Abstract
The present invention discloses a balance type valve of an electric valve, which is composed of a valve body, a valve cover arranged above the valve body, and a valve rod arranged in the valve body, wherein an O-shaped ring is arranged between the valve cover and the valve body for sealing, and a doubling cap and a press cap are arranged on the valve cover. A plurality of layers of U-shaped shims, flat shims and springs are orderly arranged below the press cap, and an O-shaped ring is arranged between the doubling cap and the valve cover. The lower end of the valve rod is provided with a valve core which is fixed on the valve rod by a nut. A spring ring and a sealing ring are arranged above the valve core for sealing, and a pressure plate is arranged above the spring ring and the sealing ring. The pressure plate is fixed on the valve core by a bolt and a spring shim, and a through hole is also arranged on the valve core. The through hole is communicated with a chamber arranged at the upper part of the valve body, and the valve core and the valve body form rigid sealing. The present invention is suitable for starting / stopping control of central air-conditioning systems, heating systems, water treatment systems, industrial processing systems, etc.
Description
Technical field
The present invention relates to a kind of valve of electric valve, especially relate to a kind of balance type valve of electric 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.Our above-mentioned valve of using always at present, when opening or closing, spool all will be subjected to the impact force of pipeline inner fluid to it, the impulse force of valve fluid when opening or closing will be transmitted on the valve rod by spool like this, very easily to product go up sealing or other auxiliary produces destructive impact, and back pressure is arranged when opening or closing.
Summary of the invention
The objective of the invention is to shortcoming, a kind of balance type valve of electric valve is provided at above-mentioned valve existence.
In order to achieve the above object, the present invention has adopted following technological scheme to realize.The present invention is provided with seal with O ring mainly by valve body and be located at the valve gap of valve body top and valve rod located therein is formed between valve gap and the valve body, and valve gap is provided with also cap and pressure cap, is provided with several layers U-shaped pad, flat gasket and spring below pressure cap successively.And be provided with O shape circle between cap and the valve gap.The lower end of valve rod is provided with spool, spool is fixed on the valve rod by nut, the spool top is provided with spring ring and seal ring sealing, spring ring and seal ring top are provided with pressing plate, pressing plate is fixed on the spool by the bolt and spring washer sheet, also be provided with through hole on spool, through hole communicates with the cavity volume of being located at valve body top, and spool and valve body are rigid seal.
The present invention compared with prior art has following obvious advantage and innovation.(1) at spool through hole is set, make spool when body cavity slides up and down, fluid will be full of this cavity volume by this through hole, fluid just can be distributed in the positive and negative both sides of spool like this, so when switch valve, can reduce fluid greatly to the valve impact forces, the back pressure active force of spool is almost nil simultaneously, reach pressure balanced purpose, the valve of this point and other form is very different.(2) adopt multilayer U-shaped teflin ring on the valve rod, add a pressure spring, compress seal ring all the time, effectively the compensation sealing circle is because the wearing and tearing that valve rod repeatedly moves up and down and causes, the external leakage that can guarantee this one fully is zero.(3) stainless steel spring circle and teflin ring sealing are adopted in spool top, and adopt the bottom and the structure of valve body rigid seal, fully guaranteed sealability of the present invention, and temperature tolerance also improves longer service life greatly than the valve of similar employing rubber or plastic seal.(4) the present invention adopts split-type structural, and valve and driver can be installed separately, and be easy to loading and unloading.(5) key component of the present invention adopts high-quality stainless steel or brass, and not only anticorrosive property is good, and will not influence the sealability of valve because of corrosion.
The present invention is applicable to the 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 present invention is described in further detail.
Description of drawings
Accompanying drawing is an overall structure cut-away view of the present invention.
Embodiment
As shown in the figure, the present invention is mainly by valve body 15 and be located at the valve gap 18 of valve body 15 tops and valve rod 8 located therein is formed, be provided with 9 sealings of O shape circle between valve gap 18 and the valve body 15, valve gap 18 is provided with and cap 4 and pressure cap 2, is provided with several layers U-shaped pad 3, flat gasket 5 and spring 7 below pressure cap 2 successively.And be provided with O shape circle 6 between cap 4 and the valve gap 18.The lower end of valve rod 8 is provided with spool 16, spool 16 is fixed on the valve rod 8 by nut 14, spool 16 tops are provided with stainless steel spring circle 12 and teflin ring 13 sealings, stainless steel spring circle 12 and teflin ring 13 tops are provided with pressing plate 17, pressing plate 17 is fixed on the spool 16 by bolt 10 and compression spring 11, also be provided with through hole 19 on spool 16, through hole 19 communicates with the cavity volume 20 of being located at valve body 15 tops, and spool 16 is a rigid seal with valve body 15.
The present invention is applicable to the ON/OFF control of systems such as central air-conditioner, heating, water treatment, industrial processes.
