Abstract
The utility model relates to a plug type valve, which comprises a valve body and a valve core, wherein the valve core is arranged in the valve body, and has a trapezoid plug structure; the inner wall of the valve body is provided with a diversion groove; the diversion groove is positioned below a valve body water inlet, and is communicated with the valve body water inlet; the diversion groove extends downwards to the bottom of the valve body along the valve body; the bottom of the valve core is provided with three arc-shaped bumps of the same size; the three arc-shaped bumps are uniformly distributed on a circle taking the center of the bottom surface of the valve core as the circle center; and a water accommodating cavity is formed between the bottom of the valve core and the valve body through the arc-shaped bumps. According to the plug type valve, the valve core can be tightly contacted with the valve body, so that high sealing property between the valve core and the valve body is realized, and the service life is long.
Description
Technical field
The utility model belongs to the valve that uses in the petroleum chemical industry, and what be specifically related to is a kind of plug formula valve.
Background technique
The extensive use in petroleum chemical industry of plug formula valve; Mostly plug formula valve is water valve, i.e. water tap, and existing plug formula valve comprises valve body, spool, handle; Spool is trapezoidal plug shape; Be provided with supported spring between valve body and the spool bottom, spool withstood on the valve body, realize the sealing between spool and the valve body through supported spring.But this plug formula valve is through after using for a long time; Supported spring tends to elasticity to be reduced, and influences the sealing between spool and the valve body, shortens the working life of this valve; In addition; Because valve body and spool all are metals, the contact between valve body and the spool is rigid contact, and valve body and spool receive the influence of high temperature and oxidation solid dead phenomenon to occur easily.
Summary of the invention
The purpose of the utility model provides a kind of plug formula valve, and it is bad that it is used to solve existing plug formula valve seal effect, the problem that working life is short.
The utility model solves the technological scheme that its technical problem adopted: this plug formula valve comprises valve body, spool; Spool is contained in the valve body; Spool is trapezoidal plug shape; Valve interior wall is provided with guiding gutter, and guiding gutter is positioned at the below of valve inleting water mouth and communicates with the valve inleting water mouth, and guiding gutter extends to the valve body bottom to the lower edge valve body; Arc convex is arranged at the bottom of spool, and arc convex has three, and size is identical, and it is on the circle in the center of circle that three arc convex are evenly distributed on spool bottom center; Form water containing chamber through arc convex between spool bottom and the valve body.
Spool is that pottery is processed in the such scheme.
Beneficial effect:
1, forms water containing chamber through arc convex between the utility model spool bottom and the valve body; After the utility model is installed on the penstock; Water can get into the water containing chamber between spool bottom and the valve body along guiding gutter, utilizes hydraulic pressure that spool is upwards pushed up, and makes spool and valve body keep closely contacting; Realize the excellent sealing between spool and the valve body, long service life.
2, spool adopts pottery to process in the utility model, has avoided the phenomenon that metal valve body and metal spool are fixed together in the existing plug formula valve.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the worm's eye view of spool in the utility model.
1 valve body, 2 spools, 3 guiding gutters, 4 arc convex, 5 water intakes.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in Figure 1; This plug formula valve comprises valve body 1, spool 2, and spool 2 is that pottery is processed, and spool 2 is contained in the valve body 1; Spool 2 is trapezoidal plug shape; Valve body 1 inwall is provided with guiding gutter 3, and guiding gutter 3 is positioned at the below of valve inleting water mouth 5 and communicates with valve inleting water mouth 5, and guiding gutter 3 extends to the valve body bottom to the lower edge valve body; Arc convex 4 is arranged at the bottom of spool 2, and arc convex 4 makes between spool 2 bottoms and the valve body 1 and forms water containing chamber, and spool 2 is positioned at certain position; To obtain the pressure face of water to spool 2 bottoms; When valve was in closed condition, intraductal pressure all gathered below spool 2, made spool 2 fill in tightlyer.
As shown in Figure 2; The arc convex 4 of spool 2 bottoms has three in this mode of execution; Three arc convex, 4 sizes are identical, and three arc convex 4 are evenly distributed on spool 2 bottom center to be on the circle in the center of circle, can to guarantee spool 2 perpendicularity like this; Spool 2 is cooperated better with valve body 1, guarantee better tightness between spool 2 and the valve body 1.
The utility model is simple in structure, and cost is low, can be widely used in the chemical industry, also can be applicable in the family.
