Abstract
The utility model relates to an aerosol spray valve, which provides a spray valve which is used on single-component polyurethane foam calking agent glossy jar, which comprises a hollow valve bar, a valve bottom, an inner sealing ring which is made of elastic material and a valve base which is provided with a center hole. One end of the valve bar is provided with a small hole, the valve bottom is fixed on the end portion on one end of the valve bar which is provided with the small hole. The inner sealing ring comprises a ring base and a cylindrical ring body which is connected in a whole with the ring base, the connector of the ring base and the ring body is provided with a groove, the ring base and one end of the valve bar which is provided with the small hole are provided with flow passages, the lower portion of the ring base is pressed on the upper portion of the valve bottom, the valve bar is inserted in the inner sealing ring, the groove is tightly matched with a center hole, the inner sealing ring is fixed on the valve base, and the diameters of the contacting portions between the valve bottom and the ring base are the same. The utility model has simple structure, which has bigger practical valve, which can avoid the small parts of feed liquid which is accumulated and water which gets into from gaps reacting to generate glue to adhere a valve. The utility model is convenient for popularization and application.
Description
Technical field
The utility model relates to a kind of aerosol spray valve.
Background technology
Polyurethane foam (English name PU foam) since the phase at the beginning of the seventies in last century as a kind of marvellous chemical test byproduct, developed for a long time so far.And sealing agent of single component polyurethane foam has purposes very widely owing to carry with easy to use in numerous industries, has developed into one of most important product of polyurethane industry at present.
Said polyurethane foam performed polymer, can are in the aerosol jar, and the aerosol tank top is provided with the aerosol spray valve, and aerosol valve is to influence the key technology that product uses, and directly influences serviceability.Aerosol valve must reliably make aerosol content ejection go effectively, excellent sealing performance is arranged in off position the time again, makes that aerosol content is non-leakage to come out.
But, be used in the aerosol valve on the one-component polyurethane foam aerosol jar at present, structure is not too reasonable, the polyurethane foam prepolymer is with after valve contacts, the part prepolymer remains in valve rod and inner seal ring place, and micro-moisture that infiltrates from the slit from air and prepolymer reaction form foam, and two parts are bonded together, cause valve not open, had a strong impact on the use of product.
Summary of the invention
The purpose of this utility model provides a kind of spray valve that is used on the sealing agent of single component polyurethane foam aerosol jar, to overcome the above-mentioned defective that prior art exists.
The spray valve that is used on the sealing agent of single component polyurethane foam aerosol jar of the present utility model, comprise the valve rod, valve of hollow at the bottom of, the inner seal ring made of elastomeric material and the valve seat that is provided with centre bore;
One end of said valve rod is provided with aperture, be fixed on the end of an end that is provided with aperture of valve rod at the bottom of the said valve, said inner seal ring comprises ring support and is linked to be columned circle body for one with ring support, ring support is provided with groove with the junction of circle body, the end place that ring support and valve rod are provided with aperture is provided with runner, the bottom of ring support is against the top at the bottom of the valve, said valve rod is inserted in the inner seal ring, said groove and said centre bore closely cooperate, said inner seal ring is fixed on the valve seat, it is characterized in that the diameter with the ring support contact position at the bottom of the said valve is identical.
Because the diameter at the bottom of the valve is identical with the diameter of ring support, therefore, can buildup between diameter at the bottom of the valve and the ring support, thus can avoid because the reaction of moisture generation glue of coming in the small part feed liquid of accumulation and the slit clings valve.
By above-mentioned disclosed technical scheme as seen, the utility model structure is very simple, has bigger practical value, and is easy to utilize.
