Abstract
The utility model discloses a manual exhaust valve for radiators. The exhaust valve comprises a valve body mounted on a heating radiator; an exhaust hole is formed on the axial line of the valve body; an on-off device used for closing and opening the exhaust hole is arranged on the valve body, and comprises a valve rod; the valve rod is in clearance fit with the interior of the exhaust hole; the valve rod extends out of the valve body to be connected with a press button, and extends into the heating radiator to be connected with a primary air block; the valve rod returns due to unidirectional force applied by an elastic element; the stress direction of the valve rod is from the interior of the heating radiator to the exterior of the valve body; when the valve rod returns, the exhaust hole is blocked up through the primary air block, and a pressing opening distance is kept between the press button and the valve body; the exhaust hole also can be formed as a stepped hole; the valve rod is a stepped shaft matched with the stepped hole; and a secondary air block is formed at the stepped position of the stepped shaft. The utility model provides a pressing exhaust valve which has the advantages that when degassing is required, all that is needed is to press the press button; and the operation is convenient without any tool, thereby effectively preventing water from splashing, and guaranteeing safe use.
Description
(1) technical field:
The utility model relates to the warming installation parts, is a kind of radiator manual exhaust valve that is used on the radiator specifically.
(2) background technique:
The China north general hot-water circulation heating system that uses in winter, each user terminal is the radiator of heat transmission, owing to may be mixed with air in the hot water of line transportation, when air is blocked in the radiator, can the radiating efficiency of radiator be impacted, therefore radiator is provided with an outlet valve, with air unnecessary in the radiator of draining, recovers the radiator heat sinking function.
Outlet valve commonly used at present is the screw-type manual exhaust valve, and the valve body of outlet valve is tightened on the relief opening of radiator, and what cooperate in the screw thread exhaust port of valve body is screw, stops up exhaust port during screw-driving, unscrews screw and opens the exhaust port venting.
The defective of finding the screw-type manual exhaust valve in the practice is:
1, turning screw needs special tool, and the user need be equipped with these instruments, may also will seek during use temporarily, causes trouble to the user.
2, inconvenience during specific operation, how the degree that screw turns has determined the size of air displacement, it is low that screw is unscrewed degree, discharge quantity is not enough, and deflation time is long, and it is excessive that screw is unscrewed degree, hot water discharges of also thereupon splashing in venting causes to scald to the operator and endangers.
The scratch sealing surface easily that rotatablely moves repeatedly of 3 screws, thus outlet valve was lost efficacy.
(3) model utility content:
At the deficiency of conventional screw formula manual exhaust valve, the utility model has designed a kind of easy and simple to handle, radiator manual exhaust valve that Safety performance is good.
Can realize the radiator manual exhaust valve of above-mentioned purpose, comprise the valve body that is installed on the radiator, offer exhaust port on the shaft axis of valve body, the start-stop device of closing and open exhaust port also is set on the valve body, different is that described start-stop device comprises valve rod, and valve lever clearance is matched with in the exhaust port, and the gap between valve rod and the exhaust port is an air outlet flue, one end of valve rod is stretched in valve body and is connected knob outward, and it is stifled that the other end of valve rod is stretched in the one-level gas that connects seal vents in the radiator; Valve rod is by the unidirectional application of force return of elastic element, valve rod be subjected to force direction be in the radiator outside valve body, the stifled seal vents of one-level gas during the valve rod return, start-stop device is for closing, press knob, valve rod overcomes the active force of elastic element, and the stifled exhaust port of opening of the one-level gas of valve rod is exitted.
Exhaust port can be offered the step hole that reduces for along valve rod return direction size, the stifled interior sealed step small diameter bore of step large diameter hole that is hidden in of described one-level gas.
For further improving sealing effect, it is stifled that secondary gas can be set, and its structure also is that exhaust port is arranged to step hole, press valve rod return direction, the diameter of step hole reduces, and the valve rod of corresponding matching is the step axle, and the step position of step axle is stifled to the step hole formation secondary gas of minor diameter.
One-level gas is stifled can be formed by large-sized valve rod axle head, this valve rod axle head diameter is greater than the step large diameter hole, the valve rod axle head is provided with seal ring with the end face that contacts of valve body, and seal ring also is arranged on the step position of described step axle and contacting on the end face of step small diameter bore.
A kind of pressure spring that is chosen as of described elastic element, valve rod places in the pressure spring, and the pressure spring pretension is between valve body and knob.
Select for use at elastic element under the situation of pressure spring, described start-stop device can be set to concealed structure, is about to knob and is hidden in the valve body, and concrete structure is inwardly to offer coaxial blind hole on valve body, and knob is placed blind hole.
For avoiding the misoperation of knob and making outlet valve more attractive in appearance, valve gap can be set on valve body, valve gap is installed in the blind hole mouth of valve body, knob is closed in the valve body it is protected, and takes off valve gap when needing venting and presses knob and get final product.Advantage of the present utility model:
1, the utility model radiator manual exhaust valve is the push type outlet valve, as long as need press knob during venting, need not any instrument, and is easy to operate.
2, configure gap length between valve rod and the exhaust port, can determine constant safety discharging air amount, can prevent splashing of hot water during exhaust, guarantee personal safety.
(4) description of drawings:
Fig. 1 is the structural representation of a kind of mode of execution of the utility model.
Figure number sign: 1, valve body; 2, valve rod; 3, knob; 4, pressure spring; 5, valve gap; 6, seal ring; 7, one-level gas is stifled; 8, secondary gas is stifled.
(5) embodiment:
The unidirectional non-return radiator of the utility model manual exhaust valve comprises valve body 1 and valve rod 2.
Valve body 1 is threaded with the mounting hole of radiator, valve body 1 end face that contacts with radiator is provided with O RunddichtringO 6, offer exhaust port on the shaft axis of valve body 1, this exhaust port is a step hole, it is little that the bottom outlet of step hole is gone up the hole greatly, and coaxial blind hole is inwardly offered in valve body 1 upper-end surface, inwardly offers the coaxial annular groove on the basis of blind hole again, pressure spring 4 is set, as shown in Figure 1 in the circular trough.
Valve rod 2 is the step axle with the step hole Spielpassung, its upper end is stretched in blind hole and is connected with round plastic knob 3 coaxial threaded, and carry out fastening with the screw thread retaining rubber, between knob 3 and circular trough bottom, the blind hole mouth of knob 3 tops is installed with valve gap 5 to knob 3 after the connection in blind hole and with pressure spring 4 pretensions; Stretch in radiator the lower end of valve rod 2, and its axle head diameter dimension increases that to form one-level gas stifled 7, and the size of one-level gas stifled 7 is greater than the bottom outlet of step hole, and one-level gas stifled 7 is provided with O RunddichtringO 6 with the end face that contacts of valve body 1; It is stifled 8 that the last hole of the step position of step axle and step hole forms secondary gas, and secondary gas stifled 8 is provided with seal ring 6 with the end face that contacts of step hole, as shown in Figure 1.
