Abstract
The utility model provides a multifunctional balance valve for system detection and diagnosis and belongs to the technical field of valves. Pressure measuring nozzles are respectively arranged on the walls of a water inlet pipe and a water outlet pipe of a valve body, and a valve cover or the valve body arranged between two pressure measuring nozzles and located on one side of a valve core is provided with a temperature and pressure measuring nozzle. In addition, a lock can be further arranged on a valve rod, and a blow-down branch and a blow-down valve are installed on the valve body. An existing balance valve is only provided with two measuring points, a blocked intermediate filter influences the measurement accuracy of the measuring points to difference of pressures in front and back of the valve, and the problem that actual flows and measured flow data distort is caused. The measuring points for temperature and pressure measurement are added, a thermometer between two original measuring points can be replaced, the measuring points can be combined with the original measuring points in use to measure the difference of pressures in front and back and obtain flows, judgment of the water temperature and pressure and the filth blockage situation in a cavity is facilitated, and meanwhile the influence of filter filth blockage on the measurement is further solved through a third measuring point. The lock is added, so that the multifunctional balance valve has locking and closing functions. The blow-down valve is added, so that blow-down under the pressure can be achieved.
Description
Technical field
The utility model belongs to valve technology field, and particularly a kind of system detects diagnosis Multifunctional balance valve.
Background technique
HVAC industry hydraulic equilibrium and the special-purpose equilibrium valve ubiquity of heat metering following two problems both at home and abroad at present: the one, at water outlet, there is no thermometric, pressure measuring function, and the 2nd, do not possess reliable locking functions and closing function in danger.On market, the locking closure of existing locking equilibrium valve is all mechanical type locking and stuck effect, and performance is not difficult for behaviour entirely to be done, and easily by layman, is destroyed its locked position.
Secondly, in the equilibrium valve of registering one's residence, existing equilibrium valve does not have filtrating equipment, easily causes the circulation of pipe network dirt, affects heating quality.
Summary of the invention
The utility model, for the deficiency of existing product, provides a kind of system to detect diagnosis Multifunctional balance valve.
The technique effect that the utility model adopts is:
On the water inlet tube wall of valve body and water outlet tube wall, pressure measurement mouth is set respectively, it is characterized in that, in the centre of two pressure measurement mouths, on the valve gap of spool one side or on valve body, thermometric, pressure measurement mouth are set.
The upper end of described spool arranges lock.
Described lock is the fixedly lock of being furnished with key, or is furnished with the rotating adjusting lock of locking closure.
Described adjusting is locked dial is set.
On described valve body, blow-off line is set, and on blow-off line, Blowoff ball valve is set.
The beneficial effects of the utility model are:
(1) existing equilibrium valve only has two measuring points, and intermediate filter generation stolen goods are stifled, affects the precision of two measuring points to differential pressure measurement before and after valve, and can cause the data on flows problem of dtmf distortion DTMF of actual flow and measurement.The utility model has increased the general measuring point of thermometric pressure measurement, in the middle of original two measuring points, can substitute thermometer, and with original two measuring point couplings, before and after measuring valve, pressure reduction obtains outflow, be conducive to judge in practice its water-exit temperature and the dirty stifled situation in pressure and cavity, the stolen goods that while the 3rd measuring point has also solved filter block up surveying quantitative limitation.
(2) increase lock, there is locking and locking functions.
(3) increased blowdown valve, having Blowoff ball valve to be connected on can blowdown with pressure on filter.

Embodiment
A kind of system that provides the utility model detects diagnosis Multifunctional balance valve, below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1
As shown in Figure 1, valve body 1 is throughway valve, and spool 3 is arranged on the central position of valve body 1, and its upper surface and valve rod 2 are affixed, and lower surface and valve core head 4 are affixed.Valve rod 2 stretches out valve body 1, and is connected and fixed by valve gap 5 and valve body 1.On the water inlet tube wall of valve body 1 and water outlet tube wall, 1 pressure measurement mouth 6 is set respectively, on valve gap 5, a thermometric, pressure measurement mouth 7 are set perpendicular to valve rod 2.Thermometric, pressure measurement mouth 7 and original two pressure measurement mouth 6 couplings, measure valve front and back pressure reduction and obtain outflow, is conducive to judge in practice its water-exit temperature and the dirty stifled situation in pressure and cavity
Handwheel 8 is installed on the top of valve rod 2, and between handwheel 8 and valve gap 5, the lock 9 of being furnished with key 10 is set.Lock 9 can be by handwheel 8 lockings.
Embodiment 2
As shown in Figure 2, the present embodiment and embodiment's 1 difference is, the direction of thermometric, pressure measurement mouth 7 is vertical setting with valve rod 2.
Embodiment 3
As shown in Figure 3, on valve body 1, blowoff line is set, and Blowoff ball valve 14 is set on blowoff line.In the present embodiment, pressure measurement mouth is vertical with valve body sectional view, does not indicate in the drawings.Thermometric, pressure measurement mouth 7 are arranged near the valve body wall of valve rod 2 sides, between two pressure measurement mouths.The magnetic that install with locking closure 12 at the top of valve rod 2 regulates lock 11, and regulates on lock 11 dial 13 is set in magnetic.Magnetic regulates the adjustment disk of lock 11 detachable, can effectively prevent that lock body is destroyed or arbitrarily regulate.
