Ball valve 5 generally comprises left diaphragm seal 51, valve ball 52, right diaphragm seal 53, valve seat 54, valve rod 55, handle 56.Valve port with the attachment structure of ball valve is: set gradually left diaphragm seal, valve ball, right diaphragm seal, the left part of valve seat in the valve pocket within valve port 12, the left part 541 of valve seat is stretched into valve pocket and is threaded connection with valve pocket, the end face of valve port right-hand member and the valve seat right-hand member diameter contact being positioned at outside valve pocket, be pressed in valve pocket by the left diaphragm seal in 541, left part, valve ball, right diaphragm seal.Left diaphragm seal, valve ball, right diaphragm seal, valve pocket, the parts such as left part of valve seat are required the highest at size, the quality of fit of valve pocket axial direction by this structure, very big improve processing and assembly cost；If the size having parts goes wrong, arise that leakage problem, especially there will be and between valve ball and left diaphragm seal, right diaphragm seal, seal the unreliable leakage problem caused.
This tee ball valve, valve seat also quickly cannot be connected with the external hose (such as the flexible pipe of water purifier) of other watering equipments.In order to be quickly connected with external hose, need to install again the snap joint of an extra purchase on valve seat.Snap joint belongs to prior art, but price is higher.Valve seat can be connected with external hose by snap joint.
Summary of the invention
The purpose of this technology be to provide a kind of with simple in construction, simple installation, with low cost, seal and connect tee ball valve soon reliably.
Connecing tee ball valve soon described in this technology, have valve body, valve body has three ports communicated, and one of them port is the cap port of connection activity nut, and a port is the valve port of mounting ball valve；Cap port with the concrete attachment structure of movable nut is: have the draw-in groove that width is s in the cap port periphery of a diameter of a, jump ring embeds draw-in groove；The front end face of cap port is t to the distance of draw-in groove；Jump ring is f at the width of radial direction, and the thickness at axial direction is x；Embedding the jump ring external diameter after draw-in groove is b；Movable nut includes endoporus and the reducing at rear portion of front portion, and diameter of bore is c, and reentrant diameter is e；Step surface is formed between reducing and endoporus；Have a diameter of d on inner hole wall, width is the seal groove of y, and the distance of step surface to seal groove is z；A≤e ＜ b≤c ＜ d, a+2f≤d, x≤s, z≤s+t；Under external force, form, with the front end face of cap port, the sealing ring being in sealing contact be positioned at seal groove；Movable screw cap sleeve is contained in cap port periphery, is more than reentrant diameter e owing to embedding the jump ring external diameter b in draw-in groove, prevents movable nut to move forward thus departs from cap port；On endoporus between movable nut front end and seal groove, there is female thread；With round-corner transition between step surface and inner hole wall；Inside at least one port in two other port in addition to cap port, being axially provided with O RunddichtringO and resilient sleeve, resilient sleeve has the arc spring lamination being looped around circumferential more than three and the closed-loop being jointly connected with same one end of each arc spring lamination；Each arc spring lamination all has the claw being positioned on same circumference.
The beneficial effect of this technology: this technology has abandoned spacing to movable nut of the conventional pressure cap being threaded connection, but by a jump ring in cap port periphery realize movable nut spacing, simple in construction, reduce cost, it also avoid and use the tightening tool convection cell passage when pressure cap is tightened stretching into pressure cap endoporus to pollute, also eliminate the screw thread pair between pressure cap with cap port simultaneously and be connected the risk of leakage of easily appearance.Step surface to the distance z in the axial direction≤draw-in groove of seal groove trailing flank in the front end face of the width s+ cap port of axial direction to distance t of draw-in groove front side wall, make when jump ring contacts with step surface, seal groove trailing flank is in the rear portion of the front end face of cap port or the position concordant with the front end face of cap port, so, when exterior line with this connect soon tee ball valve be connected time, exterior line by with screw-internal thread fit on movable nut, the end face of exterior line can be pressed on sealing ring in the front end face of cap port, it is achieved reliably seals.When in sealing ring embedding sealing ring recess, sealing ring also limit the movable nut displacement in axially direction, and compact conformation is easy to use.
Round-corner transition reduces the stress of junction between step surface and inner hole wall and concentrates, and bearing capacity is big, prevents fracture.
O RunddichtringO and resilient sleeve are the parts in snap joint, in other ports in addition to cap port that this technology is applied to two main parts in snap joint on this valve body, serve the purpose being quickly connected with external hose.So, it is not necessary to the snap joint that purchasing price is expensive again, it is possible to realize quickly being connected with external hose.During use, external hose stretches in O RunddichtringO and resilient sleeve, and external hose is in sealing contact with the O RunddichtringO of periphery, and the most each claw, under the elastic reaction of each arc spring lamination, is connecing flexible pipe clamping and positioning radially outward.
Above-mentioned meets tee ball valve, c ＜ a+2f soon；x≤y.As such, it is possible to the size of further reduction activity nut, reduce cost.
Above-mentioned connects tee ball valve soon, and on cap port periphery, the rear portion of draw-in groove arranges the limiting stand that restraint nut continues to move to backward, and when not installing sealing ring, movable nut can move axially between jump ring and limiting stand；When movable nut contact with limiting stand can not be moved rearwards by time, the trailing flank of seal groove and the trailing flank flush of draw-in groove or be positioned at the rear of trailing flank of draw-in groove.By arranging limiting stand, limit the movable nut moving range at axial direction so that it is compacter that this connects tee ball valve structure soon, reduces cost.When installing jump ring, in order to make jump ring load smoothly in draw-in groove, the trailing flank preventing seal groove may stop that jump ring is moved rearwards by, jump ring can not be entered in draw-in groove, so should require when movable nut contact with limiting stand can not be moved rearwards by time, the trailing flank of seal groove and the trailing flank flush of draw-in groove or be positioned at the rear of trailing flank of draw-in groove.As improving further, best c ＜ a+2f；x≤y；So, profile is smaller and more exquisite, with low cost；But now bring difficulty for not installation to jump ring, best right angle setting during set assembling jump ring, first jump ring is sleeved on the periphery at cap port front end face, and make jump ring be positioned at seal groove, again by promoting jump ring to be moved rearwards by from the instrument stretched between endoporus and cap port, movable nut can follow movement, makes jump ring slip into smoothly in draw-in groove；And such tee ball valve that connects soon has an advantage that, it is simply that after jump ring is installed in draw-in groove, it is impossible to take off in draw-in groove again, that is, jump ring cannot depart from cap port periphery, and the most movable nut the most just cannot take off (departing from cap port periphery), safety when adding use, transport.
Above-mentioned meets tee ball valve, a ＜ e ＜ b ＜ c ＜ a+2f ＜ d, x≤y, x=s, z=s+t soon；Thickness≤the y of sealing ring.So, while compact structure, movable nut moves axially or is rotated about axis the most flexible relative to cap port.
Above-mentioned connects tee ball valve soon, and the cross section of jump ring is circular, and the cross section of draw-in groove is arc.Arc-shaped slot cross section can reduce cap port periphery stress at draw-in groove and concentrate, and prevents fracture.
