Abstract
The utility model relates to a valve leak preventer comprising a bottom-holder frame and a spring, wherein one end of the spring is connected with the bottom-holder frame, and the other end thereof is connected with a pressing end for pressing towards the sealing direction of the valve. The leak preventer has good leak preventive effect, simple structure and hard damage.
Description
Technical field
The present invention relates to the particularly leak-proof device of inclined to one side switch operating rod ceramics valve of a kind of valve.
Background technique
Switch operating rod ceramics valve is not the airtight degree of tightening ceramics when cutting out partially, and just be screwed onto airtight angle, valve seal pressure leaks easily than a hour valve when variation in pressure is big, the key position of a lot of Stainless Steel Valve copper valves-the operating stem screw is the screw that can become rusty partially, can't the dismounting and change parts when find leaking, even replaceable cost is also higher.
Summary of the invention
The objective of the invention is at above-mentioned condition, a kind of leak preventer of valve is provided.
Technological scheme of the present invention is: a kind of leak preventer of valve, and the backing frame connects an end of spring, and the other end of spring is a live end, and spring can be arc, and spring can be a plurality of.Useful stainless steel is made.The backing frame can be not occluded ellipse shape, holds protuberance at the bottom of the valve, and live end stresses on the inclined to one side operating stem groove of tightening up a screw, and can adjust spring force as required.
The invention has the beneficial effects as follows: because leak preventer of valve is over against the sealing pressuring direction, so good leak-proof effect is and simple in structure, not fragile.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the leak preventer of valve of proposition according to the present invention.
Embodiment
Below, embodiments of the present invention are described with reference to the accompanying drawings.
Partially switch operating rod ceramics valve 7 is connected with water pipe 1, and the end connection backing frame 5 of a plurality of semielliptic springs 2,3 pairs of inclined to one side operating stem of the other end live end of the semielliptic spring groove 4 of tightening up a screw pressurizes, and inclined to one side operating stem 6 is arranged, floss hole 8.
Claims (3)
1. a leak preventer of valve is characterized in that the backing frame connects an end of spring, and the other end of spring is the end of exerting pressure.
2. according to the described leak preventer of valve of claim 1, it is characterized in that spring is arc.
3. according to claim 1 or 2 described leak preventer of valve, it is characterized in that spring is a plurality of.
