Abstract
The utility model discloses a pressure reducing valve for a water supply system, which comprises a casing provided with a water inlet and a water outlet, wherein the water inlet part of the casing is provided with a silica gel sealing pad, a water inlet side of the silica gel sealing pad is provided with a small spring, the other side of the silica gel sealing pad corresponding to the small spring is provided with a rigid support capable of moving to and fro, the top end of the rigid support is connected with the silica gel sealing pad, and the bottom end of the rigid support is provided with a big spring. The pressure reducing valve can effectively overcome the harm caused by a water hammer, the quality reliability and the durability of the pressure reducing valve are improved, water supply pipe networks of tap water and water consumption equipment are protected, and the influence on other water consumption equipment caused by the damage of pipe network equipment is avoided.
Description
Technical field
The utility model relates to a kind of water system reduction valve, particularly a kind of reduction valve that adopts the silica gel material as Sealing.
Background technique
Along with quickening of urbanization process is saved the soil, floor increases gradually, this has just brought inconvenience to town water supply undoubtedly, this just needs to use the secondary water-supply of raw water service pump group, yet the raw water service pump group is being opened and is being stopped, be accompanied by the opening and closing of valve ... the capital produces water hammer in tap water, water hammer may be greater than several times of pressure of supply water, tens times, even tens times, so the consequence that this phenomenon causes can be very serious, therefore the decompressor that adopts in pipeline is very necessary; Decompressor not only has effect of easing stress, and pressure stabilization function is arranged.At present, the decompressor of most of tap water, the cooperation of its internal structure and auxiliary can reduce hydraulic pressure and prevent that water hammer is to parts damages such as water pipe (principle of reduction valve just repeats no more).Key is the quality for the assurance reduction valve, and a little once manufacturers are in order to pursue high profit, and the material of choosing is the effect that can reach decompression in the short time; And in a single day the pipeline pressure regulating equipment of tap water goes wrong, and its consequence is hardly imaginable.
The model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind of reduction valve that adopts the silica gel sealing pad, improves the reliability and the durability of reduction valve, guaranteed the Security of water supply network and watering equipment.
In order to solve above technical problem, the utility model provides a kind of water system reduction valve, comprise the housing that is provided with intake-outlet, be provided with the silica gel sealing pad in described housing water inlet, influent side at described silica gel sealing pad is provided with little spring, be provided with the rigid support that can move back and forth at the opposite side relative with described little spring, described rigid support top links to each other with described silica gel sealing pad, and its bottom is provided with big spring.
The technological scheme that the utility model further limits is: aforesaid water system reduction valve, described little spring, sealing gasket, rigid support and big spring are located on the same line.
The beneficial effects of the utility model are: the utility model is by adopting the silica gel sealing pad; effectively overcome the harm that causes because of water hammer; improve the reliability and the durability of reduction valve quality; protected tap water supply pipe network and watering equipment, stopped to bring disaster to other watering equipments because of the damage of pipe network equipment.
Description of drawings
Fig. 1 is the utility model joint schematic representation.
Embodiment
A kind of water system reduction valve that present embodiment provides, structure as shown in Figure 1, comprise the housing 1 that is provided with intake-outlet, 2 places are provided with silica gel sealing pad 3 at described housing water intake, influent side at described silica gel sealing pad 3 is provided with little spring 4, be provided with the rigid support 5 that can move back and forth at the opposite side relative with described little spring 4, described rigid support 5 tops link to each other with described silica gel sealing pad 3, and its bottom is provided with big spring 6; Described little spring 4, sealing gasket 3, rigid support 5 and big spring position 6 are on same straight line.
Silica gel sealing pad 3 cooperates with big spring 6 threes that are arranged at opposite side with the little spring 4 of reduction valve water inlet, be adjusted to setting pressure after the assembling, although may having significantly, the pressure of water intake changes, because the effect of big little spring 4 is arranged, silica gel sealing rubber cushion 3 pliabilities are strong, the silica gel sealing rubber cushion 3 that makes the water intake little spring control when intake pressure increases overcomes the elastic force of big spring 6 and pushes ahead, the control mouth is reduced, rate of discharge is reduced, thereby kept the pressure that water outlet is set.When very big always pressure reduced suddenly, under the effect of big spring, silica gel sealing rubber cushion 3 is postponed made control mouthful increase so, and the flow velocity of water is accelerated, and keeps the discharge pressure of setting in the same old way, just can play the purpose of decompression and voltage stabilizing.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. water system reduction valve, comprise the housing that is provided with intake-outlet, it is characterized in that: be provided with the silica gel sealing pad in described housing water inlet, influent side at described silica gel sealing pad is provided with little spring, be provided with the rigid support that can move back and forth at the opposite side relative with described little spring, described rigid support top links to each other with described silica gel sealing pad, and its bottom is provided with big spring.
2. water system reduction valve according to claim 1 is characterized in that: described little spring, sealing gasket, rigid support and big spring are located on the same line.
