Abstract
The utility model provides an antifreeze purge ball valve used for an fire engine, which comprises a valve body wall and a ball valve inner cavity, and the antifreeze purge ball valve is characterized in that: the valve body wall is an internal hollow interlayer-typed structure, a resistance wire is wound in the interlayer, the access end of the resistance wire protrudes out of the valve body wall, and the valve body wall is provided with a wind inlet communicated with the ball valve inner cavity. The utility model is applicable to the field of water supply and drainage, the antifreeze of the ball valve is achieved by the combination of the heating and blowing mode, the device further improves the utilization efficiency of the ball valve, especially on the application of fire engines, and the work efficiency is further improved.
Description
Technical field: the utility model relates to the antifreeze purging ball valve of a kind of valve, particularly a kind of used in fire-fighting.
Background technique: at present, ball valve has been widely applied the plumbing field, especially need a large amount of ball valves to control fire-fighting water on the fire-fighting truck, and common ball valve, at inner icing, have a strong impact on water with regard to being easy to be frozen in the winter time, reduced the efficient of work, even the cool air in winter can be freezing with ball valve, and how to overcome the above problems is a problem that demand side is right.
Summary of the invention:
Goal of the invention: the utility model provides a kind of used in fire-fighting antifreeze purging ball valve, its objective is the problem that influenced water even be damaged by frost when ordinary ball valve runs into cool air in the past that solved, especially at fire-fighting domain, further solve ordinary ball valve influences fire-fighting efficient at arctic weather problem.
Technological scheme: the utility model is achieved through the following technical solutions:
The antifreeze purging ball valve of a kind of used in fire-fighting comprises valve body wall and ball valve inner chamber, and it is characterized in that: valve body wall is the sandwich type structure of inner hollow, is wound with resistance wire in the interlayer, and stretch out outside the valve body wall access termination of resistance wire; Valve body wall is provided with intake grill and communicates with the ball valve inner chamber.
Advantage and effect: the utility model provides a kind of used in fire-fighting antifreeze purging ball valve, it is designed to valve body wall the sandwich structure of hollow, and the direction along valve body wall is wound with resistance wire in interlayer, by power supply is whole ball valve heating, in arctic weather, for the fire-fighting truck through the outdoor work of being everlasting, this device is very effective, before using and use back power-on is its heating, can guarantee the proper functioning of ball valve; In addition, valve body wall is provided with intake grill and communicates with the ball valve inner chamber, and intake grill in use is connected with the gas receiver of fire-fighting truck, after the fire-fighting truck operation finishes, blow in cavity by gas receiver, remaining water in the cavity is blown out, it is icing to prevent that remaining water from remaining in the cavity; This antifreeze ball valve is realized the antifreeze of ball valve by the mode of the combination of heating and wind, and this device has further improved the utilization ratio of ball valve, especially is applied on the fire-fighting truck, has further improved working efficiency.
Description of drawings:
Fig. 1 is a broken section structural representation of the present utility model;
Fig. 2 is a side structure schematic representation of the present utility model.
Embodiment: the utility model is done nearly step explanation below in conjunction with accompanying drawing:
As shown in Figure 1, the antifreeze purging ball valve of a kind of used in fire-fighting, the valve body wall 1 of this antifreeze purging ball valve is the sandwich type structure of inner hollow, is wound with resistance wire 2 in the interlayer, resistance wire 2 twines along the radial direction of valve body wall 1; Stretch out outside the valve body wall 1 the access termination of resistance wire 2, and the incoming end of resistance wire 2 in use inserts automobile storage battery, provides the power supply of heating by automobile storage battery for it; Valve body wall 1 is provided with intake grill 3 and communicates with ball valve inner chamber 4, this intake grill 3 is communicated with gas receiver on being arranged on fire-fighting truck by pneumatic tube, provide source of the gas to reach the purpose of purging by gas receiver for it, the form of gas receiver and specification can be selected as required.
The antifreeze purging ball valve of this used in fire-fighting in use, ball valve is opened, ball valve is started working, at this moment, the control ball in the ball valve inner chamber 4 is just in time with intake grill 3 sealings, and water can not flow out from intake grill 3, and behind end-of-job, especially in the air of outdoor cold, the antifreeze effect of this moment is especially obvious, at this moment, close ball valve, the opening surface of the control ball in the ball valve inner chamber 4 at this moment, is opened the gas receiver switch towards intake grill 3, air communication is crossed in the intake grill 3 input ball valve inner chambers 4, the remaining large-area water at each position in the ball valve inner chamber 4 is blown out,, make resistance wire 2 begin heating by automobile storage battery then to prevent that residual water from forming larger area and freezing, utilize air-flow and the mode that adds thermal, make remaining a spot of water flash evaporation in the ball valve inner chamber 4, guarantee the drying in the ball valve inner chamber 4, prevent to freeze; And before using next time, for preventing to also have the ice quarrel in the ball valve inner chamber 4, then power-on makes resistance wire 2 work, and the ice-out with remaining a spot of water that may exist in the ball valve inner chamber 4 is tied further guarantees normal working efficiency.
This antifreeze purging ball valve is realized the antifreeze of ball valve by the mode of the combination of heating and wind, and this device has further improved the utilization ratio of ball valve, especially is applied on the fire-fighting truck, has further improved working efficiency.
