Description

Temperature measurement locking valve is adjusted to two sides that can accurate control flow

Technical Field

The utility model relates to a hot-water heating valve body field, concretely relates to temperature measurement locking valve is adjusted to two sides that can accurate control flow.

Background

The valve is a control part in a fluid conveying system, has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting, overflowing and relieving pressure and the like, and is implemented by different types of valves. Valves used in fluid control systems range in variety and size from the simplest shut-off valves to the variety of valves used in extremely complex autonomous systems. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valves are further classified into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves, etc. according to the material.

In a heating system, heat distribution is an important parameter index, and a heating company can reasonably distribute heat according to the requirement of a user or the demand of the user on the heat, so that energy can be effectively saved, a mode of supplying more heat in places with more heat and supplying less heat in places with less heat can be realized, and the heat distribution are not influenced; for example, in recent years, building heating systems are all in individual heating mode, namely, in order to reasonably distribute heat, and in order to reduce energy waste, not only the new floors are in the mode, but also old communities and countries are greatly invested in individual heating, and the transformation strength is already covered in three-four-line or below cities or counties, and the transformation coverage range almost covers all regions of the country.

The initial heating mode is combined heating, radiators of all residents are connected in series, the implementation disadvantage is that some users live in middle houses of floors, and some are side houses, so that the indoor temperature of the middle houses is higher than that of the side houses in winter correspondingly, in order to ensure the temperature of the side houses, the heating load can be increased, the indoor temperature of the users of the middle houses is too high, people have to open windows to cool, the heat waste is undoubtedly caused, and due to the series connection, the single-house regulation cannot be realized, and the heat circulation of the whole building can be influenced by the single-house regulation; the heat waste is not much for a single household, but for the whole heating company, the effect of a plurality of cells supplied at the same time is very obvious, and the waste is undoubtedly huge; and the waste is unacceptable for energy reasons.

After the household heating mode is adopted, heat is reasonably distributed, so that the accurate adjustment of the household liquid flow is the most effective and the most direct means, the household flow is slow in circulation, the temperature is naturally not too high, and the household flow is fast in circulation, so that the temperature is naturally and obviously improved.

According to investigation, many users do not want to adjust small flow for cooling even if the indoor temperature far meets the required heat, and the adopted means is generally windowing for cooling and even opening an air conditioner for cooling, so that the meaning of individual heating is not too large, and the optimal mode is that a heating company carries out uniform distribution management, and the uniform distribution scheduling of the heating company needs to achieve accurate temperature control (if each layer of a corridor is provided with a heating well), and if the indoor optimal temperature in winter is 23-25 ℃; with this kind of mode, current flow control valve can't satisfy the user demand, specifically as follows:

the first and the different households have different heating quantities, heating modes and heating areas in the households, which results in different indoor actual temperatures of the households under the same flow rate, so that the actual temperature of each household is most suitable, visual adjustment is needed, the current adjusting valve body cannot obtain the indoor temperature of the household after adjustment (adjustment and control are carried out in a heating well in a corridor), if the adjusting flow rate is too large, reasonable distribution cannot be achieved, if the adjusting flow rate is too small, household complaints can be caused, and obviously, the implementation is difficult to promote; therefore, although the existing heating can be adjusted by each household, the heating is generally implemented in a mode of fully opening the flow, and the fine adjustment and control cannot be achieved.

Secondly, the current regulation and control cannot be precisely controlled, only can be roughly regulated and controlled, although the rough regulation and control can be implemented, the fine management is still challenging and difficult, and the fine distribution heat required by a heating company cannot meet the requirement.

Thirdly, as the master control of each household is in the heating well of the corridor, and the valve body cannot be locked, a leak exists, namely all people who can open the heating well can regulate and control the heating well, but according to the management regulation, the regulation and control and the operation of the heating equipment can only be implemented by the personnel authorized by the heating company or the heating company, otherwise, once the heating equipment has a problem, the responsibility cannot be divided; the existing market also has a locking valve with a locking function, but each valve body is required to be provided with a lock cylinder (the structural clearance in the lock cylinder is relatively precise), so that the cost of a single valve body is increased, generally no one in a heating well manages, dust is accumulated more and air is not circulated, dust and moist air permeate into the lock cylinder after a long time, the lock cylinder is blocked, and the problem of regulation failure is also generated.

Fourth, the hot-water heating pipeline in the heating well is generally close to the wall for saving space (and when operating the valve body, just can only operate in the unilateral), so the installation of valve body, just need divide left side dress and adorn again, therefore heating company selects the valve body in the installation, needs select according to the overall arrangement of hot-water heating pipeline, this when implementing, brings some inconveniences for actual installation work, the unhandy of valve body dress, can bring a lot of problems to maintenance, the adjustment in later stage.

Based on the problems, the development of a novel valve body which has excellent comprehensive performance and a structure completely different from that of the conventional regulating valve is very necessary, particularly provides a powerful technical guarantee for the fine management of a heating company aiming at the conventional household heating, and has important significance for enriching the types of the valve body.
