing valve also exists valve rod place seepage phenomenon, makes water flow to the vessel outside, has wasted water resources.Also have a kind of valve, the valve gap rubber tissue directly is contained on the valve rod, and at valve opening with when closing, rubber tissue reverses friction on valve port, very easily wearing and tearing, and be difficult for using outside Constant Low Temperature Facilities, in case valve freezes, rubber tissue will damage or pull.
The utility model provides a kind of hand-held valve new structure, and water-outlet quantity is big and current slow, has shortened the water intaking time, and has used self-styled nut new structure, has stopped valve rod place seepage phenomenon, has saved water resources.
The utility model is realized with following structure, sees Fig. 1, Fig. 2, and valve is by valve body (1), valve port (2), bonnet nut (3), valve cap plate (4), valve gap body (5), jump ring (6), valve rod (7), valve rod base (8), self-styled nut (9), valve handle (10) is formed.
There is a blind hole valve rod (7) lower end, and 1～3 millimeter away from blind hole mouth place opens two parallel grooves perpendicular to the blind hole center line be, and saturating groove incision blind hole 0.5～1 millimeters deep is convenient to jump ring (6) and is inserted.Valve gap (11) is by valve cap plate (4), bonnet nut (3), valve gap body (5) assembles, (also can be made into one in addition part replace, see Fig. 3 part (11) in addition).On valve gap (11) convex, cut a groove (see figure 2), when the valve gap convex inserts valve rod (7) blind hole, insert and snap in valve gap convex groove from the saturating grooves of (7) two of valve rods with jump ring (6), then valve rod (7) and valve gap (11) just activity connected.
Valve rod (7) cooperates with trapezoidal thread with valve rod base (8).When direction of valve rod (7) screw promoted, valve gap (11) was followed lifting under jump ring (6) effect, and valve gap (11) leaves valve port (2) (promptly open valve, make liquid or gas communication).Valve gap (11) axially is being subjected to valve rod (7) control aspect the lifting along valve rod (7), but around aspect valve rod (7) axial rotation degrees of freedom being arranged, (under external force promptly, valve gap (11) can be done suitable, counterclockwise 360 ° of rotations around valve rod (7) axis).
When valve rod (7) spiral descended, valve gap (11) was followed decline.When driving valve gap (11), valve rod (7) drops to when pushing down valve port (2), the friction that valve gap (11) and valve port (2) produce can not be rotated valve gap, the surface of contact of valve rod (7) and valve gap (11) is around valve rod (7) axis sliding friction, (be that valve rod (7) rotates, valve gap (11) does not rotate) is till throttle down.
The activity of valve rod in the utility model (7) and valve gap (11) connects and comprises alternate manner, and wherein useful screw attachment is seen Fig. 3.Key is that the activity that will reach valve rod (7) and valve gap (11) connects, purpose has promoted valve gap (11) when being the lifting of valve rod (7) spiral, opened valve, do not need the water valve gap that bears down on one out, simultaneously, the activity of valve rod (7) and valve gap (11) connects in the time of can reducing the frequent switch of valve, and the wearing and tearing of valve cap plate (4) are to guarantee that valve uses reliably and with long-term.
Self-styled nut (9) and valve rod base (8) scyewed joint are seen Fig. 1, Fig. 4, the center hole of self-styled nut (9) and valve rod (7) transition fit.When self-styled nut (9) revolves when dropping to end-cone face and the corresponding conical surface of valve rod base (8) and being close to sealing, self-styled nut (9) end-cone body stress deformation shrinks, valve rod (7) is encased sealing, so, valve rod (7) can be under external force, overcome with the friction of self-styled nut (9) and rotate ascending, descending, but liquid or gas can not seepages.
When the utility model is implemented, do not increase manufacture cost, do not change the valve latus rectum, can be directly installed on the pipe joint place of former valve.Under equal conditions relatively use, water-outlet quantity is 1.5～2 times of former valve.The area high to hydraulic pressure, water-outlet quantity is big and current slow, and waterproof flower splashes, and is non-leakage; The water intaking time can be shortened greatly in the area low to hydraulic pressure.
Claims (2)
1, one by valve body (1), valve port (2), and valve gap (11), jump ring (6), valve rod (7), valve rod base (8), self-styled nut (9), valve handle (10) have been formed hand-held large-capacity valve door new structure.
Valve rod (7) and valve gap (11) connect by jump ring (6) is movable, and following feature is arranged after the connection:
A: when lifting of valve rod (7) spiral or decline, valve gap (11) is followed and is promoted or decline.
B: when valve gap (11) was not pushed down valve port (2), valve gap (11) axially was subjected to valve rod (7) control in the lifting aspect along valve rod (7), but valve gap (11) is around aspect valve rod (7) rotational degrees of freedom being arranged.(under external force promptly, valve gap (11) can be done suitable, 360 ° of rotations counterclockwise around valve rod (7) axis).
C: drop to when pushing down valve port (2) when valve rod (7) drives valve gap (11), the friction that valve gap (11) and valve port (2) produce can not be rotated valve gap (11), the surface of contact sliding friction of valve rod (7) and valve gap (11), (be that valve gap (11) does not rotate, valve rod (7) rotates), till throttle down.
2,, it is characterized in that self-styled nut (9) and valve rod base (8) use scyewed joint, self-styled nut (9) center hole and valve rod (7) transition fit according to the described hand-held large-capacity valve of claim 1 door new structure.Drop to end-cone face and valve rod base (8) conical surface and be close to when contacting when self-styled nut (9) revolves, following feature is arranged:
A: the contact conical surface sealing of self-styled nut (9) end-cone face and valve rod base (8), self-styled nut (9) cone distortion is simultaneously shunk, and the center hole after the contraction encases sealing with valve rod (7).
B: valve rod (7) can overcome and contacts the friction that produces with self-styled nut (9) and spiral lifting under external force.
C: self-styled nut (9) had both played and valve rod (7) and valve rod base (8) seal action, simultaneously, again valve rod (7) was played the role of positioning.
