Abstract
The utility model discloses a flow-control water distributor, which comprises a valve stem nut and a valve stem. The valve stem nut is arranged in a valve stem mounting channel, the middle of the valve stem is provided with a circle of threads, a circle of threads is arranged inside the valve stem nut, the thread pitch of the threads is equal to the distance from a sealing surface to a lower surface of a valve spool in a full-open state, the threads are disposed on the valve stem, and the thread pitch of the threads is equal to the distance from the sealing surface to the lower surface of the valve spool in the full-open state. By the aid of the flow-control water distributor with the structure, water outlet flow of a water outlet channel can be accurately controlled from being closed to being opened to the maximum flow by rotating the valve stem by 360-degree on the valve stem nut at the most, thereby being extremely convenient in operation.
Description
Technical field
The utility model relates to the Flow-rate adjustment technology of water knockout drum in the temperature control system, more particularly, relates to a kind of flow control water knockout drum.
Background technique
In floor heating system, air-conditioner water system or other industrial water system, all can use the device of joining, catchmenting that connects each road heating pipe confession, backwater with flow control, be commonly referred to as flow control water collecting and diversifying device or condensate correcting-distribuing device, be commonly called as the flow control water knockout drum.Divide, water-collecting machine is to consider pressure balance between each minute ring loop and function of use and having all of being provided with pressed, shunted, the common vessel of interflow, uniform voltage function in a closed Water System.Branch, water-collecting machine are the intermediate conversion nodes between low-temperature receiver side and load side, form a connecting link, digest, typical case's application scenarios be exactly in building, utilize to divide, water-collecting machine carries out the branch ring to difference towards the zone of, difference in functionality, divides the loop of ring still to be in a complete closed Water System through undue, water-collecting machine.The flow control water knockout drum comprises having the intake tunnel that is interconnected in the prior art, exhalant canal and valve rod are installed passage, valve rod install passage be positioned at exhalant canal directly over, and exhalant canal and valve rod are installed passage and are positioned at substantially on the straight line, valve rod is installed the interior Stem Mut of passage by the screw thread at valve rod middle part with valve rod and is connected, the upper end of valve rod is provided with interior hexagonal flow control valve, the lower end of valve rod is provided with spool, make valve rod on Stem Mut, rotate by regulating flow control valve, thereby drive spool and regulate the size of aperture with respect to the lifting of exhalant canal sealing surface, realize water knockout drum from the complete shut-down degree to the flow control the full gate.And in the process of installing with regular maintenance, need the flow of water knockout drum be adjusted, because valve rod can rotate multi-turn and even ten circles on Stem Mut, so it is still difficult to control the percentage of water flow accurately.
The model utility content
At the problem that can not well accurately control the water flow of water knockout drum that exists in the prior art, the purpose of this utility model provides a kind of flow control water knockout drum, can realize accurately carrying out flow control.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of flow control water knockout drum comprises that being located at valve rod installs the screwed valve rod of Stem Mut and middle part in the passage, and the thread turns in the described Stem Mut is a circle, its pitch with sealing surface during to full gate the distance below the spool equate; Thread turns on the described valve rod is a circle, its pitch with sealing surface during to full gate the distance below the spool equate.
Described valve rod is installed passage and is provided with the flow percentage scale.
Described valve rod is installed the passage top and also is provided with protecting cover.
Compared with prior art, adopt a kind of flow control water knockout drum of the present utility model, comprise that being located at valve rod installs the interior screwed valve rod of Stem Mut and middle part of passage, thread turns in the described Stem Mut is a circle, its pitch with sealing surface during to full gate the distance below the spool equate; Thread turns on the described valve rod is a circle, its pitch with sealing surface during to full gate the distance below the spool equate.By adopting said structure, make valve rod on Stem Mut, revolve three-sixth turn at the most, the water flow that just can control exhalant canal accurately is by being closed to maximum, and it is very convenient to operate.
Description of drawings
Fig. 1 is the broken section structural representation of a kind of flow control water knockout drum of the present utility model;
Fig. 2 is the broken section structural representation when spool and sealing surface closed state among Fig. 1.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 1, a kind of flow control water knockout drum shown in Figure 2, comprise housing 11, be provided with the intake tunnel 12 that is interconnected in the housing 11, exhalant canal 13 and valve rod are installed passage 14, valve rod install passage 14 be positioned at exhalant canal 13 directly over, and exhalant canal 13 is installed passage 14 with valve rod and is positioned at substantially on the straight line, valve rod 15 screw thread by valve rod 15 middle parts and valve rod are installed passage 14 interior Stem Muts 16 and are connected, the upper end of valve rod 15 is provided with interior hexagonal flow control valve 17, the lower end of valve rod 15 is provided with spool 18, thread turns in the Stem Mut 16 are a circle, its pitch with exhalant canal 13 upper end sealing surfaces 131 during to full gate the distance below the spool 18 equate; Thread turns on the valve rod 15 is a circle, its pitch with sealing surface 131 during to full gate the distance below the spool 18 equate.For more intuitive reflection flow control valve 17 for the control of water flow, can be provided with the flow percentage scale in the upper end that valve rod is installed passage 14.As further improvement, can also above installing passage 14, valve rod add protecting cover 19, in order to protection flow control valve 17.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, all will drop in the scope of claim of the present utility model the above embodiment's variation, modification.
