The technological scheme of the utility model is: a kind of Y type multi-functional valve comprises valve body, flap and valve rod; Valve body is provided with valve seat, and flap can seal with valve seat mutually, and valve rod can straight reciprocating motion; Flap is provided with link; Socket-connect between described link and the valve rod, can be free to slide relatively between valve rod and the link, the stroke of valve rod is enough to make valve rod and flap to offset and makes between flap and the valve seat and compresses.
Described valve body is provided with valve-rod cavity, the described valve-rod cavity valve gap that is tightly connected, and valve rod passes valve gap and is threaded with it, is provided with the filler that seals mutually with valve rod and compressed by the filler gland in the valve gap.
Described link is rod member or pipe fitting and the center that is positioned at flap, corresponding circular hole or the cylinder that matches with link that be provided with on the valve rod.
Described flap is provided with damping hole, and damping hole makes the inlet passage of valve body communicate with outlet passage.
The inlet passage of described valve body and outlet passage are positioned at same straight line, and valve-rod cavity on the valve body and outlet passage form certain included angle and be " Y " type structure.
The utlity model has following beneficial effect: owing to take such scheme; The utility model integrates the function of stop valve, safety check and modulating valve; No clamping stagnation, no trapping phenomena; Favorable sealing property, long service life, have simple in structure, volume is little, low cost of manufacture and characteristics convenient for installation and maintenance.
Description of drawings
Accompanying drawing 1 is the structure sectional view of the utility model.
1-valve body among the figure, 2-flap, 3-valve rod, 4-valve seat, 5-link, 6-valve-rod cavity, 7-valve gap, 8-filler gland, 9-filler, 10-damping hole, 11-inlet passage, 12-outlet passage, 13-handwheel.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1, a kind of Y type multi-functional valve comprises valve body 1, flap 2 and valve rod 3, and valve body 1 is provided with valve seat 4; Flap 2 can seal with valve seat 4 mutually; Valve rod 3 can straight reciprocating motion, and flap 2 is provided with link 5, socket-connects between described link 5 and the valve rod 3; Can be free to slide relatively between valve rod 3 and the link 5, the stroke of valve rod 3 is enough to make valve rod 3 and flap 2 to offset and makes between flap 2 and the valve seat 4 and compresses.The external part of valve rod 3 connects handwheel 13, owing to take such scheme, the utility model to be divided into following three kinds of situation in use:
1. when being used as stop valve and using, purpose is to block medium channel, then rotation hand wheel 13 and drive valve rod 3 rotations; Valve rod 3 offsets to flap 2 motions and with it; Through valve rod 3 lower end surfaces compressing flap 2, continue rotation hand wheel, till flap 2 and valve seat 4 compress sealing; If the connection medium channel, then the counterrotating handwheel 13, and valve rod 3 is raised, and valve rod 3 separates with flap 2, at this moment flap 2 under the flowing medium Driving force, lift off a seat 4 and free skating to valve rod 3, medium channel is communicated with.
2. when being used as safety check and using: rotation hand wheel 13 drives valve rods 3 and rotates, and makes valve rod 3 be positioned at the top of valve body 1, and flap 2 promotes flap 2 along valve rod 3 upwards slippages under pressure medium, make medium channel be communicated with; If flowing medium refluxes, then place, medium inlet instantaneous loss of pressure forms local negative pressure, and flap 2 is under the double-action of the pressure of self gravitation and the formation of flowing medium reverse flow, and compressing flap 2 moves down, till flap 2 is pressed on the valve seat 4.During as safety check, this valve also capable of using has the characteristic of stop valve, presses under the operating mode at system's band and forces non-return.
3. when being used as the modulating valve use: utilize multi-functional valve to can be used as the characteristic of stop valve,,, can realize regulation and control to flow as long as guarantee not tight closure of flap 2 and valve seat 4 through adjusting handle 13.
In sum, the utility model integrates the function of stop valve, safety check and modulating valve, no clamping stagnation, no trapping phenomena, favorable sealing property, long service life, have simple in structure, volume is little, low cost of manufacture and characteristics convenient for installation and maintenance.
By shown in Figure 1, described valve body 1 is provided with valve-rod cavity 6, described valve-rod cavity 6 valve gap 7 that is tightly connected, and valve rod 3 passes valve gap 7 and is threaded with it, is provided with the filler 9 that seals mutually with valve rod 3 and compressed by filler gland 8 in the valve gap 7.The part that valve rod 3 stretches out valve gap 7 links to each other with handwheel 13, rotates handwheel 13, valve rod 3 is rotated, while valve rod 3 rotates straight line motion.Make the mechanism of valve rod 3 straight reciprocating motions that various ways arranged, present embodiment only as preferably, is not enumerated for other common prior art constructions one by one.Filler 9 makes sealing between valve rod 3 and the valve gap 7, and valve gap 7 is threaded with valve-rod cavity 6 or flange is connected, when leaking appears in valve; The dismounting valve gap can take out flap 2; Change seal ring, overcome the defective that seal ring was safeguarded and was difficult for changing in similar safety check inconvenience, easy to maintenance.
By shown in Figure 1, described link 5 is for rod member or pipe fitting and be positioned at the center of flap 2, corresponding circular hole or the cylinder that matches with link 5 that be provided with on the valve rod 3.The link 5 that is provided with on the preferred flap 2 of present embodiment is a pipe fitting, and the end of valve rod 3 is the entity cylinder.Can certainly circular hole be set at valve rod 3, the link 5 on the flap 2 is a cylindrical body.
By shown in Figure 1, described flap 2 is provided with damping hole 10, and damping hole 10 makes the inlet passage 11 of valve body 1 communicate with outlet passage 12.Damping hole 10 produces damping function when flap 2 opening and closing, effectively reduces vibration and the generation that reduces water hammer.
By shown in Figure 1, the inlet passage 11 and the outlet passage 12 of described valve body 1 are positioned at same straight line, and the valve-rod cavity 6 on the valve body 1 forms certain included angle with outlet passage 12 and is " Y " type structure.Valve body 1 adopts the y-type structure of one-step casting moulding, has reduced the installing space and operation height of valve.
