Abstract

The utility model relates to a novel electric valve which is composed of a valve body and a valve rod arranged in the valve body, wherein a combining cup and a press cup which is matched with the combining cup is arranged outside the valve rod; in the combining cup, a plurality of V-shaped shims, a flat shim, a spring and an O-shaped ring are sequentially arranged below the press cap, and the combining part of the combining cup and the valve body is also provided with an O-shaped ring. The lower end of the valve rod is provided with a valve core, and the valve core is fixed by an elastic washer and a nut; the valve core is rigidly sealed with a valve core combining cup, the other end of the valve rod is provided with a regulating cup and the regulating cup is fixed by a socket head screw. The bottom part of the valve body is also provided with a sealing cover, and the sealing cover is sealed with the bottom part of the valve body by an O-shaped ring. The utility model is suitable for the opening and the closing control of central air-conditioning systems, heating systems, water treatment systems, industrial processing systems, etc.

Description

Electric valve valve

Technical field

The utility model relates to a kind of electric valve valve.

Background technique

Raising along with Chinese economic development and people's quality of life, be applied to the fluid control member of systems such as central air-conditioner, heating, water treatment, industrial processes industry, the application of valve more and more widely, and require more and more higher, environmental protection, energy-conservation, be theme efficiently.And China is small-sized to produce at present, and technology content is not high, and based on manual poor efficiency valve, automatic, efficient electric valve is few.And compare with external like product, exist bigger gap on technology and quality, the working efficiency, therefore, the higher cost that spares no expense mostly is from external import.

Summary of the invention

The purpose of this utility model is at the existing shortcoming of above-mentioned valve, and a kind of electric valve valve reasonable in design is provided.

In order to achieve the above object, the utility model has mainly adopted following technological scheme to realize.The utility model mainly is made up of valve body and the valve rod be located in the valve body, outside valve rod, be provided with and cap and the pressure cap that is mated, and cap in, below pressure cap, be provided with some V-arrangement pads, flat gasket, spring and O shape circle successively, and cap also is provided with O shape with the valve body connecting part and encloses.The spool of establishing in the lower end of valve rod, spool is fixed by elastic washer and nut, spool and spool and the cap rigid seal be located in the valve body, the other end of valve rod is provided with the adjusting cap, is located by socket head screw.Bottom at valve body also is provided with stifle, and by seal with O ring.

The utility model compared with prior art has following obvious advantage and progress.(1) use split-type structural, valve and driver can be installed separately, and be easy to loading and unloading.(2) four layers of V-arrangement teflin ring are adopted in sealing on the valve rod, add a pressure spring, compress seal ring all the time, the effectively compensation sealing circle wearing and tearing that repeatedly move up and down and cause by valve rod, and the external leakage that can guarantee this one fully is zero.(3) accurately selection, the key component material of valve is stainless steel or brass, not only anti-corrosive properties are good, and will not influence the sealability of valve because of corrosion.Owing to adopt metal hard-sealing, temperature tolerance also improves greatly than the valve that adopts rubber or plastic seal, and also can prolong working life.(4) be provided with stifle in the bottom of valve body, stifle is the reservation parts of the utility model when being used for threeway, in case change stifle, just can transform threeway into and use.

The utility model is applicable to the fluid ON/OFF control of systems such as central air-conditioner, heating, water treatment, industrial processes.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The description of drawings book

Accompanying drawing is the utility model overall structure cut-away view.

Embodiment

As shown in the figure, the utility model mainly is made up of valve body 14 and the valve rods 5 be located in the valve body 14, outside valve rod 5, be provided with and cap 10 and the pressure cap 2 that is mated, and cap 10 in, below pressure cap 2, be provided with some V-arrangement pads 3, flat gasket 11, spring 12 and O shape circle 13 successively, and cap 10 also is provided with O shape circle 4 with valve body 14 connecting parts.The spool of establishing in the lower end of valve rod 5 15, spool 15 is fixing by elastic washer 7 and nut 16, and spool 15 and spool and cap 6 rigid seals be located in the valve body 14, the other end of valve rod 5 are provided with regulates cap 1, fixing by socket head screw 9.Bottom at valve body 14 also is provided with stifle 8, and by 17 sealings of O shape circle.

The utility model is applicable to the fluid ON/OFF control of systems such as central air-conditioner, heating, water treatment, industrial processes.
