Abstract
The utility model provides a water cut ultra-high pressure check valve which comprises a valve body and a left and a right join bodies, wherein, the left and the right join bodies are respectively screwed and connected to the left and the right ends of the valve body, an inner hole which is communicated with the left and the right join bodies is arranged on the middle position of the inside of the valve body, the lower part of the valve body is provided with an interface which is communicated with the inner hole, and a pressure transport opening and a water inlet which are arranged on the left and the right join bodies are respectively communicated with the inner hole. The utility model solves the defects of the prior art that the dynamic and static contact area of the valve cores of the existing check valves is small, and the valve cores are easy to destroy. The utility model is one item of technique which is worth popularization.
Description
The utility model relates to metal processing and facility field, specifically a kind of water cutting ultrahigh pressure one-way valve.
At present, the high pressure one-way valve that is used for metal is carried out of a great variety, the different modeling of water cutting in mechanical industry, regardless of its form of expression, it mostly is the spool of taper, aciculiform, spherical structure, little, the flimsy shortcoming of its ubiquity sound area of contact, it can not adapt in the high-pressure water diced system uses.
The purpose of this utility model is for solving above-mentioned technical deficiency part, big, the non-damageable water cutting of a kind of spool sound area of contact ultrahigh pressure one-way valve is provided, and it can adapt to uses in the high-pressure water diced system.
The purpose of this utility model is achieved through the following technical solutions: water cutting ultrahigh pressure one-way valve, it has valve body and left and right fittings body, the left and right two ends of valve body have the left and right fittings body that is threaded mutually with it respectively, the endoporus that neutral position in the valve body communicates with left and right fittings body, the interface that communicates with endoporus is arranged at the bottom of valve body, and the defeated pressure mouth on the left and right fittings body, water intake communicate with endoporus respectively.
Advantage of the present utility model: one, design science is reasonable, and it adopts the spool and the valve seat orifice edge phase plane contact form of plane type, and its sound area of contact is increased, and strengthens greatly so adapt to the ultrahigh pressure ability, and is not fragile; Two, simple in structure, easy manufacturing, with low cost, easy to use and reliable.The utility model is widely used in mechanical industry can produce good social, economic benefit.
Figure of description 1 is a structural representation of the present utility model;
Figure of description 2 is A-A or the B-B view of Fig. 1.
In conjunction with the embodiments the utility model is described in further detail below with reference to Figure of description.
Water cutting ultrahigh pressure one-way valve of the present utility model, it has valve body 19 and left and right fittings body 2,15, the left and right two ends of valve body 19 have respectively and its left and right fittings body that is threaded mutually 2,15, the endoporus 18 that neutral position in the valve body 19 communicates with left and right fittings body 2,15, the interface 17 that communicates with endoporus 18 is arranged at the bottom of valve body 19, and defeated pressure mouthful 1 water intake 16 on the left and right fittings body 2,15 communicates with endoporus 18 respectively.The defeated mouth 1 of pressing is arranged on the fittings body 2 of a left side, be separately installed with bipyramid pad 3, setting sleeve 6 and the valve seat 8 that has the hole respectively in the fittings body 2 of a left side, correspond to each other between its each hole and communicate, be separately installed with spool 7 in setting sleeve 6 holes and have the spring seat 4 in hole, the spring 5 that is installed in the spring seat 4 contacts with spool 7 one ends, spool 7 is slidingly fitted with setting sleeve 6, the other end of spool 7 contacts with the edge, hole of valve seat 8, the two ends, hole of bipyramid pad 3 press mouthful 1 and corresponding the communicating in hole of spring seat 4, the hole of valve seat 8 and endoporus 18 corresponding communicating with defeated respectively.Water-supplying mouth 16 is arranged on the right connector body 15, be separately installed with the bipyramid pad 9, setting sleeve 12 and the valve seat 14 that have the hole respectively in the right connector body 15, correspond to each other between its each hole and communicate, be separately installed with spool 13 in setting sleeve 12 holes and have the spring seat 10 in hole, the spring 11 that is installed in the spring seat 10 contacts with spool 13 1 ends, spool 13 is slidingly fitted with setting sleeve 12, the other end of spool 13 contacts with the edge, hole of valve seat 14, the two ends, hole of bipyramid pad 9 respectively with corresponding the communicating in hole of endoporus 18 and spring seat 10, hole water intake 16 correspondences of valve seat 14 communicate.The cross section of spool 7,13 is respectively square, and its two line intersections are arc.
During manufacturing, will process the assembling of various component by above-mentioned requirements after, screw left fittings body 2, make bipyramid pad 3 in it, valve seat 8 press mouthful 1 and the closely contact mutually of endoporus 18 edges with defeated respectively; Screw right connector body 15, bipyramid pad 9, valve seat 14 in it are closely contacted mutually with endoporus 18 and water intake 16 edges respectively.During use, water intake of the present utility model 16 and raw water service pump are joined, will fail and press mouthful 1 to join, after interface 17 and pressurized machine are joined, water cutting head and accumulator are joined to carry out water cutting work again with accumulator.During working state, with the pressurized machine that interface 17 communicates, during its descent of piston, be negative pressure state in the right connector body 15, spool 13 is moved to the left the hole of opening valve seat 14, and this moment, raw water service pump passed through the surrounding of water intake 16 and spool 13 along injecting in the pressurized machine cylinder body with the water of certain pressure; When the piston in the pressurized machine capable when the lower dead center backhaul, then the water in it is increased to high-pressure water, this moment, spool 13 moved to right under the effect of high-pressure water and spring 11, promptly close the hole of valve seat 14, under the effect of this high-pressure water, overcome simultaneously the active force of left fittings body 2 inner springs 5, promote spool 7 and be moved to the left the hole of opening valve seat 8, high-pressure water then enters accumulator by the surrounding of spool 7 along reaching the defeated mouth 1 of pressing like this, operates the water cutting head that joins with accumulator this moment and can carry out cutting work.Whole motion process of the present utility model is gone round and begun again.Raw water service pump, pressurized machine, accumulator and the water cutting head that uses that match with the utility model is prior art, just do not give unnecessary details one by one here.
