Abstract
The utility model provides a calorifier for motor train units. The calorifier comprises a housing, a water storage inner container arranged in the housing, and an electric heating tube arranged in the water storage inner container, wherein, the bottom of the water storage inner container is communicated with a water drainage pipe, the upper part thereof is communicated with a hot water pipe, and the lower part thereof is communicated with a cold water pipe; the cold water pipe is communicated with a water inlet pipe; a reducing valve is arranged on the water inlet pipe; the hot water pipe and the water drainage pipe are communicated through a swelling water outlet pipe; and a pressure-limiting valve is arranged on the swelling water outlet pipe. The utility model has the advantages of high water pressure resistance and fast water heating rate.
Description
Technical field
The utility model relates to technical field of water heaters, a kind of specifically EMUs water heater.
Background technology
Existing passenger train forces down, goes out with water heater is water-fast that hot water is slow, power is big.Existing water heater inner bag is a box-structure, resistance to pressure is bad and inner no measures to reduce stresses.Existing water heater adopted the hot type mode of heating, promptly by flow switch control, did not heat during no flow, just heated when flow is arranged, because electrothermal tube has a temperature-rise period, when opening depotition cock, the water of outflow will heat up gradually like this, so it is slow to go out hot water.Simultaneously, cross the hot type mode of heating and can not heat stored hot water in advance, therefore must have bigger power could satisfy instructions for use.
The utility model content
The purpose of this utility model is for providing a kind of water pressure resistance height, removing the fast EMUs water heater of hot water.
The technical scheme that realizes the foregoing invention purpose is as follows:
The EMUs water heater comprises shell, is located at the water storage liner in the shell, is provided with electrothermal tube in the water storage liner; The bottom of described water storage liner is communicated with a drainpipe, top is communicated with hot-water line, the bottom is communicated with cold water pipe, described cold water pipe is communicated with a water inlet pipe, described water inlet pipe is provided with pressure-reducing valve, be communicated with by a swelling water outlet pipe between described hot-water line and the drainpipe, described swelling water removes water pipe and is provided with pressure limiting valve.
Described water storage liner is the cylindrical shape stainless steel inner container.
The utility model can satisfy the pressure oscillation scope of intake pressure 0.1-0.6Mpa, and can make discharge pressure not influenced by intake pressure by increasing pressure-reducing valve.Water heater is designed to the storage-type mode of heating, can utilize free time that cold water is heated to design temperature and insulation, can go out hot water immediately in use.Simultaneously, the heating power of water heater can significantly reduce, and is about about 30% of existing water heater.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the EMUs water heater comprises shell, is located at the water storage liner in the shell, is provided with electrothermal tube in the water storage liner; The bottom of described water storage liner is communicated with a drainpipe, top is communicated with hot-water line, the bottom is communicated with cold water pipe, described cold water pipe is communicated with a water inlet pipe, described water inlet pipe is provided with pressure-reducing valve, be communicated with by a swelling water outlet pipe between described hot-water line and the drainpipe, described swelling water outlet pipe is provided with pressure limiting valve.Hot-water line of the present utility model is used to hot water, and the water that will add thermal expansion by the swelling water outlet pipe is discharged to drainpipe simultaneously.Cold water pipe on the one hand by water inlet pipe retaining in the water storage liner, directly provides cold water to the outside on the other hand.
Described water storage liner is the cylindrical shape stainless steel inner container.Have withstand voltage height, lightweight characteristics.
Accompanying drawing of the present utility model and explanation focus on improvement part, for other structure in the prior art, with due other configurations of water heater, do not provide, but do not represent the utility model not have relevant structure or configuration, just be clearly outstanding improved technical scheme of the present utility model.
