Abstract
The utility model relates to a flow control device, which is widely used in fluid pipeline systems, such as the heat supply and the refrigerating engineering, etc. For the flow rate balance and the stable running of all section systems, and suitable temperature in each room, a flow stopping device is necessary to be arranged on each pipeline. The utility model relates to a flow stopping adjustable valve. The position of the flow stopping hole of the flow stopping adjustable valve can deviate from a centre line 0-0 and the other flow stopping hole can be converted to aim at the direction (A direction) of the opening of a water inlet pipeline. Therefore, the optimal adjusting effect can be obtained in the heat supply and the refrigerating fluid pipelines. Simultaneously, a dirt removing mechanism is also arranged in the flow stopping adjustable valve. The flow stopping adjustable valve having cheap price is suitable for middle and lower-grade constructions.
Description
The utility model relates to a kind of flow regulator, it is widely used in the fluid piping systems such as heat supply, refrigeration engineering, and is in order to make each loop systems flow equilibrium, stable, it is suitable to reach each room temperature, and it is very necessary that choke apparatus is set on each pipeline.
Present a part of heating, air conditioner refrigerating pipe-line system still adopt stop valve or gate valve or ball valve to come the pilot line flow, and this class valve only works to cut out flow, can not reach the purpose of regulating flow.Perfect day by day along with fluid piping system, many heating, air conditioner refrigerating pipe-line system have adopted technical fixed choking coil, this device is to fix a choking coil with two flange plate, and be arranged between two pipes of disconnection, by the pipe-line system assignment of traffic, calculate required pore size and determine the choking coil aperture dimension, regulate each loop systems flow, make it balance thereby reach.The fixed choking coil of this special use is simple in structure, and resistance flowing effect is still good, and is simultaneously economical and practical.In fact, pipe-line system can not be determined by theoretical calculating fully, so still have the following disadvantages:
1) restricted orifice size and position are all fixed, and can't change, and the calculated value in restricted orifice aperture when difference occurring with actual user mode, can't change, and the pipe-line system flow can not get rational adjusting.
2) after restricted orifice is stopped up by incrustation scale, iron rust and other accumulation of impurities, be difficult to remove, have only fixing choking coil is disassembled, just can reach the purpose of elimination dirt.
In view of this, the purpose of this utility model is to propose a kind of choked flow modulating valve at the defective of above-mentioned existing fixed choking coil existence, it can change the restricted orifice aperture, make flow system flow reach balance, be convenient to remove dirt,, can obtain splendid regulating effect in the fluid circuit of refrigeration in heat supply.This system can make the energy be used adequately reasonably, and system is reliable, therefore, has fully satisfied the mixed economy effect of energy saving.In addition, choked flow modulating valve itself is cheap, is suitable for low and middle-grade buildings and adopts.
In order to realize the purpose of this utility model, of the present utility modelly be characterised in that it comprises: valve body (1), be arranged between the valve body manhole appendix, and can be around the choked flow modulating valve (2) of the rotational of vertical manhole appendix center line O-O, be fixed on the adjustment seat (3) of valve body top, be fixed on the sealing seat (4) of adjustment seat top, place the spunyarn Sealing (5) in the sealing seat, pass the spunyarn Sealing, adjustment seat is inserted the interior adjustable lever (6) of square hole of choked flow modulating valve at last, be fixed on the blowdown plug (7) of valve body below, the garden side face of choked flow modulating valve (2) is provided with restricted orifice.
Further feature of the present utility model is: the garden side face of choked flow modulating valve (2) is provided with the restricted orifice in the two about 90 ° different apertures that are separated by, and being separated by respectively 180 ° with two restricted orifice is provided with two caliber holes.
Fig. 1 is a structural representation of the present utility model.
It is as follows to be described in detail an exemplary embodiments of the present utility model below with reference to Fig. 1:
Be applied in one two logical choked flow modulating valve in the heating system, on the D=37 millimeter circumference of choked flow modulating valve (2), be separated by about 90 ° and locate to be provided with two hole D1, D2, in the caliber D=15-50 millimeter scope that valve body (1) connects, restricted orifice aperture D=3,4,5,6,7,8,9,10,11,12,15,18,20(millimeter commonly used) etc. 12 kinds.By theoretical calculated hole diameters D, choose two kinds of aperture D1, D2 near D, be arranged on the circumference of the choked flow modulating valve (2) of being separated by about 90 °, with D1, the D2 180 ° of holes that two caliber D are set that are separated by respectively, for example: theoretical calculation goes out aperture D=6.2 millimeter, the D1=6 millimeter, the hole of D2=7 millimeter is in the face of intake pipe road junction direction (A to), but center, D2 hole is center line O-O slightly relatively, to guarantee that the actual flow passage is more near the D=6.2 millimeter, by changing the restricted orifice of off-centered position of restricted orifice and replacing another location, reach the adjusting flow.Spunyarn Sealing (5) prevents the required sealing of adjustable lever (6) running clearance, sealing seat (4) is that the thick sealing of fixed oil is used, adjustment seat (3) is the radial support that rotates as adjustable lever (6), the square toes of adjustable lever (6) match with square hole on the choked flow modulating valve (2), the end face that adjustable lever (6) garden post part links to each other with square toes, as the axial shoulder of adjustable lever, be supported in choked flow modulating valve (2) end face.When needing blowdown,, after removing finishes blowdown plug (7) is restored as long as blowdown plug (7) is unloaded (scyewed joint) from valve body lower portion; Need to take out choked flow modulating valve (2) (repair or change), adjustment seat (3) together with all parts in addition on it, is unloaded (microgroove connections) from valve body (1), with in band iron and steel wire insertion choked flow modulating valve (2) square hole, just can take out the choked flow modulating valve then.
Claims (2)
1, a kind of choked flow modulating valve, it is characterized in that it comprises: valve body (1), be arranged between the valve body manhole appendix, and can be around the choked flow modulating valve (2) of the rotational of vertical manhole appendix center line zero-zero, be fixed on the adjustment seat (3) of valve body top, be fixed on the sealing seat (4) of adjustment seat top, place the spunyarn Sealing (5) in the sealing seat, pass the spunyarn Sealing, adjustment seat is inserted the interior adjustable lever (6) of square hole of choked flow modulating valve at last, be fixed on the blowdown plug (7) of valve body below, the garden side face of choked flow modulating valve (2) is provided with restricted orifice.
