Abstract
A flow regulating valve is characterized by comprising a valve body, a flow regulating board, a bearing, a lower cover, an O-shaped sealing ring, a sealing cushion and an electric actuator, wherein the valve body is provided with a water inlet and a water outlet in the horizontal direction, the flow regulating board is arranged inside the valve body, a rotary shaft at the upper end of the flow regulating board is sleeved with the O-shaped sealing ring rotationally matched with a shaft hole in the valve body, the lower end of the flow regulating board is rotationally matched with the bearing arranged on the lower cover, the lower cover is fixedly connected with the sealing cushion through the valve body, and the rotary shaft at the upper end of the flow regulating board is fixedly connected with the electric actuator. The flow regulating valve has the advantages that the full drift diameter and large flow are achieved, and pressure loss is achieved; the flow regulating board and the rotary shaft are of an integrated structure, and using reliability is achieved; a gap between the flow regulating board and the valve body can be freely set so that the regulating valve can keep definite discharging flow in a closed state, and a pipeline is prevented from being frozen; as the certain gap is formed between the flow regulating board and the valve body, the situation that the valve body rusts and flow regulation can not be conducted can be prevented.
Description
Technical field
The utility model relates to valve technology field, is the flow regulator that a kind of heating field is used.
Background technique
In China, heat metering reform is the water that continues, electricity, after combustion gas implements to press meterage, the field that last is not charged by metering, along with the propelling of national energy-saving emission reduction work, the installation of hot measuring products is increasing, in order to realize energy-saving and emission-reduction, the device that must supporting installation can be used for Flow-rate adjustment is installed after heat metering device, so that need to the room temperature of oneself be regulated according to oneself later, reach energy-conservation object, at present, what matched with hot measuring apparatus used mainly contains two kinds of valves, one is electric heating stop valve, one is electric ball valve, these two kinds of valves all exist fatal defect in actual use, electric heating stop valve, the aperture of valve is little, the pressure loss is large, and easily stop up, the spheroid of electric ball valve and the close drive fit of the Sealing at two ends, need to lean on the Sealing on both sides to clamp Sphere orientation, therefore, in heating system, use very easily stuck by foreign material, particularly use to produce fouling after certain time limit and cause valve rust dead, cannot normally work, in addition, spheroid in valve and the rotatingshaft of valve are split, and spheroid becomes rusty, and after death rotatingshaft is very easily stubborn bald.Therefore, be badly in need of a kind of special valve that is specifically designed to heat metering field, promote the popularization of hot gage work.
Model utility content
The purpose of this utility model is for the deficiencies in the prior art, and a kind of simple in structure, multiple functional, service-strong regulates room temperature flow control valve for hot user is provided.
Realizing the technological scheme that above-mentioned purpose takes is: a kind of flow control valve, it is characterized in that, it comprises: valve body, flow is adjusted plate, bearing, lower cover, O RunddichtringO, sealing gasket and electric actuator, in the substantially horizontal of valve body, water intake and water outlet are set, be built-in with flow at valve body and adjust plate, the axis hole that is nested with O RunddichtringO and valve body on the running shaft of flow adjustment plate upper end is rotatably assorted, flow is adjusted the lower end of plate and the bearing of lower cover setting is rotatably assorted, lower cover and valve body are connected by sealing gasket, running shaft and electric actuator that flow is adjusted plate upper end are connected.
A kind of flow control valve of the utility model has the following advantages:
1, the large flow of full-bore, the pressure loss is little;
2, flow is adjusted plate and running shaft integrative-structure, uses reliable;
3, the gap that flow is adjusted between plate and valve body can be set arbitrarily, can make modulating valve under the state of closing, also can keep certain letdown flow, prevents that pipeline from being frozen;
4, owing to existing certain gap can prevent that valve body rust is dead between flow adjustment plate and valve body, cannot carry out Flow-rate adjustment.
Accompanying drawing explanation
Fig. 1 is a kind of flow control valve structure schematic diagram of the present utility model;
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1;
Fig. 3 is the structural perspective that flow is adjusted plate 2.
In figure: 1 valve body, 2 flows are adjusted plate, 3 bearings, 4 lower covers, 5 seal rings, 6 sealing gaskets, 7 electric actuator.
Embodiment
The utility model is described in further detail to utilize the drawings and specific embodiments below.
With reference to Fig. 1-3, a kind of flow control valve of the present utility model, comprise: valve body 1, flow is adjusted plate 2, bearing 3, lower cover 4, O RunddichtringO 5, sealing gasket 6 and electric actuator 7, in the substantially horizontal of valve body 1, water intake and water outlet are set, be built-in with flow at valve body 1 and adjust plate 2, on the running shaft of flow adjustment plate 2 upper ends, being nested with O RunddichtringO 5 is rotatably assorted with the axis hole of valve body 1, flow is adjusted the lower end of plate 2 and the bearing 3 that lower cover 4 arranges is rotatably assorted, lower cover 4 is connected by sealing gasket 6 with valve body 1, running shaft and electric actuator that flow is adjusted plate 2 upper ends are connected.The running shaft that flow is adjusted plate 2 and upper end is structure as a whole.
The baffle part that the flow of a kind of flow control valve for heating field of the utility model is adjusted plate 2 is eccentric structure, when valve closing, valve body 1 water intake can be shut, when valve open, the eccentric baffle plate of flow adjustment plate 2 is amesiality, flow channel is got out of the way, reach the object that reduces resistance.Valve body 1 inner chamber radius should be slightly larger than the turning radius of flow adjustment plate 2, and the gap between assurance valve body 1 inner chamber and flow adjustment plate 2 is at 0.2～1.0mm.When valve is during in closed condition, should there is certain leakage rate; Flow is adjusted plate 2 and is passed through its rotating shaft and following well centering of bearing 3 realizations, guarantees that the gap between valve body 1 inner chamber and flow adjustment plate 2 is constant.The good seal for the axis hole of valve body 1 and flow are adjusted between the running shaft of plate 2 upper ends, between lower cover 4 and valve body 1, the material of O seal ring 5, sealing gasket 6 is ethylene propylene diene rubber.Electric actuator is commercially available prod.
After a kind of flow control valve of the present utility model is arranged in user's heat supplying pipeline, user can set own room temperature according to the needs of oneself, is completed the unlatching of valve or is closed, the regulation and control of realization to user indoor temperature by electric actuator.
