Abstract
The utility model relates to an orifice type regulating valve used for regulating in the high-temperature, high-pressure and middle and small caliber pipe line. The orifice type regulating valve is characterized in that the inner part of the valve body is provided with two valve plates with identical number of orifice, and the two valve plates which has one-to-one correspondence can move relatively; the orifice type regulating valve can realize the goal of linear current-regulating and wide and stable current-regulating range under, driving by a transmission mechanism. The utility model can also be used as a flowmeter and automation element to use.
Description
The utility model relates to a kind of valve that is used to regulate on high temperature, high pressure, middle small pipe-line, particularly be used to adjust thermally equilibrated valve in heat network system.
At present, be used to transfer the valve of stream on high temperature, high pressure, middle small pipe-line, majority is a stop valve.Because internal structure can be considered seat and the relation of covering, the quality that makes it valve increases, and volume increases, and particularly control characteristic is poor, makes it to be difficult to balance in adjusting pipe network flow, pressure and other parameters work.Even generation is significantly cold and hot outstanding poor, considers this factor that is difficult to overcome during engineering design, often makes basic parameters selection excessive, causes wasting energy and improving engineering cost.
In order to overcome the deficiency in the above-mentioned technology, the utility model will provide that a kind of volume is little, light weight, high temperature resistant, high pressure resistant, control characteristic is good, be suitable in the orifice-plate type modulating valve that uses on the small-bore pipeline.
The purpose of this utility model will reach by following measure, promptly in valve body (2) by the fixing a slice fixedly orifice plate (4) with holes of pin (A), by bridge screw (B), pressing plate (7) and circlip (3) fixedly a slice with fixedly orifice plate (4) hole count is identical, and removable orifice plate (5) one to one, be provided with removable orifice plate (5) in the outside of valve body (2) and directly connect, and be subjected to hand, the driving mechanism (6) that Electric actuator (8) drives, also be provided with one group of positioning work piece (1) that is used to control the removable orifice plate stroke in the bottom of valve body (2), this positioning work piece is made up of screw rod (E) that is screwed into valve body (2) bottom and external nut (F).
Fixedly orifice plate (4) and removable orifice plate (5) are all selected high temperature resistant, corrosion resistant metal for use or are nonmetally made garden shape or square, have hole onesize more than three (D, C) on its plane, for considering to reduce the inlet resistance, the hole (C) of its removable orifice plate (5) can be made into taper, the diameter in its hole and number can require to determine according to controlled plant.
Circlip (3) is selected good springiness, high temperature resistant, corrosion resistance material for use, makes a kind of ring with flute profile, thereby can realize that two orifice plates when dislocation relatively takes place, keep closely cooperating.
Driving mechanism (6) is according to different mode of operation requirements, and its inside can be made into link rod structure or makes the gear type structure, makes its removable orifice plate (5) moving linearly or garden Zhou Yundong, thus the purpose that realizes changing flow resistance and transfer stream.
The drawing explanation of accompanying drawing:
Fig. 1 is the structural representation of orifice-plate type modulating valve
1 is positioning work piece among the figure, and 2 is valve body, and 3 is circlip, and 4 are fixing orifice plate, and 5 is removable orifice plate, 6 is driving mechanism, and 7 is pressing plate, and 8 is hand, Electric actuator, and A is a pin, and B is a bridge screw, C is the hole on the removable orifice plate, and D is the hole on the fixing orifice plate, and E is a screw rod, and F is an outer nut.
Below in conjunction with one of them embodiment shown in the drawings the utility model is described further: the problem that the stop valve structure size is big, control characteristic is poor in order to solve, be difficult to realize the reasonable control of parameter, according to two mutual changing of the relative positions of plate with holes, change the reason of flow area and flow resistance, the seat and the circulation relationship of lid of past stop valve is modified into the multi beam type of flow in the logical cross section of adjustable rectification.Therefore, but the two porous plates of setting relative movement is formed valve plate in valve body, can realize manually and the motorized adjustment flow by hand, Electric actuator, realizes purpose of the present invention.
The utility model compared with prior art has following advantage:
1, owing to adopt the porous plate that can be movable relatively as valve plate, so improved control characteristic, reaches approximately linear and transfer stream and transfer stream wide ranges and stable requirement.
2, because the utility model is to be made by heat-resisting, corrosion resistant metal or nonmetallic materials, thus be best suited in use in the pipe network of small-bore, high pressure, high-temperature.
3, because therefore the utility model compact conformation has the characteristics that quality is light, volume is little, cost is low.
Claims (5)
1, a kind of orifice-plate type modulating valve of forming by valve body (2), hand, Electric actuator (8), it is characterized in that in valve body (2), by the fixing a slice fixedly orifice plate (4) with holes of pin (A), by fixing a slice and the removable orifice plate (5) one to one identical of bridge screw (B), pressing plate (7) and circlip (3) with fixing orifice plate (4) hole count, also be provided with removable orifice plate (5) in the outside of valve body (2) and directly connect, and the driving mechanism (6) that driven by hand, Electric actuator (8), also be provided with one group of positioning work piece (1) in the bottom of valve body (2).
2, orifice-plate type modulating valve according to claim 1 is characterized in that said fixedly orifice plate (4) and removable orifice plate (5) adopt high temperature resistant, corrosion resistant metal or nonmetallic material to make garden shape or square, its plane has hole onesize more than three (D, C).
