Abstract
A multi-joint screw thread water volume adjusting valve comprises a valve body, a locating cover arranged on the valve body, a valve pole connected with the locating cover by means of screwing connection. The valve pole which is sealed with the locating cover by double-channel sealing ring is connected with the locating cover by dicephalia or 3-joint screw thread. The utility model achieves easy adjustment of the valve pole when the hydraulic pressure is high, reduces the rotating torque of the adjustment by 40%-50%, and improves the airproof performance of the valve.
Description
The utility model relates to domestic gas-fired water heater, specifically refers to the water regulating valve in the domestic gas-fired water heater.
Water regulating valve in the domestic gas-fired water heater is generally regulated with voltage stabilizing two-part by the water yield and is formed.Wherein the water yield is regulated partly and generally is made up of valve body, valve rod and setting sleeve; Described valve body is provided with water intake, the water yield is regulated mouth, water outlet, and setting sleeve is fixed on the valve body, and the valve rod spiral shell is located in this setting sleeve.Adopt single screw thread to be spirally connected between present valve rod and the setting sleeve, and seal with " O " RunddichtringO, outwards release from valve rod with waterproof, valve rod rear end is the regulating handle part, and its front end is regulated a mouthful spool part for the water yield on the described valve body of sealing of regulating flow.Rotary valve rod can change spool and the distance of regulating mouth, thereby changes water flow; When Flow-rate adjustment mouth during by the spool planar surface encloses of valve rod front end, water can flow through from the central small hole on the valve rod, to keep its required minimum water flow under maximum temperature rise requires.
This valve can normally use under the lower situation of general hydraulic pressure, but when being used for hydraulic pressure when higher, just expose apparent in view shortcoming, as owing to adopt single screw thread to be spirally connected between valve rod and the setting sleeve, therefore feel is heavier when regulating valve stem, sometimes valve rod can produce and beat, and makes the water flow instability; Owing to only adopted a seal ring sealing, therefore between valve rod and setting sleeve, be easy to generate leakage.In view of tall building nowadays increases rapidly, high-pressure water pump uses increasingly extensive, thereby makes and show outstanding above-mentioned shortcoming day, has influenced product quality and performances.
The purpose of this utility model is by the improvement to the water regulating valve valve rod, proposes a kind of multiple thread water regulating valve, overcomes the shortcoming that the higher occasion of existing water regulating valve incompatibility hydraulic pressure is used.
A kind of multiple thread water regulating valve of the present utility model, comprise that mainly valve body, is fixed in the setting sleeve on the valve body, an and valve rod that is spirally connected with this setting sleeve, the jumping phenomena of the heavier and valve rod of feel adopts double end or 3 head threads to be spirally connected between described valve rod and the described setting sleeve when overcoming regulating valve stem.
In order to increase the sealability between setting sleeve and the valve rod, between setting sleeve and valve rod, adopt the sealing of double sealing circle.
Advantage of the present utility model is: when hydraulic pressure was higher, the feel of regulating valve stem obviously alleviated; Its moment of rotation can reduce 40～50%; The sealability of valve is obviously improved, when hydraulic pressure during at 2.6MPa, and no leakage phenomenon.Overcome the shortcoming of using under the former water regulating valve incompatibility hyperbaric environment.
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.
Fig. 1 is the schematic representation (the voltage stabilizing part is not shown) of the water regulating valve of present embodiment.
An embodiment of the present utility model as shown in Figure 1, this multiple thread water regulating valve mainly comprises valve body 1, valve rod 2 and setting sleeve 3, and described setting sleeve 3 is fixed on the valve body 1, and water enters in the valve body 1 from water intake 12, regulate mouth 11 through the water yield, flow to the voltage stabilizing part from water outlet 13.Adopt double end or 3 head threads 24 to be connected between valve rod 2 and the setting sleeve 3, the moment of rotation in the time of can reducing to regulate keeps the stable of stem position, and two seal rings of employing 4,5 seal between valve rod 2 and the setting sleeve 3, make the sealing between valve rod 2 and the setting sleeve 3 more complete.When spool 22 sealing regulated mouthfuls 11, flow control valve cut out, and this moment, water passed through from the central small hole 21.25 of valve rod 2, to keep the minimum water flow of water heater under maximum temperature rise requires.
Claims (2)
1. a multiple thread water regulating valve comprises that mainly a valve body, is fixed in the setting sleeve of this valve body, and a valve rod that is spirally connected with this setting sleeve, it is characterized in that between described valve rod and the described setting sleeve that employing double end or 3 head threads are spirally connected.
2. multiple thread water regulating valve according to claim 1 is characterized in that adopting between described valve rod and the setting sleeve 2 or 2 above seal ring sealings.
