Abstract
The invention relates to a simple pressure reducing valve which comprises a valve body, valve covers, baffles, a sieve tube and inner and outer O-shaped sealing rings, wherein the valve covers are connected with both ends of the valve body and are sealed by the O-shaped sealing rings; the baffles are fixedly arranged at both ends of an inner cavity of the valve body and are sealed by the outer O-shaped sealing rings; the sieve tube is connected to offset center inner holes of the baffles; vertical small holes are designed in the sieve tube.
Description
Technical field
The present invention relates to a kind of Simple pressure relief valve, especially medium is the Simple pressure relief valves used such as water, oil.
Concrete background technique
Reduction valve is to make medium pass through the valve that this downstream pressure descends by a series of constructional devices, at present, reduction valve classification commonly used is a lot, but the reduction valve in each classification exists complex structure, Heavy Weight, use inconvenience, be difficult for the shortcomings such as carrying, usually give normal next a lot of inconvenience in production or using process.
Summary of the invention
In order to overcome above-mentioned reduction valve deficiency at work, the invention provides a kind of Simple pressure relief valve, this valve mainly is comprised of valve body, valve gap, baffle plate, screen casing, seal ring.This valve not only simple structure, be easy to handling, and weight is light and handy, cost-saving, also has the characteristics such as the simple assembling of technique is quick.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Simple pressure relief valve comprises that valve body, valve gap, baffle plate, screen casing, seal ring form, the valve body two ends are threaded connection two valve gaps, and sealed with " O " RunddichtringO, the other end car of valve gap has screw thread, baffle plate is equipped with at body cavity two, place, baffle plate partial center hole design one endoporus, in hole, screen casing is housed within it, the screen casing the other end is suspended from body cavity, the various apertures of design on screen casing, aperture becomes vertical distribution, between its valve body and baffle plate, adopts " O " RunddichtringO to be sealed.When medium flows into valve body by an end valve lid endoporus, through the baffle plate endoporus, flow in screen casing, under the effect of pressure medium by screen casing on aperture flow into body cavity, also can flow out by screen casing top endoporus, in body cavity flow into the screen casing vertical aperture of the other end connection, and flow in the other end screen casing inner chamber, thereby thereby flow out reduction valve by the other end valve gap endoporus, realize the purpose of decompression.
Effective effect of the present invention: can be in the situation that reduce the purpose that a lot of component are realized decompression, and have its volume little, lightweight, assemble the advantages such as easy for installation, applicable various production environments.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be further described.
Accompanying drawing 1 is structure principle chart of the present invention
In Fig. 1: 1, valve body 2, valve gap; 3, baffle plate 4, screen casing 5, outer " O " RunddichtringO; 6, interior " O " RunddichtringO; 7, external pipe
Embodiment
In accompanying drawing 1, two valve gaps 2 are threaded connection at valve body 1 two ends, the plane contact place is sealed by interior " O " seal ring 6, valve gap 2 is connected with external pipe 7 by outside thread, valve body 1 inner chamber two ends are connected to respectively baffle plate 3, and carry out seal ring with it by outer " O " type sealing 5, and baffle plate 3 places, partial center hole connect screen casing 4, screen casing 4 the other ends are suspended from valve body 1 inner chamber, the purpose by the medium in it in screen casing 4 vertical distribution aperture inflow and outflow actual reduced pressure.
First fill when mounted screen casing and be arranged on baffle plate, baffle plate is put into to body cavity, then two valve gaps are connected to the valve body two ends.
Claims (3)
1. a Simple pressure relief valve, be by valve body, valve gap, baffle plate, screen casing, inner and outer O " RunddichtringO forms, it is characterized in that: valve gap is with being threadedly connected to the valve body two ends, and sealed with " O " RunddichtringO.
2. Simple pressure relief valve according to claim 1, it is characterized in that: baffle plate is fixed on the body cavity two ends, and is sealed with " O " seal ring.
