Abstract
The utility model provides an eccentric regulating valve which comprises a valve body, a valve seat and the like. A valve core is located in the valve body and respectively connected with a base shaft and a valve rod, the valve rod penetrates through the valve body, and the base shaft is connected with the bottom of the valve body. The eccentric regulating valve is characterized by further comprising a valve seat stopping ring and wear-resisting layers, the valve core is an eccentric spherical crown, the valve seat is fixedly connected with an inner lateral wall of the valve body through the valve seat stopping ring, a lateral side of the valve seat is fitted with the valve core, the wear-resisting layers are arranged on contact faces of the valve core and the valve seat respectively, and the wear-resisting layers are arranged on surfaces of the valve core and the valve seat respectively. The valve core and the valve seat adopt eccentric structures, abrasion of the valve seat is reduced, and service life is prolonged. The wear-resisting layers are arranged on the contact faces of the valve core and the valve seat respectively and made of Stellite alloy, wear-resisting capability and anti-corrosion capability are strong, service life is prolonged, and leakage possibility is reduced.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of deflection modulating valve.
Background technique
Modulating valve is in the industrial automation process control field, removes to change the final control unit of process parameters such as rate-of flow, pressure, temperature, liquid level by power operation.In use, the spool and the valve seat of modulating valve constantly rub, and one long the appearance easily of time weares and teares, and causes leaking in the modulating valve appearance influence use.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of eccentric regulating valve, comprise valve body, valve seat, spool, lower shaft, valve rod, spool is positioned at valve body and is connected with valve rod with lower shaft respectively, valve rod runs through valve body, lower shaft is connected with the valve body bottom, it is characterized in that also comprising valve seat back-up ring and wearing layer, described spool is eccentric spherical crown, valve seat is fixedlyed connected with described valve body madial wall by the valve seat back-up ring, its side and described spool are fitted, and are respectively arranged with wearing layer on the surface of contact of described spool and described valve seat, and wearing layer lays respectively at described spool and described valve base surface.
The material of described wearing layer is the Si Tailite alloy.
The beneficial effects of the utility model are: spool, valve seat adopt eccentric structure, have reduced the prooving of valve seat, have prolonged working life; Add wearing layer on spool, the contact surface of valve seat respectively, wearing layer adopts the Si Tailite alloy, and is wear-resistant, corrosion resistance is strong, has prolonged working life, reduced to produce the possibility of revealing; Use valve seat back-up ring regulating valve seat, can guarantee that valve seat contacts with the tight of spool, can effectively cut off medium during complete shut-down, improve control accuracy of the present utility model.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Among the figure, 1, valve body; 2, valve seat; 3, spool; 4, lower shaft; 5, valve rod; 6, valve seat back-up ring; 7, wearing layer.
As shown in Figure 1, spool 3 is positioned at valve body 1 and is connected with valve rod 5 with lower shaft 4 respectively, valve rod 5 runs through valve body 1, lower shaft 4 is connected with valve body 1 bottom, and spool 3 is eccentric spherical crown, and valve seat 2 is connected with valve body 1 madial wall by valve seat back-up ring 6, its side and spool 3 are fitted, be respectively equipped with wearing layer 7 on the surface of contact of spool 3 and valve seat 2, wearing layer 7 lays respectively at spool 3 and valve seat 2 surfaces, and the material of wearing layer 7 is the Si Tailite alloy.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
