Description

Valve device with exhaust function special for water supply

Technical Field

The utility model relates to the field of water supply valve related products, in particular to a valve device with an exhaust function special for water supply.

Background

In water supply equipment, because of the start-stop of the water pump and the switch of the valve that need to be controlled, need to weld a lot of screw threads on water supply equipment pipeline and its jar body for the usage of valve connection sensor or exhaust class comes real-time transmission water supply stability signal to control system, and the timely start-stop of control system water pump and the switch of valve play the protection municipal water supply safety, guarantee resident user water safety.

But too many screw openings are welded on the pipeline, so that the overall appearance of the equipment is influenced and harmony is realized. On one hand, the water leakage phenomenon of the water supply pipeline and the pipeline caused by excessive welding of the tank body is greatly improved in the aspect of later use.

Disclosure of Invention

The utility model aims to provide a valve device with an exhaust function special for water supply, which realizes the functions of exhaust and opening and closing simultaneously through one valve, the two functions are not influenced mutually, the functions of the two valves are realized by means of one valve body, the cost of raw materials is saved, the times of opening holes and welding on a tank body and a pipeline of water supply equipment are reduced, the personnel cost is reduced, the probability of leakage phenomenon in later use caused by welding is reduced, and the problems in the background art are solved.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a special valve gear from taking exhaust function of supplying water, includes the valve body, one side intercommunication of valve body has the blast pipe, be equipped with the valve rod in the valve body, the one end of valve rod runs through valve body and fixedly connected with hand wheel, the one end that the valve rod is located the valve body is connected with the case, be equipped with relative inside spacing seat and the spacing seat in outside that sets up in the blast pipe, inside spacing seat all with blast pipe inner wall fixed connection with the both ends of the spacing seat in outside, be equipped with the hollow floater that density is greater than the air and is less than water between inside spacing seat and the spacing seat in outside, all be equipped with the opening on the both ends lateral wall of inside spacing seat, one side middle-end department of outside spacing seat is equipped with the gas vent.

Preferably, a sensor interface is arranged at the top of the valve body.

Preferably, the valve body is of a hollow cylindrical structure.

Preferably, the valve rod and the valve core are installed through threads.

Compared with the prior art, the utility model has the beneficial effects that:

this supply water special use is from taking exhaust function valve gear, and a valve realizes exhaust and switch function simultaneously, and two kinds of functions do not influence each other, with the help of a valve body, realize that the function of two kinds of valves practices thrift raw and other materials cost, reduce trompil and welding number of times on water supply equipment jar body and pipeline, reduce personnel's cost, reduce because of the welding leads to the probability that the seepage phenomenon appears in the later stage use.

Drawings

FIG. 1 is a schematic structural diagram of a valve device with an exhaust function specially used for water supply according to the present invention;

fig. 2 is a schematic view of the internal structure of a valve device with an exhaust function specially used for water supply of the present invention.

In the figure: 1. a valve body; 2. an exhaust pipe; 3. a valve stem; 4. a hand wheel; 5. a valve core; 6. an inner limiting seat; 7. an external limiting seat; 8. a hollow floating ball; 9. an opening; 10. an exhaust port; 11. a sensor interface.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, an embodiment of the present invention is shown: the utility model provides a water supply is special from taking exhaust function valve device, including valve body 1, one side intercommunication of valve body has blast pipe 2, be equipped with valve rod 3 in the valve body 1, valve body 1 and fixedly connected with hand wheel 4 are run through to the one end of valve rod 3, the one end that valve rod 3 is located valve body 1 is connected with case 5, be equipped with the spacing seat 6 in inside and the spacing seat 7 in outside of relative setting in the blast pipe 2, the both ends of spacing seat 6 in inside and the spacing seat 7 in outside all with 2 inner wall fixed connections of blast pipe, be equipped with the hollow floater 8 that density is greater than the air and is less than water between spacing seat 6 in inside and the spacing seat 7 in outside, all be equipped with opening 9 on the both ends lateral wall of spacing seat 6 in inside, one side middle-end department of spacing seat 7 in outside is equipped with gas vent 10.

Further, the top of the valve body 1 is provided with a sensor interface 11.

Further, the valve body 1 is a hollow cylindrical structure.

Further, the valve rod 3 and the valve core 5 are installed through screw threads.

The working principle is as follows: first when secondary water supply equipment starts in earlier stage because the pipeline is inside to have a large amount of gas, thereby close valve body 1 through rotating hand wheel 4 drive valve rod 3 messenger case 5 is rotatory, gas discharges gas through gas vent 10 on the spacing seat 7 of outside through 6 side opening 9 of inside spacing seat, after secondary water supply equipment tends to stable, thereby it opens valve body 1 to rotate hand wheel 4 drive valve rod 3 messenger case 5 rotation, because valve body 1 is inside to be full of liquid, liquid enters into inside through 6 side opening of inside spacing seat, because water pressure is even around hollow floater 8, extrude hollow floater 8 to the gas vent 10 department of outside spacing seat 7, hollow floater 7 combines completely with gas vent 10, form a confined space, form a complete system with secondary water supply equipment.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
