Description
Technical field
The present invention relates to valving, a kind of specifically multi-functional valve.
Background technique
The valve of using if classify according to the effect and the function of its door, can be divided into five big classes such as blocking class, non-return class, adjusting class and shunting class, security classes at present.Traditional classification has its certain science, as blocks the class valve, and the main effect of its door is the medium that is used for connecting or block in the pipeline; Non-return class valve then is mainly used in and prevents that medium from flowing backwards; Adjusting class valve then can play flow and the pressure regulating action within the specific limits to the medium that flows in the pipeline.
The effect difference of above-mentioned all kinds of valves, its structure characteristic also is not quite similar, because the application of valve is very extensive, the structure characteristic of all kinds of valves has here just repeated no more.
Generally speaking, on the medium transport pipeline because of the requirement difference of technological process, sometimes need to block medium, need again to prevent that medium from flowing backwards sometimes, sometimes require again the flow and the pressure of medium are regulated, this just need be provided with stop valve, gate valve, safety check and modulating valve respectively on pipeline, to occupy certain length of pipeline and space on the one hand like this, waste great deal of steel, the energy on the other hand again, increase installation and maintenance expense and possible accident origination point.
Summary of the invention
The object of the present invention is to provide a kind of multi-functional valve, can when technological process needs, play the effect of gate valve, stop valve, safety check and modulating valve respectively, simple in structure and low cost of manufacture.
For reaching above purpose, the technological scheme that the present invention takes is:
A kind of multi-functional valve, comprise valve body 14, valve body 14 tops are provided with valve gap 4, the through hole that valve rod 3 passes on the valve gap 4 is connected with valve body 14 interior pistons 7, piston 7 is provided with seal ring 6, the joint of piston 7 and valve rod 3 is provided with divided ring 5, valve rod 3 tops are provided with the handwheel of fixing by nut 12, be provided with valve seat 13 in the valve body 14, it is characterized in that: be provided with bearing pin 8 in the valve body 14, be connected with bearing pin 8 by support 9 with valve seat 13 adaptive flaps 12, support 9 is provided with the pin 10 adaptive with piston 7, and pin 10 is provided with roller 11.
On the basis of technique scheme, bearing pin 8 and valve seat 13 are positioned at the same side of valve body 14.
The present invention has the following advantages:
1. can when needing, technological process play the effect of gate valve, stop valve, safety check and modulating valve respectively,
2. simple in structure,
3. low cost of manufacture.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is the structural representation of multi-functional valve, as shown in Figure 1, the said multi-functional valve of the present invention comprises valve body 14, valve body 14 tops are provided with valve gap 4, the through hole that valve rod 3 passes on the valve gap 4 is connected with valve body 14 interior pistons 7, piston 7 is provided with seal ring 6, the joint of piston 7 and valve rod 3 is provided with divided ring 5, valve rod 3 tops are provided with the handwheel of fixing by nut 12, be provided with valve seat 13 in the valve body 14, be provided with bearing pin 8 in the valve body 14, be connected with bearing pin 8 by support 9 with valve seat 13 adaptive flaps 12, support 9 is provided with the pin 10 adaptive with piston 7, and pin 10 is provided with roller 11.Valve seat 13 is arranged on the place, medium inlet of valve body 14 bottoms.Support 9 and bearing pin 8 are for flexibly connecting, and support 9 can rotate around bearing pin 8 in valve body 14, and support 9 and being connected of bearing pin 8 can be adopted existing techniques in realizing.Said nut 1, handwheel 2, valve rod 3, valve gap 4, divided ring 5, seal ring 6, piston 7, bearing pin 8, support 9, pin 10, roller 11, flap 12, valve seat 13 and valve body 14 all can adopt existing techniques in realizing, valve seat 13 is equivalent to sealing and pays, flap 12 is equivalent to kinematic pair, can reach liquid sealing after valve seat 13 and flap 12 closures.On the basis of technique scheme, bearing pin 8 and valve seat 13 are positioned at the same side of valve body 14, and the position of bearing pin 8 is higher than the position of valve seat 13, and under the situation that the space allows in valve body 14, bearing pin 8 also can be positioned at the middle part of valve body 14.As shown in Figure 1, for support 9 and bearing pin 8 are set, the corresponding site of valve body 14 is provided with the depressed part adaptive with support 9, and the setting of support 9 and bearing pin 8 also can be adopted existing techniques in realizing.The working principle of multi-functional valve of the present invention is as follows:
1, realizes the effect of stop valve: if block medium channel, rotation hand wheel and drive valve rod and rotate then, promote piston and do downward straight line motion, lower end surface compressing roller 11 by piston, the support 9 that is connected with roller 11 is turned clockwise, till driving flap 12 and being pressed onto above the valve seat and reaching required seal pressure along bearing pin 8; If connection medium channel, counterrotating handwheel and drive the valve rod backward rotation then, lift piston and do straight line motion upwards, make the lower end surface of piston separate with roller, at this moment flap 12 is under the Driving force of flowing medium, drive support 9 and be rotated counterclockwise, make medium channel connect along bearing pin 8.
2, realize the effect of safety check: rotation hand wheel also drives the valve rod rotation, makes piston be positioned at the top of valve body 14, and flap 12 drives support 9 and is rotated counterclockwise along bearing pin 8 under the Driving force of flowing medium, makes medium channel connect; If flowing medium refluxes, then medium inlet place instantaneous loss of pressure forms local negative pressure, and flap 12 is under the double action of the pressure that himself gravity and flowing medium reverse flow form, drive support 9 and turn clockwise, till flap 12 is pressed on the valve seat 13 along bearing pin 8.And the said multi-functional valve of the present invention also can utilize multi-functional valve to can be used as the characteristic of stop valve as safety check the time, forces non-return under system's band pressure operating mode.
3, realize the effect of modulating valve: 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 12 and valve seat 13 by adjusting handle.
Multifunctional valve structure compactness of the present invention, to close moment little, can be complete and open The energy that relies on pressure medium to produce. Compare with stop valve, its passage and pipeline axis direction are flat Row and isometrical with pipeline path, flow resistance is more much smaller than stop valve, almost can be considered zero; With accent The joint valve is compared, and advantage is more outstanding, and is not only simple, cheap for manufacturing cost than regulating valve structure, And can be implemented in that the flow to medium carries out step-less adjustment in the certain limit; Open with common revolving The formula check-valves is compared, and its check function is more reliable, in non-return action, not only can by The system media buffer brake reaches the effect of non-return, also can rely on the driving to handwheel, increases Seal pressure between valve sealing face, and then realize zero leakage.
