Abstract

The utility model provides a self-pressing and non leakage adjustable cone disc valve, which is sealed without leakage and can adjust the flow freely and fix the flow adjusting by a pressure closed valve of the system. The utility model can be applied widely in the water, oil, gas and vapor conditions, and is a novel valve after a gate valve, a butterfly valve and a ball valve, and is particularly suitable for controlling the large flow in the pipe. With the compact structure, low cost and stable performance, the utility mode has good market prospect.

Description

There is not the adjustable pitch cone moushroom valve of leakage from compressing

[technical field] the present invention relates to a kind of from compressing the adjustable pitch cone moushroom valve of nothing leakage, especially a kind of pressure of system self that relies on is fastened valve, sealing does not have leakage, but can regulate compressing certainly of flow and secured adjusted flow arbitrarily and not have the cone adjusting of leakage moushroom valve, be widely used in water, oil, gas, vapour, the particularly control of big flow in the pipeline of poisonous medium belongs to valve field.

[background technique] generally adopt gate valves, butterfly valve, ball valve, but the gate valve volume is big more in the control technology of traditional flow, the butterfly valve flow is uncontrollable, ball valve price height.

[21] the ZL patent No. 97105006.6,97105022.1 disclosed a kind of cam valve, though its volume is little, the energy self-tightening, the valve wearing and tearing are little, but because valve is vertical with the flow direction, the pressure loss is big, and the power during cam mechanism Open valve that it adopted is ascending, and required power is descending just opposite during with actual Open valve, owing to adopt four muscle guiding, thereby make Open valve need very big power.

[summary of the invention] the object of the present invention is to provide a kind of can dependence the pressure of system self fasten valve, sealing does not have leakage, volume is little, simple in structure, easily manufactured, cost is low, does not have the cone adjusting of leakage moushroom valve but can regulate compressing certainly of flow and secured adjusted flow arbitrarily, can be widely used in the control of the interior big flow of pipeline of water, oil, gas, vapour, particularly poisonous medium.

The present invention in order to achieve the above object, on the basis of comparative valve, but invented a kind of from compressing nothing leakage cone adjusting moushroom valve, manually there is not the adjustable pitch cone moushroom valve of leakage by flap (1), valve body (2), spool (3), rotating shaft (4), sealing (5), seat (6), sealed attachment from compressing, conical surface hole is consistent with the cone-apex angle of awl dish, cone-apex angle is 90 °--180 °, spool (3) is a scyewed joint with rotating shaft (4).

Rotating shaft (4) realizes sealed attachment with valve body (2) by sealing (5) and seat (6), the fastening connection of handwheel (9) is housed in the rotating shaft (4), seat (6) is contained in the top scyewed joint of valve body (2), have inner groove on the seat (6), stopper ring (7) is housed in the groove is slidingly connected, on the seat (6) stopping wheel (8) scyewed joint is arranged, it is characterized in that: have inner groove on the seat (6), stopper ring (7) is housed in the groove is slidingly connected, on the seat (6) stopping wheel (8) scyewed joint is arranged.

But have manually from compressing nothing leakage cone adjusting moushroom valve, electronic and intelligent three kinds, but electronic do not have the cone adjusting of leakage moushroom valve by motor replacement handwheel as shown in Figure 2 from compressing.

[description of drawings] but accompanying drawing 1 does not manually have the cone adjusting of leakage moushroom valve from compressing.

But accompanying drawing 2 is electronic from compressing nothing leakage cone adjusting moushroom valve.

Accompanying drawing 1 is depicted as embodiments of the invention.

[tool mode of execution] is below in conjunction with accompanying drawing (1), embodiments of the invention are further described: but manually there is not the cone adjusting of leakage moushroom valve by flap (1) from compressing, valve body (2), spool (3), rotating shaft (4), sealing (5), seat (6), stopper ring (7), stopping wheel (8), handwheel (9), cushion rubber (10) is formed, flap (1) is positioned at the bottom thread sealed attachment of valve body (2), flap (1) connects with spool (3) slide key, there is individual conical surface hole at the center of valve body (2), there is the awl dish at the middle part of spool (3), have aprons slot on the awl dish, cushion rubber (10) is housed on the aprons slot, the awl dish of spool (3) is by the conical surface hole sealed attachment of the cushion rubber on the aprons slot (10) with valve body (2), the other end of spool (3) has screw thread, with rotating shaft (4) scyewed joint, rotating shaft (4) realizes sealed attachment with valve body (2) by sealing (5) and seat (6), the fastening connection of handwheel (9) is housed in the rotating shaft (4), seat (6) is contained in the top scyewed joint of valve body (2), have inner groove on the seat (6), stopper ring (7) is housed in the groove to be slidingly connected, on the seat (6) stopping wheel (8) scyewed joint is arranged, current with pressure are entered by water intake, realize not having leakage from compressing the awl dish, and the awl dish design automatic compensation after can realizing wearing and tearing, press opening direction and rotate handwheel (9) drive rotating shaft (4) rotation, because spool (3) and rotating shaft (4) scyewed joint, spool (3) connects with flap (1) slide key again, so spool (3) can only move downward, awl dish on the spool (3) moves downward with speed, but realized manually not having the unlatching of leaking the cone adjusting moushroom valve from compressing, when being opened to suitable size fixedly the time, can tighten stopping wheel (8), stopper ring (7) will be by the top to a side, thereby pin rotating shaft (4), realized adjustable the fixing of opening of valves, what its opening of valves was adjustable fixedly is stepless, otherwise rotate handwheel (9) by the direction of closing, then can realize closing of valve, because sealing (5) is compensable sealing after the wearing and tearing of adopting, so valve is leak free, so but be not have the cone adjusting of leakage moushroom valve from compressing.

But it is electronic the same from compressing the situation of not having leakage cone adjusting moushroom valve.

But do not have the cone adjusting of leakage moushroom valve from compressing, be widely used in water, oil, gas, the various occasions of vapour, be the gate valve that continues, butterfly valve, the awl moushroom valve of the novel concept that occurs behind the ball valve is particularly suitable for the control of flow greatly in the pipeline, its compact structure, cost is low, and reliable performance has good market prospects.
