Abstract

The utility model relates to a special valve assembly for a water heater, which is composed of a gate valve 1, different-diameter tees 2 which are positioned at both ends of the gate valve, and small rotary plugs 3 which are connected with the different-diameter tees. The utility model is utilized for connecting the water heater for use. The original water pipe can be utilized fully. Other water pipes do not need to be arranged through the wall. The cold and the hot water can be conveniently used whether at a kitchen or a toilet.

Description

Special valve component for water heater

The utility model relates to a kind of novel water heater special valve sub-assembly, belongs to the family expenses plumbing.

At present gas heater is installed by family, generally adopts following two kinds of methods: the one, and Inlet and outlet water all uses plastic flexible pipe, and this installation method is easier, but uses after one, two year the plastic flexible pipe will ageing hardening, and has peculiar smell in the pipe, needs regular update; Two are to use running water pipe to install, and this method is more bothersome.More than two kinds of methods all must through walls burrowing, if also will use hot water every the Room or kitchen between kitchen and the toilet, will arrange more water pipe during installation, this to a certain degree also can influence the attractive in appearance of room.

The purpose of this utility model can rationally be utilized original water pipe for people provide a kind of exactly, does not need through walls burrowing when water heater is installed, and the hot and cold water of drainpipe, and use in addition is water heater special valve sub-assembly easily.

For achieving the above object, the utility model has designed a special-shaped gate valve, and these gate valve body two ends respectively have a circular hole, respectively inserts a pet cock again in the hole, promptly constitutes water heater valve assembly described in the utility model.

Be common gate valve for the ease of in actual production, adopt standard component and reduce the production difficulty, special-shaped gate valve can be disassembled as far as possible, special-shaped t-bend two parts, two special-shaped t-bends are positioned at the gate valve two ends, and its junction is lined with the sealing spacer, implements promptly to adopt this scheme.

The utility model is simple in structure, easy for installation, can utilize original water pipe rationally and effectively, does not need through walls burrowing, and drainpipe can keep original environment in room in addition.And it is little to solve water use peak use in the summer water heater water yield.High this problem of temperature; And, no matter in the kitchen or in the toilet, can both use hot and cold water easily.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a schematic appearance of the present utility model.

Fig. 2 is the schematic diagram of the utility model reducer tee.

Fig. 3 is the schematic diagram of the utility model pet cock structure.

Fig. 4 is that the utility model is installed and used example schematic.

As shown in Figure 1, the utility model is made of a common gate valve 1, two reducer tees 2 and two pet cocks 3.Reducer tee 2 two ends are respectively external screw thread and internal thread (as shown in Figure 2), and its male end connects with gate valve 1 two ends respectively, and intermediate cryptographic envelope spacer 4 compresses; Its female end then become the two ends of this water heater valve assembly and pet cock and common tap structure that reducer tee 2 joins basic identical, constitute (as shown in Figure 3) by faucet valve 5, spool 6, gland 7, O RunddichtringO 8, spring 9, handle 10, screw 11 etc.Pet cock 3 valve bodies and gate valve 1 valve body are perpendicular.Its handle 10 is in same orientation with gate valve handwheel 12.

During use, the utility model is installed between the house water meter outlet and first bleeder (as shown in Figure 4), water heater and pet cock of the present utility model 3 is linked by joint and pressure hose.When using running water at ordinary times, only need close two pet cocks 3, gate valve 1 gets final product in the middle of opening.When using water heater, then gate valve 1 is closed, open two pet cocks 3, refire water heater duration and degree of heating kept burning day and night, at this moment open any one water consumption device on the pipeline (tap, the seedpod of the lotus first-class), water heater master duration and degree of heating all can be lighted, and water consumption device goes out hot water.

In summer during water use peak, hydraulic pressure is low, and the water yield is little.At this moment use the water heater temperature generally all higher.Address this problem, only need open some gate valves 1, allow hot and cold water enter pipeline simultaneously, the water yield just will obviously increase, and water temperature is descended.

Claims

1, a kind of water heater special valve sub-assembly is made of special-shaped gate valve and pet cock, it is characterized in that respectively having a circular hole on the special-shaped gate valve body two ends, and this hole links to each other with pet cock.

2, water heater special valve sub-assembly as claimed in claim 1 is characterized in that special-shaped gate valve is made of common gate valve, special-shaped t-bend, and two special-shaped t-bends are positioned at the gate valve two ends, and its junction is lined with the sealing spacer.
