Abstract

A bevel-angle one-way valve mainly solves the problems that a common one-way valve is small in passing flow quantity, easy to block and complex in open pressure adjustment. The bevel-angle one-way valve comprises a valve body which is provided with a transverse in-out channel, a cavity which is oblique upwards and communicated with the transverse channel is arranged in the middle of the channel, a valve cover is in threaded connection with the inside of the cavity, a rubber pad, a pressing ring and a clamping sleeve are sequentially connected under the cavity, a valve core is arranged between the upper end face of the pressing ring and the valve cover, a cylindrical rod on the upper portion of the valve core stretches into a hole under the valve cover, a spring is mounted between the valve core and the valve cover, the clamping sleeve is connected with the pressing ring in an interference fit mode, the clamping sleeve is connected with the valve body in a transition fit mode, and a sealing ring for sealing is arranged between the valve cover and the valve body. By means of the bevel-angle one-way valve, the problem that a liquid channel is narrower due to installation of the valve core is avoided, liquid flow is guaranteed, and meanwhile, the liquid channel is not easy to block, one-way valve open pressure can be adjusted conveniently, and the bevel-angle one-way valve has the advantages of being large in flow and not easy to block, and open pressure can be adjusted easily.

Description

A kind of oblique angle one-way valve

Technical field

The utility model relates to a kind of valve in chemical process field, is specifically related to a kind of oblique angle one-way valve.

Background technique

Common spring one-way valve is generally at the coaxial annular sealing surface that is provided with of valve inner, producing thrust by the valve core spring compression seals liquid in one direction, flow in another direction, generally adjust mobile cracking pressure with the compression degree of adjusting spring, the assemblies such as the spool of coaxial-type spring non-return valve, spring are installed in valve inner, the overcurrent fluid flow is restricted, foreign material in liquid are deposited on the interior assembly of valve body, affect valve working, when adjusting the spring-compressed degree, also need valve is disassembled, waste time and energy.

Summary of the invention

Little in order to solve common coaxial springs formula one-way valve inflow-rate of water turbine, easily stop up, adjust the loaded down with trivial details problem of cracking pressure, the utility model provides a kind of oblique angle one-way valve, this oblique angle one-way valve changes valve body structure, spool is installed at place, valve body oblique angle, thereby solved the problems referred to above, and simple in structure, reliable operation.

the technical solution of the utility model is: a kind of oblique angle one-way valve comprises valve body, valve body has a horizontal import and export passage, a cavity obliquely that communicates with crosspassage is arranged in the middle of passage, the cavity internal thread connects valve gap, be connected with rubber pad below cavity in turn, hold-down ring and cutting ferrule, be connected with spool between hold-down ring upper-end surface and valve gap, the cylindrical bar on spool top stretches into the hole below valve gap, between spool and valve gap, spring is installed, cutting ferrule is connected with the hold-down ring interference fit, cutting ferrule is connected with the valve body transition fit, the seal ring sealing is arranged between valve gap and valve body.

Described a kind of oblique angle one-way valve, spool lower end have the taper anchor ring, hold diameter less than the hold-down ring diameter of bore in face of tapered collar.

Described a kind of oblique angle one-way valve, spool and valve body crosspassage form an oblique angle a who makes progress, and the angle at oblique angle is 55 °.

The utlity model has following beneficial effect: the oblique angle of the spool of this oblique angle one-way valve and fluid passage is installed, avoided because the problem that spool narrows down fluid passage is installed, guaranteed the discharge value of liquid, also made fluid passage be difficult for stopping up simultaneously, oblique installation spool, need not to dismantle valve body, screw thread by rotary valve cover is capable of regulating one-way valve cracking pressure, in sum, the utlity model has flow large, be difficult for stopping up, adjust cracking pressure and be easy to characteristics.

Description of drawings:

Accompanying drawing 1 is structural representation of the present utility model.

In figure 1, valve body; 2, rubber pad; 3, hold-down ring; 4, spool; 5, valve gap; 6, seal ring; 7, spring; 8, cutting ferrule.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

by shown in Figure 1, this oblique angle one-way valve comprises valve body 1, valve body 1 has a horizontal import and export passage, a cavity obliquely that communicates with crosspassage is arranged in the middle of passage, the cavity internal thread connects valve gap 5, be connected with rubber pad 2 below cavity in turn, hold-down ring 3 and cutting ferrule 8, be connected with spool 4 between hold-down ring 3 upper-end surfaces and valve gap 5, the cylindrical bar on spool 4 tops stretches into the hole below valve gap 5, between spool 4 and valve gap 5, spring 7 is installed, cutting ferrule 8 is connected with hold-down ring 3 interference fit, cutting ferrule 8 is connected with valve body 1 transition fit, seal ring 6 sealings are arranged between valve gap 5 and valve body 1.

Described a kind of oblique angle one-way valve, spool 4 lower ends have the taper anchor ring, hold diameter less than hold-down ring 3 diameter of bores in face of tapered collar.

Described a kind of oblique angle one-way valve, spool 4 forms an oblique angle a who makes progress with valve body 1 crosspassage, and the angle at oblique angle is 55 °.
