Abstract
The present invention provides a kind of antifreeze ball valve, including valve body, bonnet, heating arrangements；The valve body is fixedly connected with bonnet；On the contact surface of the bonnet and valve body, annular groove is offered, heating arrangements are fixed in annular groove；Pin interfaces are further opened with the bonnet, power line enters in annular groove from pin interfaces to be electrically connected with heating arrangements.The present invention compared with prior art, has the advantages that：By opening up annular groove on bonnet, realization can fix heating arrangements in bonnet, so as to realize to valve body heating and anti-freezing.
Description
Technical field
The present invention relates to valve technology field, a kind of specifically antifreeze ball valve.
Background technology
Ball valve is applied when on water route, for blocking or connecting current.In the winter time, especially northerly winter, temperature
Relatively low, ball valve easily freezes, and causes ball valve normally-open, in addition ball valve valve body by spreading, by bursting by freezing, cause ball valve whole
Body is scrapped.
The content of the invention
The invention aims to solve the defects of lacking in the prior art for ball valve freezing proof technique, there is provided Yi Zhongfang
Freeze ball valve to solve the above problems.
To achieve these goals, technical scheme is as follows：
A kind of antifreeze ball valve, including valve body, bonnet, heating arrangements；The valve body is fixedly connected with bonnet；In the bonnet
With on the contact surface of valve body, offering annular groove, heating arrangements are fixed in annular groove；Lead is further opened with the bonnet to connect
Mouthful, power line enters in annular groove from pin interfaces to be electrically connected with heating arrangements.
Preferably, it is additionally provided with an annular flange on the contact surface of the bonnet and valve body；The annular flange is in ring
Shape groove inner ring；The annular spacing groove to match with annular flange is offered on the contact surface of valve body and bonnet.
Preferably, it is fixed with gasket seal in the annular spacing groove.
Preferably, it is further opened with mounting hole on bonnet and valve body；The mounting hole opens the outer ring in annular groove.
Preferably, the heating arrangements are heating wire.
The present invention compared with prior art, has the advantages that：
By opening up annular groove on bonnet, realization can fix heating arrangements in bonnet, and valve body is heated so as to realize
It is antifreeze.
, both can be quickly integral by valve body and bonnet assembling by the cooperation of flange and stopper slot, water can be extended again
Road, avoid the contact surface of water from valve body and bonnet from oozing out, hence into annular groove, damage heating arrangements.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention；
Embodiment
The effect of to make to architectural feature of the invention and being reached, has a better understanding and awareness, to preferable
Embodiment and accompanying drawing coordinate detailed description, are described as follows：
As shown in figure 1, a kind of antifreeze ball valve, including valve body 1, bonnet 2, heating arrangements 3；Heating arrangements in the present embodiment
3 be heating wire.Valve body 1 is bolted to connection with bonnet 2；On the contact surface of bonnet 2 and valve body 1, annular groove is offered
21, heating arrangements 3 are fixed in annular groove 21；Pin interfaces 22 are further opened with bonnet 2, power line enters from pin interfaces 22
It is electrically connected with annular groove 21 with heating arrangements 3.
Bonnet 2 on the contact surface of valve body 1 with being additionally provided with an annular flange 23；Annular flange 23 is in annular groove 21
Circle；The annular spacing groove 11 to match with annular flange 23 is offered on the contact surface of valve body 1 and bonnet 2.In annular stop
Gasket seal 12 is fixed with groove 11.By the cooperation of flange 23 and stopper slot 11, both quickly valve body 1 and bonnet 2 can be filled
With integral, water route can be extended again, avoid the contact surface of water from valve body 1 and bonnet 2 from oozing out, hence into annular groove 21,
Damage heating arrangements 3.
Mounting hole 4 is further opened with bonnet 2 and valve body 1；Mounting hole 4 is opened in the outer ring of annular groove 21.It is general to start
There are 4 mounting holes 4, be evenly distributed on the surrounding of bonnet 2 and valve body 1.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
For personnel it should be appreciated that the present invention is not limited to the above embodiments, that described in above-described embodiment and specification is the present invention
Principle, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these change and
Improvement is both fallen within the range of claimed invention.The protection domain of application claims by appended claims and its
Equivalent defines.
