Abstract

The equipment belongs to a valve device of a water supply system. Its structure is by the compound water gate at top, middle water pipe, and the intraductal connecting rod of water pipe reaches following valve and constitutes, is equipped with the jam in the valve, is the spring below the valve plug, and the jam is fixed with the connecting rod lower extreme, and the delivery port is equipped with to the valve side, because the reciprocating of valve plug forms and the switch of jam, closes the back surplus water edgewise delivery port and flows, its advantage: simple structure, convenient installation and use, good antifreezing performance and suitability for outdoor installation and use in northern cold weather.

Description

Non-frost plug

The utility model belongs to the valving of water system, is specially adapted to the outdoor water supply in cold weather area and uses.

At present, place at some northern cold weathers, outdoor water valve all adopts up concave type, promptly be that water valve is put into the underground layer that do not freeze, the thick stick method is pressed in the switch utilization of valve, is a brute spring in the middle of the valve, be spool above, utilize lever principle to press spool to make the tap water outflow by bar from ground, the spring ball float is housed on sidewall discharges the surplus water of water pipe, pressure is big when tap water flows out, the side water outlet is closed, surplus water pressure is little after water valve cuts out, and can discharge from the side, guarantees that outlet pipe does not freeze, the control of this kind valve is dumb, water outlet is wayward, must utilize a wooden stick to make crowbar in addition, uses inconvenience.

For solving the deficiency of above valve, the purpose of this utility model provides a kind of Non-frost plug, utilizes the structure of water valve and middle bar and bottom valve on the ground to realize the purpose that winter, outdoor water intaking valve did not freeze.

Structural design of the present utility model is achieved in that this Non-frost plug is by the compound water valve in top, the internal water main pipe, connecting rod and following valve are formed, wherein the compound water valve in top side is for going out water valve, positive for opening and closing water valve, opening and closing water valve middle is switching knob, vertically be connected with connecting rod below the knob, the connecting rod outside is a water pipe, and the obstruction in connecting rod lower end and the valve is fixed, and this valve outside is a body, in the middle of the valve is valve plug moving up and down, be logical ice pipe in the middle of the valve plug, pressure spring be housed below the valve plug, between valve plug outside and the body rubber seal is housed respectively up and down, be obstruction above the valve plug, stop up with top bar lower end and fix, have water outlet in the place corresponding with valve plug, valve body side, body lower end and running water pipe join, in order to prevent the freezing of middle water pipe, be added with thermal insulation layer in the water pipe outside.

Advantage of the present utility model: simple in structure, reasonable in design, easy to install, the parts stable performance, long service life is adapted at the outdoor water intaking in the vast north and uses.

Detailed structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is the Non-frost plug structure principle chart;

Fig. 2 is the decomposition chart of Non-frost plug.

Its structure is by shown in Figure 1, and structure is labeled as: 1. Non-frost plug, 101 thermal insulation layers, 2. water pipe, 201 connecting rods, 202 compound water valves, 3. stop up 4. valve, 401 water service pipes, 402 rubber seal, 403 pressure springs, 5. body is during use, knob rotation with compound water valve, connecting rod rises, and drives simultaneously to stop up to rise, and the current in the water pipe are chewed outflow by water pipe (2) from water by in the water service pipe (401), when the knob backspin, connecting rod drives to stop up and forces valve plug (4) to move down, and makes to stop up and the water intake sealing, and the interior remaining water of water pipe is flowed out from water outlet (501), make pipe interior anhydrous at last, so just prevented that winter, water pipe from freezing crack damaged.

Claims

1. Non-frost plug, it is characterized in that this Non-frost plug top is by compound water valve (201) internal water main pipe (2), connecting rod (201) and following valve (4) are formed, wherein the compound water valve in top side is for going out water valve, positive for opening and closing water valve, opening and closing water valve middle is switching knob, vertically be connected with connecting rod (201) below the knob, the connecting rod outside is water pipe (2), obstruction (3) in connecting rod (201) lower end and the valve (5) is fixing, valve (5) outside is a body, in the middle of the valve (5) is valve plug moving up and down (4), in the middle of the valve plug (4) is water service pipe (401), below the valve plug (4) is pressure spring (403), between valve plug (4) outside and the body rubber seal (402) is housed respectively up and down, is obstruction (3) above the valve plug (4).

2. by the described Non-frost plug of claim 1, it is characterized in that having water outlet (501) with the corresponding place of valve plug (4), be added with thermal insulation layer (101) in the outside of water pipe (2) in valve (5) body side.
