Technical Field

The invention relates to the field of valve cores of balance valves, in particular to a plug-in type dynamic flow balance valve core.

Background

At present, the hydraulic balance problem exists in an air conditioning heating system and a domestic water system, so various dynamic flow balance valves are researched and developed to solve the problem. However, the price of the dynamic flow balance valve which is popular in the market is high, and the dynamic flow balance valve cannot reach the level which is generally accepted by people; can produce a novel dynamic balance valve core which can be used in a pipeline system without a dynamic flow balance valve to solve the problem of hydraulic balance and has low price to achieve the purposes of comfort and energy saving? This is a common concern. Accordingly, the present invention provides a cartridge for a plug-in dynamic flow balancing valve that solves the above-identified problems.

Disclosure of Invention

The present invention is directed to a valve core of a plug-in dynamic flow balance valve, so as to solve the problems mentioned in the background art.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a bayonet dynamic flow balance valve case, includes tripod, accuse water slider, case shell, stainless steel spring, guide bar, fastening nut and curved surface, the case sets up the guide bar in class, and the guide bar surface left part sets up fastening nut, and guide bar and fastening nut threaded connection, and the guide bar surface right part sets up the accuse water slider, the right-hand tripod that sets up of accuse water slider, and the stainless steel spring is established to the guide bar surface cover, and case shell inner wall establishes to the curved surface.

As a further scheme of the invention: one end of the stainless steel spring is propped against the water outlet end of the valve core shell.

As a still further scheme of the invention: the other end of the stainless steel spring is propped against the water control sliding block.

As a still further scheme of the invention: the other end of the water control slide block is propped against the tripod.

As a still further scheme of the invention: the tripod is fixed on the water inlet port of the valve core shell.

As a still further scheme of the invention: the guide rod is propped against the water inlet end of the tripod.

Compared with the prior art, the invention has the beneficial effects that:

the invention has simple structure and convenient installation, and not only achieves the purposes of hydraulic balance and comfort of the system, but also achieves the purpose of energy conservation.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 5, in an embodiment of the present invention, an inserted dynamic flow balance valve core includes a tripod bracket 1, a water control slider 2, a valve core housing 3, a stainless steel spring 4, a guide rod 5, a fastening nut 6 and a curved surface 7, a guide rod 5 is arranged in the valve core 1, a fastening nut 6 is arranged at the left part of the outer surface of the guide rod 5, and guide bar 5 and fastening nut 6 threaded connection, guide bar 5 surface right part sets up accuse water slider 2, accuse water slider 2 right-hand three-legged support 1 that sets up, guide bar 5 surface cover establishes stainless steel spring 4, the one end of stainless steel spring 4 supports the valve core shell 3 and goes out the water end, the other end of stainless steel spring 4 supports accuse water slider 2, the other end of accuse water slider 2 supports three-legged support 1, three-legged support 1 is fixed on the 3 water inlet ports of valve core shell, guide bar 5 supports three-legged support 1 and advances the water end, 3 inner walls of valve core shell establish to curved surface 7.

The working principle is as follows: within the pressure difference range of 30Kpa-300Kpa, when the pressure difference between the right end (water inlet end) and the left end (water outlet end) of the water control slide block 2 becomes larger, the stainless steel spring 4 contracts leftwards, the water control slide block 2 moves leftwards, and the water flowing area of the curved through hole is reduced, according to the principle that(G-flow, xi-flow coefficient, A-water flow area, delta p-pressure difference), the value of the flow G (G is more than or equal to 0.3 and less than or equal to 0.8m3/h) is kept unchanged, when the pressure difference between the right end (water inlet end) and the left end (water outlet end) of the water control slide block 2 is reduced, the stainless steel spring 4 stretches towards the right, the water control slide block 2 moves towards the right, and the water flow area between the curve 7 and the water control slide block 2 is increased according to the principle thatThe values of (G-flow, xi-flow coefficient, A-water flow area, delta p-pressure difference) and the flow G (G is more than or equal to 0.3 and less than or equal to 0.8m3/h) are also kept unchanged, so that the hydraulic balance and comfort of the system are realized, and the energy-saving purpose is realized.

How can the values of 7x (mm) and d (cm) be calculated for comfort and energy saving?

The calculation method comprises the following steps:

the design flow Q (m3/h), the total stroke L (mm), the outer diameter d (cm) of the water control slide block (2), the stroke y (y is more than or equal to 0 and less than or equal to L), and the relative stroke h (y/L) are known. The inner diameter D (cm) of the water outlet of the valve core shell (3) is D +2 delta, and the delta value can be obtained through experimental measurement or calculation and then experimental verification.

x＝5(d+D)-10(d-(d-0.38858*Q*(0.9*y/L+0.1)*(0.1/(1-0.9*(0.9*y/L+0.1)²))1/2)1/2+δ。
