Abstract
The utility model relates to a sealing ring replaceable valve. A sealing ring is arranged in a valve body; a pressing sleeve is arranged between the sealing ring and a valve cover; filling material is respectively arranged between the sealing ring and the pressing sleeve and between the pressing sleeve and the valve cover. When the sealing ring is damaged in use, the valve cover only needs to be opened, the pressing sleeve is taken out, and a new sealing ring is replaced; because the sealing ring can be replaced for many times, the service life of the value is prolonged; the utility model has the advantages of unique structure, simple manufacture, convenient operation, good tightness, etc.; the utility model is a novel valve with strong practicability and great popularization value.
Description
The utility model relates to a kind of valve, specifically is a kind of seal ring replaceable valve.
Existing valve generally all belongs to disposable use, because of the sealing surface of valve all is to fix on valve body with built-up welding or drive fit mode, so, must remove and scrap whole valve in case the valve sealing surface damages institute causes revealing, both increase cost of production, caused certain waste again.
The purpose of this utility model solves above existing in prior technology problem with regard to being, and a kind of structure uniqueness that provides, be easy to make, easy to operate, good seal performance and conveniently replaced novel valve.
Technical solution of the present utility model is to realize like this.The seal ring replaceable valve, comprise the valve rod that is contained in the valve body, the valve gap that is contained in the flap of stem bottom and is located at valve body top, it is characterized in that seal ring is located in the valve body, be provided with gland between seal ring and the valve gap, be provided with filler between seal ring and the gland, be provided with filler between gland and the valve gap.
Described seal ring is provided with outside thread, and valve body is provided with internal thread, and seal ring and valve body are provided with pad by being threaded between valve body and the seal ring.
Described filler can also be a pad.
Below in conjunction with accompanying drawing the utility model valve is further described.
Fig. 1 is the utility model valve mechanism schematic representation.
Fig. 2 is another structural representation of the utility model valve.
As described in Figure 1, the utility model seal ring replaceable valve, comprise valve gap 1, valve body 2, flap 3, filler 4, seal ring 5, valve rod 6, filler 7, gland 8, valve rod 6 is located in the valve body 2, the bottom of valve rod 6 is provided with flap 3, valve gap 1 is located at the top of valve body 2, seal ring 5 is located in the valve body 2, be provided with gland 8 between seal ring 5 and the valve gap 1, valve gap 1 is pressed on gland 8 in the valve body 2, in order to reach good sealing effect, between seal ring 5 and gland 8, filler 4 is set, between gland 8 and valve gap 1, filler 7 is set.
When seal ring 5 in use damages, only need valve gap 1 is opened, take out gland 8, seal ring 5 is taken out, change Xinmi City's seal and get final product.
Fig. 2 is another embodiment of the utility model seal ring replaceable valve.On seal ring 5 outside thread is set, on the valve body 2 internal thread is set, seal ring 5 and valve body 2 are provided with pad 9 by being threaded between valve body 2 and the seal ring 5, can guarantee sealing effect.When needing to change Xinmi City's seal, only need that seal ring 5 is screwed off replacing from valve body 2 and get final product.
Compared with prior art, the characteristics of the utility model maximum are that sealing ring can repeatedly be changed, thereby make Greatly prolong the service life of valve, so both saved production cost, reduced again loss, has knot The structure uniqueness, be easy to make, the advantage such as easy to operate, good seal performance, be a kind of practical, have The novel valve of promotional value.
