Description
Technical field
The utility model relates to liquid carrying valve field.
Background technique
Manually-operated gate is controlling component in pipeline fluid transporting system, and it is used to change path section and media flow direction, has the functions such as water conservancy diversion, cut-off, adjustment, throttling, non-return, shunting or overflow release.For the valve that fluid controls, the inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m to latus rectum from atomic little Gauge Valves.Valve can under the effect of pressure, temperature or other form transducing signal, by pre-provisioning request action, or do not rely on transducing signal and simply open or close, valve rely on drive or automechanism makes open-shut device be elevated, slippage, swing or rotation motion, thus the size changing its Flow area is to realize its controlling functions.Traditional manually operated valve comprises valve body, valve rod, and threaded stem is connected in valve body, and valve rod bottoms liquid passage place is provided with spool, and by rotary valve rod, the position of spool is changed, and the size of regulates liquid passage, realizes the adjustment of fluid flow.In the production process of chemical reagent, strictly must control the amount of adding material, to the adjustment of valve body, there is high-precision requirement, but what current manually operated valve valve rod employing was common is threaded in valve body, screw thread in Long-Time Service process due to wearing and tearing, coordinate and become lax, had a strong impact on the degree of regulation of valve body.
Model utility content
The utility model is intended to provide a kind of degree of regulation high, the spiral valve body of chemical reagent static pressure of long service life.
The spiral valve body of chemical reagent static pressure in this programme, comprise valve seat, valve rod, spool, described valve seat is provided with water intake and water outlet, water intake and water outlet are separated by spool, and described spool is connected to the lower end of valve rod, and valve rod is located in valve seat, described valve rod and valve seat adopt and are threaded, valve seat and valve rod are respectively equipped with thread, the bi-side of the thread on valve seat all have oilhole, described oilhole is connected with the oil transportation road be located on valve seat; The thread top of valve seat has oilhole, and this oilhole is connected with oil expulsion channel.
Beneficial effect: by rotary valve rod, makes valve rod move down, and allows the joint of spool shutoff entery and delivery port of valve rod bottom, realizes turning down of fluid flow; The program be provided with oilhole, oil transportation road and oil expulsion channel in the threaded connection place of valve seat, because the thread of the thread of valve seat and valve seat is separated by the oil film that the pressure oil that oil supply system provides is formed, what namely adopt is static pressure spiral, not wearing and tearing between thread, and working life is elongated; Simultaneously oil film can also absorbing and eliminate gap, compensates the manufacturing tolerances between valve seat and valve rod, makes power screw precision high, thus the degree of regulation of valve seat is uprised.The spiral valve seat of chemical reagent static pressure that the program provides, long service life, durable, degree of regulation is high, is applicable on the chemical production equipment that needs strictly to control chemical raw material adding quantity.
Further, the oilhole on the side that the thread on described valve seat parallels adopts same oil transportation road to be communicated with, and two oil transportation roads corresponding to the side in both direction are connected, and unidirectional thread side adopts same oil transportation road, and pressure oil is evenly distributed.
Further, the upper end of described valve rod is provided with rotating disk, more laborsaving, improves the simple operation of adjustment process.
Further, between described valve rod and valve seat, sliding parts is provided with Sealing, prevents the leakage of chemical liquid.
Further, the material of described Sealing is asbestos, and a lot of chemical reagent is with acid, alkali or corrosivity, adopts the Sealing of asbestos material that chemical solution can be prevented the corrosion of Sealing, makes it lose seal action.
Accompanying drawing explanation
Fig. 1 is the structural representation of the spiral valve body embodiment of the utility model chemical reagent static pressure;
Fig. 2 is the structural representation in A portion in this Fig. 1.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference character in Figure of description comprises: valve seat 1, water intake 11, water outlet 12, oil transportation road 13, oil expulsion channel 14, valve rod 2, spool 21, rotating disk 22, floor 3.
Embodiment is substantially as shown in accompanying drawing 1, Fig. 2: the spiral valve body of this chemical reagent static pressure, comprise valve seat 1, valve rod 2, spool 21, valve seat 1 has water intake 11 and the water outlet 12 of arc inner wall, water intake 11 and water outlet 12 are separated by spool 21, spool 21 is welded on the lower end at valve rod 2, be socketed in valve seat 1 below valve rod 2, thread is processed with respectively above valve seat 1 He above valve rod 2, the bi-side of the thread on valve seat 1 all have oilhole, and oilhole is connected with oil transfer pump by oil transportation road 13; The thread top of valve seat 1 has oilhole, and this oilhole is connected with oil expulsion channel 14, towards fuel tank.
Valve seat 1 has two oil transportation roads 13, oilhole on the side that thread on valve seat 1 parallels is communicated with same oil transportation road 13, and two oil ducts are connected, and lead to oil transfer pump, unidirectional thread side adopts same oil transportation channel, and pressure oil is evenly distributed.The upper end of valve rod 2 is provided with rotating disk 22, more laborsaving, improves the simple operation of adjustment process.The Sealing that between valve rod 2 and valve seat 1, sliding parts asbestos are made, prevent the leakage of chemical liquid, a lot of chemical reagent is with acid, alkali or corrosivity, adopts the Sealing of asbestos material that chemical solution can be prevented the corrosion of Sealing, makes it lose seal action.Be welded with floor 3 at the water intake 11 of valve seat 1 and the outer wall place of water outlet, make valve seat more firm.
Rotate rotating disk 22 valve rod 2, move down while valve rod 2 is rotated, allow the spool 21 shutoff water intake 11 of valve rod 2 bottom and the connection mouth of water outlet 12, realize turning down of fluid flow; Counterrotating, then tune up fluid flow.The program has oilhole, oil transportation road 13 and oil expulsion channel 14 in the threaded connection place of valve seat 1, the thread of valve seat and the thread of valve seat 1 are separated by the oil film that the pressure oil that oil supply system provides is formed, what namely adopt is static pressure spiral, and almost do not have anything to wear and tear between thread, working life is elongated; Simultaneously oil film can also absorbing and eliminate gap, compensates the manufacturing tolerances between valve seat 1 and valve rod 2, makes power screw precision high, thus the degree of regulation of valve seat is uprised.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
