Abstract

The utility model provides a valve provided with a balancing cavity. A valve core assembly is installed at the upper portion of a valve body through a limiting nut, a sealing ring and a reed, and a bottom cover is installed at the lower portion of the valve body through a graphite gasket, a flat gasket and a bolt. The valve is novel and simple in structure, a part shape is simplified based on pressure balancing in a mode that inner threads and outer threads are matched, and the assembly working amount is decreased. The valve provided with the balancing cavity is suitable for application.

Description

The valve with counter balance pocket

Technical field

The utility model provides the valve of break-make medium, specifically has the valve of counter balance pocket.

Background technique

Current counter balance pocket valve body on the market, counter balance pocket structure is all to adopt screw assembling mode, and screw assembling mode and general, is assembled together pressing plate, sealing gasket, shell fragment and base plate by screw, exactly because also like this, can cause part to add man-hour, increase a lot of workloads, numerous tapped holes need to be processed successively, greatly reduce the efficiency of manufacturing, and due to the numerous screw of needs, also increased the installation time of product, made efficiency of assembling low.

Model utility content

The defect existing in order to overcome existing equilibrium valve, the utility model provides the valve with counter balance pocket.This valve, by Screw assembly, solves technical problem efficiently easy to assembly.

The scheme that the utility model technical solution problem adopts: mangetic core assembly is equipped with by stop nut, seal ring and reed in valve body top, is provided with bottom in valve body lower portion by Graphite pad, plain cushion and bolt.

Good effect, the utility model structural design is more novel, simple, and the mode cooperatively interacting by internal and external threads is realizing on balance pressure basis, has simplified the shape of part, has reduced the workload of assembling.Suitable conduct has the valve applications of counter balance pocket.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model

In figure, 1. stop nut, 2. seal ring, 3. reed, 4. valve body, 5. mangetic core assembly, 6. Graphite pad, 7. bottom, 8. plain cushion, 9. bolt.

Embodiment

According to the figure, mangetic core assembly 5 is equipped with by stop nut 1, seal ring 2 and reed 3 in valve body 4 tops, in valve body lower portion, by Graphite pad 6, plain cushion 8 and bolt 9, bottom 7 is installed.

Working principle:

Bottom assembly is contained on valve body, seal ring and reed are assembled in bottom assembly by stop nut, mangetic core assembly is contained on valve body through seal ring, thereby realized the assembling of valve counter balance pocket, because spool is conducting up and down, so spool is when upper and lower switch, the upper and lower pressure of spool offsets, and the suffered resistance of spool can be very little like this.Reduced the strength of final controlling element, increased the reliability of product and reduced cost.

Feature:

1, simple in structure, be easy to processing:

Due to the assembling mode of the utility model employing screw thread, both simple and practical, be convenient to again processing, improve the efficiency of processing with assembling, thereby improved manufacturing efficiency.

2, operational safety is strong

Due to Screw assembly structure of the present utility model, seal ring is stressed greatly, seal more reliably, promoted the quality of product.

Claims

1. the valve with counter balance pocket, is characterized in that: mangetic core assembly (5) is equipped with by stop nut (1) in valve body (4) top, and seal ring (2) is housed between stop nut and mangetic core assembly, at sealing ring lower potion, is lined with reed (3);

In valve body lower portion, bottom (7) is housed, above bottom and between valve body, is lined with Graphite pad (6), fixing by bolt (9) between bottom and valve body, between bolt and bottom, be lined with plain cushion (8).
