Abstract
The invention provides a pressure-resistant heating and ventilation valve. The pressure-resistant heating and ventilation valve comprises a valve body and a controller arranged on the valve body, an adjusting knob is arranged between the valve body and the controller, a valve element is arranged inside the valve body, and the pressure-resistant heating and ventilation valve is characterized in that the valve body is cylindrical, a throttling orifice is arranged on the valve element, the flow passage area is adjusted through throttling orifices in the throttling orifice plate, and a pressure gauge is arranged at the water outlet of the valve body. The valve body is arranged to be cylindrical, the front and back inner diameters are kept uniform, and therefore the overall size of the valve is easily reduced; the flow passage area of the throttling orifice plate is adjustable so that the throttling orifice plate can be adapted to front and back changes of the valve, and the purpose of controlling flow can be achieved; the pressure gauge is used for monitoring fluid pressure in real time, so that the front and back pressure difference is conveniently controlled. Dynamic balance of a heating and ventilation system is easily controlled, and the pressure-resistant heating and ventilation valve is convenient to install in a narrow space and suitable for application and popularization.
Description
Technical field
The invention belongs to valve technology field, particularly relate to a kind of HVAC valve.
Background technique
Along with the high speed development of Chinese national economy, the building construction scale in city is increasing, and the requirement of people to indoor environment is also more and more higher.Using and running of the HVAC systems such as how especially some large-scale commercial buildings, improve effective commercial area ratio, guarantee air-conditioning does not increase energy consumption therefrom, is the problem that heating and ventilating discipline is paid close attention to.Due to the restriction of condition in present air conditioner heating engineering, often unequal pipe road system is adopted in actual use, unequal pipe road system pipeline is long, the resistance difference of end-equipment is large, large in the available pressure head surplus near cold & heat source position, often there is assignment of traffic off-design state, cause system hydraulic misadjustment.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the withstand voltage HVAC valve that a kind of flow control is stablized, waterpower adjustment balances, installation simplifies.
For achieving the above object, the technical solution used in the present invention is:
A kind of withstand voltage HVAC valve, comprise valve body and be arranged on the controller on valve body, adjusting knob is provided with between valve body and controller, spool is provided with in valve body, it is characterized in that described valve body is cylindrical shape, described spool is provided with restricting orifice, and described restricting orifice is by the adjusted flow area of throttle orifice on it, and valve body water outlet is provided with pressure gauge.
The cross section of described restricting orifice is circular.
Described restricting orifice surrounding is provided with seal ring, and seal ring and valve inner fit tightly.
Described throttle orifice is the circular hole that diameter is identical.
Beneficial effect of the present invention is: valve body is arranged to cylindrical shape, and front and back internal diameter is consistent, and is conducive to reducing valve overall volume; Restricting orifice area of passage is adjustable, adapts to the change before and after valve, reaches the object controlling flow; The real-time monitoring fluid pressure of pressure gauge, is convenient to control front and back pressure reduction.The present invention is conducive to the transient equiliblium controlling HVAC system, and is convenient to be arranged in narrow space, is suitable for applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of restricting orifice of the present invention.
In figure: 1-valve body, 2-controller, 3-adjusting knob, 4-restricting orifice, 5-throttle orifice, 6-pressure gauge, 7-spool, 8-seal ring.
Embodiment
For understanding content of the present invention, Characteristic further, hereby exemplifying following examples and being described with reference to the accompanying drawings as follows:
A kind of withstand voltage HVAC valve, the controller 2 comprising valve body 1 and be arranged on valve body 1, be provided with adjusting knob 3 between valve body 1 and controller 2, valve body 1 is cylindrical shape, and spool 7 is provided with restricting orifice 4, restricting orifice 4 is by the adjusted flow area of throttle orifice 5 on it, valve body 1 water outlet is provided with pressure gauge 6, and the cross section of restricting orifice 4 is circular, and restricting orifice 4 surrounding is provided with seal ring 8, seal ring 8 and valve body 1 inner tight are fitted, and throttle orifice 5 is the circular hole that diameter is identical.
Working procedure of the present invention is: fluid flows through the restricting orifice 4 on spool 7, through the shunting action of throttle orifice 5, and water flow spaces balance and stability, flow can not produce wide fluctuations; The pressure condition of convection cell can be monitored by valve body 1 water outlet pressure gauge 6, be convenient to control flow equilibrium.
Above the specific embodiment of the present invention has been described in detail, but described content being only better embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
