Abstract
The utility model relates to a top pressing non-leakage water tap, which comprises a valve body, a valve rod, a valve, a water inlet, a water outlet, and a hand wheel. The top pressing non-leakage water tap is characterized in that the internal part of the chamber of the valve rod is provided with a leather cup device which causes one part of the valve rod in the chamber of the valve body to be sealed in the leather cup; the other part and the valve are totally isolated out of the leather cup, and the position of the valve rod (the valve) can be controlled through the hand wheel. The utility model has the advantages of simple structure, good tightness, long service life, convenient maintenance, water source saving, etc.
Description
The utility model relates to a kind of valve, and especially a kind of roof pressure does not have the seepage flow water nozzle.
Valve of a great variety on market, resembling the first-class great majority of the fire hose improves conventional construction, the wearing and tearing that reduce between the parts improve the degree of sealing, yet still have blemish in an otherwise perfect thing, its internal structure complexity, difficulty of processing is big, seal still not ideal enough, particularly at inner body after a period of time is used wearing and tearing, will remove and change part or scrap, this not only brings a lot of troubles to the user, also causes waste.
The purpose of this utility model provides a kind of tightness height, and roof pressure easy to maintenance does not have the seepage flow water nozzle.
The utility model solves by following technical proposal: it mainly is made of valve body, valve rod, valve, water intake, water outlet, handle.Its structural feature is to be provided with the leather cup device in valve cavity, the valve rod some that will be in the valve body is sealed in the leather cup device, another part and the valve that is located at the valve rod bottom are completely cut off outside the leather cup device, leather cup is by fixing with the nut of valve body screw-internal thread fit, handle replaces with handwheel, handwheel matches with the valve body outside thread, and valve stem tip matches with handwheel, and valve is made of pad and seal ring; Also can be by constituting with valve rod bottom all-in-one-piece protuberance and seal ring.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model example structure schematic representation.
As shown in Figure 1, this embodiment mainly is made of valve body 1, valve rod 2, valve 3, water intake 4, water outlet 5, handwheel 6, its structural feature is to be provided with leather cup device 7 in valve body 1 cavity, a part that is in the valve rod 2 in valve body 1 cavity is sealed in the leather cup device, another part and the valve 3 that is located at valve rod 2 lower ends all completely cut off outside leather cup device 7, leather cup device 7 is tightened by the nut 8 with valve body 1 screw-internal thread fit, handwheel 6 matches with valve body 1 outside thread, matches with handwheel in valve rod 2 tops.Valve 3 is by constituting with valve rod 2 bottom all-in-one-piece protuberances 9 and seal ring 10.
In the time will opening, rotation hand wheel 6 makes on it and moves, and at this moment because the pressure of water makes valve 3 be subjected to a power that makes progress, valve 3 and valve rod 2 is moved on together, and valve open water is flowed out by the valve port water outlet.
In the time will closing, rotation hand wheel 6 moves down it, and at this moment valve rod 2 is subjected to the pressure of handwheel, and the pressure that makes valve rod 2 and valve 3 overcome water moves down together, and until valve is sealed, water can not flow out.
Opening and closing in the closed procedure, the seal ring 16 on the valve 3 plays seal action all the time, and when seal ring used when being worn by a period of time, leather cup device 7 still plays good seal action.Adopt this kind structure that the double seal function is arranged, and inner components damage replacing is easily,, again nut 8 is screwed out as long as handwheel 6 is screwed off, just can be the leather cup 7 of inside, valve rod 2, valve 3 taking-ups.
From the above, the utlity model has simple in structure, good airproof performance, long service life, maintenance The advantages such as convenience, saving water source.
Claims (3)
1, a kind of roof pressure does not have the seepage flow water nozzle, comprise valve body, valve rod, valve, water intake, water outlet, handle, it is characterized in that: in valve cavity, be provided with the leather cup device, the part that will be in valve body chamber inner valve stem is sealed in the leather cup device, another part and the valve that is located at the valve rod lower end all completely cut off outside the leather cup device, and leather cup is by fixing with the nut of valve body screw-internal thread fit, and handle replaces with handwheel, handwheel matches with the valve body outside thread, and valve stem tip matches with handwheel.
