Abstract

The utility model relates to a pressure stabilizer of water supply, which comprises a joint provided with an inlet and an outlet; a throttle lever is arranged on a flow passage in the joint; the throttle lever is stretched out the joint and connected with an elastic corrugated sheet; a pressure chamber composed of the elastic corrugated sheet and an external cover is communicated with a passage at the outlet end; one end cap which is matched with the screw of the external cover is arranged outside of the external cover; the elastic corrugated sheet is pushed against the end cap through a push rod and a spring. The stabilizer has the advantages of simple and reasonable structure, low cost, favorable pressure adjusting and stabilizing performance, convenient use, and reliable running; besides, the utility model is suitable for widespread installation for all users.

Description

User's tap water voltage stabilizer

The utility model relates to a kind of user's tap water voltage stabilizer, belongs to a kind of waterway fitting.

The device of regulating the liquid supply pressure in the prior art is a lot, for example be used on the pneumatic-typed water feeder of high-floor feedwater, its structure and principle are all very complicated, but the stable-pressure device that is used on the tap water pipe line only occurs at Chinese patent 93205931, this voltage stabilizer has adopted hydraulic pressure sensor, controller and solenoid valve, structure is very complicated, be unsuitable for vast tap water user and popularize use, and in actual life, the tap water pressure difference that the user accepted of different story heights, low layer user tap water pressure height often appears, water utter long and high-pitched sounds often (cavitation erosion), water consumption is big, and the situation of the not enough or anhydrous supply of pressure of supply water then appears in high-rise user, especially under the meticulous situation of rush hour of water or pressure of supply water deficiency or water supply line, the pressure difference that height difference is brought and more obvious for the difference of stream ability is brought very big inconvenience to resident living.

The purpose of this utility model is to overcome the deficiencies in the prior art and provides simple in structure, cheap, voltage regulation performance is good, has the self-regulating ability, is suitable for whole users and popularizes a kind of user's tap water voltage stabilizer of installing.

User's tap water voltage stabilizer of the present utility model, the joint that comprises a discharge pressure fluid, have import and outlet on the joint, be interconnected between import and the outlet, it is characterized in that having a throttle valve plate or throttling rod on the communication passage between import in the joint and the outlet, throttle valve plate or throttling rod stretch out outside the joint and join with elastic corrugated, elastic corrugated pressure chamber that constitutes with enclosing cover is connected with the passage of outlet end, enclosing cover is equipped with an end cap outward, end cap and enclosing cover screw-thread fit, elastic corrugated withstands on the end cap by push rod and spring.

User's tap water voltage stabilizer of the present utility model, simple and reasonable for structure, cost is low, and the performance of adjustment and steady pressure is good, easy to use, reliable, can be made into a water channel standard piece, is suitable for whole users and popularizes installation.

For introducing user's tap water voltage stabilizer of the present utility model in detail, be elaborated below in conjunction with accompanying drawing:

Fig. 1 is the sectional structure schematic representation of user's tap water voltage stabilizer of the present utility model.

Referring to Fig. 1, user's tap water voltage stabilizer of the present utility model, the joint 1 that comprises a discharge pressure fluid, have import 2 and outlet 3 on the joint 1, import 2 and export 3 between be interconnected, it is characterized in that import 2 in the joint and export on the communication passage 4 between 3 to have a throttle valve plate or throttling rod 5, throttle valve plate or throttling rod 5 stretch out outside the joint 1 and join with elastic corrugated 6, be connected with the passage that exports 3 ends with pressure chamber 8 that enclosing cover 7 constitutes for elastic corrugated 6, the enclosing cover 7 outer end caps 9 that are equipped with, end cap 9 and enclosing cover 7 screw-thread fit, elastic corrugated 6 withstands on the end cap 9 by push rod 10 and spring 11.

Its working principle is: user's tap water enters joint 1 from import 2, flow to outlet 3 through the passage between import 2 and the outlet 3, the pressure that exports 3 ends is delivered in elastic corrugated 6 pressure chamber 8 that forms with enclosing cover 7 by pressure transmission hole 14 or external pressure transmission pipeline 13, the depth that the adjustment end cap is screwed on enclosing cover 7 can be used for setting the pressure of outlet 3, if the pressure of outlet 3 ends is lower than the value that sets, then the pressure in the pressure chamber 8 reduces, elastic corrugated 6 evagination, the drive throttling rod is overhanging, the pressure that throttling reduces until outlet 3 and pressure chamber 8 is raised to setting value, otherwise, pressure chamber's pressure height, impel throttling rod descending, play the effect of voltage stabilizing like this to increase throttling.

For increasing the sensitivity of throttling action, can make a joint trunnion to import 2 and the communication passage 4 that exports between 3.

Elastic corrugated 6 with joint 1 between cavity 12 preferably be communicated with atmosphere by pore 15, should install seal ring between throttle valve plate or throttling rod 5 and the joint this moment.
