Pressure management device

A pressure management device 10 for use with a heating system is disclosed which obviates the need for manual topping up of the heating system, protects against flooding and avoids danger of backflow of heating system fluid and consequent contamination of a mains water supply. The pressure management device comprises a one-way valve 16 disposed in the fluid flow path and arranged to permit flow in the direction from the inlet toward the outlet and to resist flow in the opposite direction. A pressure reducing valve 18 is configured to respond to an outlet pressure of the pressure management device, being normally maintained in a closed state by the outlet pressure but adapted to open when the outlet pressure falls below a threshold. In this way the pressure reducing valve causes the heating system to be topped up when necessary. Additionally a flood prevention device 20 is configured to close in response to excessive flow through the pressure management device, so that any risk that the ...

Drinking water heater with venting fitting

The venting fitting (10, figure 1) is installed in a feed pipe (12, figure 1) of a drinking water heater with an air cushion. The fitting has a housing with a housing interior 102 located between a water inlet 36 and outlet 38. The fitting also has at least one air inlet 42 connected to atmosphere and having an air pressure chamber (134, figure 15) defined between an air inlet valve (e.g. backflow preventer 116) and a moveable lifting element (e.g. piston 108). Movement of the element causes a volume and pressure change in the chamber, with the air inlet valve permitting air to enter the chamber from ambient when the chamber pressure falls sufficiently. A one-way air outlet valve (e.g. grooved ring 130, figure 15) permits air to pass from the chamber into the housing interior and mix with water when the air chamber reaches a pre-set pressure. A drive moves the element. The drive may comprise a turbine wheel 74 that turns when there is water flow through the fitting to move the element back ...

A self-bleeding radiator valve (82, fig.4) comprising a filter (100, fig.4) arranged to inhibit particulate matter from interfering with the operation of the valve is disclosed. A filtration device (106, fig.5) for a central heating system, preferably comprising a magnetic particle filter, is also disclosed.

Line-regulating valve

In a line-regulating valve, its housing has an inlet and outlet branch and connecting branches arranged transversely thereto, projecting in a common plane from the same longitudinal side of the housing and intended for a valve top part supporting the closure element, for measuring devices and for a filling and emptying valve, a connecting branch for the reception of a device for measuring the pressure of the medium being arranged downstream of the valve seat. In order to be able, using the inserted measuring device, to measure pressures of the medium corresponding to the actual pressure losses in the valve, the connecting branch (5) intended to receive a pressure-measuring device opens into a channel (13) which is routed around the valve top part (7) and the said channel (13) opens into the passage (12) through the housing on that side of the valve top part (12) which faces away from the abovementioned connecting branch (5) and faces the outlet branch (3). <IMAGE>

Boiler control device and control method

The present invention provides a boiler control device and a control method which more properly controls a conductivity of a boiler water in a boiler drum. According to an embodiment of the present invention, provided is a boiler control device which comprises: a water level gauge; a water supply valve; a blow valve; a first flow meter; a second flow meter; a third flow meter; a conductivity meter; a first control unit; and, a second control unit. The water level gauge measures a water level in the drum. The water supply valve controls a flux of the supplied water. The blow valve controls a flux of blow. The first flow meter measures the flux of the supplied water. The second flow meter measures a flux of steam. The third flow meter measures the flux of blow. The conductivity meter measures the conductivity of the water in the drum. The first control unit controls the water supply valve to make the water level uniform. The second control unit calculates a conductivity after a certain time has passed based on the results of the measurements of the conductivity meter, the second flow meter, and the third flow meter; and controls the blow valve to let conductivity be within a set scope by responding to the results of the calculation.

Method for feeding a closed liquid system

A method for automatically feeding a closed liquid system from a liquid source according to need by creating between the liquid source and the closed liquid system a load buffer formed from liquid, in which between the liquid source and the feed buffer only liquid flow in the direction of the feel buffers is allowed and from the feed buffer to the closed liquid system only drorpwise liquid transport is admitted. The feed buffer can be realized with a cylindrical drip feeder with inlet, outlet and freely movable plunger, which can close the outlet in an abutting position while leaving clear a minuscule leakage channel and is provided with a passage with a non-return valve in the direction of the inlet. Such a drip feeder can, with or without insertion of a storage container for liquid, be connected with, for instance, a liquid system, such as a central heating system with pipe system, boiler and expansion tank.

Drinking water supply connection for water heating system - has valve, pressure reducer and non-return valve to avoid contamination

The arrangement which allows water from a drinking water supply to be used for a water heating system, is designed to prevent contamination of the drinking water and to exclude air from the heating circuit. The water cock(10) hasa part spherical valve plug (26) which rotates about a horizontal axis, and the hole (28) through it is vertical in the closure position. This cock also has an opening (46) underneath, which communicates with the plus opening (28) in the closure position. Under this opening is a holder connected to a drainage line. Between the cock and the heating apparatus is a pressure reducer (58) which has a return flow blocking device (108) at its outlet to the heating system.
